Abstract: Certain aspects of the present disclosure provide techniques for device-to-device sidelink collision indication (s) based on distance-based conditions. An example method performed by a user equipment (UE) generally includes receiving resource reservation information indicating reservations of resources by at least a second UE and a third UE; and transmitting a collision indication to at least one of the second UE or the third UE when the resource reservation information indicates colliding transmissions and at least one distance-based condition is met.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) determines that a perception-based approach to adaptive beam weight learning would provide improved performance of wireless communication with a base station over a wireless communication medium relative to non-perception-based approaches to adaptive beam weight learning, and transmits, to a network node, an indication for the base station to perform perception-based adaptive beam weight learning procedures for the wireless communication with the base station over the wireless communication medium.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes identifying a feedback channel configuration that maps a set of multiple subchannels of a sidelink channel to a set of multiple feedback resources of a feedback channel of the sidelink channel, receiving control signaling scheduling the full duplex UE to transmit or receive a first sidelink message in a first subchannel of the set of multiple subchannels, assigning a first feedback resource of the set of multiple feedback resources for transmission or reception of feedback for the first sidelink message that differs from a default resource identified by the feedback channel configuration, and communicating feedback data for the first sidelink message in the first feedback resource of the feedback channel based on the assigning.

Abstract: Disclosed are techniques for using ranging signals to determine a position of a pedestrian user equipment (P-UE). In an aspect, a UE receives a plurality of ranging signals transmitted by one or more UEs, measures one or more properties of each of the plurality of ranging signals, and calculates an estimate of the position of the P-UE based on the one or more properties of each of the plurality of ranging signals. In an aspect, the P-UE transmits a plurality of ranging signals, receives a first message and a second message from first and second vehicle UEs (V-UEs), the first and second messages including first and second estimated positions of the P-UE and associated first and second confidences, and calculates an estimate of the position of the P-UE based on the first estimated position, the first confidence, the second estimated position, the second confidence, or a combination thereof.

Abstract: Apparatus, methods, and computer-readable media for facilitating sidelink carrier aggregation with cross-carrier feedback are disclosed herein. An example method for wireless communication at a first wireless device includes receiving, from a second wireless device, a first sidelink message including a first transport block (TB) on a first carrier. The example method also includes generating a first Hybrid Automatic Repeat Request (HARQ) feedback for the first TB. The example method also includes determining a first feedback carrier to transmit cross-carrier feedback. The example method also includes mapping the first HARQ feedback for the first TB to the first feedback carrier, the first feedback carrier being different than the first carrier. The example method also includes transmitting the first HARQ feedback on the first feedback carrier to the second wireless device.

Abstract: Aspects of the present disclosure describe indicating per-packet quality of service (QoS) in communications by a wireless communications device. A packet from an application generated for a first radio access technology (RAT) can be obtained, where the packet includes a first QoS value associated with the first RAT, and/or the first QoS value can be mapped to a second QoS value associated with the second RAT. In another example, the QoS value can be indicated in the packet along with a reflective indicator indicating to use the QoS value in transmitting a response to the packet.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, information related to a concurrent reception capability using different receive beams. The UE may receive, from the base station, information indicating one or more slots in which concurrent sidelink and downlink reception is enabled based at least in part on the information related to the concurrent reception capability. The UE may receive, in the one or more slots in which concurrent sidelink and downlink reception is enabled, a downlink transmission from the base station using a first receive beam and a sidelink transmission from a peer UE using a second receive beam. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a first user equipment (UE) to establish a communication link with a base station and a sidelink communication link with a second UE using different transmission reception points associated with the first UE. The first UE may perform an interference measurement between downlink communications received on the communication link and sidelink communications transmitted on the sidelink communication link. The first UE may determine whether it is able to perform full-duplex operations on the communication link and the sidelink communication link based on the interference measurement and may transmit an indication of the capability of the first UE to the base station. In some examples, the second UE may perform measurements of interference from downlink signals on the sidelink communication link, where the measurements may inform the determination to use full-duplex communications at the first UE.
