Description

Data transmission method, apparatus and system
Technical field
The present invention relates to the communications field, in particular to a kind of data transmission method, apparatus and system.
Background technology
Long Term Evolution (Long-Term Evolution, referred to as LTE) system supports time division duplex (Time Division Duplex, referred to as TDD).Fig. 1 is the frame structure schematic diagram of the TDD according to correlation technique, as shown in figure 1, In time domain, each radio frames is 10ms, be made up of 2 fields (half-frame) (i.e. each field is 5ms), each field by 5 subframe compositions (being that each subframe is 1ms), each subframe constitutes (i.e. each time slot is 0.5ms) by 2 time slots (slot). On frequency domain, up-link and downlink are transmitted using identical frequency band timesharing, and according to the needs of business, system can be with The part subframe (i.e. sub-frame of uplink) of radio frames is used for uplink, part subframe (i.e. descending sub frame) according to certain ratio For downlink transfer.According to the needs of different regions type of service, suitable up-downgoing proportional arrangement is selected to be conducive to improving TDD The spectrum efficiency of system.Such as, for the area that downlink business is more, it is possible to select the configuration that descending sub frame is more；For The more area of uplink service, it is possible to select the configuration that sub-frame of uplink is more；For up-downgoing business compared with balance area, just The subequal proportional arrangement of ascending-descending subframes can be selected.Long evolving system (the Time Division of time division duplex Duplex Long-Term Evolution, referred to as TD-LTE) system support TDD ascending-descending subframes totally 7 kinds of ratio, such as Shown in table 1.The subframe of one wireless frame in is respectively labeled as：0,1,2,3,4,5,6,7,8,9." D " represents that the subframe is descending Subframe；" U " represents that the subframe is sub-frame of uplink；" S " represents the subframe for special subframe, for representing the son before the subframe Frame is descending sub frame, and the subframe after the subframe is sub-frame of uplink.Cycle in table refers to the cycle of special subframe, if per In individual radio frames all there is special subframe in 2 fields, then the cycle is 5ms；If it is special to only have 1 field to exist in each radio frames Subframe, then the cycle is 10ms.
The uplink-downlink configuration that table 1TD-LTE systems are supported illustrates table
User equipment (User Equipment, referred to as UE) receives the process of downlink data to be included：UE is monitored under physics Row control channel (Physical Downlink Control Channel, referred to as PDCCH), according on PDCCH for this The Downlink Control Information (Downlink Control Information, referred to as DCI) of UE is decoded under the physics of same subframe Row shared channel (Physical Downlink Shared Channel, abbreviation PDSCH) receives downlink data, and anti-to base station Feedback is received successfully or is failed.As the ascending-descending subframes of different uplink-downlink configurations in TD-LTE system are distributed difference, therefore Different configuration of sequential is different, it is assumed that UE receives PDCCH/PDSCH in subframe n, in the success of subframe (n+k) feedback reception or mistake Lose, for different uplink-downlink configurations, different subframes n, the value of k is different, as shown in table 2.
The descending sequential of table 2TD-LTE systems illustrates table
UE sends the process of upstream data to be included：UE monitors Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as PDCCH), according to the Downlink Control Information for the UE on PDCCH (DownlinkControl Information, referred to as DCI), physically row shared channel (Physical Uplink Shared Channel, abbreviation PUSCH) send upstream data.Upper and lower due to different uplink-downlink configurations in TD-LTE system Row subframe distribution is different, and therefore different configuration of sequential is different, it is assumed that UE receives PDCCH in subframe n, sends in subframe (n+k) PUSCH, for different uplink-downlink configurations, different subframes n, the value of k is different, as shown in table 3.
The up sequential of table 3TD-LTE systems illustrates table
In the case of the uplink service or downlink business for burst occur, if uplink-downlink configuration can not be adapted to up-downgoing The ratio demand of business, base station need to adjust uplink-downlink configuration.At present, base station is notified on UE by way of system message update Downstream arrangements change, on the one hand as system message continually can not update, on the other hand as system message is not immediately more New, indicate that new uplink-downlink configuration is minimum to need 640ms to UE system message updates to beginning to use, and causes certain from base station Postpone, therefore, data transmission method in correlation technique is caused frequently up and down due to the uplink service that happens suddenly or downlink business Row configuration adjustment causes the Performance comparision of data transfer poor.
Data transmission method in for correlation technique notifies UE uplink-downlink configurations to become by way of system message update Change the uplink service or downlink business that cannot meet burst, cause the problem of the Performance comparision difference of data transfer, at present not yet Propose effective solution.
Content of the invention
Present invention is primarily targeted at a kind of data transmission method, apparatus and system are provided, at least to solve above-mentioned phase Data transmission method in the technology of pass notifies the change of UE uplink-downlink configurations meet burst by way of system message update Uplink service or downlink business, cause data transfer Performance comparision difference problem.
