Patent attributes
Aspects relate to techniques for joint communication-ranging (JCR) channel estimation. A first wireless communication device may transmit a sidelink message to a second wireless communication device and receive bistatic communication channel feedback from the second wireless communication device based on the sidelink message. The first wireless communication device may further transmit a ranging signal, such as a radar signal or lidar signal, and obtain a monostatic ranging channel estimate based on the received reflected ranging signals. The first wireless communication device may then associate and correlate the monostatic ranging channel estimate with the bistatic communication channel feedback to obtain joint communication-ranging (JCR) side information. The first wireless communication device may then transmit a sidelink transmission to the second wireless communication device using a transmit power and/or a beamforming parameter selected based on the JCR side information.
