ABSTRACT:
A code combining soft handoff method is disclosed. A mobile terminal measures a strength of respective pilot signals received from a plurality of base stations. If the strength of the received pilot signal is higher than a given value, a base station controller allocates a new code pattern to the corresponding base station to additionally receive a signal from the base station. If the strength of the received pilot signal is lower than the specified value, it drops a signal of the corresponding base station. The mobile terminal and the base station change the code pattern of one of the signals from the two base stations into a code pattern different from the code pattern of the other signal.
