Description

A kind of method of scheduling of resource and subscriber equipment

Technical field

The present invention relates to communication technical field, particularly a kind of method of scheduling of resource and subscriber equipment.

Background technology

At existing Long Term Evolution (Long Term Evolution, hereinafter referred to as LTE) in communication system, subscriber equipment (User Equipment, hereinafter referred to as UE) Radio Resource that sends to the upstream data of network to use, depend on base station, as evolved node (evolved Node B, hereinafter referred to as eNodeB) distribute, the Radio Resource distributing to UE adopts the mode of signaling to inform to this UE by eNodeB, the data be buffered in logic channel group, according to resource indicated in signaling, are passed through obtained resource and are sent by this UE.ENodeB be UE distribute and scheduling resource before, eNodeB need determine dispatch to the size of the resource of UE, in order to reduce unnecessary waste Radio Resource as far as possible, eNodeB needs for UE distributes suitable resource, to reach the object making full use of Radio Resource.In order to reach this object, first needing UE by the data volume of its buffer memory, being reported to eNodeB by the mode of signaling, its data cached priority of eNodeB comprehensive assessment, the factors such as quantity, finally for one or many scheduling of resource initiated by subscriber equipment.

When eNodeB is that the ascending resource that UE distributes is enough large, when this resource can not be filled up by the data volume of UE, then after this resource can be loaded data by UE, remaining part is filled.This part does not have actual information amount, is only used to fill up used ascending resource.Use after filling, do not increase upstream data rate, the transmitting power of ascending resource and UE can be wasted, also may form interference to other UE.

In prior art, when eNodeB is UE Resources allocation, by reporting buffer status report (Buffer Status Report, hereinafter referred to as BSR) notify needed for eNodeB self resource value, the BSR reported is a discrete sheet, as shown in table 1 below, and span is 0 to 63, use 6bit to represent, wherein each value can indicate a data weight range.Data volume scope indicated by BSR index 2 is 10 to 12 bytes.

Table 1

Index	The data volume of the UE buffer memory of representative, unit is byte
		0	BS＝0
1	0＜BS＜＝10
		2	10＜BS＜＝12
...	...
		30	826＜BS＜＝967
31	967＜BS＜＝1132
		...	...
61	109439＜BS＜＝128125
		62	128125＜BS＜＝150000
63	BS＞150000

UE is after having reported BSR, and eNodeB can only know a scope of UE buffer data size, and carries out the uplink data scheduling of UE according to this scope.So can not dispatch very accurately.ENodeB cannot know the resource required for UE accurately, and therefore in order to can the data volume of UE buffer memory have been dispatched in time, then the upper limit that eNodeB can tend to the BSR reported according to UE is dispatched, thus causes filling.

Therefore, adopt this technical scheme to carry out the scheduling of resource of UE, waste the transmitting power of uplink transmission resource and UE.

Embodiment

For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not paying the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

It should be noted that, be described and elaboration in the following embodiment of the present invention using eNodeB as the example of base station, those of ordinary skill in the art can understand eNodeB not as the restriction of base station.

In embodiments of the present invention, sending multiple BSR to meet the mode of precision conditions by adopting, carrying out the accuracy of scheduling of resource to improve eNodeB for UE.In the present embodiment, can precision conditions be defined, determine the number of the BSR that UE reports with this.

In one embodiment, eNodeB is by RRC reconfiguration message or system broadcast message notice UE precision conditions, described precision conditions is for representing the levels of precision using described BSR to indicate the data cached value of described UE, described precision conditions comprises: the difference between the upper limit of the data volume represented by described BSR and the data cached value of described UE is less than first threshold, or the difference between the lower limit of data volume represented by described BSR and the data cached value of described UE is less than Second Threshold, or the difference between the higher limit of data volume represented by described BSR and lower limit is less than the 3rd threshold value.As, error amount is less than 100 bytes.Difference between the upper limit of the data volume represented by BSR that this error amount can report for UE and the data cached value of described UE, the difference between the lower limit of the data volume represented by BSR that also can report for UE and the data cached value of described UE.This precision conditions can be the precision conditions that all logic channel groups share, and also can be the precision conditions that different logic channel group configuration is different.The present embodiment defines the difference between the upper limit of the data volume represented by BSR that this error amount reports for UE and the data cached value of described UE

When UE reports BSR, judge whether a BSR value of this logic channel group meets precision conditions corresponding to this logic channel group.If met, then send a BSR to eNodeB; ENodeB is UE Resources allocation according to this BSR, completes scheduling of resource.The precision conditions sending the logic channel group of data as UE requires that error is less than 200 bytes, the data cached value of UE is 1000, then sending index is that the BSR of 31 is to eNodeB, data volume scope indicated by it is 967 < BS (the data cached value of Buffer Size) <=1132, error amount is 132, meets precision conditions.

