Abstract: Wireless communications systems and methods related to sidelink communication between user equipments (UEs). A first UE determines a power level for a physical sidelink format indicator channel (PSFCH) with multiple interlaced resource blocks (RBs) and/or a common interlace. If a reference power level is provided by a network device such as a base station, the UE may determine power levels based on the reference power level. The UE may also determine power levels based on maximum supported power levels for the UE. In some embodiments, a common interlace uses a fixed percentage of maximum UE power. In other embodiments, available transmit power is evenly split between PSFCH RBs and a common interlace. Priority PSFCH dropping rules may be implemented when scheduled PSFCHs exceed power limitations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first one or more physical sidelink shared channel communications associated with a first set of physical sidelink shared channel priorities and associated with a first feedback message codebook. The UE may receive a second one or more physical sidelink shared channel communications associated with a second set of physical sidelink shared channel priorities and associated with a second feedback message codebook. The UE may include transmit, based at least in part on a physical sidelink feedback channel feedback resource configuration, a first feedback message in a first physical sidelink feedback channel feedback resource and a second feedback message in a second physical sidelink feedback channel feedback resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects more specifically relate to sidelink communications and PSFCH padding. In some aspects, a channel occupancy time (COT) initiating UE may obtain physical sidelink feedback channel (PSFCH) information indicating that a PSFCH transmission is to occupy a common interlace and one or more physical resource blocks. The COT initiating UE may communicate a padding signal within a PSFCH gap of the common interlace in accordance with identifying that the COT initiating UE and the responding UE are not to transmit hybrid automatic repeat request (HARQ) feedback within the PSFCH gap of the common interlace. In some other aspects, the PSFCH information may indicate that the PSFCH transmission is to occupy a dedicated interlace, and the COT initiating UE may communicate a padding signal on a PSFCH resource within the dedicated interlace.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting device may generate a frequency-domain-multiplexed signal by performing frequency domain multiplexing of a data signal and a reference signal within a symbol of a discrete Fourier transform spread orthogonal frequency domain multiplexing waveform communication, the reference signal being one of a demodulation reference signal, a sounding reference signal, or a channel state information reference signal. The transmitting device may transmit, to a receiving device, the frequency-domain-multiplexed signal. 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 an indication of a pair of transmission configuration indication (TCI) states associated with a physical downlink shared channel (PDSCH). The UE may select, based at least in part on the indication, a default beam for receiving information via the PDSCH. Numerous other aspects are described.

Abstract: Some aspects described herein relate to receiving, from a sidelink transmitting user equipment (UE), one or more first transmissions over a first set of sidelink resources, receiving, from the sidelink transmitting UE, one or more second transmissions over a second set of sidelink resources, and transmitting, to the sidelink transmitting UE, second feedback for the one or more second transmissions in a second set of feedback resources, wherein the second feedback also includes, based on a failure associated with first feedback for the one or more first transmissions to be transmitted over a first set of feedback resources, a retransmission of at least a portion of the first feedback. Other aspects relate to receiving the second feedback with the retransmission of at least the portion of first feedback.
