Description

Base station state management method, equipment and system

Technical field

The present invention relates to the communication technology, particularly relate to a kind of base station state management method, equipment and system.

Background technology

Long Term Evolution (LTE, Long Term Evolution) project is G mobile communication (3G, Third Generation) evolution, it improves and enhances the aerial access technology of 3G, it adopts OFDM (OFDM, Orthogonal Frequency Division Multiplexing) technology and multiple-input and multiple-output (MIMO, Multiple Inputs and Multiple Outputs) technology, that is: multi-antenna technology is as the sole criterion of wireless network evolution.Senior Long Term Evolution (LTE-A, LTE-Advanced) is the follow-up evolution of LTE technology.In order to meet the various demand parameters of 4G, the several key technologies for LTE-A are suggested, and comprise carrier aggregation, coordinate multipoint transmission and reception, relay transmission and multiple antennas enhancing etc.

Heterogeneous network system is a kind of novel network architecture proposed in LTE, in this new framework, multiple maximum transmission power can be settled in the geographical coverage area of a macro base station (Macro Cell) lower and the little base station (Small Cell) that overlay area is less, in a macro base station coverage area, little base station more close for geographical position can be considered as one bunch (Cluster), little base station mainly can be divided into two large classes: a class is placed in outdoor, is called femto base station (Pico), an other class is placed in indoor, be called Home eNodeB (HeNB, Home eNodeB), if the negligible amounts of the little base station of placing in a macro base station coverage area, within such as four, then be regarded as the sparse deployment scenario in little base station, although the interference under this scene between little base station still exists, but not main interference, it mainly disturbs from macro base station, in the prior art, almost blank subframe (ABS is proposed for the sparse deployment scenario in little base station, Almost BlankSubframe) technology, this technology proposes the base station of strong jamming type, such as macro base station does not send data in the subframe of configuration, to reduce little base station, femto base station has cell edge user terminal (UE under its command, UserEquipment) interference.

If the quantity of the little base station of placing in a macro base station coverage area is more, such as more than ten, then be regarded as little base station dense deployment scene, interference under this scene between little base station can be quite serious, ABS technology is adopted to be difficult to solve interference problem under this scene simply, be compatible carrier wave (BCT in existing carrier type, Backward Carrier Type), no matter send with or without data, each subframe must send public reference signal (CRS, Common Reference Signal), otherwise user terminal None-identified.So not only waste resource, simultaneously owing to increasing base station transmitting power, also interference is caused to other base stations.

Therefore, correlation technique proposes the carrier type (NBCT of newly-increased a kind of non-backward compatible, NonBackward carrier type) carrier wave, be also called new carrier type (NCT, New Carrier Type) carrier wave or expansion carrier type carrier wave, be primarily characterized in that CRS can not send in each subframe in the type carrier wave, such as can send once (the preferred value of N is 5) every N number of subframe, or in time having data to send, just send CRS, just CRS is not sent out when not having data to send, therefore when needing without downlink data to send, NCT carrier wave can not send any data without in the subframe of CRS, compare BCT, NCT has the lower characteristic of the higher power consumption of spectrum efficiency, and it is less to the interference of adjacent area, for expansion carrier wave, different frequency resource block can be taked different transmission forms and technology, but NCT carrier wave does not have backwards compatibility, namely mean can not be all user terminal identification.

Consider that NCT carrier wave etc. can not be a kind of Novel carrier wave for the carrier wave of all user terminal identification, be only applicable to the user terminal that part has response carrier wave recognition capability, namely not there is backwards compatibility, and the user terminal with corresponding recognition capability needs time from extensive popularizing of coming into operation, therefore NCT carrier wave etc. will can not coexist for the carrier wave of all user terminal identification and BCT carrier wave within one period, and consider that NCT carrier wave etc. can not be the advantage of the carrier wave of all user terminal identification, need base station to use in practical application as far as possible, but when base station to have under its command in community most for not there is this carrier wave recognition capability user terminal time, if now base station still adopts NCT carrier wave etc. can not send data for the carrier wave of all user terminal identification, the wasting of resources can be caused.

In sum, for when NCT carrier wave etc. can not coexist for the carrier wave of all user terminal identification and BCT carrier wave, how to promote the availability of frequency spectrum, reduce interference, save power consumption and do not waste resource, correlation technique there is no solution.

Summary of the invention
