    Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may generate statistical modeling of sensing outcomes (e.g., may identify one or more measurement statistics), and may transmit values that are quantized based on the one or more measurement statistics. Measurement statistics may include one or more of mean and variance of sensing results (e.g., channel quality measurements such as signal to interference ratio (SIR)), auto-correlation of measurements or measurement statistics over time, auto-covariance, or the like. In some examples, a UE may incorporate channel measurement statistics into a waveform (e.g., the coordination report) or otherwise compress the measurements. The UE may measure its own self-interference, and may indicate (e.g., in the coordination message) resource availability that reflects the measured self-interference. A receiving UE may use the coordination message to schedule subsequent sidelink communications (e.g., with the transmitting UE or with other UEs).

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, in a first broadcast message from a second UE, an indication of one or more sidelink resources in a resource selection window of a sidelink channel that are available for transmission by the second UE to a third UE. The UE may sense the sidelink channel. The UE may select one or more candidate sidelink resources that are available for a fourth UE to use for transmission to the first UE based at least in part on the indication in the broadcast message and the sensing of the sidelink channel. The UE may transmit, to the fourth UE in a second broadcast message, an indication of the candidate sidelink resources that are available for the fourth UE. Numerous other aspects are described.

    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: 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.
