Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.
[0047] Figure 1 illustrates a schematic diagram of a communication system. This system includes network equipment and terminal equipment. Network equipment is a device deployed in a radio access network to provide wireless communication functions for terminal equipment. Network equipment can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different radio access technologies, the name of the network equipment may differ, such as a base transceiver station (BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) network, a node B (NB) in Wideband Code Division Multiple Access (WCDMA), and an evolved Node B (eNB) in Long Term Evolution (LTE). Network equipment can also be a radio controller in a cloud radio access network (CRAN) scenario. Network equipment can also be base station equipment in a fifth-generation (5G) network or next-generation wireless communication network, or network equipment in a future public land mobile network (PLMN) network. Network devices can also be wearable devices or in-vehicle devices. Network devices can also be transmission and reception points (TRPs).
[0048] Terminal devices can be wireless communication devices, Internet of Things (IoT) devices, etc. They can include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem. Terminal devices can be mobile stations (MS), subscriber units, cellular phones, smartphones, wireless data cards, personal digital assistant (PDA) computers, tablet computers, wireless modems, handsets, laptop computers, machine-type communication (MTC) terminals, etc.
[0049] This communication system can be applied to Long Term Evolution (LTE) systems, Universal Mobile Telecommunications System (UMTS) systems, Code Division Multiple Access (CDMA) systems, Wireless Local Area Network (WLAN) systems, or the fifth generation (5G) or next-generation wireless communication systems.
[0050] The 3rd Generation Partnership Project (3GPP) has been researching energy-saving technologies for 5G terminal devices. While existing energy-saving technologies for terminal devices can significantly reduce power consumption, they still fall short of the power requirements of IoT terminals. For example, industrial sensor terminals cannot achieve a battery life of more than one year, and wearable terminals cannot achieve a battery life of more than two weeks.
[0051] Due to size limitations, terminal devices typically have small battery capacities and limited battery life. For example, 4G smartwatches have a standby time of approximately 2-6 days, while 5G smartwatches have a battery life of approximately 1-3 days. Therefore, reducing power consumption is crucial. In practical applications, a significant portion of the energy consumed by terminal devices is spent on idle listening when there is no signal. Low-power solutions in related technologies focus on optimizing the sleep strategies of terminal devices. When a terminal device is not sending or receiving messages, continuous channel listening will generate high power consumption. Therefore, a sleep schedule can be introduced, allowing the terminal device to enter deep sleep when there is no data transmission or reception, thereby reducing the energy consumption of continuous idle listening. However, when a terminal device is in deep sleep, it cannot communicate with other devices. Signal transmission between them can only occur after the terminal device wakes up, which may lead to some latency.
[0052] To avoid high latency caused by sleep mechanisms, terminal devices typically follow a certain sleep strategy, waking up periodically to check for data that needs to be received. However, this reduces the sleep efficiency of the terminal device because waking up without any data to send or receive consumes more energy than prolonged sleep. To reduce receiver power consumption, a longer sleep cycle can be used, allowing the terminal device to periodically activate for communication. During non-communication phases, the terminal device can enter sleep mode to reduce power consumption, but this introduces significant communication latency. If the terminal can be woken up on demand, both low power consumption and latency requirements can be simultaneously achieved.
[0053] Besides optimizing sleep strategies, another technical approach to reducing device power consumption is to use a low-power wake-up receiver (LP-WUR), or simply a wake-up receiver (WUR). This means that in addition to the traditional main modem, the communication device also includes a low-power wake-up modem. When the main modem enters sleep mode, the low-power wake-up modem wakes up and begins operation. The wake-up modem can perform on-demand wake-up functionality, that is, wake up the main modem when there is a communication need. Adding this auxiliary wake-up module to existing terminal receivers allows the main modem to remain off or in sleep mode when there is no communication need, while only the wake-up modem is activated to listen for the low-power wake-up signal (LP-WUR) and wake up the main modem in a timely manner. This can significantly save power consumption and improve energy efficiency.
