Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication system and electronic equipment. Background Art

[0002] In recent years, mobile satellite communication based on dual modems has been widely discussed and studied. By adding a set of modems and their corresponding RF devices (for example, RF chips (RFIC) and RF front-end devices (RFFE)), wide-band and narrow-band satellite communication can be achieved. However, the space occupied by the communication system is increased by adding devices, which increases the difficulty of hardware layout of the device under the limited device size. Summary of the invention

[0003] The embodiments of the present application provide a communication system and an electronic device, which are used 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 the present 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 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 end of the first RF chip and the first RF end of the second RF chip are both coupled to the RF end of the first front-end RF device. The control circuit is coupled to the first modem and the second modem respectively, and the control circuit is also coupled to the first front-end RF device.

[0006] In the implementation manner of the present application, the first RF end of the first RF chip and the first RF end of the second RF chip are both coupled to the RF end of the first front-end RF device. As a result, the first modem coupled to the first RF chip and the second modem coupled to the second RF chip 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 additionally provided, so that the first front-end RF device can be controlled by the first modem; or, controlled by the second modem. The implementation manner of the present application utilizes a control circuit to realize dual-modem multiplexing of front-end RF devices, thereby reducing the number of front-end RF devices on the basis of realizing satellite communications, thereby reducing the space occupied by the communication system, and helping to reduce the difficulty of 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 the first modem, and receive a second MIPI instruction sent by the second modem. Based on the priority instruction, send the first MIPI instruction to the first front-end RF device; or, send the second MIPI instruction to the first front-end RF device. The control circuit in the implementation method of the present application can determine the priority of the first modem and the second modem based on the priority instruction, and send the MIPI instruction sent by the high-priority modem to the first front-end RF device, so that the high-priority modem controls the first front-end RF device to receive and transmit RF signals.

[0008] In some possible implementations, the communication system further includes a second front-end RF device, and the second RF end of the first RF chip and the second RF end of the second RF chip are both coupled to the RF end of the second front-end RF device. The control circuit is also coupled to the second front-end RF device. The implementation of the present application couples the second RF end of the first RF chip and the second RF end of the second RF chip to the RF end of the first front-end RF device. As a result, the first modem coupled to the first RF chip and the second modem coupled to the second RF chip share the second front-end RF device, thereby further reducing the number of front-end RF devices. It should be understood that for a multiple-input multiple-output (MIMO) communication system, the RF ends corresponding to the first RF chip and the second RF chip 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 are each other a front-end RF transmitting device and a front-end RF receiving device. That is, one of the first front-end RF device and the second front-end RF device is a front-end RF transmitting device, and the other is a front-end RF receiving device. The first front-end RF device and the second front-end RF device can be arranged in the main set channel of the RF signal to process the transmitted and received RF signals.

[0010] In some possible implementations, the first front-end RF device and the second front-end RF device are both front-end RF receiving devices. One of the first front-end RF device and the second front-end RF device can be set in the main set channel of the RF signal, and cooperate with the other front-end RF transmitting device set in the main set channel to process the received and transmitted RF signals. The other can be set 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 instruction to the first front-end RF device and the second front-end RF device based on the received priority instruction; or send a second MIPI instruction to the first front-end RF device and the second front-end RF device. In the implementation of the present application, if a modem has a higher requirement for communication quality, it can occupy all main set channels and diversity channels.

