Description
Technical field
The present invention relates to the communications field, buffer status report (Buffer Status Report, referred to as BSR) processing method, device and terminal under a kind of carrier aggregation.
Background technology
Carrier aggregation technology is supplied to UE(subscriber equipment) higher data bandwidth, this technology is at a Transmission Time Interval (Transmission Time Interval, referred to as TTI) in be supplied to many (the maximum 5) transmission block (TransportBlocks of UE, referred to as TB) transmission, and not using carrier aggregation technology, UE can only have a TB to transmit.Multiple TB transmission means can carry multiple buffer status report BSR cell, the up buffer status of what BSR cell carried is UE side, i.e. up outgoing data size, is built by medium education (Media Access Control, referred to as MAC) module.Agreement specifies that information that BSR cell carries must be the buffer status after whole TB group bag.
Under carrier aggregation technology, UE has needed the Medium Access Control (MAC) Protocol Data Unit (Protocol Data Unit, referred to as PDU) on multiple TB to build within a TTI cycle.If carry out independent BSR process to each TB, then can consume comparatively multiple instruction, especially the scene that BSR cell is cancelled (conventional or cycle BSR condition trigger but current uplink scheduling can complete the transmission of UE total data time, BSR can be cancelled send) in, MAC PDU in each TB may be caused to carry out secondary structure, namely first time MAC PDU group bag just finds that BSR cell is cancelled after completing, thus causes group bag rule to change, and this just needs again to build MAC PDU; And in first time MAC PDU group packet procedures, just precisely determine that group bag rule is more bothersome, because accurately judge that the BSR cell of routine/cycle triggering is positioned at more efficient on which TB (namely optimum group bag efficiency), whether BSR cell finally can be cancelled, these all need all back end traveling through the current all logical channel queue of UE, also need the size traveling through each TB simultaneously, such process is equal to carries out a MAC PDU group packet procedures, and resource consumption is large.
Conventional way is generally reserved BSR resource, just judges whether to cancel when organizing last back end of last logic channel, thus uses resource reserved for BSR cell to group MAC PDU.Under carrier aggregation scene, because there is multiple TB, if therefore current group of MAC PDU be not last TB, then badly determine whether TB below can organize all data thus cancel the BSR resource reservation on current TB.If current reservations BSR resource, after TB meets cancellation condition during group MAC PDU, then current TB and follow-up TB needs again to organize MAC PDU.
If simply the structure of routine/cycle BSR cell is put on last TB, if TB so above can place BSR cell and not place, just fill PADDING byte, UE group MAC PDU bag efficiency can be made again low, and base station side also can be made to obtain UE buffer status not in time, because support that the agreement of carrier aggregation technology regulation can carry BSR cell (a routine/cycle BSR many PADDING BSR) on multiple TB.
In addition, if because the BSR that signal difference of eating dishes without rice or wine causes UE to report is not received by base station, so base station may think that UE is current does not need uplink scheduling, and base station can be caused so no longer initiatively to distribute ascending resource to UE; And UE stresses to pass that BSR timer is the shortest also wants 320 milliseconds, after such UE may can only wait for this timer expiry, UE triggers SR(dispatch request again) rule application ascending resource.If now carry out uplink service, if file transfer protocol (FTP) (File Transfer Protocol, referred to as FTP), IP-based voice transfer (VoIP Voice over IP, referred to as VOIP) etc., so long break period can cause very large negative effect.
Therefore, in the related under carrier aggregation technology, there is resource consumption greatly in the BSR process of UE, process complexity is high, and efficiency is low causes the problem affecting base station assigns resource.

Embodiment
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Provide buffer status report BSR processing method under a kind of carrier aggregation in the present embodiment, Fig. 1 is the flow chart of buffer status report BSR processing method under the carrier aggregation according to the embodiment of the present invention, and as shown in Figure 1, this flow process comprises the steps:
Step S102, sorts from big to small to the transmission block TB in delivery time interval T TI;
Step S104, the TB finally organizing bag when definition base sequence packages to current cache data is the carrying position of the BSR in carrying TTI;
Step S106, by the carrying position carry BSR determined, to package transmission to TB included in TTI.
Pass through above-mentioned steps, when there is multiple TB in TTI, the TB finally organizing bag when definition base sequence packages to current cache data is the carrying position of the BSR in carrying TTI, according to the carrying position determined, TB is packaged transmission data, to solve in correlation technique under carrier aggregation technology, it is large to there is resource consumption in the BSR process of UE, process complexity is high, efficiency is low causes the problem affecting base station assigns resource, and then reach the complexity reducing under multiple TB scene and build BSR, avoid the effect of the wasting of resources.
More preferably, can sort from big to small to the TB in TTI in physical layer, namely just sort according to size when it detects up TB resource, like this than on upper strata (such as, media access control MAC layer) sequence consume instruction to lack, be conducive to the saving to signaling.
