Coordinated Multi Point (CoMP) has been standardized as an important factor of LTE-Advanced in 3rd Generation Partnership Project (3GPP) in order to improve cell-edge throughput performance. Coordinated Beamforming CoMP (CB CoMP), where a strongly interfering cell coordinates its transmit precoder so as to minimize the interference to CoMP User Equipment (CoMP UE), has been studied as a candidate of CoMP scheme, and Best Companion Precoding Matrix Indicator (BCI) was proposed as a Channel State Information (CSI) feedback from CoMP UE for CB CoMP. However, system performance might be deteriorated if the feedbacked BCI is not effectively used at the interfering cell. In this paper, we propose multiple BCI feedback in order to improve system performance by increasing degree of freedom of scheduling at the interfering cell. We also carry out the theoretical analysis and the system level simulation to evaluate the throughput performance with the proposed feedback and the simulation results confirm the effectiveness of the proposal. |
