Description

Wireless device, method and related equipment

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a wireless device, a method, and a related apparatus.

Background

The radio frequency device is an important component of various wireless devices such as smart phones, wireless routers and the like, and bears the conversion function of digital baseband signals and radio frequency signals. Due to differences in manufacturing processes, device performance, and the like of the rf devices, differences exist in the performance of the rf path of each wireless device. Moreover, the difference may greatly reduce the quality and demodulation capability of the device transmission signal, and at the same time, the change of the external environment, such as temperature, may also affect the quality and demodulation capability of the device transmission signal.

Therefore, in order to compensate for the differences of the radio frequency devices and the influence caused by environmental changes, all wireless devices using the radio frequency devices introduce a radio frequency calibration process, which includes actively transmitting radio frequency calibration data through the wireless devices to measure the deviation of a radio frequency transmission link, and performing difference compensation. However, when a certain path of the wireless device is performing the radio frequency calibration, other paths of the wireless device cannot perform normal traffic data transmission, and signals generated by the radio frequency calibration tend to leak to the air interface, thereby blocking normal traffic data transmission of other wireless devices. Obviously, the existing radio frequency calibration technology usually causes the wireless device to consume a large amount of resources during radio frequency calibration, reduces the utilization rate of an air interface and the throughput of the whole wireless service, and even greatly affects the internet experience of a user.

Disclosure of Invention

Embodiments of the present invention provide a wireless device, a method, and related equipment, which can make full use of resources of multiple radio frequency channels, and effectively improve utilization rate of air interfaces and throughput of wireless services.

In a first aspect, an embodiment of the present invention provides a wireless apparatus, which may include: the medium control module, K radio frequency access respectively with the medium control module is connected: the medium control module is used for generating M pieces of calibration data and N pieces of service data; m first radio frequency paths in the K radio frequency paths are respectively used for acquiring corresponding calibration data in the M calibration data and performing radio frequency calibration in a preset period, and N second radio frequency paths in the K radio frequency paths are respectively used for acquiring corresponding service data in the N service data and performing service transmission in the preset period; wherein K, M and N are integers greater than or equal to 1 and the sum of M and N is less than or equal to K.

In the embodiment of the present invention, when one or more radio frequency paths (for example, one or more first radio frequency paths) in the wireless device need to perform radio frequency calibration, one or more calibration data for radio frequency calibration may be generated by the media control module, and then the one or more radio frequency paths respectively obtain corresponding calibration data and perform radio frequency calibration within a preset period (for example, a period required for performing a round of radio frequency calibration on each radio frequency path in the wireless device). During this period, one or more pieces of service data for normal service transmission may also be generated by the media control module, so that when one or more first radio frequency paths in the wireless device perform radio frequency calibration, other radio frequency paths (e.g., one or more second radio frequency paths) of the wireless device may still obtain corresponding service data and perform service transmission within the preset period. Therefore, compared with the prior art that when one radio frequency channel of the wireless equipment is performing radio frequency calibration, and other radio frequency channels cannot perform normal service transmission, the embodiment of the invention can fully utilize the capacity and space resources of the plurality of radio frequency channels in the wireless equipment, so that during the radio frequency calibration of one or more radio frequency channels of the wireless equipment, the other radio frequency channels of the wireless equipment can still perform normal service transmission, thereby greatly improving the service transmission efficiency, reducing the resource occupation caused by the radio frequency calibration, and further improving the utilization rate of an air interface and the throughput of the wireless service.

In a possible implementation manner, each of the M first rf paths is an rf path for which the rf calibration is not completed in the preset period; each of the N second rf paths is an rf path for which the rf calibration has been completed in the preset period.

In the embodiment of the present invention, in the preset period, that is, in the process of performing a round of radio frequency calibration on each radio frequency path of the wireless device, a radio frequency path without radio frequency calibration may be referred to as a first radio frequency path, and other radio frequency paths of the wireless device, that is, a radio frequency path with radio frequency calibration completed, may be referred to as a second radio frequency path. In the embodiment of the invention, while the first radio frequency channel carries out radio frequency calibration, the second radio frequency channel can still be used for service transmission, and the first radio frequency channel and the second radio frequency channel are not influenced mutually. It is understood that the first rf path may be changed to the second rf path after the first rf path completes the rf calibration within the predetermined period. For example, when a new round of rf calibration is started, i.e. each rf path in the wireless device does not complete rf calibration in the preset period, each rf path may be referred to as a first rf path, and when the round of rf calibration is finished, i.e. each rf path in the wireless device completes rf calibration in the preset period, each rf path may be referred to as a second rf path. Obviously, each second rf path may be changed to the first rf path again when the next round of rf calibration arrives, and the process is repeated. That is, the circuit structures, component compositions, and the like of the first rf path and the second rf path may be consistent, and the first rf path and the second rf path may be changed according to a state of whether they complete rf calibration within the preset period. Therefore, compared with the prior art that when one radio frequency channel of the wireless equipment is performing radio frequency calibration, and other radio frequency channels cannot perform normal service transmission, the embodiment of the invention can fully utilize the capacity and space resources of multiple radio frequency channels in the wireless equipment, so that one or more second radio frequency channels of the wireless equipment can still perform normal service transmission during the radio frequency calibration of one or more first radio frequency channels of the wireless equipment, thereby greatly improving the service transmission efficiency, reducing the resource occupation caused by the radio frequency calibration, and further improving the utilization rate of an air interface and the throughput of the wireless service.

In one possible implementation, each of the K radio frequency paths includes: the device comprises a physical protocol processing module, a radio frequency module, a power amplifier and a diode; the radio frequency module is connected with the physical protocol processing module, the power amplifier is connected with the radio frequency module, the input end of the diode is connected with the power amplifier, and the output end of the diode is connected with the radio frequency module.

