Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a signal transmission method, a signal transmission device and a terminal.
Background
With the rapid development of communication technology, mobile communication enters the 5G era. In a 5G NR, which is a global 5G (fifth generation mobile communication) communication standard designed based on an OFDM brand new air interface, a 5G spectrum is expanded, a plurality of frequency bands between 3.3G and 5G are newly added, and a common frequency band range of a WIFI 5G based on an IEEE 802.11 wireless local area network communication standard includes 5170 and 5835MHz (which is actually planned but temporarily unused and includes 4910 and 5170MHz), so that an N79 frequency band (4.4-5.0Ghz) in the 5G NR is very close to a first channel of a 5.1G frequency band of the WIFI 5G, and a lot of mutual interference will be generated between the 5G NR and the WIFI 5G in a coexisting scene.
Due to the limited external dimensions of the current portable terminal (e.g., a mobile phone), the WIFI antenna supporting WIFI signal transmission and the air interface antenna supporting 4G/5G signal transmission in the terminal are usually disposed at relatively close positions, even the antenna multiplexing design may occur, which results in a small antenna isolation between the WIFI antenna and the air interface antenna, and it is difficult to avoid large mutual interference occurring when WIFI 5G and 5G NR coexist through antenna isolation, while the N79 frequency band in 5G NR is very close to the first channel of the 5.1G frequency band of WIFI 5G, and based on the current frequency device manufacturing technology, it is difficult to manufacture a filter device for filtering near-band interference in such a close frequency band, so that, when the WIFI signal is transmitted in 5G, the bottom noise is usually raised, and large noise enters into the received signal when the 5G NR based N79 frequency band is used for communication, affecting the reception performance of the 5G NR. Particularly, under the condition that the intensity of a noise signal is high due to 5G WIFI signal transmission, high power enters a receiving module of the 5G NR, corresponding devices are damaged, and the communication reliability of the 5G NR is greatly influenced.

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.
In one embodiment, a signal transmission method is provided, which is mainly directed to signal transmission in a coexistence scenario of 5G NR and WIFI 5G. The 5G NR is a global 5G communication standard designed based on an OFDM brand-new air interface, and the WIFI 5G is a WIFI communication protocol designed in an IEEE 802.11 wireless local area network communication standard and aiming at a 5G hotspot.
The signal transmission method is implemented in a terminal. The terminal comprises a first WIFI antenna and a second WIFI antenna which are used for transmitting WIFI 5G signals and an air interface antenna which is used for transmitting 5G NR signals.
And the antenna isolation between the second WIFI antenna and the air interface antenna is greater than a preset communication isolation threshold value. The communication isolation threshold is an antenna isolation lower limit value between antennas, which does not cause mutual interference in signal transmission between the antennas, and in this embodiment, the communication isolation threshold may be preset for engineering experience or experimental simulation data in a 5G NR and WIFI 5G coexistence scene, and no specific numerical value limitation is made here.
In a more specific embodiment, the first WIFI antenna and the air interface antenna are disposed at a first end of the terminal, the second WIFI antenna is disposed at a second end of the terminal, and an antenna isolation corresponding to a spatial distance between the first end and the second end of the terminal is greater than a preset communication isolation threshold. The first and second ends of the terminal may be selectively arranged according to a specific size or shape of the terminal. For example, the first end of the terminal may be the upper portion of the terminal, and the second end of the terminal may be the lower portion of the terminal, as shown in fig. 1, the air interface antenna and the first WIFI antenna are disposed on the upper portion of the terminal, the second WIFI antenna is disposed on the lower portion of the terminal, and the space distance between the air interface antenna and the second WIFI antenna is relatively long, so that a relatively large antenna isolation can be obtained, which is greater than a preset communication isolation threshold value.
As shown in fig. 2, the signal transmission method in this embodiment includes: step 201-step 203.
The air interface environment channel is an air interface channel related in a network environment in which the terminal currently works. In this embodiment, in the flows of air interface paging, access and the like designed in the 5G NR air interface standard, after the terminal initiates a random access flow according to the received air interface paging message, the frequency band where the air interface channel for establishing communication is located is determined, and the air interface environment channel currently used for signal transmission by the terminal is determined.
