    摘要： Various devices and methods are disclosed to support clustering optimization in a communication system. For example, multiple nodes of the communication system can be segmented into multiple clustering plans. Each clustering plan can include multiple clusters that do not overlap with one another within that clustering plan. At least one of the clusters of one clustering plan can overlap at least one of the clusters of at least one other clustering plan. Each node could be a non-boundary node in at least one cluster of at least one clustering plan. Multiple nodes of the communication system can alternatively be segmented into clusters having expanding and contracting borders.

    摘要： A system is provided for optimizing throughput in a communication system. During operation, the system receives, at a first antenna, estimated channel state information (CSI) at least one channel between the first antenna and at least one second antenna. The system obtains antenna correlation information associated with the first antenna and the second antenna, respectively. The system further calculates a set of noise terms associated with random noise for the at least one channel, and optimizes a configuration of beamformers for the first antenna and the at least one second antenna that maximizes a throughput of all antennas, in accordance with the estimated CSI, the obtained antenna correlation information, and the noise terms.
