SIGNAL TRANSMISSION METHOD USING SPECTRUM SHARING MULTI-NUMEROLOGIES, AND ELECTRONIC DEVICE PERFORMING SAME

Title:

SIGNAL TRANSMISSION METHOD USING SPECTRUM SHARING MULTI-NUMEROLOGIES, AND ELECTRONIC DEVICE PERFORMING SAME

Document Type and Number:

WIPO Patent Application WO/2023/003149

Kind Code:

A1

Abstract:

A base station according to an embodiment may: acquire channel information about one or more terminals receiving, from the base station, signals for providing downlinks; generate, on the basis of the acquired channel information, a first precoding matrix for a first group using a first numerology; generate, on the basis of the first precoding matrix, signals to be transmitted via a plurality of antennas of the base station; and transmit the signals via the plurality of antennas. Various other embodiments may be possible.
