Description

Technical Field

[0001] This application relates to the field of communication technology, and more particularly to a communication system and electronic device. Background Technology

[0002] In recent years, mobile satellite communication based on dual modems has been widely discussed and researched. Broadband and narrowband satellite communication is achieved by adding a set of modems and their corresponding radio frequency (RF) components (e.g., radio frequency integrated circuit (RFIC) and radio frequency front-end (RFFE)). However, adding components to achieve satellite communication increases the space occupied by the communication system, increasing the difficulty of hardware layout within a limited device size. Summary of the Invention

[0003] This application provides a communication system and electronic device to reduce the space occupied by the communication system and reduce the difficulty of hardware layout of the device.

[0004] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0005] In a first aspect, a communication system is provided. The communication system includes a first modem, a second modem, a first radio frequency (RF) chip, a second RF chip, a first front-end RF device, and a control circuit. The first modem is coupled to the first RF chip, and the second modem is coupled to the second RF chip. The first RF terminal of both the first RF chip and the second RF chip is coupled to the RF terminal of the first front-end RF device. The control circuit is coupled to both the first modem and the second modem, and is also coupled to the first front-end RF device.

[0006] In this embodiment, the first RF terminal of the first RF chip and the first RF terminal of the second RF chip are both coupled to the RF terminal of the first front-end RF device. This allows the first modem coupled to the first RF chip and the second modem coupled to the second RF chip to share the first front-end RF device. A control circuit coupled to the first modem, the second modem, and the first front-end RF device is added, allowing the first front-end RF device to be controlled by either the first modem or the second modem. This embodiment utilizes a control circuit to achieve dual-modem multiplexing of the front-end RF device, thereby reducing the number of front-end RF devices while still enabling satellite communication, thus reducing the space occupied by the communication system and helping to simplify the hardware layout of the equipment.

[0007] In some possible implementations, the control circuit is configured to: receive a first Mobile Industry Processor Interface (MIPI) instruction sent by a first modem, and receive a second MIPI instruction sent by a second modem. Based on priority instructions, it sends a first MIPI instruction to a first front-end radio frequency device; or, sends a second MIPI instruction to the first front-end radio frequency device. In the embodiments of this application, the control circuit can determine the priority of the first modem and the second modem based on priority instructions, and send the MIPI instruction sent by the higher-priority modem to the first front-end radio frequency device, so that the higher-priority modem controls the first front-end radio frequency device to transmit and receive radio frequency signals.

[0008] In some possible implementations, the communication system further includes a second front-end radio frequency (RF) device, wherein the second RF terminals of the first RF chip and the second RF chip are both coupled to the RF terminal of the second front-end RF device. The control circuit is also coupled to the second front-end RF device. This application embodiment couples the second RF terminals of the first RF chip and the second RF chip to the RF terminal of the first front-end RF device. This allows the first modem coupled to the first RF chip and the second modem coupled to the second RF chip to share the second front-end RF device, thereby further reducing the number of front-end RF devices. It should be understood that for multiple-input multiple-output (MIMO) communication systems, the corresponding RF terminals of the first and second RF chips can be coupled to the same front-end RF device, thereby greatly reducing the number of front-end RF devices and significantly reducing the space occupied by the communication system.

[0009] In some possible implementations, the first front-end RF device and the second front-end RF device serve as a front-end RF transmitter and a front-end RF receiver, respectively. That is, one of the first and second front-end RF devices is a front-end RF transmitter, and the other is a front-end RF receiver. The first and second front-end RF devices can be located in the main channel of the RF signal to process the transmitted and received RF signals.

[0010] In some possible implementations, both the first and second front-end RF devices are front-end RF receivers. One of the first and second front-end RF devices can be located in the main channel of the RF signal and cooperate with other front-end RF transmitters located in the main channel to process the transmitted and received RF signals. The other can be located in the diversity channel of the RF signal to process the received RF signal.

