Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless communication device may transmit control information over one or more physical sidelink control channel (PSCCH) resources to a peer wireless communication device, wherein the control information includes sidelink positioning reference signal (SL-PRS) configuration information. The wireless communication device may transmit SL-PRS over one or more SL-PRS resources indicated by the SL-PRS configuration information to the peer wireless communication device, wherein, based on the one or more PSCCH resources and the one or more SL-PRS resources scheduled in a sidelink slot, transmission of the control information the one or more PSCCH resources and transmission of the SL-PRS over the one or more SL-PRS resources are separated in a time domain by at least a minimum time gap.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects are directed to enabling co-channel coexistence among UEs. Some aspects may mitigate or prevent collisions between sidelink transmissions, such as collisions between a New Radio (NR) physical sidelink feedback channel (PSFCH) and a Long Term Evolution (LTE) physical sidelink shared channel (PSSCH). Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, by a first radio access technology (RAT) sidelink module from a second RAT sidelink module, second RAT sidelink reservation information, the second RAT sidelink reservation information indicating a reference signal received power (RSRP) value. The first UE may perform, using the first RAT sidelink module, a first RAT sidelink resource selection based at least in part on the RSRP value indicated in the second RAT sidelink reservation information, wherein the first RAT sidelink resource selection is based at least in part on an exclusion or an inclusion of one or more single slot resources in a non-first-RAT-PSFCH slot or in a first RAT physical sidelink feedback channel (PSFCH) slot. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for acknowledgment feedback for groupcast option 1 sidelink communication are disclosed herein. An example method of wireless communication at a receiving user equipment (UE) includes determining whether a data signal associated with a groupcast transmission from a transmitting UE is decodable at the receiving UE and obtaining measurements of the data signal when the data signal is decodable at the receiving UE. The example method also includes determining whether the measurements exceed a threshold and transmitting a first type of feedback to the transmitting UE when the measurements do not exceed the threshold. An example method of wireless communication at a transmitting UE includes receiving, from a receiving UE over a sidelink channel, feedback comprising the first type of feedback when the first UE is determined to monitor for the first type of feedback and a second type of feedback from a plurality of UEs.

Abstract: Aspects presented herein may enable a UE to transmit or broadcast inter-UE coordination information to one or more UEs based on a set of dedicated-resources or a set of non-dedicated resources. In one aspect, a first UE configures one or more resources in a set of dedicated resources or in a set of non-dedicated resources for a transmission of an inter-UE coordination message, the inter-UE coordination message being associated with at least one of a first stage SCI format or a second stage SCI format. The first UE transmits the inter-UE coordination message via the one or more resources in the set of dedicated resources or in the set of non-dedicated resources.
