[0037] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.
[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.
[0039] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.
[0040] It should also be pointed out that the terms "first\second\third" involved in the embodiments of the present application are only used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.
[0041] In the embodiments of the present application, the term "and / or" is merely a description of the association relationship between associated objects, indicating that three relationships may exist. For example, object A and / or object B may represent three situations: object A exists alone, object A and object B exist at the same time, and object B exists alone.
[0042] In addition, in the embodiments of the present application, “plurality” means two or more than two, unless otherwise clearly and specifically defined.
[0043] At the same distance, the strength of the signal radiated (or received) by the antenna in different directions is different, so the antenna has directivity. The directivity of an antenna refers to the relationship between the amplitude of the electric field strength of the signal radiated (or received) by the antenna and the spatial direction. Usually, the directivity coefficient D is used to represent the directivity index of an antenna.
[0044] The definition of the directivity coefficient D of an antenna is the radiated power flux density s of the antenna in the direction of maximum radiation at the same distance and the same radiated power. max (or the square of the maximum field strength, |E Max | 2 ) and the radiated power flux density S of a non-directional antenna (i.e., an omnidirectional antenna) i (or the square of the field strength, |E i | 2 ), the specific formula is as follows:
[0045]
[0046] In the above formula, P S is the actual antenna radiation power, P Siis the radiated power of the non-directional antenna.
[0047] It can be seen from the above formula that when the radiation power is constant, since the isotropic antenna will dissipate part of its energy to the surroundings, in the direction of maximum radiation (i.e., the main lobe), the radiation power of the directional antenna is D times higher than that of the isotropic antenna.
[0048] The antenna of the mobile device is a non-directional antenna. When the antenna is working, it basically transmits signals uniformly in the shape of a hemisphere, resulting in poor signal directionality. Since the signal emitted by the mobile device has poor directionality, part of the transmitted energy will be wasted, making it impossible for the mobile device to achieve uplink communication in a weak signal environment, and even unable to connect to the cellular network. To this end, the following technical solutions of the embodiments of the present application are proposed.
[0049] It should be noted that, although the above description is explained with reference to a “mobile device”, the technical solution of the embodiment of the present application is not limited thereto. The technical solution of the embodiment of the present application can be applied to any type of terminal. For example, the terminal can be: an Internet of Things (IoT) device, a satellite terminal, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with a wireless communication function, a computing device or other processing device connected to a wireless modem, a server, a mobile phone, a tablet computer (Pad), a computer with a wireless transceiver function, a PDA, a desktop computer, a personal digital assistant, a portable media player, a smart speaker, a navigation device, a smart watch, a smart glasses, a smart necklace and other wearable devices, a pedometer, a digital TV, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a transportation safety (transportation) system, a wireless communication terminal in a smart grid, a wireless communication terminal in a smart home ... Safety), wireless terminals in smart cities, wireless terminals in smart homes, and vehicles, vehicle-mounted devices, vehicle-mounted modules, wireless modems, handheld devices, customer premises equipment (CPE), smart home appliances, etc. in the Internet of Vehicles system. In some implementations, the "terminal" described in the embodiments of the present application may be a mobile device.
[0050] Beamforming technology can greatly enhance the directivity of antennas. Its physical principle is: the superposition of two signals with the same frequency strengthens the vibration of signals in some areas and weakens the vibration of signals in other areas, and the areas with strengthened vibration and weakened vibration are separated from each other. If the peaks of the two signals meet, or the troughs meet, the vibrations of the signals are added together, the peaks of the signals are higher, and the troughs are deeper. This is called constructive interference. On the contrary, if the peaks and troughs of the two signals meet, the vibrations of the signals cancel each other out. This is called destructive interference.
[0051] Due to volume layout restrictions, beamforming technology is only applied to base stations. Figure 1The beamforming technology applied by the base station implements a downlink signal with a specific direction based on an antenna array, and performs downlink communication with the terminal through the downlink signal in the specific direction. However, the beamforming technology applied on the base station is based on the antenna array, which has the disadvantages of large size and high cost and cannot be directly applied to the terminal. To this end, the technical solution of the embodiment of the present application proposes a beamforming technology suitable for the terminal, which can enhance the directionality of the uplink signal based on the existing antenna of the terminal and improve the uplink communication capability of the terminal.
