Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim 1, 5-6, 8-10, 17-18, and 37-38 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Yi et al. (US 2019/0260530), hereinafter Yi.
Regarding Claim 1, Yi teaches: A communication method, performed by a network device and comprising: configuring a measurement bandwidth and a subband of a carrier: “UE-specific bandwidth for DL/UL according to an embodiment of the present invention is described. Control subband used for Msg4 may be used for UE-specific search space (USS), until it is reconfigured. In Msg3, necessary channel state information (CSI) feedback may be delivered for supporting localized mapping. If any feedback is not sufficient, first distributed mapping may be used for search space for Msg4 and default USS. Default data subband for USS may be defined in M-SB in which Msg4 control subband is configured until it is reconfigured” (Yi ¶ 0100), and communicating with a user equipment (UE) via the subband: “In step S120, the UE performs communication with the network via the at least one data subband. One data subband consists of contiguous or non-contiguous PRBs” (Yi ¶ 0319); receiving a measurement value of the subband fed back by the UE: “Aperiodic CSI request may be requested on one or more configured subbands, and for the deactivated subbands, only wideband CSI measurement within the subband (i.e. wideband channel quality indictor (CQI)/precoding matrix indicator (PMI) over the entire subband) may be reported” (Yi ¶ 0174); adjusting subband configuration corresponding to the carrier according to the measurement value of the subband: “when bandwidth adaptation is applied, first, a UE may be activated or deactivated with secondary RF (It may also be possible to activate/deactivate third or fourth RF as well). In terms of activation/deactivation, MAC CE and/or RRC and/or dynamic signaling via DCI or separate signaling may be used. Another approach is to leave this up to UE implementation and no explicit activation/deactivation of RF procedure is supported. Depending on monitoring bandwidth, a UE may switch off or on some of RFs. In this case, depending on UE capability signaling on bandwidth, the network may determine the bandwidth that the UE can support/can be configured with” (Yi ¶ 0230).
Regarding Claim 5, Yi teaches: The method according to claim 1, wherein the network device receives a plurality of the measurement values fed back by the UE: “Wideband measurement across multiple RF may also be considered and aggregated/average RRM measurement over multiple RF may be reported, or separate/individual RRM measurement may be reported per RF” (Yi ¶ 0235), meaning Yi’s disclosure supports both aggregated reporting as well as reporting each RRM measurement per subband; wherein adjusting the subband configuration corresponding to the carrier according to the measurement value of the subband comprises: making a decision based on one measurement value in the plurality of the measurement values, or making a comprehensive decision based on the plurality of the measurement values to adjust the subband configuration: “Regardless of which options are considered, for better management, the candidate RF bandwidth may be constructed in a nested manner, e.g. {M MHz, M*2 MHz, M*4 MHz . . . }. The idea is to construct minimum system bandwidth subband, and support different UE RF bandwidth by aggregating multiple minimum system bandwidth subbands . . . UEs with different bandwidth may be treated differently. For example, RRM measurement requirement may be different based on UE supported bandwidth. For example, RRM measurement duration or the required duration to report RRM measurement may be relaxed based on the supported bandwidth. Overall RRM measurement requirement may be based on the nominal bandwidth” (Yi ¶ 0267 and 0270).
Regarding Claim 6, Yi teaches: The method according to claim 1, further comprising: sending the subband configuration adjusted to the UE: “In terms of bandwidth adaptation, based on the knowledge of UE RFs, the network may also indicate the required number of RFs and its intended center frequency. In other words, when bandwidth adaptation is applied, first, a UE may be activated or deactivated with secondary RF (It may also be possible to activate/deactivate third or fourth RF as well). In terms of activation/deactivation, MAC CE and/or RRC and/or dynamic signaling via DCI or separate signaling may be used. Another approach is to leave this up to UE implementation and no explicit activation/deactivation of RF procedure is supported. Depending on monitoring bandwidth, a UE may switch off or on some of RFs. In this case, depending on UE capability signaling on bandwidth, the network may determine the bandwidth that the UE can support/can be configured with” (Yi ¶ 0230).
