Title
Multiuser CoMP transmit processing with statistical channel state information at the transmitter
Abstract
Coordinated Multi-Point (CoMP) transmission/reception is a candidate technique for increasing cell-average and cell-edge throughputs in next-generation wireless systems. Joint Processing (JP) can enhance CoMP systems' performance, mainly employing precoding algorithms based on channel state information at the transmitter (CSIT). Currently, many research efforts focus on reducing feedback and optimizing precoding with partial CSIT. This paper proposes a model to approximate the downlink multiuser CoMP channel based on the channel statistics and taking into account the channel temporal variation. The proposed model is relatively simple, highly reduces feedback overheads, and might be employed to perform precoding. Compared to using linear precoding with instantaneous CSIT, results show that throughput losses are negligible for low SNR values and moderate for high SNR values when using the proposed model. Analyses considering users all over the cell and in the cell-edge are also presented.
