摘要:
An uplink radio resource allocation method allocates, at a radio base station, an uplink radio resource used for uplink user data transmission to a mobile station. The method includes: allocating, at the radio base station, the uplink radio resource, so that total received power in an particular cell of the radio base station is equal to a first target value assigned by a radio network controller; and allocating, at the radio station, the uplink radio resource, so that a ratio of first received power from a serving mobile station to second received power from a non-serving mobile station is equal to a second target value assigned by the radio network controller, a serving cell of the serving mobile station being the particular cell, a non-serving cell of the non-serving mobile station being the particular cell.
