Description

A signal processing method and related device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on July 31, 2023, with application number 202310959993.4 and invention name “A signal processing method and related equipment”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and in particular to a signal processing method and related equipment. Background Art

[0003] With the continuous evolution of wireless fidelity (WiFi) technology, the number of streams supported by the WiFi protocol continues to increase, the modulation order continues to rise, and the operating bandwidth remains unchanged. As a result, the maximum performance between access points (APs) and user devices often far exceeds actual user needs. However, WiFi performance can still be insufficient, leading to service lags and interruptions. This is primarily due to two reasons: 1. An insufficient number of APs / wireless routers, resulting in weak signal coverage in some areas; 2. User devices switching between different APs / wireless routers (terminal roaming) can cause long service interruptions during the switching process.

[0004] To this end, in a larger area (for example, an area larger than 100 square meters), there are usually three WiFi coverage solutions: Solution 1, access controller (AC) / cloud controller + thin AP (Fit AP); Solution 2, fat AP (Fat AP) / wireless router; Solution 3, mesh networking of fat AP / wireless router.

[0005] However, each node of these three solutions is a complete WiFi signal, which has high node cost and high power consumption. In addition, switching of user devices between different APs will cause service interruption.

[0006] Summary of the Invention

[0007] The embodiments of the present application provide a signal processing method and related equipment for achieving a larger coverage range while avoiding service termination and reducing power consumption.

[0008] The first aspect of the present application provides a signal processing method for a communication system, wherein the communication system includes an access point AP and N wireless units RU, where N is a positive integer greater than or equal to 2. In the present application, the AP generates a first signal, then performs power distribution on the first signal to obtain N first sub-signals, and sends the corresponding first sub-signal in the N first sub-signals to each RU in the N RUs through a transmission medium, and the N RUs and the N first sub-signals correspond one to one. Then, due to the coverage of the N RUs, the coverage range is larger, and there is only one AP, and the user equipment does not need to switch within the coverage range of the N RUs, so the service will not be interrupted, and compared with multiple APs, the power consumption is lower.

[0009] In some possible implementations, the AP may generate a baseband signal and, based on the baseband signal, generate a first channel signal and a second channel signal, wherein the first channel signal and the second channel signal have the same frequency band. Subsequently, the AP may perform frequency conversion on the first channel signal and the second channel signal respectively to obtain the first signal corresponding to the first channel signal and the second signal corresponding to the second channel signal, wherein the frequency band of the second signal is smaller than that of the second channel signal, and the frequency band of the first signal is smaller than that of the first channel signal. The AP may then perform power allocation on the second signal to obtain N second sub-signals, and transmit the corresponding second sub-signal of the N second sub-signals to each of the N RUs via a transmission medium. The N RUs correspond to the N second sub-signals in a one-to-one manner. By reducing the frequency band of the signal to be transmitted, the consumption of the transmission medium may be reduced.

[0010] In some possible implementations, the AP generates a baseband signal, generates a first channel signal and a second channel signal based on the baseband signal, the first channel signal and the second channel signal have the same frequency band, and performs frequency conversion on the first channel signal and the second channel signal respectively to obtain the first signal corresponding to the first channel signal and the second signal corresponding to the second channel signal, respectively, and the second signal and the first signal have different frequency bands.

[0011] Then, the AP can combine the first signal and the second signal to obtain a combined signal, and perform power allocation on the combined signal to obtain N combined sub-signals, each of the N combined sub-signals including a corresponding first sub-signal in the N first sub-signals and a corresponding second sub-signal in the N second sub-signals, and send the corresponding combined sub-signals in the N combined sub-signals to each RU in the N RUs through the transmission medium. Since the second signal and the first signal have different frequency bands, the second signal and the first signal can be combined and transmitted on one transmission medium, thereby saving the use of the transmission medium and reducing costs.

[0012] In some possible implementations, the transmission medium includes twisted pair cables, coaxial cables, and optical fibers, thereby enabling signal transmission.

