Descending CoMP mixing collaboration communication method based on LTE Advanced systems

Descending CoMP mixing collaboration communication method based on LTE Advanced systems, is related to the communications field.It is strong in order to solve the edge customer inter-cell interference that existing cellular cell produced due to channeling, cell edge user throughput is low, the problem of cell edge covering is limited.LTE Advanced system descending CoMP technologies can effectively mitigate inter-cell interference, and be covered by interconnecting adjacent multiple base stations and merging multi-antenna signal with improving cell boarder.Cooperation scheme is mixed, for Cell Edge User, improves the bad communication quality of cell edge using CoMP JP；And use CoMP CB schemes to weaken inter-cell interference to other users.The present invention is applied to the descending CoMP mixing collaboration communication occasion based on LTE Advanced systems.
