Title:
RECEPTION DEVICE COMPRISING LINEAR COUPLER IN MIMO SYSTEM FOR SUPPORTING MULTI-NUMEROLOGY, AND OPERATING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/019341
Kind Code:
A1
Abstract:
A reception device is disclosed. One embodiment comprises: a plurality of antennas; an RF communication circuit which receives transmission signals from transmission devices through the antennas, and which processes the received transmission signals so as to acquire digital signals; and a processor, which processes each of the acquired digital signals so as to generate frequency domain signals, arranges the generated frequency domain signals on the basis of an index of subcarriers of a first numerology from among a plurality of numerologies, selects some channels between a reception device and a second transmission device using a second numerology, determines valid channel matrices by using a first channel matrix and a second channel matrix for each of the subcarriers, and performs linear coupling on each of the arranged frequency domain signals on the basis of each of the determined valid channel matrices so as to detect data streams of a first transmission device.
