METHOD AND APPARATUS FOR MODE TRANSITION OF TRANSMIT DIVERSITY IN MOBILE COMMUNICATION SYSTEM USING TRANSMIT DIVERSITY

摘要

The present invention in a mobile communication system of the mobile terminal for transmitting a transmit diversity information to the base station at least a base station and the plurality of antenna consisting of one or more antennas to implement the maximum Transmit Diversity, the transmission diversity mode of in the case to change method of weighting the data for transmitting via the antenna to implement a base station data to be transmitted are up to transmit diversity, transmit diversity mode, the process of storing in association with each other, the weights used by the respective and, that the received step of determining whether or not to use the transmit diversity information mode is changed and the mode when it is determined that change transmitted through the antenna weights that are stored in correspondence with the weight previously used to change the mode It consists of a process to be applied to the data.; Transmit diversity, mode 1, mode 2, the weight, the feedback signal (FSM)
