Abstract:
1. A method for managing uplink channel resources in a mobile communication terminal located in a first cell, comprising: measuring, at the mobile communication terminal, channel responses of a downlink channel signal for each downlink frequency band of a plurality of frequency bands, the downlink channel signal transmitted from a base station of a second cell; dividing the plurality of frequency bands into a first frequency band and a second frequency band; and determining, by the mobile communication terminal, a transmission signal power of an uplink channel signal for each uplink frequency band of the plurality of frequency bands based on the channel responses, wherein the first frequency band corresponds to a first downlink frequency band for receiving the downlink channel signal and corresponds to a first uplink frequency band for transmitting the uplink channel signal, the second frequency band corresponds to a second downlink frequency band for receiving the downlink channel signal and corresponds to a second uplink frequency band for transmitting the uplink channel signal, and the transmission signal power for the first uplink frequency band is selected to be lower than the transmission signal power for the second uplink frequency band, based on determining, by the mobile communication terminal, that the channel response of the downlink channel signal for the first downlink frequency band is better than the channel response of the downlink channel signal for the second downlink frequency band.