[0013] The second aspect of the present application provides a signal processing method for a communication system, wherein the communication system includes an AP and N RUs, where N is a positive integer greater than or equal to 2. In the present application, a first RU receives a first sub-signal sent by the AP through a transmission medium, and the first RU is one of the N RUs. Then, the first RU performs signal processing on the first sub-signal to obtain a first radio frequency sub-signal, and then sends the first radio frequency sub-signal through a first antenna. Then, due to the coverage of the N RUs, the coverage range is larger, and there is only one AP. The user equipment does not need to switch within the coverage range of the N RUs, so the service will not be interrupted, and the power consumption is lower compared to multiple APs.

[0014] In some possible implementations, the first RU receives the combined sub-signal sent by the AP through a transmission medium. Then, the first RU splits the combined sub-signal to obtain a first sub-signal and a second sub-signal. Since the second signal and the first signal have different frequency bands, the second signal and the first signal can be combined and transmitted on one transmission medium, thereby saving the use of transmission medium and reducing costs.

[0015] In some possible implementations, the first RU performs frequency conversion on the first sub-signal and the second sub-signal, respectively, to obtain a first channel sub-signal corresponding to the first sub-signal and a second channel sub-signal corresponding to the second sub-signal, wherein the first channel sub-signal and the second channel sub-signal have the same frequency band. Next, the first RU performs signal processing on the second channel sub-signal to obtain a second RF sub-signal, and transmits the second RF sub-signal through the second antenna. Since the frequency band of the second sub-signal is smaller than that of the second channel sub-signal, and the frequency band of the first sub-signal is smaller than that of the first channel sub-signal, by reducing the frequency band of the signal to be transmitted, the consumption of the transmission medium can be reduced.

[0016] In some possible implementations, the transmission medium includes twisted pairs, coaxial cables, and optical fibers, thereby enabling signal transmission.

[0073] The embodiments of the present application provide a signal processing method and related devices for serving user equipment through an AP and N RUs to improve coverage and avoid service interruption.

[0074] The embodiments of the present application are described below with reference to the accompanying drawings.

[0075] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, and this is merely a way of distinguishing the objects of the same attributes when describing them in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0076] With the continuous evolution of wireless fidelity (WiFi) technology, the number of streams supported by the WiFi protocol continues to increase, the modulation order continues to rise, and the operating bandwidth remains unchanged. As a result, the maximum performance between access points (APs) and user devices often far exceeds actual user needs. However, WiFi performance can still be insufficient, leading to service lags and interruptions. This is primarily due to two reasons: 1. An insufficient number of APs / wireless routers, resulting in weak signal coverage in some areas; 2. Terminals switching between different APs / wireless routers (terminal roaming) can cause long service interruptions during the switching process.

[0077] To address this issue, there are three common Wi-Fi coverage solutions for larger areas (e.g., larger than 100 square meters): Solution 1: Access Controller (AC) / Cloud Controller + Fit APs; Solution 2: Fat APs / Wireless Routers; and Solution 3: Mesh Networking of Fat APs / Wireless Routers. Each solution is described in detail below.

[0078] Solution 1 (AC / cloud controller + Fit AP), as shown in Figure 1-1 or Figure 1-2, uses n Fit APs to provide coverage in an area, ensuring strong signal coverage at every location. These n Fit APs are connected to the AC / cloud controller via a wired network. User device access, roaming, and Fit AP configuration and management are all managed centrally by the AC / cloud controller. Solution 1 can achieve strong signal coverage at every location. However, each coverage point requires a Fit AP, each with its own baseband and forwarding plane, resulting in high cost and power consumption. Furthermore, while the AC / cloud controller can centrally manage user device behavior, switching between different APs (terminal roaming) can still take a long time, leading to service interruptions and a poor user experience.

