Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of available resources for a sidelink transmission by performing an iterative resource exclusion procedure, wherein performing the iterative resource exclusion procedure comprises determining, for an iteration, a set of potentially available resources that is based at least in part on a primary resource set and an auxiliary resource set, wherein the auxiliary resource set comprises a first resource of a set of sidelink resources in a resource selection window having a corresponding reference signal received power (RSRP) measurement that is less than an RSRP measurement corresponding to a second resource, and wherein the primary resource set includes the second resource. The UE may transmit the sidelink transmission using the set of available resources and at least one transmitter-receiver point of the UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for are described. A user equipment (UE) may transmit, via a first transmission-reception point (TRP), a first sidelink control information (SCI) scheduling a first sidelink transmission from the UE, the first SCI including an indication that a first hybrid automatic repeat request (HARQ) process associated with the first sidelink transmission is enabled. The UE may transmit, via a second TRP different from the first TRP, a second SCI scheduling a second sidelink transmission from the UE, the second SCI including an indication that a second HARQ process associated with the second sidelink transmission is disabled. The UE may transmit the first sidelink transmission and the second sidelink transmission via the first TRP and the second TRP, respectively, based on transmitting the first and second SCI. The UE may monitor, via the first TRP, for a feedback message based on transmitting the first sidelink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a second UE a sidelink control information transmission associated with a first transmission configuration indicator (TCI) state over a sidelink channel. The first UE may determine that the sidelink control information transmission reserves time and frequency resources for a sidelink data transmission associated with a second TCI state. In some examples, the second TCI state may be different from the first TCI state. The first UE may then selectively enable or disable a resource protection procedure for the reserved time and frequency resources based on the determination and a signal strength associated with the first TCI state or the second TCI state, a network congestion parameter, or a data priority associated with the sidelink data transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may determine a communication collision between a first reservation, by a second UE, of a sidelink resource and a second reservation of the sidelink resource based at least in part on a first set of estimated reference signal received quality (RSRQ) values associated with the first reservation and a second set of estimated RSRQ values associated with the second reservation, wherein the first set of estimated RSRQ values corresponds to a plurality of transmitter-receiver points (TRPs) of the first UE, and wherein the second set of estimated RSRQ values corresponds to the plurality of TRPs. The UE may perform an action based at least in part on identifying the communication collision. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a vehicle-to-everything (V2X) packet. The UE may duplicate, at a protocol stack layer of the UE, the V2X packet to form a plurality of duplicated V2X packets, wherein each duplicated V2X packet is associated with a directional range. Numerous other aspects are provided.

Abstract: Methods, systems (100, 200), and devices (605, 705, 905) for wireless communications are described. For example, a method may include a receiving user equipment (UE) (115) identifying a measurement accuracy threshold associated with reporting a sensor measurement over a wireless communication link (125, 135) to the receiving UE (115). The receiving UE (115) may then transmit, to a measuring UE (115), a configuration indicating the measurement accuracy threshold for reporting to the receiving UE (115). The measuring UE (115) may make sensor measurements and identify measurement data that satisfies the measurement accuracy threshold based on the received configuration. The measuring UE (115) may then transmit, over the wireless communication link (125, 135), the subset of measurement data that satisfies the measurement accuracy threshold. The measuring UE (115) may refrain from transmitting a different subset of measurement data that does not satisfy the measurement accuracy threshold. Thus, improving communication quality by reducing the transmission of unnecessary sensor data and reducing over-the-air congestion.

Abstract: Certain aspects of the present disclosure provide techniques for receiver side protection in sidelink communications. In certain aspects, a method performed by an apparatus generally includes obtaining, from a first user equipment (UE), first control information, which includes a first resource allocation information of one or more resources allocated for transmission by the first UE to the apparatus and an indication of a first cell associated with the first UE. The method generally includes obtaining, from a second UE, second control information, which generally includes a second resource allocation information of resources allocated for transmission by the second UE to the apparatus and an indication of a second cell associated with the second UE. The method generally includes determining, based on the first and second control information, potential interference from transmissions by the first UE and the second UE and taking one or more actions to mitigate the potential interference.

Abstract: Methods, systems, and devices for wireless communications are described. To improve sidelink reservation schemes, a first user equipment (UE) may receive, from a second UE, a coordination message indicating a set of resources associated with sidelink communications and a preference of the second UE for one or more subsets of the set of resources. The first UE may transmit the sidelink communications using one or more resources of the set of resources based on the preference of the second UE for the one or more subsets of the set of resources. In some examples, the one or more resources may be selected from candidate resources within a resource selection window of the first UE. Additionally, or alternatively, the candidate resources may be based on the preference of the second UE.

Abstract: Certain aspects of the present disclosure provide techniques for multiplexing HARQ feedback in a same slot for downlink and sidelink transmissions. An example method generally includes receiving, from a network entity, a downlink control information (DCI) that schedules resources for at least one physical sidelink shared channel (PSSCH) transmission from the first UE to a second UE, transmitting data to the second UE via the at least one PSSCH transmission using the scheduled resources, receiving, from the second UE, acknowledgment feedback for the at least one PSSCH transmission, selecting at least one codebook entry for providing feedback for at least one downlink transmission from the network entity to the first UE and the acknowledgment feedback for the at least one PSSCH transmission in a same physical uplink control channel (PUCCH) slot, and transmitting the at least one codebook entry to the network entity via at least one PUCCH transmission.