In a more specific embodiment, the air interface antenna is used for transmitting not only the 5G NR signal but also the 4G signal. The 4G signal refers to a communication signal transmitted based on a fourth generation mobile communication standard. The air interface antenna simultaneously supports transmission of 4G signals and 5G NR signals, so that the terminal can support various communication standards, and the equipment has a wider application range. Correspondingly, in step 201, by detecting whether the current terminal is registered in the 4G frequency band or the 5G NR frequency band, when it is determined that the terminal is registered in the 4G frequency band, it may be determined that the air interface environment channel does not include the N79 channel supporting the N79 frequency band in the 5G NR, and the detection is no longer continued to determine the air interface environment channel, and when it is determined that the terminal is registered in the 5G NR frequency band, it is detected and determined whether the air interface environment channel includes the N79 channel in the procedures of paging, random access, and the like of the 5G NR communication standard, so as to improve the processing efficiency.
The N79 frequency band (4.4-5.0Ghz) in the 5G NR is very close to the first channel of the 5.1G frequency band of the WIFI 5G (the WIFI 5G frequency band comprises 5170 + 5835MHz and 4910 + 5170Mhz), and when signals are transmitted through the N79 channel, large mutual interference is generated between the signals and the transmission of WIFI 5G signals.
Under the condition that the air interface environment signal comprises an N79 channel supporting an N79 frequency band in 5G NR, the 5G NR signal is transmitted through the air interface antenna, the WIFI 5G signal is transmitted through the second WIFI antenna, and the antenna isolation degree between the air interface antenna and the second WIFI antenna, which is greater than a preset communication isolation degree threshold value, can be used for preventing the 5G NR signal transmitted through the air interface antenna from being interfered by the WIFI 5G signal transmitted by the second WIFI antenna, so that the receiving performance of the 5G NR signal is effectively ensured, meanwhile, the phenomenon that a large noise intensity caused by the WIFI 5G signal is accessed into the 5G NR signal receiving module under an extreme condition can be avoided, related devices are damaged, and the reliability of 5G NR communication is ensured. The normal work of the 5G NR is effectively guaranteed under the coexistence scene of the 5G NR and the WIFI 5G, and better network communication experience is provided for users through the fact that the 5G NR can meet the high-speed transmission rate taking megabits per second (Gbps) as a unit.
By taking the specific settings of the first WIFI antenna, the second WIFI antenna, and the air interface antenna as shown in fig. 1 as an example, when the air interface environment signal includes an N79 channel supporting an N79 frequency band in 5G NR, the 5G NR signal is transmitted through the air interface antenna arranged at the upper portion of the terminal, and the WIFI 5G signal is transmitted through the second WIFI antenna arranged at the lower portion of the terminal, so that the antenna isolation greater than the preset communication isolation threshold value can be obtained through a relatively long spatial distance between the air interface antenna and the second WIFI antenna, and the influence of noise caused by the transmission of the WIFI 5G signal on the reception performance of the 5G NR signal is avoided. Meanwhile, the 5G NR signal is sent through an air interface antenna in the form of an upper antenna on the upper part of the terminal, so that the influence of the use environment on the transmission performance of the antenna caused by the fact that a user holds the lower part of the terminal when the user generally uses the terminal can be avoided, the normal work of the 5G NR is preferentially ensured under the scene that the 5G NR and the WIFI 5G coexist, the high-speed transmission rate with gigabit per second (Gbps) as a unit is met through the 5G NR, the theoretical transmission speed with the gigabit per second (Mbps) as a unit can only be provided for WIFI 5G, and better network communication experience is provided for the user.
When the air interface environment channel does not include the N79 channel, the air interface environment signal may include a channel supporting a frequency band other than N79 in the 5G NR or a 4G channel supporting a 4G frequency band, the frequency band of these channels is relatively far apart from the frequency band of the WIFI 5G signal, and when the signal of these channels is transmitted, no large mutual interference is generated with the transmission of the WIFI 5G signal.