[0079] Solution 2 (Fat AP / wireless router), as shown in Figure 1-3, uses n Fat APs / wireless routers to provide coverage within an area, ensuring strong signal coverage at every location. These n Fat APs / wireless routers connect to the same wired network, and each independently manages the access, configuration, and device management of its own user devices. While using only one Fat AP / wireless router in Solution 2 eliminates the issue of terminal roaming, a single Fat AP / wireless router has a limited coverage range. In larger areas or when coverage requires penetration through walls, weak signal coverage can often occur in some locations, resulting in poor service or even service interruption. Using multiple Fat APs / wireless routers is not only costly, but user devices cannot automatically roam between multiple Fat APs / wireless routers. User devices must manually connect to different Fat APs / wireless routers at different locations, impacting the user experience.

[0080] Solution 3 (Mesh networking of Fat APs / wireless routers), as shown in Figure 1-4, uses n Fat APs / wireless routers to provide coverage within an area, ensuring strong signal coverage at every location. Only a few of the n Fat APs / wireless routers are connected to the wired network (typically, only one). Each Fat AP / wireless router connects to one or more adjacent Fat APs / wireless routers via wireless signals, and then connects to the wired network through the Fat APs / wireless routers connected to the wired network. Solution 3 can achieve strong signal coverage at every location, but each coverage point requires a Fat AP / wireless router, and each Fat AP / wireless router requires its own baseband and forwarding plane, resulting in high cost and power consumption. Furthermore, user device roaming still exists, and switching between different APs can still take a long time, resulting in extended service interruption. Furthermore, Fat APs / wireless routers are connected wirelessly, and there may be poor wireless connectivity (for example, when there are two physical walls between two Fat APs / wireless routers), resulting in poor network performance for user devices within the coverage area of ​​the Fat AP / wireless router.

[0081] In summary, each node of the above three solutions is a complete WiFi signal (including digital signal processing, WiFi baseband, and RF signal processing), and the node cost is high and the power consumption is high.

[0082] The present application is applied to a communication system, which includes an AP and N radio units (RUs), where N is a positive integer greater than or equal to 2. In the present application, the AP can generate a first signal and perform power distribution on the first signal to obtain N first sub-signals. The AP then sends a corresponding first sub-signal in the N first sub-signals to each RU in the N RUs through a transmission medium. The N RUs and the N first sub-signals have a one-to-one correspondence. Due to the coverage of the N RUs, the coverage range is large, and there is only one AP. The user equipment does not need to switch within the coverage range of the N RUs, so the service will not be interrupted, and the power consumption is low.

[0083] The embodiment of the present application can be applied to a communication network as shown in FIG2-1 . Referring to FIG2-1 , the communication network 100 includes: a communication system 110 and a plurality of user equipments 120 .

[0084] In some possible implementations, the communication system 110 is a hardware device that connects two or more user devices and acts as a gateway between the user devices. The communication system 110 is a dedicated intelligent network device that can read the destination address in a message and determine how to transmit the message based on the destination address. The communication system 110 can understand different protocols, such as the Ethernet protocol used by a local area network and the Transmission Control Protocol / Internet Protocol (TCP / IP) protocol used by the Internet. In this way, the communication system 110 can analyze the destination addresses of messages transmitted from various types of networks, convert non-TCP / IP addresses into TCP / IP addresses, or vice versa, and then transmit each message to the destination address along the optimal transmission path based on a routing algorithm. Therefore, the communication system 110 can connect non-TCP / IP networks to the Internet.

[0085] In some possible implementations, the user terminal 120 may be a personal computer (PC), a modem, or a router with a dial-up function. The user terminal 120 may be referred to as a terminal, user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. The user terminal 120 may be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, 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 wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

[0086] In some possible implementations, the communication system 110 may be a single distributed WiFi coverage scenario or a multiple distributed WiFi coverage scenario, which are described below respectively.

[0087] Figure 2-2 shows an example of a single distributed WiFi coverage scenario. Communication system 110 includes an AP 111 and N radio units (RUs) 112 connected via a transmission medium. These N RUs 112 ensure strong signal coverage at every location. Based on the baseband coverage of a single AP 111, all terminals within the coverage area are connected to the same WiFi baseband, eliminating terminal roaming, handover time, and service interruption. A single distributed WiFi system (AP 111 and N RUs 112) is suitable for existing home coverage, small and micro businesses, or small branch offices.

