Patent ID: 7738420

Claim:
A method for allocating a subchannel and power to a plurality of user equipments (UEs) in a communication system that divides a channel into a plurality of subchannels and includes a plurality of UEs, the method comprising: collecting, by a state information collector, subchannel state information for the respective UEs; calculating, by a parameter calculator, a plurality of subchannel state prediction parameter values for the respective UEs using the subchannel state information; allocating, by a subchannel and power allocator, at least one subchannel among the plurality of subchannels to a first UE having a highest priority among the plurality of UEs; determining, by the subchannel and power allocator, whether to allocate additional power to the at least one subchannel based on the plurality of subchannel state prediction parameter values; and allocating, by the subchannel and power allocator, additional power to a subchannel that needs the additional power among the at least one subchannel, wherein allocating the additional power comprises: comparing a subchannel state prediction parameter value of the at least one subchannel with a threshold value; and allocating additional power to a subchannel having a subchannel state prediction parameter value less than the threshold value.
