1. A communication method, comprising:
receiving first indication information, wherein the first indication information indicates M power offset values of a reference signal resource, M is an integer greater than or equal to 2, and each power offset value is an assumption of a ratio of energy per resource element (EPRE) on a physical downlink shared channel (PDSCH) to an EPRE of a channel state information reference signal (CSI-RS);
determining, based on the M power offset values, M pieces of channel state information (CSI) corresponding to the reference signal resource, wherein each power offset value has a one-to-one correspondence with a piece of CSI of the M pieces of CSI; and
sending N pieces of CSI in the M pieces of CSI, wherein N is a positive integer less than M, transmission efficiency of any of the N pieces of CSI is higher than transmission efficiency of any of (M-N) pieces of CSI, and the (M-N) pieces of CSI are CSI other than the N pieces of CSI in the M pieces of CSI; and
wherein the transmission efficiency of each piece of CSI is determined based on at least one of a rank indicator (RI) or a channel quality indicator (CQI) of the respective piece of CSI.