Regarding Claim 8, Yi teaches: The method according to claim 1, further comprising: sending the subband configuration to the UE via a configuration signaling: “for each control subband, a set of data subbands which control subband may schedule may be indicated. If there is only one data subband, in resource allocation or additional field on data subband index may be omitted. If there are more than one data subbands, some indication on subband may be necessary. However, this may lead variable DCI size depending on the configured data subband. To address this, alternative approach is to assume that any control subband can schedule any data subband, and thus, the number of configured data subband to the UE is assumed for all resource allocation” (Yi ¶ 0125).
Regarding Claim 9, Yi teaches: The method according to claim 8, wherein the configuration signaling is a radio resource control (RRC) common signaling, a RRC dedicated signaling: “When a UE is reconfigured with control region for USS, control subband for Msg4 may be used as a fallback purpose. In the configuration, search space split between new USS and default USS may be indicated, or a UE may need to search both until radio resource control (RRC) reconfiguration is completed where search space is split equally between two search space” (Yi ¶ 0100) or a downlink control information (DCI) signaling: “for each control subband, a set of data subbands which control subband may schedule may be indicated. If there is only one data subband, in resource allocation or additional field on data subband index may be omitted. If there are more than one data subbands, some indication on subband may be necessary. However, this may lead variable DCI size depending on the configured data subband. To address this, alternative approach is to assume that any control subband can schedule any data subband, and thus, the number of configured data subband to the UE is assumed for all resource allocation” (Yi ¶ 0125).
Regarding Claim 10, Yi teaches: A communication method, applied to UE and comprising: receiving signals sent by a network device via subbands in a measurement bandwidth based on subband configuration; measuring communication quality according to the signals received to generate a measurement value of each subband corresponding to the UE: “UE-specific bandwidth for DL/UL according to an embodiment of the present invention is described. Control subband used for Msg4 may be used for UE-specific search space (USS), until it is reconfigured. In Msg3, necessary channel state information (CSI) feedback may be delivered for supporting localized mapping. If any feedback is not sufficient, first distributed mapping may be used for search space for Msg4 and default USS. Default data subband for USS may be defined in M-SB in which Msg4 control subband is configured until it is reconfigured” (Yi ¶ 0100); sending the measurement value of the subband to the network device: “Aperiodic CSI request may be requested on one or more configured subbands, and for the deactivated subbands, only wideband CSI measurement within the subband (i.e. wideband channel quality indictor (CQI)/precoding matrix indicator (PMI) over the entire subband) may be reported” (Yi ¶ 0174).
Regarding Claim 15, Yi teaches: The method according to claim 10, further comprising: sending an identifier of the measurement bandwidth and an identifier of the subband to the network device: “if a UE can aggregate baseband capability for different carriers to one carrier, the UE may report the aggregated baseband capability per baseband. For inter/intra-band CA, the total baseband capability may be indicated which may be divided to aggregated carriers by the network. If a UE cannot support flexible partitioning of capabilities between carriers, the UE may also indicate baseband capability per band for each band combination. For each band combination, supported RF bandwidth on each band may also be indicated” (Yi ¶ 0139).
Regarding Claim 17, Yi teaches: The method according to claim 10, further comprising: receiving the subband configuration sent by the network device via a configuration signaling: “for each control subband, a set of data subbands which control subband may schedule may be indicated. If there is only one data subband, in resource allocation or additional field on data subband index may be omitted. If there are more than one data subbands, some indication on subband may be necessary. However, this may lead variable DCI size depending on the configured data subband. To address this, alternative approach is to assume that any control subband can schedule any data subband, and thus, the number of configured data subband to the UE is assumed for all resource allocation” (Yi ¶ 0125).
Regarding Claim 18, Yi teaches: The method according to claim 17, wherein the configuration signaling is a radio resource control (RRC) common signaling, a RRC dedicated signaling: “When a UE is reconfigured with control region for USS, control subband for Msg4 may be used as a fallback purpose. In the configuration, search space split between new USS and default USS may be indicated, or a UE may need to search both until radio resource control (RRC) reconfiguration is completed where search space is split equally between two search space” (Yi ¶ 0100) or a downlink control information (DCI) signaling: “for each control subband, a set of data subbands which control subband may schedule may be indicated. If there is only one data subband, in resource allocation or additional field on data subband index may be omitted. If there are more than one data subbands, some indication on subband may be necessary. However, this may lead variable DCI size depending on the configured data subband. To address this, alternative approach is to assume that any control subband can schedule any data subband, and thus, the number of configured data subband to the UE is assumed for all resource allocation” (Yi ¶ 0125).
