With reference to preferred embodiment and embodiment, the present invention is described in detail.
The experience of the present invention is related to wireless communication field, and in particular to the band resource of LTE system is effectively utilized.Design a kind of base
In the bandwidth reduction launching technique and device of LTE standard, realize that LTE nonstandard bandwidths compress under existing LTE system standard,
In the case where ensureing the reliable communication of LTE system, wireless network spectrum efficient is utilized.
The preferred embodiments of the present invention propose a kind of bandwidth reduction transmitting based on LTE standard and method of reseptance and device.Exist
Under LTE standard, handled by the transmitting to LTE channels, realize reliable communication of the system under compression bandwidth.Wherein,
According to nonstandard bandwidth wireless network resource, select suitable LTE standard system bandwidth matching.It is upper and lower further according to LTE
The scheduling of row control channel and Traffic Channel and resource impact feature, using PCI screening modules and physical channel Dispatching adjustment module
Ensure uplink and downlink channel in the mapping minimum of frequency band or falling into outside nonstandard bandwidth for zero limit；Strengthen module pair using transmission power
Physical channel power strengthens, and improves transmission performance；Finally by RRU wave filters, the time domain with nonstandard bandwidth match is obtained
Signal is launched.Receiving terminal factually shows lossless or low damage according to the LTE system bandwidth logarithm of matching and received.Above-mentioned invented party
Method and device realize bandwidth reduction transmitting of the LTE system under nonstandard bandwidth resource, efficiently make use of wireless network resource.
The above method and device include：
The available wireless network bands of LTE are distributed to for LTE nonstandard bandwidths.The wireless network bands distributed are not equal to LTE
Standard bandwidth 1.4,3,5,10,15 or 20M.Here the wireless network bands distributed can be one big section of frequency band, by LTE
The frequency band between remainder or LTE system and other different networks after system bandwidth division.
LTE system is in order to make full use of above-mentioned wireless network bands, i.e. nonstandard bandwidth BWnonstandard, according to BWnonstandard
It is determined that from matching LTE standard system bandwidth BWchosed。BWchosedSelection principle for choose and BWnonstandardDifference
Value is more than 0, and the minimum BW of differencestandard.Here, BWstandard={ 1.4,3,5,10,15,20 } M.
Physical Cell Identifier (Physical Cell Indicator, referred to as PCI) is screened.LTE PCI has 504, is used for
Different LTE cells are distinguished, meanwhile, it can also influence scrambling and the mapping position of physical channel.Under compression bandwidth, to PCI
Screening is carried out to refer to：On the premise of the number for ensureing PCI meets networking requirement, PCI is traveled through, by screening physical control format
Indicate that channel (Physical Control Format Indication Channel, referred to as PCFICH) and physics HARQ indicate letter
Road (Physical HARQ Indication Channel, referred to as PHICH) channel resource mapping resource unit (Resource
Element, referred to as RE) without falling into or few fall into compression frequency band BWcompressed(i.e. BWchosedAnd BWnonstandardHand over
Frequency band beyond collection) within PCI carry out networking, so as to ensure PCFICH and PHICH performance.
Physical channel Dispatching adjustment includes LTE uplink and downlink physical channels.Specifically,
For up, the Dispatching adjustment method of use includes：In PUCCH scheduling, the offset to resource distribution is configured,
So that PUCCH starting RB positions fall in BWchosedIt is interior, so as to realize the bandwidth reduction of uplink communication.
It is Physical Uplink Control Channel (Physical Uplink first in the frequency band left and right sides that the characteristics of resource impact of up channel, which is,
Control Channel, referred to as PUCCH) channel, followed by Physical Random Access Channel (Physical Radom Access
Channel, referred to as PRACH) and Physical Uplink Shared Channel (Physical Uplink Shared Channel, referred to as PUSCH).
The resource impact original position of PUCCH channels will directly affect other up channels.So, as long as ensureing PUCCH tune
Degree is in BWchosedInterior, then other up channels naturally also just fall in BWnonstandardIt is interior.Here, it is therefore apparent that by this
Scheduling strategy uplink channel transmission is performance undamaged.
1st, for descending, the Dispatching adjustment method of use includes：
PDSCH scheduling of resource is adjusted：In BWchosedInterior is that unit carries out PDSCH scheduling with RB (Recourse Block).
