Document Type and Number:
WIPO Patent Application WO/2019/093025
Kind Code:
A1
Abstract:
[Problem] To make it possible to restore communication between a base station and a terminal device in a more appropriate manner. [Solution] A communication device provided with: a communication unit which performs wireless communication; and a notification unit which notifies a base station of information relating to a second beam usable in place of a first beam that is preferentially used in the wireless communication with the base station among a plurality of beams.
