A method and terminal for feeding back channel state information are applicable to a 4-antenna system. The method comprises: a terminal acquiring channel state information, the terminal performing joint encoding on PMI1 information and RI information into a 4-bit or 5-bit feedback report, or, performing joint encoding on PMI1 information and PMI2 information into a 4-bit feedback report, or, performing encoding on PMI2 information into a 2-bit feedback report; and the terminal feeding back the feedback report on a physical uplink control channel. |
