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: 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: The apparatus of the wireless communication may include a first wireless device configured to transmit sidelink control information (SCI) reserving periodic resources for an initial transmission and aperiodic resources for one or more retransmissions over a sidelink, transmit the initial transmission using the periodic resources, and transmit the one or more retransmissions using the aperiodic resources. The apparatus of wireless communication may also include a second wireless device may be configured to receive the SCI indicating the set of resources for the sidelink transmission from the first wireless device, determine a first resource in the set of resources is periodically reserved, and determine one or more remaining resources in the set of resources is aperiodically reserved.

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 first user equipment (UE) may receive, from a base station, control signaling indicating a set of resources of a sidelink channel available for sidelink communication with a second UE. The first UE may receive a sidelink preemption indication indicating that at least a first resource from the set of resources is preempted. The first UE may communicate a sidelink transmission over the sidelink channel with the second UE based on the sidelink preemption indication. In some cases, the first UE may determine whether the SPI satisfies one or more thresholds and the first UE may communicate the sidelink transmission, or refrain from communicating the sidelink transmission, based on determining whether the SPI satisfies the one or more thresholds.

Abstract: Aspects enable and provide techniques for sidelink communication resource configuration and management. A first user equipment (UE) negotiates with a second UE to select a first communication resource set (ComReSet) from a plurality of ComReSets for sidelink communication. Each of the plurality of ComReSets has a corresponding periodicity of one or more hyper-frames. The first UE communicates with the second UE using the first ComReSet using a frame timing synchronized with the corresponding periodicity of the first ComReSet.