[0054] To achieve low power consumption, wake-up modems (WURs) employ relatively simple circuit designs and wake-up signal frame structures. For example, a WUR circuit might only include energy detection and radio frequency (RF) components, typically using simple binary amplitude shift keying (OOK) or frequency shift keying (FSK) modulation. Low-power WURs can be continuously or intermittently powered on, receiving low-power wake-up signals when active. Due to their simple hardware, low-power wake-up receivers can reduce power consumption to the microwatt level, significantly improving battery life and endurance of terminal devices. They are widely applicable to wearable devices, Internet of Things (IoT) devices, and smartphones, and have garnered significant industry attention.
[0055] Figure 2 illustrates a schematic diagram of a low-power wake-up mechanism in related technologies. Introducing a low-power wake-up modem (LPWM) to process wake-up signals in the terminal device can reduce power consumption while maintaining low latency. For ease of description, the terminal device is divided into a main modem and a wake-up modem. When there is no service demand, the terminal device can activate a low-power mode. In low-power mode, the main modem is turned off or configured into sleep mode, and only the wake-up modem is turned on. The RF switch is switched to the wake-up RF channel, and the wake-up modem receives and processes the wake-up signal. When the network needs to communicate with the terminal, it can send a low-power wake-up signal. After successfully detecting the wake-up signal, the terminal-side wake-up modem triggers the main modem to turn on, the RF switch is switched to the main RF channel, and the main modem receives the main communication signal to complete the service processing.
[0056] In the related technology shown in Figure 2, the RF channel of the wake-up signal and the RF channel of the main communication signal have their own independent RF devices, and these two RF channels are switched using RF switches. The RF channels cannot be completely reused, resulting in an increase in the area and cost of the low-power wake-up receiver.
[0057] To address the aforementioned issues, this application provides a communication device comprising a main modem and a wake-up modem, wherein the main modem and the wake-up modem can reuse radio frequency channels, thereby reducing the area and cost of the communication device and saving control overhead.
[0058] Referring to Figure 3, the communication device provided in this application embodiment includes an antenna, a radio frequency front-end, a wake-up modem and a main modem and multiple radio frequency channels. The radio frequency front-end is disposed between the antenna and the radio frequency channels. The multiple radio frequency channels of the communication device include a first radio frequency channel, which is used to downconvert the received first radio frequency signal to obtain a first signal and transmit the first signal to the wake-up modem.
[0059] The wake-up modem is used to perform the first analysis processing on the first signal to determine whether the first signal is a wake-up signal. In order to reduce power consumption, the wake-up signal usually adopts a simple binary amplitude shift keying (OOK) modulation method or frequency shift keying (FSK) modulation method. Therefore, the wake-up modem only needs to complete the corresponding first analysis processing, that is, demodulate the first signal and determine the signal type of the first signal based on the amplitude, phase and other information of the first signal. The wake-up modem wakes up the main modem when the first signal is a wake-up signal.
[0060] When the main modem is woken up, the first radio frequency channel is also used to downconvert the received second radio frequency signal to obtain a second signal and transmit the second signal to the main modem. The second signal is a communication service signal, which is a signal carrying communication data that is different from the wake-up signal. The communication service signal carries a large amount of data. Compared with the modulation method such as OOK used by the wake-up signal, the communication service signal needs to use a more advanced and complex modulation method, such as quadrature phase shift keying (QPSK) modulation and quadrature amplitude modulation (QAM). The main modem is used to perform a second parsing process on the second signal, such as demodulating the second signal according to the corresponding demodulation method and parsing the set communication protocol.
[0061] The communication device also includes at least one second radio frequency channel, which is used to downconvert the third radio frequency signal to obtain a third signal and transmit the third signal to the main modem. The main modem is used to perform a second parsing process on the third signal, which is a communication service signal.
