Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink cancellation indication that indicates a set of resources in which to cancel sidelink communications, wherein the set of resources overlaps with at least one of a physical sidelink feedback channel (PSFCH), a gap symbol, or a sidelink synchronization signal block (S-SSB). The UE may perform one or more sidelink cancellation actions associated with the at least one of the PSFCH, the gap symbol, or the S-SSB. Numerous other aspects are described.

Abstract: Various aspects of the disclosure relate to event triggers for independent links. For example, an event trigger may be based on measurements from 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, an event trigger may be based on aggregated measurements from multiple links.

Abstract: The apparatus may be a device at a UE or a base station. The UE (or base station) may be configured to measure a phase noise of a first local oscillator associated with a first port. The UE (or base station) may further be configured to configure, based on the measured phase noise, an allocation of a first set of one or more REs of a PUSCH (or PDSCH) for at least one PT-RS associated with the first port. The first set of one or more REs may include multiple layers associated with a multiple-layer single-carrier waveform transmission. The UE (or base station) may also be configured to transmit, to a base station (or a UE), the PUSCH (or PDSCH) including the at least one PT-RS, the at least one PT-RS being transmitted via the configured allocation of the first set of one.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive a configuration for periodic communications, wherein the configuration indicates a periodicity for the periodic communications. The wireless communication device may receive an indication of whether the periodicity applies to at least one of full duplex resources or half duplex resources. The wireless communication device may communicate based at least in part on the configuration for periodic communications, the periodicity, and the indication. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to communicating information are provided. A method of wireless communication performed by a user equipment (UE) may include mapping a sub-physical sidelink shared channel (sub-PSSCH), sidelink control information (SCI), and an automatic gain control (AGC) symbol to a sub-slot of a plurality of sub-slots of a slot and transmitting, to at least one other UE, a transport block via the sub-PSSCH of the sub-slot.

Abstract: This disclosure provides systems, methods and apparatuses for indicating sidelink processes for sidelink feedback. A second user equipment (UE) may request hybrid automatic repeat request (HARQ) responses from a first UE for a particular set of sidelink processes over a physical sidelink feedback channel. To indicate multiple sidelink processes, the second UE may indicate, in sidelink control information, a window of sidelink processes. The window may be a sliding window that starts with a starting sidelink process and extends through other sidelink processes. The second UE may transmit data for the sidelink processes in the sliding window and receive feedback for the indicated sidelink processes. In some aspects, the first UE may select, in coordination with the second UE, the sidelink processes for which feedback is to be provided.

Abstract: Some aspects described herein relate to configuring user equipment (UE) for transmitting sidelink communications. A sidelink grant for transmitting sidelink communications over multiple contiguous subchannels across multiple resource block (RB) sets in a slot can be received. A listen-before-talk (LBT) procedure can be performed over the multiple RB sets in the slot. Sidelink communications can be transmitted to one or more other UEs in the multiple contiguous subchannels across at least a subset of the multiple RB sets in the slot for which the LBT procedure succeeds

Abstract: Certain aspects of the present disclosure provide techniques for waveform parameters adaptation. Aspects provide for adapting waveforms to account for impairments that can occur when communicating in a high frequency band. A method that may be performed by a base station (BS) includes detecting one or more impairment conditions. The method includes determining a plurality of waveform parameters to adapt in response to the detected one or more impairment conditions. The method includes signaling the plurality of adapted waveform parameters to a user equipment (UE).
