Abstract

Embodiments of the present disclosure provide a solution relating to CSI. According to embodiments of the present disclosure, a terminal device receives from a network device at least one setting of a channel state information (CSI) report, the at least one setting indicates a plurality of channel state information reference signal (CSI-RS) resources, the terminal device determines, based on the at least one setting, at least one first amplitude coefficient, at least one second amplitude coefficient, at least one phase coefficient, and at least one bitmap for non-zero coefficient indication, and a first index corresponding to the strongest coefficient, the terminal device determines, based on a first priority, the priority of at least one codebook indicator corresponding to the first index, and based on a second priority, the priority of at least one codebook indicator corresponding to the second index, the first index differs from the second index, and the terminal device transmits at least one codebook indicator to the network device in the CSI report.