[0062] In one possible implementation, the communication device provided in this application embodiment is a communication device that uses carrier aggregation (CA) technology, or it may be a communication device that uses multiple-in multiple-out (MIMO). The carrier aggregation method includes at least one of continuous carrier aggregation within a frequency band, discontinuous carrier aggregation within a frequency band, and discontinuous carrier aggregation across frequency bands. In this case, the main modem is also used to perform a second parsing process on at least two of the second signal and multiple third signals.
[0063] In the communication device provided in this application embodiment, the wake-up modem and the main modem can reuse the radio frequency channel. For example, in a low-power state, the first radio frequency channel can be used to transmit a first signal to the wake-up modem; after the wake-up modem wakes up the main modem, the first radio frequency channel can also be used to transmit a second signal to the main modem. The first signal can be a wake-up signal, and the second signal can be a communication service signal. Reusing the radio frequency channel can simplify the circuit structure of the low-power wake-up receiver and reduce the circuit area. Reusing the radio frequency channel can also simplify the control process and save control overhead.
[0064] The communication device provided in this application includes multiple radio frequency (RF) channels, such as a first RF channel and at least one second RF channel. These multiple RF channels are typically integrated into a radio frequency integrated circuit (RFIC). Referring to Figure 4, the first RF channel, second RF channel, etc., can be connected to a wake-up modem, a main modem, etc., via an interface circuit. For example, this interface circuit can be a serial-to-parallel / parallel-to-serial converter (SerDes) circuit. The first RF channel and second RF channel are used to perform down-conversion and analog-to-digital conversion on the received RF signals, and then send the processed signals to the main modem or the wake-up modem. Generally, in low-power mode, the main modem is in a sleep state, and only the wake-up modem is in a working state. The wake-up signal can be transmitted from the first RF channel to the wake-up modem. After the main modem is woken up by the wake-up modem, the wake-up modem goes into sleep mode, and the main modem is in a working state. Communication service signals can be transmitted from the first RF channel and second RF channel to the main modem.
[0065] Taking the first radio frequency channel as an example, when the main modem is in sleep mode, the first radio frequency channel is used to downconvert the received first radio frequency signal to obtain a first signal, and transmit the first signal to the wake-up modem. When the main modem is in working mode, the first radio frequency channel is also used to downconvert the second radio frequency signal to obtain a second signal, and transmit the second signal to the main modem.
[0066] In one possible implementation, referring to FIG5, the first radio frequency channel includes a down-conversion unit 111, a radio frequency wake-up signal processing circuit 1141, and a first bypass branch 1142. The down-conversion unit 111 is used to down-convert the received first or second radio frequency signal, for example, down-converting the first or second radio frequency signal to baseband. The radio frequency wake-up signal processing circuit 1141 is used to determine at least one of the following as the first signal: signal amplitude or signal phase. For example, the radio frequency wake-up signal processing circuit 1141 can be an envelope detector. The first bypass branch 1142 can selectively shield the radio frequency wake-up signal processing circuit 1141. For example, when the first radio frequency channel receives the first radio frequency signal, the downconversion unit 111 performs downconversion processing on the first radio frequency signal. The signal after downconversion processing can be processed by the radio frequency wake-up signal processing circuit 1141 and output as the first signal. When the first radio frequency channel receives the second radio frequency signal, the first bypass branch 1142 can shield (bypass) the radio frequency wake-up signal processing circuit 1141, so that the signal processed by the downconversion unit 111 can be output as the second signal without being processed by the radio frequency wake-up signal processing circuit 1141. The first signal can be a wake-up signal, and the second signal can be a communication service signal, thereby enabling the multiplexing of the radio frequency channel for the wake-up signal and the communication service signal.
