Abstract: A UE may receive a configuration of multiple TCI states including a TCI state for each of multiple TRPs. The UE may also receive an indication of dormancy for one or more TRP of the multiple TRPs. The UE may further transmit or receive communication based on a default TCI state, the default TCI based at least in part on the dormancy of the TRP. The UE may communicate with a network entity that configures multiple TCI states for the UE. The multiple TCI states may include a TCI state for each of multiple TRPs. The network entity may output for transmission an indication of dormancy for one or more TRP of the multiple TRPs. The network entity may further output or obtain communication based on a default TCI state, the default TCI based at least in part on the dormancy of the TRP.

Abstract: A victim user equipment (UE) may experience cross-link interference (CLI) from a physical uplink shared channel (PUSCH) transmission from an aggressor UE or self-interference (SI) from a PUSCH transmission from a transmitter of the victim UE. The present disclosure provides for configuration of measurement resources and a CLI report for mitigation of CLI. A base station may transmit a configuration of the measurement resources including channel state information interference measurement (CSI-IM) resources and a configuration of a CLI report. The CSI-IM resources match PUSCH symbols or demodulation reference signal (DMRS) symbols of an aggressor UE. The victim UE measures a CLI or a SI on the CSI-IM resources. The victim UE reports the CLI or the SI to the base station according to the configuration of the CLI report. The base station may schedule transmissions to mitigate the CLI or the SI.

Abstract: In some scenarios, SRS transmission over the full SRS bandwidth may be unnecessary and/or inefficient. Therefore, a need exists for approaches to SRS transmission over less than the full SRS bandwidth. Described herein are techniques and solutions of SRS transmission using only a portion of the full SRS bandwidth, or a partial SRS bandwidth. The present disclosure provides for SRS transmission using a partial SRS bandwidth through sounding patterns that use only the partial SRS bandwidth and/or using a partial SRS bandwidth through various SRS sequence generation configured for the partial SRS bandwidth. An apparatus receives an SRS configuration indicating a full SRS bandwidth; determines a frequency hopping pattern for SRS transmission based on the SRS configuration, and the frequency hopping pattern is limited to a partial SRS bandwidth less than the full SRS bandwidth; and transmits the SRS transmission to the base station based on the frequency hopping pattern.

Abstract: Aspects relate to wireless communication using multiple active bandwidth parts (BWPs). For example, a base station may configure a user equipment with two or more active BWPs. The user equipment may then use one or more of the active BWPS at a time. For example, the user equipment may use multiple active BWPs for full-duplex communication. Alternatively or in addition, the user equipment may switch between active BWPs taking advantage of the extremely low switching time (e.g., at or near zero seconds) between active BWPs.

Abstract: Aspects for time bundling an SRS resource over a plurality of instances are disclosed. The apparatus may include a user equipment (UE). The user equipment may receive a configuration from a base station for time-bundling at least one sounding reference signal (SRS) resource. The time-bundling may be performed by the UE transmitting a plurality of SRS signals at different times using an identical center frequency and at least two different frequency resource allocations. The UE may transmit the plurality of SRS signals based on the configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a physical downlink shared channel (PDSCH) transmission in one or more of a half-duplexing mode or a full-duplexing mode. The UE may attempt to decode the PDSCH transmission using a low-density parity-check (LDPC) decoder. The UE may transmit, to the base station, feedback that indicates a difference between a half-duplex channel quality and a full-duplex channel quality based at least in part on one or more decoding parameters associated with the LDPC decoder. Numerous other aspects are described.