[0011] In some possible implementations, the control circuit is further configured to: send a first MIPI command to the first front-end RF device and the second front-end RF device based on the received priority command; or, send a second MIPI command to the first front-end RF device and the second front-end RF device. In embodiments of this application, if a modem has high communication quality requirements, it can occupy all the main channels and diversity channels.

[0012] In some possible implementations, the control circuit is further configured to: send a first MIPI command to a first front-end RF device and a second MIPI command to a second front-end RF device based on a received priority command; or, send a second MIPI command to the first front-end RF device and a first MIPI command to the second front-end RF device. In this application's implementation, when both the first and second front-end RF devices are front-end RF receivers, the modem with the higher priority controls the front-end RF receiver in the main channel (i.e., occupies the main channel); the modem with the lower priority controls the front-end RF receiver in the diversity channel (i.e., occupies the diversity channel).

[0013] In some possible implementations, the control circuit is further configured to: translate MIPI instructions, which include a first MIPI instruction and a second MIPI instruction; and send the translated MIPI instructions; wherein the unique slave identity (USID) in the translated MIPI instructions differs from the slave identity in the original MIPI instructions, or the address information (ADDS) in the translated MIPI instructions differs from the address information in the original MIPI instructions. Since the front-end RF transmitter and receiver devices located in the master channel may have devices with the same slave identity and address information, directly transmitting the original MIPI instructions could lead to instruction confusion. This application's implementation avoids instruction confusion by translating MIPI instructions to change the slave identity or address information in the MIPI instructions.

[0014] In a second aspect, an electronic device is provided. This electronic device includes a processor and a communication system according to any one of the first aspects described above, the processor being coupled to the communication system and configured to send priority instructions to the communication system.

[0015] In some possible implementations, the electronic device also includes an antenna coupled to the communication system.

[0016] In some possible implementations, the antenna includes a master antenna that is coupled to a front-end radio frequency transmitter and a front-end radio frequency receiver in the communication system, respectively.

[0017] In some possible implementations, the antenna also includes a diversity antenna that is coupled to a front-end radio frequency receiver in the communication system.

[0018] It should be understood that the technical effects of the second aspect can be referred to the technical effects of the first aspect and any of its embodiments, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0025] To make the purpose, technical solution, and advantages of this application clearer, the following is combined with Figures 1-5 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0026] The terms "first" and "second" used in the embodiments of this application are only used to distinguish features of the same type and should not be construed as indicating relative importance, quantity, order, etc.

Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0028] The terms "coupling" and "connection" used in the embodiments of this application should be interpreted broadly. For example, they can refer to a physical direct connection or an indirect connection achieved through electronic devices, such as a connection achieved through resistors, inductors, capacitors or other electronic devices.

[0029] This application provides an electronic device, which can be fixed or mobile. Additionally, this electronic device may also be referred to as user equipment (UE), terminal, terminal device, mobile station (MS), mobile terminal (MT), access terminal device, vehicle-mounted terminal device, industrial control terminal device, mobile station, remote station, remote terminal device, mobile device, wireless communication device, terminal agent, or terminal device, etc. For example, the electronic device may be a mobile phone, tablet, desktop computer, laptop computer, all-in-one computer, vehicle terminal, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, wearable device, terminal device in future mobile communication networks, or terminal device in future evolved public land mobile network (PLMN), etc.

[0030] like Figure 1As shown, the electronic device 100 includes a processor 110, a communication system 120, and an antenna 130. The processor 110 is coupled to the communication system 120 and is configured to send priority instructions to the communication system 120 based on the current application scenario of the electronic device 100. In some examples, the processor 110 may include one or more processing units. In some examples, the processing units may include field-programmable gate arrays (FPGAs), central processing units (CPUs), application processors (APs), network processors (NPs), digital signal processors (DSPs), microcontroller units (MCUs), programmable logic devices (PLDs), graphics processing units (GPUs), image signal processors (ISPs), controllers, video codecs, baseband processors, and neural-network processing units (NPUs), etc. In some examples, different processing units may be independent devices; for example, the processor 110 may be an application processor (AP). In some examples, processor 110 may also be a system-on-chip (SoC) that integrates multiple processing units.

