Abstract: A multimode apparatus and a communication method thereof are disclosed. If the multimode apparatus is chosen to serve as a relay station due to a base station having a backhaul link problem, it sets up a first relay link with a first base station. Upon receiving a request for releasing the first relay link from the first base station even though the backhaul link is not restored, the multimode apparatus sets up a second relay link with a second base station, or configures and operates a standalone network or an independent network.

Abstract: A communication method of a terminal that can operate in a relay mode or a base station mode is provided. When the terminal, having received a service from a first base station, detects that a service connection to the first base station is unavailable, the terminal searches for a second base station, which is an available neighboring base station. The terminal transmits a ranging request message including a base station identifier of the first base station to the second base station.