[0088] As shown in Figure 2-3, it is a schematic diagram of multiple sets of distributed WiFi coverage scenarios. Among them, the communication system 110 includes multiple APs 111, and each AP 111 is connected to N RUs 112 through a transmission medium. Each AP 111 and the connected N RUs 112 are a single set of distributed WiFi coverage scenarios as shown in Figure 2-2, which will not be described in detail here. Multiple sets of distributed WiFi coverage scenarios are suitable for WiFi coverage of medium and large enterprises. Each set of distributed WiFi covers a certain area (n times the coverage area of ​​a single Fit AP / wireless router). Between different distributed WiFi coverage areas, a better roaming experience is achieved through protocol and software optimization (after using distributed WiFi, co-channel interference is reduced, the number of roaming times is reduced, and it is more conducive to software optimization of the overall roaming experience).

[0089] In some possible implementations, AP 111 may be a home router that can transmit WiFi signals, or a router that can transmit Bluetooth signals, which is not limited here.

[0090] The above describes the communication system provided by this application. Next, we will introduce the signal processing method performed based on this communication system. This signal processing method is applied to a communication system that includes an AP and N RUs, where N is a positive integer greater than or equal to 2, that is, a single set of distributed WiFi coverage scenarios.

[0091] The technical solution of the present application is described below through Example 1 and Example 2. In Example 1, after the AP performs frequency conversion on multiple channel signals, multiple signals are obtained. The AP combines the multiple signals to obtain a combined signal, and then performs power distribution on the combined signal to obtain N combined sub-signals, and then sends the N combined sub-signals to N RUs respectively through the transmission medium. In Example 2, the AP does not need to combine the multiple signals, but instead performs power distribution on each of the multiple signals to obtain N sub-signals of each signal, and then sends the N sub-signals of each of the multiple signals to N RUs respectively through the transmission medium.

[0092] Referring to FIG. 3-1 (steps 301 to 306) and FIG. 3-2 (steps 307 to 310), the signal processing method provided in the first embodiment of the present application mainly includes the following steps:

[0093] 301. The AP generates a baseband signal.

[0094] In some possible implementations, when an AP receives a data packet sent by a user device, it can generate a baseband signal based on the data packet. It should be noted that the original, unmodulated electrical signal sent by the transmitting user device is characterized by a low frequency and carries the information to be transmitted. This original electrical signal is called a baseband signal.

[0095] For example, the user equipment receives the application layer message "Hello", which is encapsulated layer by layer to obtain a data message, which is sent to the AP, and the AP converts the data message into a baseband signal.

[0096] 302. The AP generates a first channel signal, a second channel signal, a third channel signal, and a fourth channel signal based on the baseband signal. The first channel signal and the second channel signal have the same frequency band, and the third channel signal and the fourth channel signal have the same frequency band.

[0097] In some possible implementations, the AP may generate multiple channel signals having the same frequency band based on the baseband signal, for example, generate a first channel signal and a second channel signal, wherein the first channel signal and the second channel signal have the same frequency band.

[0098] In some possible implementations, the AP may generate multiple channel signals of different frequency bands based on the baseband signal, for example, a first channel signal and a third channel signal, where the first channel signal and the third channel signal have different frequency bands.

[0099] In some possible implementations, the AP can generate multiple channel signals with different frequency bands based on the baseband signal, for example, generating a first channel signal, a second channel signal, a third channel signal, and a fourth channel signal, wherein the frequency bands of the first channel signal and the second channel signal are the same, the frequency bands of the third channel signal and the fourth channel signal are the same, and the frequency bands of the first channel signal and the second channel signal are different from the frequency bands of the third channel signal and the fourth channel signal.

[0100] For example, the AP includes two basebands: 2.4 Ghz 2 transmit 2 receive (2T2R) and 5G 2T2R. The AP can process the baseband signal to generate a first channel signal, a second channel signal, a third channel signal, and a fourth channel signal, wherein the frequency band of the first channel signal and the second channel signal is 2.4 GHz, and the frequency band of the third channel signal and the fourth channel signal is 5.0 GHz.

