    Abstract: Apparatus, methods, and computer-readable media for facilitating a SL communication for mode 2 resource allocation are disclosed herein. An example method includes performing sensing on one or more SL resources to identify a first set of available resources. The example method further includes adjusting a first measurement threshold to a second measurement threshold based on a size of the first set of available resources being below an availability threshold. The example method further includes transmitting a sidelink message indicating a second set of available resources based on the second measurement threshold.

    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first user equipment (UE) may operate in accordance with a multi-user (MU) multiple input-multiple output (MIMO) communication mode and may communicate with multiple other UEs over a same physical sidelink shared channel (PSSCH) resource. In some implementations, the first UE may transmit an indication of an MU-unicast mode for multiple sidelink transmissions to the multiple other UEs and may transmit the multiple sidelink transmissions to the multiple other UEs over the same PSSCH resource. In such implementations, the multiple other UEs may select physical sidelink feedback channel (PSFCH) resources to transmit feedback associated with the multiple sidelink transmissions in accordance with a PSFCH resource selection procedure associated with the MU-unicast mode. In accordance with the PSFCH resource selection procedure, the multiple other UEs may each select different PSFCH resources for their respective feedback transmissions.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may select a set of available sidelink resources in a selection window for communication by a second UE. The first UE may transmit, to the second UE, an inter-UE coordination message that indicates inter-UE coordination information identifying the set of available sidelink resources, wherein the selection window is of a length different than a length of a resource selection window of the first UE. Numerous other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communications are described. A method for wireless communication is described that includes receiving, at a user equipment (UE), via a control channel, configuration information for communications between the UE and a wireless device over reserved resources. The method further includes identifying, from the configuration information, an indication of a channel state information (CSI) report periodicity and transmitting a CSI report for a data channel in accordance with the CSI report periodicity. Another method includes generating a sidelink control information (SCI) message including an indication of a presence or absence of a CSI reference signal (CSI-RS) in a sidelink channel message and transmitting the sidelink control information message. Another method includes receiving a SCI message including an indication of a CSI-RS in a sidelink channel message, and generating and transmitting a CSI report for a data channel based at least in part on the indication.

    Abstract: Apparatus, methods, and computer-readable media for cooperative relay in sidelink networks are disclosed herein. An example method for wireless communication at a first user equipment (UE) includes receiving, from a second UE, a groupcast signal comprising a resource allocation assigned to a plurality of sidelink UEs including the first UE. The example method also includes communicating, with a remote apparatus on a first resource included in the resource allocation, a first relay signal comprising at least a portion of the groupcast signal, in which the first relay signal corresponds to at least a portion of a second relay signal communicated with the remote apparatus on a second resource included in the resource allocation by at least one other sidelink UE of the plurality of sidelink UEs.

    Abstract: Wireless communications systems and methods related to transmitting sidelink channel state information (CSI) from one user equipment (UE) to another UE using a L1 signal. A first UE requests a CSI report from a second UE. The first UE sends a reference signal which the second UE measures to determine channel characteristics. The second UE forms a CSI report which includes a rank indicator, a channel quality indicator, and potentially a precoding matrix index indicator. The second UE forms the CSI report at the PHY level. The CSI report is included in reserved field(s) of a second stage sidelink control information (SCI-2). The first UE receives and processes the CSI report at a PHY level.
