Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a first user equipment (UE). The first UE selects one or more inter-UE coordination information messages based on at least one prioritization rule. The first UE then transmits the selected one or more inter-UE coordination information messages to at least a second UE via a sidelink.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, on one or more sidelink channels, a set of messages indicating a corresponding set of resource reservations. Accordingly, the first UE may transmit, to a second UE, a resource information message that indicates a subset of the set of resource reservations. The first UE may select the subset, from the set of resource reservations, using a time window, a maximum quantity of resource reservations, a retransmission threshold, a hop count threshold, a resource/subchannel threshold, or a combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first vehicle-to-every thing (V2X) device may receive, via a first radio access network (RAN), a scheduling assignment for a second V2X device. The first V2X device may decode the scheduling assignment to determine resource reservation information for the second V2X device on the first RAN. The first V2X device may modify at least one transmission associated with a second RAN based at least in part on the resource reservation information for the second V2X device on the first RAN. In some aspects, the first V2X device may transmit a coordination message for reception by one or more other V2X devices associated with a second RAN. The coordination message may include the resource reservation information for the second V2X device associated with the first RAN. Numerous other aspects are described.

Abstract: Embodiments include systems and methods for sidelink communications. In embodiments, a processor of a wireless device may determine signal strength information and priority information associated with a sidelink communication resource. The processor may determine coordination information based on the determined signal strength information and priority information. The processor may generate a message to include the determined coordination information. The processor may transmit the generated message including the determined coordination information to a second wireless device. In some embodiments, the generated message may be a control message, such as a medium access control control-element (MAC-CE) or a sidelink control information message.

Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.

Abstract: Methods, systems, and devices for wireless communications are described, in which a user equipment (UE) may communicate with one or more other UEs using sidelink communications. Multiple UEs may form a sidelink communications group and provide for sidelink groupcast communications in which an identification of a UE is determined based at least in part on a member identification of the UE within the group. Each UE in the group may determine feedback resources for acknowledgment feedback within the group based on a UE identification and a size of the group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform sensing in a sidelink resource pool. The UE may select, based at least in part on the sensing, one or more sidelink resources for one or more sidelink beam management blocks, where each sidelink beam management block includes at least one reference signal and sidelink control information. The UE may transmit the one or more sidelink beam management blocks in a sidelink beam management block burst using the one or more sidelink resources. Numerous other aspects are described.

Abstract: Aspects are provided which allow a UE to achieve sidelink parameter coordination through various signaling in clustered FL or peer-to-peer FL. The UE provides a first ML model information update and a measurement associated with the update. The UE obtains an aggregated ML model information update aggregating the first update with a second ML model information update of either a first network node in a FL cluster including the UE or a second network node in a second FL cluster. The UE provides a sidelink communication parameter in SCI to a network node, which parameter is an output of an ML model associated with the aggregated ML model information update. As a result, UEs may derive common SCI parameters from their updated ML models to apply in sidelink communications, thereby leading to maximized packet reception rate, maximized throughput, or minimized latency in communication.

Abstract: Aspects relate to group-based positioning reference signal (PRS) broadcast in a wireless communication network. Wireless communication devices communicating over a sidelink channel in the wireless communication network may be grouped into one or more positioning groups. Within each positioning group, a respective order of the wireless communication devices in the positioning group may be identified. The wireless communication devices in a positioning group may then communicate PRSs therebetween over the sidelink channel based on the order of wireless communication devices in the positioning group.
