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: Methods, systems, and devices supporting flexible frequency domain resource allocation (FDRA) for sidelink are described. For example, a wireless device may receive, over a sidelink channel, control information including a parameter associated with a first FDRA of a first transport block (TB) associated with an initial transmission and an indication of a second FDRA of a second TB associated with a subsequent transmission after the initial transmission. The wireless device may identify the first FDRA of the first TB based on receiving the control information and may communicate one or more signals over the sidelink channel based on identifying the first FDRA of the first TB and receiving the indication of the second FDRA of the second TB. In some examples, the wireless device may receive, over a second sidelink channel, second control information including a second parameter associated with a size of the second TB.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device, such as a user equipment (UE), may be configured to communicate with one or more other wireless devices (e.g., another UE) via sidelink communications. The first wireless device may receive an indication of a schedule of resources for sidelink communications to be performed over a communication beam, the schedule indicating a set of resources corresponding to a beam configuration for the sidelink communications with a second wireless device. The first wireless device may communicate with the second wireless device via one or more sidelink channels based on configuring the communication beam using the beam configuration over the set of resources. In some examples, the indication of the schedule of resources may be received in a confirmation of the schedule established by the second wireless device or, in some examples, in a request to establish the schedule.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device (base station or UE) may receive an indication of a listen before talk (LBT) gap for sharing a channel occupancy time (COT), the COT being acquired by another wireless device (base station or UE), and detect whether a slot within the COT is occupied by the other wireless device, the slot occurring prior to the LBT gap. The wireless device may also, responsive to detecting that the slot is occupied by the other wireless device, perform an LBT procedure during the LBT gap, and, responsive to a successful LBT procedure, transmit a signal to the other wireless device within the COT.

Abstract: Methods, systems, and devices for wireless communications are described. A sidelink message may be scheduled for a UE during a first short transmission time interval (TTI). The first short TTI and a second short TTI for transmitting a sidelink feedback message corresponding to the sidelink message may both be shorter in duration than a another, longer type of TTI. The UE may transmit automatic gain control information in a first symbol period of the second TTI, transmit the sidelink feedback message in a second symbol period of the second TTI (after the first symbol period of the second TTI), and switch from operating in a transmitting mode to operating in a receiving mode during a third symbol period of the second TTI (after the second symbol period of the second TTI).

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support controlling transmit power of one or more groups of user equipment (UE) sidelinks using a single sidelink control transmission of group transmit power control (TPC) information. A first UE may transmit group TPC information to one or more groups of UEs, such as by including the group TPC information in sidelink control information (SCI). The group TPC information may include a group TPC indicator and one or more TPC messages for providing one or more group TPC commands with respect to groups of sidelinks. The group TPC commands may provide for power control with respect to a respective group of UEs for one or more channels. Other aspects and features are also claimed and described.

Abstract: Wireless communications systems and methods related to multi-hop sidelink are provided. In one aspect, a first user equipment (UE) receives, from a base station (BS), a configured grant (CG) indicating a first CG occasion. The first CG occasion includes a first transmit resource and a first receive window. The first UE receives, from a second UE in the first receive window, a first communication signal including a first data block. The first UE transmits, to a third UE in the first transmit resource, a second communication signal including the first data block.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on an access link from a base station, a first downlink control information (DCI) that schedules a first communication on a physical sidelink shared channel (PSSCH) and a second DCI that schedules a second communication on the PSSCH. The first communication and the second communication may be scheduled according to a rule for overlapping or ordering communications on the PSSCH that are associated with one or more hybrid automatic repeat request identifiers. The UE may transmit the first communication and the second communication as scheduled. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support configured reception with sidelink control information (SCI) repetition over a sidelink. In aspects, a receiving user equipment (UE) may be configured to conduct combined reception/decoding of SCI repetitions (received from a transmitting UE over a sidelink) over multiple time-frequency slots at pre-defined occasions (e.g., occasions configured by a base station) to decode a sidelink transmission. In aspects, a receiving UE may receive from a transmitting UE over a sidelink, a sidelink transmission during a reception occasion that includes a plurality of reception opportunities for the receiving UE. Each reception opportunity of the plurality of reception opportunities includes a repetition of an SCI. The receiving UE decodes the SCI by combining the repetitions of the SCI received in one or more reception opportunities, and decodes a data transmission (e.g., a physical sidelink shared channel (PSSCH) transmission) using the decoded SCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may transmit a stage one sidelink control information (SCI) message to multiple receiver UEs. In some aspects, the stage one SCI message may indicate respective resource reservations for multiple sidelink transmissions to the multiple receiver UEs. The transmitter UE may transmit a physical sidelink shared channel (PSSCH) to a subset of the multiple receiver UEs based at least in part on a configured grant associated with the subset of the multiple receiver UEs and the respective resource reservations indicated in the stage one SCI message. Numerous other aspects are provided.
