Patent ID: 8705433

Claim:
A base station comprising: a communication unit for performing wireless communication with a communication terminal; a channel allocation unit for allocating an individual channel in a resource of the wireless communication; a determination unit for determining a transmission/reception timing at which transmission and reception with the communication terminal through the individual channel is performed; an identification unit for identifying whether communication with the communication terminal is indirect communication with interposition of a relay device or direct communication without interposition of the relay device; and an adjustment unit for adjusting a timing at which an individual channel for upstream communication is used in accordance with a result of the identification made by the identification unit, wherein the communication unit notifies the communication terminal of the transmission/reception timing and an individual channel allocated by the channel allocation unit, the adjustment unit uses the individual channel for upstream communication at the transmission/reception timing in a case where communication with the communication terminal is direct communication, and uses the individual channel for upstream communication at a timing later than the transmission/reception timing in a case where communication with the communication terminal is indirect communication.
