The embodiment of the invention provides a kind of resource allocation methods, access network equipment and communication system, and the resource scheduling algorithm through adjustment terminal upstream data helps reducing the hardware cost at terminal.
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Embodiment one,
See also Fig. 1, a kind of resource allocation methods of the embodiment of the invention one can comprise:
110, obtain the current transmitting power in terminal that is in first system, first uplink band is used in the sub-district that this terminal is inserted.
In practical application, can obtain the current transmitting power in terminal in several ways, for example can be according to the maximum transmission power (P at terminal
Max) and the power headroom (PHR, Power HeadRoom) of terminal to report, the transmitting power (P that computing terminal is current
Max-PHR), wherein PHR is meant the difference of transmitting power and maximum power.
120, whether judge the above-mentioned transmitting power of obtaining greater than the first preset power threshold, if, execution in step 130; If not, but execution in step 140.
The transmitting power that is appreciated that terminal under the equal conditions is big more, and is also just big more usually to the interference at the signal of successive bands transmission.In practical application, can come to preset the size of first power threshold as required, for example can the size of first power threshold be preset as 20dBm.
130, be the ascending resource piece of the upstream data dividing frequency at terminal away from second frequency range of second system use, wherein, the frequency interval of second frequency range and first uplink band satisfies frequency preset condition at interval.
Wherein, current area can be claimed in the sub-district that the terminal is inserted, and is corresponding, and the wireless communication system that the terminal is inserted can be claimed current system.Second system can adopt different standards with first system; The up working frequency range (first uplink band) of the sub-district that second frequency range and above-mentioned terminal are inserted if frequency interval satisfy frequency preset condition at interval; The possibility that then produces larger interference is also bigger; In this case, can be the upstream data dividing frequency at terminal ascending resource piece away from second frequency range.
Concrete; The frequency interval of second frequency range and first uplink band satisfy frequency preset at interval definite mode of condition for example can be: whether the frequency interval through judging second frequency range and first uplink band confirms whether the frequency interval of second frequency range and first uplink band satisfy frequency preset interval condition less than preset first frequency interval threshold.If the frequency interval of second frequency range and first uplink band is less than this preset first frequency interval threshold; The frequency interval of then determining second frequency range and first uplink band satisfies frequency preset condition at interval; Otherwise the frequency interval of determining second frequency range and first uplink band does not satisfy frequency preset condition at interval.
Be appreciated that the size of the frequency interval of two frequency ranges, with being directly connected to the interference between signals size of on two frequency ranges, transmitting.In practical application; Can set the size of first frequency interval threshold according to concrete application scenarios; And then can specifically confirm the strategy of resource allocation according to the frequency interval of the up working frequency range of second frequency range and current area whether less than this first frequency interval threshold.
On the other hand, in practical application, can be embodied as the ascending resource piece of the upstream data dividing frequency at terminal in several ways away from second frequency range of second system use.
Under a kind of application scenarios; For example; Can be from the maximum available ascending resource BOB(beginning of block) of the frequency interval of the frequency values and second frequency range; Judge successively whether the ascending resource piece satisfies the signal to noise ratio judgment condition, wherein, the signal to noise ratio judgment condition is that the signal to noise ratio of ascending resource piece is greater than the first preset snr threshold; Select to satisfy at first one or more ascending resource pieces of above-mentioned signal to noise ratio judgment condition, the ascending resource piece of selecting is distributed to above-mentioned terminal.
Under another kind of application scenarios; For example; Can preset another one frequency interval threshold value (can be called the second frequency interval threshold) as the case may be earlier; From the available ascending resource piece of frequency interval greater than this preset second frequency interval threshold of the frequency values and second frequency range, select to satisfy one or more ascending resource pieces of above-mentioned signal to noise ratio judgment condition, the ascending resource piece of selecting is distributed to above-mentioned terminal.
Again on the one hand, can set the size of first signal to noise ratio (SNR, Signal Noise Ratio) threshold value as required.
In addition, distribute about the ascending resource piece, can be through relevant signaling, the time domain of the ascending resource piece that will distribute and frequency domain position notice terminal for the upstream data at terminal, the terminal is at the ascending resource piece transmit ascending data that is its distribution.
It is far away that the strategy of above-mentioned resource allocation can realize that the frequency interval of second frequency range that frequency and second system of terminal transmission upstream data use is tried one's best, and also just helps reducing or avoid the mutual interference mutually between the transmission signals on second frequency range of terminal transmission upstream data and the use of second system.
140, according to existing procedure be the upstream data distribution ascending resource piece at terminal.