Multiple processing mode can be adopted when determining the carrying position of BSR in TTI according to the size of each TB in the size of current cache data and TTI, such as, first can sort from big to small to the TB detected in physical layer according to above-mentioned process; Determine to meet current cache data group bag, and the TB of last group bag is the carrying position of BSR.It should be noted that, this BSR can be placed on any one in all TB before this last TB, certain estimated bias may be there is owing to packaging to current cache data, therefore, in order to ensure the group bag of current cache data, usually coming the last TB(i.e. TB of last group bag) upper this BSR of carrying.
After determining the carrying position of BSR by sequence, in order to determine the success rate of BSR further, can by the carrying position carry BSR that determining, before TB included in TTI is packaged and sent, judge that the retransmission probability of the TB of last group bag is whether in predetermined threshold range; When judged result is for being, the TB maintaining last group bag is the carrying position of BSR; And/or, when judged result is no, the TB of retransmission probability in predetermined threshold range in the TB before the TB in the end organizing bag is updated to the carrying position of BSR.Owing to being the threshold decision based on carrying out retransmission probability after first time sequence, therefore, too many instruction consumes is not needed to the traversal of TB position.
It should be noted that, due to the TB of multiple retransmission probability in threshold range may be there is before last TB after the first sorting, therefore, determine that in the TB before the TB corresponding to carrying position, the TB of retransmission probability in threshold range is that the carrying position of BSR can also adopt multiple processing mode, such as, specifically determine which TB can also adopt following processing mode, after TB is sorted from big to small, judge that the retransmission probability of the TB in the end organized before the TB of bag is whether in predetermined threshold range successively, by the TB of retransmission probability in predetermined threshold range with finally organize the TB wrapped and carry out position and exchange, determine that the TB of last group bag after changing over is the carrying position of BSR.In other words, after the TB packaged to current cache data sorts from big to small, from the TB of last group bag, according to order from small to large, judge that the retransmission probability of the TB in the end organized before the TB of bag is whether in predetermined threshold range successively; By the TB of the retransmission probability that determines of first time in predetermined threshold range with finally organize the TB wrapped and carry out position and exchange; The carrying position that the TB wrapped is updated to BSR is finally organized after changing over.
In addition, can only try one's best to a certain extent due to process before and improve BSR successful probability, fully can not avoid the failure of BSR transmission, and bust this process of feedback still exists compared with long delay.To this, the TB of the present embodiment to carrying BSR has carried out marking process, namely after the TB finally organizing bag when definition base sequence packages to current cache data is the carrying position of BSR in carrying TTI, for the TB carrying BSR adds accessory ID, wherein, accessory ID is for informing that the hybrid automatic repeat-request HARQ of TB is sent result feedback to media access control MAC module by physical layer.When MAC module receives the feedback of repeat requests failure, in next TTI, directly process is transmitted to BSR.

Based on the problems referred to above, provide the process of a kind of link layer MAC PDU control cell BSR under carrier aggregation technology in the present embodiment.Below with Long Term Evolution (Long Term Evolution-Advanced, referred to as LTE-A) be described for example, in the method, UE can reduce group bag complexity, it is more suitable to be placed on by BSR cell, on the TB block had higher success rate, and can determine whether BSR reports in time and successfully apply for carry out repeating transmission BSR or SR; Meanwhile, when abundant resource, on more TB, carry BSR cell as far as possible.Below the method is simply set forth:
UE, when receiving multiple TB, carries out first round sequence to these TB, and principle is according to principle from big to small, if such reason is that follow-up TB only will be simple PADDING BSR and report if the large TB come above can complete the group bag of all data;
The up cache size current according to UE, estimates BSR cell and is carried on which TB, if all TB resources have all been not enough to the transmission of the current upstream data of UE, then BSR cell is placed on last TB; Now need to consider the retransmission probability of UE in each TB respective base station, if the retransmission probability estimating UE on base station corresponding to the TB that places BSR cell is high, namely up transmission is second-rate, then carry out second and take turns sequence.Second principle of taking turns sequence is, from the TB of the carrying BSR determined after last round of sequence, inverse iteration, exchanges the TB satisfied condition of retransmission probability and the current TB estimating carrying BSR cell.As far as possible the object of epicycle sequence improves BSR cell to send successful probability, in order to avoid the uplink scheduling that base station can not receive and causes postpones.The position estimating BSR cell does not need the back end traveling through all logic channels, just uses the up cache size of current maintenance, and first round TB sequence determines resource distribution, and therefore this step does not expend how many instructions.
