Abstract: Disclosed are techniques for wireless positioning. In an aspect, a road-side unit (RSU) may join a first sidelink (SL) ranging session between a first user equipment (UE) and a second UE. The RSU may perform SL ranging with the first UE to determine first ranging information comprising at least a RTT to the first UE. The RSU may perform SL ranging with the second UE to determine second ranging information comprising at least a RTT to the second UE. The RSU may send the first ranging information and the second ranging information to at least one of the first UE or the second UE, or calculate a range between the first UE and the second UE based on the first ranging information and the second ranging information, and send the range to at least one of the first UE and the second UE.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a base station may receive, from a first user equipment (UE), an uplink message that includes one or more sidelink communication identifications each associated with a different UE of a set of one or more UEs and may associate each of the one or more sidelink communication identifications with a corresponding second identification also associated with each of the set of one or more UEs. The base station may transmit one or more signals for transitioning each of the set of one or more UEs associated with the set of second identifications from an inactive mode to an active mode based on associating each of the set of one or more sidelink communication identifications with the second identification of the set of second identifications. A second UE may receive, while in the inactive mode from the base station, the one or more signals that trigger the transition and may communicate with the first UE based on receiving the wake-up signal.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be associated with a reconfigurable surface for reflecting transmissions between second and third UEs (e.g., over sidelink resources). In one example, the first UE may transmit signaling indicating that retransmissions of a first message transmitted between a second and third UE and detected by the first UE may be reflected by the reconfigurable surface associated with the first UE. In another example, the first UE may receive a request from a second UE for signal enhancement using a reconfigurable surface, the request associated with a future transmission by the second UE to a third UE. In either case, the UE may determine to perform signal enhancement using a reconfigurable surface and may then reconfigure the reconfigurable surface for reflecting transmissions or retransmissions from the second UE to the third UE.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive an indication of one or more parameters for communications over a sidelink channel during a first time period, where the one or more parameters may include a time threshold for a second resource pool. The wireless device may transmit data over a first resource pool of the sidelink channel during a first portion of the first time period based on the one or more parameters, the first resource pool including resources for communications between the first wireless device and a second wireless device. The wireless device may monitor the second resource pool during a second portion of the first time period for the time threshold, the second resource pool including resources for communications between the first wireless device and a third wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit concurrent messages over a sidelink channel to another UE and over an uplink channel to a base station. The UE may transmit, to a base station, a report indicating a capability of the UE to concurrently transmit over a sidelink channel and an uplink channel. The UE may receive, from the base station and based on the report, a transmission configuration scheduling a concurrent sidelink and uplink transmission within a resource shared by the sidelink channel and the uplink channel. The UE may then transmit the concurrent sidelink and uplink transmission within the resource shared by the sidelink channel and the uplink channel based on the transmission configuration. The other UE and the base station may receive the concurrent sidelink and uplink transmission and may decode different layers of the transmission.

Abstract: In a particular implementation, a method of wireless communication includes transmitting, from a first user equipment (UE) to a second UE, a radio resource control (RRC) request that includes a first discontinuous reception (DRX) preference at the first UE. The method also includes receiving, at the first UE from the second UE, a RRC setup message that includes a second DRX preference at the second UE. The method further includes transmitting, from the first UE to the second UE, a RRC setup complete message that includes an indication of a confirmed DRX cycle.

Abstract: Methods, systems, and devices for wireless communications are described. A roadside unit (RSU) may transmit, to a first communication node, a request for multi-static sensing capability information associated with the first communication node. The RSU may receive a report indicating the multi-static sensing capability information for the first communication node. The RSU may transmit, in response to receiving the multi-static sensing capability information, a control message indicating one or more multi-static sensing parameters for the first communication node. The RSU may receive one or more multi-static sensing measurements obtained based at least in part on the one or more multi-static sensing parameters. The RSU may transmit, to the first communication node, a second communication node, or both, one or more channel estimates determined based at least in part on the one or more multi-static sensing measurements.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) or a base station may communicate a set of reference signals on a set of interference measurement resources. The set of interference measurements may be based on a first activation schedule of one or more reconfigurable intelligent surfaces (RISs). The UE or the base station may generate interference measurement information associated with the one or more RISs based on the set of reference signals. The base station may determine a second activation schedule of the one or more RISs or an allocation of resources for communicating with the UE based on the set of interference measurements. The base station may communicate with the UE based on the second activation schedule or the allocation of resources.
