Abstract: A first device may transmit an indication of a base graph recommendation. A second device may receive the indication of the base graph recommendation. The second device may select a base graph from a plurality of base graphs based on the base graph recommendation. The second device may transmit an indication of the selected base graph from the plurality of base graphs after the selection of the indication of the base graph recommendation. The first device may receive the indication of the selected base graph from the plurality of base graphs after an output of the indication of the base graph recommendation. The second device may transmit a low density parity check (LDPC) coded transmission based on the selected base graph. The first device may receive the LDPC coded transmission based on the selected base graph.

Abstract: A method of wireless communication at a first V2X device is described herein. The method includes obtaining a message including a MAC header, an L1 source ID, and an L1 destination ID. The method includes decoding the MAC header to produce an L2 source ID associated with the message based on at least one of (1) the L1 destination ID of the message matching a first number of bits of an L2 source ID of the first V2X device or (2) the L1 source ID of the message matching a second number of bits of the L2 source ID of the first V2X device. The method includes outputting an indication of a MAC cloning attack based on the L2 source ID of the message matching the L2 source ID of the first V2X device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from multiple UEs including a second UE, multiple sidelink control informations (SCIs). The UE may select, from multiple resource conflict indications derived from the multiple SCIs, a resource conflict indication based at least in part on a priority scheme. The UE may transmit, to at least one of the multiple UEs including the second UE, the resource conflict indication in accordance with a transmission power level. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) determines a candidate comb pattern associated with transmission of a sidelink positioning reference signal (SL-PRS) across multiple physical resource blocks (PRBs) that results in an unequal distribution of occupied resource elements (REs) per PRB, and determines that at least one rule associated with a set of rules is satisfied. The first UE transmits the SL-PRS to a second UE in accordance with the candidate comb pattern based on the at least one rule being satisfied. The second UE receives the SL-PRS and determines that the at least one rule is satisfied.

Abstract: In an aspect, a target sidelink user equipment may obtain at least one quality classification indication for each sidelink (SL) anchor device of a plurality of SL anchor devices for a positioning session, wherein the at least one quality classification indication is based on a quality of synchronization of the SL anchor device, a quality of timing of the SL anchor device, a quality of a position estimate for a location of the SL anchor device, or any combination thereof. The target sidelink user equipment may engage in the positioning session with or using one or more SL anchor devices of the plurality of SL anchor devices, wherein the one or more SL anchor devices are selected for the positioning session based on the at least one quality classification indication associated with each of the one or more SL anchor devices.

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 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.
