Abstract

The invention provides a communication method and a communication device. the communication method comprises steps: at least one service cell is configured to each terminal, and each service cell works on an unauthorized carrier; at least one is selected from the at least one service cell as a main cell or a main auxiliary cell for each terminal to form a main cell cluster or a main auxiliary cell cluster for each terminal; and according to the main cell cluster or the main auxiliary cell cluster, communication with each terminal is carried out. The technical scheme of the invention can improve the signal transmission probability in the main cell cluster or the main auxiliary cell cluster on the unauthorized carrier, the main cell cluster or the main auxiliary cell cluster can thus be ensured to transmit and receive necessary information and data timely and effectively, and communication time delay and efficiency requirements can be met.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular, to a communication method and a communication device. Background technique [0002] With the rapid increase of communication traffic, the 3GPP authorized spectrum is increasingly insufficient to provide higher network capacity. Therefore, 3GPP proposed the concept of LAA (LTE Assisted Access, LTE Assisted Access), which is used to use unlicensed spectrum with the help of LTE licensed spectrum. The LAA solution is based on the function of carrier aggregation to deploy the LTE system in the unlicensed frequency band. [0003] At the same time, the unlicensed spectrum can work in two ways, one is Supplemental Downlink (SDL, Supplemental Downlink), that is, only downlink transmission subframes; the other is TDD mode, which includes both downlink subframes and uplink subframes. The supplementary downlink can only be used with the help of carrier aggregation technology...
