Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a particular control resource set (CORESET), downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH). The UE may be configured with multi-DCI based multi-transmission/reception point (TRP) operation. The UE may determine, based at least in part on the UE being configured with multi-DCI based multi-TRP operation, a fixed higher layer index that identifies a CORESET group with which the particular CORESET is associated. The UE may perform an operation, associated with receiving the PDSCH or transmitting the PUSCH, based at least in part on the fixed higher layer index identifying the CORESET group with which the particular CORESET is associated. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method determines resources to monitor for beam failure detection (BFD) when the UE is in a mode of operation involving at least first and second transmitter receiver points (TRPs). The method then detects a beam failure based on monitoring of the determined resources. The method further triggers a beam failure recovery (BFR) procedure based on the detection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive, from a user equipment (UE), a message that indicates whether the UE received a downlink transmission from the base station in a first frequency range. The base station may schedule one or more reference signal (RS) transmissions in the first frequency range and one or more RS transmissions in a second frequency range based at least in part on the message received from the UE, and reschedule the downlink transmission on a component carrier in either the first frequency range or the second frequency range based at least in part on channel quality information that is determined from the one or more RS transmissions in the first frequency range and the one or more RS transmissions in the second frequency range. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatuses for the identification of a channel state information reference signal (CSI-RS) resource. In some aspects, a UE that receives the CSI-RS may determine CSI feedback based at least in part on the CSI-RS after detecting the CSI-RS resource that includes the CSI-RS. Signaling or techniques for when no CSI-RS is detected (such as when the base station fails a channel access operation for all available CSI-RS resources) are also provided. Furthermore, approaches for rate matching for a shared channel around CSI-RS resources or for CSI interference management (CSI-IM) resources are provided, as well as CSI reporting approaches for cases when the UE fails to transmit CSI feedback due to a failed channel access operation, such as a triggered or re-triggered CSI report.

Abstract: Aspects described herein relate to resource block allocation for time domain single-carrier waveform processing in new radio (NR). Specifically, in an aspect, a guard band may be allocated for a single-carrier waveform in a time or frequency domain. In another aspect, a resource block may be allocated for a time domain single-carrier waveform.

Abstract: This disclosure provides systems, methods and apparatuses for listen-before-talk (LBT) failure-based channel congestion measurement and recovery triggering. In one aspect, a user equipment (UE) may determine an LBT metric based on a result of attempting to perform an uplink transmission in connection with an LBT procedure. For example, the UE may determine an absolute quantity of LBT failures, a ratio of unsuccessful uplink transmissions to total uplink transmission attempts, an absolute quantity of LBT successes, or another type of LBT metric. The UE may trigger a recovery action, such as a radio link failure (RLF) recovery action or a bandwidth part switch, based on determining that the LBT metric satisfies a threshold.

Abstract: This disclosure provides systems, methods and apparatuses for uplink channel transmission for multiple transmit receive points (TRPs). In one aspect, a user equipment (UE) resolves overlapping physical uplink control channels (PUCCHs) in a slot or overlapping PUCCH(s) and PUSCH(s) that are mapped to a same TRP in a multi-TRP scenario and that are mapped to two or more different TRPs in the multi-TRP scenario. For example, in a multi-TRP scenario that includes two TRPs, the UE may eliminate overlap of these uplink channels for each of the two TRPs individually and may additionally eliminate overlap of these uplink channels between the two TRPs.

Abstract: Aspects described herein relate to receiving multiple synchronization signal blocks (SSBs) from a target cell over a measurement time window. A repeating beam index for one or more of the multiple SSBs can be identified based at least in part on a determination of a repeat parameter indicating a number of beams in a SSB pattern for the target cell. A beam set of the one or more of the multiple SSBs determined to have the same repeating beam index can be associated. One or more parameters of the one or more of the multiple SSBs of the beam set can be measured and reported.
