Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to ascending resource distribution, status report sending method and device.
Background technology
The uplink scheduling process of existing mobile communication system mainly comprises two aspect contents, and the one, buffer status report BSR (Buffer Status Report) mechanism, the 2nd, ascending resource assigning process.
Defined the format and content that mobile terminal UE (User Equipment) sends to the BSR report of base station among the standard 3GPP TS 36.321V8.3.0 of existing 3GPP LTE R8.Wherein, have QoS radio bearer RB (Radio Bearer) composition radio bearer group RBG (RBGroup) close or equal priority and carry out the BSR report, its short-and-medium BSR only reports the buffer data size BS with limit priority RBG (Buffer Size), its form as shown in Figure 1, and long BSR can report the BS of four kinds of RBG, its form as shown in Figure 2, wherein LCG ID is the identification number of logic channel group, Buffer Size is the buffer data size of each RBG, and Oct represents a byte.
For ascending resource assigning process (may also be referred to as the upstream rate control procedure), also defined the ascending resource assigning process in the current LTE standard among 3GPP TS 36.321V8.3.0 and the 3GPP TS 36.300V8.6.0, the resource allocation process of UE side is mainly finished by Token Bucket Policing, as shown in Figure 3:
The corresponding token bucket of each RB, wherein BS is this RB corresponding cache data volume, priority bit speed PBR (Prioritized Bit Rate) is the actual speed of injecting in each cycle of corresponding token bucket, it is the token number of putting into token bucket in each cycle, the basic rate that PBR can be understood as RB requires or guarantees substantially rate requirement, this value is the fixed numbers relevant with RB priority, and Bj is a token number in the token bucket, and R is the data volume of current actual transmission of transmission cycle.
The UE side is undertaken by Token Bucket Policing that ascending resource distributes and uplink rate control method is as follows:
Step 1: when the upstream data transmission cycle arrives, upgrade Bj according to PBR.
Step 2: press RB priority order from high in the end and be the RB Resources allocation of all Bj＞0, and upgrade Bj (Bj can be for negative, can avoid frequently cutting apart and assembling of packet like this) according to resource allocation result;
Step 3: if still have ascending resource residue, be each RB Resources allocation (regardless of size of Bj value) then, finish or do not remain ascending resource (Bj no longer upgrades in this step) up to the data cached transmission of this RB according to priority order from high to low.
Carry out the ascending resource distribution first time in the above-mentioned steps 2, distribute ascending resource by RB according to the BS of its corresponding Bj, correspondence and the minimum value of current residual ascending resource, to reach the purpose of the PBR rate requirement that preferentially satisfies the high RB of priority to Bj＞0.
Carry out the ascending resource distribution second time in the above-mentioned steps 3, the residue ascending resource after the first time, ascending resource distributed is distributed to each RB, to reach the purpose that makes full use of ascending resource.
The base station should be for the ideal situation that each UE carries out the ascending resource distribution according to the BSR that each UE reports, make when UE adopts above-mentioned Token Bucket Policing to distribute ascending resource to give its each RB, the ascending resource that the ascending resource that UE obtains is enough finished in the above-mentioned steps 1 distributes, and promptly satisfies the PBR rate requirement of its each RB correspondence.But because ascending resource is limited, each UE may be given by the reasonable distribution ascending resource in the base station, after the ascending resource that the UE that promptly may have obtains can satisfy the PBR rate requirement of its each RB correspondence, ascending resource also has residue, and the ascending resource that the UE that have this moment obtains also can't satisfy the PBR rate requirement of its each RB correspondence.For example, when carrying out ascending resource, a UE divides timing, satisfy the PBR rate requirement of its each RB correspondence, and will remain after ascending resource distributes to its each RB, when the buffer data size of the RBG of this UE is still very big, UE with this buffer data size reporting base station after, the base station still can distribute more ascending resource to give this UE according to this buffer data size, because ascending resource is limited, the PBR rate requirement that causes base station assigns to be not enough to satisfy other each RB of UE for the ascending resource of other UE causes the base station to distribute ascending resource unreasonable for each UE.
