Abstract: Wireless communications systems and methods related to discovery signaling for sidelink communication are provided. In one aspect, a first user equipment (UE) transmits, to a second UE in a first slot and a first portion of a subband of a shared frequency band, a synchronization communication, where the synchronization communication indicates a location of a discovery signal in a second portion of the subband of the shared frequency band. The first UE also transmits, to the second UE in the first slot and in the second portion of the subband of the shared frequency band, the discovery signal.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a user equipment (UE) and a base station. The UE receives a configuration for a plurality of semi-persistent scheduling (SPS) occasions each SPS occasion including multiple opportunities for a downlink transmission by a base station. The UE monitors for the downlink transmission during one or more opportunities of an SPS occasion. The base station transmits a packet to the UE in an opportunity of an SPS occasion based on an arrival time of the packet. In various configurations, a base station may transmit first information via a first communication opportunity and second information via a second communication opportunity of that same SPS occasion. A wireless communication device may monitor all communication opportunities of an SPS occasion to decode the information sent in two or more of the communication opportunities of the SPS occasion.

Abstract: Certain aspects of the present disclosure provide techniques for determining and using channel ratio metrics for beamformed communication. A method that may be performed by a user equipment (UE) includes selecting a first beam of a plurality of beams for determining one or more channel ratio metrics, determining the one or more channel ratio metrics for the first beam, wherein determining the one or more channel ratio metrics is based, at least in part, on an angular separation between the first beam and one or more neighboring beams of the plurality of beams, and transmitting signaling via the first beam based on the one or more channel ratio metrics

Abstract: CG-based sidelink beamforming alignment is disclosed. The initiator UE may receive, from a base station, a CG indicating one or more CG resources for a beamforming alignment procedure. The initiator UE may transmit, to at least one responder UE via one or more Tx beams on the one or more CG resources, beam-sweeping SCI for the beamforming alignment procedure. The beam-sweeping SCI may include at least one of: a Tx beam index, a time period to monitor for beam-feedback SCI, or a time window including CG occasions for a same beam transmission of ACK SCI. The initiator UE may monitor, over the time period, for beam-feedback SCI from the at least one responder UE. The initiator UE may receive, from the at least one responder UE, the beam-feedback SCI within the time period.

Abstract: Certain aspects of the present disclosure provide techniques for application of a repetition factor to uplink (UL) control channels. A method that may be performed by a user equipment (UE) includes receiving, on a downlink (DL) control channel, an indication of a configuration for repetition of a UL control channel scheduled by the DL control channel and another UL control channel, wherein the configuration is applied for repetition of the other UL control channel after a configured time period starting from reception of the DL control channel; and transmitting the repetition of the UL control channel and the repetition of the other UL control channel in accordance with the configuration.

Abstract: Techniques and apparatus for providing hybrid automatic repeat request (HARQ) feedback for multiple physical downlink shared channel (PDSCH) transmissions are described. One example technique involves receiving downlink control information (DCI) scheduling a plurality of downlink data transmissions across a plurality of slots. The plurality of downlink data transmissions are monitored across the plurality of slots. At least one HARQ feedback scheme for acknowledging the plurality of downlink data transmissions is determined. HARQ feedback for the plurality of downlink data transmissions is provided in accordance with the at least one HARQ feedback scheme.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for beam formed partial sensing by a user equipment (UE). An example method generally includes performing partial sensing by monitoring for sidelink transmissions from one or more other UEs using one or more different beams during one or more different portions of a sensing window; and selecting resources, within a resource selection window, for future sidelink communications based on results of the partial sensing.
