Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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.
Referring to fig. 1, fig. 1 is a flowchart illustrating a communication control method according to an embodiment of the present invention, which is applied to a terminal having multiple antennas, and as shown in fig. 1, the method includes the following steps:
It should be noted that, when the terminal is in the dual connectivity mechanism, the network side device may allocate two frequency bands in different network systems to the terminal, and the terminal may perform data transmission in the two frequency bands, for example, in the dual connectivity mechanism shown in fig. 2, the fourth generation mobile communication network (4G) and the fifth generation mobile communication network (5G) adopt non-independent architectures, and the terminal may perform data transmission in the 4G frequency band and the 5G frequency band.
In step 101, the terminal may initiate network registration when being powered on, the network side device of the dual connectivity mechanism may allocate the first frequency band and the second frequency band for the terminal, the network side device may record the first frequency band and the second frequency band of the data transmitted by the network side device, and the terminal may determine the first frequency band and the second frequency band in which the terminal operates when detecting whether there is signal interference.
In this embodiment, the first frequency band and the second frequency band are frequency bands of different network systems, and the first frequency band is smaller than the second frequency band, for example, in a network architecture as shown in fig. 2, a terminal may perform data transmission on a 4G frequency band and a 5G frequency band, where the first frequency band is the 4G frequency band and the second frequency band is the 5G frequency band.
In step 102, in the case that the terminal determines the first frequency band and the second frequency band in which the terminal operates, the terminal may determine whether signal interference is generated in the first frequency band and the second frequency band based on the first frequency band and the second frequency band.
In this embodiment, the terminal determines whether signal interference exists in the first frequency band and the second frequency band, which may be that the terminal acquires a first channel of the first frequency band and a second channel of the second frequency band, and determines whether signal interference exists between the first frequency band and the second frequency band according to a center frequency point where the first channel is currently located and a center frequency point where the second channel is currently located.
Wherein, the above-mentioned determining whether there is signal interference between the first frequency band and the second frequency band may be determining whether there is frequency multiplication interference between the first frequency band and the second frequency band, that is, whether n times of the transmission bandwidth of the first frequency band falls within the reception bandwidth of the second frequency band, where n is a positive integer, specifically, if the transmission center frequency point of the first channel is f1 and the reception center frequency point of the second channel is f2, comparing m times of the second frequency range [ f1-b4/2, f1+ b4/2] (i.e., m × [ f1-b 1/2, f1+ b1/2]) with the second frequency range [ f 2-b 2/2, f2+ b2/2], and determining that there is signal interference between the first frequency band and the second frequency band if the first frequency range falls into the second frequency range, where b1 is a preset bandwidth of the first frequency band, and b2 is a preset bandwidth of the second frequency band, and m is an integer greater than 1.
Exemplarily, it is assumed that the first frequency band is a 4G LTE B3 frequency band, the first channel is a 19575 channel, the transmission center frequency point f1 is 1747.5MHz, and the bandwidth B1 of the first channel is 10 MHz; the first frequency band is 5G n78, the second channel is 633000, the receiving center frequency f2 is 3495MHz, the bandwidth b2 of the second channel is 20MHz, the frequency range of the second harmonic wave transmitted by the first frequency band is 2 × [1747.5-5,1747.5+5] ([ 3485,3505] (i.e. the first frequency range), the frequency range received by the second frequency band is [ 3495-.
Of course, the terminal determines whether there is signal interference in the first frequency band and the second frequency band, or the terminal determines whether there is intermodulation interference in the first frequency band and the second frequency band, specifically, it may determine whether a sum/difference between k times of a transmission center frequency of the first frequency band and n times of a transmission center frequency of the second frequency band falls within a reception bandwidth of the first frequency band or the second frequency band, where k and n are positive integers.
For example, if the first frequency band is a 4G LTE B1 frequency band, the second frequency band is a 5G n78 frequency band, and the transmission center frequency point of the 4G LTE B1 frequency band is 1950MHz, and the transmission center frequency point of the n78 frequency band is 3710MHz, then the difference between the transmission signal frequency of the B1 frequency band which is 3 times (i.e., k is 3) and the transmission signal frequency of the n78 frequency band (i.e., n is 1) is 2140MHz, and the reception bandwidth of the 4G LTE B1 frequency band is [2110,2170], and the difference falls within the reception bandwidth of the B1 frequency band, so the terminal determines that there is intermodulation interference, i.e., there is signal interference between the first frequency band and the second frequency band, and so on.