In the embodiment of the present invention, each rf path in the wireless device may be composed of a physical protocol processing module, a rf module, a power amplifier, a diode, and the like, where the rf module is connected to the physical protocol processing module, the power amplifier is connected to the rf module, an input end of the diode is connected to the power amplifier, and an output end of the diode is connected to the rf module. Thus, each rf path may perform rf calibration and service transmission, for example, the rf calibration may be performed when the rf path is a first rf path, and the service transmission may be performed when the rf path is a second rf path. The capacity and space resources of each radio frequency access are fully utilized, and the radio frequency calibration and service sending efficiency is improved.

In one possible implementation, when the radio frequency path is the first radio frequency path; the physical protocol processing module is used for acquiring the corresponding calibration data and forming a calibration frame based on the corresponding calibration data; the radio frequency module is used for receiving the calibration frame and carrying out signal modulation based on the calibration frame to obtain a first radio frequency signal; the power amplifier is configured to receive the first radio frequency signal output by the radio frequency module, and perform power amplification on the first radio frequency signal to obtain an amplified first radio frequency signal; the diode is used for obtaining corresponding detection voltage based on the amplified first radio frequency signal and transmitting the detection voltage back to the radio frequency module.

In the embodiment of the present invention, when the radio frequency path is the first radio frequency path, the corresponding calibration data may be acquired by the physical protocol processing module in the radio frequency path, and a calibration frame may be formed based on the calibration data and then transmitted to the radio frequency module. The radio frequency module carries out signal modulation according to the calibration frame and outputs a first radio frequency signal. Since the power of the rf signal (e.g., the first rf signal) modulated and output by the rf module is usually small, if the rf signal is directly transmitted through the antenna, the rf signal is generally not received by the antenna of another device due to the small power. Thus, the first radio frequency signal may be power amplified by a power amplifier. However, if the power of the amplified signal is too high, the signal is sent to the air interface through the antenna, and then interference may be generated on signals sent by other devices. Therefore, the power of the signal amplified by the power amplifier needs to be calibrated to ensure that the transmission power of the radio frequency signal is within a preset range. According to the embodiment of the invention, the diode connected with the power amplifier and the radio frequency module is used for obtaining the corresponding detection voltage based on the first radio frequency signal after power amplification, the detection voltage is transmitted back to the radio frequency module, and then the radio frequency module carries out radio frequency calibration based on the detection voltage so as to ensure the quality of the radio frequency signal.

In one possible implementation, when the radio frequency path is the second radio frequency path; the physical protocol processing module is used for acquiring the corresponding service data and forming a service frame based on the corresponding service data; the radio frequency module is used for receiving the service frame and carrying out signal modulation based on the service frame to obtain a second radio frequency signal; the power amplifier is configured to receive the second radio frequency signal output by the radio frequency module, and perform power amplification on the second radio frequency signal to obtain the amplified second radio frequency signal.

In the embodiment of the present invention, when the radio frequency path is the second radio frequency path, the corresponding service data may be acquired by the physical protocol processing module in the radio frequency path, and a service frame may be formed based on the service data and then transmitted to the radio frequency module. And the radio frequency module performs signal modulation according to the service frame and outputs a second radio frequency signal. Since the power of the rf signal (e.g., the second rf signal) modulated and output by the rf module is usually small, if the signal is directly transmitted through the antenna, the rf signal is generally not received by the antenna of another device due to the small power. Therefore, the second radio frequency signal can be power-amplified by the power amplifier to obtain the amplified second radio frequency signal, so as to ensure that the transmitted signal can be received by the antenna of other equipment.

In one possible implementation, the radio frequency calibration includes power calibration of a radio frequency signal; the radio frequency module is specifically configured to calibrate power of the radio frequency signal according to the detection voltage and a preset range.

In the embodiment of the present invention, since the power of the radio frequency signal (for example, the first radio frequency signal) modulated and output by the radio frequency module is often small, if the signal is directly transmitted through the antenna, the signal generally cannot be received by the antenna of another device due to the small power. Therefore, it is generally necessary to power-amplify the first rf signal by a power amplifier. However, if the power of the amplified signal is too high, the signal is sent to the air interface through the antenna, and then interference may be generated on signals sent by other devices. Therefore, the power of the signal amplified by the power amplifier needs to be calibrated to ensure that the transmission power of the radio frequency signal is within a preset range. The embodiment of the invention can carry out power calibration of the radio frequency signal based on the detection voltage and the preset range through the radio frequency module so as to ensure the quality of the radio frequency signal. Optionally, in some possible implementations, the radio frequency calibration may further include a center frequency calibration of a radio frequency path, and the like, which is not specifically limited in this embodiment of the present invention.

In a possible implementation manner, each of the radio frequency paths further includes: the antenna is connected with the output end of the power amplifier through a switch circuit, and the switch circuit comprises a plurality of switches; when the radio frequency path is the first radio frequency path, each switch in the plurality of switches is in a disconnected state, and is used for disconnecting a connection circuit between the power amplifier and the antenna, so as to obtain the detection voltage through the diode, and transmit the detection voltage back to the radio frequency module; and when the radio frequency path is the second radio frequency path, each switch of the plurality of sequentially connected switches is in a closed state, and is used for conducting the power amplifier and the connection circuit of the antenna so as to send the amplified second radio frequency signal to an air interface through the antenna.

In the embodiment of the present invention, the antenna and the power amplifier in each rf path are connected through a switch circuit, and the switch circuit may include a plurality of switches (for example, the switch may include an original antenna switch and one or more additional switches). When the first radio frequency path is used for radio frequency calibration, each switch in the switch circuit in the first radio frequency path is in an off state, and the switch circuit can be used for cutting off a connecting circuit of the power amplifier and the antenna so as to obtain the detection voltage through the diode and transmit the detection voltage back to the radio frequency module. Therefore, during radio frequency calibration, the isolation between the wireless device and the air interface can be further increased through the plurality of switches, and the amplified first radio frequency signal output by the power amplifier is more effectively prevented from leaking to the air interface through the antenna, so that interference of a leakage signal generated by the radio frequency calibration on normal service transceiving of other wireless equipment or other radio frequency paths (for example, one or more second radio frequency paths) of the wireless equipment is reduced. When the first radio frequency channel performs radio frequency calibration, the second radio frequency channel may perform service transmission, and at this time, each switch in the switch circuit in the second radio frequency channel is in a closed state, and may be used to turn on the connection circuit between the power amplifier and the antenna, so as to ensure that the amplified second radio frequency signal output by the power amplifier is transmitted to the air interface through the antenna, thereby completing service transmission. Therefore, when the first radio frequency channel is used for carrying out radio frequency calibration, the second radio frequency channel can still carry out normal service transmission, and the first radio frequency channel and the second radio frequency channel are not interfered with each other.