UE carries out ascending resource by above-mentioned Token Bucket Policing to its each RB and distributes, ascending resource distributes carrying out for the first time, after satisfying the PBR rate requirement of each RB correspondence, as also having the ascending resource residue, then carrying out for the second time, ascending resource distributes, promptly according to priority from high to low order will remain ascending resource and distribute to each RB, suppose that some RB have obtained the residue ascending resource, but no longer upgrade the Bj of this RB correspondence this moment, if in the next one transmission cycle, when the ascending resource that UE obtains is not enough to satisfy the PBR rate requirement of all RB correspondences, but UE still may give this RB with the priority allocation ascending resource, therefore, cause after satisfying the PBR rate requirement of this RB correspondence, this RB has obtained more ascending resource simultaneously, also has the RB that does not satisfy the PBR rate requirement, causes the ascending resource unreasonable distribution.

Embodiment three:
The embodiment of the invention three provides a kind of status report sending method, as shown in Figure 8, comprising:
Step S801, portable terminal are determined in the inherent ascending resource for the second time distribution of current upstream data transmission cycle and are obtained first radio bearer of the ascending resource quantity of ascending resource or acquisition greater than setting threshold.
Step S802, to each radio bearer group, calculate all the other each radio bearer corresponding cache data volumes except that first radio bearer and value.
Step S803, transmission should and be worth to the base station; Perhaps satisfy send when condition is set should and value to the base station.
The status report sending method that the embodiment of the invention three is provided is described in detail below.
In the embodiment of the invention three, the UE side is distributed to each RB that it comprises by Token Bucket Policing with the ascending resource of its acquisition, comprising:
Step 1: when the upstream data transmission cycle arrives, upgrade token number Bj according to priority bit speed PBR.
Step 2: according to RB priority order from high to low is the RB Resources allocation of all Bj＞0, and upgrades Bj (Bj can be for negative, can avoid frequently cutting apart and assembling of packet like this) according to resource allocation result.
Step 3: if still have ascending resource residue, be each RB Resources allocation (regardless of size of Bj value) then, finish or do not remain ascending resource up to the data cached transmission of this RB according to priority order from high to low.
In the above-mentioned steps 1, each RB is added the PBR quantity that it is corresponding on the former Bj of its correspondence, the result is as upgrading its corresponding Bj of back.
Carry out the ascending resource distribution first time in the above-mentioned steps 2, for current pending RB, UE determines to distribute to the ascending resource of this RB according to the Bj and the residue ascending resource quantity of this RB corresponding cache data volume BS, this RB correspondence.After distributing ascending resource to give this RB, upgrade the Bj of this RB correspondence accordingly, be specially: deduct the ascending resource quantity of distributing to this RB in former Bj, the result is as the Bj after upgrading; The corresponding BS that also upgrades this RB correspondence is specially: deduct the ascending resource quantity of distributing to this RB in former BS, the result is as the BS after upgrading; Also upgrade residue ascending resource quantity accordingly, be specially: deduct the ascending resource quantity of giving this RB in former surplus resources quantity, the result is as the residue ascending resource quantity after upgrading.After finishing this step, as there not being the situation of avoiding packet to cut apart and assemble, Bj equals zero, and as existing, then Bj is less than zero.
After above-mentioned steps 3 is completing steps 2, if still have the step that ascending resource when residue carry out.Carry out the ascending resource distribution second time in the step 3, promptly distribute ascending resource to give several RB once more, for the RB that obtains ascending resource once more, the corresponding BS that upgrades this RB correspondence, be specially, deduct the ascending resource quantity of distributing to this RB in former BS, the result is as the BS after upgrading; Also upgrade residue ascending resource quantity accordingly, be specially: deduct the ascending resource quantity of giving this RB in former surplus resources quantity, the result is as the residue ascending resource quantity after upgrading.But for the Bj of each RB correspondence, during execution in step 3, the Bj of each RB correspondence all smaller or equal to zero, even then RB obtains ascending resource again, does not upgrade Bj yet.
Therefore, among the above-mentioned steps S801, first radio bearer is: the ascending resource of the RB of acquisition ascending resource or acquisition is greater than the RB of setting threshold in the above-mentioned steps 3.
When calculating each RBG corresponding cache data volume among the step S802, do not consider the first radio bearer corresponding cache data volume, promptly only calculate all the other each RB except that first radio bearer buffer data size and value.
Above-mentioned steps S803 is specifically as follows:
Each upstream data sends cycle and all sends this and value to the base station; Perhaps
Satisfy send when condition is set should and value to the base station.For example, when this RBG correspondence should and value send during greater than setting threshold should and value to the base station; Perhaps send periodically this RBG should and value to the base station, this cycle is the above-mentioned upstream data integral multiple in transmission cycle.
