Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive, from a base station, information indicating resource locations in which one or more synchronization signal blocks (SSBs), of a set of SSBs, are to be transmitted. The mobile station may selectively monitor a plurality of sets of resource element groups (REGs) of physical downlink control channel (PDCCH) repetitions based at least in part on whether at least one SSB, of the one or more SSBs, is to collide with one or more of the plurality of sets of REGs. Numerous other aspects are described.

Abstract: Aspects relate to configuring and managing hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback codebooks for use in wireless communication systems. The HARQ-ACK codebooks include priority-based HARQ-ACK codebooks of differing priorities, such as Type 1 and Type 2 codebooks, and one-shot (Type 3) HARQ-ACK codebooks. In one example, a wireless communication device may be configured to obtain a set of HARQ-ACK codebooks that include priority-based HARQ-ACK codebooks of differing priorities and a separate one-shot HARQ-ACK codebook. The wireless communication device may further be configured to process first and second physical uplink channels based on the priority of the first physical uplink channel and the priority of the second physical uplink channel, where one of the two physical uplink channels includes the one-shot HARQ-ACK codebook, and with the processing performed in combination with the use of the priority-based HARQ-ACK codebooks.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) message that dynamically schedules one or more physical uplink shared channel (PUSCH) transmissions. The UE may autonomously determine a set of scheduling parameters for the one or more PUSCH transmissions that are dynamically scheduled by the DCI message. The UE may transmit the one or more PUSCH transmissions based at least in part on the set of scheduling parameters. Furthermore, in some aspects, uplink control information (UCI) may be multiplexed onto each of the one or more PUSCH transmissions. For example, the UCI multiplexed onto each PUSCH transmission may indicate the set of scheduling parameters autonomously determined for the respective PUSCH transmission. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to a wireless user equipment (UE) establishing and utilizing a reference timing for a carrier or cell with multiple transmission and reception points (TRPs). A UE may receive a downlink signal on each of a plurality of component carriers (CCs), and determine respective timing events (e.g., slot boundaries, subframe boundaries, etc.) corresponding to each of the plurality of CCs. The UE may then determine a reference time for a first CC of the plurality of CCs. This reference time corresponds to a function of two or more timing events corresponding to different TRPs utilizing the first CC. The UE then determines a relative timing difference between the plurality of CCs based on this determined reference time. Other aspects, embodiments, and features are also claimed and described, including determining and utilizing a reference time on an uplink CC.

Abstract: Aspects described herein relate to determining multiple beams to use in transmitting messages in a random access procedure with one or more transmission/reception points (TRPs) of a cell, and transmitting, to the one or more TRPs of the cell, multiple instances of a first random access message based on the multiple beams, where each of the multiple instances of the first random access message include a preamble portion and a payload portion. In another aspect, a node receiving the multiple instances of the first random access message can determine multiple beams to use in transmitting messages in the random access procedure and can transmit with one or multiple TRPs, to the UE and in response to the first random access message, multiple instances of a second random access message based on the multiple beams.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) message that includes a frequency domain resource allocation field to indicate allocated resource blocks (RBs) across multiple transmission configuration indication (TCI) states. The UE may identify, based at least in part on the DCI message and/or a radio resource control configuration, at least one parameter that indicates a unit of contiguous RBs over which the same precoding is used and/or a resource allocation type. The UE may assign the allocated RBs to individual TCI states among the multiple TCI states based at least in part on the unit of contiguous RBs over which the same precoding is used and/or the resource allocation type. Numerous other aspects are provided.
