Description
The application be to the applying date be that on 03 04th, 2009, application number are 200910078851.7, the application name is called the dividing an application of patent application of " ascending resource distributes, status report sending method and device ".
Technical field
The present invention relates to wireless communication technology field, relate in particular to status report sending method and portable terminal.
Background technology
The uplink scheduling process of existing mobile communication system mainly comprises two aspects, and the one, buffer status report BSR(Buffer Status Report) mechanism, the 2nd, the 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, radio bearer RB(Radio Bearer with the close or equal priority of QoS) form radio bearer group RBG(RBGroup) carry out the BSR report, its short-and-medium BSR only reports the Size of the buffer data size BS(Buffer with limit priority RBG), 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 buffer data size corresponding to this RB, 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 the basic guarantee rate requirement, this value is the fixed numbers relevant with RB priority, and Bj is 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 for all Bj〉0 RB Resources allocation, and upgrade Bj(Bj according to resource allocation result can be for negative, can avoid so frequently cutting apart and assembling of packet);
Step 3: if still have ascending resource residue, be each RB Resources allocation (regardless of size of Bj value) according to priority order from high to low then, until this RB data cached is sent or do not remain ascending resource (Bj no longer upgrades in this step).
Carry out first time ascending resource in the above-mentioned steps 2 and distribute, by to Bj 0 RB distributes ascending resource according to its corresponding Bj, corresponding BS 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.
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 takes full advantage 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, so that UE is when adopting above-mentioned Token Bucket Policing to distribute ascending resource to its each RB, the ascending resource that the ascending resource that UE obtains is enough finished in the above-mentioned steps 1 distributes, and namely satisfies PBR rate requirement corresponding to its each RB.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 namely may have obtains can satisfy PBR rate requirement corresponding to its each RB, ascending resource also has residue, and the ascending resource that the UE that have this moment obtains also can't satisfy PBR rate requirement corresponding to its each RB.For example, when carrying out ascending resource, a UE divides timing, satisfy PBR rate requirement corresponding to its each RB, and after will remaining ascending resource and distributing to its each RB, when the buffer data size of the RBG of this UE is still very large, UE with this buffer data size reporting base station after, the base station still can distribute more ascending resource to this UE according to this buffer data size, because ascending resource is limited, cause base station assigns to be not enough to satisfy the PBR rate requirement of other each RB of UE to the ascending resource of other UE, cause the base station to distribute ascending resource unreasonable to 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 PBR rate requirement corresponding to each RB, as also having the ascending resource residue, then carrying out for the second time, ascending resource distributes, namely 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 Bj corresponding to this RB this moment, if within the next one transmission cycle, when the ascending resource that UE obtains is not enough to satisfy PBR rate requirement corresponding to all RB, but UE still may give this RB with the priority allocation ascending resource, therefore, cause after satisfying PBR rate requirement corresponding to this RB, 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.

Data in more above-mentioned table 1 and the table 2 are as seen: adopt existing uplink resource allocating method, after current period distributes for the second time, the RB1 and token number corresponding to RB2 that obtain ascending resource in distributing for the second time do not upgrade, so RB1 and token number corresponding to RB2 are updated to respectively 150 and 150 before distributing for the first time in next cycle, and then after RB1 and RB2 obtain respectively the ascending resource of 150 bytes and 100 bytes in distributing for the first time in next cycle, the residue ascending resource is zero, namely after satisfying PBR rate requirement corresponding to RB1, distribute to again its more ascending resource, and the ascending resource that RB3 obtains does not also satisfy its corresponding PBR rate requirement; And the method and apparatus that adopts above-described embodiment one and embodiment two to provide, after current period distributes for the second time, the RB1 and token number corresponding to RB2 that obtain ascending resource in distributing for the second time are updated to respectively-170 and-50, so RB1 and token number corresponding to RB2 are updated to respectively-20 and 100 before distributing for the first time in next cycle, and then, next cycle distribute for the first time in regardless of mixing capable resource to RB1, distribute the ascending resource of 100 bytes to RB2, the ascending resource that therefore can also distribute 100 bytes has satisfied PBR rate requirement corresponding to RB3 to RB3.Therefore, the uplink resource allocating method and the device that adopt the embodiment of the invention one and embodiment two to provide are so that the more rational distribution ascending resource of portable terminal is given its each radio bearer.
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 for the second time ascending resource distribution of current upstream data transmission cycle and are obtained the ascending resource quantity of ascending resource or acquisition greater than the first radio bearer of setting threshold.
Step S802, to each radio bearer group, calculate buffer data size corresponding to all the other each radio bearers except the 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 below is described in detail the status report sending method that the embodiment of the invention three provides.
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: be all Bj according to RB priority order from high to low〉0 RB Resources allocation, and upgrade Bj(Bj according to resource allocation result can be for negative, can avoid so frequently cutting apart and assembling of packet).
Step 3: if still have ascending resource residue, be each RB Resources allocation (regardless of size of Bj value) according to priority order from high to low then, until this RB data cached is sent or do not remain ascending resource.
In the above-mentioned steps 1, each RB is added the PBR quantity that it is corresponding at the former Bj of its correspondence, the result is as its corresponding Bj after upgrading.
