All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a flowchart illustrating a first embodiment of an interference signal avoidance method according to the present invention. As shown in fig. 1, the interference avoidance method according to the present embodiment is performed by a communication device equipped with an antenna in an operating frequency range (frequency point f) supported by the antenna_minTo frequency point f_max) The antenna beams are radiated at each frequency point, the radiation directions of the antenna beams radiated at different frequency points are different, and the communication equipment can simultaneously communicate with opposite-end equipment in each communication direction through the antenna. At the same time, the communication device only needs to communicate with the opposite-end device in one or more communication directions in the above communication directions, and the device with which other communication devices do not need to communicate causes interference to the opposite-end device with which the communication device needs to communicate; in this embodiment, when the communication device communicates with the peer device that needs to communicate, if the communication device is interfered by other devices, the communication device may control the antenna to perform beam adjustment to avoid the interferenceThe body is as follows:

s101, the communication equipment simultaneously adopts the first effective wave beams in the M communication directions to receive signals.

The first effective beam of any one communication direction is determined by the communication device in a plurality of effective beams included in the first antenna beam group of the communication direction; the communication directions correspond to the first effective wave beams one to one; the first antenna beam group of the communication direction comprises all antenna beams covering the communication direction; any effective beam of a plurality of effective beams included in a first antenna beam group in the communication direction is formed by a plurality of antenna beams with continuous frequency points in the first antenna beam; in a plurality of effective beams included in a first antenna beam group in the communication direction, the bandwidth of any effective beam is equal to the working bandwidth required by the communication direction; the working frequency range of the communication direction is consistent with the frequency range of the first effective wave beam of the communication direction; the M is an integer not less than 2, and the working frequency ranges of any two communication directions in the M communication directions have no intersection;

specifically, fig. 2 is a schematic diagram of an antenna beam according to an embodiment of the present invention. As shown in fig. 2, the Antenna may specifically be a Frequency-scanning Antenna (Frequency-Scanned Antenna), and the Antenna may radiate electromagnetic waves in various directions at various Frequency points within its operating Frequency range, that is, the Antenna may radiate Antenna beams at each Frequency point within its operating Frequency range and in a radiation direction corresponding to each Frequency point, where the radiation directions of the Antenna beams radiated by the Antenna at different Frequency points are different, so that the radiation directions of the Antenna beams with different Frequency points are different; electromagnetic waves radiated by the antenna at a frequency point, that is, antenna beams form a certain shape in a beam irradiation area, for example, light beams emitted to a dark place by a flashlight, one antenna beam necessarily has a certain coverage area, for example, a triangle is used in fig. 2 to represent the antenna beams radiated by the antenna at a frequency point (fig. 2 is a schematic plan view, it can be understood that in practice, the antenna beams are not a planar triangle); in all antenna beams radiated by the antenna, coverage exists to the same communication partyA plurality of antenna beams, so in this embodiment, all antenna beams covering the communication direction constitute a first antenna beam group of the communication direction; e.g. the total antenna beam radiated by the antenna (antenna beam f)_minTo the antenna beam f_max) In the antenna at frequency point (f)_i-BW_maxi/2) to frequency point (f)_i+BW_maxiThe antenna beams radiated at each frequency point in the/2) are superposed to form an overlapping area A, the communication direction i is positioned in the overlapping area A, i represents the mark of the communication direction, f_iIndicating a frequency point with an antenna at frequency f_iThe radiated antenna beam may be denoted as antenna beam f_iIt can also be said that the antenna beam f_iHas a frequency point of f_i，f_min≤f_i≤f_maxAnd the frequency point is less than (f)_i-BW_maxiThe wave beam and frequency point of any antenna of/2) are greater than (f)_i+BW_maxiThe wave beam of any antenna of the/2) can not cover the communication direction i, and the antenna is called to be at the frequency point (f)_i-BW_maxi/2) to frequency point (f)_i+BW_maxi/2) the antenna beam radiated at each frequency point is the first antenna beam group, BW, of the communication direction i_maxiIs a natural number; wherein (f)_i-BW_maxi/2) and (f)_i+BW_maxi/2) is not less than f_minAnd is not greater than f_max(ii) a It can be understood that, of all antenna beams radiated by the antenna, all antenna beams covering any one communication direction form a first antenna beam group of the communication direction; it is also understood that the antenna beam covering the communication direction referred to herein is a corresponding beam such as a 1dB power angle or a 3dB power angle for specifying the antenna covering the communication direction.

