Abstract

The invention provides a switching method and device for primary and secondary carriers in asymmetric uplink carrier aggregation. The method comprises that whether a base station determines whether a terminal needs carrier switching; and if yes, the base station sends indication information to the terminal so that the terminal sends data in the indicated uplink carrier according to the indication information, and the indication information is used for indicating carrier switching and comprises uplink carrier information which needs scheduling. Thus, the primary and secondary carriers are switched in asymmetric uplink carrier aggregation.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for switching primary and secondary carriers in asymmetric uplink carrier aggregation. Background technique [0002] In the current Long Term Evolution (LTE for short) system, in some industry network applications, there will be a large number of video surveillance services, that is, the demand for uplink services is greater than that for downlink services. Therefore, in order to better meet a large number of uplink According to business requirements, an asymmetric uplink carrier aggregation technology is proposed in which the number of uplink carriers is greater than the number of downlink carriers. In the asymmetric uplink carrier aggregation technology, a carrier aggregation cluster consists of a unique downlink carrier and at least two uplink carriers. [0003] In the prior art, a terminal generally only supports some uplink carriers,...
