Abstract:
This disclosure relates to techniques for performing beam failure recovery in a high speed single frequency network scenario in a wireless communication system. A wireless device may establish a cellular link with a cellular network according to a single frequency network scheme. The wireless device may determine one or more beam failure detection resources for each of multiple transmission reception points associated with the cellular network. The wireless device may detect beam failure for one or more of the transmission reception points using the beam failure detection resources.
