Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to the uplink resource scheduling technology of a kind of TDD of being applied to system.
Background technology
(the 3rd Generation Partnership Project of 3G (Third Generation) Moblie standardization body, 3GPP) started Long Term Evolution (Long Term Evolution, LTE) standardization effort of technology, in the LTE in future technology, adopt shared channel to provide service for a plurality of users, thereby obtain multi-subscriber dispatching and spatial multiplexing gain, improve the availability of frequency spectrum and throughput of system, become the prevailing model that system design is adopted.
In order to support the channel shared by multiple users resource, adopting the method for dynamic dispatching is that UE distributes the resource of transmitting data in real time.Think that below the UE transmit ascending data is an example, provide the dynamic dispatching process of resource, as shown in Figure 1, evolution base station (Evolution Base Station, eNB) be that (User Equipment UE) divides the resource that is used in transmit ascending data to subscriber equipment at first by ascending resource assignment signalling (UL Grant); UE receives behind the UL Grant through handling time-delay Tue, finishes the processing to UL Grant; UE sends upstream data (UL Data) on the resource of UL Grant indication then; After eNB receives the UL Data of UE transmission,, can continue to send the Resources allocation of transmitting uplink data next time that UL Grant is UE through handling time-delay Tenb.
(Time, TDD) in the system, the up-downgoing resource is staggered the appearance at time division duplex.As shown in Figure 2, be a kind of frame structure of possible TDD system, a radio frames (Frame) is made up of two descending sub frames (DL Subframe) and three sub-frame of uplink (UL Subframe), and the length of Subframe is 1ms, and the length of Frame is 5ms.Descending/up switching point (DUSP) is the moment that is transformed to UL Subframe from DLSubframe; Up/descending switching point (UDSP) is the moment that is transformed to DL Subframe from ULSubframe.
When being the UE transmit ascending data in LTE TDD system, because UL Grant is the down direction that sends to UE from eNB, so can only issue in DL Subframe, the ascending resource that being used for of its distribution transmitted UL Data is positioned at UL Subframe.In order to realize ascending resource scheduling flexibly, the LTE technology is introduced the sub-frame of uplink index in UL Grant (UL Subframe Index USI), is used for indicating which UL Subframe of the corresponding radio frames of ascending resource of current distribution.For example at the frame structure of Fig. 2, the corresponding Subframe 2 of USI=0, the rest may be inferred the corresponding Subframe 3 of USI=1, the corresponding Subframe 4 of USI=2.But standard code does not indicate UL Grant to dispatch UL Subframe in which radio frames in UL Grant.The general employing according to handling time-delay determined to dispatch UL Subframe between follow-up K and K+1 the DUSP at the ULGrant of DL Subframe, system is fixed value of K configuration, for example during K=2, as shown in Figure 3, at the UL Grant that the Subframe 0 that is positioned at Frame N and Subframe 1 issue, its USI correspondence be the UL Subframe of Frame N+1.
Feed back re-transmission fast for the data block to loading error occurring, (Hybrid Automatic Repeat Request, HARQ) technology is adopted by a plurality of systems as a kind of solution preferably to mix automatic repeat requests.On the high speed/(High Speed Uplink/DownlinkPacket Access, HSUPA/HSDPA) technology, following LTE technology etc. all adopt that multidiameter delay stops and wait the HARQ agreement to support continuous scheduling and the transmission to data block in the downlink grouped access.Stop waiting be meant use certain HARQ process transmission data block after, before receiving feedback information, can not continue to use other data block of this process transmission; The advantage of stop-and-wait protocol is fairly simple, but efficiency of transmission is lower.Adopt the multidiameter delay stop-and-wait protocol, start a plurality of HARQ processes simultaneously, can remedy the low shortcoming of efficiency of transmission; Its basic thought is to dispose simultaneously a plurality of HARQ processes, in the process of certain HARQ progress feedback information of wait, can use other idle process transmission data block.For the data block of loading error occurring, must use identical HARQ process to retransmit, so that receiving terminal merges the data block of makeing mistakes.According to the moment of retransmit taking place predefine whether, the HARQ agreement can be divided into two kinds of synchronous HARQ and asynchronous HARQ.
