Disclosed are techniques for signaling of sensing target modeling information. In an aspect, a receiver sensing node receives, from a sensing entity via one or more transceivers, assistance data for sensing a set of target objects, the assistance data comprising target modeling information for each target object of the set of target objects, obtains a plurality of sensing measurements of one or more sensing reference signals transmitted by a transmitter sensing node and reflected from at least a subset of target objects of the set of target objects, and assigns one or more sensing measurements of the plurality of sensing measurements to each target object in the subset of target objects based at least in part on the target modeling information for each target object of the set of target objects.

A communication method and apparatus are applied to a wireless local area network system that supports IEEE 802.11ax (Wi-Fi 6)/802.11be (Wi-Fi 7)/802.11bn (Wi-Fi 8)/Wi-Fi AI/millimeter wave/ultra-wideband UWB, or sensing, to reduce overheads of a sensing receiver feeding back a CIR tap based on a predefined feedback pattern. A sensing transmitter may send first information including a first parameter and a second parameter. The first parameter is of a first value, the first parameter indicates that the sensing receiver feeds back a CIR tap based on the predefined feedback pattern, and the second parameter indicates a quantity of CIR taps that need to be fed back in each CIR group.

A method for designing a time-domain non-stationary V2V MIMO communication channel emulator includes determining basic parameters for the V2V MIMO communication channel; generating a V2V 2D time-domain non-stationary communication channel environment, by using a MATLAB, that is, the numbers of the scatterers and the positions of the scatterers and the like; importing parameters generated in the previous step into a hardware simulation platform to calculate communication channel parameters for clusters, such as an angle distribution and a power distribution, writing a Verilog code for running, and eventually calculating to obtain a channel impulse response of the time-domain non-stationary V2V MIMO communication channel; and comparing with a statistical characteristic of a theoretical communication channel model, and designing an appropriate hardware diagram of a communication channel emulator. The method supports the simulation of time-domain non-stationary V2V MIMO communication channel, filling the gap in the field of communication channel emulators.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first indication of a set of analog receive beams and an instruction to report one or more post-analog-beamformed channel impulse responses (CIRs) that are based at least in part on the set of analog receive beams. The UE may transmit a second indication of a CIR report that indicates the one or more post-analog-beamformed CIRs. Numerous other aspects are described.

A method for processing a RF signal. The method includes receiving the signal having a sequence of chips, sampling the signal to generate a sampled signal, generating, based on the sequence of chips, a cancellation signal, subtracting the cancellation signal from the sampled signal to generate a cancelled signal, and performing an accumulation based on the cancelled signal to generate a channel impulse response (CIR) estimation.
