The absolute value of the difference between the available scheduling request resources number of subframe is less than given threshold.
It should be noted that terminal to the process of base station requests ascending resource as shown in figure 4, i.e. terminal is according to certain week
Pass through PUCCH (Physical Uplink Control Channel, physical uplink control channel) on phase and subframe position
In control message transmission SR, i.e., when terminal have send data demand when, SR is just put 1 accordingly, when there is no resource request
SR is set to zero, SR to be only responsible for telling whether base station has resource requirement, and specifically needs signaling of how many resource then after to hand over
Mutually tell base station.After base station receives SR, UL grant (uplink scheduling authorization) are issued, first configure small part resource and used to terminal,
The enough terminals of this part resource upload BSR (buffer state report, caching report), and terminal sends to base station afterwards
BSR, i.e., tell the data volume size to be transmitted of base station oneself again, and base station is received after the BSR of terminal to report, according in the terminal
The comprehensive analysis such as the SRS (souding reference signal, detection reference signal) and base station existing resource of report are determined
It is no to give terminal distribution resource, if condition meets just allocates resources to terminal, if condition is unsatisfactory for just not allocating resources to terminal, when
After enough resources are distributed to terminal in base station, terminal just can send upstream data in these resources.
In order to solve the problems, such as that the resource that base station is randomly assigned in sub-frame of uplink in the prior art causes distribution to fail, this hair
Base station authorizes according to setting configuration rule to the resource in sub-frame of uplink in bright embodiment, with ensureing two sub-frame of uplink
Resource be uniformly distributed to terminal, the difference between remaining available resource in latter two sub-frame of uplink being configured
Meet certain span, such as, the difference of two resources of sub-frame of uplink is zero, or be 1 or minus 1 etc., that is,
The absolute value of difference is less than given threshold, and given threshold can be zero, 1 with value.Specifically, the base station is determined on described first
Between the number of the available scheduling request resources of the number of the available scheduling request resources of row subframe and second sub-frame of uplink
Initial difference；
If the absolute value of the initial difference is less than the given threshold, the configuration rule that sets is as by the first up son
The available scheduling request resources of frame are allocated toIndividual uplink scheduling request, by the available scheduling request resources of the second sub-frame of uplink
It is allocated to residueIndividual uplink scheduling request, wherein N are the up tune that each terminal that base station receives sends in same time slot
Degree request number.
If the absolute value of the initial difference is not less than the given threshold, the configuration rule that sets is as up by first
The available scheduling request resources of subframe are allocated to the uplink scheduling requestBy the second up son
The available scheduling request resources of frame are allocated to the uplink scheduling requestWherein, N is connect for base station
The uplink scheduling request number that each terminal received sends in same time slot, K1 is the remaining available tune of first sub-frame of uplink
Degree request resource number, K2 is the remaining available scheduling request resources number of second sub-frame of uplink,To round up,To round downwards, λ is configuration coefficients.
It should be noted that can be able to be PUSCH (Physical Uplink Shared with scheduling request resources
Channel, Physical Uplink Shared Channel) or RB (, Resource Block, Resource Block), a uplink scheduling for terminal please
Asking can correspond to configuration one PUSCH or multiple, or, a uplink scheduling request for terminal can correspond to configuration one
RB or multiple.So λ may value be 1,1/2 etc., the difference between K2 and K1 represents the second sub-frame of uplink and first up
The difference of the available scheduling request resources between subframe, may be for just, it is also possible to be negative, it is assumed that it is 4, explanation that K1 subtracts K2 differences
The remaining available scheduling request resources of first sub-frame of uplink are 4 more than the second sub-frame of uplink, it is assumed that the first sub-frame of uplink residue 19
Individual RB, the second sub-frame of uplink 15 RB of residue, in addition, λ is 10 equal to 1/2, N, then this time just distribute the first sub-frame of uplinkIndividual resource, that is, 7 uplink scheduling requests configuration resource of the first sub-frame of uplink is distributed, in addition,
Distribute the second sub-frame of uplinkIndividual resource, that is, distribute the second sub-frame of uplink 3 uplink schedulings please
Configuration resource is sought, after this sub-distribution, the second sub-frame of uplink 12 RB of residue, the first sub-frame of uplink also 12 RB of residue, therefore
The difference of the remaining available scheduling request resources between the second sub-frame of uplink and the first sub-frame of uplink is with regard to vanishing.