If a BSR does not meet precision conditions, and if ascending resource can hold two BSR, then can send two BSR.It should be noted that, in one embodiment, the ascending resource of UE can hold multiple BSR, in another embodiment, if can not hold two BSR, then only sends a BSR.

If two BSR still can not meet precision conditions, then UE can send plural BSR, until meet precision conditions.

Be described with concrete example below: suppose that the buffer data size of UE is 1000 bytes, eNodeB permissible accuracy condition is that error is less than 100 bytes, if then UE only sends a BSR, then by searching BSR table, can to obtain corresponding index be 31, data volume scope is 967 < BS <=1132, error amount is 132, does not meet the area requirement of 100 bytes.

Then UE can report multiple BSR, the plurality of BSR can comprise the BSR that index is 30, data volume scope is 826 < BS <=967, and a BSR index is 9, data volume scope is 31 < BS <=36, according to these two BSR, can determine that the buffer data size of UE is 998 (967+31) < BS <=1003 (967+36) byte, error amount only has 3 bytes, improves the precision that eNodeB knows UE buffer data size.

Suppose have 10000 byte datas to need transmission, if then UE only sends a BSR, then index is 45, and data volume scope is 8787 < BS <=10287, and error amount is 287 bytes.

If resource allows, two BSR can be sent, then UE can send an index is the BSR of 44, data volume scope is 7505 < BS <=8787, be the BSR of 32 with an index, data volume scope is 1132 < BS <=1326, and the data volume of two BSR representatives is 9919 < BS <=10113 bytes.Error amount is 132 bytes;

If resource allows, three BSR can be sent, then UE can send an index is the BSR of 44, data volume scope is 7505 < BS <=8787, be the BSR of 31 with an index, data volume scope is 967 < BS <=1132, and an index is the BSR of 15, data volume scope is 78 < BS <=91, the data volume that these three BSR can represent is 9997 < BS <=10010 bytes, error amount is 10 bytes.

The method of the above-mentioned BSR of reporting substantially increases the precision that eNodeB knows UE buffer data size, and simultaneously because the extra expense reporting BSR itself to bring only has 4 bytes or 8 bytes more, the resource taken can be ignored more.

When reporting multiple BSR, UE reports BSR according to data cached logic channel group, if data buffer storage is in a logic channel group, then UE only needs to report Short BSR, if more than one logic channel group is cached with data, then UE needs to report Long BSR.Represented the scope of the data values indicated by this BSR by the index of BSR, the index as BSR is 30, and the scope of the data values indicated by it is 826 < BS <=967.

It should be noted that, if when UE utilizes multiple logic channel group to send data, then UE needs to send Long BSR.Namely the method is for logic channel group.So UE has multiple logic channel group to have data to need to send, when reporting multiple BSR, likely there will be a BSR is Long BSR, a BSR is the situation of Short BSR: the data volume as certain logic channel group uses a BSR value to meet precision conditions, another logic channel group needs use two BSR values to meet precision conditions, and now UE may send dissimilar BSR.When needs report multiple BSR, when can report Long BSR and Short BSR, also can all report Long BSR simultaneously.

Accordingly, above-mentioned eNodeB is defined as the resource of described UE distribution according to described BSR, comprising:

Described eNodeB is defined as the upper and lower bound of the resource value that UE distributes according to described 3rd BSR and at least one the 4th BSR described;

The difference of the lower limit of the data volume of the upper limit indicated by: the upper limit of the data volume indicated by described 3rd BSR and at least one the 4th BSR described of described resource of distributing for UE;

Concrete, for above-described embodiment, three BSR that eNodeB can report according to UE calculate needs the resource of distributing to UE to be 10001 bytes.