Regarding Claim 37, Yi teaches: A communication device, comprising: a processor; and a memory; wherein a computer program is stored in the memory, and the processor executes the computer program stored in the memory to cause the device: “A network node 800 includes a processor 810, a memory 820 and a transceiver 830. The processor 810 may be configured to implement proposed functions, procedures and/or methods described in this description. Layers of the radio interface protocol may be implemented in the processor 810. The memory 820 is operatively coupled with the processor 810 and stores a variety of information to operate the processor 810” (Yi ¶ 0325) to: configure a measurement bandwidth and a subband of a carrier: “UE-specific bandwidth for DL/UL according to an embodiment of the present invention is described. Control subband used for Msg4 may be used for UE-specific search space (USS), until it is reconfigured. In Msg3, necessary channel state information (CSI) feedback may be delivered for supporting localized mapping. If any feedback is not sufficient, first distributed mapping may be used for search space for Msg4 and default USS. Default data subband for USS may be defined in M-SB in which Msg4 control subband is configured until it is reconfigured” (Yi ¶ 0100), and communicate with a user equipment (UE) via the subband: “In step S120, the UE performs communication with the network via the at least one data subband. One data subband consists of contiguous or non-contiguous PRBs” (Yi ¶ 0319); receive a measurement value of the subband fed back by the UE: “Aperiodic CSI request may be requested on one or more configured subbands, and for the deactivated subbands, only wideband CSI measurement within the subband (i.e. wideband channel quality indictor (CQI)/precoding matrix indicator (PMI) over the entire subband) may be reported” (Yi ¶ 0174); adjust subband configuration corresponding to the carrier according to the measurement value of the subband: “when bandwidth adaptation is applied, first, a UE may be activated or deactivated with secondary RF (It may also be possible to activate/deactivate third or fourth RF as well). In terms of activation/deactivation, MAC CE and/or RRC and/or dynamic signaling via DCI or separate signaling may be used. Another approach is to leave this up to UE implementation and no explicit activation/deactivation of RF procedure is supported. Depending on monitoring bandwidth, a UE may switch off or on some of RFs. In this case, depending on UE capability signaling on bandwidth, the network may determine the bandwidth that the UE can support/can be configured with” (Yi ¶ 0230).
Regarding Claim 38, Yi teaches: A communication device, comprising: a processor; and a memory; wherein a computer program is stored in the memory, and the processor executes the computer program stored in the memory to cause the device to execute the method according to claim 10: “A UE 900 includes a processor 910, a memory 920 and a transceiver 930.

Layers of the radio interface protocol may be implemented in the processor 910. The memory 920 is operatively coupled with the processor 910 and stores a variety of information to operate the processor 910” (Yi ¶ 0326).
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 2-3 and 11-12 are rejected under 35 U.S.C. 103 as being unpatentable over Yi as applied to claims 1 and 10 above, and further in view of Abdelghaffar et al. (US 2022/0022183), hereinafter Abdelghaffar.
Regarding Claim 2, Yi teaches: The method according to claim 1.
Yi does not teach: the subband configuration is used to configure types of a plurality of the subbands in the carrier, wherein the types of the subbands comprise an uplink type, a downlink type and a flexible type.
Regarding Claim 2, Abdelghaffar teaches: the subband configuration is used to configure types of a plurality of the subbands in the carrier, wherein the types of the subbands comprise an uplink type, a downlink type and a flexible type: “The flexible slot within the flexible part of the frame structure may have separate subband resources where the bandwidth of each subband may be different and/or the subband type being UL, DL, or flexible” (Abdelghaffar ¶ 0074).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the disclosure of Yi with Abdelghaffar for the purpose of reducing interference. According to Abdelghaffar: “It may also be beneficial to split the channel bandwidth to uplink and downlink bands and utilize part of the available bandwidth to reduce and/or control interference. Moreover, it may be beneficial to partition flexible slots” (Abdelghaffar ¶ 0068).
Regarding Claim 3, Yi teaches: The method according to claim 2.
Yi does not teach: wherein when the type of the subband is the downlink type, the network device transmits data to the UE on the subband; or when the type of the subband is the uplink type, the network device receives data transmitted by the UE on the subband; or when the type of the subband is the flexible type, the network device configures the subband for uplink transmission, downlink transmission, or null transmission via a configuration signaling.
