Title:
APPARATUS AND METHOD FOR PERFORMING RADAR-COMMUNICATION BY USING VIRTUAL RECEIVE ARRAY IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/111693
Kind Code:
A1
Abstract:
The present disclosure is for performing radar-communication by using frequency hopping in a wireless communication system, and an operating method of a communication apparatus may comprise the steps of: generating at least one codeword by encoding information bits; generating modulation symbols on the basis of the at least one codeword; transmitting signals including the modulation symbols; and when the signals are received after being reflected at an object, performing a radar operation by using the received signals. The radar operation may be performed on the basis of a virtual receive array formed by using signals transmitted through at least one subarray operating in a transmitting mode and received through the remaining at least one subarray operating in a receiving mode, from among a plurality of subarrays included in an antenna array, during a plurality of time intervals.
