- Abstract
The uplink coordination in LTE system is mainly based on soft combining, and is suitable for cells connected with ideal transport condition, but it is difficult to deploy. According to the principle of multi-cell joint detection in TD-SCDMA system, the technique of cloud interference rejection combining (Cloud IRC) is proposed, and it can be used between cells without ideal transport condition. According to test in commercial LTE network, the throughput of cell-edge users can be improved by 89. 9% on average with the technique of soft combining, and 29. 3% with the technique of Cloud IRC. With both of them, the quality of experience is improved in the whole network.
