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.

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 transmitting (Tx) user equipment (UE) may receive, from a plurality of receiving (Rx) UEs, indications of channel busy ratios (CBRs) associated with the plurality of Rx UEs, respectively. The Tx UE may combine the CBRs to obtain a combined CBR associated with the Tx UE. The Tx UE may adjust a resource utilization based at least in part on the combined CBR associated with the Tx UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to measure sidelink channel conditions for a group of UEs and transmit a report (e.g., a channel state information (CSI) report) to a base station indicating the sidelink channel conditions. The base station may transmit control information (e.g., group-common downlink control information (GC-DCI)) to the group of UEs triggering the UEs to transmit sidelink reference signals (e.g., CSI reference signals (CSI-RS)) on the sidelink channels so that the UE can measure the sidelink channel conditions and transmit the report. Based on the report, the base station may transmit control information (e.g., a downlink control information (DCI) message) scheduling sidelink communications for the group of UEs. In some examples, the UE may act as a relay node for the group of UEs, and forward control information to the group of UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, via a sidelink interface, a message from a second UE. The UE may transmit, to the second UE, sidelink resource information for sidelink resources that are available to the second UE, wherein the sidelink resource information is based at least in part on a measured power level associated with the message received from the second UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. A user equipment (UE) may receive a first data message in a sub-slot of a slot and in a sub-channel of a sidelink data channel. The UE may select a resource of a sidelink feedback channel based on a first index associated with the slot and a second index associated with the sub-slot within one or more slots comprising the slot. Additionally or alternatively, the UE may select a resource of a sidelink feedback channel from periodic resources having a slot-based periodicity based on an index associated with the sub-slot within one or more slots comprising the slot. The UE may transmit a feedback message associated with the first data message according to the selected resource.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use a lower code rate by splitting a data stream into multiple data sub-streams. The UE may split the data stream to synchronously encode, modulate, and spread the data sub-streams at different layers. Then, the UE may superpose or combine the sub-streams together. The UE may scramble the combined data stream with a UE-specific scrambling code. In some examples, the UE may then apply a cyclic prefix to the combined data stream. The UE may then transmit the combined data stream to a base station. The receiving base station may use layer-wise matched filters and element-wise signal estimators (ESE) to obtain soft information such as log-likelihood ratios. Channel decoders may then determine estimated bits for each layer of each user of the combined data stream.
