Below in conjunction with Fig. 4, the second embodiment of uplink shared resources Pooled resources distribution method of the present invention is introduced.
Here, described remaining bandwidth resource refers to the PUSCH bandwidth resources the bandwidth taking except PUCCH resource, PRACH resource, Msg3 scheduling, retransmission process, single-shot UCI etc.
Concrete, calculate VirtualResourcePoolRbNum according to formula (1),
VirtualResourcePoolRbNum=(ucFirstRbNum+ucSecondRbNum)*Percentfactor(1)
Wherein, percentage factor Percentfactor=α (1 one β)+β, β is the value definite by system testing, the span of β is [α, 1], and α is definite value, α=max (ucFirstRbNum, ucSecondRbNum)/(ucFirstRbNum+ucSecondRbNum), Percentfactor span [α, 1];
For example, in a radio frames, 9U and 2U, 2U and 3U, 4U and 7U, 7U and 8U form respectively virtual shared resource pond, and when wherein 9U and 2U combine, 9U is first sub-frame of uplink, and 2U is second sub-frame of uplink, and other composite class seemingly.Implementation method one: the 5D that authorizes moment current wireless frame to the 9U of current wireless frame and the 2U of next radio frames authorize, the 6S of current wireless frame to 2U and the 3U of next radio frames authorize, the 0D of current wireless frame to current wireless frame 4U and 7U authorize, the 1S of current wireless frame authorizes to 7U and the 8U of current wireless frame; Or, implementation method two: the 5D/6S that authorizes moment current wireless frame to the 9U of current wireless frame and the 2U of next radio frames authorize, the 6S of current wireless frame to 2U and the 3U of next radio frames authorize, the 0D/1S of current wireless frame to 4U and the 7U of current wireless frame authorize, the 1S of current wireless frame authorizes to current wireless frame 7U and 8U;
Distribute a foundation using virtual shared resource pond as UE resource, can avoid upstream bandwidth to distribute excessively causes the UE that priority is low to distribute less than resource, also can avoid upstream bandwidth to distribute the waste of the too small uplink bandwidth resource that causes single UE or many UE distribution, more rationally, for UE distributes up-link resource, improve cell uplink flow system flow.
Concrete, if UE does not exist retransfer scheduling, UCI scheduling etc. at first sub-frame of uplink, in the time that second sub-frame of uplink exists retransfer scheduling, UCI scheduling etc., be 1 by described AllocationFlag assignment, represent that resource is in advance in first sub-frame of uplink distribution;

If UE does not all have retransfer scheduling, UCI scheduling etc. at first sub-frame of uplink and second sub-frame of uplink UE, and two sub-frame of uplink mixed automatic retransfers request (Hybrid Automatic Repeat Request, HARQ) new data of process indication (New Data indication, NDI) when identical, be 3 by described AllocationFlag assignment, represent that resource is distributed with second sub-frame of uplink public resource bitmap at first in advance and NDI is identical simultaneously;
If UE does not all have retransfer scheduling, UCI scheduling etc. at first sub-frame of uplink and second sub-frame of uplink, and when the NDI of two sub-frame of uplink HARQ processes is not identical, be 4 by described AllocationFlag assignment, represent that resource is in advance at first with second sub-frame of uplink distributes and NDI is not identical simultaneously.Now can issue two DCI0 by same descending sub frame is sub-frame of uplink mandate, or to issue respectively DCI0 by different descending sub frames be sub-frame of uplink mandate;
Due to PRACH resource and a Msg3 scheduling sub-frame of uplink therein, therefore distribute pre-scheduling mark without resource;
The effect of the effect of described AllocationFlag and UL index is similar, but different, UL index value is to determine after final resource is allocated successfully, and AllocationFlag is the subframe index that identifies in advance UE and which sub-frame of uplink to carry out resource distribution at, can be that the final UL index of determining guides direction, for example, the UL index=10 of the UE resource of AllocationFlag=1 after being allocated successfully; UL index=01 after the UE resource of AllocationFlag=2 is allocated successfully; UL index after the UE resource of AllocationFlag=3 is allocated successfully is generally 10,01 or 11; It is 01 or 10 that the UE resource of AllocationFlag=4 is allocated successfully rear ULindex, can reduce like this time of system resource allocation, promotes user resources allocative efficiency.
