Embodiment
In the business data processing based on many antennas, existing processing scheme is that the business datum that whole antenna is received is carried out a series of processing.The inventor finds under study for action, under some scene, the business datum that a part of antenna received is handled the throughput requirement that just can reach the data treatment system, and makes data handling system satisfy demand to the number of users of handling.Under such scene, if the business datum that whole antenna received is carried out a series of processing, not only increase the complexity that data handling system is handled business datum, also taken a large amount of processing resource of data handling system, caused the significant wastage of handling resource.Therefore, the embodiment of the invention provides a kind of method and apparatus that the business datum of many antennas is handled, and can adjust the complexity that data handling system is handled business datum flexibly, effectively utilizes and handles resource in the data handling system.
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
Embodiment one
See also Fig. 2, it is the flow chart of an embodiment of a kind of method that the business datum of many antennas is handled of the present invention, and this method may further comprise the steps:
Step 201: the error rate that obtains business datum;
Wherein, the error rate of described business datum comprises: the Packet Error Ratio PER of the error rate BER of the business datum of reception or the business datum of reception.
For example, the receiving cycle that receives business datum with receiving terminal is a unit, can obtain the error rate of the business datum in the receiving cycle, also can obtain the error rate of the business datum in a plurality of continuous receiving cycles.Need to prove that the embodiment of the invention did not limit the time that receives business datum, can be set a time period arbitrarily yet, obtain the error rate of the business datum of reception in this time end.
The process of each user's business datum being handled based on many antennas for convenience of description, business datum with 2 users sends by 4 transmitting antennas at transmitter below, and 4 reception antennas that are received in the machine receive, and then to carry out data processing by data handling system be that example describes.4 reception antennas in the receiver periodically receive the business datum about 2 users that transmitter sends: the business datum of user A and user B.Under some cycles, obtain the error rate of the business datum of the error rate of business datum of the user A that receives in the current period and user B respectively.
Above-mentioned business datum error rate can be BER (the Bit Error Rate of the business datum of interior user A that receives of current period and user B, the error rate), also can be the PER (Packet Error Rate, Packet Error Ratio) of the business datum of interior user A that receives of current period and user B.
Wherein, specifically can be according to the BER or the PER of CRC (Cyclic Redundancy Check, cyclic check code) service data statistics.The figure place of total business datum of the figure place/transmission of the error traffic data that BER=receives; The bag number of total business datum of the bag number/transmission of the error traffic data that PER=receives.
Step 202: when the error rate of described business datum during less than the Xiamen limit value, the number of antennas of needs being carried out business data processing is reduced to first preset number, from all reception antennas, select first preset number antenna, the business datum on the first preset number antenna is handled;
Wherein, described first preset number antenna of selecting from all reception antennas can comprise: the Signal to Interference plus Noise Ratio SINR value of calculating the business datum on each antenna; From all reception antennas, choose first preset number antenna according to described SINR value order from big to small.Perhaps can comprise: from all reception antennas, choose first preset number antenna arbitrarily.
Here, during the error rate of the business datum in obtaining some or certain several continuous receiving cycle, be reduced to first preset number if needs are carried out the number of antennas of business data processing, then can rise the business datum on the first preset number antenna is handled, also can in preset time, handle the business datum on the first preset number antenna at next cycle.As, the error rate of the business datum in obtaining 1-5 receiving cycle, and when the number of antennas that needs carry out business data processing is reduced to first preset number, can begin only the business datum on the first preset number antenna to be handled at the 6th receiving cycle; And then obtain the error rate of the business datum in 6-10 the receiving cycle, if still the number of antennas of carrying out business data processing can be maintained first preset number according to error rate, then begin only the business datum on the first preset number antenna to be handled, by that analogy ... .. at the 11st receiving cycle.
