Fig. 2A is the implementation process schematic diagram for the method that the embodiment of the present application eliminates mutual interference, as shown in Figure 2 A, the party
Method includes:
S201, preset uplink frequency sub-band harmony marble frequency range is obtained, any frequency point institute in the uplink frequency sub-band is right
The harmonic frequency answered is different from frequency corresponding to any frequency point in the harmonic wave frequency sub-band；
Here, with no restrictions for the number of preset uplink frequency sub-band harmony marble frequency range, at least one is preset
Uplink frequency sub-band and a preset harmonic wave frequency sub-band, still, harmonic wave corresponding to any frequency point in the uplink frequency sub-band
Frequency (such as second harmonic frequency) is different with frequency corresponding to any frequency point in the harmonic wave frequency sub-band, in this way,
In the side UE, when UE transmits upstream data by the frequency point in uplink frequency sub-band, the transmitting harmonic frequency of the frequency point (such as it is secondary humorous
Wave frequency rate), due in the reception frequency range of the UE (the i.e. described harmonic wave frequency sub-band), UE will not thus not interfered to receive base station
The downlink data transmitted by the harmonic wave frequency sub-band.
S202, the upstream data that UE is sent is received；
Here, it should be noted that for step S201 and S202 sequential relationship with no restrictions, in general, connecing
Before receiving the upstream data that UE is sent, base station has obtained preset uplink frequency sub-band harmony marble frequency range, for example, base station exists
When starting to work after powering on, obtains preset uplink frequency sub-band harmony marble frequency range and be stored in local, be then based on preset
Uplink frequency sub-band harmony marble frequency range carries out the distribution of frequency spectrum resource used in transmitting uplink data and downlink data transmission,
So that the UE for accessing the base station carries out the transmission of upstream data by the frequency point in the uplink frequency sub-band, the base station is utilized
Frequency point in the harmonic wave frequency sub-band carries out the transmission of downlink data, in this way, avoiding under the transmission interference of the side UE upstream data
The reception of row data.
If S203, the upstream data are transmitted by the frequency point in the uplink frequency sub-band, the harmonic wave is utilized
Frequency point in frequency sub-band sends downlink data to the UE.
In the embodiment of the present application, a kind of method for providing elimination mutual interference passes through preset uplink in the method
Frequency point in frequency sub-band transmits upstream data, downlink data is transmitted by the frequency point in preset harmonic wave frequency sub-band, due to described
Frequency corresponding to harmonic frequency corresponding to any frequency point in uplink frequency sub-band and any frequency point in the harmonic wave frequency sub-band
Rate is different, and therefore, when UE sends data using the frequency point in uplink frequency sub-band, the harmonic frequency of the frequency point will not influence UE and connect
The downlink data is received, it is, will not influence the reception of UE downlink data when the transmission of UE upstream data.
In other embodiments, described to obtain preset uplink frequency sub-band harmony marble frequency range for step S201, including
Following steps:
It, will be described if harmonic wave frequency range corresponding to S2011, uplink band to be allocated belongs to band downlink to be allocated
Uplink band is divided, and M uplink frequency sub-band is obtained, and then obtains M harmonic wave corresponding to the M uplink frequency sub-band
Frequency range；
Here, it should be noted that M is the integer more than or equal to 1, and in general, M is equal to 2,3,4,5.But it is theoretical
From, M is the bigger the better because the harmonic wave frequency sub-band obtained in this way is narrower, thus to ready-portioned harmonic wave frequency sub-band into
When row resource allocation, the availability of frequency spectrum of band downlink just can be higher.For example, uplink band be 1710MHz extremely
1785MHz, if the uplink band is averagely divided into two sections, two obtained uplink frequency sub-band be A frequency range and B frequency range, often
The bandwidth of a uplink frequency sub-band is 37.5MHz；Accordingly, the two harmonic wave frequency sub-band obtained be A1 frequency range and B1 frequency range, in order to
The transmission for occurring upstream data in the side UE is avoided to influence mutual interference problem caused by the reception of downlink data, in same base station
In the cell covered, if carrying out the transmission of upstream data using A frequency range, the transmission of downlink data can only use B1
Frequency range cannot use A1 frequency range to carry out the transmission of downlink data；Similarly, if carrying out the transmission of upstream data using B frequency range, that
, the transmission of downlink data can only use A1 frequency range, B1 frequency range cannot be used to carry out the transmission of downlink data.As it can be seen that if
When carrying out frequency range division, the bandwidth of the uplink frequency sub-band of division is narrower, that is, the number M of uplink frequency sub-band bigger, accordingly,
Harmonic wave frequency sub-band is also narrower, in this way, when same cell carries out frequency spectrum resource distribution, it is impossible to be used in transmission downlink data
Harmonic wave frequency sub-band bandwidth it is narrower, to improve frequency efficiency.
