Japanese Patent JP7283531

B2

Embodiments of the present disclosure provide method, device and computer readable medium for beam failure recovery. In example embodiments, a method implemented at a terminal device is provided. The method comprises, in response to a network device providing at least a primary cell (PCell) and a secondary cell (SCell) to serve the terminal device and a beam failure being detected in the SCell, determining, from the PCell and the SCell, a first cell in which a beam failure recovery (BFR) request is to be transmitted to the network device and a second cell in which a response to the BFR request is to be received from the network device. The method further comprises transmitting, in the first cell, the BFR request to the network device. In addition, the method further comprises monitoring a control channel search space in the second cell to receive the response to the BFR request from the network device.