Carry out first time ascending resource in the above-mentioned steps 2 and distribute, for current pending RB, Bj and residue ascending resource quantity that UE is corresponding according to buffer data size BS corresponding to this RB, this RB determine to distribute to the ascending resource of this RB.After distributing ascending resource to this RB, upgrade accordingly Bj corresponding to this RB, be specially: deduct the ascending resource quantity of distributing to this RB in former Bj, the result is as the Bj after upgrading; Accordingly also upgrade BS corresponding to this RB, 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 accordingly residue ascending resource quantity, 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 the step of carrying out when still having the ascending resource residue.Carry out the ascending resource distribution second time in the step 3, namely again distribute ascending resource to several RB, for the RB that again obtains ascending resource, corresponding BS corresponding to this RB that upgrade, 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 accordingly residue ascending resource quantity, 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 Bj corresponding to each RB, during execution in step 3, Bj corresponding to each RB all less than or equal to zero, even then RB obtains again ascending resource, do not upgrade Bj yet.
Therefore, among the above-mentioned steps S801, the 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 buffer data size corresponding to each RBG among the step S802, do not consider the buffer data size that the first radio bearer is corresponding, namely only calculate all the other each RB except the first radio bearer buffer data size and value.
Above-mentioned steps S803 is specifically as follows:
Each upstream data sends cycle and 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 corresponding 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.
Preferably, this RBG should and value can send to the transmission of MAC Control Element MAC Controlelement field corresponding with RBG among the medium access control layer protocol data cell MAC PDU of base station by portable terminal.The form of MAC PDU as shown in Figure 9.
Wherein, the business datum of each radio bearer is filled in media access control layer service data unit MAC SDU(MAC Service Data Unit) field, each MAC SDU field has a sub-heading sub-header corresponding with it in MAC heading MAC header field, wherein, " R " field contents is reserved bit, " E " field represents extended field, whether at MAC header more multiword section definition is arranged with expression; " L " field is indicated the length of corresponding MAC SDU or MAC control element, and the length of " L " is by " F " field identification; " LCID " field represents the Logic Channel Identifier of MAC SDU field or MACControl element field or padding Related fields.
Among other embodiment, in the above-mentioned steps 2, when being for the first time the first radio bearer distribution ascending resource, can carrying out ascending resource with PBR quantity corresponding to this RB according to the ascending resource quantity that this RB in the previous upstream data transmission cycle obtains and distribute in the second time, ascending resource distributed.For example, the ascending resource quantity that obtains in the second time, ascending resource distributed as this RB in the previous upstream data transmission cycle is during less than PBR corresponding to this RB, and the ascending resource quantity of distributing to this RB sends the difference of this RB ascending resource quantity of acquisition in the second time, ascending resource distributed in the cycle for PBR quantity corresponding to this RB and previous upstream data; The ascending resource quantity that obtains in the second time, ascending resource distributed as this RB in the previous upstream data transmission cycle is during greater than PBR corresponding to this RB, and then this ascending resource of not reallocating is to this RB.
Based on same inventive concept, according to the status report sending method that the above embodiment of the present invention three provides, correspondingly, the embodiment of the invention four provides a kind of portable terminal, and its structural representation specifically comprises as shown in figure 10:
Determining unit 1001 is used for determining the inherent for the second time ascending resource distribution of current upstream data transmission cycle and obtains the ascending resource quantity of ascending resource or acquisition greater than the first radio bearer of setting threshold;
Computing unit 1002 is used for each radio bearer group, calculate buffer data size corresponding to all the other each radio bearers except the first radio bearer and value;
Transmitting element 1003 is used for sending and should and be worth to the base station; Perhaps when satisfy send when condition is set should and value to the base station.
Preferably, should and value send to the transmission of MAC Control element field corresponding with this radio bearer group among the MAC PDU of base station by portable terminal.
The method and the device that adopt embodiment three and embodiment four to provide, above-mentioned the first radio bearer has obtained ascending resource after obtaining to satisfy the ascending resource of its PBR rate requirement again, represent that this UE has obtained to satisfy the outer more ascending resource of PBR rate requirement corresponding to its each radio bearer, when this situation occurring, with comparing to the base station with value of the buffer data size that sends all radio bearers that form this radio bearer group, it is less with value that the method sends, therefore, accordingly, the base station according to receive should and value to distribute to the ascending resource of this UE less, and then the ascending resource that reduces can be distributed to other UE, when avoiding occurring satisfying the more ascending resources of UE acquisition of PBR rate requirement corresponding to each RB, the situation that also has the UE that does not satisfy PBR rate requirement corresponding to each RB reaches the more rational distribution ascending resource in base station to the purpose of each UE.
Embodiment five:
The embodiment of the invention five also provides a kind of status report sending method, as shown in figure 11, comprising:
After step S1101, current upstream data sent and carry out ascending resource in the cycle and distribute, portable terminal was determined the smaller value of token number in token bucket corresponding to the radio bearer buffer data size corresponding with it;
Step S1102, to each radio bearer group, calculate this smaller value corresponding to each radio bearer of comprising and value;
Step S1103, transmission should and be worth to the base station; Perhaps when satisfy send when condition is set should and value to the base station.
