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: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a modulation and coding scheme (MCS) for an uplink communication of the UE; identify a set of beta values for uplink control information of the uplink communication according to a mapping between the set of beta values and the MCS, wherein the set of beta values is for determination of a number of resource elements or modulation symbols for the uplink control information; and transmit the uplink control information based at least in part on the set of beta values. Numerous other aspects are provided.

Abstract: Techniques and apparatus for using downlink control information (DCI) to avoid hybrid automatic repeat request (HARQ) process identifier (ID) conflicts in scenarios where multiple semi persistently scheduled (SPS) configurations share the same pool of HARQ process IDs are provided. One example technique involves a user equipment (UE) receiving an indication of a plurality of SPS configurations, each SPS configuration allocating the UE with a set of SPS occasions for physical downlink shared channel (PDSCH) transmissions. Information for resolving a conflict between a first HARQ process ID associated with a first SPS occasion of a first of the plurality of SPS configurations and a second HARQ process ID associated with a second SPS occasion of a second of the plurality of SPS configurations is received. The first SPS occasion occurs prior to the second SPS occasion. The conflict is resolved based on the information.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a user equipment (UE) and/or base station. In one aspect, the apparatus may determine a selection procedure for uplink transmissions, the selection procedure including information for uplink data retransmissions. The apparatus may also transmit, to a UE, the selection procedure for uplink transmissions. The apparatus may also monitor for at least one uplink transmission from the UE based on the selection procedure for uplink transmissions. In another aspect, the apparatus may receive, from a base station, a selection procedure for uplink transmissions, the selection procedure including information for uplink data retransmissions. The apparatus may also implement the selection procedure for uplink transmissions. The apparatus may also transmit, to the base station, at least one uplink transmission based on the selection procedure for uplink transmissions.

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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information indicating a timing configuration for candidate positions of a discovery reference signal (DRS) window, wherein the DRS window is within an unlicensed millimeter wave (mmW) band, and wherein the timing configuration provides for repetition of a synchronization signal block (SSB) within the DRS window based at least in part on a wraparound scheme; and scan for the SSB in accordance with the timing configuration. 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 physical random access channel (PRACH) preamble configuration that indicates a first preamble format for a first PRACH preamble and a second preamble format for a second PRACH preamble, wherein the first preamble format is different from the second preamble format. The UE may transmit the first PRACH preamble as part of a random access procedure based at least in part on the PRACH preamble configuration, wherein transmitting the first PRACH preamble enables a determination of a symbol boundary offset. The UE may transmit the second PRACH preamble as part of the random access procedure based at least in part on the PRACH preamble configuration, wherein transmitting the second PRACH preamble enables a determination of a symbol timing offset. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for synchronization signal block (SSB) patterns with gaps. A method that may be performed by a network entity (e.g., a BS) generally includes determining a synchronization signal block (SSB) pattern that identifies SSB positions for sweeping a set of SSB beams over multiple SSB bursts with gaps between at least some of the SSB positions, wherein the SSB pattern identifies a subset of the set of SSB beams to use per SSB burst. The method generally includes transmitting SSBs over the multiple SSB bursts in accordance with the pattern.
