Methods and devices for monitoring a radio link quality
A user terminal includes a control section that, in a case where a maximum number of secondary cells to which a beam failure recovery is applied is 1 and where a specific secondary cell for an uplink control channel is configured, applies the beam failure recovery to the specific secondary cell, and a transmitting section that transmits, in the beam failure recovery, a beam failure recovery request to one of a plurality of cells. According to one aspect of the present disclosure, a BFR procedure can be appropriately executed.
1. A terminal comprising:
a processor that controls beam failure recovery based on whether or not a certain secondary cell for an uplink control channel is configured; and
a transmitter that transmits a beam failure recovery request to one of a plurality of cells in the beam failure recovery,
wherein the processor determines a maximum number of secondary cells to which the beam failure recovery is applied, based on a transmitted type among a plurality of types of the beam failure recovery request, and
wherein the processor controls the beam failure recovery based on the maximum number of secondary cells to which the beam failure recovery is applied.
2. The terminal according to claim 1 , wherein the transmitter reports capability information including the maximum number.
3. A radio communication method for a terminal, comprising:
controlling beam failure recovery based on whether or not a certain secondary cell for an uplink control channel is configured;
transmitting a beam failure recovery request to one of a plurality of cells in the beam failure recovery;
determining a maximum number of secondary cells to which the beam failure recovery is applied, based on a transmitted type among a plurality of types of the beam failure recovery request; and
controlling the beam failure recovery based on the maximum number of secondary cells to which the beam failure recovery is applied.
4. A system comprising a terminal and a base station, wherein
the terminal comprises:
a processor that controls beam failure recovery based on whether or not a certain secondary cell for an uplink control channel is configured; and
a transmitter that transmits a beam failure recovery request to one of a plurality of cells in the beam failure recovery,
wherein the processor determines a maximum number of secondary cells to which the beam failure recovery is applied, based on a transmitted type among a plurality of types of the beam failure recovery request, and
wherein the processor controls the beam failure recovery based on the maximum number of secondary cells to which the beam failure recovery is applied, and
the base station comprises:
a processor that determines whether or not the certain secondary cell is configured; and
a receiver that receives the beam failure recovery request.