Further, when a communication network is deployed, the antenna is at the frequency point (f)_i-BW_maxi/2) to frequency point (f)_i+BW_maxiThe antenna beams radiated at each frequency point in the frequency point (f) cover the communication direction i, and the antenna is arranged at the frequency point (f)_i-BW_maxi/2) to frequency point (f)_i+BW_maxi/2) the antenna beams radiated at the respective frequency points form a first antenna beam group of a communication direction iThe operating frequency range may be in the interval [ (f)_i-BW_maxi/2)，(f_i+BW_maxi/2)]Is equal to a sub-interval of the working bandwidth required by the communication direction i; for example, the operating bandwidth required for the communication direction i is BW, and the interval [ (f)_1+s1-BW/2)，(f_1+s1+BW/2)]Is the interval [ (f)_i-BW_maxi/2)，(f_i+BW_maxi/2)]A sub-interval of (a); so that the antenna is at frequency point (f)_1+s1BW/2) to frequency point (f)_1+s1+ BW/2) the antenna beams radiated at the respective frequency points may constitute an effective beam of the first antenna beam group in the communication direction i, if in the interval [ (f)_2+s2-BW/2)，(f_2+s2+BW/2)]Also in the interval [ (f)_i-BW_maxi/2)，(f_i+BW_maxi/2)]When the antenna is in the frequency point (f)_2+s2BW/2) to frequency point (f)_2+s2The antenna beams radiated at each frequency point in + BW/2) may also form an effective beam in the first antenna beam group in the communication direction i, wherein the frequency range of the effective beam is determined by the frequency point of each antenna beam forming the effective beam; when the communication network is deployed, the working frequency range configured for the communication direction i is an interval [ (f)_1+s1-BW/2)，(f_1+s1+BW/2)]Then, in practical application, the communication equipment controls the antenna to be at the frequency point (f)_1+s1BW/2) to frequency point (f)_1+s1+ BW/2) as the first effective beam of the communication device i, or that the communication device determines that the antenna is at the frequency point (f) among a plurality of effective beams included in the first antenna beam group in the communication direction i_1+s1BW/2) to frequency point (f)_1+s1+ BW/2) is the first effective beam, and thus the working frequency range configured for the communication direction i is frequency (f)_1+s1BW/2) to frequency (f)_1+s1+ BW/2); for convenience of description, the effective beam is represented by a center frequency in a frequency range of the effective beam, and is represented by an antenna beam (f)_1+s1-BW/2) to antenna beam (f)_1+s1+ BW/2) the first active beam may be denoted as active beam f_1+s1。

It should be noted that, the communication device communicates with each peer device through the antenna beam radiated by the antenna, and each peer device is distributed in different communication directions, so that all peer devices in the communication direction that the antenna beam radiated by the antenna can cover can communicate with the communication device; the M communication directions are communication directions in which the communication equipment needs to communicate at the current moment; in the above S101, the communication device simultaneously receives signals using the first effective beams in the M communication directions, where the communication device simultaneously uses the first effective beams in the M communication directions to perform point-to-multipoint communication with each peer device in the M communication directions; one or more opposite devices in one communication direction can be provided; the opposite terminal equipment in each communication direction can adopt any sub-range in the working frequency range of the communication direction in which the opposite terminal equipment is positioned as the respective working frequency range;

it can be understood that the frequency points of antenna radiation antenna beams of the antenna are different according to different radiation directions, and a common coverage area does not necessarily exist between any two antenna beams, that is, an overlapping area does not necessarily exist between any two antenna beams, it is indicated that an upper limit value exists for the bandwidth of an effective beam provided by the antenna for a certain communication direction, where the upper limit value is the maximum bandwidth supported by the antenna in the communication direction, and in order to ensure that the antenna can provide an effective beam with a bandwidth equal to the working bandwidth required by the communication direction to the communication direction, the working bandwidth in the communication direction is not greater than the maximum bandwidth supported by the antenna;

further, the frequency point of the antenna beam changes with the change of the radiation direction, the change rate of the radiation direction of the antenna beam relative to the frequency is expressed by k (f) (unit: degree/Hz), the half-power angle of the antenna is α, and the maximum bandwidth supported by the antenna in the communication direction is BW_maxThen to ensure that the antenna can provide the maximum bandwidth as BW_maxEffective beam of

That is to say

It can also be said that

When the antenna can have a BW requirement toward the working bandwidth_maxWhich provides an effective beam, and α may be differently limited depending on the requirements for antenna performance, which may be defined as a 1dB power angle of the antenna, for example.

Further, in order to ensure that the communications performed in the M communication directions do not interfere with each other, a non-intersection between the operating frequency ranges of any two communication directions in the M communication directions can be achieved, and the value of M should satisfy the condition:

wherein BW_iOperating Bandwidth, BW, required for the communication direction i_totalFor a total bandwidth (f) determined according to the operating frequency range of the antenna_max-f_min＝BW_total) (ii) a It can be understood that, because the operating frequency ranges of any two communication directions in the M communication directions do not intersect with each other, the frequency ranges of any two first effective beams in the M communication directions do not intersect with each other.

