Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate configured grant uplink control information (CG-UCI) based at least in part on a determination that a configured grant (CG) retransmission timer is not configured. The UE may transmit the CG-UCI on a physical uplink channel to a base station. In some aspects, the UE may receive a configuration indicating that retransmission on a CG resource is enabled, in association with a determination that a CG retransmission timer is not configured. The UE may transmit a retransmission on the CG resource based at least in part on receiving a message that includes hybrid automatic repeat request feedback for one or more CG communications. Numerous other aspects are provided.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may receive, from a base station, SPS via RRC signaling. The apparatus may also determine a UE Rx-Tx time difference, the UE Rx-Tx time difference being equal to a difference between a downlink subframe reception time and an uplink subframe transmission time. The apparatus may also transmit, to the base station, the UE Rx-Tx time difference or receive, from the base station, a base station Rx-Tx time difference, the base station Rx-Tx time difference being equal to a difference between an uplink subframe reception time and a downlink subframe transmission time.

Abstract: Wireless communication systems and methods related to channel occupancy time (COT) sharing when operating in a frame-based-equipment (FBE) mode over a shared frequency band are provided. In one aspect, a user equipment (UE) contends for a channel occupancy time (COT) in a first frame-based equipment (FBE) frame. The UE transmits, to a base station (B S), an uplink communication signal during a first portion of the COT. The UE receives, from the BS based on COT sharing information, a downlink communication signal during a second portion of the COT, wherein the second portion is non-overlapping with the first portion

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: 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: 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: A method for wireless communication performed by a wireless device includes aggregating a number of component carriers (CCs) to generate a virtual CC. The method also includes allocating data channel resources in the virtual CC based on a virtual bandwidth part (BWP) and allocating control channel resources in the virtual CC based on the virtual BWP. The method further includes communicating on a data channel based on the allocated data channel resources and communicating on a control channel based on the allocated control channel resources.

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.