Among the asynchronous HARQ, the retransmission time of data block is not predefined, but is dynamically determined by scheduler, therefore needs the HARQ process numbering (ID) that shows that ground notice receiving terminal data block is used; In the synchronous HARQ, the retransmission time of data block is predefined, is carved with fixing sequential relationship during with first biography, and its HARQ process ID can not need explicit signaling consumption by the reaction of timing relationship implicit expression.
In order to simplify the synchronous HARQ scheme in the TDD system, be the time interval (HARQ_RTT) between adjacent twice transmission of HARQ transmission setting that begins from each UL Subframe, and the ULSubframe numbering has binding relationship with the HARQ process ID, and wherein HARQ_RTT need be set at the integral multiple of radio frames according to the processing delay of equipment.As shown in Figure 4, the HARQ_RTT that sets each UL Subframe correspondence is 2 times of Frame duration; The corresponding respectively HARQ process ID of two ULSubframe that is numbered the Frame of odd number is 1,2; The corresponding respectively HARQ process ID of two UL Subframe that is numbered the Frame of even number is 3,4.
Suppose that the processing time-delay of equipment is respectively the processing delay Tenb=3ms of eNB, the processing delay Tue=2ms of UE, then the synchronous HARQ transmission time sequence of each UL Subframe correspondence of tdd frame structure as shown in Figure 2 is as shown in Figure 5.The corresponding downstream feedback of ascending HARQ transmission of carrying out at the UL of Frame N Subframe 2 can issue at the DL of Frame N+1 Subframe 1 the earliest, if transmission of data blocks is made mistakes, then Dui Ying re-transmission can be carried out minimum HARQ_RTT=10ms the earliest at the UL of Frame N+2 Subframe 2; In like manner, the downstream feedback that the ascending HARQ that carries out at the UL of Frame N Subframe 3 transmits issues as far back as the DL of Frame N+2 Subframe 0, if transmission of data blocks is made mistakes, then Dui Ying re-transmission can be carried out minimum HARQ_RTT=10ms the earliest at the UL of Frame N+2 Subframe 3; In like manner, the downstream feedback that the ascending HARQ that carries out at the UL of Frame N Subframe 4 transmits issues as far back as the DL of Frame N+2 Subframe 0, if transmission of data blocks is made mistakes, then Dui Ying re-transmission can be carried out minimum HARQ_RTT=10ms the earliest at the UL of Frame N+2 Subframe 4.
Transmission time sequence in the analysis chart 5, on the basis of considering the device processes time delay in order to guarantee the HARQ_RTT minimum of each ULSubframe correspondence: the ULGrant of UL Subframe 2 need send at the DL of Frame N+1 Subframe 1 among the Frame N+2; The UL Grant of UL Subframe3 need send at the DL of Frame N+2 Subframe 0 among the Frame N+2; The UL Grant of ULSubframe 4 need send at the DL of Frame N+2 Subframe 0 or 1 among the Frame N+2.
Be UL Subframe 3/4 follow-up 1st and 2 DUSP between at the UL Grant (USI=1/2) of UL Subframe 3/4 scheduling this moment; And be the 2nd and 3 the UL Subframe 2 between the DUSP at the UL Grant (USI=0) of UL Subframe 2 scheduling.The K value difference that each UL Grant scheduling is adopted contradicts with the rule of " dispatching UL Subframe between follow-up K and K+1 the DUSP at the UL of DL Subframe Grant " in the prior art.If in order to satisfy in the prior art " dispatching UL Subframe between follow-up K and K+1 the DUSP at the UL of DL Subframe Grant ", needing the HARQ_RTT of expansion Subframe 3/4 is 15ms.Promptly in Fig. 5, the UL Grant (USI=1) that the DL Subframe 0 of Frame N+2 sends dispatches the UL Subframe 3 of Frame N+3; The UL Subframe 4 of UL Grant (USI=2) the scheduling Frame N+3 that the DL Subframe 0 of Frame N+2 or 1 sends, the K value that K=2, and each UL Grant at this moment dispatches employing is identical.But this scheme causes the HARQ_RTT=15ms of UL Subframe 3/4, and the time interval between adjacent twice transmission increases the transmission performance that has reduced system.

