A method and apparatus for tracking signals in a wireless communication
system. In one embodiment, a base station includes a rake antenna having
multiple fingers. When any of the fingers goes out of lock, the base
station waits a predetermined time period and then adjusts the lock
detect filter. The adjustment is based on comparison of received signal
energy to an adjusted energy threshold. The comparison may result in an
increased energy level of the filter. In one embodiment, if a mobile
station is in soft hand-off, the base station ignores the lock state of
the fingers and transmits power control information based on the received
signal energy. If the mobile station is not in soft hand-off a
predetermined power control pattern is applied for gradual power
adjustment.
