Claim Rejections - 35 USC § 102
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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(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.
Claims 1-5, 9, 11-13, and 16-17 are rejected under 35 U.S.C. 102(a)(2) as being unpatentable by Shehata et. al. (U.S. Pat. Pub. 2024/0022982), herein referred to as “Shehata”.
Regarding Claim 1,
Shehata discloses: A method comprising: receiving, by a wireless device, one or more messages indicating: one or more reference signal configuration parameters for activation of a secondary cell and a unified transmission configuration indicator (TCI) state reference parameter indicating a reference bandwidth part (BWP) of a reference cell
[0115] For example, in some implementations, the L3 control signaling 215 (e.g., RRC message) may include a set of information elements associated with a set of candidate SCell configurations (e.g., SCellActivationRS-Config), a set of candidate PCell configurations (e.g., PCellActivationRS-Config), or both, that may be used for communications with SCells and PCells, respectively. The respective SCell and PCell configurations may each be associated with corresponding SCell identifiers (e.g., SCellActivationRS-Ids) and PCell identifiers (e.g., PCellActivationRS-Ids), respectively. In some aspects, SCell and PCell identifiers may be indicated via tracking reference signal (TRS) identifiers (TRS IDs), as will be described in further detail herein.
[0117] By way of another example, each SCell configuration and/or PCell configuration may include QCL information (e.g., gel-Info), which may include a list of references to TCI states for providing the QCL source and QCL type for each NZP-CSI-RS-Resource listed in NZP-CSI-RS-Resources of the NZP-CSI-RS-ResourceSet indicated by resourceSet. Each TCI-StateId may refer to the TCI-State which has this value for tci-StateId and is defined in tci-StatesToAddModList in the PDSCH-Config included in the BWP-Downlink of the respective serving cell indicated by firstActiveDownlinkBWP-Id in the ServingCellConfig in which the respective information element is included. In some implementations, a first entry in qcl-info may correspond to first entry in nzp-CSI-RS-Resources of that NZP-CSI-RS-ResourceSet.
Note: The “configuration parameters” are found in Applicant’s specification Figures 19B, where this reference has these parameters in paragraph [0115]. As for the “TCI state reference parameter indicating a reference BWP of a reference cell”, Applicant’s specification Figure 19C has these parameters, to which paragraph [0117] contains this information, particularly located in the PDSCH-config information.
receiving a message indicating a first reference signal configuration parameter, of the one or more reference signal configuration parameters, wherein the first reference signal configuration parameter comprises: a TCI state index indicating a first TCI state in the reference BWP of the reference cell; and
[0115] For example, in some implementations, the L3 control signaling 215 (e.g., RRC message) may include a set of information elements associated with a set of candidate SCell configurations (e.g., SCellActivationRS-Config), a set of candidate PCell configurations (e.g., PCellActivationRS-Config), or both, that may be used for communications with SCells and PCells, respectively. The respective SCell and PCell configurations may each be associated with corresponding SCell identifiers (e.g., SCellActivationRS-Ids) and PCell identifiers (e.g., PCellActivationRS-Ids), respectively. In some aspects, SCell and PCell identifiers may be indicated via tracking reference signal (TRS) identifiers (TRS IDs), as will be described in further detail herein.
[0117] By way of another example, each SCell configuration and/or PCell configuration may include QCL information (e.g., gel-Info), which may include a list of references to TCI states for providing the QCL source and QCL type for each NZP-CSI-RS-Resource listed in NZP-CSI-RS-Resources of the NZP-CSI-RS-ResourceSet indicated by resourceSet. Each TCI-StateId may refer to the TCI-State which has this value for tci-StateId and is defined in tci-StatesToAddModList in the PDSCH-Config included in the BWP-Downlink of the respective serving cell indicated by firstActiveDownlinkBWP-Id in the ServingCellConfig in which the respective information element is included. In some implementations, a first entry in qcl-info may correspond to first entry in nzp-CSI-RS-Resources of that NZP-CSI-RS-ResourceSet.