S102, the communication equipment detects the received signals, determines each interference signal, and determines at least one first communication direction in M communication directions and the interference signal corresponding to the first communication direction according to each interference signal;

there is an intersection between the frequency range of the interference signal corresponding to the first communication direction and the operating frequency range of the first communication direction.

Fig. 3 is a schematic diagram of a communication device according to an embodiment of the present invention. As shown in fig. 3, the communication device at least includes an antenna 10, a multiplexer 11 (including a set of filters), a transceiver 12, an analog-to-digital conversion (ADC) module 131 and a digital-to-analog conversion (DAC) module 132, a baseband processing unit 14, a signal and interference detection unit 15, and a processor 16, in the above S101, under the control of the processor 16, the antenna 10 can simultaneously pass through the first effective beams in the M communication directions to communicate with the devices opposite to the M communication directionsFor the transmission and reception of the line signals, in this embodiment, the first effective beams in the M communication directions are respectively set as "effective beams f_1+s1Effective beam f_2+s2._M+sM"to illustrate, where s 1-sM are all identifications of frequency points, and M frequency points" f_1+s1、f_2+s2......f_M+sM"neither is greater than f_maxAnd is not less than f_minAnd the above M frequency point "f_1+s1、f_2+s2......f_M+sM"any two frequency points are not equal;

signals received by the antenna 10 are filtered by each filter in the multiplexer 11, and are transmitted to each transceiver 12 through a transmission channel corresponding to each filter, each transceiver 12 transmits the received filtered signals to the analog-to-digital conversion module 131, and the signals processed by the analog-to-digital conversion module 131 are finally transmitted to the baseband processing unit 14; the working frequency ranges of any two communication directions in the M communication directions have no intersection, that is, the working frequency ranges of the opposite-end devices located in different communication directions have no intersection, but the working frequency ranges of the opposite-end devices located in the same communication direction may have an intersection or may have no intersection; for example, if an opposite-end device is arranged in the communication direction i, the working frequency range of the opposite-end device does not intersect with the working frequency ranges of the opposite-end devices in other communication directions; and the communication device performs point-to-point communication in a communication direction i; if a plurality of peer devices are arranged in the communication direction i, in the plurality of peer devices located in the communication direction i, the operating frequency range of any one peer device does not intersect with the operating frequency ranges of peer devices located in other communication directions, but the operating frequency ranges of the plurality of peer devices located in the communication direction i may intersect with each other, or may not intersect with each other, at this time, the communication device performs point-to-multipoint communication in the communication direction i, and the transceiver set for the communication direction i is a point-to-multipoint transceiver.

When the antenna 10 receives the signal, a part of the signal is coupled and fed into the signal and interference detection unit 15, and the signal and interference detection unit 15 can detect an interference signal in the signal received by the antenna 10; the processor 16 determines that there is an interference signal in the received signal according to the detection result of the signal and interference detection unit 15, and it should be noted that when the communication device communicates with the peer device in M communication directions through the first effective beam in M communication directions, the antenna continuously radiates the antenna beam, so that the antenna receives the signal through all the radiated antenna beams in the receiving period, and therefore in S102, among the signals received by the communication device, in addition to the signals transmitted by the peer device that needs to communicate in M communication directions, there are other peer devices that do not need to communicate and other peer devices that do not need to communicate in other communication directions, which are the above interference signals for the peer devices that need to communicate in M communication directions, in each interference signal, some interference signals do not intersect with the working frequency ranges of the M communication directions and can be filtered by a filter, while other interference signals intersect with the working frequency range of at least one communication direction of the M communication directions and cannot be filtered by the filter, and the interference signals having the intersection with the working frequency range of at least one communication direction of the M communication directions can be called interference signals corresponding to a first communication direction, and the first communication direction is the communication direction in which the intersection exists between the working frequency and the frequency range of the interference signals;

s103, the communication equipment controls the antenna to enable the radiation direction of each antenna beam radiated by the antenna to deviate from the same adjustment angle in the same plane along the same direction.

And S104, the communication equipment determines a second effective beam for each communication direction in the M communication directions in the antenna beams with the shifted radiation directions.

