Abstract: A configuration for a wireless device to perform iterations of SIM to detect clutter echo in order to improve a configuration for SIM. The apparatus performs a SIM for multiple beam pairs based on a first transmission power. The apparatus performs an iteration of the SIM for one or more beam pairs that meet a criteria. The iteration of the SIM is based on a second transmission power. The second transmission power is greater than the first transmission power.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node (e.g., a user equipment) may determine one or more measurements associated with a beam search performed during a downlink beam management process. The first wireless node may transmit, to a second wireless node (e.g., a base station), a report that indicates one or more candidate downlink receive beams, candidate uplink transmit beams, or candidate downlink receive and uplink transmit beam pairs suitable for full-duplex operation based at least in part on the one or more measurements. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a channel measurement (CM) process indicating at least one channel measurement resource (CMR) associated with quasi co-location (QCL) information, wherein the QCL information corresponds to a transmit (Tx) beam of the base station associated with a receive (Rx) beam of the UE; receive a configuration for an interference measurement (IM) process indicating at least one interference measurement resource (IMR) associated with a UE beam pair comprising the Rx beam of the UE and a Tx beam of the UE; perform a self-interference measurement (SIM), wherein the SIM procedure is based at least in part on the CM process and the IM process; and transmit, to the base station, a measurement report based at least in part on the SIM procedure. Numerous other aspects are provided.

Abstract: The present disclosure provides for a configuration that enables an apparatus to determine beam pairs for full duplex communication based on a cross-link interference procedure. The apparatus determines a subset of receive beams based on a beam measurement process, where each receive beam is associated with a different antenna array panel. In some aspects, the apparatus performs a channel measurement process based on the subset of receive beams. The apparatus sweeps through transmitted sounding reference signals from a same transmit beam corresponding to each receive beam of an antenna array panel and receives the transmitted sounding reference signals incrementally through other receive beams associated with other antenna array panels. The apparatus measures a self-interference for at least one beam pair of the subset of receive beams based on a received sounding reference signal. The apparatus selects one or more beam pairs based on a self-interference measurement or a signal-to-interference-plus-noise ratio.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a user equipment (UE). The method generally includes determining whether a plurality of beam configurations configured for processing one or more downlink (DL) signals are different than a first beam configuration for processing at least one CSI-RS, the one or more DL signals to be received in the same symbol as the at least one CSI-RS; selecting a second beam configuration for processing the at least one CSI-RS based on the determination; receiving the at least one CSI-RS; and processing the at least one CSI-RS based on the selected second beam configuration.

Abstract: This disclosure provides methods, devices and systems for handling a reception when another scheduled transmission is canceled. In an aspect, a user equipment (UE) may receive a message from a base station scheduling a first reception for the UE on first resources. The UE may receive a first indicator scheduling a first transmission from the UE on second resources that at least partially overlap with the first resources. The UE may receive a second indicator cancelling the first transmission in a region that partially or fully overlaps the second resources. The UE may determine whether to receive the first reception on the first resources. The UE may transmit an acknowledgment indicating a reception status of the first reception in response to determining to receive the first reception. The base station may determine whether the acknowledgment indicates a reception status of the first reception.

Abstract: Aspects relate to implementing a non-dropping rule for mini-slot based repetition of downlink channel data or control. In one example, cancelled repetition may be identified, non-cancelled remaining repetitions may be received, and acknowledgment feedback based on reception results may be generated. In another example, a plurality of time domain resource allocation (TDRA) candidate occasions may be identified where each occasion occurs within a different respective one of a plurality of mini-slots, each mini-slot carrying a different respective one of a plurality of downlink channel repetitions. A TDRA table may be maintained. The TDRA table may include TDRA entries such as location information of the plurality of TDRA candidate occasions associated with the plurality of downlink channel repetitions. The TDRA table may be maintained when at least one of the plurality of downlink channel repetitions is not decoded. A wireless communication device may refrain from dropping non-decoded downlink channel repetitions.