When the air interface environment signal does not include the N79 channel, the configuration terminal transmits the 5G NR signal through the air interface antenna and transmits the WIFI 5G signal through the first WIFI antenna, and the WIFI 5G signal can be transmitted through the first WIFI antenna which does not need to form high antenna isolation degree with the air interface antenna, so that the antenna transmission environment similar to the 5G NR signal transmission can be obtained through the transmission of the WIFI 5G signal, and the transmission performance of the WIFI 5G signal is ensured on the basis of effectively ensuring the transmission performance of the 5G NR signal.
For example, as shown in fig. 1, when the air interface environment signal does not include an N79 channel supporting an N79 frequency band in 5G NR, the air interface antenna arranged on the upper portion of the terminal transmits a 5G NR signal, and the first WIFI antenna arranged on the upper portion of the terminal transmits a WIFI 5G signal, so that the transmission of the 5G NR signal and the WIFI 5G signal can be performed, the influence on the antenna transmission performance, which is caused by the fact that a user generally holds the lower portion of the terminal for use, can be avoided, and the transmission performance of the WIFI 5G signal can be ensured on the basis of effectively ensuring the transmission performance of the 5G NR signal.
The embodiment shown in fig. 2 has been described above.
In another embodiment, the first WIFI antenna and the air interface antenna are disposed at a first end of the terminal, the second WIFI antenna is disposed at a second end of the terminal, and an antenna isolation corresponding to a spatial distance between the first end and the second end of the terminal is greater than a preset communication isolation threshold, in this embodiment, the implemented signal transmission method may further include, in addition to the steps shown in fig. 2:
in the process of starting up the terminal each time, the 5G NR signal is transmitted through the air interface antenna, and the WIFI 5G signal is transmitted through the first WIFI antenna.
For example, the specific settings of the first WIFI antenna, the second WIFI antenna, and the air interface antenna may be as shown in fig. 1. When a user uses a terminal, the user generally holds the lower part of the terminal to use the terminal, which affects the performance of an antenna arranged at the lower part of the terminal. When the terminal is started up each time, the 5G NR signal is transmitted through the air interface antenna arranged on the upper portion of the terminal, the WIFI 5G signal is transmitted through the first WIFI antenna arranged on the upper portion of the terminal, the antenna performance cannot be influenced because a user holds the lower portion of the terminal for use, the 5G NR signal and the WIFI 5G signal are transmitted and cannot be influenced by the use environment of the terminal, and better signal transmission performance is obtained.
In another embodiment, in a case that the air interface environment channel does not include the N79 channel, after the WIFI 5G signal is transmitted through the first WIFI antenna, the signal transmission method further includes:
and under the condition that the air interface environment channel comprises the N79 channel, switching to transmit a WIFI 5G signal through the second WIFI antenna.
In this embodiment, the method may further include: under the condition that the air interface environment channel includes the N79 channel, after the WIFI 5G signal is transmitted through the second WIFI antenna, the implemented signal transmission method further includes:
and under the condition that the air interface environment channel does not comprise the N79 channel, switching to transmit a WIFI 5G signal through the first WIFI antenna.
After the WIFI 5G signal is transmitted through the first WIFI antenna or the second WIFI antenna, an air interface environment channel used for signal transmission by the terminal is continuously determined, the antenna used for transmitting the WIFI 5G signal is switched according to the actual state change of the air interface environment channel, the antenna transmission channel of the WIFI 5G signal can be dynamically adjusted in real time according to the change of the air interface environment of the detection terminal, the influence of the transmission of the WIFI 5G signal on the transmission performance of the 5G NR signal can be effectively avoided in real time, the transmission reliability of the 5G NR signal is ensured to be safely acquired by the 5G NR device, and the transmission performance of the WIFI 5G signal can be dynamically ensured in real time on the premise that the transmission performance of the 5G NR signal is not influenced.
