Description
Technical Field
The present disclosure relates to the field of electronic devices, and in particular, to an information transceiving control method and apparatus, an electronic device, and a storage medium.
Background
The mainstream architecture of the fifth generation mobile communication technology (5G for short) includes: SA (stand-alone) architecture and NSA (Non-stand-alone) architecture. In the NSA architecture, 5G needs to rely on an existing LTE (long Term Evolution) network to carry control signaling and control plane data. But a complete end-to-end network does not need to be deployed, and only the access network needs to be deployed to improve the transmission capability of the air interface, so that rapid deployment can be realized.
At present, in order to ensure smooth transition of a communication system, an NSA network architecture is generally adopted in an initial stage, that is, a terminal is required to have dual connection capabilities of LTE and 5G, so that LTE and 5G modules of a mobile terminal need to work simultaneously. Therefore, in order to meet the requirement of high speed and low delay under 5G communication, the number of transceiving modules and antennas of the mobile terminal is further increased, wherein MIMO (multiple input multiple output) technology is also increasingly applied, and gradually becomes the standard configuration of the 5G mobile terminal. However, in practical application, the MIMO technology may have the situations of short antenna layout distance of each system, multiplexing of antennas, and the like, and it is difficult to ensure the isolation between the antennas, so that the coexistence of 4G and 5G may cause interference.
In addition, due to the requirements of 5G on high bandwidth, high speed and low delay, a higher frequency band of 3.3G-5 GHz is newly added to 5G. The higher the radio wave frequency is, the larger the spatial loss of the electromagnetic wave in the free space is, the worse the diffraction effect on the obstacle is, and the coverage radius of the 5G base station is reduced relative to that of the 4G base station, so that in the initial stage of the 5G network, the coverage of the 5G signal has more blind areas, and further the problem that the mobile terminal cannot receive the signal in some areas or the signal is weak is caused.
Moreover, the 2G, the 3G, the 4G and the 5G have a common frequency range, which results in a very complex network environment, and the mobile terminal is easily interfered by a strong signal, so that the problem that the signal cannot be received or the signal is weak occurs.

The information transmission and reception control method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, a flowchart of an information transceiving control method according to an embodiment of the present application is shown, and fig. 2,3, and 4 show an information transceiving system according to an embodiment of the present application, where the information transceiving control method is applied to the information transceiving system, and the information transceiving system includes: a first transceiver circuit 11; the first transceiver circuit comprises an external low noise amplifier 111; the method may specifically comprise the steps of:
In the embodiment of the present application, the current block error rate refers to a block error rate of information received by the first transceiver circuit when the first transceiver circuit is receiving information; the block error rate (BLER) is a percentage of blocks transmitted (to be received) by all the other parties when the first transceiver circuit receives information.
In the embodiment of the present application, the reason why the BLER value is higher is that, firstly, the mobile terminal is far away from the base station, for example, when the cell edge is reached, the BLER value is higher because the signal of the information received by the first transceiver circuit is weak; and secondly, the signal which influences the information receiving of the first transceiver circuit when the signal interference exists.
In the embodiment of the present application, it is determined whether a signal of information received by the first transceiver circuit is affected or the signal is very weak by acquiring the current block error rate.
In an embodiment of the present application, referring to fig. 2, there is provided an information transceiving system disposed in a mobile terminal, wherein the information transceiving system includes: a first transceiver circuit 11 and a second transceiver circuit 12; the information transceiving system further comprises: a transceiver module 13; the transceiver module 13 includes: a 5G transceiver unit 131 and a 4G transceiver unit 132; wherein, one end of the first transceiver circuit 11 is connected to the 5G transceiver unit. Specifically, the first transceiver circuit 11 includes: an external LNA (Low Noise Amplifier) 111, an internal LNA112, and a first antenna 113, which are connected to each other. The second transceiver circuit 12 includes: a second antenna 121; one end of the second transceiving circuit is connected with the 4G transceiving unit; in the embodiment of the present application, the purpose of the internal LNA and the external LNA is to reduce the link noise figure, so as to obtain better receiving performance of the 5G Transceiver unit 131(5G-Transceiver), and in order to prevent saturation of the 5G-Transceiver caused by excessive gain, it is generally necessary to coordinate the gains of the internal LNA and the external LNA on the first Transceiver circuit 11, so as to operate the 5G-Transceiver in the non-saturation region, thereby ensuring the performance of receiving and sending information.
In the embodiment of the present application, since the interference of the second antenna 121 is received by the first antenna 113, and further the first transceiver circuit 11 is affected, on one hand, the external LNA may be saturated, and the first transceiver circuit may be blocked, which affects the performance of transmitting and receiving information; on the other hand, after amplification by the external LNA, 5G-Transceiver blocking may be caused, thereby affecting the performance of transmitting and receiving information.