The below is described in detail the status report sending method that the embodiment of the invention five provides.
In the embodiment of the invention five, 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: be all Bj according to RB priority order from high to low〉0 RB Resources allocation, and upgrade Bj(Bj according to resource allocation result can be for negative, can avoid so frequently cutting apart and assembling of packet).
Step 3: if still have ascending resource residue, be each RB Resources allocation (regardless of size of Bj value) according to priority order from high to low then, until this RB data cached is sent or do not remain ascending resource.
In the above-mentioned steps 1, each RB is added the PBR quantity that it is corresponding at the former Bj of its correspondence, the result is as its corresponding Bj after upgrading.
Carry out first time ascending resource in the above-mentioned steps 2 and distribute, for current pending RB, Bj and residue ascending resource quantity that UE is corresponding according to buffer data size BS corresponding to this RB, this RB determine to distribute to the ascending resource of this RB.After distributing ascending resource to this RB, upgrade accordingly Bj corresponding to this RB, be specially: deduct the ascending resource quantity of distributing to this RB in former Bj, the result is as the Bj after upgrading; Accordingly also upgrade BS corresponding to this RB, 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 accordingly residue ascending resource quantity, 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 the step of carrying out when still having the ascending resource residue.Carry out the ascending resource distribution second time in the step 3, namely again distribute ascending resource to several RB, for the RB that again obtains ascending resource, corresponding BS corresponding to this RB that upgrade, 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 accordingly residue ascending resource quantity, 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 Bj corresponding to each RB, during execution in step 3, Bj corresponding to each RB all less than or equal to zero, even then RB obtains again ascending resource, do not upgrade Bj yet.
Therefore, among the above-mentioned steps S1101, after carrying out ascending resource distribute within the current upstream data transmission cycle, the token number in token bucket corresponding to radio bearer is UE and finishes ascending resource and distribute token number after upgrading.This step is specifically as follows: obtain token number corresponding to each RB and buffer data size corresponding to each RB, for each RB, compare the size of its corresponding token number and its corresponding buffer data size, and choose minimum value wherein.
Above-mentioned steps S1102 is specifically as follows: to each RBG, calculate the smaller value determined among above-mentioned steps S1101 corresponding to each RB of comprising and value.
Above-mentioned steps S1103 is specifically as follows:
Each upstream data sends cycle and 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 corresponding 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 integral multiple in above-mentioned transmission cycle.
Preferably, this RBG should and value can send to the transmission of MAC Control Element MAC Controlelement field corresponding with RBG among the medium access control layer protocol data cell MAC PDU of base station by portable terminal.The form of MAC PDU as shown in Figure 9.
Wherein, the business datum of each radio bearer is filled in media access control layer service data unit MAC SDU(MAC Service Data Unit) field, each MAC SDU field has a sub-heading sub-header corresponding with it in MAC heading MAC header field, wherein, " R " field contents is reserved bit, " E " field represents extended field, whether at MAC header more multiword section definition is arranged with expression; " L " field is indicated the length of corresponding MAC SDU or MAC control element, and the length of " L " is by " F " field identification; " LCID " field represents the Logic Channel Identifier of MAC SDU field or MACControl element field or padding Related fields.
Based on same inventive concept, according to the status report sending method that the above embodiment of the present invention five provides, correspondingly, the embodiment of the invention six also provides a kind of portable terminal, and its structural representation specifically comprises as shown in figure 12:
Determining unit 1201 after being used for carrying out in the current up transmission cycle ascending resource and distributing, is determined the smaller value of token number in token bucket corresponding to the radio bearer buffer data size corresponding with it;
Transmitting element 1203 is used for sending and should and be worth to the base station; Perhaps when satisfy send when condition is set should and value to the base station.
Preferably, should and value send to the transmission of MAC Control element field corresponding with this radio bearer group among the MAC PDU of base station by portable terminal.
The method and the device that adopt embodiment five and embodiment six to provide, during status report, when the token number in token bucket corresponding to radio bearer during less than its corresponding buffer data size, distribute the ascending resource of this token number quantity can satisfy its corresponding PBR rate requirement to this radio bearer, and when the token number in its corresponding token bucket during greater than its corresponding buffer data size, distribute the ascending resource of this buffer data size quantity can send the whole data cached of this radio bearer to this radio bearer, if actual allocated is given the ascending resource of the ascending resource of this radio bearer greater than above-mentioned distribution, represent that then this radio bearer has obtained more residue ascending resource, when this situation occurring, with comparing to the base station with value of the buffer data size that sends all radio bearers that form this radio bearer group, it is less with value that the method sends, therefore, accordingly, the base station according to receive should and value to distribute to the ascending resource of this UE less, and then the ascending resource that reduces can be distributed to other UE, when avoiding occurring satisfying the more ascending resources of UE acquisition of PBR rate requirement corresponding to each RB, the situation that also has the UE that does not satisfy PBR rate requirement corresponding to each RB reaches the more rational distribution ascending resource in base station to the purpose of each UE.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