A second effective beam of the communication direction is determined among a plurality of effective beams included in a second antenna beam group of the communication direction; the second antenna beam group of the communication direction comprises antenna beams which cover the communication direction and are subjected to all radiation direction shifts; the second antenna beam group in the communication direction comprises a plurality of effective beams, and any effective beam is formed by antenna beams with continuous frequency points and offset radiation directions in the second antenna beam; the bandwidth of any effective beam in a plurality of effective beams included in the second antenna beam group in the communication direction is equal to the working bandwidth required by the communication direction; the frequency range of the second effective wave beam in any one first communication direction is not intersected with the frequency range of the interference signal corresponding to the first communication direction;

for example, fig. 4 is a schematic diagram of an antenna beam before radiation direction shift according to a first embodiment of the present invention; fig. 5 is a schematic diagram of an antenna beam with shifted radiation directions according to an embodiment of the present invention. As shown in fig. 4 and 5, at time T1, the entire antenna beam (antenna beam f) radiated at the antenna_min-antenna beam f_max) In, the antenna beam (f)_i-BW_maxi/2) to the antenna beam (f)_i+BW_maxi/2) both cover the communication direction i, i.e. form a first antenna beam group of the communication direction i, and the antenna beams (f)_i+1-BW_max(i+1)/2) to the antenna beam (f)_i+1+BW_max(i+1)/2) both cover the communication direction (i +1), wherein BW_max(i+1)Is a natural number, frequency point (f)_i+1-BW_max(i+1)/2) and frequency point (f)_i+1+BW_max(i+1)/2) not more than f_maxAnd is not less than f_minAfter S103 is performed, i.e., at time T2, the antenna radiates the entire antenna beam (antenna beam f)_min-antenna beam f_max) So that the radiation direction of the antenna beam (f) is shifted_i-BW_maxi/2) antenna beam (f) shifted to the radiation direction_i+BW_maxi/2) all or part of the antenna beams no longer cover the communication direction i, but the antenna beams (f) with shifted radiation directions_i+1-BW_max(i+1)/2) antenna beam (f) shifted to the radiation direction_i+1+BW_max(i+1)/2) antenna beams (f) whose radiation directions are offset no longer cover the communication direction (i +1) but do not cover all or part of the antenna beams_i+1-BW_max(i+1)/2) antenna beam (f) shifted to the radiation direction_i+1+BW_max(i+1)/2) all coverThe second antenna beam group in the communication direction i is the antenna beam (f) shifted from the radiation direction_i+1-BW_max(i+1)/2) antenna beam (f) shifted to the radiation direction_i+1+BW_max(i+1)/2) forming; similarly, the antenna beam group of other communication directions is changed from the first antenna beam group to the second antenna beam group;

due to the replacement of the antenna beam group of the M communication directions, the effective beam for communication is updated, that is, at time T2, the effective beam provided by the antenna for communication direction 1 is no longer the effective beam f_1+s1But the effective beam f_1+r1I.e. the second effective beam provided by the antenna for the communication direction 1 is the effective beam f_1+r1(ii) a Likewise, the effective beam provided by the antenna for the communication direction 2 is no longer the effective beam f_2+s2But the effective beam f_2+r2I.e. the second effective beam provided by the antenna for the communication direction 2 is the effective beam f_2+r2By analogy, at time T2 the effective beam provided by the antenna for communication direction M is no longer the effective beam f_M+sMBut the effective beam f_M+rMI.e. the second effective beam provided by the antenna for the communication direction M is the effective beam f_M+rM. Wherein r 1-rM are the identification of frequency points, and M frequency points' f_1+r1、f_2+r2、......、f_M+rM"neither is greater than f_maxAnd is not less than f_minAnd the above M frequency point "f_1+r1、f_2+r2、......、f_M+rMAnd any two frequency points in the sequence are not equal.

In addition, the first and second antenna beam groups, the second antenna beam group, the first effective beam and the second effective beam are all relative concepts, and for the antenna beam before the radiation direction is deviated, and the second is that for the antenna beams with shifted radiation directions, for example, all antenna beams covering communication direction i at time T1 form the first antenna beam group of communication direction i, and the communication device determines one effective beam among the plurality of effective beams included in the first antenna beam group in the communication direction i as a first effective beam, and the communication device performs S103 at time T2, the antenna beam after the total radiation direction shift covering the communication direction i forms the second antenna beam group of the communication direction i at time T2, one effective beam determined from a plurality of effective beams included in the second antenna beam group in the communication direction i is a second effective beam; if the communication device has performed S103 again at time T3, the aforementioned second antenna beam group and second effective beam of the communication device at time T2 are the first antenna beam group and first effective beam for time T3, and at time T3, the antenna beams shifted in all radiation directions covering the communication direction i form the second antenna beam group for time T2, and the second effective beam for time T2 is determined.

As there is no intersection between the frequency range of the second effective beam in the first communication direction and the frequency range of the interference signal corresponding to the first communication direction; therefore, when the communication device receives the signal in the first communication direction by using the second effective beam provided for the first communication direction, the interference signal corresponding to the first communication direction does not interfere the communication device to receive the signal in the first communication direction; compared with the prior art, the embodiment does not need to adjust the position of opposite-end equipment in each communication direction, interference signals can be avoided by adjusting the effective wave beam of one communication device, and all antenna wave beams of the antenna are uniformly adjusted when the effective wave beam is adjusted, so that the condition that the antenna wave beam in one communication direction is adjusted to influence the communication in other communication directions is avoided, and the optimized interference avoiding process can solve the interference problem in a communication network with higher efficiency.

