Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., sidelink systems, such as vehicle-to-everything (V2X) systems), wireless devices may perform dynamic resource reservations to schedule packet transmissions (e.g., data packet transmissions). Different packets may correspond to different priority levels. To support flexible resource reservation for high priority packets, wireless devices may implement techniques for preempting lower priority reservations. For example, a wireless device may identify reservations for transmitting different packets during a same transmission time interval (TTI). The device may determine whether a first or second packet has a higher relative priority and may communicate in the V2X system during the TTI according to the relative priorities. For example, a device that reserved the TTI for the lower priority packet may refrain from transmitting the packet during the TTI, while a device that reserved the TTI for the higher priority packet may transmit the packet.

Abstract: Aspects directed towards network-assisted sidelink scheduling are disclosed. In one example, a scheduled entity receives coverage status information of a peer user equipment (UE), and transmits a coverage status report to a network in which the coverage status report is based on the coverage status information received from the peer UE. The scheduled entity receives a resource scheduling from the network in response to transmitting the coverage status report, and establishes a sidelink communication with the peer UE based on the resource scheduling. In another example, a scheduling entity receives a coverage status report from a UE in which the coverage status report is associated with a peer UE of the UE. The scheduling entity determines a resource scheduling for the UE based on the coverage status report to facilitate a sidelink communication between the UE and the peer UE, and transmits the resource scheduling to the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive an indication of a configuration of one or more communication links associated with an enhanced duplex mode of at least one of the first wireless node or a second wireless node. The first wireless node may receive an indication of a random access channel (RACH) configuration associated with the second wireless node. The first wireless node may transmit a request to modify the RACH configuration, where the request to modify the RACH configuration is based at least in part on the configuration of the one or more communication links and the RACH configuration. Numerous other aspects are provided.

Abstract: In an aspect, an initiator transmits a positioning reference signal. The initiator receives a plurality of responder positioning reference signals sent from individual responders of a plurality of responders. The initiator transmits a measurement message comprising a first set of measurements that are determined based on the positioning reference signal and the plurality of responder positioning reference signals. The initiator receives responder measurement messages sent from the individual responders of the plurality of responders. The initiator receives updated map information from an anchor and updates pre-existing map information based on the updated map information.

Abstract: An apparatus may comprise a component for communicating using a first RAT and another component for communicating using a second RAT. Overlapping communication using the two RATs may cause problems for proper reception at the apparatus. The apparatus may detect that transmission or reception of a first packet using a first RAT will overlap in time with reception of a second packet using a second RAT. The apparatus prioritizes the first packet or the second packet based at least on a relative priority of the first packet and the second packet.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving (Rx) user equipment (UE) may receive, from a transmitting (Tx) UE, sidelink control information (SCI). The Rx UE may determine an Rx-side block error rate (BLER) based at least in part on the SCI. The Rx UE may perform a beam failure recovery based at least in part on the Rx-side BLER satisfying a threshold. Numerous other aspects are described.

Abstract: A configuration to enable a UE operating as a full duplex device to transmit or receive feedback to or from other full duplex wireless devices or half duplex wireless devices. The apparatus allocates one or more sets of feedback resources, in association with a second UE, for transmission or reception of feedback message. The apparatus determines to transmit or receive the feedback message on a first resource set of the one or more sets of feedback resources based on a priority of the feedback message or a priority of a feedback resource set to transmit or receive a feedback message. The apparatus transmits or receives the feedback message based on the priority of the feedback message or the feedback resource set.

Abstract: Multiple user equipments (UEs) may initiate independent ranging sessions at nearly the same time and location and which may interfere with each other. A UE that receives multiple initial messages for ranging determines if there is temporal separation between the ranging sessions. The UE may further determine if there is geographic separation between the ranging sessions, e.g., the initiating UEs are separated. If separation is lacking, the UE separates available ranging signal properties, such as frequency bandwidth, timing instances, and identifiers, and communicates different sets of ranging signal properties to each initiating UE. The multiple ranging sessions may be performed using the different sets of ranging signal properties with less risk of interference.

Abstract: A first UE may determine to communicate with a second UE, but may maintain or establish a RRC connection with a third UE upon determining that potential interference may occur between the first UE and the third UE. The potential inference may be a received interference in which the first UE receives interference from the third UE as a result of a communication between the third UE and a fourth UE, or a transmitted interference in which the first UE causes interference to the third UE as a result of a communication between the first UE and the second UE. The first UE may communicate mitigation information to the third UE through the RRC connection, where the interference mitigation information may be associated with the communication between the first UE and the second UE or the communication between the third UE and the fourth UE.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for beam training resource selection by a sidelink UE. A first UE may determine to perform beam training with a second UE in a set of beam training resources. The set of beam training resources may include a first subset of beam training resources for UEs without a RRC connection and a second subset of beam training resources for UEs with a RRC connection, where the first subset of beam training resources and the second subset of beam training resources are non-overlapping. The first UE may determine whether the first UE is RRC connected with the second UE and perform beam training in one of the first subset of beam training resources or the second subset of beam training resources based on whether the first UE is RRC connected with the second UE.
