USER TERMINAL AND RADIO COMMUNICATION METHOD Russian patent published in 2022 - IPC H04W24/04 H04W16/28 H04W74/08

Abstract RU 2780806 C2

FIELD: wireless communication.

SUBSTANCE: based on the act of failure of a beam received from a physical layer, a terminal control section increments a counter of beam failure acts in an overlying layer. Based on a command for transmission from the specified overlying layer, when the counter of beam failure acts exceeds the set threshold value or is equal to it, a transmission section transmits random access preambles. In the absence of a response to the random access preamble during a set response window period, the specified random access preamble is repeatedly transmitted.

EFFECT: provision of restoration after beam failure.
