1. A method for use in a cellular radio communication system that includes a first cell and a second cell, where a mobile radio is currently served by a first base station in the first cell, comprising:
(a) the mobile radio generating a relative path gain related quantity for an uplink signal transmission from the mobile radio, where the relative path gain related quantity is based on a comparison of a first path gain related quantity for an uplink signal transmission from the mobile radio to the second base station with a second path gain related quantity for the uplink signal transmission from the mobile to the first base station, and
(b) controlling uplink resources from the mobile radio in the first cell based on the relative path gain related quantity.
