Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a layer one reference signal received power (L1-RSRP) measurement report to include an indication of L1-RSRP measurements associated with one or more synchronization signal bocks (SSBs) included in an SSB set, wherein the SSB set is identified, from a plurality of SSB sets, in the L1-RSRP measurement report by an SSB set indicator, and wherein the one or more SSBs are identified in the L1-RSRP measurement report by respective SSB indexes that index into the SSB set. The UE may transmit the L1-RSRP measurement report. Numerous other aspects are provided.

Abstract: A phase tracking reference signal (PT-RS) may be transmitted to enable a receiver to correct phase noise in wireless communication. A UE scheduled for one PDSCH with DMRS ports in two or more DMRS CDM groups that are associated with two TCI states may be configured for PT-RS using two PT-RS ports. Therefore, rather than limiting PT-RS to a single port, the PT-RS may be transmitted to the UE using two PT-RS ports. The apparatus transmits a capability indication for more than one PT-RS port for receiving a downlink shared channel based on a first TCI and a second TCI. The apparatus receives a configuration for a maximum number of downlink PT-RS ports from a base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may detect, for physical downlink shared channel transmissions in a multi-panel frequency division multiplexing deployment with multi-user, multiple input, multiple output transmission, a semi-persistent scheduling occasion update event. The BS may switch from performing semi-persistent scheduling for the physical downlink shared channel transmissions on a first subband to performing semi-persistent scheduling for the physical downlink shared channel transmissions on a second subband. Numerous other aspects are provided.

Abstract: Aspects relate to implementing multiplexing with a single carrier waveform. In some examples, a total bandwidth may be divided into a plurality of bandwidth parts (BWPs), each including a plurality of tones. Each of the BWPs may further be divided into two or more interlaces, where each interlace includes a respective number of interleaved tones. A base station may assign each of a plurality of UEs a respective set of one or more interlaces within at least one BWP for multiplexing communication with the base station.

Abstract: Aspects directed towards communications for random access procedures are disclosed. In one example, a first beam and a second beam may be available for communications between a scheduled entity and a scheduling entity. The scheduling entity may send, and the scheduled entity may receive, a message 1 transmission for a random access procedure on the first beam. The scheduled entity may open a random access response (RAR) window to monitor for a message 2 transmission according to a predetermined sequence designating whether to monitor the first beam, the second beam, or some combination thereof. The scheduling entity may send, and the scheduled entity may receive, the message 2 transmission on the first beam or the second beam as designated by the predetermined sequence. Other aspects, embodiments, and features are also included.

Abstract: A configuration is disclosed to enable a UE to determine and/or prepare Rx beams prior to downlink reception in multi-TRP operation. The apparatus sends, to a first TRP, a report indicating a plurality of threshold scheduled offsets. Each threshold scheduled offset associated with a different number of TCI states. The apparatus receives, from the first TRP, DCI including a TCI and a time-offset. The TCI comprising at least one TCI state. Each TCI state indicating a Tx beam for a TRP of a set of TRPs. The set of TRPs including the first TRP. The apparatus determines at least one Rx beam based on at least one of the received TCI, the time-offset, or one or more of the plurality of threshold scheduled offsets. The apparatus receives, based on the received time-offset, a PDSCH from each TRP of the set of TRPs through the determined at least one Rx beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may perform a listen-before-talk (LBT) procedure with a directional coverage that is based at least in part on a directional coverage of a set of synchronization signal and physical broadcast channel (PBCH) blocks (SSBs) of a synchronization signal (SS) burst set to be transmitted by the base station. The first wireless node may transmit, to one or more second wireless nodes, the set of SSBs based at least in part on a successful result of the LBT procedure. Numerous other aspects are provided.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for wireless communication are provided. The apparatus may be a base station. The apparatus may transmit an uplink grant to a UE during a first transmit opportunity. The apparatus may signal, during a second transmit opportunity, a grant trigger to the UE to trigger operations associated with the uplink grant that are uncompleted after the first transmit opportunity. The grant trigger may be associated with a set of UEs that includes the UE. The set of UEs may be a subset of the UEs having pending transmissions. The apparatus may instruct the UE regarding whether to keep or discard resources granted by the uplink grant when the UE switches to a different beam during or prior to the second transmit opportunity.