In a second aspect, an embodiment of the present invention provides a wireless method, which may include: generating M pieces of calibration data and N pieces of service data through a medium control module; determining M first radio frequency paths in K radio frequency paths connected with the medium control module, respectively receiving corresponding calibration data in the M calibration data through the M first radio frequency paths, and performing radio frequency calibration in a preset period; determining N second radio frequency paths in the K radio frequency paths, respectively receiving corresponding service data in the N service data through the N second radio frequency paths, and sending a service in the preset period; wherein K, M and N are integers greater than or equal to 1 and the sum of M and N is less than or equal to K.

In a possible implementation manner, the receiving, through the M first radio frequency paths, corresponding calibration data in the M calibration data and performing radio frequency calibration in a preset period includes: respectively acquiring the corresponding calibration data through the respective physical protocol processing modules in the M first radio frequency channels, and forming a calibration frame based on the corresponding calibration data; performing signal modulation on the calibration frame through the radio frequency modules in the M first radio frequency paths respectively to obtain respective first radio frequency signals of the M first radio frequency paths; respectively performing power amplification on the first radio frequency signals through the power amplifiers in the M first radio frequency paths to obtain the amplified first radio frequency signals of the M first radio frequency paths; respectively obtaining detection voltages corresponding to the M first radio frequency paths through respective diodes in the M first radio frequency paths based on the amplified first radio frequency signals of the M first radio frequency paths, and respectively returning the detection voltages corresponding to the M first radio frequency paths to respective radio frequency modules in the M first radio frequency paths; and respectively carrying out radio frequency calibration in the preset period through the radio frequency modules in the M first radio frequency paths based on the detection voltages corresponding to the M first radio frequency paths.

In one possible implementation, each of the K rf paths further includes an antenna; the receiving, through the N second radio frequency paths, corresponding service data and sending a service in the preset period respectively includes: respectively acquiring the corresponding service data through the physical protocol processing modules in the N second radio frequency channels, and forming a service frame based on the corresponding service data; performing signal modulation on the service frame through the radio frequency modules in the N second radio frequency channels respectively to obtain second radio frequency signals of the N second radio frequency channels respectively; respectively performing power amplification on the second radio frequency signals through the respective power amplifiers in the N second radio frequency paths to obtain the amplified second radio frequency signals of the N second radio frequency paths; and sending the amplified second radio frequency signals of the N second radio frequency channels to an air interface within the preset period through respective antennas of the N second radio frequency channels.

In one possible implementation, the radio frequency calibration includes power calibration of a radio frequency signal; the performing, by the radio frequency modules in the M first radio frequency paths, radio frequency calibration respectively based on the detection voltages corresponding to the M first radio frequency paths includes: and respectively calibrating the power of the radio frequency signal through the radio frequency modules in the M first radio frequency channels based on the detection voltage and the preset range corresponding to the M first radio frequency channels.

In one possible implementation, the antenna is connected to the output terminal of the power amplifier through a switching circuit, and the switching circuit includes a plurality of switches; when the radio frequency path is the first radio frequency path, each switch in the plurality of switches is in a disconnected state, and is used for disconnecting a connection circuit between the power amplifier and the antenna, so as to obtain the detection voltage through the diode, and transmit the detection voltage back to the radio frequency module; and when the radio frequency path is the second radio frequency path, each switch of the plurality of sequentially connected switches is in a closed state, and is used for conducting the power amplifier and the connection circuit of the antenna so as to send the amplified second radio frequency signal to an air interface through the antenna.

The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

As used in this specification, the terms "component," "module," "system," and the like are intended to refer to a computer-related entity, either hardware, firmware, a combination of hardware and software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a processor and the processor can be a component.

First, some terms in the present application are explained to facilitate understanding by those skilled in the art.

(1) Radio Frequency (RF), which represents an electromagnetic Frequency that can be radiated into space, ranges from 300KHz to 30 GHz. Radio frequency is referred to as RF, which is radio frequency current, and is a short term for high frequency alternating current variable electromagnetic waves. Alternating current that changes less than 1000 times per second is called low frequency current, alternating current that changes more than 10000 times per second is called high frequency current, and radio frequency is such a high frequency current. The cable television system adopts a radio frequency transmission mode. In the theory of electronics, current flows through a conductor, and a magnetic field is formed around the conductor; an alternating current passes through a conductor, around which an alternating electromagnetic field, called an electromagnetic wave, is formed. When the frequency of the electromagnetic waves is lower than 100KHz, the electromagnetic waves can be absorbed by the earth surface and cannot form effective transmission, but when the frequency of the electromagnetic waves is higher than 10KHz, the electromagnetic waves can be transmitted in the air and reflected by an ionosphere at the outer edge of the atmosphere to form long-distance transmission capability, the high-frequency electromagnetic waves with the long-distance transmission capability are called radio frequency, and the radio frequency technology is widely used in the field of wireless communication.

(2) A Multiple-Input Multiple-Output (MIMO) technology is a technology that uses Multiple transmitting antennas and Multiple receiving antennas at a transmitting end and a receiving end, respectively, so that signals are transmitted and received through the Multiple antennas at the transmitting end and the receiving end, thereby improving communication quality. The multi-antenna multi-transmission multi-reception mobile communication system can fully utilize space resources, realizes multi-transmission and multi-reception through a plurality of antennas, can improve the system channel capacity by times under the condition of not increasing frequency spectrum resources and antenna transmitting power, shows obvious advantages, and is regarded as the core technology of next generation mobile communication.

