Apparatus and method for allocating channel and power in communication system

A Base Station (BS) in a communication system, the BS comprising:

• a channel allocator for performing one of a first scheduling, which uses inter-cell cooperation information received from at least one neighboring BS and a data rate received from each User Equipment (UE), and a second scheduling, which uses both an average data rate for each subchannel computed by accumulating the data rates for a preset time period and the inter-cell cooperation information, and for selecting a UE to be allocated each subchannel in each subframe based on results of the performed scheduling;
• and
• a power allocator for computing a power metric for each of the selected UE and a non-selected UE by using the inter-cell cooperation information, the average data rate, an amount of performance change of the selected UE, and the results of the first scheduling, and for allocating power to all UEs including the selected UE and the non-selected UE by preset subframe periods by using the computed power metric.

A Base Station (BS) in a communication system, the BS comprising:

• a channel allocator for performing scheduling by using inter-cell cooperation information received from at least one neighboring BS and channel state information received from each User Equipment (UE), and for selecting a UE combination including at least one UE to be allocated each subchannel in each subframe based on results of the scheduling;
• and
• a power allocator for computing a power metric for each of a selected UE and a non-selected UE by using data rate information of the at least one UE estimated based on the channel state information, the inter-cell cooperation information, an amount of performance change of the at least one UE, and the results of the scheduling, and for allocating power to all UEs by preset subframe periods by using the computed power metric.