[0052] Figure 2 is a flow chart of a signal processing method provided in an embodiment of the present application, and the signal processing method is applied to a terminal, such as Figure 2 As shown, the signal processing method comprises the following steps:
[0053] Step 201: Generate a first signal having a first phase and a second signal having a second phase based on a target signal, wherein the first phase and the second phase are the same.
[0054] Here, the terminal has a radio frequency transceiver (referred to as a transceiver for short), and the terminal generates a target signal through the transceiver, and the target signal is an uplink signal to be sent to the network device.
[0055] Here, the terminal has a communication module, and the terminal generates a first signal with a first phase and a second signal with a second phase based on a target signal through the communication module, and the first phase and the second phase are the same. The first signal and the second signal are the same two signals, and the sameness here is reflected in one or more of the following aspects: the frequency of the signal is the same, the information carried by the signal is the same, the phase of the signal is the same, and the power of the signal is the same.
[0056] In an embodiment of the present application, a first signal having a first phase and a second signal having a second phase are generated based on a target signal. This can be achieved by using analog beamforming technology, or by using digital beamforming technology, or by using hybrid beamforming technology, which is described below.
[0057] Solution 1: Analog beamforming technology
[0058] In some embodiments, a first signal and a second signal are generated based on a target signal; the first signal is transmitted to a first phase shifter through a first RF front-end link, and the second signal is transmitted to a second phase shifter through a second RF front-end link; the phase of the first signal is adjusted to a first phase through the first phase shifter, and the phase of the second signal is adjusted to a second phase through the second phase shifter.
[0059] Here, the first RF front-end link, the first phase shifter, the second RF front-end link and the second phase shifter are analog devices, so the beamforming achieved by these devices is called analog beamforming. Among them, the RF front-end link (such as the first RF front-end link and the second RF front-end link) includes: a power amplifier (PA), a low noise amplifier (LNA), and optionally, also includes: a filter, a duplexer, an antenna switch and other devices. Among them, the PA is used to amplify the RF signal of the transmission channel, and the LNA is used to amplify the RF signal of the receiving channel. The filter is used to retain the signal within a specific frequency band and filter out the signal outside the specific frequency band; the duplexer is used to isolate the transmission signal and the reception signal to ensure that the reception and transmission can work normally when sharing the same antenna; the antenna switch is used to switch the reception and transmission of the RF signal, and switch the components of different frequency bands. The phase shifter (such as the first phase shifter and the second phase shifter) is used to adjust the phase of the signal.
[0060] In one example, if Figure 3 As shown, the transceiver generates two identical signals, referred to as the first signal and the second signal. The transceiver transmits the first signal to the first RF front-end link, processes it accordingly through the first RF front-end link, and transmits it to the first phase shifter, and adjusts the phase of the first signal to the first phase through the first phase shifter; and the transceiver transmits the second signal to the second RF front-end link, processes it accordingly through the second RF front-end link, and transmits it to the second phase shifter, and adjusts the phase of the second signal to the second phase through the second phase shifter. Here, the processing of the signal by the RF front-end link (such as the first RF front-end link and the second RF front-end link) is related to the devices included in the RF front-end link. For example, the RF front-end link at least includes a PA, then the processing of the signal by the RF front-end link at least includes a signal amplification processing. For the first RF front-end link and the second RF front-end link, the first signal and the second signal are amplified with equal amplitudes, respectively. Furthermore, the terminal transmits the first signal with the first phase through the first antenna, and transmits the second signal with the second phase through the second antenna of the terminal. In this way, the first signal with the first phase and the second signal with the second phase can be spatially coherent to form an uplink signal with a specific direction, and the uplink signal with a specific direction is transmitted to a network device (such as a base station), thereby realizing the use of analog beamforming technology to transmit the uplink signal to the network device through a beam in a specific direction.
[0061] Solution 2: Digital beamforming technology
[0062] In some implementations, a first signal having a first phase and a second signal having a second phase are generated based on a target signal and a beamforming matrix.
[0063] Here, the digital baseband generates a first signal with a first phase and a second signal with a second phase based on the target signal and the beamforming matrix. The digital baseband is a digital device, so the beamforming implemented by the device is called digital beamforming. The beamforming matrix can be preset, and the beamforming matrix can also be called a beamforming function, a mapping function, or a spatial filter.
