Abstract
A switching frame includes information on a carrier-to-interference ratio that is included on a first time slot corresponding to a boundary with a previous frame and corresponds to a target coverage area having a first power level, and at least on up/down command information for the carrier-to-interference ratio that is included after the first time slot and has the same power level as the first power level.
Claims11
A method of changing a source coverage area to a target coverage area of a terminal, comprising:
- searching the target coverage area among active coverage area sets during transmission of a carrier-to-interference ratio of the source coverage area;
- including information on a carrier-to-interference ratio of the target coverage area and at least one up/down command information for the carrier-to-interference ratio of the target coverage area in a switching frame with substantially the same power level when switching from the source coverage area to the target coverage area;
- and
- transmitting the switching frame to a corresponding base transceiver subsystem of the source coverage area.
1 more element
A reverse-channel switching frame comprising:
- information on a carrier-to-interference ratio that is included on a first slot of a frame and corresponds to a target coverage area having a first power level;
- and
- at least one up/down command information for the carrier-to-interference ratio that is included after the first time slot and has substantially the same power level as the first power level.
A reverse-channel quality indicator channel comprising:
- at least one first frame having information on a carrier-to-interference ratio of a target coverage area having a first power level, at least one up/down command information for the carrier-to-interference ratio having the first power level, and at least one up/down command information having a second power that is lower than the first power level;
- and
- at least one second frame having information on a carrier-to-interference ratio of a target coverage area having the first power level, and at least one up/down command information having the second power level.
