Abstract: Methods, systems, and devices for wireless communications are described in which interference between wireless devices that employ radar detection may be reduced or mitigated. A user equipment (UE) may transmit radar signals for target detection and collision avoidance in accordance with an interference mitigation procedure. The interference mitigation procedure may be based on measurement reports of different UEs that are transmitted to a first node (e.g., a roadside unit (RSU) or base station). The first node may configure a measurement procedure for multiple UEs that includes multiple measurement stages, in which a first stage provides that a subset of UEs transmit while other UEs measure received radar signals, and a second stage switches the transmitting and measuring UEs. Each of the UEs may provide measurement reports to the first node, which determines coordinated transmit parameters for the UEs to reduce interference among the UEs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit signaling to a first network entity indicating a location of the UE and a measured reference signal receive power (RSRP). The UE may receive an indication of a time division duplex (TDD) configuration and a slot format indicator (SFI) for communications between the UE and the first network entity based on the RSRP or location. In some cases, the first network entity may receive signaling indicating a set of resource configurations from a second network entity. The first network entity may select a resource configuration (e.g., for communications with the UE) from the set based on a measured RSRP indicated by the UE or a location of the UE. The UE and the base station (e.g., the wireless device and the first network entity) may communicate according to the indicated or selected resource configurations.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may determine a set of resources available for transmission of one or more reference signals (e.g., one or more PRSs) in a shared radio frequency spectrum band (e.g., an unlicensed radio frequency spectrum band) in a time interval for sidelink positioning. The UE may transmit, in a second radio frequency spectrum, a control message reserving the set of resources for the UE to transmit the one or more reference signals in the time interval for sidelink positioning. The UE may transmit the one or more reference signals on the set of resources based on transmitting the control message reserving the set of resources.

Abstract: Apparatus, methods, and computer-readable media for sidelink control information forwarding for sensing procedure are disclosed herein. An example method of wireless communication at a forwarding user equipment (UE) includes receiving, from a forwarded UE, control information, and transmitting, to a sensing UE, a forward message including the control information and information associated with the forwarded UE. An example method of wireless communication at the sensing UE includes receiving, from the forwarding UE, a forward message including the control information containing a first measurement of the control information. The example method also includes obtaining a second measurement of the forward message and determining a ratio of the second measurement to the first measurement. The example method also includes selecting a specific resource based on the ratio and whether the forwarding UE is an intended receiver for the sensing UE or the forwarding UE intends to receive from the forwarded UE.

Abstract: Systems, methods, and devices for sidelink positioning determination and communication can employ techniques including obtaining, at a first sidelink-enabled device, data from one or more data sources indicative of one or more criteria for using either round-trip time (RTT)-based positioning of a target node or single-sided (SS)-based positioning of the target node. The techniques also include selecting, with the first sidelink-enabled device, a positioning type from the group may comprise of RTT-based positioning and SS-based positioning, based on the data. The techniques also include sending a message from the first sidelink-enabled device to a second sidelink-enabled device, where the message includes information indicative of the selected positioning type.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit, within an active duration of a first sidelink discontinuous reception (DRX) pattern of a second UE, sidelink control information (SCI) indicating a resource reservation for a sidelink resource of the sidelink channel within at least a portion of an inactive duration of the first sidelink DRX pattern. The first UE may then communicate, with the second UE via the sidelink channel, a sidelink message within the sidelink resource indicated in the resource reservation.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit a request for a base station to establish a wireless communication link between the first UE and a second UE via an assisting device (AD) associated with an assisting node (AN). The first UE may receive first control signaling from the base station including an indication for the first UE to perform a directional learning procedure with the AN in response to the request, and may transmit an uplink message including an indication of a completion of the directional learning procedure. The first UE may receive second control signaling from the base station indicating a set of resources for performing a link configuration procedure between the first UE and the second UE, and may communicate with the second UE via the AD of the AN based on the second control signaling.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a wireless device may support multi-band joint communication and radar (JCR) techniques. In some cases, a first wireless device may transmit, to a second wireless device, a capability message indicating whether a set of bands supports JCR operations. The second wireless device may transmit control signaling, based on the capability message, indicating a set of parameters for JCR operations including resources allocated for JCR operations. The first wireless device may transmit a JCR signal based on the control signaling via the allocated resources. For example, the first wireless device may transmit the signal for both communications and radar sensing in accordance with the set of parameters via the allocated resources.