Note: Paragraph [0442] of Applicant’s specification states that “The TCI state index/identifier (or the TCI state) may be defined either in tci-StatesToAddModList or dl-OrJointTCI-StateList in one or more PDSCH configuration parameters (e.g., PDSCH-Config in FIG. 19C) included in the downlink BWP (e.g., the BWP-Downlink) of the cell.” Here, paragraph [0117] provides this parameter.

[0117] By way of another example, each SCell configuration and/or PCell configuration may include QCL information (e.g., gel-Info), which may include a list of references to TCI states for providing the QCL source and QCL type for each NZP-CSI-RS-Resource listed in NZP-CSI-RS-Resources of the NZP-CSI-RS-ResourceSet indicated by resourceSet. Each TCI-StateId may refer to the TCI-State which has this value for tci-StateId and is defined in tci-StatesToAddModList in the PDSCH-Config included in the BWP-Downlink of the respective serving cell indicated by firstActiveDownlinkBWP-Id in the ServingCellConfig in which the respective information element is included. In some implementations, a first entry in qcl-info may correspond to first entry in nzp-CSI-RS-Resources of that NZP-CSI-RS-ResourceSet.
Note: The “resource set index” is the NZP-CSI-RS-Resource set, since it contains a list of reference signals.
receiving, via a first active downlink BWP of the SCell and based on the first TCI state, the one or more reference signals (CSI-RS)
[0117] By way of another example, each SCell configuration and/or PCell configuration may include QCL information (e.g., gel-Info), which may include a list of references to TCI states for providing the QCL source and QCL type for each NZP-CSI-RS-Resource listed in NZP-CSI-RS-Resources of the NZP-CSI-RS-ResourceSet indicated by resourceSet.

In some implementations, a first entry in qcl-info may correspond to first entry in nzp-CSI-RS-Resources of that NZP-CSI-RS-ResourceSet.
Note: The “receiving” step is demonstrated in Figure 2 by L3 signaling.
Regarding Claim 2,
Shehata discloses: The method of claim 1, wherein the receiving the one or more reference signals comprises determining one or more radio link qualities of the one or more reference signals.
[0166] At 820, the UE 115-b may transmit a measurement report to the first serving cell 805-a. The measurement report may include an L1 measurement report, such as an RSRP measurement report. The L1 measurement report may include measurements performed by the UE 115-b on signals received from different serving cells 805, such as the first serving cell 805-a, the second serving cell 805-b, and the like. Measurements included in the measurement report may be associated with serving cells 805 that are currently activated at the UE 115-b (such as the first serving cell 805-a), serving cells that are not currently activated at the UE 115-b (such as the second serving cell 805-b) (e.g., candidate serving cells), or both. In this regard, the L1 measurement report may be used by the first serving cell 805-a to evaluate a relative quality of wireless communications between the UE 115-b and other serving cells 805, and to determine whether to trigger handover procedures to other serving cells 805.
Note: The “radio link quality” is RSRP (refer to Applicant’s specification paragraph [0491]) which are associated with serving cells, and are determined as part of the measurement reporting.
Regarding Claim 3,
Shehata discloses: The method of claim 1, wherein the SCell is deactivated before the receiving the message indicating the first reference signal configuration parameter.
[0104] In some implementations, the wireless communications system 100 may support techniques for performing handover procedures for PCells using L2 signaling. In particular, the wireless communications system 100 may support different L2 message structures (e.g., MAC-CE message structures) that enable the respective L2/MAC-CE messages to activate and deactivate PCells, SCells, or both, to enable handover procedures to be performed via L2 signaling.
[0105] For example, a UE 115 of the wireless communications system 100 may receive an L2 message (e.g., MAC-CE) that includes a bitmap corresponding to multiple serving cells, where values of the bitmap (e.g., 0s or 1s) indicate which serving cells are activated and which are deactivated. In this example, the L2 message may also include some indication as to whether each activated serving cell is activated as a PCell or an SCell. For example, the L2 message may include a TRS ID octet for each activated serving cell, where each TRS ID includes a bit field that indicates whether the respective serving cell is to be activated as a PCell or an SCell. As such, the L2 message may signal for the UE 115 to deactivate the current PCell and to activate a new PCell in order to perform a handover procedure between the respective PCells.
