METHOD, APPARATUS AND SYSTEM FOR OPTIMIZING INTER-CELL INTERFERENCE COORDINATION |
摘要 |
The present invention proposes a method, a radio base station and a wireless communication system for optimizing Inter-cell Interference Coordination, wherein a user equipment is communicated within a cell served by the radio base station, comprising: obtaining one or more channel conditions on the communication channel between the user equipment and the radio base station, establishing a utility function as a function of Signal to Interference-and-Noise Ratios SINRs to model the user equipment's satisfaction level in terms of quality of service and power consumption based on the obtained channel conditions, selecting a SINR that enables to maximize the value of the utility function as a target SINR, and determining a transmit power to be used by the user equipment as a function of the target SINR. Thus, a self-optimized inter-cell interference coordination (ICIC) without X2 signaling between base stations is achieved and greedy power allocation is avoid. |