Referring to fig. 1, fig. 1 is a schematic diagram of a wireless communication network according to the prior art according to an embodiment of the present invention. As shown in fig. 1, the wireless communication network may include a wireless Access Point (AP) and a plurality of terminal devices, and specifically may include terminal device 200-1 and terminal device 200-2 … shown in fig. 1, where Z may be an integer greater than or equal to 3. The AP is a creator and a manager of a wireless communication network, and all terminal devices (or referred to as workstations (STAs)) may establish communication links with the AP respectively, and access the network through the AP and perform communication. Alternatively, the communication between the terminal devices may be forwarded through the AP, for example, when the terminal device 200-1 (for example, a laptop in fig. 1) is to communicate with the terminal device 200-2 (for example, a smartphone in fig. 1), the link that passes through may include the terminal device 200-1, the AP, and the terminal device 200-2. An AP and all terminal devices connected to it form a Base Station Subsystem (BSS), and all devices in the system can communicate through the AP. Alternatively, a plurality of APs may set the same BSS Identity (ID) and connect through a Distribution System (DS), and all terminal devices that establish communication links with the plurality of APs may communicate through the plurality of APs at this time. As described above, optionally, the AP may be a Wireless device having the above functions (for example, including a Wireless communication function, etc.), and further, the Wireless device may be a Wireless router having the above functions, a smart phone (for example, a smart phone that opens a Wireless-Fidelity (WIFI) hotspot), a wearable smart device, a tablet computer, a notebook computer, a desktop computer, a computer system composed of multiple computers, and so on. Optionally, the terminal device may be a smart phone, a wearable smart device, a tablet computer, a notebook computer, a desktop computer, and the like, which have the above functions (for example, including a wireless communication function, and the like), and this is not particularly limited in this embodiment of the present invention.

In the conventional wireless communication technology, radio frequency is an important part for implementing wireless communication, please refer to fig. 2, and fig. 2 is a schematic circuit structure diagram of a wireless chip in the prior art according to an embodiment of the present invention. As shown in fig. 2, the circuit may simply consist of a transmitting path and a receiving path, or may be divided into 4 parts, such as a digital baseband signal processing module, a radio frequency module, an analog front end, and an antenna, according to module division. Optionally, the circuit may be applied to the wireless device (i.e., AP) and may also be applied to the terminal device (i.e., STA), which is not specifically limited in this embodiment of the present invention. As shown In fig. 2, on the rf transmitting side, the Digital baseband signal processing module outputs two In-phase/Quadrature (I/O) baseband signals, the two I/O baseband signals are processed by a Digital-to-Analog (D/a) converter and a Low Pass Filter (LPF), modulated by a modulator (for example, an I/Q modulator, which may include a Mixer (Mixer)1, a Mixer 2, a 0 ° synthesizer 3, etc. as shown In fig. 2), and upconverted In the Mixer 1 and the Mixer 2. Because the phases of the local oscillation signals of the mixer 1 and the mixer 2 are different by 90 °, the output signals of the mixer 1 and the mixer 2 are orthogonal, and the two orthogonal signals are vector-synthesized in the 0 ° synthesizer 3 shown in fig. 2, thereby outputting a radio frequency signal (i.e., the two I/O baseband signals are modulated into a radio frequency signal via the modulator). Then, the radio frequency signal passes through a Band Pass Filter (BPF) 4, a mixer 5, a band pass Filter 6, and a Power Amplifier (PA) in this order, and is transmitted through an antenna switch (Transmitter and Receiver, T/R) and a radio frequency RF antenna. Further, other devices (which may include, for example, terminal device 200-1, terminal device 200-2 …, terminal device 200-Z, and other wireless devices of fig. 1, etc.) may receive the radio frequency signal via respective antennas to enable wireless communication between the devices. On the RF receiving side, the RF antenna may receive an RF signal transmitted by another device, the RF signal sequentially passes through the band pass filter 7, the Low Noise Amplifier (LNA), the mixer 8 and the band pass filter 9, and is demodulated by a demodulator (for example, an I/Q demodulator, which may include the mixer 10 and the mixer 11 shown in fig. 2), the RF signal is down-converted in the mixer 10 and the mixer 11, and an I/O two-way baseband signal is output. The two paths of I/O baseband signals are respectively transmitted to a digital baseband signal processing module after passing through a low-pass filter, an Amplifier (AMP) and an Analog/digital (A/D) converter, so that wireless communication between devices is completed. In some possible embodiments, the circuit may have more or fewer, or even different, components and structures than those shown in fig. 2, which are not specifically limited by the embodiments of the present invention.

The rf device (e.g., may include an rf module in the circuit shown in fig. 2) is an important component of the wireless device, and carries important functions related to wireless communication (e.g., including the above-mentioned conversion function of digital baseband signals and rf signals, etc.). However, due to differences in processes, component performance, and the like of the rf devices, the performance of the rf path of each wireless device (or referred to as WIFI device, which may include, for example, a wireless router and a smart phone for home use, etc.) often has different differences. Also, the difference may degrade the quality of the signal transmitted by the wireless device (e.g., the transmission power of the rf signal for the wireless device is low, causing the signal to be received by other devices, etc.), the demodulation capability, and so on. In addition, the rf device is also susceptible to external environment, such as temperature, etc., which may also degrade the quality and demodulation capability of the signal transmitted by the wireless device. Therefore, in order to compensate for the differences of the rf devices and the changes of the external environment, most wireless devices using the rf devices introduce an rf calibration procedure. The radio frequency calibration procedure may include radio frequency transmission direction calibration and radio frequency reception direction calibration, where the radio frequency transmission direction calibration may measure an offset of a radio frequency transmission link and perform difference compensation by transmitting calibration data (or referred to as a calibration data sequence) through the wireless device, and the reception direction calibration may measure an offset of a radio frequency transmission link and perform difference compensation by receiving air interface data through the wireless device.

