An example of K value is 16, 32 or 64. When the UE is configured with “SSBRI/RSRP”, the UE can be requested to report N different SSBRIs and their corresponding L1-RSRP values. The example of N can be 1, 2, 3, and 4 [0136]) and wherein the reporting includes reporting quality information of a first candidate downlink reference signal (In a beam report configured with N>1 reported beams, the UE is requested to report 7-bit L1-RSRP of the CSI-RS resource (CRI) or SSB with the largest L1-RSRP and 4-bit differential RSRP of all other N−1 reported CSI-RS resources (CRI) or SSBs. The differential RSRP is calculated with reference to the largest L1-RSRP reported in the same reporting instance [0222]) of the plurality of candidate downlink reference signals and reporting a difference between the quality information of the first candidate downlink reference signal and corresponding quality information of at least one of the remaining candidate downlink reference signals of the plurality of candidate downlink reference signals (If the higher layer parameter nrofReportedRS is configured to be larger than one, the UE may use largest L1-RSRP and differential L1-RSRP based reporting, where the largest value of L1-RSRP uses a 7-bit value and the differential L1-RSRP uses a 4-bit value. The differential L1-RSRP values are computed with 2 dB step size with a reference to the largest L1-RSRP value which is part of the same L1-RSRP reporting instance [0222]-[0226]).
Therefore, it would have been obvious to one of ordinary skill in art before the effective filing date of the claimed invention to modify Matsumura by specifically wherein the candidate downlink reference signal comprises a plurality of candidate downlink reference signals and wherein the reporting includes reporting quality information of a first candidate downlink reference signal of the plurality of candidate downlink reference signals and reporting a difference between the quality information of the first candidate downlink reference signal and corresponding quality information of at least one of the remaining candidate downlink reference signals of the plurality of candidate downlink reference signals, as taught by Guo for the purpose of providing an effective beam reporting scheme in an advanced wireless communication system [0030].
Regarding claim 15, Matsumura discloses everything claimed as applied above (see claim 9), however Matsumura does not explicitly disclose, wherein the candidate downlink reference signal comprises a plurality of candidate downlink reference signals and wherein the reporting includes reporting quality information of a first candidate downlink reference signal of the plurality of candidate downlink reference signals and reporting a difference between the quality information of the first candidate downlink reference signal and corresponding quality information of at least one of the remaining candidate downlink reference signals of the plurality of candidate downlink reference signals.
In the same field of endeavor, Guo discloses, wherein the candidate downlink reference signal comprises a plurality of candidate downlink reference signals (the UE can be configured with higher layer parameter ReportQuantity set to be “CRI/RSRP” or “SSBRI/RSRP”. When the UE is configured with “CRI/RSRP”, the UE can be requested to report N different CRIs and their corresponding L1-RSRP based one measuring K configured CSI-RS resources. An example of K value is 16, 32 or 64. When the UE is configured with “SSBRI/RSRP”, the UE can be requested to report N different SSBRIs and their corresponding L1-RSRP values. The example of N can be 1, 2, 3, and 4 [0136]) and wherein the reporting includes reporting quality information of a first candidate downlink reference signal (In a beam report configured with N>1 reported beams, the UE is requested to report 7-bit L1-RSRP of the CSI-RS resource (CRI) or SSB with the largest L1-RSRP and 4-bit differential RSRP of all other N−1 reported CSI-RS resources (CRI) or SSBs. The differential RSRP is calculated with reference to the largest L1-RSRP reported in the same reporting instance [0222]) of the plurality of candidate downlink reference signals and reporting a difference between the quality information of the first candidate downlink reference signal and corresponding quality information of at least one of the remaining candidate downlink reference signals of the plurality of candidate downlink reference signals (If the higher layer parameter nrofReportedRS is configured to be larger than one, the UE may use largest L1-RSRP and differential L1-RSRP based reporting, where the largest value of L1-RSRP uses a 7-bit value and the differential L1-RSRP uses a 4-bit value. The differential L1-RSRP values are computed with 2 dB step size with a reference to the largest L1-RSRP value which is part of the same L1-RSRP reporting instance [0222]-[0226]).
Therefore, it would have been obvious to one of ordinary skill in art before the effective filing date of the claimed invention to modify Matsumura by specifically providing wherein the candidate downlink reference signal comprises a plurality of candidate downlink reference signals and wherein the reporting includes reporting quality information of a first candidate downlink reference signal of the plurality of candidate downlink reference signals and reporting a difference between the quality information of the first candidate downlink reference signal and corresponding quality information of at least one of the remaining candidate downlink reference signals of the plurality of candidate downlink reference signals, as taught by Guo for the purpose of providing an effective beam reporting scheme in an advanced wireless communication system [0030].
Claims 21 and 26 are rejected under 35 U.S.C. 103 as being unpatentable over Matsumura, and further in view of Zhao et al. (US 20210013954, hereinafter “Zhao”).
Regarding claim 21, Matsumura discloses everything claimed as applied above (see claim 17), however Matsumura does not explicitly disclose, wherein selecting the downlink reference signal corresponding to the spatial domain transmission filter to be used by the WD for uplink transmissions includes selecting an uplink-downlink beam pair that provides a highest path gain between the network node and the WD.
In the same field of endeavor, Zhao discloses, wherein selecting the downlink reference signal corresponding to the spatial domain transmission filter to be used by the WD for uplink transmissions includes selecting an uplink-downlink beam pair that provides a highest path gain between the network node and the WD (The process of downlink beamforming training is a process of finding an optimal beam pair composed of an optimal transmission beam of the base station and an optimal receiving beam of the user equipment. Similarly, in the uplink, the receiving beams of the base station and the transmission beams of the user equipment also form a set of beam pairs., [0069]-[0072]).
Therefore, it would have been obvious to one of ordinary skill in art before the effective filing date of the claimed invention to modify Matsumura by specifically providing wherein selecting the downlink reference signal corresponding to the spatial domain transmission filter to be used by the WD for uplink transmissions includes selecting an uplink-downlink beam pair that provides a highest path gain between the network node and the WD, as taught by Zhao for the purpose of providing an improved fast beam management, which utilizes a matching status between a channel path parameter under a first beam and a channel path parameter under a second beam covered by the first beam to select a particular second beam [0118].
Regarding claim 26, Matsumura discloses everything claimed as applied above (see claim 22), however Matsumura does not explicitly disclose, wherein selecting the downlink reference signal corresponding to the spatial domain transmission filter to be used by the WD for uplink transmissions includes selecting an uplink-downlink beam pair that provides a highest path gain between the network node and the WD.
In the same field of endeavor, Zhao discloses, wherein selecting the downlink reference signal corresponding to the spatial domain transmission filter to be used by the WD for uplink transmissions includes selecting an uplink-downlink beam pair that provides a highest path gain between the network node and the WD (The process of downlink beamforming training is a process of finding an optimal beam pair composed of an optimal transmission beam of the base station and an optimal receiving beam of the user equipment.