[0067] The first radio frequency channel also includes an intermediate frequency amplifier 112, an intermediate frequency filter 113, a baseband amplifier 115, an analog-to-digital converter 116, and a digital front end (DFE) 117. The intermediate frequency amplifier 112 is used to amplify the signal after down-conversion by the down-conversion unit 111. The intermediate frequency filter 113 is used to filter the signal amplified by the intermediate frequency amplifier 112. The filtered signal can be processed by the radio frequency wake-up signal processing circuit 1141 or transmitted through the first bypass branch 1142. The baseband amplifier 115 is used to amplify the first signal processed by the radio frequency wake-up signal processing circuit 1141 or the second signal transmitted through the first bypass branch 1142. The analog-to-digital converter 116 is used to perform analog-to-digital conversion on the signal amplified by the baseband amplifier 115 and output a digital signal. The digital processing unit 117 is used to perform noise reduction processing on the digital signal.
[0068] When the main modem is in operation, the second RF channel is used to down-convert the received third RF signal to obtain a third signal and transmit the third signal to the main modem. The structure and principle of the second RF channel are roughly the same as those of the first RF channel. Referring to Figure 6, the second RF channel includes a down-conversion unit 121, an intermediate frequency amplifier 122, an intermediate frequency filter 123, a baseband amplifier 125, an analog-to-digital converter 126, and a digital processing unit 127. Specifically, the down-conversion unit 121 down-converts the received third RF signal to obtain the third signal; the intermediate frequency amplifier 122 amplifies the third signal converted to baseband signal; the intermediate frequency filter 123 filters the signal amplified by the intermediate frequency amplifier 122; the baseband amplifier 125 amplifies the third signal output after filtering by the intermediate frequency filter 123; the analog-to-digital converter 126 performs analog-to-digital conversion on the third signal amplified by the baseband amplifier 125, converting the third signal from an analog signal to a digital signal; and the digital processing unit 127 performs noise reduction processing on the converted digital third signal.
[0069] Referring to Figure 4, the communication device includes an antenna and a radio frequency (RF) front-end. In this embodiment, the portion between the antenna and the RF channel is collectively referred to as the RF front-end. For example, in this embodiment, referring to Figures 4, 8, and 9, the RF front-end includes a frequency band splitter and an amplifier module.
[0070] The antenna is used to receive radio frequency signals, such as the first radio frequency signal, the second radio frequency signal, and the third radio frequency signal mentioned above. The radio frequency signal can be a multi-carrier carrier aggregation signal. In practical applications, the multi-carrier carrier aggregation method includes at least one of continuous carrier aggregation within a frequency band, discontinuous carrier aggregation within a frequency band, and discontinuous carrier aggregation across frequency bands. The number of antennas can be one or more.
[0071] The input of the band splitter is coupled to the antenna to receive the radio frequency signal output by the antenna and to perform band splitting on the radio frequency signal to obtain at least one frequency band signal and output it. Each frequency band signal may include at least one carrier from multiple carriers. It should be noted that the band splitter in this embodiment may include a duplexer, a tripplexer, a quadplexer, etc. The band splitter shown in Figure 7 can use a surface acoustic wave (SAW) filter and a duplexer to separate signals of multiple frequency bands, such as Band A to Band I. The duplexer is used for frequency division duplexing (FDD) band reception, and the SAW is used for time division duplexing (TDD) band reception. The band splitter shown in Figure 7 is only an example and is not intended to limit the solution provided in the embodiments of this application. In addition, those skilled in the art should know that the coupling mentioned in the embodiments of this invention has a general meaning in the art, including but not limited to direct or indirect connection in an electrical sense. The same applies below and will not be repeated.
[0072] Referring to Figure 8, the communication device includes multiple amplification modules. For example, the communication device includes at least one first amplification module and at least one second amplification module. Different amplification modules can operate in different frequency bands. A frequency band refers to the frequency range of radio frequency signals. Generally, the frequency band below 1 GHz is called the low-frequency band, the frequency band from 1 GHz to 2.2 GHz is called the mid-frequency band, and the frequency band above 2.3 GHz is called the high-frequency band. The low-frequency band includes bands such as B5, B8, B12, and B28; the mid-frequency band includes bands such as B1, B2, B3, B4, B34, and B39; and the high-frequency band includes bands such as B7, B30, B38, and B40.