[0064] In one example, if Figure 4 As shown, the transceiver generates a signal, which is called a target signal. The transceiver transmits the target signal to the digital baseband, and processes it accordingly through the digital baseband to obtain two signals with the same phase, namely: a first signal with a first phase and a second signal with a second phase, and the first phase and the second phase are the same. Further, the terminal transmits the first signal with the first phase through the first antenna, and transmits the second signal with the second phase through the second antenna of the terminal, so that the first signal with the first phase and the second signal with the second phase can be spatially coherent to form an uplink signal with a specific direction, and the uplink signal with a specific direction is transmitted to the network device (such as a base station), realizing the use of digital beamforming technology to transmit the uplink signal to the network device through a beam in a specific direction.
[0065] Solution 3: Hybrid Beamforming Technology
[0066] In some embodiments, a first signal having a third phase and a second signal having a fourth phase are generated based on a target signal and a beamforming matrix; the first signal having the third phase is transmitted to a first phase shifter through a first RF front-end link, and the second signal having the fourth phase is transmitted to a second phase shifter through a second RF front-end link; the phase of the first signal is adjusted from the third phase to the first phase through the first phase shifter, and the phase of the second signal is adjusted from the fourth phase to the second phase through the second phase shifter.
[0067] Here, the hybrid beamforming technology can be regarded as a combination of analog beamforming technology and digital beamforming technology. The analog beamforming technology part can refer to the description of the above-mentioned solution 1, and the digital beamforming technology part can refer to the description of the above-mentioned solution 2.
[0068] In one example, if Figure 5As shown, the transceiver generates a signal, which is called a target signal. The transceiver transmits the target signal to the digital baseband, and processes it accordingly through the digital baseband to obtain two signals, namely: a first signal with a third phase and a second signal with a fourth phase. The digital baseband transmits the first signal with the third phase to the first RF front-end link, and transmits it to the first phase shifter after corresponding processing through the first RF front-end link, and adjusts the phase of the first signal to the first phase through the first phase shifter; and the digital baseband transmits the second signal with the fourth phase to the second RF front-end link, and transmits it to the second phase shifter after corresponding processing through the second RF front-end link, and adjusts the phase of the second signal to the second phase through the second phase shifter. Here, the processing of the signal by the RF front-end link (such as the first RF front-end link and the second RF front-end link) is related to the devices included in the RF front-end link. For example, the RF front-end link at least includes a PA, then the processing of the signal by the RF front-end link at least includes a signal amplification processing. For the first RF front-end link and the second RF front-end link, the first signal and the second signal are amplified with equal amplitudes. Furthermore, the terminal transmits the first signal with the first phase through the first antenna, and transmits the second signal with the second phase through the second antenna of the terminal. In this way, the first signal with the first phase and the second signal with the second phase can be spatially coherent to form an uplink signal with a specific direction, and the uplink signal with a specific direction is transmitted to a network device (such as a base station), thereby realizing the use of hybrid beamforming technology to transmit the uplink signal to the network device through a beam in a specific direction.
[0069] Step 202: Transmit a first signal with a first phase through a first antenna of the terminal, and transmit a second signal with a second phase through a second antenna of the terminal; wherein the first signal with the first phase and the second signal with the second phase are spatially coherent to form an uplink signal with a specific direction.
[0070] In some implementations, before step 201, the following step is further included: detecting whether a beamforming function activation operation is obtained. If the beamforming function activation operation is detected, steps 201 and 202 are executed.
[0071] In one example, if Figure 6 As shown, the "settings" interface of the terminal provides a setting bar for the "beamforming" function, and the user can perform a selection operation to enable the beamforming function. In this way, the user can flexibly choose whether to enable the beamforming function according to their own needs.
[0072] In the above solution, the uplink signal in a specific direction needs to be directed toward the network device to ensure effective uplink communication between the terminal and the network device.
[0073] In some implementations, the user of the terminal can adjust the orientation of the terminal to the target orientation, so that the uplink signal is aligned with the network device. Specifically, the terminal receives the downlink signal sent by the network device, determines the location of the network device based on the downlink signal; based on the location of the network device, outputs prompt information, and the prompt information is used to guide the user of the terminal to adjust the orientation of the terminal to the target orientation; wherein, when the terminal is in the target orientation, the specific direction is the direction pointing to the network device.