In addition, the terminal determines whether signal interference is generated in the first frequency band and the second frequency band, which may be whether signal interference exists in any scene.
In some embodiments, the step 102 may include: determining whether an interference adjustment condition is met between the first frequency band and the second frequency band based on at least one of a network type, a transmitting power and a working time slot of the first frequency band and the second frequency band; and under the condition that an interference adjustment condition is met between the first frequency band and the second frequency band is determined, determining whether the terminal has signal interference or not based on the first frequency band and the second frequency band.
Here, the terminal may determine whether to perform an operation of determining whether there is signal interference in the first frequency band and the second frequency band based on at least one of the network system type, the transmission power, and the working time slot of the first frequency band and the second frequency band, so that the utilization rate of resources of the terminal may be improved.
For example, assuming that the first frequency band is a 4G LTE frequency band and the second frequency band is a 5G NR frequency band, the terminal may determine whether to perform the step 102 under the following scenarios from the first scenario to the sixth scenario, which is as follows:
scene one, a network type of a 4G LTE Frequency band is Frequency Division Duplex (FDD) or Time Division Duplex (TDD), and a network type of a 5G NR Frequency band is FDD, and when a terminal operates in a transmission state of the 4G FDD or the 4G TDD and a transmission power of the 4G LTE Frequency band is greater than a preset power P1, the terminal performs judgment on whether harmonic interference exists, where P1 is a preset power threshold;
in a second scenario, the network type types of the 4G LTE frequency band and the 5G NR frequency band are both FDD, and when the terminal works in a 4G FDD transmitting state and a 5G FDD transmitting state, and the transmitting power of the 4G FDD is greater than the P1, and the transmitting power of the 5G FDD is greater than P2, the terminal performs judgment on whether intermodulation interference exists, wherein P2 is a preset power threshold;
scene three, the network type of the 4G LTE frequency band is TDD, the network type of the 5G NR frequency band is FDD, the 4G TDD is intermittently operated in time slots, and when the terminal is in the transmitting time slot of the 4G LTE frequency band and the transmitting power of the 4G TDD is greater than P1, the terminal judges whether harmonic interference exists;
in a fourth scenario, when the network type of the 4G LTE frequency band is TDD, the network type of the 5G NR frequency band is FDD, the 4G TDD intermittently operates in time slots, and when the terminal is in the transmitting time slot of the 4G TDD, the transmitting power of the 4G TDD is greater than P1, and the transmitting power of the 5G FDD is greater than P2, the terminal performs judgment on whether intermodulation interference exists or not;
the network system types of a scene five, a 4G LTE frequency band and a 5G NR frequency band are TDD, the 4G TDD and the 5G TDD share the time slots to work intermittently, and when the transmitting time slot of the 4G TDD and the 5G receiving time slot are overlapped and the transmitting power of the 4G TDD is greater than P1, the terminal judges whether harmonic interference exists or not;
in the sixth scenario, the network type of the 4G LTE band is FDD or TDD, and the network type of the 5G NR band is TDD, and the terminal does not perform step 102 because the terminal does not operate in the transmitting state and the receiving state of the 5G at the same time.
sending a target message to a network side device, wherein the target message is used for: instructing the network side device to adjust the target communication parameters of the first frequency band and/or the second frequency band according to the target message;
and adjusting the modulation mode of a target antenna in the plurality of antennas.
In step 103, after the terminal determines that there is signal interference between the first frequency band and the second frequency band, the terminal may send a target message to the network side device, and the network side device receives the target message and adjusts the target communication parameters of the first frequency band and/or the second frequency band in response to the target message; or, the terminal may further adjust a modulation mode of a target antenna among the multiple antennas; or, the terminal may also send the target message and adjust the modulation mode of the target antenna at the same time, so as to reduce the signal interference between the first frequency band and the second frequency band of the terminal, thereby improving the communication quality.