In other embodiments, the uplink band belongs to frequency range used in fourth generation mobile communication technology 4G, such as
LTE B3 frequency range, the band downlink belong to frequency range used in the 5th third-generation mobile communication technology 5G, such as NR n78 frequency range.?
When 4G network and 5G NR carry out networking, if LTE B3 frequency range is as the uplink band, NR n78 frequency range is as the downlink
Frequency range, then, in the side UE, when UE sends upstream data using the frequency point of LTE B3 frequency range, as shown in Figure 2 B, LTE B3 frequency range
Transmitting harmonic frequency (such as second harmonic frequency) corresponding to any frequency point of 1710MHz to 1785MHz is exactly in 5G NR
Reception frequency range 3300MHz between 3800MHz, i.e. the second harmonic frequency range of LTE B3 frequency range 1710MHz to 1785MHz and 5G
3420MHz to 3570MHz in the reception frequency range of NR is identical, in this way, if the received downlink data of UE be by 3420MHz extremely
Some frequency point (such as the corresponding frequency of certain frequency point is 3420MHz) transmission, may will lead to UE and utilize in 3570MHz
When frequency point (such as the corresponding frequency of certain frequency point is 1710MHz) in LTE B3 frequency range sends upstream data, in LTE B3 frequency range
The corresponding second harmonic frequency of frequency point (such as the corresponding second harmonic frequency of 1710MHz be 3420MHz) inside will be passed through
4G antenna directly radiates, and is received by 5G antenna, to interfere the receptivity of 5G antenna.
As above analysis is as can be seen that in the example above, and uplink band LTE B3 frequency range 1710MHz to be allocated is extremely
1785MHz, corresponding harmonic wave frequency range 3420MHz to 3570MHz are precisely in band downlink 5G NR frequency range to be allocated
Therefore 3420MHz to 3570MHz can divide LTE B3 frequency range, obtain M uplink frequency sub-band, be inherently derived M
M harmonic wave frequency sub-band corresponding to the uplink frequency sub-band, for example, shown in Fig. 2 C, extremely by LTE B3 frequency range 1710MHz
1785MHz is averagely divided into two sections, i.e., (i.e. (i.e. 1747.5MHz is extremely for 1710MHz to 1747.5MHz) and B frequency range for A frequency range
1785MHz), accordingly, the harmonic wave frequency sub-band obtained is that (i.e. 3420MHz to 3495MHz) and B1 frequency range are (i.e. for A1 frequency range
3495MHz to 3570MHz)；
For another example, shown in Fig. 2 D, LTE B3 frequency range 1710MHz to 1785MHz is averagely divided into four sections, i.e., C frequency range is (i.e.
(i.e. (i.e. 1747.5MHz is extremely for 1728.75MHz to 1747.5MHz), E frequency range for 1710MHz to 1728.75MHz), D frequency range
1765.75MHz), F-band (i.e. 1765.75MHz to 1785MHz), accordingly, obtained harmonic wave frequency sub-band be C1 frequency range (i.e.
(i.e. (i.e. 3495MHz is extremely for 3457.5MHz to 3495MHz), E1 frequency range for 3420MHz to 3457.5MHz), D1 frequency range
3531.5MHz), F1 frequency range (i.e. 3531.5MHz to 3570MHz).Here, it is also possible to carry out the uplink band unequal
Division, that is to say, that for the uplink band division mode with no restrictions.
S2012, at least one uplink frequency sub-band is obtained from the M uplink frequency sub-band, and frequently from M harmonic wave
Duan Zhong, other harmonic wave frequency sub-band in addition to obtaining the harmonic wave frequency sub-band corresponding at least one described uplink frequency sub-band.