Fig. 6 has provided the sequential relationship of synchronous HARQ and ascending resource scheduling, supposes that the minimum HARQ_RTT that satisfies the device processes delay requirement equals twice Frame length.As can be seen, as shown in Equation 1:
d＝HARQ_RTT-Ts-Tenb-Tue [1]
Wherein, Tenb is the processing time-delay of eNB equipment; Tue is the processing time-delay of UE equipment; Ts is the time span of a Subframe.DL Subframe in interval d sends at the UL Grant of transmitting uplink data next time, both can guarantee that eNB had finished the processing to last transmitting uplink data, interval d can guarantee that again UE can finish the processing to UL Grant before transmitting uplink data next time, so can be called between the maximum available area that issues UL Grant.Between definite maximum available area, after the d, can take following several method configuration distributing time interval and uplink subframe scheduling strategy in light of the circumstances,, below various concrete performances be described in detail to carry out the dynamic dispatching of ascending resource.

Ts+Tenb+Tue≥HARQ_RTT-Tframe [2]
Wherein, Tframe is the length of a Frame.
The situation that embodiment one corresponding coincidence subinterval equals 0, in this case, the time interval that issues of the pre-configured UL Grant of system is d between maximum available area, and pre-configured uplink subframe scheduling strategy, the implicit expression corresponding relation that is sub-frame of uplink index USI and the UL Subframe among the radio frames Frame that dispatches among the UL Grant is: at the UL Grant of UL Subframe P after being disposed by UE, always dispatching a follow-up nearest UL Subframe P, also is that system is pre-configured according to the corresponding relation between the subframe numbering of existing LTE technology USI and ULSubframe simultaneously.

A11, eNB are that UE divides the ascending resource that is coordinated in UL Subframe P among the Frame N;
ENB is that UE distributes ascending resource may be based on the first scheduling of resource of being carried out that passes of data block, also may be to retransmit the scheduling of resource of being carried out based on data block after transmission of data blocks is made mistakes; If data block retransmits, because adopt the synchronous HARQ technology, so the subframe numbering of the UL Subframe that dispatches when the subframe of the UL Subframe of this data block retransfer scheduling is numbered P with this data block of last time transmission is identical, the time interval of this transmission and this data block of last time transmission is the pre-configured HARQ_RTT of system;
A12, eNB determine the time interval that issues of UL Grant according to configuration, and selectedly issue DL Subframe available on the time interval;
ENB adopts timing mechanism, can safeguard transmission time sequence voluntarily, and eNB can determine the time interval that issues of UL Grant according to the transmission time sequence of configuration and maintenance voluntarily, and the time interval that issues of UL Grant is d between maximum available area in the present embodiment;
For example, eNB can determine that the absolute time that the UL Subframe P of this scheduling takies is 100ms according to the transmission time sequence of safeguarding voluntarily, if the HARQ_RTT=10ms of system configuration, Ts=1ms, Tenb=3ms, Tue=2ms, then can determine and issue time interval, be d=4ms between maximum available area, further can determine and issue time interval between absolute time the 94ms～97ms, eNB can obtain DL Subframe available between the 94ms～97ms after determining;
A13, eNB send UL Grant to UE on selected DL Subframe, to the indication of ascending resource assignment information, it is corresponding with the subframe numbering P of the UL Subframe P that distributes that the USI value is set.