Specifically, base station receives eventually at the T0 moment by the PUCCH of descending sub frame 0 (Physical Downlink Control Channel)
The SR requests and BSR for sending are held, determines that current time user is terminal 1 according to SR requests.Because being carried out with descending sub frame 0 up
It is sub-frame of uplink 4 and sub-frame of uplink 7 to authorize associated, so base station is by a DCI0 dispatching uplinks subframe 7, indicates up son
Frame 7 is authorized, wherein, UL_INDEX in DCI0 is 1, and then base station is by the sequence number 7 of sub-frame of uplink and 50 PUSCH of distribution
Correspondence notifies that to the terminal 50 PUSCH that then terminal passes through on sub-frame of uplink 7 at the up moment send upstream data.
Then, base station is at T1 moment, the SR requests sent by the receiving terminal on the PUCCH of special subframe 1, according to SR
Request determines that current time number of users is 3 terminals (terminal 2, terminal 3 and terminal 4), because carrying out up awarding with special subframe 1
It is sub-frame of uplink 7 and sub-frame of uplink 8 that power is associated, so base station is by a DCI1 dispatching uplinks subframe 7 and sub-frame of uplink 8,
Sub-frame of uplink 7 and sub-frame of uplink 8 is indicated to authorize, wherein, the UL_INDEX in DCI1 is 3.Because 50 in sub-frame of uplink 7
PUSCH is configured at the T0 descending moment, according to setting rule, base station by the sequence number 7 of sub-frame of uplink and distribution 50
Individual PUSCH (assuming that total number of channels 100 of sub-frame of uplink) correspondence is notified to the terminal 2, by the sequence number 8 of sub-frame of uplink and distribution
50 PUSCH correspondences notify to the terminal 3, the sequence number 8 of sub-frame of uplink and 50 PUSCH of distribution correspondences are notified to should
Terminal 4, then, terminal 2, terminal 3 and terminal 4 send upward signal on the channel of respective distribution, after being configured so that, on
Resource in row subframe 7 and sub-frame of uplink 8 just can in a balanced way distribute to each terminal, latter two sub-frame of uplink being configured it
Between the difference of resource be zero, both ensure that the utilization rate of interface-free resources, also improve the success rate that base station is terminal distribution resource.
Certainly, it is assumed that at the T2 moment, it is 1 that base station receives dispatch request number, and counterpart terminal 5, base station passes through one
DCI0 dispatching uplinks subframe 4, indicates sub-frame of uplink 4 to authorize, wherein, UL_INDEX in DCI0 is 2, and then base station is by up son
The sequence number 4 of frame and 50 PUSCH of distribution correspond to notice to the terminal, and then terminal passes through sub-frame of uplink 4 at the up moment
On 50 PUSCH send upstream data, then, at the T3 moment, base station receives dispatch request number for 2, the He of counterpart terminal 6
Terminal 7, base station just can be by the sequence number 8 of sub-frame of uplink and 50 PUSCH of distribution correspondence notices to the terminal 6, will be up
The sequence number 7 of subframe and 50 PUSCH correspondences of distribution are notified to the terminal 7.
After the resource for being configured with sub-frame of uplink according to the method described above, base station updates the available scheduling of the first sub-frame of uplink
The available scheduling request resources number of request resource number and second sub-frame of uplink, that is to say, that base station record is configured it
The resource of current time remaining sub-frame of uplink afterwards, to carry out considering as reference value during uplink authorization next time.
Further, for each terminal, generate the terminal the corresponding scheduling request resources of uplink scheduling request and
The corresponding relation of the sequence number of the sub-frame of uplink where the corresponding scheduling request resources；The base station passes through the first descending sub frame
PDCCH (Physical Downlink Control Channel) corresponding relation is sent to each terminal so that the terminal utilize the tune
Degree request resource sends upstream data.
That is, base station will carry out the sequence number of the sub-frame of uplink of uplink authorization and the PUSCH of distribution is notified to terminal, than
The sequence number 8 of sub-frame of uplink and 50 PUSCH this corresponding relations of distribution are such as sent to terminal 6 by PDCCH, so end
End 6 can just send upstream data on the PUSCH of 50 on sub-frame of uplink 8.
Further, if being directed to a terminal, included in corresponding relation corresponding with the uplink scheduling request of the terminal
The scheduling request resources of different sub-frame of uplink, then the base station by a PDCCH of the first descending sub frame by the correspondence
Relation is sent to the terminal.Such as, 30 on 20 PUSCH and sub-frame of uplink 8 in base station on sub-frame of uplink 7
PUSCH configurations give terminal 6, then base station just only needs to be notified to terminal 6 with a PDCCH, thus, it is apparent that can just avoid
Using two PDCCH notify that the resource of PDCCH can be saved to terminal 6 respectively.