Regarding Claim 3, Abdelghaffar teaches: wherein when the type of the subband is the downlink type, the network device transmits data to the UE on the subband; or when the type of the subband is the uplink type, the network device receives data transmitted by the UE on the subband; or when the type of the subband is the flexible type, the network device configures the subband for uplink transmission, downlink transmission, or null transmission via a configuration signaling: “a common frame structure may include downlink transmissions at a certain time and uplink transmissions at a certain time. For instance, each slot over a certain time period may be downlink transmissions, and each slot over another time period may be uplink transmissions. An operator may align the slots to the baseline direction or blank a flexible portion” (Abdelghaffar ¶ 0060), meaning the DL slots correspond to downlink transmissions, the UL slots correspond to uplink transmissions, and blank slots correspond to null transmissions: “downlink blanking is when a downlink slot is blanked or left empty to avoid interference. So in an attempt to avoid cross interference, one network or base station may blank a slot or not send data in the slot. In some aspects, one or more symbols in the slot in the frame may be blanked, such as in an ‘S’ slot structure” (Abdelghaffar ¶ 0065).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the disclosure of Yi with Abdelghaffar for the purpose of reducing interference. According to Abdelghaffar: “It may also be beneficial to split the channel bandwidth to uplink and downlink bands and utilize part of the available bandwidth to reduce and/or control interference. Moreover, it may be beneficial to partition flexible slots” (Abdelghaffar ¶ 0068).
Regarding Claim 11, Yi teaches: The method according to claim 10.
Yi does not teach: the subband configuration is used to configure types of a plurality of the subbands in the carrier, wherein the types of the subbands comprise an uplink type, a downlink type and a flexible type.
Regarding Claim 11, Abdelghaffar teaches: the subband configuration is used to configure types of a plurality of the subbands in the carrier, wherein the types of the subbands comprise an uplink type, a downlink type and a flexible type: “The flexible slot within the flexible part of the frame structure may have separate subband resources where the bandwidth of each subband may be different and/or the subband type being UL, DL, or flexible” (Abdelghaffar ¶ 0074).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the disclosure of Yi with Abdelghaffar for the purpose of reducing interference. According to Abdelghaffar: “It may also be beneficial to split the channel bandwidth to uplink and downlink bands and utilize part of the available bandwidth to reduce and/or control interference. Moreover, it may be beneficial to partition flexible slots” (Abdelghaffar ¶ 0068).
Regarding Claim 12, Yi teaches: The method according to claim 11.
Yi does not teach: when the type of the subband is the downlink type, the UE receives data transmitted by the network device on the subband; or when the type of the subband is the uplink type, the UE transmits data to the network device on the subband; or when the type of the subband is the flexible type, the network device configures the subband for uplink transmission, downlink transmission, or null transmission via a configuration signaling.
Regarding Claim 12, Abdelghaffar teaches: when the type of the subband is the downlink type, the UE receives data transmitted by the network device on the subband; or when the type of the subband is the uplink type, the UE transmits data to the network device on the subband; or when the type of the subband is the flexible type, the network device configures the subband for uplink transmission, downlink transmission, or null transmission via a configuration signaling: “a common frame structure may include downlink transmissions at a certain time and uplink transmissions at a certain time. For instance, each slot over a certain time period may be downlink transmissions, and each slot over another time period may be uplink transmissions. An operator may align the slots to the baseline direction or blank a flexible portion” (Abdelghaffar ¶ 0060), meaning the DL slots correspond to downlink transmissions, the UL slots correspond to uplink transmissions, and blank slots correspond to null transmissions: “downlink blanking is when a downlink slot is blanked or left empty to avoid interference. So in an attempt to avoid cross interference, one network or base station may blank a slot or not send data in the slot. In some aspects, one or more symbols in the slot in the frame may be blanked, such as in an ‘S’ slot structure” (Abdelghaffar ¶ 0065).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the disclosure of Yi with Abdelghaffar for the purpose of reducing interference. According to Abdelghaffar: “It may also be beneficial to split the channel bandwidth to uplink and downlink bands and utilize part of the available bandwidth to reduce and/or control interference. Moreover, it may be beneficial to partition flexible slots” (Abdelghaffar ¶ 0068).
