Conclusion
The prior art made of record and considered pertinent to applicant's disclosure and Claims:
WEI (US 20220321189 A1)
Abstract: A user equipment (UE) may report capabilities pertaining to UE feedback processing, such as a number of simultaneous feedback reports that can be processed and reported by the UE for various types of feedback. UE feedback processing capability may depend on channel state information (CSI) processing units (CPUs) available to the UE for feedback processing operations (for performing channel measurements, processing feedback, generating a feedback report, etc.). A UE may report feedback processing capability separately for periodic feedback reporting and for aperiodic feedback reporting, for different types of feedback reporting (for CSI reporting, for beam management reporting, etc.), etc. As such, a UE may more efficiently report capabilities pertaining to UE feedback processing, and a base station may more efficiently configure UE feedback reporting according to UE feedback processing capability.
Onggosanusi (US 20210022026 A1)
[0125] illustrated in diagram 500 of FIG. 5 wherein a UE is configured for measuring/receiving aperiodic CSI-RS (AP-CSI-RS) and reporting aperiodic CSI (AP CSI), a DL multi-beam operation starts with the gNB/NW signaling to a UE an aperiodic CSI-RS (AP-CSI-RS) trigger or indication (step 501). This trigger or indication can be included in a DCI (either UL-related or DL-related, either separately or jointly signaled with an aperiodic CSI request/trigger) and indicate transmission of AP-CSI-RS in a same (zero time offset) or later slot/sub-frame (>0 time offset). Upon receiving the AP-CSI-RS transmitted by the gNB/NW (step 502), the UE measures the AP-CSI-RS and, in turn, calculates and reports a “beam metric” (included in the CSI, indicating quality of a particular TX beam hypothesis) (step 503). Examples of such beam reporting (supported in Rel.15/16 NR) are CSI-RS resource indicator (CRI) or SSB resource indicator (SSB-RI) coupled with its associated L1-RSRP and/or L1-SINR. Upon receiving the beam report from the UE, the NW/gNB can use the beam report to select a DL TX beam for the UE and indicate the DL TX beam selection (step 504) using the TCI field in the DL-related DCI (that carries the DL assignment, such as DCI format 1_1 in NR). The TCI state corresponds to a reference RS (in this case, an AP-CSI-RS) defined/configured via the TCI state definition (higher-layer/RRC configured, from which a subset is activated via MAC CE for the DCI-based selection). Upon successfully decoding the DL-related DCI with the TCI field, the UE performs DL reception (such as data transmission on PDSCH) with the DL TX beam associated with the TCI field (step 505). In this example embodiment, only one DL TX beam is indicated to the UE.
[0126], the term “Resource Indicator”, also abbreviated as REI, is used to refer to an indicator of RS resource used for signal/channel and/or interference measurement. This term is used for illustrative purposes and hence can be substituted with any other term that refers to the same function. Examples of REI include the aforementioned CSI-RS resource indicator (CRI) and SSB resource indicator (SSB-RI). Any other RS can also be used for signal/channel and/or interference measurement such as DMRS.
[0130] - [0131]
[0134] The core features pertaining to UE-initiated/triggered reporting are steps 602 (along with 603) and 606 in flowchart 600. In 602 and 603, UE-k initiates the beam reporting instead of waiting for the gNB/NW to request the report. Step 606 is basically the recurrence of 602 wherein UE-k keeps monitoring and measuring the pertinent measurement RS. Whether or not the UE can initiate/trigger AP beam/CSI reporting can solely be up to the UE, or it can also be configured/indicated by the gNB/NW (e.g. via higher layer or dynamic MAC CE or/and DCI signaling). Or, optionally, it is based on the K.sub.k value. For instance, if K.sub.k>t, a certain threshold, then the UE can initiate/trigger beam/CSI reporting.
[0139]
[0145] Optionally, the NW/gNB can signal the set of reserved resources dynamically via L1 and/or L2 DL control (PDCCH and/or MAC CE). These resources will be used for transmitting the AP beam/CSI report. In addition, UE-k is also configured with at least one measurement RS resource such as CSI-RS (NZP and/or ZP CSI-RS), SSB, or other RS types such as SRS (e.g. if beam correspondence holds). The measurement RSs are utilized to measure channel and/or beam quality such as CSI and/or beam metric. In addition, any of the measurement RSs can serve as a reference RS for beam indication (e.g. representing a TCI state). The beam metric can represent link quality associated with data (PDSCH) and/or dedicated control (PDCCH). Examples of such metric include L1-RSRP, L1-SINR, CQI, or hypothetical BLER, possibly accompanied with at least one measurement RS resource index/indicator.

Tooher (US 20190074953 A1)
[0005] A wireless transmit/receive unit (WTRU) may comprise a memory, a processor, and/or a transceiver. The processor may be configured with one or more Channel State Information (CSI) Processes. The processor may be configured with one or more feedback resources. The processor may be configured to determine at least one of: a ranking of the one or more CSI Processes, and/or an occurrence of a condition of use of at least one of the one or more feedback resources. The processor may be configured to map a number of the one or more CSI Processes to the at least one of the one or more feedback resources based on at least one of: the ranking of the one or more CSI Processes, and/or the occurrence of the condition of use of the at least one of the one or more feedback resources. The processor may be configured to initiate a feedback report of at least one of the one or more CSI Processes. The transceiver may be configured to send the feedback report of the at least one CSI Process of the one or more CSI Processes using a mapped feedback resource of the one or more feedback resources.
[0062] [0064]- [0067]
[0070] In WTRU-centric transmission, a (e.g. one or more, or each) WTRU may be served by a set of transmission and/or reception points where the set may be WTRU-specific. A transmission point set may be adapted dynamically without requiring (e.g. some amount and/or a large amount of) reconfiguration signaling. Stated somewhat differently, the techniques described herein may provide for an (e.g. optimal) set of transmission points per WTRU to be adapted dynamically and/or maintained without requiring what may be perhaps large amounts of configuration and/or reconfiguration signaling. The described techniques may provide for an elimination and/or reduction in configuration and/or reconfiguration reference signals (e.g. for measurement reporting and/or for demodulation). The described techniques may provide for an elimination and/or reduction in reconfiguring of CSI reporting, for example to support multiple transmission hypotheses.
[0106]- [0116]
[0117] A feedback resource may have a condition of use. A WTRU may determine from one or more conditions of use for one or more feedback resources the appropriate CSI Process measurements to report using one or more feedback resources. For example, a WTRU may be configured with one or more, or two CSI Processes and/or a single feedback resource. The feedback resource may have a condition that the WTRU may report measurements for the CSI Process with highest CQI. A WTRU may provide a CSI Process ID in the feedback report. For example, a new (e.g., fresh and/or previously unused) flag may be provided, e.g., when reporting a reporting type (e.g. RI). An eNB may know from the presence of the new flag that the report includes a CSI Process ID, the reporting type (e.g. RI) and/or other specified content associated with a new flag. A report may provide an indication about which condition(s) was/were met for the CSI Process to have been chosen for a feedback resource. FIG. 5 is an example of a WTRU configured with a (e.g. single) set of feedback resources for a subset of CSI Processes. The WTRU may select the appropriate CSI Process' feedback reports for one or more, or each, feedback instance, perhaps for example based on one or more measurement criteria.