Embodiment two
Among the embodiment two, suppose that the interval d of the UL Subframe P correspondence of adjacent Frame has coincidence in time, shown in formula [3]:
Ts+Tenb+Tue＜HARQ_RTT-Tframe [3]
Embodiment two is corresponding to overlap subintervals greater than 0 situation, in this case, because each radio frames all has two adjacent radio frames, so at the UL Subframe P in some specific radio frames, d is divided into three parts between the maximum available area that issues UL Grant of its correspondence, the two parts that comprise two ends overlap subinterval and middle non-coincidence subinterval, the coincidence subinterval that in order to express easily claims front end is the first coincidence subinterval, and the coincidence subinterval of rear end is the second coincidence subinterval.As shown in Figure 6, for d between the maximum available area of the UL Subframe P correspondence among the radio frames Frame N+3, be divided into three parts and comprise: non-available subinterval is positioned at the middle part of d; Between the maximum available area corresponding with UL Subframe P among the Frame N+2 between the d first overlaps the subinterval, is positioned at the front portion of d; Between the maximum available area corresponding with UL Subframe P among the Frame N+4 between the d second overlaps the subinterval, is positioned at the rear portion of d.In each overlaps subinterval, send at the UL Grant of UL Subframe P after being disposed by UE, both can dispatch follow-up nearest UL Subframe P, also can dispatch the UL Subframe P that closes on for follow-up time, if do not adopt this moment certain measure will cause the fuzzy of resource allocation.At this situation, the measure of taking among the embodiment two is that each overlaps a UL Subframe P transmission UL Grant at the less Frame of number of frames among the adjacent Frame in the subinterval.In this case, the time interval that issues of the pre-configured UL Grant of system is to remove among the d between maximum available area between the remaining area that is positioned at the first coincidence subinterval, comprises that promptly non-coincidence subinterval and second overlaps the subinterval.The pre-configured uplink subframe scheduling strategy of system, the implicit expression corresponding relation that is sub-frame of uplink index USI and the UL Subframe among the radio frames Frame that dispatches among the UL Grant is: at the ULGrant of UL Subframe P after being disposed by UE, always dispatching a follow-up nearest UL Subframe P, also is that system is pre-configured according to the corresponding relation between the subframe numbering of existing LTE technology USI and UL Subframe simultaneously.
Pre-configured according to system, the ascending resource scheduling of eNB and UL Grant process of transmitting comprise:
A21, eNB are that UE divides the ascending resource that is coordinated in UL Subframe P among the Frame N;
ENB is that UE distributes ascending resource may be based on the first scheduling of resource of being carried out that passes of data block, also may be to retransmit the scheduling of resource of being carried out based on data block after transmission of data blocks is made mistakes;

A23, eNB send UL Grant to UE on selected DL Subframe, the ascending resource assignment information is indicated, and it is corresponding with the subframe numbering P of the UL Subframe P that distributes that the USI value is set.
UE receives the processing method behind the UL Grant, comprising:
B21, UE handle this signaling after receiving the UL Grant of eNB transmission, obtain the ascending resource assignment information, are defined as the subframe numbering P of the UL Subframe of its distribution according to USI;
The upstream data UL Data that b22, UE preparation will send;
B23, UE send upstream data UL Data according to being configured on the indicated ascending resource of UL Grant among the follow-up nearest UL Subframe P to eNB.
Uplink scheduling method in the TDD system that the employing embodiment of the invention two provides, the implicit expression corresponding relation that issues sub-frame of uplink index USI and the UL Subframe among the radio frames Frame that dispatches among time interval and the UL Grant of the pre-configured UL Grant of system, because the interval d of the ULSubframe P correspondence of adjacent Frame has coincidence in time, so the configuration distributing time interval is to issue between the maximum available area of ULGrant d to remove first and overlap between the remaining area in subinterval, and configuration pin to the UL Grant of ULSubframe P after being disposed by UE, always dispatch a follow-up nearest ULSubframe P, adopt this method can guarantee that HARQ_RTT satisfies the minimum time of device processes time delay and remains unchanged, to guarantee the optimum transmission performance of system, realized dynamic dispatching simultaneously to resource.
Embodiment three
Embodiment three is also corresponding to overlap the subinterval greater than 0 situation, and at this situation, the measure of taking is that each only overlaps in subinterval the ULSubframe P transmission UL Grant at the Frame that number of frames is bigger among the adjacent Frame.In this case, the time interval that issues of the pre-configured UL Grant of system is to remove second between maximum available area among the d to overlap between the remaining area in subinterval, promptly comprises non-coincidence from the interval and first coincidence subinterval.The pre-configured uplink subframe scheduling strategy of system, the implicit expression corresponding relation that is sub-frame of uplink index USI and the UL Subframe among the radio frames Frame that dispatches among the UL Grant is: at the UL Grant of UL Subframe P after being disposed by UE, UE judges the subinterval that receives ULGrant, if receive in non-coincidence subinterval, then in a follow-up nearest ULSubframe P, send upstream data UL Data to eNB; If receive in the first coincidence subinterval, then sending upstream data UL Data according to being configured among a follow-up contiguous UL Subframe P to eNB, also is that system is pre-configured according to the corresponding relation between the subframe numbering of existing LTE technology USI and UL Subframe simultaneously.