Claims 4, 7, and 16 are rejected under 35 U.S.C. 103 as being unpatentable over Yi as applied to claims 1 and 10 above, and further in view of Pezeshki et al. (US 2021/0176654), hereinafter Pezeshki.
Regarding Claim 4, Yi teaches: The method according to claim 1.
Yi does not teach: adjusting the subband configuration corresponding to the carrier according to the measurement value of the subband comprises: determining whether the measurement value of the subband reaches a first threshold corresponding to the subband; in case that the first threshold corresponding to the subband is reached, adjusting the subband configuration according to the measurement value of the subband.
Regarding Claim 4, Pezeshki teaches: adjusting the subband configuration corresponding to the carrier according to the measurement value of the subband comprises: determining whether the measurement value of the subband reaches a first threshold corresponding to the subband: “The UE may identify an interference level for an interference measurement by determining which interference range the interference measurement falls within. For example, the UE may identify a low interference level for an interference measurement that falls within the interference range associated with the low interference level. As another example, the UE may identify a medium interference level for an interference measurement that falls within the interference range associated with the medium interference level. As another example, the UE may identify a high interference level for an interference measurement that falls within the interference range associated with the high interference level” (Pezeshki ¶ 0060); in case that the first threshold corresponding to the subband is reached, adjusting the subband configuration according to the measurement value of the subband: “the BS may schedule a retransmission occasion for a PDSCH communication. The BS may receive the SRSs from the UE on the plurality of subbands, and may determine that reception of the SRSs indicates a NACK for the PDSCH communication. The BS may schedule the retransmission occasion based at least in part on the interference levels in each of the plurality of subbands. For example, the BS may schedule the retransmission occasion to be in the subband with the lowest interference level, to be in a subband with an interference level that satisfies an interference level threshold (e.g., to be in a subband with a low interference level), and/or the like” (Pezeshki ¶ 0066).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the disclosure of Yi with Pezeshki for the purpose of allowing the base station to reallocate resources depending on the interference levels at different subbands. According to Pezeshki: “the BS may receive the SRSs in each of the plurality of subbands, may identify the interference level in each of the plurality of subbands based at least in part on the SRS sequences of the SRSs, and may perform one or more actions based at least in part on the interference levels in each of the plurality of subbands. For example, the BS may schedule a retransmission of a PDSCH communication from a subband having a high interference level to another subband having a low interference level” (Pezeshki ¶ 0024).
Regarding Claim 7, Yi teaches: The method according to claim 1.
Yi does not teach: the measurement value of the subband comprises one or more of a reference signal received power (RSRP), a reference signal received quality (RSRQ), a received signal strength indication (RSSI), or a signal-to-noise and interference ratio (SINR).
Regarding Claim 7, Pezeshki teaches: the measurement value of the subband comprises one or more of a reference signal received power (RSRP), a reference signal received quality (RSRQ), a received signal strength indication (RSSI): “On the uplink, at UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, CQI, etc.) from controller/processor 280” (Pezeshki ¶ 0045).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the disclosure of Yi with Pezeshki for the purpose of allowing the base station to reallocate resources depending on the interference levels at different subbands. According to Pezeshki: “the BS may receive the SRSs in each of the plurality of subbands, may identify the interference level in each of the plurality of subbands based at least in part on the SRS sequences of the SRSs, and may perform one or more actions based at least in part on the interference levels in each of the plurality of subbands. For example, the BS may schedule a retransmission of a PDSCH communication from a subband having a high interference level to another subband having a low interference level” (Pezeshki ¶ 0024).
Regarding Claim 16, Yi teaches: The method according to claim 10.
Yi does not teach: the measurement value of the subband comprises one or more of a reference signal received power (RSRP), a reference signal received quality (RSRQ), a received signal strength indication (RSSI), or a signal-to-noise and interference ratio (SINR).
Regarding Claim 16, Pezeshki teaches: the measurement value of the subband comprises one or more of a reference signal received power (RSRP), a reference signal received quality (RSRQ), a received signal strength indication (RSSI): “On the uplink, at UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, CQI, etc.) from controller/processor 280” (Pezeshki ¶ 0045).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the disclosure of Yi with Pezeshki for the purpose of allowing the base station to reallocate resources depending on the interference levels at different subbands. According to Pezeshki: “the BS may receive the SRSs in each of the plurality of subbands, may identify the interference level in each of the plurality of subbands based at least in part on the SRS sequences of the SRSs, and may perform one or more actions based at least in part on the interference levels in each of the plurality of subbands. For example, the BS may schedule a retransmission of a PDSCH communication from a subband having a high interference level to another subband having a low interference level” (Pezeshki ¶ 0024).
