    摘要： An apparatus and method for allocating a channel and power by a Base Station (BS) in a communication system are provided. The method includes, 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, selecting a UE to be allocated each subchannel in each subframe based on results of the performed scheduling, 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 performed scheduling; and allocating power to all UEs including the selected UE and the non-selected UE by preset subframe periods by using the computed power metric.

    摘要： A method and an apparatus maximize the capacity of a wireless communication network by taking into consideration inter-cell interference coordination. A home cell's capacity sensitivity to interference is calculated. At least one neighbor cell's capacity sensitivity to interference is collected. And at least one UE located in the home cell is scheduled based on the home cell's capacity sensitivity and the neighbor cell's capacity sensitivity. Accordingly, it is possible to achieve power and allocation control to maximize the capacity of the overall network including neighbor cells increase the system capacity in a cellular system in which inter-cell interference is large, and adaptively perform a UE scheduling in real time to changing distribution of UEs because information on a change in the capacity of each cell is shared by periods.

    摘要： A method and an apparatus for pre-scheduling in a closed-loop multiple user multiple input multiple output (MU-MIMO) antenna system. A base station receives channel information representing a downlink channel condition of each mobile station from mobile stations in a cell, and determines a candidate user group for each of frequency bands included in an entire frequency band, based on the channel information, the candidate user group including mobile stations to which resources can be simultaneously allocated. The base station also instructs a mobile station included in each candidate user group to transmit a sounding signal through a corresponding frequency band. If the sounding signal is received through the corresponding frequency band, the base station performs a scheduling with regard to the mobile station included in each candidate user group.

    摘要： A partial iterative detection and decoding apparatus in a Multiple Input Multiple Output (MIMO) system includes a detector for detecting signals received through at least one receive antenna to generate a first soft decision value, a decoder for decoding the first soft decision value to generate a second soft decision value, and a reliability determiner for determining a signal to be iteratively detected and decoded by using the second soft decision value. Accordingly, the complexity of the receiver is reduced and the number of iterations limited due to the complexity is increased, thereby improving the performance of the receiver.
