Abstract
A communication method and apparatus, relating to the field of wireless communications, the method comprising: a terminal device sending capability information to an access network device, the capability information comprising a maximum carrier number N supported by the terminal device and used for receiving downlink data in parallel, N being an integer greater than 1. And then, the access network equipment sends a configuration message to the terminal equipment, the configuration message comprises the configuration information of the primary cell and the respective configuration information of the M secondary cells, and M is an integer greater than N-1, namely, the number of cells configured for the terminal equipment by the access network equipment is greater than the maximum carrier number N supported by the terminal equipment. Therefore, the access network equipment can select different auxiliary cells from the M auxiliary cells and instruct the terminal equipment to activate the selected auxiliary cells, so that the terminal equipment can receive the downlink data in parallel on the activated auxiliary cells and the main cell, and the requirement of the terminal equipment for receiving the downlink data in parallel at different time periods can be met.