In the embodiment of the present application, referring to fig. 3, another information transceiving system is provided, in which a first transceiving circuit 11 and a second transceiving circuit 12 are connected to a same transceiver 13 and a same antenna, and the first transceiving circuit 11 and the second transceiving circuit 12 perform transceiving of information in different frequency bands; for example, the first transceiver circuit transmits and receives information in the B41 frequency band, and the second transceiver circuit 12 transmits and receives information in the B3 frequency band; alternatively, the first transceiver circuit 11 may transmit and receive information in the N78 band, and the second transceiver circuit 12 may transmit and receive information in the B3 band.
In the embodiment of the present application, the transmission path (TX) of the second transceiver circuit 12 may cause interference to the reception path (RX) of the first transceiver circuit 11 through wire coupling, so that the external LNA111 is saturated, and the quality of information transmission and reception of the information transmission and reception system is affected.
In the embodiment of the present application, when the operating power of the second transceiver circuit 12 is positively correlated with the interference to the first transceiver circuit 11, that is, the operating power of the second transceiver circuit 12 is higher, the interference to the first transceiver circuit is larger.
Referring to fig. 4, a further information transceiving system is provided, which comprises only the first transceiving circuit 11, wherein the external LNA111 is saturated due to interference of the external strong interference signal X, which affects the sensitivity of the first transceiving circuit 11 for receiving information.
And step 102, acquiring the current reference signal receiving power of the first transceiver circuit when the current block error rate is greater than a first preset threshold.
In the embodiment of the application, the first preset threshold value can be determined according to actual conditions; for example, it may be determined according to a usage scenario of the mobile terminal that, when the user is using a chat tool or watching a function that needs to be implemented by networking, such as online video, the first preset threshold is set to be lower (4%), when the user is using a function that can be implemented without networking, such as offline video watching or taking a picture, the first preset threshold may be set to be higher (6%), and when the user is not using the mobile terminal, the first preset threshold may be set to be highest (8%); in the embodiment of the present application, the first preset threshold may also be set according to international standards (5%).
In the embodiment of the application, if the current block error rate is greater than a first preset threshold, it indicates that a signal of a position where the mobile terminal is far away from the base station is weak or the first transceiver circuit is interfered by the outside; wherein, the first transceiver circuit is interfered by the external interference includes three situations as shown in fig. 2-4.
In this embodiment of the present application, the current reference signal receiving power of the first transceiver circuit refers to the reference signal receiving power of the first transceiver circuit when receiving information; here, Reference Signal Receiving Power (RSRP) is an average value of Signal powers received on all Resource Elements (REs) that carry Reference signals only within a certain symbol.
In the embodiment of the present application, when the RSRP value is higher, it indicates that the external interference to the first transceiver circuit is stronger, and when the RSRP value is higher, the SINR (Signal to interference plus noise ratio) of the first transceiver circuit is lower, so that the BLER value is higher. Therefore, the interference condition of the external to the first transceiving circuit can be more conveniently and accurately judged by acquiring the current reference signal receiving power.
And 103, controlling the external low noise amplifier to receive information in a bypass mode under the condition that the current reference signal receiving power is greater than a second preset threshold value.
In the embodiment of the present application, the second predetermined threshold may be determined in advance; when the current block error rate is greater than a first preset threshold and the current reference signal receiving power is greater than a second preset threshold, it can be said that the interference of the outside to the first transceiver circuit is very large, and at this time, if the external low noise amplifier is controlled to receive information in the enable mode, the external low noise amplifier is saturated, so that the first transceiver circuit is blocked, the sensitivity of receiving information is reduced, and therefore the external low noise amplifier is controlled to receive information in the bypass mode.
In the embodiment of the application, two sets of parameters are integrated in software at the development and design stage of the mobile terminal, and are used for adjusting the gain of the external LNA and respectively correspond to two modes of enabling and bypassing (bypass) of the external LNA, wherein the enabling mode is that the external LNA performs signal amplification, and the bypass mode is that the external LNA does not perform signal amplification. Wherein each set of parameters comprises: calibration parameters, gain mapping parameters, software configuration related parameters, and the like; these parameters are written into a Non-volatile memory (NV) and can be called during use according to the use situation.
And 104, controlling the external low noise amplifier to receive information in an enabling mode under the condition that the current reference signal receiving power is less than or equal to a second preset threshold value.
When the current block error rate is greater than the first preset threshold and the current reference signal receiving power is less than or equal to the second preset threshold, it can be shown that the interference of the outside to the first transceiver circuit is very small, and the mobile terminal may be in an area with weak signals, so that the external low noise amplifier is controlled to receive information in an enable mode at this time, and the sensitivity of receiving information is improved.