[0101] 303. The AP performs frequency conversion on the first channel signal, the second channel signal, the third channel signal, and the fourth channel signal, respectively, to obtain a first signal corresponding to the first channel signal, a second signal corresponding to the second channel signal, a third signal corresponding to the third channel signal, and a fourth signal corresponding to the fourth channel signal, where the second signal and the first signal have different frequency bands, and the fourth signal and the third signal have different frequency bands.

[0102] Exemplarily, the first channel signal and the second channel signal are both signals in the 2.4 GHz frequency band. The AP frequency-converts the first communication signal into the first signal and the second communication signal into the second signal, such that the first signal and the second signal have different frequency bands. Exemplarily, the first signal may be in the 0.2 GHz frequency band, and the second signal may be in the 0.4 GHz frequency band.

[0103] Exemplarily, the third channel signal and the fourth channel signal are both signals in the 5.0 GHz frequency band. The AP frequency-converts the third communication signal into the third signal and the fourth communication signal into the fourth signal, such that the third signal and the fourth signal have different frequency bands. Exemplarily, the third signal may be in the 0.6 GHz frequency band, and the fourth signal may be in the 0.8 GHz frequency band.

[0104] In an embodiment of the present application, by reducing the frequency conversion of the first channel signal, the second channel signal, the third channel signal and the fourth channel signal by the AP, the frequency is reduced, and the loss of the transmission medium can be reduced when it is subsequently sent through the transmission medium.

[0105] 304. The AP combines the first signal, the second signal, the third signal, and the fourth signal to obtain a combined signal.

[0106] In an embodiment of the present application, the AP may combine the first signal, the second signal, the third signal, and the fourth signal, that is, superimpose the first signal, the second signal, the third signal, and the fourth signal in the time domain and the frequency domain to obtain a combined signal.

[0107] 305. The AP distributes power on the combined signal to obtain N combined sub-signals.

[0108] In the embodiment of the present application, after the AP combines the first signal, the second signal, the third signal, and the fourth signal to obtain a combined signal, the AP can perform power allocation on the combined signal to obtain N combined sub-signals. It should be noted that the frequency band and phase of the N combined sub-signals are the same as those of the combined signal.

[0109] For example, if N=3, the AP can perform power allocation on the combined signal to obtain three combined sub-signals, namely a first combined sub-signal, a second combined signal, and a third combined signal. The combined signal, the first combined sub-signal, the second combined signal, and the third combined signal all have the same frequency and phase.

[0110] In some possible implementations, the AP may distribute the power of the combined signal evenly, or may distribute the power proportionally as needed, which is not limited here. For example, the first combined sub-signal, the second combined sub-signal, and the third combined sub-signal each receive 1 / 3 of the energy of the combined signal. For another example, the first combined sub-signal receives 1 / 2 of the energy of the combined signal, and the second combined sub-signal and the third combined sub-signal each receive 1 / 4 of the energy of the combined signal, which is not limited here.

[0111] 306. The AP sends a corresponding combined sub-signal among the N combined sub-signals to each RU in the N RUs through a transmission medium.

[0112] In some possible implementations, after the AP performs power allocation on the combined signal and obtains N combined sub-signals, the N combined sub-signals can be sent to N RUs, respectively, so that each RU receives a corresponding combined sub-signal. For example, the communication system has three RUs, namely RU1, RU2, and RU3. The AP then performs power allocation on the combined signal and obtains three combined sub-signals, namely a first combined sub-signal, a second combined sub-signal, and a third combined sub-signal. The AP can then send the first combined sub-signal to RU1, the second combined sub-signal to RU2, and the third combined sub-signal to RU3.

[0113] In some possible implementations, the AP can send the N combined sub-signals to the N RUs via a transmission medium. It should be noted that a transmission medium is a physical path between different devices or components in a network. Common transmission media include twisted pair cables, coaxial cables, and optical fibers, and are not limited here.

