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 continues to monitor the PDCCH, measure, and report the problem of consuming its own battery energy, and no effective solution has been proposed so far.

Embodiment 1

[0076] Please also refer to Figure 4 , Figure 5 , Figure 4 is a schematic diagram of base station deleting component carrier 3 according to the preferred embodiment 1 of the present invention, as shown in Figure 4As shown, the base station (eNB1) has three component carriers, namely component carrier 1, component carrier 2 and component carrier 3, and the coverage of the three component carriers overlaps. In this embodiment, eNB1 needs to delete component carrier 3, which is triggered by the arrival of the primary user (for example: radio and television); Used by users (for example: no broadcast TV data is sent on this frequency), but used by eNB1 as component carrier 3; when the main user arrives, that is, broadcast TV data needs to be sent on frequency f1, eNB1 needs to "give up" its other The borrowed frequency f1; therefore, eNB1 needs to delete the component carrier 3 so that the primary user can send data on f1, otherwise it will cause interference to the primary ...

Embodiment 2

[0088] Please also refer to Image 6 , Figure 7 , Image 6 is a schematic diagram of the base station deleting the component carrier 3 according to the second preferred embodiment of the present invention, as shown in Image 6 As shown, the base station (eNB2) has three component carriers, namely component carrier 1, component carrier 2 and component carrier 3, and the coverage of the three component carriers overlaps. In this embodiment, eNB2 needs to delete component carrier 3, which is triggered by the arrival of the primary user (for example: radio and television); Used by users (for example: no broadcast TV data is sent on this frequency), but used by eNB2 as component carrier 3; when the main user arrives, that is, broadcast TV data needs to be sent on frequency f1, eNB2 needs to "give up" its The borrowed frequency f1; therefore, eNB1 needs to delete the component carrier 3 so that the primary user can send data on f1, otherwise it will cause interference to the pri...

Embodiment 3

[0127] Please also refer to Figure 10 , Figure 11 , Figure 10 is a schematic diagram of the base station deleting the component carrier 3 according to the third preferred embodiment of the present invention, as shown in Figure 10 As shown, the base station (eNB3) has three component carriers, namely component carrier 1, component carrier 2 and component carrier 3, and the coverage of the three component carriers overlaps. In this embodiment, eNB3 needs to delete component carrier 3, which is triggered by the arrival of the primary user (for example: radio and television); Used by users (for example: no broadcast TV data is sent on this frequency), but used by eNB3 as component carrier 3; when the main user arrives, that is, broadcast TV data needs to be sent on frequency f1, eNB3 needs to "give up" its other The borrowed frequency f1; therefore, eNB1 needs to delete the component carrier 3 so that the primary user can send data on f1, otherwise it will cause interferenc...

Abstract

A method and apparatus of component carrier deletion are disclosed. The method comprises that: a base station deletes a component carrier; in the case of receiving a measurement report obtained after measuring the deleted component carrier and sent by an equipment user (UE), the base station sends media access control control element (MAC CE) control information to the UE over a predetermined component carrier, to inform the UE to perform de-active operation for the deleted component carrier, or stops data scheduling for the UE on the deleted component carrier, to make a terminal to perform de-active operation for the deleted component carrier actively after a predetermined time interval. An effect of avoiding the UE to repeat monitoring, measuring, and reporting operations after the base station deleting the component carrier can be achieved through the present invention.

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 ...