[0074] Here, the terminal determines the location of the network device based on the downlink signal in the following ways, including but not limited to:
[0075] Method 1: The downlink signal carries the location information of the network device, and the terminal parses the downlink signal to obtain the location information of the network device.
[0076] Method 2: The downlink signal carries the identification information of the network device. The terminal parses the downlink signal to obtain the identification information of the network device, and obtains the location information of the network device by looking up the table according to the identification information of the network device.
[0077] Method 3: The terminal measures the signal quality of the downlink signal and infers the location information of the network device based on the signal quality of the downlink signal.
[0078] Method 4: The terminal measures the propagation time of the downlink signal and calculates the location information of the network device based on the propagation time of the downlink signal.
[0079] Here, the prompt information may be in any form, for example, the prompt information may be in the form of voice, picture, animation, text, etc.
[0080] In one example, if Figure 7 As shown, TX1 represents the first antenna, TX2 represents the second antenna, and after applying the beamforming technology in the embodiment of the present application, TX1 and TX2 radiate signals of the same phase (or the same amplitude), forming an uplink signal in a specific direction in space. After the terminal determines the location of the network device through the downlink signal sent by the network device, it guides the user to adjust the orientation of the terminal to the target orientation through prompt information, so that the uplink signal in a specific direction is aimed at the network device.
[0081] In some embodiments, the terminal has multiple antennas (more than 2 antennas), any two antennas among the multiple antennas can form a group of antennas, and the specific directions of the uplink signals formed by different groups of antennas are different. The terminal can select antennas to realize that the uplink signal is aligned with the network device. Specifically, the terminal receives the downlink signal sent by the network device, determines the location of the network device based on the downlink signal; based on the location of the network device, selects a group of antennas from the multiple antennas of the terminal as the first antenna and the second antenna; wherein the specific directions corresponding to the antennas of different groups are different, and the specific direction corresponding to the selected group of antennas is the direction pointing to the network device.
[0082] Here, the method for the terminal to determine the location of the network device based on the downlink signal can refer to the aforementioned related records.
[0083] In one example, if Figure 8 As shown, the terminal has 8 antennas (TX), a specific direction of the uplink signal formed by a group of antennas consisting of TX1 and TX2 is direction 1, a specific direction of the uplink signal formed by a group of antennas consisting of TX3 and TX4 is direction 2, a specific direction of the uplink signal formed by a group of antennas consisting of TX5 and TX6 is direction 3, and a specific direction of the uplink signal formed by a group of antennas consisting of TX7 and TX8 is direction 4. After the terminal determines the location of the network device through the downlink signal sent by the network device, it selects a group of antennas, such as TX3 and TX4, so that the uplink signal with direction 2 is aimed at the network device.
[0084] The above technical solution of the embodiment of the present application is further illustrated below in combination with specific application examples.
[0085] In this application example, a mobile phone is used as an example. Fig. 9 As shown in the figure, the communication architecture of the mobile phone consists of two parts, one is the 4G communication module, and the other is the 5G communication module. Among them, the 5G communication module supports 2 transmissions and 4 receptions (2Tx4Rx), 1 Tx corresponds to 1 PA, 1 Rx corresponds to 1 LNA, so the 5G communication module has 2 PAs and 4 LNAs. In a poor signal environment, the user turns on the beamforming function of the mobile phone, and the transceiver of the mobile phone sends two identical signals and transmits them to two RF front-end links and two phase shifters respectively. The two signals are power amplified in the RF front-end link and phase adjusted through the phase shifter to ensure that the signals emitted by the two antennas have the same power and the same phase. In this way, the mobile phone can transmit an uplink signal with a specific direction, enhance the uplink communication capability, and realize uplink communication in a weak signal environment.
[0086] The technical solution of the embodiment of the present application introduces a beamforming technology suitable for the terminal side, which uses the existing antenna of the terminal to form an uplink signal with a specific direction, thereby enhancing the terminal communication capability in weak signal scenarios and increasing the uplink communication capacity (ie, uplink throughput).
