The second embodiment of uplink shared resources Pooled resources distribution method of the present invention is introduced with reference to Fig. 4.

Step 401, the subframe structure according to TDD proportionings 0, count authorize the moment to treat first sub-frame of uplink of scheduling respectively Remaining bandwidth resource ucFirstRbNum and second sub-frame of uplink remaining bandwidth resource ucSecondRbNum；

Here, the remaining bandwidth resource refers to remove PUCCH resource, PRACH resources, Msg3 scheduling, retransmission process, single-shot PUSCH bandwidth resources outside the bandwidth of the occupancy such as UCI.

Step 402, according to ucFirstRbNum and ucSecondRbNum, obtain virtual resource shared pool VirtualResourcePoolRbNum；

VirtualResourcePoolRbNum is obtained specifically, being calculated according to formula (1),

VirtualResourcePoolRbNum=(ucFirstRbNum+ucSecondRbNum) * Percentfactor (1)

Wherein, percentage specific factor Percentfactor=α (1 one β)+β, β are the value determined by system testing, and β's takes It is [α, 1] to be worth scope, and α is definite value, α=max (ucFirstRbNum, ucSecondRbNum)/(ucFirstRbNum+ UcSecondRbNum), Percentfactor spans [α, 1]；

For example in a radio frame, 9U and 2U, 2U and 3U, 4U and 7U, 7U and 8U separately constitute virtual shared resource pond, During wherein 9U and 2U combinations, 9U is first sub-frame of uplink, and 2U is second sub-frame of uplink, and other combinations are similar.Implementation One：The 5D of moment current radio frames is being authorized to the 9U of current radio frames and 2U mandates, the current radio frames of next radio frames 6S authorized to the 2U and 3U of next radio frames, the 0D of current radio frames is authorized to current radio frames 4U and 7U, current wireless The 1S of frame is authorized to the 7U and 8U of current radio frames；Or, implementation two：Given authorizing the 5D/6S of moment current radio frames Authorized to the 9U of current radio frames and the 2U of next radio frames, the 6S of current radio frames is awarded to the 2U and 3U of next radio frames Power, the 0D/1S of current radio frames are authorized to the 4U and 7U of current radio frames, the 1S of current radio frames is to current radio frames 7U and 8U Authorize；

Using virtual shared resource pond as one foundation of UE resource allocations, can avoid upstream bandwidth distribution it is excessive cause it is excellent The low UE distribution of first level can also avoid the too small up band for causing single UE or many UE to distribute of upstream bandwidth distribution less than resource The waste of wide resource, more rationally distributes up-link resource for UE, improves cell uplink flow system flow.

Step 403, according to UE waiting dispatch two sub-frame of uplink dispatch situation, determine resource allocation pre-scheduling mark money Source distribution pre-scheduling mark AllocationFlag；

If specifically, retransfer scheduling, UCI scheduling etc. is not present in first sub-frame of uplink in UE, in second up son When frame has retransfer scheduling, UCI scheduling etc., the AllocationFlag is entered as 1, represents resource in advance on first Row subframe is distributed；

If UE has retransfer scheduling, UCI scheduling etc. in first sub-frame of uplink, re-transmission is not deposited in second sub-frame of uplink When scheduling, UCI scheduling etc., the AllocationFlag is entered as 2, represents resource in advance in second sub-frame of uplink point Match somebody with somebody；

If UE is in first sub-frame of uplink and second sub-frame of uplink UE not retransfer scheduling, UCI scheduling etc., and two The new data of individual sub-frame of uplink hybrid automatic repeat-request (Hybrid Automatic Repeat Request, HARQ) process When indicating that (New Data indication, NDI) is identical, the AllocationFlag is entered as 3, represents that resource is advance Distributed simultaneously with second sub-frame of uplink public resource bitmap at first and NDI is identical；

If UE is in first sub-frame of uplink and second sub-frame of uplink not retransfer scheduling, UCI scheduling etc., and two When the NDI of sub-frame of uplink HARQ processes is differed, the AllocationFlag is entered as 4, represents resource in advance first Individual and second sub-frame of uplink is distributed simultaneously and NDI is differed.Two DCI0 can be now issued by same descending sub frame For sub-frame of uplink mandate, or DCI0 issued for sub-frame of uplink mandate by different descending sub frames respectively；

Because PRACH resources and Msg3 scheduling can only a sub-frame of uplink, therefore without resource allocation pre-scheduling wherein Mark；

The effect of the AllocationFlag is similar but different with UL index effect, and UL index values are Determined after final resource allocation success, and AllocationFlag carries out resource point for mark UE in advance in which sub-frame of uplink The subframe index matched somebody with somebody, can determine that UL index guide direction to be final, for example, AllocationFlag=1 UE resources point With the UL index=10 after success；UL index=01 after AllocationFlag=2 UE resource allocations success； UL index after AllocationFlag=3 UE resource allocations success are generally 10,01 or 11；AllocationFlag= ULindex is 01 or 10 after 4 UE resource allocations success, can so reduce the time of system resource allocation, lifting user's money Source allocative efficiency.

Step 404, when UE queues to be dispatched not be sky, and UE (Buffer Status Reporting, BSR) BSR_{Equivalent G BR}(the BSR of ＞ 0_{Equivalent G BR}It is not 0 logic channel BSR sums for the BSR with GBR and PBR in logic channel group) when, root Identified according to the virtual shared resource pond of determination and resource allocation pre-scheduling, carry out first time resource allocation and obtain final for the first time point The RB numbers Rb matched somebody with somebody_{AllocationMaxNmu_First}；
