摘要: A radio communication system channel state information (CSI) feedback method and device are provided, wherein the includes: determining parameters needed for CSI in first system, enabling structure on physical uplink control (PUCCH) of to depend PUCCH second system; informing these user equipment; transmitting reference symbol (CSI-RS) periodically equipment so that computes be fed back; receiving back by corresponding CSI-RS, according each bandwidth part (BP) is obtained jointly encoding best subband quality indicator (CQI) within a BP precoding matrix (PMI) same BP.