For example, be example still with above-mentioned scene, when the error rate of business datum was the BER of business datum, corresponding Xiamen limit value was a BER Xiamen limit value, when the error rate of business datum was the PER of business datum, corresponding Xiamen limit value was a PER Xiamen limit value.Be identified as example with the BER to the business datum of user A below, when the BER value of the business datum of user A during less than BER Xiamen limit value, the number of antennas of needs being carried out business data processing is reduced to first preset number.At first with the user A SINR of the business datum on 4 reception antennas (Signal to Interference plus Noise Ratio respectively, Signal to Interference plus Noise Ratio) value sorts according to from big to small order, if first preset number is 2, from 4 reception antennas, select 2 maximum reception antennas of SINR value again.In the prior art, after utilizing 4 reception antennas to receive the business datum of user A, the number of antennas that need carry out business data processing is 4.In the present embodiment, after utilizing 4 reception antennas to receive the business datum of user A, according to setting, need carrying out the sky of business data processing, to keep count of be 2, and be 2 maximum reception antennas of SINR value of the business datum from 4 reception antennas, selected, when next cycle is handled the business datum on each antenna, only need handle the business datum on these 2 reception antennas.Equally,, also carry out data processing, repeat no more herein with identical scheme when the BER value of the business datum of user B during less than BER Xiamen limit value.It is to be noted, the business datum of different user is the branch processing of coming in the present embodiment, the business datum that is to say user A and user B is the branch transmission of coming on antenna, can't transmit simultaneously, when the business datum of transmission user A, use the number of antennas under the user A, when the business datum of transmission user B, use the number of antennas under the user B.
Except can discerning to the BER of the business datum of user A and user B, can also the PER of the business datum of user A and user B be discerned, promptly as the PER of the business datum of user A and user B during less than PER Xiamen limit value, according to such scheme the number of antennas that needs carry out business data processing is reduced to first preset number, and the business datum on the first preset number antenna is handled in following one-period.
Perhaps, also can be not according to SINR value selective sequential antenna from big to small, but from all reception antennas, choose the first preset number antenna arbitrarily.For example when the performance of all reception antennas is close, can from all reception antennas, chooses the first preset number antenna arbitrarily, and the business datum on the first preset number antenna of choosing arbitrarily be handled in following one-period.As, when first preset number is 2, from 4 reception antennas, select 2 reception antennas wherein arbitrarily, in following one-period the business datum on these 2 reception antennas is handled.
The above-mentioned user A SINR value of the business datum on 4 reception antennas respectively can adopt any existing computational methods to calculate, and the embodiment of the invention does not limit this.For example, specifically can obtain in the following way: earlier the pilot signal that receives according to the pilot channel estimation value of 4 reception antennas and 4 reception antennas respectively calculates the interference noise of 4 reception antennas; Calculate the user A SINR value of the business datum on 4 reception antennas respectively according to the interference noise of 4 reception antennas, the pilot signal of 4 reception antenna receptions and the pilot channel estimation value of 4 reception antennas respectively again.
Certainly, also can obtain the SINR value of the business datum of user A on 4 reception antennas in other way.
Alternatively, when the error rate of business datum is not less than the Xiamen limit value, the number of antennas that need carry out business data processing can remain unchanged, for example when the business datum on all reception antennas is handled, if the error rate of business datum is not less than the Xiamen limit value, still the business datum on all reception antennas is handled, repeated no more herein.
In addition, after the number of antennas of needs being carried out business data processing is reduced to first preset number, described method can further include: when the error rate of described business datum during greater than upper threshold, the number of antennas of needs being carried out business data processing increases to second preset number, from all reception antennas, select second preset number antenna, business datum on second preset number antenna of selecting is handled, described second preset number is greater than described first preset number, and is less than or equal to the reception antenna number.
After the number of antennas of needs being carried out business data processing is reduced to first preset number,, then the number of antennas of carrying out business data processing can be maintained first preset number if the error rate of described business datum is less than or equal to upper threshold.
For example, after the number of antennas of needs being carried out business data processing is reduced to first preset number, the error rate of the business datum of reentrying, whether the error rate of judging business datum is greater than upper threshold, under the situation that the business datum on the first preset number antenna is handled, if the error rate of business datum is greater than upper threshold, the number of antennas of then again needs being carried out business data processing increases to second preset number, and the business datum on the second preset number antenna is handled; Under the situation that the business datum on the first preset number antenna is handled,, then continue the business datum on the first preset number antenna is handled if the error rate of business datum is less than or equal to upper threshold.Here, second preset number is greater than first preset number, and is less than or equal to the reception antenna number.
Wherein, described second preset number antenna of selecting from all reception antennas comprises: the SINR value of calculating the business datum on each antenna; From all reception antennas, choose second preset number antenna according to described SINR value order from big to small.
