Patent ID: 8873475

Claim:
A method of controlling allocation of a radio resource for a radio resource allocation request in a base station which allocates, to a terminal, in response to the radio resource allocation request received from the terminal, a radio resource for transmitting retention data in a transmission buffer of the terminal to the base station, and which transmits to the terminal a radio resource allocation notification indicating a result of the allocation, the method comprising: receiving an amount of retention data in the transmission buffer from the terminal; cyclically allocating the terminal a radio resource for the radio resource allocation request when the amount of retention data is zero; and determining a transmission cycle that is suited to the amount of retention data as a transmission cycle of the notification of radio resource allocation for transmitting the retention data in the transmission buffer when the amount of retention data is not zero, and stopping the allocation of the radio resource for the radio resource allocation request and receiving a CQI(Channel Quality Indicator) from the terminal in a transmission cycle in which the radio resource for the radio resource allocation request was allocated during cyclic transmission of the radio resource allocation notification.