[0031] The processor 110 may also include a memory for storing computer instructions and data. In some embodiments, the memory in the processor 110 is a cache. This memory can store computer instructions or data that the processor 110 has just used or that are used repeatedly. If the processor 110 needs to use the same computer instructions or data again, it can retrieve them directly from the memory. This avoids repeated accesses, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

[0032] Figure 2 A schematic diagram of the structure of a communication system 120 is shown. Figure 2As shown, the communication system 120 includes a first modem 210, a second modem 220, a first radio frequency (RF) chip 230, a second RF chip 240, and front-end RF devices 250. The first modem 210 is coupled to the first RF chip 230, which is also coupled to a set of front-end RF devices 250. The second modem 220 is coupled to the second RF chip 240, which is also coupled to another set of front-end RF devices 250. The front-end RF devices 250 are used to couple to the antenna 130. The first modem 210 can directly control the corresponding front-end RF device 250 to process the transmitted and received RF signals through the first RF chip 230. Similarly, the second modem 220 can directly control the corresponding front-end RF device 250 to process the transmitted and received RF signals through the second RF chip 240. Figure 2 The communication system 120 shown can achieve both broadband and narrowband satellite communication by adding a set of modems and their corresponding radio frequency devices. However, in Figure 2 In the communication system 120 shown, the independent dual modem scheme also greatly increases the space occupied by the communication system 120, and increases the difficulty of hardware layout of the device within the limited device size.

[0033] This application embodiment adds a control circuit 260 coupled to the first modem 210, the second modem 220, and the front-end radio frequency device 250. The control circuit 260 enables the front-end radio frequency device 250 to be controlled by the first modem 210 or by the second modem 220, thereby realizing the dual-modem multiplexing of the front-end radio frequency device 250. While realizing satellite communication, it reduces the number of front-end radio frequency devices 250, thereby reducing the space occupied by the communication system 120 and helping to reduce the difficulty of hardware layout of the equipment.

[0034] like Figure 3 As shown, the communication system 120 includes a first modem 210, a second modem 220, a first radio frequency chip 230, a second radio frequency chip 240, a control circuit 260, and multiple front-end radio frequency devices 250. The front-end radio frequency devices 250 may include any one or more combinations of power amplifiers (PAs), filters, low-noise amplifiers (LNAs), switches, duplexers, and tuners. In some examples, the front-end radio frequency devices 250 can filter, amplify, or otherwise process received electromagnetic waves (or electromagnetic waves to be transmitted).

[0035] A modem may include a modulator and a demodulator. The modulator modulates a low-frequency baseband signal to be transmitted into a mid-to-high frequency signal. The demodulator demodulates a received electromagnetic wave signal into a low-frequency baseband signal. For example, the demodulator transmits the demodulated low-frequency baseband signal to a baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is passed to an application processor. The application processor outputs sound signals through an audio device (not limited to a speaker, receiver, etc.) or displays images or videos on a screen.

[0036] The first modem 210 is coupled to the first RF chip 230, and the second modem 220 is coupled to the second RF chip 240. Both the first RF chip 230 and the second RF chip 240 include multiple RF terminals. Each RF terminal of the first RF chip 230 is coupled to a corresponding RF terminal of the second RF chip 240, and then coupled to a corresponding RF device 250. For example, the first RF terminals of the first RF chip 230 and the second RF chip 240 are both coupled to the RF terminals of the first front-end RF device 250, and the second RF terminals of the first RF chip 230 and the second RF chip 240 are both coupled to the RF terminals of the second front-end RF device 250. The first front-end RF device 250 can be either a front-end RF transmitter or a front-end RF receiver; similarly, the second front-end RF device 250 can be either a front-end RF transmitter or a front-end RF receiver. The control circuit 260 is coupled to the first modem 210, the second modem 220, and the multiple front-end RF devices 250.

