Abstract
A control method and device for uplink access transmission power are provided that can control inter-cell interference in a radio communications system. In a radio communications system including a plurality of radio communication devices which control a plurality of cells respectively, each radio communication device detects an uplink access delay in its own cell, compares the uplink access delay with a target delay, and, based on the result of this comparison, controls a value related to uplink access transmission power.