[0073] Referring to Figure 9, the first amplification module 210 includes a first selection switch 211 and multiple first amplification circuits, such as first amplification circuits 212a, 212b, and 212c. Each first amplification circuit is used to receive a radio frequency signal of one frequency band output by the band splitter. When the main modem is in sleep mode, the first selection switch 211 is used to select to transmit the first radio frequency signal processed by any one of the multiple first amplification circuits to the first radio frequency channel. When the main modem is in working mode, the first selection switch 211 is used to select to transmit the second radio frequency signal processed by any one of the multiple first amplification circuits to the first radio frequency channel, or the first selection switch 211 is also used to select to transmit the third radio frequency signal processed by any one of the multiple first amplification circuits to the second radio frequency channel.
[0074] In one possible implementation, the first selection switch 211 includes multiple input terminals and multiple output terminals. For example, the first selection switch 211 includes: a first input terminal in_A1, a first input terminal in_A2, and a first input terminal in_A3. The multiple first input terminals of the first selection switch 211 correspond one-to-one with multiple first amplifier circuits. Each first input terminal of the first selection switch 211 is connected to the output terminal of the corresponding first amplifier circuit. The first selection switch 211 includes a first output terminal out_A, which is connected to the input interface of the first radio frequency channel.
[0075] When the communication device is operating in low power mode, the first selection switch 211 is used to transmit the first radio frequency signal processed by any of the first amplifier circuits to the first radio frequency channel through the first output terminal out_A, and transmit the first signal to the wake-up modem through the first radio frequency channel. As mentioned in the previous example, the first signal can be a wake-up signal.
[0076] Alternatively, after the wake-up modem wakes up the main modem, the first selection switch 211 can also transmit the second radio frequency signal processed by any of the first amplifier circuits of the first amplifier module to the first radio frequency channel through the first output terminal out_A, and output the second signal to the main modem through the first radio frequency channel. The second signal can be a communication service signal.
[0077] The communication device includes multiple radio frequency channels. In addition to a first radio frequency channel that multiplexes communication service signals and wake-up signals, it also includes at least one second channel. The second channel is used to downconvert a third radio frequency signal to obtain a third signal and transmit the third signal to the main modem. The third signal may be a communication service signal.
[0078] The first selection switch 211 also includes multiple second output terminals, such as second output terminal out_B1, second output terminal out_B2 and second output terminal out_B3. The multiple second output terminals of the first selection switch 211 are respectively connected to multiple second radio frequency channels. The first selection switch 211 can transmit the third radio frequency signal processed by any of the first amplifier circuits of the first amplifier module to the designated second radio frequency channel, and output the third signal to the main modem through the second radio frequency channel. The third signal can be a communication service signal.
[0079] The second amplification module 220 includes a second selection switch 221 and multiple second amplification circuits, such as second amplification circuits 222a, 222b, and 222c. Each second amplification circuit is used to receive a radio frequency signal of one frequency band output by the band splitter. The second selection switch 221 includes a first input terminal in_A1, a first input terminal in_A2, and a first input terminal in_A3. The multiple first input terminals of the second selection switch 221 correspond one-to-one with the multiple second amplification circuits. Each first input terminal of the second selection switch 221 is connected to the output terminal of the corresponding second amplification circuit. The second selection switch 221 includes a first output terminal out_A, a second output terminal out_B1, a second output terminal out_B2, and a second output terminal out_B3. The first selection circuit 211 also includes a second input terminal in_B. The first output terminal out_A of the second selection circuit 221 is connected to the second input terminal in_B of the first selection circuit 211. The multiple second output terminals of the second selection circuit 221 are respectively connected to multiple second radio frequency channels.
