Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from another UE, a coordination message that includes resource information (e.g., a preference status) for communication resources. The UE receiving the coordination message may determine a status of one or more resources based on the resource information, an intended recipient of the coordination message (e.g., based on a destination identifier of the coordination message), or a communication connection associated with the one or more resources. The status may indicate that a respective resource of the one or more resources is available, reserved, preferred, or non-preferred, or some combination thereof. In some examples, the one or more resources may be for a sidelink connection or a unicast connection. The receiving UE may utilize the determined status to select one or more resources for a sidelink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. The techniques described herein relate to new radio (NR) sidelink and long-term evolution (LTE) sidelink co-channel coexistence for stand-alone NR user equipment. A user equipment (UE) identifies a resource pattern for a set of resources for sidelink communications, the set of resources including a first subset of resources associated with a first radio access technology (RAT) (e.g., LTE) and a second subset of resources associated with a second RAT (e.g., 5G NR). The UE performs a channel busy ratio (CBR) measurement for a resource of the set of resources. The UE adjusts the resource pattern for the set of resources based on the CBR measurement.

Abstract: Apparatus, methods, and computer-readable media for acknowledgment feedback for groupcast option 1 sidelink communication are disclosed herein. An example method of wireless communication at a receiving user equipment (UE) includes determining whether a data signal associated with a groupcast transmission from a transmitting UE is decodable at the receiving UE and obtaining measurements of the data signal when the data signal is decodable at the receiving UE. The example method also includes determining whether the measurements exceed a threshold and transmitting a first type of feedback to the transmitting UE when the measurements do not exceed the threshold. An example method of wireless communication at a transmitting UE includes receiving, from a receiving UE over a sidelink channel, feedback comprising the first type of feedback when the first UE is determined to monitor for the first type of feedback and a second type of feedback from a plurality of UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE via reflection by one or more passive devices, a first reference signal (RS) that is based at least in part on a shared first key that corresponds to a configuration of the one or more passive devices. The first UE may receive, from the second UE via reflection, a second RS that is based at least in part on the first key. The first UE may generate a second key based at least in part on a measurement of the second RS. The first UE may transmit a positioning reference signal that is based at least in part on the second key and that is associated with a measurement of a range between the first UE and the second UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive a sidelink message via a sidelink transmission resource of a shared sidelink resource pool that is shared between a communications according to a first radio access technology (RAT) and communications according to a second RAT. The UE may map sidelink transmission resource occasions of the shared resource pool to a physical sidelink feedback channel (PSFCH) occasion and map subchannels of the sidelink transmission occasions to respective resources of the PSFCH occasion. The UE may transmit a sidelink feedback message corresponding to the sidelink message using a resource of the PSFCH occasion corresponding to a subchannel carrying sidelink control information of the sidelink message.

Abstract: In some aspects, a method of wireless communication includes performing a full reference signal receive power (RSRP) sweep for a first slot to determine a first resource exclusion RSRP threshold, and performing a resource reevaluation for a second slot based on the first resource exclusion RSRP threshold from the first slot. In some aspects, a method of wireless communication may include performing a full RSRP sweep for a first slot to determine a first resource exclusion RSRP threshold and performing the full RSRP sweep for a second slot that is a number of slots following the first slot to determine a second resource exclusion RSRP threshold. For each slot between the first slot and the second slot, the resource reevaluation may be performed based on the first resource exclusion RSRP threshold determined for the first slot.

Abstract: Certain aspects of the present disclosure provide techniques for configuring sidelink communications between user equipment's (UEs). Per one technique, during a discovery opportunity, a first UE and a second UE may identify a subset of beam pairs suitable for communication, and schedule a discontinuous transmission (DTX) occasion during the discovery opportunity. During the DTX occasion, the first UE and second UE may perform a beam refinement procedure to determine a beam pair (BP) over which to communicate, from the identified subset of beam pairs. The beam refinement procedure may include beam narrowing of at least one of the identified subset of beam pairs.

Abstract: Techniques for wireless communications are described. A user equipment (UE) may be configured with one or multiple transmission and reception points (TRPs). The UE may support sidelink communications, which may be referred to as vehicle-to-everything (V2X) communications systems, vehicle-to-vehicle (V2V) communications systems, and the like. The UE may provide improvements to resource determination for the sidelink communications by determining whether multiple peer UEs can be space-division multiplexed over time and frequency resources. To mitigate interference between the multiple peer UEs, the UE may transmit a power control request message to one or multiple peer UEs to adjust a transmit power level, and a receive a power control response message from the one or multiple peer UEs accepting or rejecting the transmit power level adjustment. As a result, the UE may experience efficient sidelink operations.
