Abstract: A method and apparatus for applications of identification of variations of propagation path to transmit diversity control. Transmit diversity parameters may be modified according to detected dynamics, which may, for example, be related to changes in actual propagation and network conditions. Such dynamics may be referred to as mobility parameters. Mobility parameters may apply to variability in a propagation path due to any conditions. Determination of a mobility parameter may be conducted using one or more of multiple parameters available to the mobile terminal. Such feedback information indication, which is related to the propagation path conditions, may be provided to the apparatus, which would attempt to find a more desired mode of operation, which may lead to reduction in power and the improvement of the quality of transmission.

Abstract: A method and system for improving closed loop feedback in transmit diversity communication. In one embodiment of the invention, a predetermined variation of one or more transmit diversity parameters is performed at the transmit diversity transmitter. The receiver compares the transmit diversity parameter values of the received signals to the predetermined variation and transmits to the transmitter a value of a transmit diversity correction parameter. The transmitter may use this correction value to modify the transmit diversity parameter in a subsequent transmission.