Here, during the error rate of the business datum in obtaining some or certain several continuous receiving cycle, increase to second preset number if needs are carried out the number of antennas of business data processing, then can rise the business datum on the first preset number antenna is handled, also can handle the business datum on the first preset number antenna behind the preset time at next cycle.As, the error rate of the business datum in obtaining the 1st receiving cycle, and when the number of antennas that needs carry out business data processing increased to second preset number, in 2-5 receiving cycle, the business datum on the second preset number antenna is handled; And then obtain the error rate of the business datum in the 6th receiving cycle, if the number of antennas that still needs to carry out business data processing increases to second preset number, then in 7-10 receiving cycle, only the business datum on the second preset number antenna is handled.
For example, still be identified as example with the BER to the business datum of user A below, when the BER value of the business datum of user A during greater than the BER upper threshold, the number of antennas of needs being carried out business data processing increases to second preset number.As, through adjustment before, the number of antennas that current needs carry out business data processing is 2.At first with user A respectively the SINR value of the business datum on 4 reception antennas sort according to from big to small order, if second preset number is 3, then from 4 reception antennas, select 3 reception antennas of SINR value maximum.In the prior art, after utilizing 4 reception antennas to receive the business datum of user A, the number of antennas that need carry out business data processing is 4.In the present embodiment, after utilizing 4 reception antennas to receive the business datum of user A, and according to setting, need carrying out the sky of business data processing, to keep count of be 3, and be 3 maximum reception antennas of SINR value of the business datum from 4 reception antennas, selected, when next cycle is handled the business datum on each antenna, only need handle the business datum on these 3 reception antennas.Equally,, also carry out data processing, repeat no more herein with identical scheme when the BER value of the business datum of user B during greater than the BER upper threshold.
Except can discerning to the BER of the business datum of user A or user B, can also the PER of the business datum of user A or user B be discerned, promptly as the PER of the business datum of user A or user B during greater than the PER upper threshold, according to such scheme the number of antennas that needs carry out business data processing is increased to second preset number, and the business datum on the second preset number antenna is handled.
Perhaps, also can from all reception antennas, choose second preset number antenna arbitrarily not according to SINR value selective sequential antenna from big to small.For example when the performance of all reception antennas is close, can from all reception antennas, chooses the second preset number antenna arbitrarily, and the business datum on the second preset number antenna of choosing arbitrarily be handled in following one-period.As, when second preset number is 3, from 4 reception antennas, select 3 reception antennas wherein arbitrarily, in following one-period the business datum on these 3 reception antennas is handled.
Need to prove that above-mentioned upper threshold is all relevant to the business datum error rate performance requirement of receiver with the user with the Xiamen limit value.Specifically can be: but but be that receiver is set BER tolerance range or PER tolerance range by the user according to user demand earlier to receiver.As according to user demand but the BER tolerance range of receiver being set at 0.01%-0.1%, can determine according to this scope: BER Xiamen limit value is 0.01%, and the BER upper threshold is 0.1%.Certainly, when the user has higher the requirement to the BER performance of receiver, but can set other BER tolerance range.
After but the BER of receiver tolerance range is determined, set first preset number at the Xiamen limit value again, for example set first preset number by the mode of experiment test repeatedly, promptly, when the number of antennas of needs being carried out business data processing is reduced to a certain numerical value, when the BER performance of receiver also can satisfy this Xiamen limit value and requires, be about to this moment value corresponding and be set at first preset number.Equally, at upper threshold, also can set second preset number by the mode of experiment test repeatedly, promptly, when the number of antennas of needs being carried out business data processing increases to a certain numerical value, when the BER performance of receiver also can satisfy this upper threshold requirement, being about at this moment, value corresponding was set at second preset number.Certainly, but except determining first preset number and second preset number by the BER tolerance range, but also can determine first preset number and second preset number, but it determines that method can be referring to the above-mentioned method of determining according to the BER tolerance range by the PER tolerance range.
As can be seen from the above-described embodiment, if the error rate of the business datum that receives less than the Xiamen limit value, the number of antennas of just needs being carried out business data processing is reduced to first preset number, so that the business datum on the first preset number antenna is being handled.Thereby realize carrying out the dynamic adjustment of number of antennas, adjust the complexity that data handling system is handled business datum flexibly, effectively utilize the processing resource in the data handling system based on the error rate of business datum.
Simultaneously, also reduce the load factor of data handling system, made data handling system reach energy-conservation effect.
