1. A communication method performed by a first communication apparatus, the method comprising:
receiving from a network device, indication information of a channel state information (CSI) reporting band, wherein the indication information indicates a subset of subbands in a bandwidth part (BWP) configured for CSI reporting;
determining based on the indication information and preset rules, CSI reporting priorities of the subset of the subbands, wherein the preset rules include numbering the subset of the subbands with corresponding index numbers arranged in an ascending numerical order and numbering a first subband in the subset of the subbands with index number 0;
determining based on the CSI reporting priorities, M subbands with higher CSI reporting priorities in the subset of the subbands compared to a remainder of subbands in the subset of subbands, wherein M is a positive integer; and
sending to the network device, CSI of the M subbands.
