Abstract
In a disclosed mobile communications system wherein packet communication between a base station and its subordinated mobile station is established based on a reservation packet, the packet communication uses controlled transmission power and a radio resource allocated based on reception quality information received from the mobile station. The base station comprises a memory for storing its own cell reception power transmitted from the mobile station based on radio resource allocation status for the mobile station; a neighboring interference calculating unit for calculating neighboring cell interference based on the its own cell reception power and the reception quality information; an interference margin determining unit for establishing neighboring cell interference margin for preparing for neighboring cell interference; and a transmission power determining unit for determining transmission power for each packet transmitted from the mobile station based on the reception quality information and the interference margin.
