Application of BBU+RRU Based Comp System to LTE-Advanced
LTE-Advanced system which based on orthogonal frequency division multiplexing (OFDM) can eliminate intra-cell interference but still can not mitigate inter-cell interference (ICI). Coordinated Multi-Point transmission/reception (CoMP) is one of the candidate techniques for LTE-Advanced systems to increase the cell average and cell edge user throughput in the both uplink and downlink. Although CoMP naturally increases system complexity, it has potentially significant capacity and coverage benefits, making it worth a more detailed consideration. In this paper, we present our initial views on the application of BBU+RRU based CoMP system to LTE-Advanced. Furthermore, simulation results for uplink show that the CoMP joint processing can bring significant gains to both the average sector throughput and the 5% of user throughput.