Fig. 6 is a flowchart illustrating a second method for avoiding an interference signal according to an embodiment of the present invention. As shown in fig. 5, the present embodiment includes:

s201, the communication device receives signals from M communication directions by using M effective beams simultaneously.

S202, the communication equipment detects the received signals and determines the frequency range of each interference signal.

S203, the communication equipment determines each interfered communication direction and an interference signal corresponding to each interfered communication direction in the M communication directions according to the frequency range of each interference signal and the working frequency range of each communication direction.

The working frequency range of the interfered communication direction and the frequency range of the interference signal corresponding to the interfered communication direction have intersection;

for example, when the first antenna beam group of the communication direction i includes antenna beams from frequency point 64.0GHz to frequency point 68GHz, the frequency range of the interference signal Xi is 63.0GHz to 65.0GHz, and the operating frequency range of the communication direction i is 64.0GHz to 64.5GHz, then the communication direction i is the interfered communication direction, but the operating bandwidth required by the communication direction i is 0.5GHz, and the communication direction i can replace the operating frequency ranges from 66.0GHz to 66.5GHz, 66.5GHz to 67.0GHz, and the like, so that when the communication device receives the signal of the communication direction i, the communication device is not interfered by the interference signal Xi, that is, when the communication device knows that there is an intersection between the frequency range of the interference signal Xi and the operating frequency range of the communication direction i, but there is an effective beam without intersection between the frequency range and the frequency range of the interference signal Xi among the effective beams included in the first antenna beam group of the communication direction i, determining that the interference signal Xi can be avoided, and only replacing the working frequency range of the communication direction i; however, if the first antenna beam group in the communication direction i includes antenna beams from the frequency point 64.0GHz to the frequency point 65GHz, and the operating bandwidth required by the communication direction i is 1GHz, that is, if there is no effective beam whose frequency range does not intersect with the frequency range of the interference signal Xi among the effective beams included in the first antenna beam group in the communication direction i, that is, there is no effective beam for replacement, it is determined that the communication direction i is the first communication direction, that is, the following S204 is executed.

S204, for each interfered communication direction, if it is determined that there is no effective beam for replacement in each effective beam included in the first antenna beam group of the interfered communication direction, the communication device determines that the interfered communication direction is the first communication direction, and determines that an interference signal corresponding to the interfered communication direction is an interference signal corresponding to the first communication direction.

S203 and S204 are optional steps, and in order to reduce the detection power consumption of the communication device, when it is determined that the operating frequency range of the communication direction i intersects with the frequency range of the interference signal Xi, it may be determined that the communication direction i is the first communication direction, and the interference signal Xi is the interference signal corresponding to the first communication direction, at this time, although an effective beam for replacement exists in the first antenna beam group of the communication direction i, that is, when the frequency range of the interference signal Xi is 63.0 GHz-65.0 GHz, the operating frequency range of the communication direction i is 64.0 GHz-64.5 GHz, and an effective beam with a frequency range of 66.0 GHz-66.5 GHz, 66.5 GHz-67.0 GHz, and the like can be provided in the first antenna beam group of the communication direction i, the present embodiment implements the following steps, and still can achieve the avoidance of the interference signal Xi, that is to employ the radiation direction of shifting each antenna beam for the interference signal Xi, and avoiding interference signals is realized.

S205, the communication device determines undetermined frequency adjustment values of the first communication directions according to the antenna beam of the maximum frequency point or the antenna beam of the minimum frequency point in the first antenna beam group of each first communication direction and the frequency range of the interference signal corresponding to each first communication direction.

specifically, the frequency range of the interference signal Xi is 63.0GHz to 65.0GHz, the first antenna beam group in the communication direction i includes antenna beams from the frequency point 64.0GHz to the frequency point 65.0GHz, and the working bandwidth required by the communication direction i is 1GHz, that is, there is no effective beam without intersection between the frequency range and the frequency range of the interference signal Xi among the effective beams included in the first antenna beam group in the communication direction i, so that the radiation direction of each antenna beam needs to be shifted to cover a new group of antenna beams to the communication direction i, and the new group of antenna beams can provide effective beams without intersection between the frequency range and the frequency range of the interference signal Xi to the communication direction i; before a new set of antenna beams, which may provide a valid beam with no intersection between the frequency range and the frequency range of the interference signal Xi to the communication direction i, is allowed to cover the communication direction i, it needs to be determined which antenna beams the new set of antenna beams is composed of, in a specific way as follows:

according to

Or according to

Determination of Δ f_iA value range of (1), wherein

The minimum frequency point in the frequency range of the corresponding interference signal Xi when the communication direction i is taken as the first communication direction; f. of_i ^minThe minimum frequency point in the frequency points of each antenna beam in the first antenna beam group in the communication direction i;

the maximum frequency point in the frequency range of the corresponding interference signal Xi when the communication direction i is taken as the first communication direction; f. of_i ^minThe maximum frequency point is the maximum frequency point in the frequency points of each antenna beam in the first antenna beam group in the communication direction i; preferably, in order to reduce the adjustment power consumption