In the embodiment of the application, under the condition that the current block error rate is greater than a first preset threshold, whether the first transceiver circuit is blocked under external interference is judged according to the magnitude of the current reference signal receiving power, so as to adjust the working mode of the external low noise amplifier, wherein under the condition that the current reference signal receiving power is less than or equal to a second preset threshold, the external low noise amplifier is controlled to receive information in an enabling mode, so that the sensitivity of the first transceiver circuit for receiving information can be improved; and under the condition that the current reference signal receiving power is greater than a second preset threshold value, controlling the external low-noise amplifier to receive information in a bypass mode to prevent the blockage of the first transceiver circuit from influencing the sensitivity of the first transceiver circuit for receiving information, thereby improving the performance of the mobile terminal for receiving information.
Referring to fig. 5, a flowchart of another information transceiving control method according to an embodiment of the present application is shown, which may specifically include the following steps:
In the embodiment of the present application, the mobile terminal is located at a close distance from the base station, that is, the signal when the first transceiver circuit receives the information is not affected. The first transceiver circuit is in a non-interference state, namely no other circuit or other external signals interfere the first transceiver circuit; and taking the current block error rate as a reference block error rate, wherein the current reference block error rate is the first preset threshold.
In the embodiment of the application, the first transceiver circuit receives information in a bypass mode.
In the embodiment of the present application, the reference signal received power of the information received when the first transceiver circuit is in a non-interference state and the reference block error rate is the first preset threshold is set as the first reference signal received power; when the reference block error rate is the first preset threshold and the reference signal power is greater than the first reference signal receiving power, it indicates that the first transceiver circuit is subjected to external interference.
In the embodiment of the application, the first reference signal received power of the first transceiver circuit in the non-interference state and with the reference block error rate being the first preset threshold value is obtained and can be used as a reference for subsequently judging whether the first transceiver circuit is interfered.
In the embodiment of the application, the external signals with the first preset power value are sequentially added to interfere the first transceiver circuit, and when the reference block error rate is greater than the first preset threshold, the external signals with the previous power are adopted to interfere the first transceiver circuit, so that the reference block error rate is the received information at the first preset threshold; specifically, the information is received when the first transceiver circuit is in a non-interference state and the reference block error rate is the first preset threshold value, then, the external signal with the first preset power value is adopted to interfere the first transceiver circuit, the reference block error rate at the moment is obtained, if the reference block error rate is still the first preset threshold, adopting an external signal with 2 times of the first preset power value to interfere the first transceiver circuit to obtain the reference block error rate at the moment, if the reference block error rate is still the first preset threshold, continuing to circulate until the first transceiver circuit is interfered by an external signal with N times of first preset power value, and when the obtained reference block error rate is larger than the first preset threshold, controlling the first transceiver circuit to be interfered by the first transceiver circuit with N-1 times of first preset power value as the preset power value, and at the moment, the reference block error rate when the first transceiver circuit receives information is the first preset threshold.
In the embodiment of the application, the first transceiver circuit receives information in a bypass mode.
In this embodiment, at this time, the second reference signal received power of the first transceiver circuit is the reference signal received power of the first transceiver circuit under the interference of the external signal with the critical power value. If the reference signal received power of the first transceiver circuit is greater than the second reference signal received power, it indicates that the interference of the external environment to the first transceiver circuit has an effect to cause the jamming of the first transceiver circuit, and therefore, the first transceiver circuit is set to the bypass mode. If the reference signal receiving power of the first transceiver circuit is less than the second reference signal receiving power, it indicates that the interference of the outside to the first transceiver circuit will not cause the blockage of the first transceiver circuit, therefore, the first transceiver circuit is set to the enabling mode at this time to improve the sensitivity of the first transceiver circuit for receiving information.
In the embodiment of the present application, when the first reference signal received power is smaller than the second reference signal received power, it indicates that the test is abnormal, and after the abnormality needs to be eliminated, the first reference signal received power and the second reference signal received power are obtained again.
In this embodiment of the present application, step 205 includes: when the second reference signal received power is greater than the first reference signal received power, determining the second reference signal received power as the second preset threshold.
The second reference signal received power may be directly determined as a second preset threshold, and when the reference signal received power of the first transceiver circuit is greater than the second reference signal received power, it indicates that the first transceiver circuit is greatly interfered by the outside, and the first transceiver circuit is easily blocked. When the reference signal receiving power of the first transceiver circuit is smaller than the second reference signal receiving power, it indicates that the external interference to the first transceiver circuit is very small, and the reason why the current block error rate is larger than the first preset threshold value may be that the mobile terminal is far away from the base station, so that the first transceiver circuit is not blocked.
