Description
Technical field
The invention belongs to mobile communication technology field, for fast dispatch, specifically a kind of suitable fast dispatch
SR collocation methods.
Background technology
In LTE230 systems, the UPpts positions on each subband are assigned to the position of SR requests, in this position
It is upper that 8 Preamble are produced by cyclic shift.In order to prevent the interference of adjacent cell, cell can divide in every 8 25ms frames
It is fitted on a uplink pilot time slot（UpPts）The transmission of SR is carried out, each cell is transmitted in which radio frames can be passed through
The mode of frame number mould 8 is calculated.So, will imply that 8 25ms frames can be respectively allocated to 8 cells and be adjusted
Degree.Each cell uses 1 frame in every 8 25ms frames, used as the SR resources of this cell.
One SR resource is to combine the common resource information for limiting by time and lead code Preamble, same
The different terminals of cell will distribute different SR resources, substantially be for they distribute different Preamble yards, these SR moneys
Source is by the UpPts of correspondence same number of frames, but corresponding Preamble yards is different, therefore essence is for they distribute different
Preamble yards.Due to 8 Preamble, therefore a cell can be produced at every 8 as described previously by cyclic shift
There to be 8 SR resources in 25ms frames.So add up 8 cells, in 8 25ms frames, 64 SR resources will be had,
And it is interior in 1s, equivalent a total of 320 SR resources are used for all 8 cells.
The fast dispatch of LTE230 systems, by sending subband number（The frequency location that UE will work）, and by acquiescence
Realize the SR positions of UE.Under this mode, the SR positions of UE acquiescences turn into a key technology.Existing LTE230 is by specifying
This cell last SR resource location is used as fast dispatch position.
This cell last SR resource location can be clearly specified to have the following disadvantages at present：1st, due to needing to wireless
Terminal resource is sufficiently utilized, and does not allow the terminal in idle condition to take a certain resource for a long time, so terminal is one
In the case of fixed will in the middle of acquiescence working frequency and fast dispatch frequency frequency hopping back and forth；2nd, the response speed of terminal is not fast enough, from
DRX wakes up to and can finally start SR request uploads, and maximum possible continues 38 radio frames.In a word, clearly refer in the prior art
The method of last SR resource location of this cell causes the time that fast dispatch is averagely accessed calmly, and efficiency is too low.
The content of the invention
To solve the above-mentioned problems in the prior art, the present invention is intended to provide a kind of SR configurations of suitable fast dispatch
Method, selects original every 8 frame a frame and distributes to 8 orthogonal code SR schemes of an independent cell and be changed into dividing equally each frame
Dispensing one orthogonal code of each cell, to reduce the time that fast dispatch is averagely accessed, improves access efficiency.
To achieve the above object, the technical scheme for being used is as follows for the present invention：
A kind of SR collocation methods of suitable fast dispatch, the method includes：
1. the resource in each SR cycle is carried out into Unified number or mapping numbering；
Resource in described each SR cycle, i.e., 8 25ms frames amount to 64 SR；
2. each CELL ID obtains SR resources according to the mode of CELL_ID moulds 8, to ensure that every frame each cell has one
SR resources；
3. the frame mould 20 of each cell is equal at 7 or 8, is set to fast dispatch SR resources.
Used as optimization, the method also includes：To each cell, each frequency distributes different SR code words, so that cell space-time
Ensure complete orthogonal with frequency.
The present invention as a result of above-mentioned structure, its compared with prior art, acquired technological progress is：
（1）The present invention reduces the time that fast dispatch is averagely accessed by code division mode, improves access efficiency；
（2）Cell space-time of the present invention is entirely orthogonal with frequency, reduces peak-to-average force ratio.
The present invention is applied to fast dispatch.
Specific embodiment
Illustrated below in conjunction with to the preferred embodiments of the present invention.It should be appreciated that preferred embodiment described herein
It is merely to illustrate and explain the present invention, is not intended to limit the present invention.
A kind of SR collocation methods of suitable fast dispatch of embodiment
A kind of SR collocation methods of suitable fast dispatch, including：
1. by the resource in each SR cycle, i.e., 8 25ms frames amount to 64 SR resources, carry out Unified number or mapping is compiled
Number；
2. each CELL ID obtains SR resources according to the mode of CELL_ID moulds 8, to ensure that every frame has one in each cell
Individual SR resources；
3. it is equal at 1 because DRX is always positioned at frame mould 20, therefore the frame mould 20 of each cell is equal at 7 or 8, is set to fast
Velocity modulation degree SR resources.
Being launched simultaneously using same code word in view of same cell side frequency can bring the situation of peak-to-average force ratio increase, to every
The different SR code words of individual cell each frequency distribution, so that cell space-time ensures complete orthogonal, such as frequency of cell 1 with frequency
1 uses code word 1, frequency 2 to use code word 2；The frequency 1 of cell 2 uses code word 2, frequency 2 to use code word 1, equal to ensure reduction peak
Than.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
Although being described in detail to the present invention with reference to the foregoing embodiments, for a person skilled in the art, it still may be used
Modified with to the technical scheme described in foregoing embodiments, or equivalent is carried out to which part technical characteristic.
All any modification, equivalent substitution and improvements within the spirit and principles in the present invention, made etc., should be included in power of the present invention
Within the scope of profit is claimed.
