Abstract

A first communication device is configured to communicate with a second communication device and a third communication device in a wireless communication network using beamforming. The first communication device is configured to determine a new beam from a plurality of available beams of the second communication device in response to a beam failure event. The second communication device transmits a beam failure recovery request (BFRQ) message to the third communication device. The BFRQ message contains information about the new beam determined by the first communication device. The second communication device receives from the second communication device a BFRQ response message.