[0114] In the embodiment of the present application, since the second signal and the first signal have different frequency bands, the second signal and the first signal can be combined and transmitted on one transmission medium, thereby saving the use of the transmission medium and reducing costs.

[0115] In the embodiment of the present application, when any one of the N RUs receives the combined sub-signal through the transmission medium, it may execute the steps executed by the first RU in steps 307 to 310 .

[0116] 307. The first RU splits the combined sub-signal to obtain a first sub-signal, a second sub-signal, a third sub-signal, and a fourth sub-signal. The first sub-signal and the second sub-signal have different frequency bands, and the third sub-signal and the fourth sub-signal have different frequency bands.

[0117] In some possible implementations, the first RU can receive a corresponding combined sub-signal among N combined sub-signals. For example, the communication system has three RUs, namely RU1, RU2 and RU3, wherein RU1 receives the first combined sub-signal, RU2 receives the second combined sub-signal, and RU3 receives the third combined sub-signal. Then, since the combined signal is obtained by combining the first signal, the second signal, the third signal and the fourth signal, the combined sub-signal and the combined signal have the same frequency, the first RU can perform signal branching on the received combined sub-signal to obtain the first sub-signal, the second sub-signal, the third sub-signal and the fourth sub-signal, wherein the first sub-signal has the same frequency band as the first signal, the second sub-signal has the same frequency band as the second signal, the third sub-signal has the same frequency band as the third signal, and the fourth sub-signal has the same frequency band as the fourth signal.

[0118] 308. The first RU performs frequency conversion on the first sub-signal, the second sub-signal, the third sub-signal, and the fourth sub-signal, respectively, to obtain a first channel sub-signal corresponding to the first sub-signal, a second channel sub-signal corresponding to the second sub-signal, a third channel sub-signal corresponding to the third sub-signal, and a fourth channel sub-signal corresponding to the fourth sub-signal.

[0119] In an embodiment of the present application, after the first RU performs signal splitting on the received combined sub-signal to obtain the first sub-signal, the second sub-signal, the third sub-signal, and the fourth sub-signal, the first RU can perform frequency conversion on the first sub-signal, the second sub-signal, the third sub-signal, and the fourth sub-signal to restore the first channel sub-signal, the second channel sub-signal, the third channel sub-signal, and the fourth channel sub-signal. The frequency bands of the first channel sub-signal and the second channel sub-signal are the same, and the frequency bands of the third channel sub-signal and the fourth channel sub-signal are the same. For example, the frequency bands of the first channel sub-signal and the second channel sub-signal are both 2.4 GHz, and the frequency bands of the third channel sub-signal and the fourth channel sub-signal are both 5.0 GHz.

[0120] 309 . The first RU performs signal processing on the first channel sub-signal, the second channel sub-signal, the third channel sub-signal, and the fourth channel sub-signal to obtain a first radio frequency sub-signal, a second radio frequency sub-signal, a third radio frequency sub-signal, and a fourth radio frequency sub-signal.

[0121] Exemplarily, the first RU processes the first channel sub-signal to obtain a first RF signal; the first RU processes the second channel sub-signal to obtain a second RF signal; the first RU processes the third channel sub-signal to obtain a third RF signal; and the first RU processes the fourth channel sub-signal to obtain a fourth RF signal. It should be noted that the first RF sub-signal, the second RF sub-signal, the third RF sub-signal, and the fourth RF sub-signal are signals that can be transmitted through the antenna.

[0122] 310. The first RU sends a first RF sub-signal, a second RF sub-signal, a third RF sub-signal, and a fourth RF sub-signal through the first antenna, the second antenna, the third antenna, and the fourth antenna, respectively.

[0123] Exemplarily, the first RU sends a first RF sub-signal through the first antenna, the first RU sends a second RF sub-signal through the second antenna, the first RU sends a third RF sub-signal through the third antenna, and the first RU sends a fourth RF sub-signal through the fourth antenna.

