Abstract:
An apparatus generating an autonomous Pilot Strength Measurement Message (PSMM) by a mobile station in a multi-carrier wireless communication system, comprising:means for receiving a plurality of pilots at a mobile station, wherein the plurality of pilots are transmitted from at least one base station; means for using a first pilot strength definition defined by the relationship: PS2=10Ã—log{[(Pilot Ec/Io)1/&Dgr;1+(Pilot Ec/Io)2/&Dgr;2+(Pilot Ec/Io)i/&Dgr;i]i}, where (Pilot Ec/Io)i is the pilot Ec/Io measured on the i-th carrier frequency, &Dgr;i is the ratio between the transmit power of pilot i and the transmit power of the primary pilot;means for checking a set of rules, wherein the set of rules is for generating the PSMM by manipulating the first pilot strength definition; and means for generating the PSMM for transmission from the mobile station.