First, in order to facilitate understanding of the embodiments of the present invention, technical problems to be specifically solved by the present application are further analyzed and presented. In the prior art, radio frequency calibration technology for wireless devices includes various schemes, and the following exemplary lists one scheme commonly used as follows.

Referring to fig. 3, fig. 3 is a schematic diagram of a radio frequency calibration in the prior art according to an embodiment of the present invention. As shown in fig. 3, the wireless device may be a wireless router (or referred to as a gateway device), and the wireless device may be a wireless access point AP, and the terminal device 200-1, the terminal device 200-2 …, the terminal device 200-Z, and so on shown in fig. 3 may access the network through the wireless device for communication. The wireless device has two radio paths (e.g., radio path 1 and radio path 2 shown in fig. 3). It should be noted that, in the existing MIMO technology, generally, a wireless device may have two or more radio frequency paths, and a signal frequency band of each radio frequency path may be different, for example, may be 2.4GHZ and 5GHZ, and this is not limited in this embodiment of the present invention. The prior art rf calibration technique is described herein in terms of a wireless device having two rf paths as shown in fig. 3. As shown in fig. 3, the wireless device may include a Medium Access Control (MAC) (or may be referred to as a Medium Control module, etc.), and an rf path 1 and an rf path 2 respectively connected to the MAC. The RF paths 1 and 2 may have the same structure, and the RF path 1 may specifically include a Physical Layer (PHY) (or referred to as a Physical protocol processing module) as shown in fig. 3, an RF module RF, a power amplifier PA, a diode d (diode), a low noise amplifier LNA, a switch 1 (e.g., a single-pole multi-throw switch shown in fig. 3), and an antenna 1. As shown in fig. 3, the PHY may be disposed outside the RF path and connected to the RF module RF in the RF path, the RF module RF is connected to the input end of the power amplifier PA, and the connection channel between the RF module RF and the power amplifier PA may be the RF transmission channel TX. The input end of the diode D is connected with the power amplifier PA, and the output end of the diode D is connected with the radio frequency module RF to form a calibration loop. The output of the power amplifier PA may be connected to the antenna 1 through the switch 1, for example, when the switch 1 is placed at the position 11, the circuit between the power amplifier PA and the antenna 1 is turned on, and the signal of the radio frequency path 1 may be sent to the air interface through the antenna 1. When the switch 1 is placed at the position 12, the position 13 or the position 14, the circuit between the power amplifier PA and the antenna 1 is disconnected, and at this time, the signal of the radio frequency path 1 cannot be transmitted to the air interface through the antenna 1. Alternatively, as shown in fig. 3, the output terminal of the low noise amplifier LNA is connected to the radio frequency module RF, and the connection channel between the radio frequency module RF and the low noise amplifier LNA may be a radio frequency receiving channel RX. The input end of the low noise amplifier LNA can be connected to the antenna 1 through the switch 1, for example, when the switch 1 is placed at the position 12, a circuit between the low noise amplifier LNA and the antenna 1 is turned on, a signal in an air interface (for example, a signal sent by another device) can be received through the antenna 1, and the signal is transmitted to the low noise amplifier LNA for power amplification, and then the amplified signal is transmitted to the radio frequency module RF through the radio frequency receiving channel RX for a subsequent series of signal processing and the like. When the switch 1 is placed in the position 11 or the position 14, the circuit between the low noise amplifier LNA and the antenna 1 is disconnected, and at this time, the signal received by the antenna 1 cannot be transmitted to the low noise amplifier LNA for power amplification, and a subsequent series of signal processing and the like are performed. Optionally, when the power of the signal received by the antenna 1 is larger or is within a normal power range in which the radio frequency module RF can perform signal processing (that is, the received signal does not need to be power-amplified by the low noise amplifier LNA), the switch 1 may be placed at the position 13, the connection circuit between the antenna 1 and the radio frequency module RF is turned on, and the signal received by the antenna 1 is transmitted to the radio frequency module RF for a subsequent series of signal processing without passing through the low noise amplifier LNA. The radio frequency path 2 may specifically comprise a PHY, a radio frequency module RF, a power amplifier PA, a diode D, a low noise amplifier LNA, a switch 2 (e.g. a single pole multiple throw switch as shown in fig. 3) and an antenna 2 as shown in fig. 3. Optionally, the composition and connection relationship of each part in the radio frequency path 2 may be the same as those of each part in the radio frequency path 1, and will not be described herein again.

In the prior art, the radio frequency calibration scheme for the transmission direction of the wireless device is generally: and performing radio frequency calibration on all radio frequency paths in the wireless equipment one by one until all radio frequency paths are calibrated. Taking the rf calibration performed by the rf path 1 in fig. 3 as an example, the conventional rf calibration technique may specifically include the following steps s 11-s 13:

step s11, the wireless device contends for the air interface sending right, and sends a cts-self frame to the air interface.

Specifically, the wireless device contends for an air interface transmission right before the radio frequency calibration, and after contending for the air interface transmission right, may send a cts-self frame to the air interface to notify other devices (for example, the terminal device 200-1, the terminal device 200-2 …, the terminal device 200-Z, and other wireless devices shown in fig. 3, and the like) that the wireless device has acquired the air interface transmission right, and notify other devices that data is not to be sent to the air interface during the period (for example, other devices do not perform service transmission during the period), so as to reduce interference of other devices to the wireless device, and ensure accuracy of the radio frequency calibration of the wireless device, and the like. It should be noted that, the conventional wireless communication generally adopts Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) technology, and before sending data (for example, service transmission or radio frequency calibration, etc.), a wireless device will first check whether a spatial wireless link is in an idle state (for example, whether an air interface is occupied, etc.), and in order To avoid Collision of data transmission among Multiple wireless devices, when a wireless device occupies a wireless link (i.e., contends for an air interface transmission right), a CTS-self frame will be sent first, or a Clear To Send/request To Send (CTS/RTS) frame is sent To notify other devices.

