Abstract
In a wireless communication system, in which a mobile station is operable to monitor the signal strengths of a plurality of pilot signals transmitted from a plurality of base stations, a method and device by which the mobile station determines the membership of Active Set pilots by generating a quality metric derived as a function of (i) detected pilot signal strengths corresponding to the Active Set of pilots, and (ii) detected pilot signal strengths corresponding to a non-Active Set of pilots, determining a threshold value, the threshold value determined as a function of the quality metric, and assigning the pilot to, or removing the pilot from, the Active Set of pilots if the signal strength corresponding to the pilot exceeds the threshold value.
