Abstract
The invention provides a service detection method when an LTE system works in a non-authorized frequency band, a service detection system when the LTE system works in a non-authorized frequency band, a terminal and a base station. The service detection method when the LTE system works in the non-authorized frequency band comprises steps: whether a target detection signal exists on the current sub frame in the non-authorized frequency band is detected to determine whether the base station providing service for the terminal occupies an idle channel already; when the target detection signal is detected, the base station is determined to already occupy the idle channel to enable the base station to execute service scheduling in the non-authorized frequency band; and when the target detection signal is not detected, whether the target detection signal exists on a sub frame after the current sub frame is detected continuously. According to the technical scheme of the invention, the energy consumption of the terminal can be effectively reduced, the position of the base station successfully occupying the channel can be accurately acquired while energy conservation is achieved, and the terminal can be effectively prevented from missing the scheduling chance.
Description
Technical field
The present invention relates to communication technical field, in particular to a kind of LTE system unauthorizedService testing method when frequency range work, the business of a kind of LTE system in the time of unauthorized frequency range workDetection system, a kind of terminal and a kind of base station.
Background technology
At present, along with the fast development of mobile service, the existing wireless frequency spectrum of distributing to mobile serviceCapacity cannot meet the demands. At 3GPP (The3rdGenerationPartnershipProject，3G (Third Generation) Moblie partnership) the Rel-13 stage, one is called LAA (LicensedAssistedAccess, auxiliary access technology) mechanism be introduced into. In LAA mechanism, the biography of mobile communicationDefeated can carrying in unlicensed spectrum, as the frequency range of 5GHz. These unlicensed spectrum, are mainly at presentThe systems such as WIFI, bluetooth, radar, medical treatment are being used.
Due to diversity and the complexity of system in unlicensed spectrum, directly LTE (LongTermEvolution, Long Term Evolution) mechanism in unlicensed spectrum, be the security that cannot ensure user withAnd the stability connecting. Therefore, in the mechanism of LAA, by CA (CarrierAggregation, carrier aggregation) mechanism, use authority frequency spectrum is helped the access in unlicensed spectrum.At present, in unlicensed spectrum, use LTE to have two kinds of working methods, one be supplement descending (SDL,SupplementalDownlink), only has downlink transfer subframe; Another kind is tdd mode, bothComprise downlink transfer subframe, also comprise uplink subframe, as shown in Figure 1.
In unlicensed spectrum, between multiple systems, need competition to use resource, for the public affairs between guarantee systemFlat sharing, the mechanism (LBT, ListenBeforeTalk) that one is called " listem-before-talk " is introduced into. That is to say that whether competition is used the system of resource before busy channel, to need monitor channelShared by other system. If channel is idle, this system just can be removed busy channel so.If channel is busy, this system cannot busy channel so. At present, existing two kinds of LBT mechanism,One is FBE (Framebasedequipment, based on the equipment of frame structure), and one is LBE(Loadbasedequipment, based on the equipment of load). The in the situation that of FBE, need by pre-Fixed cycle carries out channel idle whether detection; The in the situation that of LBE, can be according to the Demand of businessThe whether detection of Shi Faqi channel idle.
At present, terminal energy-conservation becomes a problem demanding prompt solution. Consider at smallcell (littleType base station) scene under, because the on off state of smallcell may change comparatively frequently, because ofThis, if the terminal of being served by smallcell, always in connection status, need to be gone inspection at each frameThe transmission of surveying data, can bring higher energy consumption thus.
For addressing the above problem, the scheme that some terminals detect has been proposed, such as, can lead by detectionFrequently whether the existence of signal judges on this frame, whether terminal needs to do Data Detection, but, award non-On power frequency spectrum, especially, the in the situation that of LBE, whether pilot signal exists and depends on Channel Detection is at whichOn individual position, when success, detect channel idle, therefore, may affect terminal and carry out data inspectionThe accuracy of surveying; Or, can be by serving BS via this serving BS of physical layer signaling notification terminalThe subframe set of opening, but cannot be applied to equally in unauthorized frequency range, equally also under this methodBecause base station cannot learn whether Channel Detection can be successful. .
Therefore, need a kind of method that terminal detects of waking up that is applied to unauthorized frequency range, with effectivelyThe terminal of avoiding miss dispatcher meeting, and avoid consuming more energy, reach energy-conservation object.
Summary of the invention
The present invention, just based on the problems referred to above, has proposed a kind of new technical scheme, can effectively subtractThe energy consumption of few terminal can know accurately that base station successfully takies in reaching energy-conservation objectThe position of channel, thus effectively avoid terminal to miss dispatcher meeting.
