Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, in a first slot within a channel occupancy time (COT), a first communication; determine whether one or more transmission criteria are satisfied for transmission of a second communication in a second slot within the COT; and selectively transmit the second communication in the second slot within the COT based at least in part on a result of determining whether the one or more transmission criteria are satisfied. Numerous other aspects are provided.

Abstract: Aspects relate to group-based reference signal broadcast in a wireless communication network. A first wireless communication device may transmit a first group formation broadcast message associated with a first positioning group comprising a first plurality of wireless communication devices including the first wireless communication device. The first wireless communication device may receive a second group formation broadcast message associated with a second positioning group comprising a second plurality of wireless communication devices including a second wireless communication device. The second positioning group may be associated with a channel occupancy time (CoT) in a sidelink channel. The CoT may comprise transmission opportunities configured to be used by the second plurality of wireless communication devices for communicating reference signals. The first wireless communication device may initiate transmission of reference signals by the first plurality of wireless communication devices using additional transmission opportunities within the CoT associated with the second positioning group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may transmit, to a receiver UE, a first communication that includes a positioning reference signal (PRS) associated with the transmitter UE. The UE may transmit, to the receiver UE, a second communication that includes an information element associated with a boundary of a vehicle associated with the transmitter UE. Numerous other aspects are described.

Abstract: Aspects relate to techniques for enabling a UE to detect a potential mistrusted UE that may be sharing inaccurate sidelink assistance information with other UEs. In an aspect, a first UE may receive a plurality of sidelink assistance information from other UEs. The first UE can further identify an amount of the plurality of sidelink resources for which a second UE provides respective inconsistent sidelink assistance information with respect to other UEs. In response to the amount exceeding a mistrust detection threshold, the first UE can transmit a report indicating that the second UE is a potential mistrusted UE to a centralized node. Based on the received reports associated with the second UE, the centralized node can transmit a mistrust indication indicating that the second UE is an actual mistrusted UE with respect to subsequent sidelink assistance information associated with the second UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on an access link from a base station, a first downlink control information (DCI) that schedules a first communication on a physical sidelink shared channel (PSSCH) and a second DCI that schedules a second communication on the PSSCH. The first communication and the second communication may be scheduled according to a rule for overlapping or ordering communications on the PSSCH that are associated with one or more hybrid automatic repeat request identifiers. The UE may transmit the first communication and the second communication as scheduled. 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: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable mediums for determining timing advances (TAs) for use in sidelink (SL) communications. A method that may be performed by a receiver (RX) user equipment (UE) includes receiving, from a network entity, an indication of a TA for SL communications with a first transmitter (TX) UE and applying the indicated TA when receiving at least one SL transmission from the first TX UE.

Abstract: Certain aspects of the present disclosure provide techniques for enhanced resource reservation for sidelink communication. A method that may be performed by a transmitter user equipment (UE) includes transmitting a transport block (TB) in a first slot of a current reservation period, wherein the transmission of the TB reserves a future resource in the current reservation period for retransmission of the TB, indicating, when transmitting the TB, a period to periodically reserve one or more resources, in one or more future reservation periods, for transmissions of one or more other TBs, and taking action to limit or release a number of the one or more resources periodically reserved in the one or more future reservation periods for the transmissions of the one or more other TBs.
