Abstract:
1. A method for transmitting a reverse-channel switching frame by a mobile terminal, the method comprising: preparing the reverse-channel switching frame; and transmitting the reverse-channel switching frame from the mobile terminal to a corresponding base transceiver subsystem of a source coverage area, wherein the reverse-channel switching frame comprises: information on a carrier-to-interference ratio that is included on a first slot of the reverse-channel frame, transmitted by using a first power level of the mobile terminal; information consisting of an UP or down command information in a form of first type of differential information for the carrier-to-interference ratio, transmitted by using a second power level of the mobile terminal that is lower than the first power level; and switching indication information consisting of an up or down command information in a form of second type of differential information for the carrier-to-interference ratio, the switching indication information being covered with a Walsh code corresponding to a target coverage area, the switching indication information being included on one or more time slots of the reverse-channel switching frame located after the first time slot of the reverse-channel switching frame, the up or down command information of the switching indication information being transmitted by using a third power level of the mobile terminal that is higher than the second power level.
