Abstract: A method of controlling a base station is disclosed that provides service to a first terminal and a second terminal having higher priority than the first terminal. The base station determines whether there is an influx of call connection attempts when the lower-priority terminal and the higher-priority terminal perform ranging. If it is determined that there is an influx of call connection attempts, the base station sets the initial ranging backoff window size included in an information element of S-SFH SP3 (Secondary-Superframe Header SubPacket3) to a first size. If it is determined that there is an influx of call connection attempts, the base station sets the initial ranging backoff window size for the second terminal in an AAI-SCD (Advanced Air Interface-System Configuration Descriptor) message to a second size. Accordingly, it is possible to achieve a high probability of success of initial ranging of a higher-priority terminal.

Abstract: A permutated channel structure based on a block structure in talk-around direct communication is provided. A dedicated subchannel interferes with only one adjacent dedicated subchannel, even with a large synchronization error, by permutating the dedicated subchannels by cyclic shifts, whereby diversity gain can be maintained and interference between adjacent channels can be minimized.

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.

Abstract: A signaling method for a terminal that performs direct communication between terminals terminal is disclosed. A transmitting terminal transmits a link establishment request message for establishing a link to a receiving terminal, and the receiving terminal transmits a link establishment response message responding to this message to the transmitting terminal. The link establishment request message includes a field indicating a flow to use if the receiving terminal acquires a token.
