Abstract
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.
