摘要： 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.

摘要： 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.

摘要： Methods, systems, and devices for wireless communications are described. A base station may identify a first radio bearer to be used for sensing operations and a second radio bearer to be used for data communications. The base station may transmit, to a user equipment (UE), a control message indicating the first radio bearer and the second radio bearer, where the first radio bearer and the second radio bearer may be indicative of a resource allocation for the sensing operations and the data communications. The UE may perform the sensing operations in accordance with a resource allocation, and perform the data communications in accordance with the resource allocation, where the resource allocation may be based on the first radio bearer and the second radio bearer. The UE may perform the sensing operations and the data communications in accordance with a joint communication and radar (JCR) system.

摘要： A method of wireless communication by a first user equipment (UE) includes requesting multi-static channel sensing estimates from a device to establish a communications link with a second UE, and receiving the multi-static channel sensing estimates from the device. The method further includes setting communication parameters based on the multi-static channel sensing estimates. The method still further includes communicating with the second UE over the communications link based on the communication parameters.

摘要： This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for assisted mmW sidelink beam discovery in non-standalone mode. A UE may transmit, to an AN, a request to access one or more ADs. The request may be based on an absence of at least one BPL that has a threshold QoS for a DRB with a second UE. The UE may receive, from the AN based on the transmitted request, an authorization to access the one or more ADs, and exchange, via an SRB, beam training information with the second UE based on the authorization to access the one or more ADs for performing a beam training procedure via the one or more ADs.

摘要： A method of wireless communication by a first user equipment (UE) includes receiving a vehicle-to-everything (V2X) message from a second UE. The method also includes periodically transmitting and receiving a radar signal to sense an environment of the first UE. The method includes estimating joint communication and radar side information based on the V2X message and the radar signal. The method further includes predicting a communication state between the first UE and the second UE based on the joint communication and radar side information. The method still further includes updating communication transmit parameters based on the communication state.

摘要： Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a first device may receive a feedback message from a second device that indicates a set of one or more sensing results associated with a sensing procedure performed by the second device. The first device may transmit, to the second device, a control message indicating resource information for a message for the second device. The control message may include an indication of a transmission configuration indication (TCI) state indicating a quasi-colocation (QCL) relationship between a reference signal associated with the message and a sensing result of the set of one or more sensing results indicated by the feedback message. The first device may transmit the message using a transmit beam and the second device may receive the message using a receive beam based on the TCI state and the QCL relationship.

摘要： Methods, systems, and devices for wireless communication are described. A communication device (e.g., a vehicle) in wireless communications system (e.g., a cellular-vehicle-to-everything (V2X) system) may support adaptive radar transmissions based on information received in a public safety message. The communication device may use information included in the public safety message to adapt radar transmissions to enable timely detection of vulnerable road users (VRUs). In some examples, based on a location and a velocity estimate provided in the public safety message, the communication device may adjust the radar transmissions to experience a trade-off between range and velocity estimation performance. Additionally or alternatively, based on positional accuracy estimates provided in the public safety message, the communication device may adjust the radar transmissions to improve beamforming. By adapting the radar transmissions, the communication device may experience low latency and high reliability for VRU collision warnings in the C-V2X system.

摘要： 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.
