摘要： This disclosure relates to wireless radio link recovery methods. In various implementations, the method includes determining a beam failure event for a first cell, and transmitting a beam recovery request message on a shared uplink channel when available. In other implementations, the method includes determining that the shared uplink channel is not available for transmitting the beam recovery request message and transmitting a resource request to request allocation of the shared uplink channel via a second cell.
