Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) or a base station may communicate a set of reference signals on a set of interference measurement resources. The set of interference measurements may be based on a first activation schedule of one or more reconfigurable intelligent surfaces (RISs). The UE or the base station may generate interference measurement information associated with the one or more RISs based on the set of reference signals. The base station may determine a second activation schedule of the one or more RISs or an allocation of resources for communicating with the UE based on the set of interference measurements. The base station may communicate with the UE based on the second activation schedule or the allocation of resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a time offset for synchronization signal resources for synchronization signals associated with a first radio access technology (RAT). The UE may determine the synchronization signal resources and a synchronization periodicity based on the indication and a penetration ratio of UEs associated with the first RAT. The UE may selectively transmit the synchronization signals on the synchronization signal resources and according to the synchronization periodicity. Additionally, or alternatively, the UE may determine that other synchronization signal resources are allocated for a second RAT and may select resources for communications associated with the first RAT based on determining that the other synchronization signal resources are allocated. The UE may perform communications associated with the first RAT based on selecting the resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a collision on a victim resource based at least in part on an aggressor reservation transmitted by a second UE. The first UE may transmit, to the second UE via a sidelink feedback channel, a resource collision indication that indicates at least one of the victim resource or the aggressor reservation, wherein the resource collision indication is multiplexed on one or more resources that are useable for sidelink feedback. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first sidelink user equipment (UE) may detect a second frequency range (FR2) radio link or beam failure between the first sidelink UE and a second sidelink UE. The first sidelink UE may transmit, to the second sidelink UE, an indication of the FR2 radio link or beam failure based at least in part on a first frequency range (FR1) radio resource control (RRC) connection between the first sidelink UE and the second sidelink UE.

Abstract: An apparatus receives, in a transmission from a second UE, an indication of reserved resources for the second UE. The apparatus measures a received power of the transmission from the second UE. The apparatus excludes the reserved resources indicated by the second UE from a set of candidate resources based on the received power of the transmission from the second UE meeting a threshold, where the threshold is based at least in part on whether the reserved resources are associated with a retransmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may communicate, with a second UE, an indication relating to physical sidelink shared channel (PSSCH) beam training. The UE may transmit, to the second UE on symbols included in a transmission time interval, PSSCH data and beam training reference signals to be used by the second UE to perform beam measurements. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described that provide for directional quality of service (QoS) targets of a user equipment (UE) for directional communications to multiple UEs in multiple directions. An application layer of the UE may provide data with multiple different directional QoS targets, that may be mapped to multiple QoS data flows that are each configured with different directional QoS targets such as direction and priority associated with the direction. The data may be duplicated for each of the multiple QoS data flows having different QoS parameters, and each QoS data flow may be transmitted in a different direction using a different beam.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may estimate one or more channel availability parameter values. The UE may then select, based on a co-channel configuration indicating a relationship between channel availability parameter values and patterns of sidelink resources, a pattern of sidelink resources (e.g., LTE resources) on which to transmit NR packets. In some examples, a special UE may receive individual or aggregated reports of channel availability parameter values. The special UE may select a pattern of sidelink resources (e.g., LTE resources) on which one of the reporting UEs is permitted to transmit NR packets, and may transmit a message activating the pattern of sidelink resources to the reporting UE. The reporting UE may then use the activated sidelink LTE resources for transmitting NR packets according to the indicated pattern.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be configured to trigger a sidelink message to one or more UE of set of multiple other UEs. The first UE may then generate the sidelink message based at least in part on the triggering. In some cases, the sidelink message may include time and frequency resource information associated with sidelink control information received and processed by the first UE. The first UE may multiplex the sidelink message with a sidelink data message. The first UE may then transmit the sidelink message multiplexed with the sidelink data message to the one or more UE of the set of multiple other UEs.