Concrete, can distribute the one or more ascending resource pieces of signal to noise ratio for the upstream data at terminal in this step greater than the first preset snr threshold.
Certainly, when the upstream data that is the terminal distributes the ascending resource piece, can also distribute with reference to other a plurality of relevant parameters simultaneously.
Need to prove; First system in the embodiment of the invention and second system adopt the communication system of following any two standards respectively: PHS, LTE, global system for mobile communications (GSM; GlobalSystem for Mobile communication), code division multiple access inserts (CDMA; Code DivisionMultiple Access), 3-G (Generation Three mobile communication system) (3G; 3rd Generation Mobilecommunication), Wimax, WiFi, the embodiment of the invention be not limited to above-mentioned for example.
Need to prove; Above-mentioned steps can practical implementation on the access network equipment of communication system; Above-mentioned access network equipment can be that other has and is equal to or the equipment of identity function in base station (base station in the LTE system can be called enhanced base station), base station controller, access point or the communication system; The terminal can be that relay station (RS, Relay Station), subscriber equipment (for example mobile phone) or other have and be equal to or the receiving equipment of identity function, and the embodiment of the invention is not done qualification.
Can find out by technique scheme; The embodiment of the invention is obtained and is judged that whether the current transmitting power in terminal is greater than a certain setting threshold; In the transmitting power at terminal during greater than a certain setting threshold; The strategy of adjustment resource allocation is the ascending resource piece of the upstream data dividing frequency at terminal away from the successive bands that is taken by other standard system as far as possible, helps reducing the mutual interference of adjacent system; Owing to be to solve with adjacent interference problem frequently through the adjustment resource allocation policy, also just can not need the terminal to select the very high hardware filtering device of performance for use, the prior art of comparing can reduce the hardware cost at terminal.
Buy execute the example two,
For ease of better understanding the technical scheme that the embodiment of the invention provides; Below with the A of system take frequency range a1, system B takies frequency range b1 (wherein; System A and the B of system are the wireless communication system of different systems, and frequency range a1 is adjacent with frequency range b1), the transmitting power size that the base station of system A is current according to the terminal; The process of carrying out resource allocation flexibly is an example, carries out further detailed description.
See also Fig. 2, a kind of resource allocation methods of the embodiment of the invention two can comprise:
201, the base station obtains the current transmitting power in terminal.
Wherein, to obtain the mode of terminal current transmit power can be diversified in the base station.
Under a kind of application scenarios, in each subframe, the terminal can be real-time reports current PHR, and the base station can be according to the maximum transmission power P at terminal
MaxWith the current PHR that reports in terminal, get access to terminal current transmitting power (transmitting power=P that the terminal is current
Max-PHR).
202, whether the transmitting power obtained of base station judges greater than preset power threshold W1, if, get into step 203, if not, get into step 205.
Wherein, Under equal conditions; The transmitting power at terminal is big more, and is also just big more usually to the interference at the signal of successive bands transmission, so the base station can be preset the size of power threshold W1 as required; To the magnitude relationship of the current transmitting power in terminal, select the different resources allocation strategy flexibly with preset power threshold W1.
In practical application, the size of its preset power threshold W1 can be adjusted, to satisfy the different scene needs flexibly according to different application scenes in the base station.
For instance, if the transmitting power scope at terminal is-45dBm～25dBm that the size of the power threshold W1 that the base station is preset can be 15dBm, 20dBm, 22dBm or other value, does not do qualification here.
203, base station judges frequency range b1 and terminal insert the sub-district the frequency interval of up working frequency range whether less than frequency preset interval threshold F1, if, execution in step 204, if not, execution in step 205.
Be appreciated that; The up working frequency range of current area can be the some or all of of the shared frequency range a1 of the A of system; When the frequency interval of the up working frequency range of shared frequency range b1 of the B of system and current area less than frequency preset interval threshold F1, just can consider the problem of phase mutual interference.The base station can be according to the mutual disturbed condition under the different scenes; The size of predeterminated frequency interval threshold F1 flexibly; To the frequency interval of the up working frequency range of frequency range b1 and current area and the magnitude relationship of frequency preset interval threshold F1, select the different resources allocation strategy flexibly.
Need to prove that step 203 and step 202 do not have inevitable existing order, also can first execution in step 203, execution in step 202 again.