[0012] In some possible implementations, the control circuit is further configured to: send a first MIPI instruction to the first front-end RF device and send a second MIPI instruction to the second front-end RF device based on the received priority instruction; or send a second MIPI instruction to the first front-end RF device and send a first MIPI instruction to the second front-end RF device. In the implementation of the present application, when the first front-end RF device and the second front-end RF device are both front-end RF receiving devices, the modem with a relatively higher priority controls the front-end RF receiving device in the main set channel (i.e., occupies the main set channel); the modem with a relatively lower priority controls the front-end RF receiving device 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, the MIPI instructions including a first MIPI instruction and a second MIPI instruction. Send the translated MIPI instruction; wherein the unique sl ave identity (USID) in the translated MIPI instruction is different from the slave identity in the MIPI instruction, or the address information (ADDS) in the translated MIPI instruction is different from the address information in the MIPI instruction. Since the front-end RF transmitting device and the front-end RF receiving device set in the main set channel may have devices with the same slave identity and address information, direct transmission of the original MIPI instruction may result in instruction confusion. The implementation method of the present application translates the MIPI instruction to change the slave identity or address information in the MIPI instruction to avoid instruction confusion.

[0014] In a second aspect, an electronic device is provided, comprising a processor and the communication system according to any one of the first aspects, wherein the processor is coupled to the communication system and is configured to send a priority instruction to the communication system.

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

[0016] In some possible implementations, the antenna includes a main antenna, and the main antenna is respectively coupled to a front-end radio frequency transmitting device and a front-end radio frequency receiving device in the communication system.

[0017] In some possible implementations, the antenna further includes a diversity antenna, and the diversity antenna is coupled to a front-end radio frequency receiving device in the communication system.

[0018] It should be understood that the technical effects of the second aspect can refer to the technical effects of the first aspect and any of its embodiments, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[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 the processor 110 is configured to send a priority instruction 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, and in some examples, the processing unit may include a field programmable gate array (FPGA), a central processing unit (CPU), an application processor (AP), a network processor (NP), a digital signal processor (DSP), a micro control unit (MCU), a programmable logic device (PLD), a graphics processor (GPU), an image signal processor (ISP), a controller, a video codec, a baseband processor, and a neural network processing unit (NPU).

In some examples, processor 110 may also be a system on chip (SoC) integrating multiple processing units.

[0031] The processor 110 may also be provided with a memory for storing computer instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may store computer instructions or data that the processor 110 has just used or is cyclically using. If the processor 110 needs to use the computer instructions or data again, it may be directly called from the memory. This avoids repeated access, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

[0032] Figure 2 FIG. 1 shows a schematic diagram of the structure of a communication system 120. Figure 2As shown, the communication system 120 includes a first modem 210, a second modem 220, a first RF chip 230, a second RF chip 240, and a front-end RF device 250. The first modem 210 is coupled to the first RF chip 230, the first RF chip 230 is coupled to a group of front-end RF devices 250, the second modem 220 is coupled to the second RF chip 240, the second RF chip 240 is coupled to another group of front-end RF devices 250, and the front-end RF device 250 is used to couple the antenna 130. The first modem 210 can directly control the corresponding front-end RF device 250 to process the received and transmitted 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 received and transmitted RF signals through the second RF chip 240. Figure 1 The communication system 120 shown can realize wideband and narrowband satellite communication by adding a set of modems and their corresponding radio frequency devices. Figure 1 In the communication system 120 shown, the independent dual modem solution also greatly increases the space occupied by the communication system 120, and increases the difficulty of hardware layout of the device under the limited device size.

[0033] The embodiment of the present application adds a control circuit 260 coupled to the first modem 210, the second modem 220 and the front-end RF device 250, and utilizes the control circuit 260 to enable the front-end RF device 250 to be controlled by the first modem 210; or, to be controlled by the second modem 220, thereby realizing dual-modem multiplexing of the front-end RF device 250, while realizing satellite communication, reducing the number of front-end RF 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 RF chip 230, a second RF chip 240, a control circuit 260, and a plurality of front-end RF devices 250. The front-end RF device 250 may include any one or a combination of multiple items of a power amplifier (PA), a filter, a low noise amplifier (LNA), a switch, a duplexer, and a tuner. In some examples, the front-end RF device 250 may filter, amplify, and perform other processing on the received electromagnetic waves (or, the electromagnetic waves to be transmitted).

