GENERATING PRECODERS FOR JOINT TRANSMISSION FROM MULTIPLE TRANSMISSION POINTS TO MULTIPLE USER EQUIPMENTS IN A DOWNLINK COORDINATED MULTIPOINT TRANSMISSION/RECEPTION COMMUNICATIONS SYSTEM |
摘要 |
There is provided generating precoders for joint transmission (JT) in a downlink coordinated multi-point transmission/reception (DL COMP) wireless communications system. The system includes a plurality of transmission points (TPs) operable to communicate with a plurality of user equipments (UEs). Each UE has one of the TPs as its serving TP. The method includes transmitting channel state information (CSI) from each UE to its serving TP, wherein the transmitted CSI includes precoder matrix indicators (PMI), and using the PMI to generate precoders for transmission of data from the plurality of TPs to the plurality of UEs. |
