Patent ID: 8027374

Claim:
A method of modifying a transmit diversity signal comprising: transmitting during a first transmission period a transmit diversity signal using a first transmit diversity parameter value, wherein said first transmission period comprises at least a full slot period; transmitting during a second transmission period immediately subsequent to said first transmission period, a transmit diversity signal using a second transmit diversity parameter value; during a first data collection period, receiving from a receiver a first plurality of quality indication signals pertaining to system performance using said first transmit diversity parameter value, wherein said first data collection period begins after the start of the first transmission period; during a second data collection period, receiving from a receiver a second plurality of quality indication signals pertaining to system performance using said second transmit diversity parameter value, wherein said second data collection period begins after the start of the second transmission period; and calculating a subsequent transmit diversity parameter value based on said first plurality of quality indication signals.
