Coordinated multi-point transmission and reception (CoMP) for single user,named as SU-CoMP,is considered as an efficient approach to mitigate inter-cell interference in orthogonal frequency division multiple access (OFDMA) systems.Two prevalent approaches in SU-CoMP are coordinated scheduling (CS) and joint processing (JP).Although JP in SU-CoMP has been proved to achieve a great link performance improvement for the cell-edge user,efficient resource allocation (RA) on the system level is quite needed.However,so far limited work has been done considering JP,and most existing schemes achieved the improvement of cell-edge performance at cost of the cell-average performance degradation compared to the single cell RA.In this paper,a two-phase strategy is proposed for SU-CoMP networks.CS and JP are combined to improve both cell-edge and cell-average performance.Compared to the single cell RA,simulation results demonstrate that,the proposed strategy leads to both higher cell-average and cell-edge throughput.
