Abstract
A power control system method for controlling the downlink (DL) transmit power from a base station (BS) to a mobile station (MS) in a cellular telecommunications network. A power balancing value &Dgr;P is divided into a number of smaller correction implements which are distributed over a plurality of spaced apart slots for DL power control. For example, if it is desired to correct DL transmit power by six dB, a total of six different correction values of one dB each may be implemented with adjacent ones of the correction values being spaced apart by a number of slots. The distribution or spreading of DL transmit power corrections over a period of time results in a plurality of smaller corrections as opposed to one or a few large corrections, thereby reducing potential adverse effects on the inner loop power control of the network.