Step s12, a calibration loop for the wireless device is set.

Specifically, as shown in fig. 3, when the radio frequency path 1 performs radio frequency calibration, the switch 1 may be placed at a position 14 to disconnect the connection circuit between the power amplifier PA and the antenna 1, to ensure that a signal of the radio frequency path 1 cannot be sent to an air interface through the antenna 1 (i.e., to ensure that a signal generated when the radio frequency path 1 performs radio frequency calibration does not leak to the air interface), and to ensure that the radio frequency module RF may receive data (e.g., a detection Voltage (VDET) shown in fig. 3) returned by the diode through the calibration loop (e.g., a calibration loop composed of the power amplifier PA, the diode D, and the radio frequency module RF shown in fig. 3) and perform radio frequency calibration. For example, the RF module RF may perform power calibration of an RF model according to the detection voltage, and the like. Optionally, the calibration loop may be a VDET loop as shown in fig. 3 (for example, a calibration loop including the power amplifier PA, the diode D, and the radio frequency module RF as shown in fig. 3), may also be an air interface loop, may also be another calibration loop, may have more or fewer components than those shown in fig. 3, or may even be different components, and optionally, may set a different standard loop to complete different radio frequency calibrations, which is not specifically limited in this embodiment of the present invention.

Step s13, calibration data is sent to the rf path 1, and rf calibration is performed.

Specifically, the MAC generates calibration data for radio frequency calibration and transmits the calibration data to the radio frequency path 1, wherein the PHY in the radio frequency path 1 receives the calibration data and composes a calibration frame, and then transmits the calibration frame to the radio frequency module RF. The radio frequency module RF performs signal modulation based on the calibration frame to obtain a radio frequency calibration signal, and then the radio frequency calibration signal is amplified by the power amplifier, and a detection voltage corresponding to the radio frequency calibration signal after power amplification is obtained through the diode D in the calibration loopback and is transmitted back to the radio frequency module. The final rf module may perform rf calibration according to the detection voltage (e.g., may perform power calibration of the rf signal according to the detection voltage and a preset range, such as power detection and power compensation, etc.). It should be noted that, in the prior art, during the period of performing the radio frequency calibration on the radio frequency path 1, the MAC cannot generate the service data, that is, the radio frequency path 2 cannot be used for performing the service transmission, that is, the radio frequency path 2 is in an idle state, which causes a waste of resources of the radio frequency path in the wireless device. Moreover, the more radio frequency paths that the wireless device has, the more idle radio frequency paths are during the calibration of a certain radio frequency path, which greatly reduces the utilization rate of the radio frequency paths and the utilization rate of air interfaces.

The steps involved in the rf calibration of the rf path 2 refer to the steps s 11-s 13 involved in the rf calibration of the rf path 1, which are not described herein again.

As described above, in the conventional radio frequency calibration scheme, when one radio frequency path in a wireless device is performing radio frequency calibration, other radio frequency paths of the wireless device cannot perform normal service transmission, and due to a connection error of a switch (for example, when the radio frequency path 1 performs radio frequency calibration, the switch 1 should be placed at the position 14, but due to misoperation or switch damage, etc., the switch 1 is placed at the position 11), a signal generated by the radio frequency calibration (for example, the radio frequency calibration signal output after being amplified by the power amplifier) is likely to leak to an air interface, thereby causing interference to service transmission of other devices. However, in the prior art, to avoid interference of the radio frequency calibration on the service transmission of other devices (or interference of the service transmission of other devices on the radio frequency calibration of the wireless device, etc.), it is often selected to transmit a cts-self frame, so that during the radio frequency calibration of the wireless device, other devices do not act and do not perform service transmission (that is, in the prior art, the radio frequency calibration may block normal service transmission). Obviously, the existing radio frequency calibration scheme greatly reduces the utilization rate of an air interface and the throughput of the whole wireless service, and influences the internet experience of a user and the like.

Therefore, in order to solve the problem that the actual requirement is not met in the current radio frequency calibration related technology, the technical problem to be solved in practice in the present application includes the following aspects: when one or more radio frequency channels of the wireless equipment carry out radio frequency calibration, other channels of the wireless equipment can still carry out service transmission; and reducing the leakage of signals generated by radio frequency calibration to an air interface.

The wireless device 100a may be a wireless router, a home gateway, a computer, or the like having the above-described functions, which is not particularly limited in the embodiment of the present invention.

Referring to fig. 6, fig. 6 is a schematic diagram illustrating radio frequency calibration of a wireless device according to an embodiment of the present invention, as shown in fig. 6, the wireless device may be the wireless device 100a shown in fig. 4 or fig. 5, and the wireless device may include a wireless apparatus provided in the present application. The wireless device may include a media control module MAC (or referred to as a media access control layer) as shown in fig. 6 and K radio frequency paths (for example, radio frequency path 1 and radio frequency path 2, 2 radio frequency paths in fig. 6) connected to the MAC, where K is an integer greater than or equal to 1. Each radio frequency path may comprise a physical protocol processing module PHY (or referred to as physical layer), a radio frequency module RF, a power amplifier PA, a diode D, a low noise amplifier LNA, a switching circuit (e.g. switch 1 and switch 3 in radio frequency path 1 shown in fig. 6, where switch 1 and switch 3 are connected in series in turn, e.g. switch 2 and switch 4 in radio frequency path 2, where switch 2 and switch 4 are connected in series in turn), and an antenna (e.g. antenna 1 in radio frequency path 1 shown in fig. 6, where antenna 1 is connected to power amplifier PA via switch 1 and switch 3, and e.g. antenna 2 in radio frequency path 2, where antenna 2 is connected to power amplifier PA via switch 2 and switch 4). As shown in fig. 6, the PHY of each RF path may be disposed outside the RF path and RF-connected to the RF module in the RF path. Optionally, the structural composition of the wireless device and the connection relationship between the components may refer to the embodiment corresponding to fig. 3, which is not described herein again.

