1. A communication method, comprising:
obtaining first capability information, wherein the first capability information indicates a quantity of multiple-input multiple-output (MIMO) layers supported on a first carrier and a quantity of MIMO layers supported on a second carrier when uplink transmission is performed on the first carrier and the second carrier in time division multiplexing mode;
obtaining inter-carrier switching period information, wherein the inter-carrier switching period information indicates a carrier switching period between the first carrier and the second carrier;
sending the first capability information and the inter-carrier switching period information to a network device; and
receiving indication information from the network device, wherein the indication information indicates performing uplink transmission on the first carrier and the second carrier in the time division multiplexing mode.
