Abstract: Apparatus, methods, and computer-readable media for multiplexing of overlapped uplink channel transmission repetitions are disclosed herein. A user equipment (UE) may determine whether a first subset of a first set of uplink channel transmission repetitions overlaps with a downlink transmission and determine whether to transmit a second subset of the first set of uplink channel transmission repetitions when the first subset overlaps with the downlink transmission. In some aspects, the second subset includes one or more uplink channel transmission repetitions that do not overlap with the downlink transmission. The UE may transmit, to a base station over an uplink channel, a second set of uplink channel transmission repetitions having the first subset and the second subset of the first set of uplink channel transmission repetitions when the second subset is determined to be transmitted. Thus, the reliability of uplink repetitions can be increased.

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: 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: Certain aspects of the present disclosure provide techniques for configuring sidelink slots without symbols for automatic gain control. One aspect provides a method for wireless communication by a user equipment, including receiving a first cyclic prefix of a first symbol within a slot at the user equipment. The method further includes configuring a first automatic gain control setting based on a received power in the first cyclic prefix of the first symbol, and receiving a data portion of the first symbol using the first automatic gain control setting.

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.

Abstract: Techniques for enabling a wireless communication device (e.g., a user equipment, UE) to select an energy detection (ED) threshold for a transmission on a wireless communication channel where access to the channel is gained through the use of a listen-before-talk (LBT) procedure. In some examples, a UE may select the ED threshold based on the priority of traffic to be transmitted during the COT. For example, a base station (e.g., gNB) may indicate a priority for uplink traffic and the UE may select an ED threshold based on that priority. In some examples, the UE may select the ED threshold based on the type of grant (e.g., dynamic grant or configured grant) that scheduled the transmission of uplink traffic during the COT. In some examples, the gNB may send information to the UE that indicates the ED threshold to be used for different priorities and/or different types of grants.