The present embodiment determines accuracy requirement by adopting eNodeB, UE can by sending the mode of multiple BSR, make eNodeB can in conjunction with multiple BSR, the more accurate resource value being defined as UE distribution, which thereby enhance the effect of the scheduling of resource of UE, save the transmitting power of ascending resource and UE.

In one embodiment, can also before execution step 202, this UE first determines that the data cached value of this UE is greater than the 4th threshold value, 4th threshold value can be arranged according to logic channel group, can be that different logic channel groups arranges the 4th different threshold values, also logic channel group that can be all arranges same 4th threshold value, above-mentioned 4th threshold value can be carried on eNodeB send reconfiguration message or system broadcast message in, described UE can by reception above-mentioned reconfiguration message or system broadcast message obtain the 4th threshold value.

UE, by arranging above-mentioned 4th threshold value, to make when the data volume of UE buffer memory is less, directly can upload BSR and carry out scheduling of resource, not need service precision condition to retrain.When the data cached value of UE is greater than the 4th threshold value, when resource requirement is larger, can determine to report multiple BSR, and be that constraint determines that BSR is to carry out scheduling of resource with precision conditions.

In the present embodiment, UE determines to indicate the data cached value of described UE and before meeting the BSR of described precision conditions, the buffer data size judging described UE is also needed whether to be greater than the 4th threshold value of the corresponding logic channel group arranged, if, then illustrate that UE needs to use more resource, then send according to the method in above-described embodiment the scheduling that BSR carries out user resources, method is similar to the above embodiments, repeats no more herein.

If the data volume of UE buffer memory is not more than this threshold value, then send a BSR, and the scope of data values indicated by this BSR comprises the buffer data size of described UE.After eNodeB receives this BSR, just can be defined as the resource value that UE distributes.

Be described with concrete example below: suppose that the buffer data size of UE is 900 bytes, 4th threshold value of data cached logic channel group is 1000 bytes, then UE can send an index is the BSR of 30, data volume scope is 826 < BS <=967, then eNodeB can be just 826 < BS <=967 for user carries out scheduling of resource in data volume scope.

ENodeB can notify UE the 4th threshold value, as 1000 bytes by RRC reconfiguration message or system broadcast message.4th threshold value can be the public threshold value of all logic channel groups, also can be the threshold value that different logic channel group configuration is different.

The present embodiment combines these the two kinds of modes of the 4th threshold value and the precision conditions arranged, whether the buffer data size of first decision logic channel group exceeds the 4th threshold value of setting, if exceed the 4th threshold value, then adopt the mode sending multiple BSR, and be constraint with precision conditions, determine that multiple BSR is effectively to carry out scheduling of resource.When the buffer data size of UE is less, directly carry out scheduling of resource, simplify scheduling of resource process; When taking resource and being more, guarantee the accuracy of scheduling of resource, thus effectively raise the effect of UE scheduling of resource.

In one embodiment, above-mentioned precision conditions can be carried on eNodeB send reconfiguration message or system broadcast message in, described UE can by reception above-mentioned reconfiguration message or system broadcast message obtain this precision conditions.

The present embodiment sends the mode of multiple BSR by adopting, and makes eNodeB can in conjunction with multiple BSR, and the more accurate resource value being defined as UE and distributing, which thereby enhances the effect of the scheduling of resource of UE, save the transmitting power of ascending resource and UE.

Further, in order to obtain relatively accurate BSR value, above-mentioned two kinds of computational methods can combine use, represent more accurate buffer data size to use less BSR quantity.An indication information can be increased, clearly use to make eNodeB the BSR reported to calculate the account form of the scope of the data cached value of UE.In a present embodiment, a reserved place in the sub-head of agreement can be used to determine to indicate the data cached value of described UE to indicate above-mentioned two kinds and meet the method for the BSR of described precision conditions.Or eNodeB also can configure to adopt which kind of account form, and now, UE uses above-mentioned reserved place to indicate with regard to not needing.

It should be noted that, the mode triggering UE transmission BSR in the above-described embodiments can be send announcement information by eNodeB to UE, to notify that UE accurately reports BSR, comprises the precision conditions that eNodeB is arranged in an announcement message, as error amount is less than 100.Or also can determine to adopt by UE oneself mode reporting multiple BSR, and carry indication information in the BSR reported, this UE of this indication information instruction eNodeB adopts the mode sending multiple BSR to carry out reporting of BSR.
