Abstract

A method of setting the transmit power of a mobile station operating in a radio communication system is provided. Communications are effected to a plurality of mobile stations via at least one base station. The method includes the steps of operating the mobile station in a first power control mode and receiving a message at the mobile station, transmitted by the at least one base station, the message informing the mobile station to reduce the transmit power of the mobile station below a lower threshold level of a power control range in the first power control mode. The mobile station then operates in a second power control mode, in response to the message. In utilising this method, the mobile station can still continue its transmissions, even though its transmission power may be outside of the minimum power threshold level of a power control range.