The target message may be any message that can achieve the purpose of instructing the network side device to adjust the target communication parameter of the first frequency band so as to reduce the signal interference of the terminal, and specifically, the target communication parameter may be a transmission bandwidth, that is, in a case where the network side device receives the target message, the network side device reduces the transmission bandwidth of at least one of the first frequency band and the second frequency band in response to the target message, so as to achieve the purpose of reducing the interference signal between the first frequency band and the second frequency band.
It should be noted that, the reducing, by the network-side device, the transmission bandwidth of at least one of the first frequency band and the second frequency band may be to reduce a preset transmission bandwidth of the transmission bandwidth of at least one of the first frequency band and the second frequency band, for example, different preset transmission bandwidths may be preset in the network-side device, and in a case that the network-side device receives the target message, the network-side device compares the current transmission bandwidth with each preset transmission bandwidth, and adjusts the transmission bandwidth of at least one of the first frequency band and the second frequency band to be closest to the current transmission bandwidth and lower than the preset transmission bandwidth of the current transmission bandwidth.
In some embodiments, before sending the target message to the network side device, the method may further include:
obtaining the interference amplitude of the interference signal;
the sending the target message to the network side device includes:
sending the target message carrying the interference amplitude to a network side device, wherein the target message is further used for: and instructing the network side equipment to adjust the target communication parameters according to the interference amplitude.
Here, the terminal sends the target message carrying the interference amplitude to the network side device, and the network side device may adjust the target communication parameter according to the interference amplitude carried by the target message in response to the target message when receiving the target message, so that the network side device may adjust the target communication parameter of at least one of the first frequency band and the second frequency band to an appropriate parameter value, and further reduce signal interference between the first frequency band and the second frequency band.
In this embodiment, after receiving the target message carrying the interference amplitude, the network side device may determine a target parameter value associated with the interference amplitude carried by the target message, and adjust a parameter value of a target communication parameter of at least one of the first frequency band and the second frequency band to the target parameter value, and specifically, the adjusting, by the network side device, the target communication parameter of at least one of the first frequency band and the second frequency band may include: reducing at least one of a transmission bandwidth of the first frequency band and a transmission bandwidth of the second frequency band.
The network side device determines a target parameter value associated with the interference amplitude carried by the target message, which may be an association relationship preset between each interference amplitude and a parameter value in the network side device, and determines, according to the association relationship between each preset interference amplitude and a parameter value, a parameter value associated with the interference amplitude carried by the target message as the target parameter value.
Or, a plurality of preset interference amplitudes may be set in the network side device, and the plurality of preset interference amplitudes form a plurality of continuous interference amplitude ranges, and the network side device may compare the interference amplitude carried by the target message with the plurality of preset interference amplitudes, determine a target interference amplitude range in which the interference amplitude carried by the target message is located, and further determine a first adjustment number corresponding to the target interference amplitude range, where the first adjustment number is a number of times for step-by-step adjustment of the target communication parameter.
For example, since the transmission bandwidth or modulation scheme supportable by the network under different network systems is fixed and limited, for example, the transmission bandwidth of 4G LTE generally includes 1.4M, 3M, 5M, 10M, 20M, carrier aggregation, etc., and the transmission bandwidth of 5G NR includes 5M, 10M, 15M, 20M, 25M, 30M, 40M, 50M, 60M, 80M, 90M, 100M, carrier aggregation, etc.;
assuming that the interference amplitude carried by the target message is N, and the multiple preset interference amplitudes set in the network-side device include N1, N2, N3, and … …, and N1< N2< N3 … …, where:
when N < N1, the interference amplitude is small and can not be adjusted;
when the target communication parameter is a transmission bandwidth and the current transmission bandwidth of the first frequency band is 20M, when N1< N2, interference exists, and the network side device may reduce the transmission bandwidth of the first frequency band by 1 step, that is, reduce the transmission bandwidth of the first frequency band to 15M; when N2< N3, there is interference, and the network side device may reduce the transmission bandwidth of the first frequency band by 2 steps, that is, reduce the transmission bandwidth of the first frequency band to 5M, and so on … …;
in addition, the above-mentioned terminal may acquire the interference amplitude of the interference signal, where the terminal sets a Noise Profiling Tool (NPT) with a self-scanning function, that is, in a case of no external network, the terminal drives its radio frequency system to perform self-detection of the radio frequency signal, and automatically records the interference amplitude of the terminal, or may acquire the interference amplitude of the interference signal in other manners, which is not limited herein.
