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
The present invention relates to the communications field, in particular to a kind of method and device of deleting component carrier.
Background technology
Senior Long Term Evolution (Long Term Evolution-Advanced, referred to as LTE-A) system peak rate under Hypomobility reaches 1Gbit/s, and under high mobility, peak rate reaches 100Mbit/s.In order to support such peak rate, we need larger bandwidth so, and the frequency spectrum of so large bandwidth is difficult to find.Therefore, LTE-A system needs extending user equipment (User Equipment, referred to as UE) operable bandwidth, introduced thus carrier aggregation (Carrier Aggregation, referred to as CA) technology, be about to a plurality of continuous or discrete carrier aggregation under same base station (enhanced Node Base Station, referred to as eNB) together, simultaneously for UE service, so that required speed to be provided.
In LTE-A system, UE can pass through a plurality of component carriers (Component Carriers after entering connection status simultaneously, referred to as CCs) communicate with base station, comprising a principal component carrier wave (Primary Component Carrier, referred to as PCC), with several auxiliary component carriers (Secondary Component Carrier, referred to as SCC), the Serving cell of their correspondences is called main Serving cell or main plot (Primary Cell, referred to as PCell) and auxiliary serving cell Huo Fu community (Secondary Cell, referred to as SCell).For convenience of description, in the application, will no longer distinguish the difference of PCC and PCell, SCC and SCell, and they are regarded as to same concept.That is to say, what PCC and PCell represented is same concept, i.e. principal component carrier wave, main Serving cell or main plot; What SCC and SCell represented is same concept, i.e. auxiliary component carrier, auxiliary serving cell Huo Fu community; Component carrier or Serving cell are as the general designation of PCC and PCell, SCC and SCell concept.Wherein, main plot provides Non-Access Stratum (NonAccess Stratum, referred to as NAS) information (as cellular global identity (Cell Global Identification), tracking area identification (TrackingArea Identity) etc.).Only when Radio Link Failure (Radio Link Failure, referred to as RLF) occurs PCell, trigger UE and rebuild chain, SCell can not trigger UE and rebuild chain while there is RLF.
Base station can be by sending media access control unit (MediumAccess Control Control Element to UE, referred to as MAC CE) SCell of activation/deactivation UE configuration, UE safeguards Yi Gefu community deexcitation timer (sCell Deactivation Timer) for each SCell in addition, this timer expired, the SCell that UE deexcitation is relevant; The PCell of UE activates all the time.Base station is by sending the SCell of wireless resource control connection reconfiguration message (RRC Connection Reconfiguration message) release/add/modification UE configuration to UE.
At cognitive radio (Cognitive Radio, referred to as CR) in, the mode use authority frequency range that cognitive radio system can " be waited for an opportunity " according to certain, research shows that the utilance of current television spectrum is not high, therefore, cognitive radio system can " wait for an opportunity " to use primary user's (television broadcasting system) there is no the channel using, i.e. TV idle frequency spectrum (Television White Space, referred to as TVWS) at special time and position.The operable TVWS carrier wave of specific location area is constantly to change, for example, due to primary user's arrival (being that primary user resumes TVWS) or other reason, cognitive radio system must exit the TVWS carrier wave using, or reprovision is to other TVWS carrier wave.
TVWS is as frequency domain resource, and the component carrier that can be configured in CA is equally used.Consider in cognitive radio system, TVWS can be subject to the impact of the events such as primary user arrives, load of base station alleviates, and must " abdicate " the TVWS resource of using, for example, because these events (: primary user arrives) are all high priorities; That is to say, TVWS frequency domain resource is used as the component carrier of CA, is (for example: priority arrives lower than primary user) of lower priority, is unsettled; Therefore, base station configuration Liao Yige community (this community use be TVWS frequency domain resource), and the component carrier that this community is configured to UE is used, this use may be potential a kind of risk, that is to say that base station can delete this community at any time, thereby stop this community as the use of component carrier.
In prior art, base station, in deleting component carrier process, is UE not to be carried out (control comprises: notify UE, change the operation behavior of UE etc.) of corresponding control, that is to say, when delete after component carrier base station, angle from UE, UE does not also know that this component carrier deletes, UE still can carry out according to the method for prior art: monitor physical downlink control channel (Physical Downlink Control Channel, referred to as PDCCH) information, measure and reporting channel quality sign (Channel Quality Indicator, referred to as CQI)/pre-coding matrix indication (Precoding Matrix Indicator, referred to as PMI)/order indication (Rank Indication, referred to as RI)/precoding type indication (Precoding Type Indicator, referred to as PTI) information, and these measurements and report always and can carry out, until base station by RRC Connection Reconfiguration message to measuring and reporting object again to configure.Yet, it is evident that, corresponding component carrier has been deleted in base station, and this monitoring of UE PDCCH, to measure, report be a kind of idle exercise, and the such operation of UE only can expend the energy content of battery of self, but there is no actual application value.And prior art does not have, for UE, this insignificant operation provides corresponding solution.
For delete corresponding component carrier in base station in correlation technique in the situation that, the operation that UE still repeats to monitor PDCCH, measure, report causes expends the problem of self energy content of battery, not yet proposes at present effective solution.
