Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for sidelink resource selection with AD usage awareness. A UE may receive, from one or more ANs, one or more resource usage schedules associated with one or more ADs in communication with the one or more ANs. The UE may combine the one or more resource usage schedules associated with the one or more ADs into a combined resource usage schedule. The usages may be associated with the combined resource usage schedule, which may be indicative of excluded resources for a transmission of the UE. The UE may transmit, based on the combined resource usage schedule, the transmission of the UE on a resource other than the excluded resources.

Abstract: A method of wireless communication by a receiving sidelink user equipment (UE) includes receiving a first original message from a first transmitting sidelink UE. The method also includes receiving, from a network coding device, a network coded (NC) packet that is coded across the first original message and a second original message from a second transmitting sidelink UE. The first original message corresponds to a first transport block. The second original message corresponds to a second transport block. The method further includes transmitting a first negative acknowledgment (NACK) in response to the first transport block being unsuccessfully decoded. The method still further includes transmitting a second NACK in response to the second transport block being unsuccessfully decoded. The method still further includes transmitting a first acknowledgment (ACK) in response to the first transport block being successfully decoded.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from one or more additional UEs, one or more indicators corresponding to one or more resource reservations. Accordingly, the UE may transmit data, to a second UE, on a sidelink channel, with at least one resource reservation, of the one or more resource reservations, indicated within a control element transmitted with the data. For example, the control element may include a list or a bitmap indicating the at least one resource reservation. Numerous other aspects are described.

Abstract: A wireless device can use a channel occupancy time (COT) to reserve a spectrum for sidelink positioning operations in a certain time interval. In some examples, multiple wireless devices can share the same COT for performing sidelink positioning and/or ranging operations using unlicensed or shared spectrum. Some aspects of the disclosure provide various processes for handling scenarios when channel access of the unlicensed spectrum is unsuccessful.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may detect an available bandwidth for transmission of a sidelink positioning reference signal. The transmitter UE may transmit the sidelink positioning reference signal in the available bandwidth, wherein a duration of the sidelink positioning reference signal is based at least in part on the available bandwidth. Numerous other aspects are described.

Abstract: The apparatus may be a UE configured to select, from a plurality of PSFCH resource sub-pools of a PSFCH resource pool for receiving HARQ feedback, a particular PSFCH resource sub-pool for receiving HARQ feedback associated with a particular SL transmission; transmit, to at least one UE, a PSRI identifying the particular PSFCH resource sub-pool; and receive, from the at least one UE, HARQ feedback regarding the particular SL transmission, the HARQ feedback being received via resources in the PSFCH resource sub-pool indicated by the PSRI. The apparatus may be a base station in a Mode 1 resource allocation that may select, from a plurality of PSFCH resource sub-pools of a PSFCH resource pool for receiving HARQ feedback, a particular PSFCH resource sub-pool for receiving HARQ feedback associated with the particular SL transmission and transmit, to a UE, a PSRI identifying the particular PSFCH resource sub-pool.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to another UE, a sidelink channel state information reference signal (S-CSI-RS) and an indication associated with triggering a non-codebook based precoded S-CSI-RS. The UE may receive, from the other UE, the non-codebook based precoded S-CSI-RS. The UE may transmit, to the other UE, a non-codebook based channel state information (CSI) report medium access control (MAC) control element (MAC-CE) that includes an indication of one or more selected precoding beams based at least in part on the non-codebook based precoded S-CSI-RS. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, for a sidelink transmission over an unlicensed band and associated with a medium access control (MAC) protocol data unit (PDU), one or more candidate resources of a set of candidate resources that are within an adaptive effective contention window (ECW). The UE may adjust at least one parameter of the adaptive ECW to determine an adjusted at least one parameter based at least in part on a channel access output associated with the one or more candidate resources. The UE may transmit the MAC PDU using the one or more candidate resources or an additional one or more candidate resources, wherein the additional one or more candidate resources are selected based at least in part on the adjusted at least one parameter. Numerous other aspects are provided.
