US Patent 11638319 Handling radio link failure in cellular mesh networks

Methods and apparatuses for handling radio link failure (RLF) in a wireless communication network. A method for operating a base station (BS) includes detecting occurrence of a RLF on a backhaul link with a parent BS of the BS and transmitting to a wireless communication device connected to the BS a first notification of the RLF indicating to hold data to be transmitted from the wireless communication device to the BS.