For example, M uplink frequency sub-band is A frequency range, B frequency range and corresponding M harmonic wave frequency sub-band A1 in the example above
Frequency range, B1 frequency range, two groups of acquisition include the data of uplink frequency sub-band harmony marble frequency range are as follows: first group includes A frequency range and B1 frequency
Section, second group includes B frequency range and A1 frequency range, this two groups of data are exactly to execute the result of step S2012；For another example, M uplink son frequency
Section be the example above in C frequency range, D frequency range, E frequency range, F-band and corresponding M harmonic wave frequency sub-band C1 frequency range, D1 frequency range,
E1 frequency range, F1 frequency range, four groups of acquisition include the data of uplink frequency sub-band harmony marble frequency range are as follows: first group includes C frequency range, D1 frequency
Section, E1 frequency range, F1 frequency range, second group includes D frequency range, C1 frequency range, E1 frequency range, F1 frequency range, third group include E frequency range, C1 frequency range,
D1 frequency range, F1 frequency range, the 4th group includes F-band, C1 frequency range, D1 frequency range, E1 frequency range, this four groups of data are exactly to execute step
S2012's as a result, certain, however it is not limited to this four groups of data, for example, can also be C frequency range, D frequency range, E1 frequency range, F1 frequency range etc.
Combined data, that is to say, that any frequency in the uplink frequency sub-band harmony marble frequency range of acquisition, in the uplink frequency sub-band
The corresponding harmonic frequency of point is centainly different with frequency corresponding to any frequency point in the harmonic wave frequency sub-band, in this way,
In the cell of base station covering, the transmission of upstream data is carried out using the uplink frequency sub-band of the acquisition, is obtained using described
The harmonic wave frequency sub-band taken carries out the transmission of downlink data, and the side UE can be avoided the transmission interference downlink data of upstream data occur

4G network necessarily will appear the problem of coexisting with the 5G NR form combined, and this 4G network coexists with 5G network
Problem is mainly manifested in the side UE, as shown in Figure 8 A, in transmitting link, if using 4G frequency range (such as LTE B3 frequency range) as uplink
The transmission frequency range of data, in receives link, if using 5G frequency range (such as NR n78 frequency range) as the reception frequency range of downlink data,
So, this coexistence problems are mainly manifested in second harmonic frequency 2f0 (the i.e. hair of the LTE antenna of transmitting chain road of 4G frequency range
Radio frequency rate TX=2f0) it is directly radiated by internal LTE antenna and is received by 5G NR antenna, and the frequency range of 5G NR communication (connects
Receive the reception frequency RX=2f0 of the 5G NR antenna of chain road) it is exactly frequency spectrum where the second harmonic frequency 2f0 of 4G frequency range, from
And influence the receptivity of 5G NR antenna.Currently, the main filter pair for passing through hardware coexists for 4G network and 5G network
The harmonic wave of 4G frequency spectrum is decayed, and to realize coexisting for the two, as shown in Figure 8 B, main thought is exactly in transmission link on
Pass through filter with filter 801 is increased between circuit 802 and match circuit 803 to realize the decaying of harmonic frequency 2f0
801 filter out harmonic frequency 2f0, to reach coexisting for 4G and 5G.
In addition, as shown in Figure 2 B, which show coexisting between typical LTE B3 and NR n78, the wherein harmonic wave of LTE B3
Frequency is exactly within the reception frequency range of 5G NR.Coexistence problems when this works together LTE B3 and NR n78 exist
Great risk.The solution of hardware access mainly realizes harmonic filtration by increasing filter on transmitting chain road, but
It is to have the defects that increase cost.
By carefully analyzing, LTE B3 the transmitting link of UE bandwidth of operation in 1710MHz between 1785MHz, it is right
The total 150MHz of harmonic frequency 3420MHz to 3570MHz answered is within NR n78.If realizing that distribution is cut in data transmission
It changes, then can realize avoiding for harmonic wave in base station side, main thought is exactly to lead to the layout of the layout of the base station 4G and the base station 5G
It crosses algorithm and realizes separation.As shown in Figure 2 C, the thinking of this programme is given, in base station side, LTE B3 frequency range is segmented, is obtained
To A frequency range and B frequency range, natural income to harmonic wave frequency sub-band can also be segmented, A1 frequency range and B1 frequency range are obtained, if by A
Frequency range and the combination of B1 frequency range, combine B frequency range and A1 frequency range, then the intersection that harmonic wave may be implemented avoids interference, it is, by A
The base station 4G is given in frequency allocation, for the transmission of upstream data, gives B1 frequency allocation to the base station 5G, for the transmission of downlink data,
In this way, when UE sends upstream data by A frequency range, the harmonic frequency of A frequency range will not interfere connecing for the signal of B1 frequency range in the side UE
