Abstract: This disclosure provides systems, methods and apparatus, for measurement and reporting procedures associated with a sidelink positioning reference signal (SL-PRS). In one aspect, a first user equipment (UE), which may function as a sidelink anchor node, may transmit an SL-PRS to a second UE in accordance with a slot format or structure that is dedicated for SL-PRS transmissions. The first UE may select resources for the transmission of the SL-PRS via sensing and exclusion or using a set of resources that are dedicated for SL-PRS transmissions. The second UE may receive the SL-PRS and use the SL-PRS to acquire positioning information, in accordance with an observed time difference of arrival (OTDOA)-based positioning method, or may transmit a second SL-PRS to the first UE to facilitate acquisition of positioning information at the first UE, in accordance with a round-trip-time (RTT)-based positioning method.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, based at least in part on configuration information received from a base station, whether the UE is in a single-transmit receive point (TRP) mode or a multiple-TRP mode. The UE may receive a beam indication that is one of a non-unified beam indication or a unified transmission configuration indicator (TCI) state indication, wherein a type of the beam indication is based at least in part on one or more beam indication rules for the single-TRP mode and the multiple-TRP mode. The UE may communicate with one or more TRPs using one or more beam directions associated with the beam indication. Numerous other aspects are described.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station, a first indication to disable hybrid automatic repeat request (HARQ) feedback for a number of instances of a multicast transport block (TB). The method also includes receiving, from the base station, a second indication identifying a value of the number of instances of the multicast TB. The method further includes receiving, from the base station, one or more instances of the multicast TB. The method still further includes determining, based on the one or more received instances, whether the multicast TB is recoverable. The method further includes selectively transmitting, to the base station, HARQ feedback after all instances of the multicast TB have been transmitted by the base station based on the determination of whether the multicast TB is recoverable.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a first downlink transmission associated with a first priority based at least in part on a first IN downlink grant. The UE may receive, from the network entity, a second downlink transmission associated with a second priority that is higher than the first priority. The UE may drop a first uplink transmission associated with the first downlink transmission based at least in part on the first uplink transmission and a second uplink transmission associated with the second downlink transmission being associated with colliding resources in a slot. The UE may transmit, to the network entity, the first uplink transmission in a next available slot based at least in part on an indication included in the first downlink grant. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a physical downlink shared channel (PDSCH) transmission in a first slot, wherein the PDSCH transmission is associated with a codebook timespan. The UE may perform, to the network entity, a physical uplink control channel (PUCCH) transmission in a subsequent slot based at least in part on an adjustment to the codebook timespan, wherein the PUCCH transmission indicates a hybrid automatic repeat request (HARQ) associated with the PDSCH transmission. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to report feedback to a base station to address polarization impairments in multiple-input multiple-output (MIMO) communications. The UE and the base station may establish a communications link using a pair of orthogonally polarized beams, where the pair of polarized beams may be selected based on a beam sweep procedure. The UE may transmit a report to the base station indicating one or more polarization parameters associated with beam pairs identified in the beam sweep procedure, such as one or more orthogonality parameters, one or more polarization parameters relating to one or more beam pairs, or one or more angular spread parameters. Based on the report, the base station may transmit a beam configuration to the UE for polarization MIMO communications.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may start, from a last transmission of a reference signal resource, a known transmission control indicator (TCI) duration during which a TCI state switch command is to be received. The known TCI duration may end after a maximum time duration and may exclude an invalid period. The UE may receive the TCI state switch command during the known TCI duration. Numerous other aspects are described.

Abstract: Aspects are provided for generation and transmission of MDMRS which allow matching of nonlinear model impact or properties between DMRS and data in DFT-s-OFDM waveforms as well as CP-OFDM waveforms. A UE transmits, to a network entity, an MDMRS generated from a DMRS. The MDMRS has a PAPR distribution matching a PAPR distribution of a signal including data in an uplink channel. A target PAPR of the MDMRS is based on a modulation scheme of the data. The UE also transmits the data in the uplink channel, where the uplink channel includes a PUCCH or a PUSCH. As a result of the ability of MDMRS to match the nonlinear impact of DMRS and PUSCH or PUCCH, the network entity may compensate for any EVM that may occur as a result of PAPR reduction by a nonlinear operator of the UE, and communication performance may thereby be improved.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may generate first and second sets of feedback bits associated with first and second sets of downlink transmissions, respectively, the first and second sets of feedback bits scheduled for transmission in a first set of uplink symbols. The UE may identify, based on a change in a format associated with the first set of uplink symbols, that only a subset of the first set of uplink symbols is available for transmission of the first set of feedback bits and the second set of feedback bits. The UE may determine to defer transmission of one or both of the first set of feedback bits and the second set of feedback bits to a second set of uplink symbols based on availability of the subset of the first set of uplink symbols and on a deferment scheme.
