Abstract
The present invention discloses a method and device of reporting channel state information, including: user terminal selects the codebook used in reporting precoding matrix indicator (PMI) from double-stage codebook and selects PMI from the codebook; double-stage codebook involves codebook reflecting long-term/broadband information and that reflecting short-term/frequency selective channel information; and user terminal calculates channel quality indication; therein, when reporting through physical uplink control channel (PUCCH), the parameter used in calculating channel quality indication (CQI) includes the precoding matrix indicator (PMI) reported by user terminal through physical uplink shared channel (PUSCH); when reporting through physical uplink shared channel (PUSCH), the parameter used in calculating CQI includes the precoding matrix indicator (PMI) reported by user terminal through physical uplink control channel (PUCCH); user terminal selects the PMI and calculates CQI according to the specified reporting mode and reporting RI. The present invention can realize double-stage feedback by using the present feedback channel.
