DATA TRANSMISSION METHOD AND APPARATUS IN WIRELESS COMMUNICATION SYSTEM USING PLURAL FREQUENCIES IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a data transmission method and apparatus for a wireless communication system using a plurality of frequencies in the wireless communication system. According to one aspect of the present invention, a data transmission method by a UE using a plurality of uplink frequencies in a wireless communication system involves receiving, by the UE, grants each of the plurality of uplink frequencies from Node B, dividing the maximum power of the UE among each of the plurality of uplink frequencies according to the grants received for each of the plurality of uplink frequencies, selecting a size of a transmission block for each of the plurality of uplink frequencies by taking the divided powers and the received grants into consideration, and stopping data transmission through a first uplink frequency among the plurality of uplink frequencies when the size of a transmission block selected for the first uplink frequency is smaller than the size of a minimum transmission block which the UE must transmit through the first uplink frequency.
