Abstract: This application provides a method for reporting a terminal device capability and a communications apparatus. The method includes: The terminal device generates first indication information and sends the first indication information to a network device. The first indication information is used to indicate one or more frequency domain parameters and one or more of the following capability parameters associated with each frequency domain parameter: a port quantity, a spatial domain parameter, a reference signal resource quantity, and a total port quantity. The frequency domain parameter is used to indicate a maximum quantity of frequency domain units that can be supported by the terminal device. The frequency domain unit is a frequency domain unit based on which the terminal device feeds back a PMI. Each capability parameter group may be used to indicate one combination of a plurality of parameters that can be supported by the terminal device.

Abstract: This application relates to channel state information (CSI) feedback methods and devices. One method comprises: receiving, by a terminal device from a network device, indication information of a channel state information (CSI) reporting band; determining, by the terminal device, based on the indication information, a subset of subbands in a bandwidth part configured for the terminal device for CSI reporting; determining, by the terminal device, CSI reporting priorities of the subset of the subbands based on index numbers of the subset of the subbands, wherein the index numbers of the subset of the subbands are numbered in an ascending numerical order; and sending, by the terminal device to the network device, CSI of M subbands with higher CSI reporting priorities in the subset of the subbands compared to a remainder of subbands in the subset of subbands.
