摘要:
Provided is a allocation controlling method 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. When an amount of retention data in the transmission buffer received from the terminal is not zero, a transmission cycle that is suited to the retention amount is determined as a transmission cycle of the notification of radio resource allocation for transmitting the retention data in the transmission buffer and, during cyclic transmission of the radio resource allocation notification, the allocation of a radio resource for the radio resource allocation request is stopped.