[0124] For example, the first RF sub-signal transmitted by the first antenna and the second RF sub-signal transmitted by the second antenna are both 2.4Ghz signals, the third RF sub-signal transmitted by the third antenna and the fourth RF sub-signal transmitted by the fourth antenna are both 5.0Ghz signals. Then, the AP can generate multiple signals and then achieve signal coverage through N RUs, so that the coverage range is larger, and there is only one AP. The user equipment does not need to switch within the coverage range of N RUs, so the service will not be interrupted and the power consumption is low.

[0125] In the embodiment of the present application, since the baseband is concentrated on the AP, N RUs can achieve good signal coverage in a larger area, and user devices do not roam when moving within the area, and no switching is required, thus avoiding service interruption. In addition, the distributed architecture of AP plus N RUs can reduce the baseband chip and the upper-layer data processing chip, achieving lower power consumption and lower cost. Since the N RUs do not have baseband chips and only involve RF signal processing, extremely low power consumption and extremely small size RUs can be achieved, which can simplify installation, make them more beautiful, and reduce the casing temperature. For example: make a RU that is the same size and ultra-thin as an 86 switch.

[0126] Referring to FIG. 4-1 (steps 401 to 405) and FIG. 4-2 (steps 406 to 408), the signal processing method provided in the second embodiment of the present application mainly includes the following steps:

[0127] 401. The AP generates a baseband signal.

[0128] Please refer to step 301, which will not be described in detail here.

[0129] 402. The AP generates a first channel signal, a second channel signal, a third channel signal, and a fourth channel signal based on the baseband signal. The first channel signal and the second channel signal have the same frequency band, and the third channel signal and the fourth channel signal have the same frequency band.

[0130] Please refer to step 302, which will not be described in detail here.

[0131] 403. The AP performs frequency conversion on the first channel signal, the second channel signal, the third channel signal, and the fourth channel signal, respectively, to obtain a first signal corresponding to the first channel signal, a second signal corresponding to the second channel signal, a third signal corresponding to the third channel signal, and a fourth signal corresponding to the fourth channel signal, wherein a frequency band of the first signal is smaller than a frequency band of the first channel signal, a frequency band of the second signal is smaller than a frequency band of the second channel signal, a frequency band of the third signal is smaller than a frequency band of the third channel signal, and a frequency band of the fourth signal is smaller than a frequency band of the fourth channel signal.

[0132] Exemplarily, the first channel signal and the second channel signal are both signals in the 2.4 GHz frequency band. The AP frequency-converts the first communication signal into the first signal and the second communication signal into the second signal, such that the first signal and the second signal have different frequency bands. Exemplarily, the first signal may be in the 0.2 GHz frequency band, and the second signal may be in the 0.4 GHz frequency band.

[0133] Exemplarily, the third channel signal and the fourth channel signal are both signals in the 5.0 GHz frequency band. The AP frequency-converts the third communication signal into the third signal and the fourth communication signal into the fourth signal, such that the third signal and the fourth signal have different frequency bands. Exemplarily, the third signal may be in the 0.6 GHz frequency band, and the fourth signal may be in the 0.8 GHz frequency band.

[0134] In an embodiment of the present application, the frequency of the first channel signal, the second channel signal, the third channel signal and the fourth channel signal are respectively converted by reducing the AP. Since the frequency band of the first signal is smaller than the frequency band of the first channel signal, the frequency band of the second signal is smaller than the frequency band of the second channel signal, the frequency band of the third signal is smaller than the frequency band of the third channel signal, and the frequency band of the fourth signal is smaller than the frequency band of the fourth channel signal, the frequency is reduced. When it is subsequently sent through the transmission medium, the loss of the transmission medium can be reduced.

[0135] 404. The AP performs power allocation on the first signal, the second signal, the third signal, and the fourth signal respectively to obtain N first sub-signals, N second sub-signals, N third sub-signals, and N fourth sub-signals.

