Abstract: Aspects of the present disclosure provide techniques for handling scenarios where a physical uplink shared channel (PUSCH) repetition is scheduled as a single symbol. According to certain aspects, a user equipment (UE) is configured to detect that a nominal physical uplink shared channel (PUSCH) repetition is to be segmented into one or more actual PUSCH repetitions that include a single symbol actual PUSCH repetition and take one or more actions to handle a symbol length gap in transmission due to the single symbol actual PUSCH repetition.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently identifying resources for transmitting one or more sidelink synchronization signal blocks (S-SSBs) in the shared spectrum or efficiently beam sweeping multiple S-SSBs in the shared spectrum. In one aspect, a user equipment (UE) may transmit an S-SSB in a sidelink bandwidth part (BWP) in the shared spectrum such that a lower edge of the S-SSB is aligned with or offset from a lower edge of the sidelink BWP. In another aspect, a UE may beam sweep S-SSBs in one or more S-SSB bursts in a S-SSB period to improve the chances that another UE may receive the S-SSBs. In yet another aspect, resources allocated for S-SSB transmissions may facilitate flexible S-SSB transmissions while minimizing gaps to prevent other UEs from incorrectly determining that a sidelink BWP in a shared spectrum is clear for transmission.

Abstract: Certain aspects of the present disclosure provide techniques for multiplexing aperiodic channel state information (AP-CSI or A-CSI) or semi-periodic CSI (SP-CSI) on multiple physical uplink share channel (PUSCH) repetitions. For example, according to certain aspects, a method for wireless communications at a user equipment (UE) includes obtaining signaling indicating that the UE is to multiplex aperiodic channel state information (A-CSI) with the at least two PUSCH repetitions when one or more conditions are met, obtaining signaling scheduling the UE to transmit the at least two PUSCH repetitions, wherein the at least two PUSCH repetitions are associated with a first sounding reference signal (SRS) resource set, and outputting the at least two PUSCH repetitions for multiplexing with the A-CSI based on the signaling indication and the one or more conditions.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may identify a configuration of sidelink synchronization signal block instances including a first quantity of sidelink synchronization signal block instances for each of a plurality of sidelink synchronization signal block periods. The UE may transmit a second quantity of sidelink synchronization signal block instances over a first sidelink synchronization signal block period. In some aspects, the UE may transmit a sidelink synchronization signal block burst using beams in a sidelink synchronization signal block period. The UE may identify a configuration for a set of resources of a sidelink beam selection resource pool based on transmitting the sidelink synchronization signal block burst. The UE may receive, from another UE over the set of resources, a control message including an indication of preferred beams. The UE may transmit the sidelink data to the other UE using the preferred beams.

Abstract: This disclosure provides methods, devices, and systems for resource selection supporting the identification of resources for receiving two-stage downlink control information (DCI). In some systems, for example, a base station may transmit a first stage DCI and a second stage DCI to a user equipment. The first stage DCI may include control information for a group of UEs including the UE and the second stage DCI may include control information that is specific to the UE. The UE may determine a resource to use for receiving the second stage DCI based on an indication in the first stage DCI. In some examples, the UE may determine a resource from a resource pool based on a resource selector included in the first stage DCI and receive the second stage DCI over the determined resource. The resource pool may be indicated by the first stage DCI or pre-configured at the UE.

Abstract: A method of wireless communication performed by a user equipment (UE) incudes receiving supplemental semi-persistent scheduling (SPS) via radio resource control (RRC) signaling. The method also includes receiving the downlink re-transmissions according to the supplemental SPS. A method performed by the UE also includes receiving downlink feedback information (DFI) for a packet and determining one or more of resource block allocation, a start and length indicator value (SLIV), or a number of repetitions for re-transmission of the packet in response to the DFI. The method further includes re-transmitting the packet during a re-transmission period based on one or more of the resource block allocation, the SLIV, or the number repetition.
