Abstract
The invention discloses a service data transmission method and apparatus for solving the problems of relatively low success rate of data transmission and poor user experience of a method for UE achieving transmission in an LTE-U carrier cell by means of carrier aggregation in the prior art. The method of the invention comprises that a transmitting device transmits service data through a first cell in an unlicensed spectrum; the transmitting device determines a second cell after determining that the first cell cannot meet the transmission requirement of the service data; and the transmitting device transmits the service data through the determined second cell. Since another cell is determined for transmitting the service data in the embodiment of the invention when the cell in the unlicensed spectrum cannot meet the transmission requirement of the service data, the success rate of data transmission is increased, and thus the user experience is improved.

In prior art, frequency spectrum can be divided into mandate frequency spectrum and unlicensed spectrum.Wherein, authorizing frequency spectrum is ready-portioned special frequency spectrum, its interference can be predicted substantially, and unlicensed spectrum is not planned concrete application system, can share for multiple systems, such as LTE (LongTermEvolution, Long Term Evolution), WiFi (wireless network) etc., therefore, its interference is unpredictable, there is very big uncertainty in transmission performance and the service quality of the transmission of its data, when the interference of unlicensed spectrum is less, transmission performance and service quality can be accepted, when the interference of unlicensed spectrum is bigger, then can reduce data transmission performance, cause that service quality declines.
Along with the continuous growth of mobile data services amount, LTE system starts to consider to dispose transmission in unlicensed spectrum resource, to improve Consumer's Experience.But, owing to unlicensed spectrum resource can be shared by multiple systems, therefore LTE system disturbed condition in unlicensed spectrum resource is more unstable.
At present, one realizes UE (UserEquipment by carrier aggregation mode, user terminal) at LTE-U (LTE-unlicensed, the carrier wave of the unauthorized frequency range of LTE) method that is transmitted on carrier cell is: using the community in LTE-U frequency range as CA (CarrierAggregation, carrier aggregation) under SCell (SecondaryCell, secondary cell) use；For the situation of the interference dynamic instability in LTE-U frequency range, network activates deexcitation mechanism by SCell, or SCellon/off mechanism stops at and provides business transmission service for this UE on this community.When SCelloff or deexcitation time, it is data cached that UE side can empty HARQ (HybridAutomaticRepeatRequest, hybrid automatic repeat-request) corresponding on this SCell, stops the transmission of all up-downgoing data or signal.
In prior art, owing to the activation deexcitation frequency of LTE-USCell is higher, can cause that the probability that MAC thereon (MediumAccessControl, medium education) HARQ data empties improves, thus reducing the success rate of business data transmission.Even if RLC is (RadioLinkControl, wireless spread-spectrum technology) ARQ (AutomaticRepeatRequest, HARQ) mechanism can ensure that the effectiveness that business is transmitted, when the HARQ data in LTE-U community is often cleared, also the propagation delay time of rlc layer can be extended, strengthen rlc layer and the generation of fatal error occurs, thus causing that user's connects the generation that needs re-establish.
