Method For Reporting Terminal Device Capability And Communications Apparatus

A communications apparatus, comprising:

• at least one processor, and one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
• generating first indication information, wherein the first indication information indicates one or more frequency domain parameters and at least one of the following capability parameters associated with each of the one or more of frequency domain parameters:
• a port quantity, a reference signal resource quantity, or a total port quantity;
• each of the one or more frequency domain parameters and one or more capability parameters associated with the respective frequency domain parameter indicate one combination of a plurality of parameters simultaneously supported by a terminal device;
• each of the one or more of the frequency domain parameters indicates a maximum quantity of first frequency domain units that is supported by the terminal device;
• each of the first frequency domain units is a frequency domain unit based on which the terminal device reports a precoding matrix indicator (PMI);
• the port quantity is a maximum quantity of ports in one reference signal resource;
• the reference signal resource quantity is a maximum quantity of reference signal resources;
• and the total port quantity indicates a total quantity of ports in all reference signal resources;
• and
• sending the first indication information to a network device.