Further; If the base station has been known the relation of the frequency interval and the frequency interval threshold value F1 of frequency range b1 and terminal present access subzone in advance; Then step 203 can be omitted, and that is to say, if the current transmitting power in the base station judges terminal that goes out to obtain is greater than preset power threshold W1; And the frequency interval of up working frequency range that inserts the sub-district in frequency range b1 and terminal has been known in advance less than frequency preset interval threshold F1 in the base station, then direct execution in step 204; If the frequency interval of up working frequency range of frequency range b1 and terminal access sub-district has been known in advance greater than frequency preset interval threshold F1 in the base station, but execution in step 205 then.
204, if the transmitting power at terminal greater than preset power threshold W1; And the frequency interval of the up working frequency range of frequency range b1 and current area is less than frequency preset interval threshold F1, and the base station is that the upstream data dividing frequency at terminal is tried one's best away from the ascending resource piece of frequency range b1.
For instance, the size of base station frequency preset interval threshold F1 can be 1MHz, 10MHz, 20MHz or other value, does not do qualification here.
In practical application; Can be accomplished in several ways into the upstream data dividing frequency at terminal as far as possible away from the ascending resource piece (RB of frequency range b1; Resource Block); And then reduce with the neighbour as far as possible and disturb frequently, the base station can be distributed with reference to a plurality of relevant parameters, for example base station reference simultaneously: ascending resource piece to be allocated (can use up Resource Block) is big or small with the frequency interval of frequency range B1, current SNR and other the one or more relevant parameters of ascending resource piece to be allocated.
Wherein, The base station can be more real-time the current SNR of each ascending resource piece to be allocated of acquisition; A snr threshold S1 can further be preset in the base station, compares with preset snr threshold S1 through the SNR with each ascending resource piece to be allocated, guarantees to be assigned to the available ascending resource piece of SNR greater than preset snr threshold S1 for the upstream data at terminal; To ensure the quality of transfer of data, reduce the error rate.
Under a kind of application scenarios, the base station can for the upstream data priority allocation frequency at terminal as far as possible away from frequency range b1 and SNR available ascending resource piece greater than preset SNR threshold value S1.
For instance; Can set another frequency interval threshold value F2 as the case may be; The base station can select the frequency interval of frequency and frequency range b1 greater than frequency interval threshold value F2, and SNR is greater than the ascending resource piece of preset SNR threshold value S1, and the ascending resource piece of selecting is distributed to the terminal.Be appreciated that this mode implementation algorithm is simple relatively, the implementation complexity of resource allocation process is lower, realizes relatively easy.
Wherein, if having a plurality of ascending resource pieces to be allocated that satisfy distributive condition, base station can select wherein part ascending resource piece to distribute to the upstream data at terminal according to actual needs.It is understandable that the ascending resource piece of selection can be one or more.
Again for instance; Frequency range b1 available ascending resource BOB(beginning of block) farthest also can preferentially be left from frequency in the base station; Whether the SNR that judges each ascending resource piece successively is greater than preset SNR threshold value S1; And select to satisfy at first SNR greater than preset SNR threshold value S1 from one or more ascending resource pieces, the ascending resource piece of selecting is distributed to the terminal.Be appreciated that this mode can help reducing to greatest extent with adjacent disturbing frequently to greatest extent for the upstream data at terminal is assigned to frequency from frequency range b1 ascending resource piece farthest.
205, the base station is the upstream data distribution ascending resource piece at terminal according to existing procedure.
The situation of carrying out this step is: if the frequency interval of the up working frequency range of frequency range b1 and current area is more than or equal to frequency preset interval threshold F1, or the current transmitting power in terminal is less than or equal to preset power threshold W1.In this step, the base station can be according to existing procedure or mode, according to the size of the SNR of each Resource Block to be allocated, for the upstream data at terminal distributes the SNR big one or more ascending resource pieces of trying one's best, and need not consider the problem of frequency size or frequency interval.
Certainly, resource allocation also can also be carried out with reference to other parameter simultaneously in the base station.
Further, the base station can utilize relevant letter modern, the time domain of the ascending resource piece that will distribute for the upstream data at terminal and frequency domain position notice terminal.
The terminal is utilized as the ascending resource piece that its upstream data distributes, transmit ascending data after the time domain and frequency domain position of knowing the ascending resource piece that the base station is distributed for its upstream data.
The base station can be according to aforesaid way, and according to the dynamic change of actual conditions, the relatively reasonable resource allocation policy of real-time selection is that the upstream data at each terminal distributes the ascending resource piece, to guarantee that resource allocation in real time rationally effectively.
For ease of better understanding the technique scheme of present embodiment, through instantiation the technical scheme of the embodiment of the invention is done further detailed explanation below.
