Technical field
The present invention relates to the communications field, in particular to a kind of data transmission method for mixed time division duplex large band width system.
Background technology
Fig. 1 shows the frame structure of LTE (Long Term Evolution, Long Term Evolution) system TDD (Time DivisionDuplex, time division duplex) pattern.In the frame structure of tdd mode, the radioframe of a 10ms (radio frames) is long for the half frame (field) of 5ms forms by two, and field comprises 5 and longly is the subframe of 1ms (subframe).Subframe i is defined as 2 and longly is time slot 2i and the 2i+1 of 0.5ms.For Normal CP (Normal Cyclic Prefix, standard cyclic prefix), the symbol that it is 66.7us that time slot comprises 7 length, wherein the CP length of first symbol is 5.21us, the CP of all the other 6 symbols (Cyclic Prefix) length is 4.69us; For Extended (Extended, expansion) CP, a time slot comprises 6 symbols, and the CP length of all symbols is 16.67us.
In this frame structure, the configuration characteristics of subframe are:
(1) on/and downlink percent configuration (UL/DL ratio configuration): in order to reduce the configured number of up-downgoing ratio, LTE TDD has stipulated the allocation plan of 7 kinds of ascending-descending subframes numbers in a radio frames, sees Table 1.All subframes all are divided into three classes, the one, descending sub frame; The one, special subframe; The one, sub-frame of uplink; In allocation plan 1, subframe 2,3,7,8 are used for uplink, subframe 0,4,5,9 are used for downlink transfer, and subframe 1,6 is a special subframe simultaneously.
Table 1LTE TDD up-downgoing proportional arrangement
Wherein, D represents descending sub frame, and U represents sub-frame of uplink, and S represents special subframe.
(2) special subframe comprises 3 special time slots, is respectively DwPTS (Downlink Pilot TimeSlot, descending pilot frequency time slot), GP (Guard Period, protection is at interval) and UpPTS (Uplink PilotTime Slot, uplink pilot time slot), wherein:
1. DwPTS is used for downlink transfer, minimumly comprises three symbols, and the 3rd symbol is used to transmit P-SCH (Primary-Synchronization, synchronously main) signal;
2. GP does not transmit any data for the protection interval;
3. UpPTS is used for uplink, can be used to transmit signals such as RACH (Random Access Channel, Random Access Channel), sounding (detection) pilot tone;
(3) the previous subframe of special subframe is fixed for downlink transfer; A back subframe of special subframe is fixed for uplink.
LTE Release-8 has defined 6 kinds of bandwidth: 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and has known 20MHz;
LTE-Advanced (Further Advancements for E-UTRA) is the evolution version of LTE Release-8.Except that satisfying or surpassing 3GPP TR 25.913: all related needs of " Requirements for Evolved UTRA (E-UTRA) and Evolved UTRAN (E-UTRAN) ", also will meet or exceed the demand of the IMT-Advanced of ITU-R proposition.Wherein, the demand with LTE Release-8 backward compatibility is meant: the terminal of LTE Release-8 can be worked in the network of LTE-Advanced; The terminal of LTE-Advanced can be worked in the network of LTE Release-8.
In addition, LTE-Advanced should be able to satisfy more flexible bigger frequency spectrum configuration, is supported in the wideer frequency spectrum configuration (as 50Mhz, the system spectral resources of 100MHz) of LTERelease-8 work down, to reach higher performance and target peak speed.Because the LTE-Advanced network needs to insert LTE user, so its operational frequency bands need cover present LTE frequency band, has not had the spectral bandwidth of assignable continuous 100MHz on this frequency range.So in order to support the bigger system bandwidth of 20Mhz, the direct technology that LTE-Advanced need solve is that several composition carrier frequency resource (the Component frequency resource) polymerizations that are distributed on the different frequency range are got up to form the operable big system bandwidth resource of LTE-Advanced, the carrier frequency difference of every composition carrier frequency resource (centre frequency difference), the amount of bandwidth of every composition carrier frequency resource can be different, every composition carrier frequency resource comprises a continuous sub-carriers group, be that every composition carrier frequency resource is a continuous frequency spectrum resource, system bandwidth as 100Mhz can be polymerized by the composition carrier frequency resource that 5 bandwidth are 20Mhz, and the composition carrier frequency resource that also can be added two 20Mhz by the composition carrier frequency resource of a 60Mhz is polymerized.Just, the big system bandwidth of LTE-Advanced demand can be polymerized by n piece composition carrier frequency resource, the carrier frequency difference of every composition carrier frequency resource, the big system bandwidth that is polymerization comprises n one-tenth sub-carrier (Component carrier), and the amount of bandwidth of the composition carrier frequency resource of each composition carriers carry can be different.
The scheme of frequency spectrum configuration mainly contains 3 kinds, as shown in Figure 2.Wherein, the one-tenth sub-carrier of grid part is and the system bandwidth of LTE Release-8 compatibility that the one-tenth sub-carrier of oblique line part is the proprietary system bandwidth of LTE-Advanced.Fig. 2 a is a frequency spectrum allocation plan 1, be meant that the LTE-Advanced frequency spectrum disposes the system bandwidth that is defined by 1 LTE-Advanced and forms, and this bandwidth is greater than the system bandwidth of LTE Release-8 definition.Fig. 2 b is a frequency spectrum allocation plan 2, is meant that the LTE-Advanced frequency spectrum disposes the system component carrier wave that is defined by a LTERelease-8 and forms by spectrum aggregating (carrier aggregation) with the sub-carrier that becomes of a plurality of LTE-Advanced definition.Fig. 2 c is a frequency spectrum allocation plan 3, be meant that the LTE-Advanced frequency spectrum disposes the system component carrier wave that is defined by a plurality of LTE Release-8 and forms by spectrum aggregating (carrieraggregation), wherein, the gathering of above-mentioned frequency spectrum can be the polymerization of continuous frequency spectrum, also can be the polymerization of discontinuous spectrum.LTE Release-8 terminal can insert the frequency band of compatible LTE Release-8, and the LTE-A terminal can either insert the frequency band of LTE Release-8 compatibility, also can insert the frequency band of LTE-Advanced.
Consider and the compatibility of LTE Release-8 that LTE-Advanced respectively becomes sub-carrier to need to satisfy can insert LTE user; In addition, be subjected to hardware device restriction, at present and in the coming years, up emission surpasses the 40MHz bandwidth signal will consume a large amount of power, be unfavorable for terminal power saving; The downlink business flow will significantly increase in the wireless network simultaneously, causes terminal up-downgoing business asymmetric; And for a plurality of composition carrier aggregation of discontinuous frequency spectrum, each composition spectrum of carrier characteristic is may difference very big.The LTE-Advanced system need satisfy above-mentioned to time delay, and high-throughput/spectral efficient is supported the non-symmetrical service type, requirements such as backward compatibility.
