Title:

COMMUNICATION METHOD BASED ON SIMILARITY OF INTER-FREQUENCY BAND SPATIAL INFORMATION FOR CHANNEL IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

Document Type and Number:

WIPO Patent Application WO/2022/030664

Kind Code:

A1

Abstract:

Disclosed is a method for performing communication on the basis of the similarity of inter-frequency band spatial information for channel by a terminal having first information in a wireless communication system. A method according to an embodiment of the present specification comprises the steps of: receiving second information from a base station; when the calculation capability of the base station related to the similarity of spatial information for channel is identified on the basis of at least one of the first information and the second information, requesting calculation of the similarity from the base station; and when receiving a response to the request, performing at least one of beam training and channel estimation on the basis of the response. A terminal of the present specification may be linked to an artificial intelligence module, a drone (unmanned aerial vehicle (UAV)), a robot, an augmented reality (AR) device, a virtual reality (VR) device, a device related to a 6G service, and the like.