Referring to fig. 3 and fig. 6, the wireless apparatus in fig. 6 adds a separate rf calibration excitation unit in the MAC, and the rf calibration excitation unit can be used to generate M pieces of calibration data when M pieces of first rf paths of the wireless device need to be rf calibrated. Therefore, when the MAC generates M pieces of calibration data by the rf calibration driver (or during an intersecting time period), N pieces of traffic data for traffic transmission in N second rf paths of the wireless device may be generated by the original functional unit of the MAC (e.g., including the traffic transmission driver). That is, the MAC in the wireless device may be used to generate calibration data and traffic data simultaneously, ensuring that radio frequency calibration (e.g., including generation, framing, and transmission of calibration data, etc.) of the first radio frequency path does not affect traffic transmission (e.g., including generation, framing, and transmission of traffic data, etc.) of the second radio frequency path. Wherein M and N are integers greater than or equal to 1, and the sum of M and N is less than or equal to K. Alternatively, each of the M first rf paths may be an rf path for which rf calibration is not completed within a preset period (for example, a period taken for performing one round of rf calibration on each rf path in the wireless device), such as an rf path currently undergoing rf calibration, an rf path to be subjected to rf calibration, or the like. Each of the N second rf paths may be an rf path that has completed rf calibration in the preset period (i.e., an rf path that is not performing rf calibration, etc.). It is understood that the first rf path may be changed to the second rf path after the first rf path completes the rf calibration within the predetermined period. For example, when a new round of rf calibration is started, i.e. each rf path in the wireless device does not complete rf calibration in the preset period, each rf path may be referred to as a first rf path, and when the round of rf calibration is finished, i.e. each rf path in the wireless device completes rf calibration in the preset period, each rf path may be referred to as a second rf path. Obviously, each second rf path may be changed to the first rf path again when the next round of rf calibration arrives, and the process is repeated. For example, when performing radio frequency calibration on the radio frequency path 1 in fig. 6, the radio frequency path 1 may be a first radio frequency path, and the radio frequency path 1 may receive corresponding calibration data and perform radio frequency calibration in the preset period, and for example, when the radio frequency path 2 in fig. 6 completes radio frequency calibration in the preset period, the radio frequency path 2 may be a second radio frequency path, and the radio frequency path 2 may receive corresponding service data and perform service transmission in the preset period. Therefore, by the radio frequency calibration excitation unit added in the embodiment of the present invention, the MAC can generate service data while generating calibration data (or within an intersecting time period), so that when one or more radio frequency paths in the wireless device receive the calibration data and perform radio frequency calibration, other radio frequency paths of the wireless device can still receive the service data and perform service transmission, the capacity and space resources of the multiple radio frequency paths are fully utilized, and the utilization rate of an air interface and the throughput of wireless services are improved.

Referring to fig. 3 and fig. 6, the power amplifier and the antenna in each rf path are connected by a switch circuit, and it is obvious that the wireless device in fig. 6 adds a first-stage switch on the basis of the original switch circuit shown in fig. 3, for example, the rf path 1 adds a switch 3 on the basis of the original switch 1, and for example, the rf path 2 adds a switch 4 on the basis of the original switch 2. The switches 1, 2, 3 and 4 may be single pole, multiple throw switches as shown in fig. 6. Therefore, the isolation between the wireless device and the air interface can be further increased through the added primary switch, and the signal generated during radio frequency calibration is more effectively prevented from leaking to the air interface, so that the interference of the leaked signal on the service transmission of other equipment is reduced, meanwhile, the influence of the signal in the air interface (such as the signal transmitted by other equipment) on the radio frequency calibration of the wireless equipment can be isolated, and the accuracy of the radio frequency calibration is improved. For example, when the radio frequency calibration is performed on the radio frequency path 1, the switch 1 may be placed at the position 11 due to a misoperation or switch damage, and the like, but the switch 3 is placed at the position 32, so that the connection circuit between the power amplifier PA and the antenna 1 can still be isolated by the switch 3, a signal generated when the radio frequency calibration is performed on the radio frequency path 1 is prevented from leaking to an air interface through the antenna, and the signal in the air interface can also be prevented from affecting the radio frequency calibration of the radio frequency path 1. Optionally, in some possible embodiments, the switch circuit may further include more switches than those shown in fig. 6, which is not particularly limited by the embodiments of the present invention.