In yet another embodiment, a controller is included in the terminal. The controller is used for controlling the connection or disconnection of the first connection path and the connection or disconnection of the second connection path. The first connecting channel is used for connecting the first WIFI antenna, and the second connecting channel is used for connecting the second WIFI antenna. In this embodiment, step 202 shown in fig. 2 is implemented to transmit a WIFI 5G signal through a second WIFI antenna, which includes:
step 2021, controlling the first connection path to be disconnected and connecting the second connection path through the controller;
and implementing the WIFI 5G signal transmission through the first WIFI antenna in step 203 shown in fig. 2, including:
step 2031, controlling the first connection path to be disconnected and connecting the second connection path by the controller.
The controller is arranged in the terminal to control the connection channel between the terminal and the first WIFI antenna and between the terminal and the second WIFI antenna, so that the terminal can be rapidly and efficiently configured to switch between the first WIFI antenna and the second WIFI antenna to transmit WIFI 5G signals according to the change of an air interface environment in which the terminal works, and the configuration efficiency is further improved on the basis of effectively avoiding the influence of the transmission of the WIFI 5G signals on the transmission performance of the 5G NR signals.
In a more specific embodiment based on the above embodiment, the terminal includes, in addition to the controller in the above embodiment, a single-pole double-throw switch for turning on or off the first connection path and turning on or off the second connection path according to the control of the controller. The Single Pole Double Throw Switch (SPDT) may be configured as shown in fig. 3, and the controller is connected to the first WIFI antenna and the second WIFI antenna, and the controller controls whether to switch on the first connection path with the first WIFI antenna or the second connection path with the second WIFI antenna, and accordingly, when the Single Pole Double Throw switch is switched on, the first connection path and the second connection path are disconnected, and when the Single Pole Double Throw switch is switched on, the connection path with the first WIFI antenna is correspondingly disconnected.
In this embodiment, the step 2021 specifically includes:
the controller controls the single-pole double-throw switch to be connected with the second connecting channel and disconnected with the first connecting channel;
and step 2031 of performing specifically comprises:
and controlling the single-pole double-throw switch to be connected with the first connecting channel and disconnected with the second connecting channel through the controller.
Through set up single-pole double-throw switch in the terminal, by the single control of controller to single-pole double-throw switch, can realize simultaneously that the control of switch on one disconnection of two connecting channels of terminal and first WIFI antenna and second WIFI antenna, further improve control efficiency.
It should be understood that, the two connection paths of the terminal and the first WIFI antenna and the second WIFI antenna are independent from each other, and on the basis of the disclosure of this embodiment, a person skilled in the art may perform a simple modification without creativity in consideration of simple design or setting cost, for example, setting independent switches for the two connection paths of the terminal and the first WIFI antenna and the second WIFI antenna to control.
In another embodiment, the terminal further comprises a low-pass filter for processing the signal of the N78 frequency band in the 5G NR. The low-pass filter may be disposed between the transceiver module for the N78 frequency band signal and the air interface antenna, as shown in fig. 3.
In this embodiment, in addition to the signal transmission method shown in fig. 2, the method further includes:
and under the condition that the air interface environment channel does not comprise an N79 channel and the air interface environment channel comprises an N78 channel supporting an N78 frequency band in 5G NR, processing the 5G NR signal transmitted through an air interface antenna by adopting a low-pass filter.
The frequency range of the N78 in the 5G NR is 3300Mhz-3800Mhz, although the frequency range is not very close to the frequency range of WIFI 5G (5170-5835MHz and 4910-5170Mhz), under the condition that the signal intensity of WIFI 5G is large, the bottom noise of the WIFI 5G signal can still be raised, so that the noise affects the signal transmission of an N78 channel supporting an N78 frequency band, when the air interface environment channel does not include the N79 channel but includes the N78 frequency band, the WIFI 5G signal is continuously transmitted by using the first WIFI antenna without switching the second WIFI antenna, so that the WIFI 5G signal can be ensured to acquire an antenna transmission environment similar to the transmission of the 5G NR signal, and the transmission performance of the WIFI 5G signal is ensured on the basis of effectively ensuring the transmission performance of the 5G NR signal; meanwhile, the 5G NR signals transmitted through the air interface antenna are processed by adopting the low-pass filter, so that the interference of the WIFI 5G signal transmission on the 5G NR signals can be inhibited, and the transmission of the 5G NR signals is not influenced by the WIF 5G signals.
