Abstract: A first user equipment (UE) receives sidelink resource reservation information over sidelink from one or more UEs. The first UE transmits inter-UE coordination information in a sidelink transmission based on a probability threshold being met. A wireless device may receive one or more of a status of a UE, a capability of the UE, or a report. The wireless device may configure the UE with a probability threshold for transmission of inter-UE coordination information in a sidelink transmission.

Abstract: A first UE and at least one second UE are disclosed. The first UE may identify one or more resources that are suitable for a subsequent transmission from at least one second UE. The first UE may transmit to the at least one second UE, an inter-UE coordination message and at least one data transmission. The inter-UE coordination message may be transmitted at a same time as the at least one data transmission. The inter-UE coordination message may include an indication of the one or more resources that are suitable for the subsequent transmission from the at least one second UE. In one configuration, the inter-UE coordination message may be piggybacked with the at least one data transmission. The at least one second UE may transmit the subsequent transmission via the one or more resources, or may reselect the one or more resources based on the inter-UE coordination message.

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: 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: 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: 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.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish multiple unicast connections with multiple other UEs. The first UE may then determine individual sets of transmission parameters for each of the multiple other UEs, where the individual sets of transmission parameters may enable the first UE to receive transmissions from the multiple other UEs on a same set of time and frequency resources via a spatial division multiplexing scheme. For example, each of the individual sets of transmission parameters may include a transmission schedule adjustment, a transmit power, a transmit time, an indication of the time and frequency resources, or a combination thereof. The first UE may then transmit each of the individual sets of transmission parameters to a respective UE of the multiple other UEs.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to measure self-interference between multiple transmission reception points (TRPs) of the UE and initiate sidelink full duplex communications based on the measured self-interference. The UE may transmit a message to a base station to request resources for sidelink communications by the UE and indicate an intended self-interference measurement by the UE using the resources. The base station may transmit a grant scheduling the resources for the self-interference measurement by the UE. The UE may measure interference between a TRP of the UE that is configured for transmission and a TRP of the UE that is configured for reception using the scheduled resources. The UE may transmit a sidelink feedback message indicating resources that are available for sidelink full duplex communications by the UE based on the measured self-interference.

Abstract: According to some aspects, a wireless device may indicate to another device a receive configuration indicator (RCI) to indicate a receive spatial configuration of the wireless device. For example, a first device may configure the first device to receive, from a second device, a signal using a first receive spatial configuration of the first device that corresponds to a first transmit spatial configuration of the second device. The first device may further determine a RCI to indicate the first receive spatial configuration of the first device, and may transmit the RCI to the second device.
