Description
Technical field
The present invention relates in wireless communication system the scheme utilizing unlicensed spectrum to communicate, particularly relate to the communication means based on LTE (LongTermEvolution, Long Term Evolution) and device.
Background technology
Traditional 3GPP (3rdGenerationPartnerProject, third generation partner program) in LTE system, transfer of data can only occur in authorizes on frequency spectrum (LicensedSpectrum), but along with the sharply increase of traffic carrying capacity, especially in some urban areas, frequency spectrum is authorized may to be difficult to the demand meeting traffic carrying capacity.3GPPRAN (RadioAccessNetwork, wireless access network) 62 plenary sessions discuss a new research topic, namely the research (RP-132085) that unlicensed spectrum is comprehensive, main purpose is that the dependent (Non-standalone) of the LTE of research and utilization in unlicensed spectrum is disposed, and so-called dependent refers to that the communication in unlicensed spectrum is wanted and authorizes the Serving cell on frequency spectrum to be associated.One intuitively method be the CA (CarrierAggregation reused as far as possible in existing system, carrier aggregation) concept, namely be deployed in and authorize Serving cell on frequency spectrum as PCC (PrimaryComponentCarrier, main carrier), be deployed in Serving cell in unlicensed spectrum as SCC (SecondaryComponentCarrier, auxiliary carrier wave).In RAN#64 plenary session (seminar), the communication in unlicensed spectrum is LAA (LicenseAssistedAccess authorizes the auxiliary access of frequency spectrum) by Uniform Name.
3GPPR (Release, version) introduce eIMTA (enhancedInterferenceManagementTrafficAdaptation in 12, the interference management service adaptation strengthened) technology, namely for TDD (TimeDivisionDuplex, time division duplex) UL (Uplink, up)/DL (Downlink, descending) frame structure, can adjust TDDUL/DL frame structure by dynamic signaling, possible TDDUL/DL frame structure comprises the #0 ~ 6 totally 7 kinds of tdd frame structures defined in LTE.
For unlicensed spectrum (UnlicensedSpectrum), one than eIMTA more flexibly scheme be DD (DynamicDuplex), namely each subframe can be set to descending sub frame or sub-frame of uplink dynamically.Need between descending sub frame and sub-frame of uplink to arrange GP (GuardPeriod, protection interval) to hold propagation delay, and the decline that GP can bring efficiency of transmission is set too much.In addition, consider that LBT (ListenBeforeTalk intercepts rear transmission) is probably applied to unlicensed spectrum, GP can be used to interference and intercept.In DD scene, one needs the problem solved to be how to arrange GP can meet the decline that communication requirement avoids (such as hold propagation delay, disturb demands such as intercepting) efficiency of transmission simultaneously.For DD, one intuitively scheme be that each subframe all distributes GP resource, but the program has following problem:
-waste resource is such as do not need GP between two continuous descending sub frames
-be unfavorable for that interference is intercepted, if two adjacent base stations such as disposed by different operators keep synchronizing sub-frame and arrange GP in the same position of each subframe, then described two adjacent base stations cannot intercept interference.
