Claim Rejections - 35 USC § 103
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.
Claims 1, 3, 4, 7, 10-12, 14, 15-17, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Wang (WO 2020191717) (citations based on attached English translation) in view of Zhu (US 20250203620).
Regarding claims 1 and 12, Wang teaches a wireless transmit/receive unit (WTRU) comprising a processor and a method performed by a wireless transmit/receive unit (WTRU), comprising:
determining to switch to an uplink notification channel based on a serving cell condition (Wang, ¶93 – paging failure triggers selection of another coverage mode; Wang, ¶¶86-87 – UE selects extended coverage [i.e. switches from normal coverage] based on a cell selection criterion; Wang, ¶3 and figure 2 – UE is in normal coverage in area A and switches to “an extended coverage channel” when in area B); and
sending an indication on the uplink notification channel . . . the indication being configured to indicate that the WTRU is no longer reachable on a paging channel. Wang, figure 3 (step 101) and ¶¶81-83 or figure 9 (step 101b) and ¶162 (UE sends its mode preference information to the access node, which informs the access node that the UE is reachable via an extended coverage mode [i.e. not reachable via normal coverage mode]).
While Wang teaches a coverage enhancement mode consisting of repeated uplink transmissions (Wang, ¶3 – claimed “uplink coverage enhancements”), Wang does not explicitly teach (1) “identifying uplink notification channel configuration information that comprises an indication of a set of resources associated with the uplink notification channel, a set of uplink coverage enhancements associated with the uplink notification channel, and an identifier associated with the WTRU” or (2) a UE transmitting data “based on the uplink notification channel configuration information.” However, Zhu also teaches a UE transmitting an indicator for changing from a first uplink channel to a second uplink channel. Zhu, ¶156. The second uplink channel may be configured based on information provided by the network. Zhu, ¶¶159, 173, 177 (e.g. DCI). Regarding (1), the DCI can specify a UE ID/index (Zhu, ¶209), identify resources for the second uplink channel (Zhu, ¶210), and a MCS index for the second uplink channel. Zhu, ¶206. Regarding (2), the UE then transmits its report via the defined second UL channel. Zhu, ¶181 (last sentence) and ¶¶185-190 (examples of attributes defined for the second UL channel). At the time of the effective filing date of the invention, it would have been obvious for one of ordinary skill in the art to have the network to define the extended coverage channel, taught by Wang, via the DCI, taught by Zhu, in order to ensure efficient UE-initiated reporting of a channel change. Zhu, ¶76.
Regarding claims 3 and 14, the combination of Wang and Zhu also teaches receiving the uplink notification channel configuration information in a configuration message. Zhu, e.g. ¶¶206-210 (UE receives attributes of second uplink channel in a DCI).
Regarding claims 4 and 15, the combination of Wang and Zhu also teaches sending an uplink notification channel capability indication configured to indicate the WTRU's capability to support uplink notification channel communication (Wang, ¶82 – UE informs access node that it supports extended coverage via its mode preference information); and
in response to the uplink notification channel capability indication, receiving the uplink notification channel configuration information. Zhu, ¶¶163, 166, 181 (the network’s DCI is sent based on the UE’s capability report [i.e. Wang’s mode preference information]).
Regarding claims 7 and 16, the combination of Wang and Zhu also teaches
applying the set of uplink coverage enhancements while transmitting on the uplink notification channel (Wang, ¶3 – “sending end that supports extended coverage, such as a terminal device or a base station, can repeatedly send data multiple times via an extended coverage channel under extended coverage”); and
identifying an uplink notification channel transmission occasion (Zhu, ¶178 – pre-configured PUCCH or PUSCH resources of the second UL channel for sending the UE’s report), wherein the indication configured to indicate that the WTRU is no longer reachable on the paging channel is sent during the uplink notification channel transmission occasion. Wang, figure 3 (step 101) and ¶¶81-83 or figure 9 (step 101b) and ¶162 (UE sends its mode preference information to the access node, which informs the access node that the UE is reachable via an extended coverage mode [i.e. not reachable via normal coverage mode]). At the time of the effective filing date of the invention, it would have been obvious for one of ordinary skill in the art to use the periodic/semi-persistent resources, taught by Zhu, to transmit the mode preference information, taught by Wang, in order to provide different transmission occasions for uplink transmissions based on fixed rules in the system’s specification. Zhu, ¶¶161-162.
Regarding claims 11 and 17, the combination of Wang and Zhu also teaches receive a downlink notification channel configuration indication that comprise an indication of a set of occasions associated with a downlink notification channel (Wang, ¶89 – UE receives extended coverage system message, which provides the configuration information of the downlink paging message; Wang, ¶91 – in one embodiment, the paging message is sent over the narrowband [i.e. a subset of the frequency occasions]); and
upon sending the indication on the uplink notification channel, monitor the downlink notification channel based on the configured set of occasions associated with the downlink notification channel. Wang, ¶88 (after the mode preference information in step 101, the UE monitors for a downlink paging message under the extended coverage mode [i.e. monitors the “extended coverage channel”]).
Regarding claims 10 and 20, the combination of Wang and Zhu also teaches wherein the switching to an uplink notification channel is determined based on at least one of: a failure to detect paging; a failure to detect a downlink reference signal; a number of detected downlink reference signal being less than a threshold value; a ratio of failed PDCCH vs. successful PDCCH receptions exceeding a threshold value; or a failure to identify a suitable cell. Wang, ¶¶85, 93 (if paging fails, another coverage mode is selected).
Claims 2, 6, 8, 13, and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Wang in view of Zhu (both of record) and further in view of Lei (US 20250358819).