, can only be in BW in order to ensure PDSCH transmission performancechosedIt is interior that it is scheduled.Under the physics of downlink traffic channel
Row shared channel (Physical Downlink Shared Channel, referred to as PDSCH) is scheduled by unit of RB.
2nd, PDSCH transmission mode adjustment：For the UE under wave beam forming (Beam Forming, referred to as BF) pattern,
As long as dispatching RB positions in compression BWnonstandardIt is interior；When BF patterns and non-BF patterns UE (User Equipment) are common
During subframe scheduling, the UE of BF patterns preferentially takes compression BWnonstandardLeft and right sides frequency band, rather than the user of BF patterns adjust
Spend RB positions more remote better far from left and right frequency band side.
Defined in LTE a variety of transmission modes (Transmission Mode, referred to as TM).The reference signal used from demodulation
Type difference can be divided into BF patterns and non-BF patterns.BF patterns correspondence TM7~10, using UE demodulation reference signals.
And TM1~6 are demodulated using cell reference signals.So, when the UE subframe schedulings altogether of BF patterns and non-BF patterns,
The UE of BF patterns is dispatched in BWnonstandardLeft and right band position, to should UE UE reference signals also in dispatch frequency range
Interior, so channel estimation does not influence, bandwidth reduction does not influence on demodulation performance；And be demodulated using cell reference channel
Non- BF patterns, because cell reference signals are launched in BWchosed, compress frequency band BWcompressedIn reference signal receive
Influence, in terms of channel estimation results, BW are arrivedchosedThe cell reference signals channel estimation value of the left and right sides is not very accurate (pressed
Contracting bandwidth contributions) demodulation can be influenceed.But, as dispatch frequency range is away from BWchosedThe left and right sides, compression bandwidth is to channel estimation
Influence can be less and less.So, the non-BF user demodulated using cell reference channel is dispatched in dispatch frequency range away from BWchosed
On the RB of the left and right sides, it can be ensured that the demodulation performance of the certain customers.
Channel power strengthens.Due to bandwidth reduction so that LTE system is according to BWchosedThe power compression of transmitting is in BWnonstandard
It is upper to be launched.So, can be by BW on the premise of ensureing that transmission power is no more than antenna emission maximumcompressedOn
Power is effectively utilized in BWnonstandardOn, i.e., power enhancing is carried out to data in effective bandwidth.
Here including up and down power strengthens, and also has different Enhancement Methods for up-downgoing, specifically,
For up, power is concentrated on into BWnonstandardIt is allocated.If performance can ensure, it is not necessary to which power strengthens,
Can not also do strengthens, and so also corresponds to economize on electricity.
For descending, power is concentrated on into BWnonstandardIt is allocated.Downlink physical down control channel (Physical Downlink
Control Channel, referred to as PDCCH) channel indicate in descending preceding control format (Control Format Indication,
Referred to as CFI) individual OFDM symbol frequency band on interweave break up mapping.So, the channel can not avoid it from falling into completely
BWcompressedIn.In order to ensure PDCCH performance, need exist for further lifting transmission power to ensure PDCCH biography
Defeated performance.Meanwhile, in above-mentioned PCFICH and PHICH, also there is mapping resource to fall into BWcompressedIn situation,
Performance can be ensured by strengthening transmission power.PDSCH transmission power is also to concentrate on BWnonstandardIt is allocated.Will
Transmission power is reused.
Remote Radio Unit (Radio Remote Unit, referred to as RRU) filtering transmitting.Because above-mentioned strategy is based on BWchosed,
In order to be matched with nonstandard wireless network resource, selection and BW are needed exist fornonstandardThe RRU wave filters of adaptation.I.e. in transmitting
End is using RRU filtering, it is ensured that the data and BW of transmittingnonstandardMatching.
Using the method for above-described embodiment, the bandwidth reduction based on LTE standard is realized, radio band is substantially effectively make use of
Resource, and ensure that the low damage or lossless of the performance of the LTE system of this bandwidth reduction.
