FIELD: radio engineering and communications.
SUBSTANCE: method of transmitting channel state information (CSI) in coordinated multi-point (CoMP) system includes coding and multiplexing actions. In system with multiple inputs and multiple outputs (MIMO) transmission method CSI of multiple coordinated points includes encoded CSI of multiple coordinated points, modulating encoded CSI of multiple coordinated points and multiplexing modulated CSI in physical uplink shared channel (PUSCH). Multiplexing rank indicator (RI) in CSI includes multiplexing of different RI for different ranks of uplink, and multiplexing of channel quality indicator/pre-coding matrix indicator (CQI/PMI) in CSI includes multiplexing CQI/PMI in code word with highest order of modulation and coding and in other code words.
EFFECT: high communication reliability due to development of technology CoMP.
