Abstract: Certain aspects of the present disclosure provide techniques for sidelink assisted retransmissions, in which a first UE obtains first data intended for a second UE by decoding a first transmission of the first data targeting the second UE, receives signaling indicating the first UE is to retransmit the first data to the second UE, and retransmits the first data to the second UE, via a sidelink, in response to the signaling.

Abstract: This disclosure provides systems, methods, apparatuses, and computer-readable media for multiplexing channel state information (CSI) reports in scenarios involving multiple transmit-receive points (TRPs). In one aspect, a user equipment (UE) may receive at least one configuration that identifies a resource for multiplexing CSI reports that have a potential to collide in a slot. The UE may receive the at least one configuration from either, or both, of a first TRP or a second TRP. The UE may transmit at least one of a first set of CSI reports to the first TRP or a second set of CSI reports to the second TRP, multiplexed in the resource, according to the at least one configuration.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for physical uplink control channel (PUCCH) resource configuration. In one aspect, a base station may schedule a user equipment (UE) for PUCCH transmission based on a time division orthogonal cover code (TD-OCC) or a set of TD-OCCs, a cyclic shift step size or a set of cyclic shift step sizes, a first symbol or a set of first symbols, or a cyclic shift set. The base station may distinguish communications from that UE based on the TD-OCC or set of TD-OCCs, the cyclic shift step size or set of cyclic shift step sizes, the first symbol or set of first symbols, or the cyclic shift set.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a plurality of slot-aggregated physical uplink shared channel (PUSCH) transmissions associated with a common transport block; receive a dynamic feedback information (DFI) transmission that includes hybrid automatic repeat request (HARQ) feedback associated with the plurality of slot-aggregated PUSCH transmissions, wherein the HARQ feedback is a HARQ acknowledgement (ACK) or a HARQ negative acknowledgement (NACK); determine whether one or more PUSCH transmissions, of the plurality of slot-aggregated PUSCH transmissions, satisfy a delay condition associated with receipt of the DFI transmission; and determine whether the HARQ feedback is valid based at least in part on whether the one or more PUSCH transmissions satisfy the delay condition. Numerous other aspects are provided.

Abstract: Techniques for defining a reference duration and one or more reference transmissions that are utilized for contention window update are provided to address these new features. An apparatus, such as a wireless device, determines a reference duration of a channel occupancy time (COT), the reference duration based at least in part on a subcarrier spacing (SCS) and based on reception of a physical downlink shared channel (PDSCH) transmission. The apparatus updates a contention window (CW) based at least in part on reception of the PDSCH transmission during the reference duration. For example, the apparatus may increase the CW when a negative acknowledgement (NACK) is received for the determined PDSCH in the COT and may assign CW with a predetermined minimum value (CW_min) when a positive acknowledgement (ACK) is received for the determined PDSCH.