In an embodiment of the present invention, Fig. 7 is the bandwidth reduction launch party according to the preferred embodiment of the invention based on LTE standard
The schematic device of method, as shown in fig. 7, the device includes：
Bandwidth adaptation module 72 (equivalent to the adaptation module 24 of above-described embodiment), for available wireless according to LTE is distributed to
The nonstandard bandwidth BW of networknonstandard, it is determined that from matching LTE standard system bandwidth BWchosed.The principle of selection
For：Select BWdistance=min (BWstandard-BWnonstandard) where BWstandard, BW herestandardFor LTE system band
Width, BWstandard={ 1.4,3,5,10,15,20 } M.Illustrate：If for example, BWnonstandard=8M, then
BWdistance=min (| [1.4,3,5,10,15,20] -8 |)=min ([- 6.6, -5, -3,2,7,12]>0)=2, so, choosing
Take BWchosed=10M；For another example BWnonstandard=16M, then BWdistance=min (| [1.4,3,5,10,15,
20] -16 |)=min ([- 14.6, -13, -11, -6,-Isosorbide-5-Nitrae]>0)=4, so, choose BWchosed=20M.
PCI screening modules 74 (equivalent to the screening module 32 of above-described embodiment), for according to BWchosedAnd BWnonstandard
The compression frequency band BW of the nonstandard bandwidth of LTE can be determinedcompressed(That is BWchosedAnd BWnonstandardFrequency band beyond common factor).According to
This, PCI (0~503) all traversal LTE, statistics PCFICH and PHICH mappings fall into BWcompressedRE probability.
PCI is screened according to two principles：1st, network planning requirement.I.e. PCI number will meet establishment cell requirement；2、
Compression frequency band falls into probability demands.I.e. according to falling into BWcompressedInterior RE probability carries out PCI sequences according to order from small to large
Screening.For example, network requirement networking PCI numbers are M, it is (from small to large) Rate to fall into rate sequence to compression frequency bandsort=
[a0,a2,…a503], correspondence PCI is PCIsort=[P0,P1,…P503].Then, the PCI of final choicechosed=[P0,P1,…PM]。

, can be by BW on the premise of line emission maximumcompressedOn power effectively utilize in BWnonstandardOn, i.e., to effective band
Data carry out power enhancing in wide.
The descending DCI of LTE carry the control information of the Traffic Channel of corresponding UE.Multiple UE DCI cascades, and in time-frequency
Interweave in resource and break up distribution.So, DCI may can fall into BW under some subframescompressed, this can cause by below
RRU filtering process, causes part RE loss of datas.Certainly, in existing LTE technologies, DCI has a variety of degree of polymerization,
DCI adaptive scheduling is realized, lifting ensures its performance.Meanwhile, also there is DCI Power Control.On the basis of prior art
Above, it is necessary to consider further that DCI RE falls into probability in compression bandwidth and further considers that power strengthens, to ensure compensation.In addition,
PCI in PCI screening modules 74chosedIn corresponding Rate sort when having nonzero value, i.e. PCFICH and PHICH also have portion
RE is divided to fall into BWcompressed, power enhancing can also be carried out to this two classes channel to ensure its property, increasing superpower principle is also
Consider that RE falls into probability in compression bandwidth.

For up, received according to 10M, actual only 8M effective bandwidth, and all valid data are all in compression bandwidth, institute
So that up bandwidth reduction ensure that the performance of all up channels, be lossless；For descending, data are entered according to 10M
Row is received.But actually active reality only has 8M.Due to a part of RE missings of compression bandwidth, only control channel, but pass through
Above-mentioned step three, four are compensated it, and performance loss is substantially lossless.The scheduling of Traffic Channel avoids compression strap completely
Width, so being that performance is also lossless.

PUCCH is in the left and right sides of LTE upstream bands, by calculating PUCCH starting location offset amount, by BWcompressedIt is empty
Out so that the scheduling of PUCCH channels is in BWchosedIt is interior.Specifically, by calculating, the PUCCH of left and right frequency band is limited
RB original position is mapped, specifically, 5 can be more than with the left frequency band RB indexes of RB indexes#, right frequency band RB indexes are small
In 94#.At the same time, PRACH and PUSCH mapping position will also do bandwidth reduction limitation, specifically, can take
6#~93#RB。
For descending：
First, it is ensured that all UE PDSCH is dispatched in compression bandwidth BWnonstandardIt is interior.As shown in figure 12, pressure is removed
Contracting bandwidth, the RB of the actual schedulable of Traffic Channel PDSCH only has 88 (available complete or collected works are scheduling to 100RB under 20M),