Determination of Δ f_iAfter the value range of (2), usually make Δ f_iIs given by Δ f_iThe maximum value in the value range of (a); in accordance with

Determination of Δ f_iAfter the value range of (A) is reached,usually let Δ f_iIs given by Δ f_iThe minimum value in the value range of (a);

further, at least one first communication direction determined in S204 is used, and for each first communication direction, the same method as that used in the communication direction i is used to determine a respective undetermined frequency adjustment value;

s206, the communication equipment determines the maximum undetermined frequency adjustment value as the frequency adjustment value in the undetermined frequency adjustment values in the first communication directions.

S205 is executed and then S206 is executed in order to allow for each first communication direction.

S207, the communication equipment determines the adjusting angle according to k (f) and the frequency adjusting value;

and S208, the communication equipment control antenna informs each opposite terminal equipment in the M communication directions of the frequency adjustment value through the M first effective wave beams.

Taking communication direction 1 as an example, the first effective beam f of communication direction 1_1+s1Is in the range of 60.0GHz to 60.5GHz, the processor of the communication device passes the effective beam f before executing S209 below_1+s1Communicating with opposite-end equipment in the communication direction 1, wherein the working frequency range of the opposite-end equipment A in the communication direction 1 is 60.0 GHz-60.25 GHz, and the working frequency range of the opposite-end equipment B is 60.15 GHz-60.5 GHz; after the communication device determines that the frequency adjustment value Δ f is-0.5 GHz according to the above S208, the processor of the communication device needs to make a new group of antenna beams cover the communication direction 1, and further, the operating frequency of a new effective beam provided for the communication direction 1 is 59.5 GHz-60.0 GHz, and correspondingly, in order to make the peer device in the communication direction 1 communicate with the communication device through the new effective beam, the respective operating frequency ranges also need to be adjusted, that is, the operating frequency range of the peer device a is correspondingly changed to 59.5 GHz-59.75 GHz, and the operating frequency range of the peer device a is correspondingly changed to 59.65 GHz-60.0 GHz; so that the effective beam f passes before S209 is performed_1+s1Informing the opposite terminal device in the communication direction 1 that the frequency adjustment value delta f is-0.5 GHz, so that the working frequency of the new effective beam provided for the communication direction 1 is 59.5GHz EAfter 60.0GHz, each peer device in the communication direction 1 and the communication device of this embodiment may use a new effective beam to continue communication;

s208 is described above by taking the communication direction 1 as an example, and S208 is implemented similarly to the communication direction 1 for each of the other communication directions.

Naturally, optionally, the communication device may not perform S208, for example, after determining the frequency adjustment value, report (in a wired communication manner) the frequency adjustment value to a management device of the communication network, and the management device of the communication network notifies each peer device in the M communication directions of the frequency adjustment value.

And S209, the communication equipment controls the antenna to shift the radiation direction of each radiated antenna beam by the same adjustment angle along the same direction.

S210, the communication equipment determines a second effective beam for each communication direction in the M communication directions in the antenna beams with all the shifted radiation directions.

By performing S209, the first effective beam (effective beam f) of the M communication directions_1+s1To the effective beam f_M+sM) Is replaced with a second effective beam (effective beam f)_1+r1To the effective beam f_M+rM)。

S211, the communication device updates each first filter of each transceiver in the communication device to each second filter.

Each of the first filters is matched with each of the first effective beams, and each of the second filters is matched with each of the second effective beams;

taking the communication device shown in fig. 3 as an example, before performing S210, the communication device provides M first effective beams for M communication directions, and accordingly, in the filter bank in the multiplexer 11, the filter matched with the first effective beam is the first filter; specifically, the filtering range of the first filter is matched with the frequency range of the first effective beam;

since the effective beams provided by the antenna for the M communication directions change, and accordingly, the filtering ranges of the filters for filtering the signals also need to be adjusted, so that the transceivers of the communication device can successfully acquire or transmit the signals, after S210 is executed, the filter matched with the first effective beam in the filter bank in the multiplexer 11 is replaced with the filter matched with the second effective beam, that is, the first filter is updated to the second filter; the filtering range of the second filter is matched with the frequency range of the second effective beam; optionally, the communication device may update each first transmission channel allocated to each transceiver to each second transmission channel, so as to implement updating of the filter;