Claims 13-14 are rejected under 35 U.S.C. 103 as being unpatentable over Yi as applied to claim 10 above, and further in view of Liu et al. (US 2018/0234896), hereinafter Liu.
Regarding Claim 13, Yi teaches: The method according to claim 10.
Yi does not teach: sending the measurement value of the subband to the network device comprises: determining whether the measurement value of the subband is greater than or equal to a second threshold corresponding to the subband; in case that the measurement value of the subband is greater than or equal to the second threshold corresponding to the subband, sending the measurement value of the subband to the network device; in case that the measurement value of the subband is less than the second threshold corresponding to the subband, not sending the measurement value of the subband to the network device.
Regarding Claim 13, Liu teaches: sending the measurement value of the subband to the network device comprises: determining whether the measurement value of the subband is greater than or equal to a second threshold corresponding to the subband; in case that the measurement value of the subband is greater than or equal to the second threshold corresponding to the subband, sending the measurement value of the subband to the network device; in case that the measurement value of the subband is less than the second threshold corresponding to the subband, not sending the measurement value of the subband to the network device: “There may be various trigger conditions for reporting a measurement report of a subband. For example, a measurement report is reported when a subband with a strongest signal changes, or a measurement report is reported when signal strength of a subband reaches a threshold” (Liu ¶ 0169). In other words, when the UE detects signal strength of a subband has reached a threshold, the measurement value is reported. Otherwise a measurement report is not sent.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the disclosure of Yi with Liu for the purpose of allowing a UE to trigger a subband switch when a requirement of the UE is not met. According to Liu: “To resolve a prior-art problem that switching between different subbands by UE is not defined, embodiments of the present application provide a subband switching method, so that UE can switch to a different subband, and a current requirement of the UE is met” (Liu ¶ 0005).
Regarding Claim 14, Yi teaches: The method according to claim 13, wherein the UE corresponds to a plurality of subbands : “for each control subband, a set of data subbands which control subband may schedule may be indicated. If there is only one data subband, in resource allocation or additional field on data subband index may be omitted. If there are more than one data subbands, some indication on subband may be necessary. However, this may lead variable DCI size depending on the configured data subband. To address this, alternative approach is to assume that any control subband can schedule any data subband, and thus, the number of configured data subband to the UE is assumed for all resource allocation” (Yi ¶ 0125), in other words, the UE of Yi is concerned with multiple subbands.
Yi does not teach:, and sending the measurement value of the subband to the network device comprises: determining whether the measurement value of the subband is greater than or equal to a second threshold corresponding to the subband; in case that the measurement value of the subband is greater than or equal to the second threshold corresponding to the subband, sending the measurement value of the subband to the network device; in case that the measurement value of the subband is less than the second threshold corresponding to the subband, not sending the measurement value of the subband to the network device.
Regarding Claim 14, Liu teaches: wherein the UE corresponds to a plurality of subbands, sending the measurement value of the subband to the network device comprises: determining whether the measurement value of the subband is greater than or equal to a second threshold corresponding to the subband; in case that the measurement value of the subband is greater than or equal to the second threshold corresponding to the subband, sending the measurement value of the subband to the network device; in case that the measurement value of the subband is less than the second threshold corresponding to the subband, not sending the measurement value of the subband to the network device: “There may be various trigger conditions for reporting a measurement report of a subband. For example, a measurement report is reported when a subband with a strongest signal changes, or a measurement report is reported when signal strength of a subband reaches a threshold” (Liu ¶ 0169). In other words, when the UE detects signal strength of a subband has reached a threshold, the measurement value is reported. Otherwise a measurement report is not sent.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the disclosure of Yi with Liu for the purpose of allowing a UE to trigger a subband switch when a requirement of the UE is not met. According to Liu: “To resolve a prior-art problem that switching between different subbands by UE is not defined, embodiments of the present application provide a subband switching method, so that UE can switch to a different subband, and a current requirement of the UE is met” (Liu ¶ 0005).
