Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
The technical solution provided below in conjunction with attached drawing, each embodiment that the present invention will be described in detail.
As shown in Figure 1, the big data transmission of the communication system uses MIMO technology by taking WIFI MIMO communication system as an example,
And when carrying out the link maintenances message lower rate transmissions such as ACK, Beacon, low rate can be used in the centre of high speed transmission data
The communication data packets such as modulate emission ACK or Beacon.
Normal MIMO communication, can insert the transmission of the basic links such as ACK and Beacon communication, and work as MIMO among data
When communication quality is bad to cause packet loss serious, it is also desirable to which the subsequent data transmission of system is switched to SISO or replaces it by system
His antenna carries out transmission progress.
As shown in Figure 1, in the state that antenna is in normal, after the communication data packets such as transmitting ACK or Beacon, antenna
Data are transmitted, the communication data packets such as ACK or Beacon then can be received, at this point, can indicate that antenna does not deteriorate.If antenna
Deteriorate, then after the communication data packets such as transmitting ACK or Beacon, as shown in Fig. 2, antenna can lose one when transmitting data
A little data, and the communication data packets such as ACK or Beacon will not be received, at this time, it may be determined that antenna has occurred and that deterioration, then
Single antenna circuit is switched to again to be communicated.
Thus it is not difficult to find that by using Packet Error Ratio, retransmission rate, time delay, the finger calibration method detecting such as received signal strength
When antenna environment and isolation, needs to lose a certain amount of data as cost, can just detect the deterioration of isolation between antennas,
Just to be adjusted accordingly after deterioration.
In order to solve the above technical problems, the embodiment of the present invention proposes that a kind of antenna uses the determination method of strategy, it is applied to

One-way isolation degree between antenna and the second antenna, and/or, the radiation efficiency of first antenna and the second antenna；
Step 304. is determined to the antenna in terminal device according to status information using strategy.
Since antenna first obtains the status information between first antenna and the second antenna using the determination method of strategy, then
According to the first antenna in status information and the one-way isolation degree between the second antenna, and/or, first antenna and the second antenna
Radiation efficiency is determined to the antenna in terminal device using strategy, to realize signal using strategy according to identified antenna
Transmission.In this way, determining first by the status information between the first antenna and the second antenna of acquisition before carrying out signal transmission
Whether antenna and the second antenna deteriorate, to determine the use plan to the antenna in terminal device when antenna deteriorates
Slightly, so that not only communication quality can be influenced to avoid since antenna occurs to deteriorate, and can shift to an earlier date according to antenna every
It is adjusted from behaviour in service of the state to antenna.Therefore, it can solve and need to lose a certain amount of data in the prior art
It can detect that the problem of isolation between antennas deteriorates.
I.e. the method for the embodiment of the present invention can judge antenna environment based on device systems itself, send in system
Antenna environment and isolation state can be learnt before data, and then can adjust and correct in advance the use shape of antenna
Condition carries out the switching (such as WIFI interferes with diversity antenna, and LTE can be switched to main collection antenna) of antenna in time, or adjusts
The sending mode of whole MIMO or SISO avoids the deterioration shadow because of the isolation between the radiation efficiency and multiple antennas of antenna
It rings and arrives signal communication quality.
In the above-described embodiments, step 306 according to status information, determine the use plan to the antenna in terminal device
Slightly, comprising: if the first space isolation, second space isolation are matched with isolation threshold value, it is determined that use multi-antenna transmitting
Defeated signal, the first space isolation are unidirectional between first antenna and the second antenna when first antenna transmission link safeguards data
Isolation, second space isolation are unidirectional between the second antenna and first antenna when the second antenna transmission link safeguards data
Isolation；If the first space isolation and isolation threshold value mismatch and/or second space isolation and isolation threshold value not
Match, then the second radiation efficiency of the first radiation efficiency based on first antenna and the second antenna, determines in the terminal device
Antenna using strategy.
It should be understood that can determine first when the first space isolation, second space isolation are matched with isolation threshold value
Antenna and the second antenna do not deteriorate, at this point, since it is determined that first antenna and the second antenna condition are in good, because
This, can be used the multi-antenna transmission signal being made of first antenna and the second antenna.If the deterioration of antenna, which is not above, to be connect
The range received, the then antenna deteriorated at this time also can be used for transmission data.Therefore, empty in the first space isolation and second
Between any of isolation when being mismatched with isolation threshold value, then explanation deteriorates with the unmatched antenna of isolation threshold value,
At this point, the day of deterioration can be further determined that according to the first radiation efficiency of first antenna and the second radiation efficiency of the second antenna
Whether line can be used multi-antenna transmission signal, to use strategy transmission signal by determining antenna.
