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 abbreviates LTE as) system supports time division duplex (Time Division Duplex abbreviates TDD as).Fig. 1 is the frame structure sketch map according to the TDD of correlation technique; As shown in Figure 1; On time domain, each radio frames is 10ms, forms (being that each field is 5ms) by 2 fields (half-frame); Each field is formed (being that each subframe is 1ms) by 5 sub-frame, and each subframe is formed (being that each time slot is 0.5ms) by 2 time slots (slot).On frequency domain; Up link adopts identical frequency band timesharing to transmit with down link; According to the needs of business, system can be used for uplink with the part subframe (being sub-frame of uplink) of radio frames according to certain ratio, and part subframe (being descending sub frame) is used for downlink transfer.According to the needs of different regions type of service, select suitable up-downgoing proportional arrangement to help improving the spectrum efficiency of TDD system.Such as, for the more area of downlink business, just can select the more configuration of descending sub frame; For the more area of uplink service, just can select the more configuration of sub-frame of uplink; For the area of up-downgoing business, just can select the subequal proportional arrangement of ascending-descending subframes than balance.Totally 7 kinds of the TDD proportion of ascending subframe and descending subframe that the long evolving system of time division duplex (Time Division Duplex Long-Term Evolution abbreviates TD-LTE as) system supports, as shown in table 1.The interior subframe of radio frames is labeled as respectively: 0,1,2,3,4,5,6,7,8,9." D " representes that this subframe is a descending sub frame; " U " representes that this subframe is a sub-frame of uplink; " S " representes that this subframe is a special subframe, and being used to be illustrated in this subframe subframe before is descending sub frame, and the subframe after this subframe is a sub-frame of uplink.Cycle in the table refers to the cycle of special subframe, if all there is special subframe in 2 fields in each radio frames, then the cycle is 5ms; If have only 1 field to have special subframe in each radio frames, then the cycle is 10ms.

The uplink-downlink configuration signal table that table 1TD-LTE system supports

Subscriber equipment (User Equipment; Abbreviating UE as) process of downlink data receiving comprises: UE monitors Physical Downlink Control Channel (Physical Downlink Control Channel; Abbreviate PDCCH as); According to (the Downlink Control Information of the Downlink Control Information that is used for this UE on the PDCCH; Abbreviate DCI as) Physical Downlink Shared Channel (Physical Downlink Shared Channel, the be called for short PDSCH) downlink data receiving of the same subframe of decoding, and receives successfully to base station feedback and perhaps to fail.Because the ascending-descending subframes of different uplink-downlink configuration distributes different in the TD-LTE system; Therefore the sequential of different configurations is different; Suppose that UE receives PDCCH/PDSCH at subframe n, receive successfully or fail in subframe (n+k) feedback, for different uplink-downlink configuration, different subframe n; The value of k is different, and is as shown in table 2.

The descending sequential signal table of table 2TD-LTE system

The process that UE sends upstream data comprises: UE monitors Physical Downlink Control Channel (Physical Downlink Control Channel; Abbreviate PDCCH as); According to the Downlink Control Information that is used for said UE (the DownlinkControl Information on the PDCCH; Abbreviate DCI as), send upstream data at Physical Uplink Shared Channel (Physical Uplink Shared Channel is called for short PUSCH).Because the distribution of the ascending-descending subframes of different uplink-downlink configuration is different in the TD-LTE system, therefore the sequential of different configurations difference supposes that UE receives PDCCH at subframe n; Send PUSCH in subframe (n+k); For different uplink-downlink configuration, different subframe n, the value of k is different, and is as shown in table 3.

The up sequential signal table of table 3TD-LTE system

Under the situation of uplink service that burst occurs or downlink business, if uplink-downlink configuration can not the professional ratio demand of adaptive up-downgoing, uplink-downlink configuration need be adjusted in the base station.At present; The base station notifies the UE uplink-downlink configuration to change through the mode of system message update; Can not upgrade continually owing to system message on the one hand; Because system message is not an immediate updating, indication UE system message update causes certain delay to bringing into use the minimum 640ms of needs of new uplink-downlink configuration from the base station on the other hand; Therefore, the data transmission method in the correlation technique is because the uplink service of burst or downlink business cause frequent uplink-downlink configuration adjustment to cause the performance of transfer of data poor.

Notify the UE uplink-downlink configuration to change the uplink service or the downlink business that can't satisfy burst to the data transmission method in the correlation technique through the mode of system message update; Cause the poor problem of performance of transfer of data, do not propose effective solution at present as yet.

Summary of the invention
