Title:
TERMINAL AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/029066
Kind Code:
A1
Abstract:
One embodiment of this terminal has: a control unit that controls detection of a beam failure; and a transmission unit that uses a MAC control element to transmit information relating to the cell that detected the beam failure and to a new candidate beam, the format of the MAC control element having a first field that indicates at least the presence or absence of detection of the beam failure for each cell, and a second field that indicates information relating to the new candidate beam of the cell in which the beam failure was detected.