each of the first transmission channels is for connection to a respective first filter and a respective transceiver; each of the second transmission channels is used for connecting each of the second filters and each of the transceivers;

fig. 7 is a schematic diagram of a channel allocation unit in the communication device shown in fig. 3. As shown in fig. 7, the channel allocating unit 17 in fig. 3 is specifically a switch array, and establishes a transmission channel C between each transceiver and each filter by closing or opening each switch in the switch array; fig. 7 in this embodiment is exemplified by the state of the switch array at the time T1, since at the time T1, the M first effective beams provided by the antenna for the M communication directions are respectively effective beams f_1+s1To the effective beam f_M+sMEach transceiver is assigned an active beam f by closing or opening each switch in the switch array_1+s1To the effective beam f_M+sMEach first filter being matched for use with the effective beam f_1+s1To the effective beam f_M+sMThe transmission channels of the matched first filters connected to the transceivers are called first transmission channels, and when at time T2, the M second effective beams provided by the antenna for the M communication directions are respectively effective beams f_1+r1To the effective beam f_M+rMThen used for the active beam f_1+r1To the effective beam f_M+rMThe respective transmission channel on which the matched respective second filter and the respective transceiver are connected is called the respective second transmission channel, in particular, whether the first active beam or the second active waveBeams, each filter being matched to an effective beam when the filters are matched to the effective beams determined by the processor for the respective communication direction, or both filters being matched to an effective beam, e.g. by the effective beam f_1+s1The received signal may be formed by a sum of one and the effective beams f_1+s1The matched filter filters out completely, but passes through the effective beam f_M+sMThe received signal needs to be composed of two effective beams f_M+sMThe matched filters are matched to completely filter out;

or, optionally, when performing S211, specifically, the communication device updates each first filter constructed for each transceiver to each second filter.

For example, fig. 8 is a schematic diagram of a communication device according to a second embodiment of the present invention. As shown in fig. 8, the multiplexer 11 in fig. 8 is a logic device or a digital chip, and may simulate filters corresponding to different frequency ranges under the control of the processor 16, and the transceiver 12, the analog-to-digital conversion module 131 and the digital-to-analog conversion module 132 are disposed between the antenna 10 and the multiplexer 11; or alternatively, when the multiplexer 11 is an analog device, the multiplexer 11 may also be disposed after the transceiver 12 and before the analog-to-digital conversion module 131 and the digital-to-analog conversion module 132; at time T1, antenna 10 provides M first effective beams for M communication directions, and accordingly, processor 16 controls multiplexer 11 to construct respective first filters matched to the M first effective beams at time T1, and subsequently at time T2, antenna 10 provides M second effective beams for M communication directions, and accordingly, processor 16 controls multiplexer 11 to construct respective second filters matched to the M second effective beams at time T2;

it is to be understood that the above-mentioned transceiver may be used only for the function of a receiver, or only for the function of a transmitter, and when the transceiver is used only for the function of a receiver, the transceiver is a receiver, and when the transceiver is used only for the function of a transmitter, the transceiver is a transmitter; according to the actual communication requirement, each receiver and each transmitter can be separately arranged in the communication equipment; for example, fig. 9 is a schematic diagram of another communication device in the second embodiment of the present invention. As shown in fig. 9, the communication device includes two sets of working systems, one set of working system is used for transmitting signals, and the other set of working system is used for receiving signals; in the communication device shown in fig. 9, the transceiver 12 in the communication device shown in fig. 3 or fig. 8 is divided into the receiver 121 and the transmitter 122, so that each receiver 121, the antenna 10, the multiplexer 11, the channel allocating unit 17, and the analog-to-digital converter 131 form an operating system S1 for receiving signals, and each transmitter 122, the antenna 10, the multiplexer 11, the channel allocating unit 17, and the digital-to-analog converter 132 form an operating system S2 for transmitting signals; and the signal and interference detecting unit 14 is connected with the antenna 10 in the operating system S1;

