Abstract: Embodiments of the present invention provide a communication method and a communications device. The method includes: generating, by a first communications device, a MAC PDU data packet, where the MAC PDU data packet includes at least one first-type MAC CE, each first-type MAC CE is used to carry information about multiple secondary serving cells, and the first communications device determines a location of the first-type MAC CE in the MAC PDU data packet according to a secondary serving cell corresponding to the first-type MAC CE; and sending, by the first communications device, the MAC PDU data packet to a second communications device, so that the second communications device obtains the first-type MAC CE, and determines, according to the location of the first-type MAC CE in the MAC PDU data packet, the secondary serving cell corresponding to the first-type MAC CE.

Abstract: The present invention includes a data processing method used for implementing data transmission between multiple carriers and a HARQ entity. A terminal receives mapping relationship information sent from a base station, where the mapping relationship information is used to indicate a mapping relationship between a HARQ entity of the terminal and a frequency resource configured by the base station for the terminal. The terminal determines frequency resource. The terminal determines a HARQ entity corresponding to the frequency resource according to the mapping relationship information, and processes a HARQ data block transmitted on the frequency resource by using the HARQ entity. Therefore, carrier communication channels for real-time transmission between the base station and the terminal are increased, to improve transmission efficiency.