[0035] The modem may include a modulator and a demodulator. The modulator is used to modulate the low-frequency baseband signal to be sent into a medium-high frequency signal. The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. Exemplarily, the demodulator transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After being processed by the baseband processor, the low-frequency baseband signal is passed to the application processor. The application processor outputs a sound signal through an audio device (not limited to a speaker, a receiver, etc.), or displays an image or video through a display 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. The first RF chip 230 and the second RF chip 240 each include a plurality of RF terminals. After the plurality of RF terminals of the first RF chip 230 and the plurality of RF terminals of the second RF chip 240 are coupled one-to-one, they are coupled one-to-one with a plurality of front-end RF devices 250. Exemplarily, 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, and the second RF terminal of the first RF chip 230 and the second RF terminal of the second RF chip 240 are both coupled to the RF terminal of the second front-end RF device 250. Among them, the first front-end RF device 250 can be a front-end RF transmitting device or a front-end RF receiving device; similarly, the second front-end RF device 250 can be a front-end RF transmitting device or a front-end RF receiving device. The control circuit 260 is coupled to the first modem 210, the second modem 220 and the plurality of front-end RF devices 250, respectively.

[0037] In the embodiment of the present application, the multiple RF terminals of the first modem 210 are coupled to the RF terminals of the second modem 220 in a one-to-one correspondence, and multiple front-end RF devices 250 are shared. 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. Thus, the dual modem multiplexing of the front-end RF devices 250 is achieved, and the number of front-end RF devices 250 is reduced on the basis of achieving satellite communication. In particular, the multi-input multi-output communication system 120 can significantly reduce the space occupied by the communication system 120, greatly reducing the difficulty of hardware layout of the device.

[0038] In order to facilitate understanding of the embodiments of the present application, Figure 3 The first RF chip 230 and the second RF chip 240 shown include one RF transmitting end and two RF receiving ends respectively (correspondingly, the communication system 120 includes one front-end RF transmitting device and two front-end RF receiving devices) as an example for explanation. Figure 3As shown, the first RF transmitting terminal TX1 of the first RF chip 230 and the first RF transmitting terminal TX1 of the second RF chip 240 are both coupled to the first front-end RF transmitting device 251, the first RF receiving terminal RX1 of the first RF chip 230 and the first RF receiving terminal RX1 of the second RF chip 240 are both coupled to the first front-end RF receiving device 252, and the second RF receiving terminal RX2 of the first RF chip 230 and the second RF receiving terminal RX2 of the second RF chip 240 are both coupled to the second front-end RF receiving device 253.

[0039] The front-end RF device 250 is used to couple with the antenna 130. In some embodiments, the RF chip and the front-end RF device 250 can be integrated with the antenna 130 to form 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 feeder.

[0040] The antenna 130 may include a main antenna 131 and a diversity antenna 132. In some examples, the first front-end RF transmitting device 251 and the first front-end RF receiving device 252 are coupled to the same main antenna 131; that is, the first front-end RF transmitting device 251 and the first front-end RF receiving device 252 are arranged in the main channel of the RF signal to process the received and transmitted RF signals. The second front-end RF receiving device 253 is coupled to the diversity antenna 132; that is, the second front-end RF receiving device 253 is arranged 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, and is also coupled to the first front-end RF transmitting device 251, the first front-end RF receiving device 252, and the second front-end RF receiving device 253 respectively. In some embodiments, the control circuit 260 is configured to: receive a first MIPI instruction sent by the first modem 210, receive a second MIPI instruction sent by the second modem 220, and receive a priority instruction sent by the processor 110.