since the communication device communicates with the counterpart devices located in M communication directions, all antenna beams radiated by the antenna 10 in the operating system S1 are used for receiving signals from each communication direction, and all antenna beams radiated by the antenna 10 in the operating system S2 are used for transmitting signals to each communication direction; all effective beams supported by the antenna 10 in the working system S1, each effective beam provided by the antenna for M communication directions and each effective beam (the first effective beam or the second effective beam) provided by the antenna 10 in the working system S2 for M communication directions have to be in one-to-one correspondence, two corresponding effective beams are regarded as a beam pair, two effective beams in one beam pair are both directed to the same communication direction, and bandwidths of the two effective beams are the same and Frequency ranges may be the same or different, which is one possibility that, when the communication device shown in fig. 9 is applied in an FDD (Frequency Division duplex) communication mode, the communication device communicates with the communication direction i, and the antenna 10 in the working system S1 provides the first effective beam f to the communication direction i_iAntenna 10 in operating system S2 also provides a first active beam f 'for communication direction i'_iFirst effective beam f_iAnd a first active beam f'_iHas the same beam direction and the same bandwidth but different frequency range, and a first effective beam f_iWith the first active beam f'_iThe frequency range being FDD communication partnerWherein, a group of corresponding uplink and downlink communication frequency ranges; more specifically, at the aforementioned time T1, for the operating system S1, the communication device controls the antenna 10 of the operating system S1 to provide M first effective beams for M communication directions as the effective beam f_1+s1To the effective beam f_M+sMCorrespondingly, for the operating system S2, the antenna 10 of the communication device control operating system S2 provides M first active beams of f 'for M communication directions'_1+s1To effective beam f'_M+sM(ii) a Active beam f for receiving signals provided by antenna 10 in operating system S1_1+s1Is 57.5GHz to 58.0GHz, then correspondingly, the effective wave beam f 'for transmitting signals provided by the antenna in the working system S2'_1+s1The frequency range of (57.5+3.0) GHz to (58.0+3.0) GHz; and the antenna 10 in the operating system S1 provides the effective beam f for receiving signals_M+sMIs in the range of 59.0GHz to 59.5GHz, corresponding to the active beam f 'provided by the antenna 10 in the operating system S2 for transmitting signals'_M+sMThe frequency range of (2) is (59.0+3) GHz to (59.5+3) GHz;

when the processor of the communication device executes the aforementioned S208 to S211, it is executed simultaneously for the operating system S1 and the operating system S2, i.e. the effective beam f that the antenna 10 in the operating system S1 will provide for the M communication directions is controlled_1+s1To the effective beam f_M+sMModified to the effective beam f_1+r1To the effective beam f_M+rMAt the same time, the antenna 10 in the operating system S2 is controlled to emit an active beam f'_1+s1To effective beam f'_1+sMIs changed into an effective wave beam f'_1+r1To effective beam f'_M+rM(ii) a Then, the filters of the respective receivers are updated and the respective filters of the transmitter are also updated through S211.

Another possibility is that when the communication device shown in fig. 9 is applied in other communication modes such as TDD, full duplex, etc., and when the communication device communicates with the communication direction i, the antenna 10 in the operating system S1 provides the effective beam f to the communication direction i_iAntenna 10 in operating system S2 also provides an active beam f 'for communication direction i'_iEffective beam f_iAnd active beam f'_iHas the same beam direction, the same bandwidth and the same frequency range, and more specifically, at the time T1, for the operating system S1, the communication device controls the antenna 10 of the operating system S1 to provide M first effective beams as the effective beam f for M communication directions_1+s1To the effective beam f_M+sMCorrespondingly, for the operating system S2, the antenna 10 of the communication device control operating system S2 provides M first active beams of f 'for M communication directions'_1+s1To effective beam f'_M+sMAnd the effective beam f_1+s1And active beam f'_1+s1Identical, effective beam f_1+s2And active beam f'_1+s2Identical, and so on, the effective beam f_M+sMAnd active beam f'_M+sMAre completely the same; when the processor of the communication device executes the aforementioned S208 to S211, the antenna 10 in the control operating system S1 will provide effective beams f for M communication directions_1+s1To the effective beam f_M+sMModified to the effective beam f_1+r1To the effective beam f_M+rM(ii) a At the same time, the antenna 10 in the operating system S2 is controlled to emit an active beam f'_1+s1To effective beam f'_M+sMIs changed into an effective wave beam f'_1+r1To effective beam f'_M+rMWherein the effective beam f_1+r1And active beam f'_1+r1Identical, effective beam f_1+r2And active beam f'_1+r2Identical, and so on, the effective beam f_M+rMAnd active beam f'_M+rMAre completely the same; then, the filters of the respective receivers are updated and the respective filters of the transmitter are also updated through S211.

Optionally, the following S212 may also be performed:

s212, the communication device updates the first operating frequency of each transceiver to the second operating frequency.

The first operating frequency is matched with each of the first effective beams, and each of the second operating frequencies is matched with each of the second effective beams.

It should be noted that the above data for representing each frequency range and angle is only used as an example, and can be adjusted according to actual needs, and the data is not limited to the above data.

Compared with the prior art, the embodiment can avoid interference signals by adjusting the effective beam of one communication device without adjusting the position of opposite-end equipment in each communication direction, and uniformly adjusts all effective beams of the antenna when adjusting the effective beam, thereby avoiding the condition that the effective beam in one communication direction is adjusted to influence the communication in other communication directions, optimizing the process of avoiding interference, and solving the interference problem in a communication network with higher efficiency.