That is, in a further embodiment, the second radiation of the first radiation efficiency and the second antenna based on first antenna
Efficiency is determined to the antenna in terminal device using strategy, comprising:
If the first radiation efficiency and the second radiation efficiency are all larger than or are equal to efficiency preset value, it is determined that use multi-antenna transmitting
Defeated signal；Radiation efficiency is less than the target antenna of efficiency preset value if it exists, then closes target antenna and determine using except target
Other antenna transmission signals except antenna.Wherein, target antenna is that radiation efficiency is less than effect in first antenna and the second antenna
The antenna of rate preset value.
It is understood that determining that there is a situation where deteriorate for at least antenna in first antenna and the second antenna
Under, according to the second radiation efficiency of the first radiation efficiency of first antenna and the second antenna, it is determined whether meet and use multiple antennas
(being made of first antenna and the second antenna) transmits the condition of signal, and in the case where meeting multi-antenna transmission signal conditioning,
It is using the multi-antenna transmission signal, and in the case where being unsatisfactory for multi-antenna transmission signal conditioning, then small using radiation efficiency is removed
Other antenna transmission signals except the antenna of efficiency preset value.In this way, not only can occur to deteriorate ratio to avoid due to antenna
It is more serious and influence communication quality, and can shift to an earlier date and the behaviour in service of antenna is adjusted according to the isolation of antenna
It is whole, solve the problems, such as that needing to lose a certain amount of data in the prior art just can detect that isolation between antennas deteriorates.
By taking 2*2MIMO system (namely antenna uses the determination system of strategy) as an example, as shown in figure 4, the system includes A0
And A1Two antennas respectively correspond two antenna circuit Chian0 (with the match circuit M of itself0) and Chian1 (have itself
Match circuit M1), and the radiating element gross efficiency of antenna and match circuit composition is E0, from A0Space is to A1The isolation in space
Spending is I, and match circuit MOAnd M1Reflection coefficient is respectively R0And R1.Directional coupler C is set in each antenna circuit0And C1,
Its detection direction is just for signal energy received by the reflected watt level of match circuit and the antenna circuit
Size.The power that transmitting receiving unit in system is emitted is P1And P0It is controllable and known.
Work as P0When transmitting, transmitting signal passes through A0Reach A1Enter after Chain1 afterwards, is detected via directional coupler
Signal strength is denoted as R01, and by M0The power flag for reflecting Chian0 is R00；Similarly, work as P1When transmitting, emit signal by day
Line A1Reach antenna A0Enter after Chain0 afterwards, is denoted as R via the signal strength that directional coupler detects10, and by M1Reflection
The power flag for returning Chain1 is R11。
That is, antenna circuit is double antenna circuit in said one specific embodiment, as shown in figure 5, obtaining first day
The status information of line and the second antenna, comprising:
First reflection power R of step 502. acquisition first antenna circuit00And second antenna circuit receive by first day
The first of the link maintenance data of line transmission receives power R01。
Step 504. obtains the second reflection power R of the second antenna circuit11And first antenna circuit was received by second day
The second of the link maintenance data of line transmission receives power R10。
Step 506. is based on the first reflection power R00, first receive power R01, the second reflection power R11And second receive
Power R10, determine the first space isolation I01With second space isolation I10。
Wherein it is determined that the first space isolation I01With second space isolation I10Operation may also include that
Step 602. is based on the first reflection power R00With the second reflection power R11, determine the first radiation effect of first antenna
Rate E0With the second radiation efficiency E of the second antenna1。
Step 604. is based on the first radiation efficiency E0, the second radiation efficiency E1, first receive power R01And second receive
Power R10, determine the first space isolation I01With second space isolation I10。
Still it is illustrated in conjunction with Fig. 4, in the ACK launching phase time slot of communication transfer first antenna circuit Chian0,
The signal power that the road Chain0 issues is P0, which can be in M0Place carries out a part of reflection, and a part passes through first antenna A0Hair
It is incident upon space.Wherein, pass through directional coupler C0Available first reflection power is R00, the power for being radiated to space is P0*
E0, the signal energy in space is radiated to by two aerial loss isolation I (I01, it is isolated in terms of Chain0 to the space of Chain1
Degree) after, pass through the second antenna A1The signal is received, which enters the second antenna circuit Chain1, and by Chain1
Directional coupler C1It is R that the reception power, which can be detected,01。
It can similarly obtain, in the second antenna circuit Chain1 with P1After transmission power issues ack signal, by Chain1
Directional coupler C1Reflected energy R can be obtained11, Chain1 emitted energy is using antenna A1After transmitting, by the sky between two antennas
Between isolation I (I10, to the space isolation of Chain0 in terms of Chain1), by the antenna A in Chain00It receives, at this point, passing through
Directional coupler C in Chain00It is R that the power, which can be detected,10.Parameter R as a result,00, R01, R11, R10It can get.