Note: Here, as L2 messaging is being used, the bitmap indicates if the SCell is deactivated before it reaches the UE (refer to Figure 2).
Regarding Claim 4,
Shehata discloses: The method of claim 1, wherein the message indicating the first reference signal configuration parameter comprises: a first field, associated with the SCell, set to a first value indicating activation of the SCell
[0128] The L2 message format 300 may include a bitmap 305 including a set of bit fields (C.sub.n bit fields) corresponding to a set of serving cells that may be activated/deactivated at a UE 115. In this regard, the bitmap 305 includes bit fields corresponding to 31 different serving cells (e.g., C.sub.1-C.sub.31). The bitmap 305 may span a set of octets of the L2 message format 300 (e.g., Octets 1-5). Octets 1-4 of the L2 message format 300 may be referred to as “Step 1” when activating and deactivating respective serving cells with serving cell ID i between 1 and 31.
[0129] In some aspects, the C.sub.n bit fields of the bitmap 305 may include binary bits, where a bit field value of “0” refers to a deactivated serving cell index, and a bit field value of “1” refers to an activated serving cell index. For example, the C.sub.1 bit field may correspond to a first serving cell, and the C.sub.2 bit field may correspond to a second serving cell. In this example, if C.sub.1=1 and C.sub.2=0, this may indicate that the first serving cell is (or is expected to be) activated, where the second serving cell is (or is expected to be) deactivated. As such, different values of the bit fields within the bitmap 305 may be used to activate and deactivate different serving cells at the UE 115.
and a second field comprising an SCell activation reference signal configuration index indicating the first reference signal configuration parameter.
[0124] The UE 115-a may communicate with the second serving cell 205-b as a PCell or an SCell, as indicated by the L2 control signaling 220. In particular, the UE 115-a may communicate with the second serving cell 205-b in accordance with a set of parameters (e.g., SCellActivationRS-Config, PCellActivationRS-Config) indicated by the L3 control signaling 215 and/or the L2 control signaling 220.
[0129] In some aspects, the C.sub.n bit fields of the bitmap 305 may include binary bits, where a bit field value of “0” refers to a deactivated serving cell index, and a bit field value of “1” refers to an activated serving cell index. For example, the C.sub.1 bit field may correspond to a first serving cell, and the C.sub.2 bit field may correspond to a second serving cell. In this example, if C.sub.1=1 and C.sub.2=0, this may indicate that the first serving cell is (or is expected to be) activated, where the second serving cell is (or is expected to be) deactivated. As such, different values of the bit fields within the bitmap 305 may be used to activate and deactivate different serving cells at the UE 115.
Note: Since there are two fields that demarcate when a cell is active or not, the L2 communications provides the parameters in question (paragraph [124]) which correspond to the bitmap values present in paragraph [0129].
Regarding Claim 5,
Shehata discloses: The method of claim 1, wherein the one or more reference signals comprise one or more aperiodic channel state information reference signals (CSI-RSs).
[0167] The UE 115-b may be configured to transmit measurement reports periodically, aperiodically, dynamically, or any combination thereof. For example, in some cases, the UE 11-b may receive an indication of a set of resources usable by the UE 115-b for transmitting measurement reports in accordance with an indicated periodicity. Additionally, or alternatively, the UE 115-b may transmit the measurement report in response to a request or other trigger received from the first serving cell 805-a. Moreover, in other cases, the UE 115-b may transmit the measurement report when certain conditions are met, such as when the UE 115-b identifies another serving cell 805 that exhibits a threshold quality or performance of wireless communications.
Regarding Claim 9,
Claim 9 is rejected on the same grounds of rejection set forth in claim 1.
Shehata discloses: A method comprising: sending, by a base station, one or more messages indicating: one or more reference signal configuration parameters for activation of a secondary cell (SCell); and a unified transmission configuration indicator (TCI) state reference parameter indicating a reference bandwidth part (BWP) of a reference cell
[0115] For example, in some implementations, the L3 control signaling 215 (e.g., RRC message) may include a set of information elements associated with a set of candidate SCell configurations (e.g., SCellActivationRS-Config), a set of candidate PCell configurations (e.g., PCellActivationRS-Config), or both, that may be used for communications with SCells and PCells, respectively. The respective SCell and PCell configurations may each be associated with corresponding SCell identifiers (e.g., SCellActivationRS-Ids) and PCell identifiers (e.g., PCellActivationRS-Ids), respectively. In some aspects, SCell and PCell identifiers may be indicated via tracking reference signal (TRS) identifiers (TRS IDs), as will be described in further detail herein.
