Abstract
A method for transmitting uplink channel state information (CSI) in a coordinated multi-point (CoMP) system is provided, which includes coding and multiplexing operations. In a multiple input multiple output (MIMO) system, a method for transmitting CSI of multiple coordinated points according to an embodiment of the present invention includes coding the CSI of the multiple coordinated points, modulating the coded CSI of the multiple coordinated points, and multiplexing the modulated CSI on a physical uplink shared channel (PUSCH). Multiplexing a rank indicator (RI) in the CSI includes multiplexing different RIs for different uplink ranks, and multiplexing a channel quality indicator/precoding matrix indicator (CQI/PMI) in the CSI includes multiplexing the CQI/PMI in a code word with the highest modulation and coding order and in other code words. Therefore, an issue with the application of the CoMP technology that one user equipment (UE) transmits CSI of multiple coordinated points may be solved, which may facilitate a further development of the CoMP technology.