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

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

[0044] Since there may be devices with the same slave identification and address information in the front-end RF transmitting device and the front-end RF receiving device set in the main set channel, direct transmission of the original M IPI instruction may cause instruction confusion. Therefore, in some embodiments, the control circuit 260 also stores an elicitation table for translating the M IPI instruction, and the control circuit 260 is also configured to: translate the M IPI instruction, and the M IPI instruction includes a first M IPI instruction and a second M IPI instruction. Send the translated MIPI instruction. As shown in Table 1 below, in some embodiments, the address information in the translated M IPI instruction is different from the address information in the M IPI instruction. In other embodiments, the slave identification in the translated M IPI instruction is different from the slave identification in the M IPI instruction (not shown). Thereby changing the slave identification or address information in the M IPI instruction to avoid instruction confusion.

[0045] Table 1

[0046]

[0047] As described above, a modem with a relatively higher priority has a higher control authority 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 work concurrently, if the first modem 210 with a higher priority needs to execute a service, even if the second modem 220 with a lower priority is occupying the main set channel and the diversity channel to work (i.e., the front-end RF device in the main set channel and the front-end RF device in the diversity channel receive the second MIPI instruction), since the priority of the first modem 210 is higher than that of the second modem 220, the control circuit 260 will send the first MIPI instruction to the front-end RF device in the main set channel, so that the first modem 210 preempts the main set channel. In addition, the control circuit 260 will also notify the processor 110 of the preemption of the main set channel by triggering an interrupt.

[0048] In some implementations, a relatively high-priority modem may occupy only the main set channel, and a relatively low-priority modem may also control the front-end RF receiving device in the diversity channel (i.e., occupy the diversity channel). In some examples, the priority instruction indicates that the priority of the first modem 210 is higher than the priority of the second modem 220, then the control circuit 260 sends a first MIPI instruction to the first front-end RF transmitting device 251 and the first front-end RF receiving device 252 in the main set channel based on the priority instruction sent by the processor 110, and sends a second MIPI instruction to the second front-end RF receiving device 253 in the diversity channel (e.g., Figure 4 As shown; that is, the front-end RF device in the main set 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, then the control circuit 260 sends the second MIPI instruction to the first front-end RF transmitting device 251 and the first front-end RF receiving device 252 in the main set channel based on the priority instruction sent by the processor 110, and sends the first MIPI instruction to the second front-end RF receiving device 253 in the diversity channel.

[0049] In other embodiments, if a relatively high-priority modem has a higher requirement for communication quality, it may occupy all the main set channels and the diversity channels. In some examples, the priority instruction indicates that the priority of the first modem 210 is higher than the priority of the second modem 220, then the control circuit 260 sends a first MIPI instruction to the first front-end RF transmitting device 251 and the first front-end RF receiving device 252 in the main set channel based on the priority instruction sent by the processor 110, and sends a first MIPI instruction to the second front-end RF receiving device 253 in the diversity channel (such as Figure 5 As shown; that is, the front-end RF device in the main set channel receives the first MIPI instruction, and the front-end RF device in the diversity channel receives the first 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, then the control circuit 260 sends a second MIPI instruction to the first front-end RF transmitting device 251 and the first front-end RF receiving device 252 in the main set channel based on the priority instruction sent by the processor 110, and sends a second MIPI instruction to the second front-end RF receiving device 253 in the diversity channel.

[0050] In the embodiment of the present application, the first RF end of the first RF chip 230 and the first RF end of the second RF chip 240 are both coupled to the RF end of the first front-end RF device 250. As a result, the first modem 210 coupled to the first RF chip 230 and the second modem 220 coupled to the second RF chip 240 share the first front-end RF device 250. A control circuit 260 coupled to the first modem 210, the second modem 220 and the first front-end RF device 250 is additionally provided, so that the first front-end RF device 250 can be controlled by the first modem 210; or, by the second modem 220. The embodiment of the present application utilizes the control circuit 260 to realize dual-modem multiplexing of the front-end RF device 250, thereby reducing the number of front-end RF devices 250 on the basis of realizing satellite communication, thereby reducing the space occupied by the communication system 120, and helping to reduce the difficulty of hardware layout of the device.
