Description
Technical field
The present invention relates to the communications field, in particular to a kind of transmission timing method and device of uplink authorization signaling.
Background technology
As shown in Figure 1, be LTE (Long Term Evolution, Long Term Evolution) system TDD (Time Division Duplex, time division duplex) frame structure of pattern, in this frame structure, the radio frame (radio frames) of a 10ms is divided into two half frame (field), the time slot that it is 0.5ms that each field is divided into 10 length, two time slots form the subframe that length is 1ms, then comprise 5 subframes in a field.In this frame structure, the preparation characteristics of subframe are:
(1) subframe 0 is fixed for descending;
(2) subframe 1 (hereinafter referred to as the special time slot subframe) comprises 3 special time slots; respectively DwPTS (Downlink Pilot Time Slot; descending pilot frequency time slot), GP (GuardPeriod; protect the interval) and UpPTS (Uplink Pilot Time Slot; uplink pilot time slot), wherein:
1. DwPTS can transmit the signals such as P-SCH (Primary-SynchronizationChannel, primary synchronization channel), PDSCH (Physical Downlink Share Channel, Physical Downlink Shared Channel) for descending; And
2. GP is guard time, does not transmit any data; And
3. UpPTS can be used for the signals such as transmission RACH (Random AccessChannel, Random Access Channel), sounding (detection) pilot tone for up; And
(3) subframe 2 is fixed for uplink.
Table 1 shows 7 kinds of ascending-descending subframes configurations of present LTE TDD configuration.For example configuring at 1 o'clock, subframe 2,3,7,8 are used for uplink, subframe 0,4,5,9 are used for downlink transfer, and the DwPTS part symbol in the special time slot subframe 1,6 also is used for downlink transfer simultaneously.
Table 1LTE TDD configuring condition

*) DL/D: descending, UL/U: up, S: special time slot subframe
Owing to adopting synchronous HARQ (Hybird-ARQ, the mixed automatic retransfer request) transmission, uplink ACK (Acknowledgement correctly replys) and NACK (Negative-Acknowledgement, wrong responses) transmit timing need pre-configured.The LTE regulation, up response message and uplink authorization information send at same descending sub frame.Because hardware handles postpones, for the TDD system, the uplink authorization information that UE (User Equipment, subscriber equipment) receives at subframe n is used to indicate the data that send at subframe n+k (k＞3).
At some application scenarios, such as the large coverage cell configuration of suburbs and counties under the jurisdiction of a large city, the up covering problem that probably occurs, i.e. the signal of UE full power emission arrives base station side still can not be by correct decoding.For effectively solving the problem of up covering, to improve service quality, the LTE tdd mode has been introduced the concept of TTI (Transmission Time Interval, Transmission Time Interval) bundling (binding).The basic principle of TTI bundling is that continuous a plurality of subframe running time-frequency resources are all dispatched to same travelling carriage, and this travelling carriage is in the same load of continuous subframes transmission of each distribution.Owing to transmitting continuously a plurality of copies of identical information, improved the signal to noise ratio of base station combined signal, improved covering power.TTI bundling definition continuously N subframe of transmission is a packing binding (bundle), and binding size (bundle size) is N.Because TDD system retransmission delay time is larger, the introducing of TTI bundling pattern just seems particularly important to the service quality that satisfies delay sensitive class business.
Fig. 2 shows the HARQ ideograph of LTE system TDD mode; HARQ when Fig. 3 shows the up employing of LTE system TDD mode TTI bundling retransmits schematic diagram.Behind the LTE definition of T TI bundling, HARQ is at corresponding last sub-frame of uplink of packing and binding together of the response message of descending transmission at present.Detailed, if last sub-frame of uplink that packing binds together is subframe k, the re-transmission of its HARQ is transmitted (Round-Trip Time, round-trip delay) at subframe k+2 * HARQ RTT so.
In realizing process of the present invention, after the inventor finds to adopt TTI bundling pattern, the response message of HARQ, dispatch, re-transmission timing etc. all can change, response message any one descending sub frame transmission after upstream data is handled in the base station and before the HARQ re-transmission can, and prior art does not also propose for above-mentioned situation, in the up TTIbundling transmission mode in the method for up transmission authorization signaling.