For example, the rf calibration of the wireless device may be a periodic calibration, such as a round of rf calibration for each rf path (e.g., rf path 1 and rf path 2) of the wireless device every 1000 traffic frames. As shown in fig. 6, when the radio frequency path 1 needs to perform radio frequency calibration, and the radio frequency path 2 completes the radio frequency calibration in the period, the MAC may generate a calibration data and a service data, and may also generate a calibration data and a plurality of service data, where the plurality of service data may be used for a subsequent series of service transmissions after the radio frequency path 1 completes the current radio frequency calibration, or after the radio frequency path 2 completes the current service transmission, and the like, which is not specifically limited in this embodiment of the present invention. The MAC may send the calibration data to rf path 1 and the traffic data to rf path 2, respectively. Alternatively, as shown in fig. 6, in the radio frequency path 1, the PHY is configured to receive the calibration data, compose a calibration frame based on the calibration data, and then transmit the calibration frame to the radio frequency module RF; the radio frequency module RF is used for receiving the calibration frame, modulating signals based on the calibration frame and outputting a first radio frequency signal to the power amplifier PA; the power amplifier PA is used for power amplifying the first radio frequency signal. In the radio frequency path 1, the switch 1 is placed at the position 14, and the switch 3 is placed at the position 32, and is used for cutting off a connection circuit between the power amplifier PA and the antenna 1, so that the amplified first radio frequency signal output by the power amplifier cannot be sent to an air interface through the antenna 1, and a detection voltage corresponding to the amplified first radio frequency signal is obtained through a diode D in a calibration loop as shown in fig. 6, and the detection voltage is transmitted back to the radio frequency module RF. The RF module RF may then perform RF calibration (e.g., may include detecting RF power of the amplified first RF signal based on the detection voltage, performing power compensation based on the detected power and a preset power range, etc.) based on the detection voltage and a preset range (e.g., may be an optimal power range of the RF signal of the wireless device). Optionally, the radio frequency calibration may also include calibration of a center frequency of the radio frequency path, and so on, which are not described herein again. In general, when rf calibration of rf path 1 is required, switch 1 may be set to position 14 and switch 3 may be set to position 32 to disconnect the connection circuit between power amplifier PA and antenna 1 by logic level control before rf path 1 receives the calibration data or before MAC generates the calibration data. Alternatively, as shown in fig. 6, in the radio frequency path 2, the PHY is configured to receive the service data, compose a service frame based on the service data, and then transmit the service frame to the radio frequency module RF; the radio frequency module RF is used for receiving the service frame, modulating signals based on the service frame and then outputting a second radio frequency signal to the power amplifier PA; the power amplifier PA is used for power amplifying the second radio frequency signal. In the radio frequency path 2, the switch 2 is placed at the position 21, and the switch 4 is placed at the position 41, so as to turn on a connection circuit between the power amplifier PA and the antenna 2, and ensure that the amplified second radio frequency signal output by the power amplifier PA is sent to an air interface through the antenna 2, so as to complete service transmission, for example, service transmission may be performed on the terminal device 200-1 shown in fig. 6, and so on. For another example, if the wireless device has 3 radio frequency paths, when one of the radio frequency paths performs radio frequency calibration, the other 2 radio frequency paths may respectively perform service transmission to different terminal devices (for example, the terminal device 200-1 and the terminal device 200-2 shown in fig. 6), and optionally, the 2 radio frequency paths may also perform service reception, and the like.

Referring to fig. 7, fig. 7 is a schematic diagram of radio frequency calibration of another wireless device according to an embodiment of the present invention. As shown in fig. 7, in some possible embodiments, the wireless device may virtualize a user through a Multiple-Input Multiple-Output technology (e.g., a downlink Multiple-Input Multiple-Output (DL-MIMO)) of WIFI without adding an independent rf calibration unit, and the virtual user may generate and transmit calibration data to a corresponding rf path (i.e., an rf path that needs to be rf calibrated, such as the first rf path described above) and perform rf calibration while generating and transmitting service data through a MAC and performing service transmission. Therefore, simultaneous transmission of the radio frequency calibration data and the service data can be achieved (for example, there may be an overlapping portion between a time period for transmitting the radio frequency calibration data and a time period for transmitting the service data, and the like), and while performing radio frequency calibration on one or more radio frequency paths of the wireless device, other radio frequency paths of the wireless device can perform service transmission (for example, there may be an overlapping portion between a time period for performing radio frequency calibration on the one or more radio frequency paths and a time period for performing service transmission on the other radio frequency paths, and the like). For example, as shown in fig. 7, when the rf path 1 needs to perform rf calibration, the virtual user may be placed on the rf path 1 to transmit calibration data, and the rf path 1 receives the calibration data and performs rf calibration; during this period, the rf path 2 may receive the service data transmitted by the MAC, perform service transceiving, and the like. In some possible embodiments, the simultaneous generation of the calibration data and the service data, the simultaneous execution of the radio frequency calibration and the service transmission, and the like may also be implemented by other methods or by adding other functional units, which is not particularly limited in this embodiment of the present invention.

As shown in fig. 6 and 7, because a first-stage switch (for example, the added switch 3 and the added switch 4) is added to each rf path, when performing rf calibration, the wireless device and the air interface may be effectively isolated, that is, a signal generated by the rf calibration (for example, the first rf signal output by the power amplifier PA after amplification) may be effectively prevented from leaking to the air interface, so that the leaked signal is prevented from blocking the air interface and interfering with service transmission of other devices. Meanwhile, the interference of signals in the air interface to the radio frequency calibration of the wireless equipment can be effectively prevented, and the accuracy of the radio frequency calibration is ensured. Therefore, when the wireless device needs to perform radio frequency calibration, the cts-self frame does not need to be sent again, and the air interface sending right is contended, so that it is ensured that other devices can still perform service receiving and sending and the like (for example, including service receiving, service sending and the like) when the wireless device performs radio frequency calibration, and the air interface utilization rate and the throughput of the wireless service are improved. For example, a wireless device with 4 antennas (i.e., 4 rf paths) may need to perform one round of rf calibration for periodic calibration, e.g., every 100 frames of traffic are transmitted. In general, each antenna in the wireless device needs to calibrate 2 gears, and the calibration of each gear needs to occupy one calibration frame, so each calibration cycle needs to occupy 8 calibration frames, that is, the overhead of each calibration cycle occupies 8% of the traffic. In general, a wireless device with 4 antennas has a throughput of 4.9Gbps in a scenario of 802.11ax and 160MHz, and a gain of 6% is expected.

Scene two: referring to fig. 8, fig. 8 is a schematic view of another application scenario provided in the embodiment of the present invention. As shown in fig. 8, the application scenario may include the wireless device 100b and a plurality of terminal devices, and specifically may include the terminal device 200-1 and the terminal device 200-2 …, and the terminal device 200-Z. The wireless device 100b may be a wireless access point AP, and the terminal device 200-1, the terminal device 200-2 …, the terminal device 200-Z, and the like may access the network through the wireless device 100a to perform communication. For example, as shown in fig. 8, the wireless device may be a smart phone that can provide wireless services to devices connected thereto (e.g., terminal device 200-1, terminal device 200-2 …, terminal device 200-Z shown in fig. 8) by turning on a WIFI hotspot.

Referring to fig. 9, fig. 9 is a functional block diagram of another wireless device according to an embodiment of the present invention. The following describes an embodiment of the wireless device 100 b.
