Errors in closed loop transmit diversity (CLTD) feedback signaling may be
detected and/or corrected by a mobile station, according to aspects of
the present invention, based on signals received from a base station. The
mobile station is generally configured to compute antenna weights to be
applied at the base station and feed back corresponding antenna control
bits to the base station, as in conventional CLTD systems. However,
rather than automatically process subsequent transmissions received from
the base station as if the base station properly received the antenna
control bits and applied the computed antenna weights, the mobile station
attempts to determine the antenna weights actually applied at the base
station, and uses these determined antenna weights for processing the
subsequent transmissions. Accordingly, even if a feedback signaling error
occurred, resulting in the base station using the wrong antenna weights,
the mobile station may properly process the transmissions. According to
some aspects of the present invention, the base station transmits (feeds
forward) antenna control bits actually received from the mobile station
on a feed forward channel, and the mobile station processes subsequent
transmissions using antenna weights generated based on the fed forward
antenna control bits.
