Problems solved by technology

However, it is obvious that the base station has deleted the corresponding component carrier, and the UE's monitoring, measurement, and reporting of the PDCCH is a meaningless behavior. Such operations by the UE will only consume its own battery energy, but have no practical application value. of
However, the prior art does not provide a corresponding solution for this meaningless operation of the UE.
[0008] In the related art, when the base station has deleted the corresponding component carrier, the UE still repeatedly monitors the PDCCH, measures, and reports the operation of consuming its own battery energy, and no effective solution has been proposed yet.

Abstract

The invention discloses a method and device of deleting a component carrier wave, wherein the method comprises the following steps: a base station sends control information to user equipment UE through preset component carrier wave; the control information is used for indicating the UE to carry out deactivation operation or release operation to a to-be-deleted component carrier wave; when the UE completes the deactivation operation or release operation to the to-be-deleted component carrier wave, the base station deletes the to-be-deleted component carrier wave. By employing the invention, the repeat monitoring, measuring and reporting operations of the UE after the base station deletes the component carrier wave can be prevented.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for deleting component carriers. Background technique [0002] The Long Term Evolution-Advanced (LTE-A for short) system has a peak rate of 1 Gbit / s under low mobility and a peak rate of 100 Mbit / s under high mobility. So in order to support such a peak rate, we need a larger bandwidth, and the spectrum with such a large bandwidth is difficult to find. Therefore, the LTE-A system needs to expand the bandwidth that can be used by the user equipment (User Equipment, referred to as UE), and thus introduces carrier aggregation (CarrierAggregation, referred to as CA) technology, that is, the same enhanced Node Base Station (referred to as UE) Multiple continuous or discontinuous carriers under the eNB) are aggregated together and serve the UE at the same time to provide the required rate. [0003] In the LTE-A system, after the UE enters the connected state, it...
