Abstract: Embodiments of this application provide example beam failure recovery methods, example devices, and example systems to perform beam failure recovery. In one example method, a terminal device receives configuration information. The terminal device can determine M beam failure detection resource groups and N candidate beam resource groups based on the configuration information, where M and N are positive integers greater than 1. In response to determining that quality of each beam failure detection resource in any of the M beam failure detection resource groups is lower than a first threshold, the terminal device can determine, from a candidate beam resource group that is associated with the beam failure detection resource group and that is in the N candidate beam resource groups, one or more candidate beam resources whose quality is higher than a second threshold, and send first indication information.

Abstract: A timing advance obtaining method includes receiving, by a terminal device, first information from a network device. The first information indicates the terminal device to perform random access to a first cell, and the first cell is a non-serving cell of the terminal device. The method also includes sending, by the terminal device, a random access preamble corresponding to the first cell to the network device based on the first information. The method further includes receiving, by the terminal device, a random access response message from the network device. The random access response message includes a first timing advance corresponding to the first cell.
