ABSTRACT:
A mobile station (MS) and method for estimating received signal strength of a radio signal from a neighboring cell in a cellular radio telecommunication network. The MS measures the received signal strength of the radio signal over a plurality of frames, and calculates an average received signal strength. During an idle frame, the MS receives a synchronization channel (SCH) signal, and determines a channel estimate for the SCH using a known extended training sequence. The extended training sequence is then modified with the channel estimate, and the modified extended training sequence is subtracted from the received SCH signal to obtain a residual signal. The MS calculates a residual energy of the residual signal, and subtracts the residual energy from the average received signal strength of the radio signal to obtain an estimated received signal strength of the radio signal from the neighboring cell.