[0037] In this embodiment, multiple radio frequency (RF) terminals of the first modem 210 are coupled one-to-one with the RF terminals of the second modem 220, sharing multiple front-end RF devices 250. A control circuit 260 is added so that the multiple front-end RF devices 250 can be controlled by the first modem 210 or by the second modem 220. This achieves dual-modem multiplexing of the front-end RF devices 250, reducing the number of front-end RF devices 250 while still enabling satellite communication. Especially in the multiple-input multiple-output (MIMO) communication system 120, this significantly reduces the space occupied by the communication system 120 and greatly simplifies the hardware layout of the equipment.

[0038] To facilitate understanding of the implementation methods of this application, Figure 3 The first RF chip 230 and the second RF chip 240 shown each include one RF transmitter and two RF receivers (correspondingly, the communication system 120 includes one front-end RF transmitter and two front-end RF receivers) as an example for illustration. Figure 3As shown, the first RF transmitter TX1 of the first RF chip 230 and the first RF transmitter TX1 of the second RF chip 240 are both coupled to the first front-end RF transmitter device 251. The first RF receiver RX1 of the first RF chip 230 and the first RF receiver RX1 of the second RF chip 240 are both coupled to the first front-end RF receiver device 252. The second RF receiver RX2 of the first RF chip 230 and the second RF receiver RX2 of the second RF chip 240 are both coupled to the second front-end RF receiver device 253.

[0039] The front-end RF device 250 is used for coupling with the antenna 130. In some embodiments, the RF chip and the front-end RF device 250 can be integrated with the antenna 130 as an active antenna unit (AAU), and the modem is connected to the active antenna unit. In other embodiments, the front-end RF device 250 and the antenna 130 are independent devices, and the front-end RF device 250 is connected to the antenna 130 via a feed line.

[0040] Antenna 130 may include a main antenna 131 and a diversity antenna 132. In some examples, a first front-end RF transmitter 251 and a first front-end RF receiver 252 are coupled to the same main antenna 131; that is, the first front-end RF transmitter 251 and the first front-end RF receiver 252 are disposed in the main channel of the RF signal to process the transmitted and received RF signals. A second front-end RF receiver 253 is coupled to the diversity antenna 132; that is, the second front-end RF receiver 253 is disposed in the diversity channel of the RF signal to process the received RF signal.

[0041] Please continue to refer to Figure 3 The control circuit 260 is coupled to the first modem 210 and the second modem 220, respectively. The control circuit 260 is also coupled to the first front-end RF transmitter 251, the first front-end RF receiver 252, and the second front-end RF receiver 253, respectively. In some embodiments, the control circuit 260 is configured to: receive a first MIPI command sent by the first modem 210, receive a second MIPI command sent by the second modem 220, and receive a priority command sent by the processor 110.

[0042] In some examples, the priority instruction indicates that the priority of the first modem 210 is higher than that of the second modem 220. Then, the control circuit 260 sends a first MIPI instruction to the first front-end RF transmitter 251 and the first front-end RF receiver 252 located in the master channel based on the priority instruction sent by the processor 110.

[0043] In other examples, if a priority instruction indicates that the second modem 220 has a higher priority than the first modem 210, then the control circuit 260 sends a second MIPI instruction to the first front-end RF transmitter 251 and the first front-end RF receiver 252 located in the master channel based on the priority instruction sent by the processor 110. That is, the modem with the relatively higher priority controls the front-end RF receiver in the master channel (i.e., occupies the master channel) and has higher control over the front-end RF device 250.

[0044] Because the front-end RF transmitter and receiver devices in the main channel may contain devices with the same slave identifier and address information, direct transmission of the original MIPI command can lead to command confusion. Therefore, in some embodiments, the control circuit 260 also stores an eject table for translating MIPI commands, and the control circuit 260 is further configured to: translate MIPI commands, including a first MIPI command and a second MIPI command; and send the translated MIPI command. As shown in Table 1 below, in some embodiments, the address information in the translated MIPI command is different from the address information in the original MIPI command. In other embodiments, the slave identifier in the translated MIPI command is different from the slave identifier in the original MIPI command (not shown). This changes the slave identifier or address information in the MIPI command to avoid command confusion.