Regarding claims 2 and 13, the combination of Wang and Zhu teaches the WTRU of claim 1, the method of claim 12, a UE operating in idle mode (Wang, ¶¶85, 133 – during cell selection, the UE is in an idle state), and changing coverage modes based on a “failure on the paging channel.” Wang, ¶93. The combination does not explicitly teach “receiving an indication to operate in at least one of the idle or the inactive mode; and while operating in the at least one of the idle or the inactive mode, monitoring the paging channel for a physical downlink control channel (PDCCH), [and terminating a session] is determined in response to a PDCCH detection failure . . . ” However, Lei teaches the following:
receiving an indication to operate in at least one of the idle or the inactive mode (Lei, figure 5 – in step 505, the RRC release message triggers the UE to operate in RRC inactive mode in step 510); and
while operating in the at least one of the idle or the inactive mode, monitoring the paging channel for a physical downlink control channel (PDCCH) (Lei, figure 5 – in step 515, the UE monitors a paging communication for an upcoming PDCCH in step 535), and
[terminating a session] is determined in response to a PDCCH detection failure. Lei, ¶175 (if a PDDCH is not received or decoded within the duration of a timer, the session is terminated by the UE); Lei, ¶176 (terminating the session may include selecting a different node).
At the time of the effective filing date of the invention, it would have been obvious for one of ordinary skill in the art to transition to a new coverage mode, as taught by the combination of Wang and Zhu, based on the failure to receive a PDCCH while in inactive mode, as taught by Lei, in order to conserve resources by freeing a resource previously allocated but will no longer because of a change in the channel quality.
Regarding claim 6, the combination of Wang and Zhu teaches the WTRU of claim 1, but does not explicitly teach the UE configured to “receive a release message to operate in at least one of an idle or an inactive mode, wherein the uplink notification channel configuration information is received in the release message.” However, Lei teaches a UE receiving an RRC release message, which triggers the UE to operate in an inactive mode and an uplink configuration to be used by the UE is included in the RRC release communication. Lei, figure 5 (steps 505 and 510) and ¶86. At the time of the effective filing date of the invention, it would have been obvious for one of ordinary skill in the art to receiving the uplink channel configuration attributes, taught by the combination of Wang and Zhu, within an RRC release message, as taught by Lei, in order to grant the UE resources for communication. Lei, ¶82.
Regarding claims 8 and 18, the combination of Wang and Zhu teaches the WTRU of claim 1, the method of claim 12, and “wherein the indication configured to indicate that the WTRU is no longer reachable on the paging channel.” Wang, figure 3 (step 101) and ¶¶81-83 or figure 9 (step 101b) and ¶162 (UE sends its mode preference information to the access node, which informs the access node that the UE is reachable via an extended coverage mode [i.e. not reachable via normal coverage mode]). The combination of Wang and Zhu does not explicitly teach the mode preference information being “sent using the identifier associated with the WTRU.” However, Lei teaches an uplink message sent with a UE identifier. Lei, e.g. ¶¶89 or 107 (random access message or RRC connection request message from UE includes its identifier). At the time of the effective filing date of the invention, it would have been obvious for one of ordinary skill in the art to include the identifier of the transmitting UE, as taught by Lei, within the mode preference information, transmitted by the combination of Wang and Zhu, in order to enable the network node to identify which user device is seeking communicative coupling with the network node.
Claims 5, 9, and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Wang in view of Zhu (both of record) and further in view of Phuyal (US 20220338159).
Regarding claim 5, the combination of Wang and Zhu teaches the WTRU of claim 1 and wherein the processor is further configured to:
send an uplink notification channel capability indication configured to indicate the WTRU's capability to support uplink notification channel communication (Wang, ¶82 - “the terminal device supporting the extended coverage may send the mode preference information to the access node”); and
in response to the uplink notification channel capability indication, receive downlink notification channel configuration information Wang, ¶¶88, 89 (after transmitting the mode preference information in step 101, receives the extended coverage system message from the access node),
wherein the downlink notification channel configuration information is configured to indicate a set of occasions associated with monitoring a downlink notification channel . . . Wang, ¶89 (UE receives extended coverage system message, which provides the configuration information of the downlink paging message); Wang, ¶91 (in one embodiment, the paging message is sent over the narrowband [i.e. a subset of the frequency occasions]).
The combination of Wang and Zhu does not explicitly teach a downlink communication indicates “at least notification alert characteristic.” However, Phuyal teaches a network device transmitting a pre-paging alert to the UE, which alerts the UE to an upcoming paging message. Phuyal, ¶133. At the time of the effective filing date of the invention, it would have been obvious for one of ordinary skill in the art to include a pre-paging alert, as taught by Phuyal, within the extended coverage system message, taught by the combination of Wang and Zhu, in order to inform the UE of an upcoming downlink transmission when the channel conditions are poor. Id. at ¶133.
Regarding claims 9 and 19, the combination of Wang and Zhu teaches the WTRU of claim 1 and the method of claim 12, but does not explicitly teach “determining whether to switch to an uplink notification channel based on at least one of: whether an uplink transmission has failed; a number of failed uplink transmissions; a number of failed uplink transmissions within a time period; whether a random access has failed; a number of failed random access attempts; or whether the WTRU has exceeded power ramping.” However, Phuyal teaches a UE declaring a paging failure after a threshold amount of uplink transmissions are attempted. Phuyal, ¶128. At the time of the effective filing date of the invention, it would have been obvious for one of ordinary skill in the art to transition to the “extended coverage channel,” taught by the combination of Wang and Zhu, based on the paging failure, taught by Phuyal, in order to implement a technique to improve coverage and reception of the paging message. Phuyal, ¶133.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure includes Jha, which addresses poor coverage for paging and Saha, in which the UE monitors a second pre-paging channel if paging fails on a first channel.