[0117] By way of another example, each SCell configuration and/or PCell configuration may include QCL information (e.g., gel-Info), which may include a list of references to TCI states for providing the QCL source and QCL type for each NZP-CSI-RS-Resource listed in NZP-CSI-RS-Resources of the NZP-CSI-RS-ResourceSet indicated by resourceSet. Each TCI-StateId may refer to the TCI-State which has this value for tci-StateId and is defined in tci-StatesToAddModList in the PDSCH-Config included in the BWP-Downlink of the respective serving cell indicated by firstActiveDownlinkBWP-Id in the ServingCellConfig in which the respective information element is included. In some implementations, a first entry in qcl-info may correspond to first entry in nzp-CSI-RS-Resources of that NZP-CSI-RS-ResourceSet.
Note: The “configuration parameters” are found in Applicant’s specification Figures 19B, where this reference has these parameters in paragraph [0115]. As for the “TCI state reference parameter indicating a reference BWP of a reference cell”, Applicant’s specification Figure 19C has these parameters, to which paragraph [0117] contains this information, particularly located in the PDSCH-config information.
sending a message indicating a first reference signal configuration parameter, of the one or more reference signal configuration parameters, wherein the first reference signal configuration parameter comprises: a TCI state index indicating a first TCI state in the reference BWP of the reference cell; and

The respective SCell and PCell configurations may each be associated with corresponding SCell identifiers (e.g., SCellActivationRS-Ids) and PCell identifiers (e.g., PCellActivationRS-Ids), respectively. In some aspects, SCell and PCell identifiers may be indicated via tracking reference signal (TRS) identifiers (TRS IDs), as will be described in further detail herein.

Each TCI-StateId may refer to the TCI-State which has this value for tci-StateId and is defined in tci-StatesToAddModList in the PDSCH-Config included in the BWP-Downlink of the respective serving cell indicated by firstActiveDownlinkBWP-Id in the ServingCellConfig in which the respective information element is included. In some implementations, a first entry in qcl-info may correspond to first entry in nzp-CSI-RS-Resources of that NZP-CSI-RS-ResourceSet.
Note: Paragraph [0442] of Applicant’s specification states that “The TCI state index/identifier (or the TCI state) may be defined either in tci-StatesToAddModList or dl-OrJointTCI-StateList in one or more PDSCH configuration parameters (e.g., PDSCH-Config in FIG. 19C) included in the downlink BWP (e.g., the BWP-Downlink) of the cell.” Here, paragraph [0117] provides this parameter.
a resource set index indicating one or more reference signals; and
[0117] By way of another example, each SCell configuration and/or PCell configuration may include QCL information (e.g., gel-Info), which may include a list of references to TCI states for providing the QCL source and QCL type for each NZP-CSI-RS-Resource listed in NZP-CSI-RS-Resources of the NZP-CSI-RS-ResourceSet indicated by resourceSet.

In this regard, the L1 measurement report may be used by the first serving cell 805-a to evaluate a relative quality of wireless communications between the UE 115-b and other serving cells 805, and to determine whether to trigger handover procedures to other serving cells 805.
Regarding Claim 17,
Claim 17 is rejected on the same grounds of rejection set forth in claim 5.
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 6, 10, and 18 are rejected under 35 U.S.C. § 103 as being unpatentable over Shehata in view of Yuan et. al. (U.S. Pat. Pub. 2024/0275458), herein referred to as “Yuan”.
Regarding Claim 6,
Shehata does not explicitly disclose all the limitations of Claim 6.
However, Yuan discloses: The method of claim 1, further comprising sending a CSI report comprising one or more radio link qualities of the one or more reference signals.