Just improve the successful probability of BSR because last round of as far as possible, BSR cell can not be avoided completely to report failure, therefore on the TB reporting BSR cell, auxiliary sign is increased, this mark need not be sent to base station, only need to inform UE side physical layer, physical layer is after the TB having this to indicate sends, to the HARQ(hybrid automatic repeat-request of final (comprising HARQ to retransmit) be fed back) send result feedback to MAC module, if the final feedback of HARQ is that ACK(just replys), then MAC module does not carry out any process; If final feedback is NACK(negative acknowledge), then mean that HARQ retransmits and still fail to send successfully.So, at next TTI, if UE obtains ascending resource, then MAC module resends BSR cell and upgrades corresponding operation; If there is no ascending resource, then judge whether up BSR cell is that conventional BSR triggers further, if it is UE triggers SR mechanism application ascending resource immediately, and such way without prejudice to agreement, because conventional BSR trigger condition before can trigger SR mechanism.
Each factor of comprehensive above-mentioned structure BSR, below the rule of the correspondence of each factor above-mentioned is described: regular 1:BSR cell be carried at finally complete group bag that TB on, namely in this TTI, the TB of last participation group bag carries BSR, if still have residue TB resource after group bag completes, these TB only do PADDING process.Rule 2: in the scene of multiple TB block, if TB resource is enough, as far as possible use TB less, if i.e. 5 TB, only have 2 just can complete group bag, after 3 do not participate in group bag can raise the efficiency, therefore size sequence is carried out to TB, end group packet procedures on large TB of namely trying one's best above.Rule 3: as far as possible little at retransmission probability, namely send on the good TB of condition and carry BSR, because BSR is very important for scheduling, priority is high, so need ensure as possible to send success rate; But regular 2 Sum fanction 3 potentially conflictings, therefore need to consider; Therefore after the sequence of rule 2, if find originally to determine the TB carrying BSR, retransmission probability is excessive, just by it and sequence comparing successively before him, finds retransmission probability suitable, then TB position is exchanged, the reason changed over is, must meet rule 1, and the TB that namely last group is wrapped carries BSR, because the exact value of BSR, need occur in group wrapped after.Note: real group bag (comprising the structure of BSR) occurs in after 3 rules complete above, namely determines final TB order and just starts to organize bag.Rule 4: after above-mentioned BSR position is finally determined, sending the time again retransmitting BSR unsuccessfully, carrying mark to this TB, requiring that PHY reports HARQ result to accelerate TB, with the re-transmission BSR when next send opportunity as early as possible.
By above-described embodiment, complexity MAC PDU building BSR cell under multiple TB uplink scheduling scene can be reduced, avoid sending MAC PDU in time and causing ascending resource to be wasted; The method provides BSR to send successful probability simultaneously, and can need the situation of ascending resource by timely signals base UE when sending unsuccessfully, the problem of the ascending resource assignment latency that base station so just can be avoided to cause because of failing promptly and accurately to obtain UE information.
Below in conjunction with accompanying drawing, the preferred embodiment for the present invention is described.
Fig. 7 is the flow chart of BSR signaling process under multiple up TB resource scene according to the preferred embodiment of the present invention, and as shown in Figure 7, this flow process comprises the steps:
Step S700, current TTI has multiple up TB scheduling of resource, and namely current TTI cycle UE has multiple uplink authorization (TB block);
Step S702, carries out first round sequence, according to the size of TB block, arranges from big to small, and namely maximum TB is positioned at foremost, and minimum being positioned at is last.This minor sort occurs in physical layer, when its inspection just arranges according to size to during up TB resource, fewer than the instruction consumed in the sequence of MAC module like this;
Step S704, judges whether to trigger routine or cycle BSR; If had, be for further processing, otherwise terminate this process;
Step S706, according to the current up data cached size of UE and the total size of TB, estimates BSR cell and will be structured on which TB, mark this TB as BSR cell carrier block;
Step S708, the retransmission probability of UE on the TB respective cell that judgement is labeled, if retransmission probability is greater than threshold value, namely may exists and send failed risk, then carry out next step; No person skips to step S712;
Step S710, based on the result of first round sequence, from determining the TB of carrying BSR after last round of sequence, from small to large, judge that whether the retransmission probability of current TB respective cell is up to standard successively, namely lower than threshold values, if up to standard, end loop, by this TB and the TB transposition being labeled as carrying BSR cell before, and current TB is labeled as BSR cell carrier block;
Step S712, the TB of final carrying BSR cell adds mark, for informing that the HARQ of this TB of physical layer feedback sends final result;
Step S714, judging that the HARQ of physical layer feedback sends whether final result is NACK, is carry out next step; Otherwise terminate this process;
Step S716, arranges BSR retransmission flag;
Step S718, judges whether next TTI has uplink authorization dispatch, if had, to enter step S720, otherwise enter step S722;
Step S720, if next TTI has up TB resource, then repeats the building process of BSR cell;
Step S722, determines whether that conventional BSR triggers, if it is carries out SR processing procedure;
Step S724, is left intact.