For instance, if said system A is the LTE system, frequency range a1 is LTE UE BANDl frequency range (UL:1920MHz～1980MHz; DL:2110MHz～2170MHz), system B are PHS, the scope of frequency range b1: 1884.5MHz～1919.6MHz.
Serve as that the process that inserts the terminal distribution resource of LTE system is an example with the base station of LTE system below, describe.Wherein, be example with base station preset power threshold W1=20dBm, frequency interval threshold value F1=30MHz, snr threshold S1=40dB.
At first, the PHR that the base station can report in current subframe according to the terminal is in conjunction with the maximum transmission power P at terminal
MaxThe transmitting power that computing terminal is current.
Certainly, the base station also can select alternate manner to obtain the current transmitting power in terminal, does not do qualification here.
Whether the current transmitting power in the terminal that base station judges is obtained is greater than W1 (20dBm).
If; And the up working frequency range of current area is 1920MHz～1940MHz ((1920MHz-1919.6MHz=0.4MHz)＜F1 (30MHz)); The frequency interval that is the up working frequency range of current area and the frequency range that PHS takies is less than frequency preset interval threshold F1, and the base station can be that the upstream data dividing frequency at terminal is as far as possible away from frequency range b1 (1919.6MHz) and the SNR ascending resource piece greater than S1 (40dB).
For instance, the base station can be preferentially from from frequency range b1 (1919.6MHz) ascending resource piece (being the ascending resource piece that frequency is positioned at 1940MHz) beginning farthest, for the upstream data at terminal distributes the ascending resource piece of SNR greater than 40dB.
If the up working frequency range of current area is 1960MHz～1980MHz ((1960MHz-1919.6MHz=40.4MHz)＞F1 (30MHz)); The frequency interval that is the up working frequency range of current area and the frequency range that PHS takies is greater than frequency preset interval threshold F1; The SNR of each ascending resource piece to be selected can be compared in the base station, for the upstream data at terminal distributes the SNR big one or more ascending resource pieces of trying one's best.Certainly, resource allocation also can also be carried out with reference to other parameter simultaneously in the base station.
If the up working frequency range of current area is 1940MHz～1960MHz; The frequency interval of lower-frequency limit and the frequency range that PHS takies of up working frequency range that is current area is less than frequency preset interval threshold F1; And the frequency interval of the frequency range that the upper frequency limit of the up working frequency range of current area and PHS take is greater than frequency preset interval threshold F1; At this moment, the base station upstream data that can to select above-mentioned two kinds of resource allocation policies flexibly be the terminal distributes the ascending resource piece.
The base station can further utilize relevant signaling, the time domain of the ascending resource piece that will distribute for the upstream data at terminal and frequency domain position notice terminal.The terminal is utilized as the ascending resource piece that its upstream data distributes, transmit ascending data after the time domain and frequency domain position of knowing the ascending resource piece that the base station is distributed for its upstream data.
The base station can be according to aforesaid way, corresponding each subframe, and selecting relatively reasonable resource allocation policy is the ascending resource piece (RB, Resource Block) of the upstream data distribution at each terminal, to guarantee that resource allocation is in real time rationally effectively.
For instance; In each subframe, relatively reasonable resource allocation policy can be selected according to aforesaid way in the base station; Carry the Physical Uplink Shared Channel (PUSCH of the upstream data at terminal for each terminal can be used for of using; Physical uplink shared channel) distributes resource blocks is to guarantee that resource allocation in real time rationally effectively, reduces as far as possible with adjacent and disturbs frequently.
Be appreciated that said system A and said system B can be the systems that adopts following any two kinds of standards respectively: LTE, PHS, GSM, CDMA, 3G, Wimax, WiFi, and be not limited to above-mentioned giving an example.
Need to prove, present embodiment be with the base station according to condition of different, selecting the different resources allocation strategy is that example describes for the terminal distribution Resource Block, certain above-mentioned base station also can be that other has and is equal to or the equipment of identity function in the communication system.
Can find out by technique scheme; The present embodiment base station obtain and the transmitting power of judging the terminal whether greater than a certain setting threshold; In the transmitting power at terminal during greater than a certain setting threshold; The strategy of base station adjustment resource allocation is the ascending resource piece of the upstream data dividing frequency at terminal away from the successive bands that is taken by other standard system as far as possible, helps reducing mutual interference; Because be that adjacent together frequency interference problem is solved through adjusting resource allocation policy in the base station, high performance filter can not need be selected in the terminal, the prior art of comparing helps reducing the hardware cost at terminal.
Further, the base station can be as the case may be, and selecting corresponding resource allocation policy flexibly is the terminal distribution Resource Block, can be applicable to plurality of application scenes.