In another embodiment of the present application, step 205 includes: determining a difference between the second reference signal received power and the first reference signal received power when the second reference signal received power is greater than the first reference signal received power; determining an error value according to the difference value; determining a sum of the first reference signal received power, the difference value, and the error value as the second preset threshold.
In the embodiment of the present application, when the difference is larger, it indicates that the sensitivity of the first transceiver circuit to the interference is lower, so that the error value can be set to be larger, and when the difference is smaller, it indicates that the sensitivity of the first transceiver circuit to the interference is higher, so that the error value can be set to be smaller. Wherein determining an error value from the difference value comprises: multiplying the difference value by a preset percentage to be the error value, or determining the error value according to the range to which the difference value belongs; for example, if the preset percentage is set to 5%, the error value is the difference value × 5%; setting the difference value range to be 0-20,20-40,40-60 and the like, and setting the corresponding error value to be 2,3 and 4; then the error value is 3 when the difference is 30.
In the embodiment of the present application, the first reference signal received power is R1, the second reference signal received power is R2 th, and the difference C between the second reference signal received power R2 and the first reference signal received power R1; determining an error value B according to the difference value C; the second preset threshold is: r1+ C + B.
In the embodiment of the present application, considering that the mobile terminal is in different positions and under different types of interference conditions (three types of interference shown in fig. 2-4), and when the mobile terminal is different, the value of the second reference signal received power is different, so an error value can be set so that the second preset threshold covers various conditions.
In the embodiment of the present application, refer to step 101, which is not described herein again.
And step 207, controlling the external low noise amplifier to receive information in an enabling mode under the condition that the current block error rate is less than or equal to a first preset threshold value.
In the embodiment of the present application, if the current block error rate is less than or equal to the first preset threshold, it indicates that the sensitivity of the first transceiver circuit for receiving and transmitting information is high, and the first transceiver circuit is not located at a position far away from the base station, and there is no strong external interference.
And 208, acquiring the current reference signal receiving power of the first transceiver circuit when the current block error rate is greater than a first preset threshold.
In the embodiment of the present application, reference is made to step 102, which is not described herein again.
In the embodiment of the present application, refer to step 103, which is not described herein again.
In the embodiment of the present application, reference is made to step 104, which is not described herein again.
This application embodiment only needs to realize through software, does not increase the hardware cost, through writing into two kinds of modes at software and corresponding the parameter, can solve information transceiver system because of the antenna, walk the influence that the line isolation is not enough to lead to interference between the circuit to information transceiver system receiving and dispatching information, wherein, sets up external LNA into the Bypass mode, calls the Bypass mode and corresponds the parameter, can reduce the gain, avoids blockking. When the interference is small, parameters corresponding to the external LNA enabling mode are called, and the link sensitivity is increased.
In the embodiment of the application, the working scene of the mobile terminal is not changed, so that the second preset threshold value can be determined once when the mobile terminal is used for the first time, and the second preset threshold value is directly used without being acquired again when the mobile terminal is used subsequently, thereby reducing the workload of the mobile terminal.
In the embodiment of the present application, since the operating environment of the first transceiver circuit changes in real time, the steps 206 to 210 need to be executed in real time, so that the operating mode of the first transceiver circuit can be adjusted in real time. The performance of information receiving and transmitting of the information receiving and transmitting system is improved. For example, the current block error rate of the first transceiver circuit may be acquired every 10s, 20s or 30 s.
In the embodiment of the application, only two sets of parameters need to be configured in software, and the hardware structure does not need to be changed, so that the blockage of the first transceiver circuit can be avoided, and the sensitivity of the first transceiver circuit for receiving and transmitting information is increased. According to the reference signal receiving power of the first transceiving circuit of the mobile terminal, the optimal receiving path of the first transceiving circuit is flexibly configured, the sensitivity of an information transceiving system is effectively improved, the blocking interference is avoided, the communication quality of the mobile terminal is enhanced, and the user experience is further improved.
In the embodiment of the present application, when the current block error rate is greater than a first preset threshold, whether the first transceiver circuit is blocked under external interference is determined according to the magnitude of the current reference signal receiving power, so as to adjust the working mode of the external low noise amplifier, wherein in the case that the current reference signal receiving power is less than or equal to a second preset threshold, the external low noise amplifier is controlled to receive information in an enable mode, so that the sensitivity of the first transceiver circuit for receiving information can be improved; and under the condition that the current reference signal receiving power is greater than a second preset threshold value, controlling the external low-noise amplifier to receive information in a bypass mode to prevent the blockage of the first transceiver circuit from influencing the sensitivity of the first transceiver circuit for receiving information, thereby improving the performance of the mobile terminal for receiving information.