[0085] FIG. 6 is a diagram 600 illustrating a beam switch procedure. As illustrated in FIG. 6, a UE 602 may transmit a CSI report 601 to the base station 604. For monitoring active link performances, the UE 602 may perform measurements of at least one signal, e.g., reference signals, of one or more beams. The measurements may include deriving a metric similar to a Signal to Interference plus Noise Ratio (SINR) for the signal, or RSRP strength or block error rate (BLER) of a reference control channel, e.g., based on an RRC configuration. The reference signal may comprise any of CSI-RS, Physical Broadcast Channel (PBCH), a synchronization signal, or other reference signals for time and/or frequency tracking, etc. In some cases, the UE may determine a configured metric such as block error rate (BLER) for a reference signal for the one or more beams. The measurement(s) may indicate the UE's ability to exchange communication with the base station 604 using the beam. In some aspects, the measurements may indicate that a current beam has a lower quality than a different beam. The UE 602 may indicate the new beam to the base station 604. For example, the CSI report 601 may include a field representing a UE preferred that is different than a current beam. For example, the field representing the UE preferred beam may be a beam index. Based on the CSI report 601, the UE 602 and the base station 604 may perform beam switching, for downlink channels 605 and uplink channels 607. In some aspects, the base station 604 may also generate and transmit a beam indication 603. In some other aspects, the base station 604 may not transmit a beam indication 603. The beam switch performed for the downlink channels 605 and the uplink channels 607 may be independent of the beam indication 603.
Shehata and Yuan are considered to be analogous because they pertain to wireless communications. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Shehata to include the concept of sending a CSI report that contains radio link qualities of the reference signals as taught by Yuan so as to enhance communications in the wireless network.
Regarding Claim 10,
Claim 10 is rejected on the same grounds of rejection set forth in claim 6.
Regarding Claim 18,
Claim 18 is rejected on the same grounds of rejection set forth in claim 6.
Claims 7, 14, and 19 are rejected under 35 U.S.C. § 103 as being unpatentable over Shehata in view of Li et. al. (U.S. Pat. Pub. 2025/0193916), herein referred to as “Li”.
Regarding Claim 7,
Shehata does not explicitly disclose all the limitations of Claim 7.
However, Li discloses: The method of claim 1, further comprising: determining, based on the first TCI state, a spatial domain receiving filter corresponding to the one or more reference signals, wherein the receiving the one or more reference signals comprises using the spatial domain receiving filter.
[0092] In further aspects, this disclosure provides for a RAN node or gNB 802 to indicate to a UE 804 a set of one or more TCI-state IDs that are associated with the configured CSI-RS resource set. That is, recall that above it was described that the RAN node or gNB 802 may indicate to the UE which Rx spatial filters to utilize by sending static, semi-static, or dynamic signaling to indicate a set of TCI-state IDs that are associated with a set of Rx spatial filters. As an extension of this concept, those indicated TCI-state IDs may be associated with a portion of the CSI-RS resource set. Thus, the UE can also treat these indicated TCI-state IDs as an indication of which RSRPs or SINRs the CSI report 822 should carry.
[0093] In some examples, where the UE reports the RSRPs or SINRs for every CSI-RS resource within the configured CSI-RS resource set, the gNB 802 may not need to indicate any particular CSI-RS/TCI-state IDs as gNB order commands. That is, when the UE reports for every spatial Rx filter, the gNB 802 may omit any signaling indicating a subset of Rx spatial filters to report.
Shehata and Li are considered to be analogous because they pertain to wireless communications. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Shehata to include the concept of determining a spatial domain receiving filter based on the TCI state as taught by Li so as to enhance communications in the wireless network.
Regarding Claim 14,
Claim 14 is rejected on the same grounds of rejection set forth in claim 7.
Regarding Claim 19,
Claim 19 is rejected on the same grounds of rejection set forth in claim 7.
Claims 8, 15, and 20 are rejected under 35 U.S.C. § 103 as being unpatentable over Shehata in view of Zhou et. al. (U.S. Pat. Pub. 2022/0104302), herein referred to as “Zhou”.
Regarding Claim 8,
Shehata does not explicitly disclose all the limitations of Claim 8.