Due to R00, R01, R11, R10At this time it is known parameters, and emits the power P that receiving unit is emitted1And P0For
Know, therefore, by formula: R00=P0*(1-E0), R01=(P0*E0-I01)*E1, R11=P1*(1-E1), R10=(P1*E1-I10)*E0
It is available:
E0=1-R00/P0；
E1=1-R11/P1；
I01=P0-R00-(R01*P1)/(P1-R11)；
I10=P1-R11-(R10*P0)/(P0-R00)。
So far, the unidirectional space isolation I between two antennas01And I01And the efficiency E of two antennas0And E1?
Through obtaining.In this way, can be according to space isolation I01And I01And the efficiency E of two antennas0And E1Judge the independence of two antennas
State and isolation state, so that it is determined that signal transmission strategy.
That is, by by unidirectional space isolation I01And I01It is compared respectively with isolation preset value, determines two
Whether branch antenna deteriorates, in the case where deteriorating, then by by the efficiency E of two antennas0And E1It is pre- with efficiency respectively
If value is compared, to determine the separate state of two antennas, and then determine to carry out signal transmission using SISO or MIMO technology,
Or the movement such as mimo antenna selection or increase or reception power is carried out, and then avoid or compensate since antenna environment leads to antenna
Efficiency decline or isolation deteriorate, thus the problem of actual use to user brings adverse effect.
Specifically, if C0Or C1Antenna appearance causes its efficiency to decline due to external environment, can be switched by control system
For SISO transmission；If C1Antenna condition deteriorates serious, mimo system can be switched to C before MIMO data are sent next time again0
The SISO system of antenna is transmitted.Conversely, if C0Antenna condition deteriorates seriously, can just will before MIMO data are sent next time again
Mimo system is switched to C1The SISO system of antenna is transmitted.
In this way, can need to lose a part of data packet to avoid as shown in Figure 2 just and would know that asking for mimo antenna circuit
Topic, can know mimo antenna circuit condition in advance, with occur deterioration or efficiency it is relatively low when Pre-handoff, avoid by
In the problem that lost data packets cause user experience bad.
If C0And C1Acute variation has occurred in isolation between two antennas, then the mutual interference and correlation of two transmission links
Significant change will occur, the variation can be detected after two ack msg packet periods under the conditions of meeting MIMO, in turn
Adjustment antenna (such as selects other antennas to combine as MIMO, or closes a wherein antenna circuit), solves due to isolation
The problem of correlation of caused MIMO two-way deteriorates and user experience is caused to decline.
As shown in fig. 7, in a specific embodiment of the invention, the realization process of method for transmitting signals can be with are as follows:

With mutual isolation, and by these results send to transmit-receive tube manage unit；
Secondly, the condition according to preset in advance is (pre- based on the first space isolation and second space isolation and isolation
If the matching relationship of value), judge whether antenna deteriorates；
Furthermore in the case where double antenna does not deteriorate, then signal is transmitted using double antenna；And in double antenna
When any antenna deteriorates, the comparison of radiation efficiency and efficiency preset value further according to two antennas determines double antenna
Whether meet MIMO transmission condition, i.e., in the case where meeting MIMO transmission condition, illustrates that only isolation factor leads to MIMO
The correlation of two-way deteriorates, and uses new antenna combination to carry out MIMO transmission after can switching antenna, and is being unsatisfactory for
In the case where MIMO transmission condition, then direct closing problem antenna circuit, switchs to SISO circuit transmissioning signal.
If still meeting MIMO condition, only isolation factor causes MIMO two-way correlation to deteriorate, then can switch day
MIMO transmission is carried out using new antenna combination after line.
In this way, the method for the embodiment of the present invention directly utilizes the protocol data packet of link management in MIMO transmission interval slots
Systematically monitoring aerial state is carried out, data transmission period, and intimate real-time monitoring is not wasted, may make each group of number of WIFI
Can have an opportunity to select suitable transmission mode according to packet, can solve the problem of leading to packet loss because of antenna condition deterioration.
Also, the method for the embodiment of the present invention can't additionally occupy WIFI number using the data packet of the link maintenances such as ACK
According to resource.The method of the embodiment of the present invention can also carry out the state adjustment of antenna for every two data packet, theoretically may be used
To manage nearly all WIFI package, the defect for losing again modified post-processing mechanism in conventional method can also be solved,
It can obtain the message of antenna before each package and do timely to adjust.