In this embodiment, when it is determined that signal interference exists between the first frequency band and the second frequency band, the terminal may further adjust a modulation mode of a target antenna in the multiple antennas, so as to reduce the signal interference between the first frequency band and the second frequency band.
The target antenna is at least one of multiple antennas of the terminal, and may be, for example, one antenna randomly determined among the multiple antennas, or one antenna determined among the multiple antennas according to a preset rule, and specifically, since interference is strongly correlated with transmission, a receiving antenna close to an uplink (i.e., TX) may be determined as the target antenna.
In some embodiments, the adjusting the modulation scheme of the target antenna of the multiple antennas includes:
acquiring interference parameters of the plurality of antennas;
determining a target antenna among the plurality of antennas based on the interference parameters of the plurality of antennas;
and adjusting the modulation mode of the target antenna.
Here, the terminal may determine the target antenna according to the interference parameters of the multiple antennas, so that the determined target antenna is more suitable, and the effect of reducing the signal interference between the first frequency band and the second frequency band is more significant.
The interference parameter may be any parameter capable of reflecting the interference strength of each antenna, for example, the interference parameter may be the interference amplitude, and the like.
In addition, the above-mentioned determining the target antenna among the multiple antennas based on the interference parameters of the multiple antennas may be that the terminal determines the target antenna among the multiple antennas according to a preset rule associated with the interference parameters, for example, may determine an antenna with the largest interference parameter among the multiple antennas as the target antenna, and so on.
As shown in table 1 below, the relationship between the modulation mode and the demodulation threshold (i.e. the signal-to-noise ratio) under EN-DC is shown, wherein the higher the modulation mode is, the higher the demodulation threshold is, and the demodulation threshold is
256QAM >64QAM >16QAM > QPSK, i.e. the higher the modulation mode is, the higher the requirement on the quality of the signal is, the terminal usually has multiple antennas (e.g. 4 × 4MIMO), each antenna transmits different information, EN-DC interference is strongly correlated with transmission, i.e. the interference of the receiving antenna close to TX is stronger, under the condition of poor received signal, the modulation mode of the antenna (antenna with strong interference) can be changed according to the interference strength of the current antenna to improve the receiving performance, so that under the condition of signal interference between the first frequency band and the second frequency band, the modulation mode of the antenna can be adjusted to the modulation mode with a lower demodulation threshold, and the purpose of reducing the signal interference between the first frequency band and the second frequency band can be achieved.
TABLE 1 correspondence between modulation mode and demodulation threshold (i.e., SNR) under EN-DC
In this embodiment, the modulation mode of the adjustment target antenna may be that the modulation mode of the adjustment target antenna is adjusted to a target modulation mode, and a demodulation threshold of the target modulation mode is lower than a demodulation threshold of the current modulation mode, for example, in a case that it is determined that there is signal interference, the terminal may compare a demodulation threshold of the current modulation mode with a demodulation threshold of each modulation mode, and determine the modulation mode whose demodulation threshold is closest to and smaller than the demodulation threshold of the current modulation mode as the target modulation mode.
In some embodiments, the adjusting the modulation scheme of the target antenna includes:
determining a target demodulation threshold of the target antenna based on the interference parameter of the target antenna;
and adjusting the modulation mode of the target antenna to a modulation mode corresponding to the target demodulation threshold.
Here, the terminal may determine the target demodulation threshold according to the interference parameter of the target antenna, and adjust the modulation mode of the target antenna to the modulation mode corresponding to the target demodulation threshold (i.e., the target modulation mode), so that the determined target modulation mode is more appropriate, and the effect of reducing the signal interference between the first frequency band and the second frequency band is further improved.
