Abstract: Provided is a control method of a control apparatus for a multi-cell communication system including a plurality of cells, the method including determining a cell edge terminal or an inner cell terminal from each of terminals included in each of the cells, and selecting, from base stations included in the plurality of cells, a first base station and a second base station. The first base station may serve all of a corresponding cell edge terminal and a corresponding inner cell terminal, and the second base station may serve only the corresponding inner cell terminal between the corresponding cell edge terminal and the corresponding inner cell terminal.

Abstract: A system and method for non-uniform bit allocation in the quantization of channel state vectors is provided. A method for communications node operation includes receiving a bit-allocation profile for use in quantizing channel state information, measuring a communications channel between the communications node and a controller, generating channel state information based on the measurement, computing a bit representation of the channel state information, transmitting the bit representation to the controller, and receiving a transmission from the controller. The computing makes use of quasi-tail-biting trellis decoding, and the computing is based on the bit-allocation policy. The transmission makes use of the channel state information transmitted by the communications node.

Abstract: A method for allocating resources in an orthogonal frequency division multiple access (OFDMA) network, where each cell in the network has a center region and an edge region. The cell center region uses a frequency band orthogonal to the frequency band used by the cell edge region. The frequency band is made up of resource blocks (RBs) or non-overlapping sets of subcarriers. Upon availability of cell-center RBs, cell-center user equipment (UEs) are assigned resource blocks. A fixed number of cell edge regions from a few adjacent cells form a cluster, and only the cell edge regions with the highest achievable throughput rate within each cluster gets to transmit in a given scheduling instance.
