Abstract

The invention provides a communication method, a communication apparatus and a terminal. The communication method comprises the following steps: determining a main cell group or an auxiliary cell group that works on unauthorized carriers by the terminal; and performing wireless link monitoring on the main cell group or the auxiliary cell group, wherein the main cell group or the auxiliary cell group is composed of and selected from at least one service cells that work on the unauthorized carriers, and each service cell works on one unauthorized carrier. The technical scheme of the invention can deploy the main cell group or the auxiliary cell group on an unauthorized frequency band so as to perform the wireless link monitoring on the main cell group or the auxiliary cell group and reduce the counts of RLF, so that the problems of large signaling overhead and loss throughput caused by the re-configuration of RRC-Reestabilishment or the main and auxiliary cell groups resulting from that the RLF is frequently detected on the unauthorized frequency band can be solved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular, to a communication method, a communication device and a terminal. 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 aggregatio...