[0045] Table 1

[0046]

[0047] As mentioned above, higher-priority modems have greater control over the front-end RF device 250. Figure 4 and Figure 5 As shown, in some examples, when the first modem 210 and the second modem 220 are operating concurrently, if the higher-priority first modem 210 needs to perform a service, even if the lower-priority second modem 220 is occupying the main channel and diversity channel (i.e., the front-end RF devices in the main channel and the front-end RF devices in the diversity channel are receiving the second MIPI command), the control circuit 260 will send the first MIPI command to the front-end RF device located in the main channel because the first modem 210 has a higher priority than the second modem 220. This causes the first modem 210 to preempt the main channel. Furthermore, the control circuit 260 will also notify the processor 110 of the main channel preemption by triggering an interrupt.

[0048] In some implementations, a higher-priority modem may occupy only the main channel, while a lower-priority modem may control the front-end RF receiver in the diversity channel (i.e., occupy the diversity channel). In some examples, a priority instruction indicates that the first modem 210 has a higher priority than the second modem 220. Based on the priority instruction sent by the processor 110, the control circuit 260 sends a first MIPI instruction to the first front-end RF transmitter 251 and the first front-end RF receiver 252 located in the main channel, and a second MIPI instruction to the second front-end RF receiver 253 located in the diversity channel (e.g., ...). Figure 4 As shown; that is, the front-end RF device in the main channel receives the first MIPI instruction, and the front-end RF device in the diversity channel receives the second MIPI instruction. In other examples, the priority instruction indicates that the priority of the second modem 220 is higher than the priority of the first modem 210. In this case, the control circuit 260 sends the second MIPI instruction to the first front-end RF transmitter 251 and the first front-end RF receiver 252 located in the main channel, and sends the first MIPI instruction to the second front-end RF receiver 253 located in the diversity channel, based on the priority instruction sent by the processor 110.

[0049] In other implementations, if a higher-priority modem has higher communication quality requirements, it can occupy all the main and diversity channels. In some examples, a priority instruction indicates that the first modem 210 has a higher priority than the second modem 220. Based on the priority instruction sent by the processor 110, the control circuit 260 sends a first MIPI instruction to the first front-end RF transmitter 251 and the first front-end RF receiver 252 located in the main channel, and sends a first MIPI instruction (e.g., to the second front-end RF receiver 253 located in the diversity channel) to the second front-end RF receiver 253 located in the diversity channel. Figure 5 As shown; that is, the front-end RF device in the main channel receives the first MIPI instruction, and the front-end RF device in the diversity channel receives the first MIPI instruction. In other examples, a priority instruction indicates that the priority of the second modem 220 is higher than that of the first modem 210. In this case, the control circuit 260 sends a second MIPI instruction to the first front-end RF transmitter 251 and the first front-end RF receiver 252 located in the main channel, and sends a second MIPI instruction to the second front-end RF receiver 253 located in the diversity channel, based on the priority instruction sent by the processor 110.

[0050] In this embodiment, the first RF terminal of the first RF chip 230 and the first RF terminal of the second RF chip 240 are both coupled to the RF terminal of the first front-end RF device 250. This allows the first modem 210 coupled to the first RF chip 230 and the second modem 220 coupled to the second RF chip 240 to share the first front-end RF device 250. A control circuit 260 is added, coupled to the first modem 210, the second modem 220, and the first front-end RF device 250, so that the first front-end RF device 250 can be controlled by the first modem 210 or by the second modem 220. This embodiment utilizes the control circuit 260 to achieve dual-modem multiplexing of the front-end RF device 250, thereby reducing the number of front-end RF devices 250 while still achieving satellite communication, thus reducing the space occupied by the communication system 120 and helping to simplify the hardware layout of the equipment.