However, Zhou discloses: The method of claim 1, further comprising:
determining, based on the message indicating the first reference signal configuration parameter further indicating that the first active downlink BWP of the SCell is associated with two different control resource set (CORESET) pool indexes, a second reference signal configuration parameter, of the one or more reference signal configuration parameters, comprising:
[0086] Accordingly, a UE may be configured for a carrier (e.g., an individual CC, bandwidth part (BWP), and the like) associated with Pcell/Pscell/Scell that is configured with the first CORESET pool index value (e.g., CORESETPoolIndex=0) and a second CORESET pool index value (e.g., CORESETPoolIndex=1). The first CORESET pool index value may be associated with the first TRP 704a of Pcell/Pscell/Scell and the second CORESET pool index value may be associated with the second TRP 704b of Pcell/Pscell/Scell. Each TRP 704 may transmit one or more BFD reference signals that are associated with their respective value of CORESET pool index. This may include two sets of BFD reference signals (e.g., failureDetectionResources) being configured, with each set corresponding to a different value of CORESET pool index. In another example this may include each reference signal (e.g., each resource within failureDetectionResources) being configured with a CORESET pool index value. If the resource is not configured with a CORESET pool index value, it may be considered associated with CORESET pool index value 0 (e.g., the first CORESET pool index value). Additionally, a resource may be configured with both values of CORESET pool indices. When the reference signals (e.g., failureDetectionResources) are not configured, the reference signal sets indicated in the active transmission configuration indicator (TCI) states of CORESETS configured with CORESET pool index value=0/1 (e.g., either CORESET pool index value) may determine the first/second set of resources, respectively. BFD for a value of CORESET pool index may be declared when the radio link quality is worse than Qout for all the reference signals and the BFD resources that are associated with that CORESET pool index value.
Note: “failureDetectionResources” is being broadly interpreted as the reference signal applied over the different CORESET pool indexes as stated above.
a second TCI state index indicating a second TCI state in the reference BWP of the reference cell; and
[0086] Accordingly, a UE may be configured for a carrier (e.g., an individual CC, bandwidth part (BWP), and the like) associated with Pcell/Pscell/Scell that is configured with the first CORESET pool index value (e.g., CORESETPoolIndex=0) and a second CORESET pool index value (e.g., CORESETPoolIndex=1). The first CORESET pool index value may be associated with the first TRP 704a of Pcell/Pscell/Scell and the second CORESET pool index value may be associated with the second TRP 704b of Pcell/Pscell/Scell. Each TRP 704 may transmit one or more BFD reference signals that are associated with their respective value of CORESET pool index. This may include two sets of BFD reference signals (e.g., failureDetectionResources) being configured, with each set corresponding to a different value of CORESET pool index. In another example this may include each reference signal (e.g., each resource within failureDetectionResources) being configured with a CORESET pool index value. If the resource is not configured with a CORESET pool index value, it may be considered associated with CORESET pool index value 0 (e.g., the first CORESET pool index value). Additionally, a resource may be configured with both values of CORESET pool indices. When the reference signals (e.g., failureDetectionResources) are not configured, the reference signal sets indicated in the active transmission configuration indicator (TCI) states of CORESETS configured with CORESET pool index value=0/1 (e.g., either CORESET pool index value) may determine the first/second set of resources, respectively. BFD for a value of CORESET pool index may be declared when the radio link quality is worse than Qout for all the reference signals and the BFD resources that are associated with that CORESET pool index value.
Note: The “second TCI state index” is also configured with a CORESET pool index value, thereby having a second TCI state index if the CORESET index is 1.
a second resource set index indicating one or more second reference signals; and
[0086] Accordingly, a UE may be configured for a carrier (e.g., an individual CC, bandwidth part (BWP), and the like) associated with Pcell/Pscell/Scell that is configured with the first CORESET pool index value (e.g., CORESETPoolIndex=0) and a second CORESET pool index value (e.g., CORESETPoolIndex=1).

BFD for a value of CORESET pool index may be declared when the radio link quality is worse than Qout for all the reference signals and the BFD resources that are associated with that CORESET pool index value.
Note: Since the BFD resources are also tied into a CORESET pool index value, then this would also be indexed along with the CORESET pool index value.
