    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: 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.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication and radar detection. In some aspects, a radar device may perform, at an initial listen before talk (LBT) frame boundary associated with an initial LBT frame of a plurality of LBT frames, an initial LBT procedure, wherein the initial LBT frame has a frame length that is larger than a propagation delay associated with a maximum detectable range associated with the radar device; and transmit a radar signal based at least in part on a successful result of the initial LBT procedure or an additional LBT procedure. Numerous other aspects are provided.

    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.