[0136] In an embodiment of the present application, after the AP performs frequency conversion on the first channel signal, the second channel signal, the third channel signal, and the fourth channel signal, respectively, to obtain a first signal corresponding to the first channel signal, a second signal corresponding to the second channel signal, a third signal corresponding to the third channel signal, and a fourth signal corresponding to the fourth channel signal, the AP can perform power allocation on the first signal, the second signal, the third signal, and the fourth signal to obtain N first sub-signals, N second sub-signals, N third sub-signals, and N fourth sub-signals. It should be noted that the frequency band and phase of the N first sub-signals are the same as those of the first signal, the frequency band and phase of the N second sub-signals are the same as those of the second signal, the frequency band and phase of the N third sub-signals are the same as those of the third signal, and the frequency band and phase of the N fourth sub-signals are the same as those of the fourth signal.

[0137] For example, if N=3, the AP may perform power distribution on the first signal to obtain three first sub-signals, and the frequencies and phases of the first signal and the three first sub-signals are the same.

[0138] In some possible implementations, the AP may distribute signal power evenly or proportionally as needed, which is not limited here. For example, first sub-signal 1, first sub-signal 2, and first sub-signal 3 each receive 1 / 3 of the energy of the first signal. For another example, first sub-signal 1 receives 1 / 2 of the energy of the first signal, and first sub-signal 2 and first sub-signal 3 each receive 1 / 4 of the energy of the first signal, which is not limited here.

[0139] 405. The AP sends a first sub-signal corresponding to the N first sub-signals, a second sub-signal corresponding to the N second sub-signals, a third sub-signal corresponding to the N third sub-signals, and a fourth sub-signal corresponding to the N fourth sub-signals to each RU in the N RUs through a transmission medium.

[0140] In some possible implementations, after the AP allocates power to the first signal, the second signal, the third signal, and the fourth signal respectively, and obtains N first sub-signals, N second sub-signals, N third sub-signals, and N fourth sub-signals, the N first sub-signals, N second sub-signals, N third sub-signals, and N fourth sub-signals can be sent to N RUs respectively, so that each RU in the N RUs receives the first sub-signal, the second sub-signal, the third sub-signal, and the fourth sub-signal.

[0141] It should be noted that the transmission medium is the physical path between different devices or components in the network. Commonly used transmission media include twisted pair, coaxial cable, optical fiber, wireless transmission media, etc., which are not limited here.

[0142] In some possible implementations, the AP can send multiple sub-signals to the same RU via multiple transmission media, with a one-to-one correspondence between the transmission media and the sub-signals. By reducing the frequency bands of the first, second, third, and fourth channel signals, transmission medium consumption can be reduced.

[0143] 406. The first RU performs frequency conversion on the first sub-signal, the second sub-signal, the third sub-signal, and the fourth sub-signal, respectively, to obtain a first channel sub-signal corresponding to the first sub-signal, a second channel sub-signal corresponding to the second sub-signal, a third channel sub-signal corresponding to the third sub-signal, and a fourth channel sub-signal corresponding to the fourth sub-signal.

[0144] Please refer to step 308, which will not be described in detail here.

[0145] 407 . The first RU processes the first channel sub-signal, the second channel sub-signal, the third channel sub-signal, and the fourth channel sub-signal respectively to obtain a first radio frequency sub-signal, a second radio frequency sub-signal, a third radio frequency sub-signal, and a fourth radio frequency sub-signal.

[0146] Please refer to step 309, which will not be described here in detail.

[0147] 408. The first RU sends a first RF sub-signal, a second RF sub-signal, a third RF sub-signal, and a fourth RF sub-signal through the first antenna, the second antenna, the third antenna, and the fourth antenna, respectively.

[0148] Please refer to step 310, which will not be described in detail here.

[0149] The present application is applied to a communication system, which includes an AP and N RUs, where N is a positive integer greater than or equal to 2. In the present application, the AP can generate a first signal and perform power allocation on the first signal to obtain N first sub-signals. The AP then sends a corresponding first sub-signal in the N first sub-signals to each RU in the N RUs through a transmission medium. The N RUs and the N first sub-signals correspond one to one. Due to the coverage of the N RUs, the coverage range is large, and there is only one AP. The user equipment does not need to switch within the coverage range of the N RUs, so the service will not be interrupted, and the power consumption is low.
