Abstract: Devices, systems, and methods for configuring and indicating sidelink resources for shared or unlicensed frequency bands include configuring PSFCH resource sets using frequency interlaces of one or more PRBs. A first wireless communication device may transmit a plurality of sidelink PRB bitmaps, each associated with a PSFCH occasion or candidate. Each bit in the bitmap may indicate one PRB in the configured resource pool. The PSFCH resource sets may be partitioned by indexing the PRBs according to an interlace-first indexing sequence, and selecting contiguous subsets of indices to form the PSFCH resource sets.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. The UE may be configured to support uplink power control for multiple random access channel (RACH) procedures. A medium access control layer entity at the UE may maintain multiple sets of counters and parameters for multiple simultaneous RACH procedures. In some cases, the UE may perform simultaneous RACH procedures with network entities associated with different timing advance groups, and the UE may associate the counters and parameters of the RACH procedure with the timing advance group. In other cases, the UE may associate the counters and parameters of the RACH procedure with multiple control resource set pool indexes which may correspond to multiple transmission reception points. Each set of counters may be associated with an uplink power control that the UE may use to determine the PRACH transmission power for each RACH procedure.

Abstract: A method for wireless communication at a relay user equipment (UE) includes receiving, from a network node, a first message indicating one or more parameters associated with a relay synchronization signal block (SSB). The method also includes receiving, from the network node, a second message instructing the relay UE to transmit the relay SSB in accordance with the one or more parameters. The method further includes transmitting, to one or more out-of-coverage (OOC) sidelink (SL) UEs via an SL channel, a third message including the relay SSB in accordance with receiving the second message.

Abstract: Various aspects of the disclosure relate to power control for independent links. For example, power control at a device may be based on transmissions on multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, power control for the first device may be based on power control commands received on multiple links. In some scenarios, a power control constraint may be met taking into account the transmission power on multiple links.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving, from a network device, a number of transmissions. The method also includes generating an original hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook based on whether each of the number of transmission is successfully decoded. The method further includes converting a block of k HARQ-ACK bits from the original HARQ-ACK codebook into a partition. A number of partitions for a number of blocks corresponds to quantized HARQ-ACK bits. The method still further includes transmitting the quantized HARQ-ACK bits to the network device.

Abstract: A method for wireless communication by a user equipment (UE) includes receiving, from a network node, a group of downlink transmissions. The method also includes forming a first hybrid automatic repeat request (HARQ)-acknowledgement (ACK) part and a second HARQ-ACK part associated with a HARQ-ACK payload in accordance with a transformation scheme. The HARQ-ACK payload may include HARQ feedback for each one of the group of downlink transmissions. A size of the second HARQ-ACK part may be a function of the first HARQ-ACK part. The method also includes separately encoding the first HARQ-ACK part and the second HARQ-ACK part. The method further includes transmitting, to the network node, the encoded first HARQ-ACK part and the encoded second HARQ-ACK part.

Abstract: Method and apparatus for PUSCH selection for UCI multiplexing. The apparatus determines that a transmission of UCI would at least partially overlap in time with transmissions of a set of PUSCHs. The set of PUSCHs including a plurality of PUSCHs on a same CC that are at least partially overlapping in time. The apparatus selects one PUSCH of the set of PUSCHs for multiplexing the UCI. The selection of the one PUSCH being based at least partially on a group association between the UCI and each PUSCH of the set of PUSCHs, or one or more transmission parameters of each PUSCH of the plurality of PUSCHs. The apparatus multiplexes the UCI on the selected one PUSCH for simultaneous transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) transmits a signal in accordance with a shortened time domain precoding filter for multi-antenna precoding. In some examples, a UE may precode the signal in accordance with a subset of time domain precoding taps. The UE may select the subset of time domain precoding taps from a set of time domain precoding taps in accordance with an absolute value of each of the set of time domain precoding taps. The UE may transmit the signal in accordance with the precoding. In other examples, the UE may select a transmit channel shortener to apply to a channel. The UE may select the transmit channel shortener based on a channel energy of a shortened channel that is associated with the transmit channel shortener. The UE may transmit the signal via the shortened channel.

Abstract: Methods, systems, and devices for wireless communication are described. A non-sidelink synchronization signal (SLSS)-transmitting user equipment (UE) may initiate a channel occupancy time (COT) including multiple contiguous slots and a gap slot. The non-SLSS UE may detect an SLSS UE (capable of transmitting sidelink synchronization signal blocks (S-SSBs)) and assume that the gap slot will be filled with an S-SSB. The non-SLSS may transmit a sidelink message during the COT after the gap slot, based on the assumption. Alternatively, based on the SLSS UE indicating that it is capable of transmitting the S-SSB, the non-SLSS UE may schedule transmission of the S-SSB such that the gap slot is filled. If the SLSS UE is incapable of transmitting the S-SSB, the non-SLSS UE may determine a method for transmitting the sidelink message during the already-initiated COT or during another COT.