[0080] When the communication device operates in low-power mode, and the main modem is in sleep mode, the second amplifier module 220 can share part of the transmission path with the first amplifier module 210. The first selection switch 211 and the second selection switch 221 are used to change the connection mode of the first amplifier module 210 and the second amplifier module 220 to output any first radio frequency signal processed by any second amplifier circuit to the first radio frequency module. For example, when the first amplifier module 210 transmits a second radio frequency signal to the first radio frequency channel, transmits a third radio frequency signal to the second radio frequency channel, and the second amplifier module transmits a third radio frequency signal to the second radio frequency channel, it can be understood that the first amplifier module 210 and the second amplifier module 220 are in parallel. However, when the communication device operates in low-power mode, for example, when the second amplifier module 220 outputs a first radio frequency signal to the first radio frequency channel, the second selection switch 221 can transmit any first radio frequency signal processed by any second amplifier circuit of the second amplifier module 220 to the second input terminal in_B of the first selection switch 211. Its second input terminal in_B is connected to the first output terminal out_A, which means that the first signal processed by the second amplification module 220 is transmitted to the first radio frequency channel. At this time, the first amplification module 210 and the second amplification module 220 are connected in series with respect to the first radio frequency channel, realizing the multiplexing of the transmission path between the first amplification module 210 and the second amplification module 220 and the first radio frequency channel, as shown in Figure 9. The second amplification module 220 uses the first selection switch 211 of the first amplification module 210 as the transmission path of the first radio frequency signal. The second amplification module 220 is connected to the first radio frequency channel through the first selection switch 211, which can reduce port occupation.
[0081] When the main modem is in operation, the second selection switch 221 is used to transmit the third radio frequency signal processed by any one of the multiple second amplifier circuits to the second radio frequency channel.
[0082] For example, the first amplification module 210 can operate in the mid-frequency band, and the second amplification module 220 can operate in the low-frequency band. The frequency difference between the two is small, so the connection relationship between the first amplification module and the second amplification module can be changed by the first selection switch and the second selection switch, and a wake-up signal can be output through the same port.
[0083] If the communication device also includes another amplifier module operating in the high-frequency band, since the signal frequency difference between the high-frequency band and the medium and low-frequency bands is large, it is often not connected in series with the amplifier module operating in the low-frequency or medium-frequency bands, and outputs the first radio frequency signal to the first radio frequency channel independently.
[0084] For example, referring to Figure 10, in one possible implementation, the communication device includes amplification module 210, amplification module 220A, and amplification module 220B. The first radio frequency channel includes a first input interface and a second input interface. The first input interface and the second input interface can be time-division multiplexed. Amplification module 210 and amplification module 220A are used to transmit the first radio frequency signal to the first input interface of the first radio frequency channel; amplification module 220B is used to transmit the first radio frequency signal to the second input interface of the first radio frequency channel. This can reduce the occupation of the radio frequency channel, and the transmission of the first radio frequency signal can be realized by multiplexing only one radio frequency channel.
[0085] For any of the amplifier circuits in the above amplifier module, there are an amplification branch and a bypass branch. The amplification branch is used to amplify the signal, and the bypass branch is used to shield (bypass) the amplification branch to achieve the output of the unamplified signal.
[0086] For example, referring to Figure 11, taking the first amplifier circuit as an example, the first amplifier circuit includes an input terminal IN, an amplification branch 2121, a bypass branch 2122, and an output terminal OUT. The signal gain of the bypass branch 2122 is smaller than that of the amplification branch 2121. The input terminal IN of the first amplifier circuit is used to connect to the output terminal of the frequency band splitter, and the output terminal OUT of the first amplifier circuit is used to connect to the input terminal of the first switching switch 211. When the communication device is operating in low-power mode, the first amplifier circuit can transmit radio frequency signals through the bypass branch 2122. At this time, the bypass branch 2122 can shield (bypass) the amplification branch 2121 to achieve unamplified signal output, that is, the signal is not processed through the amplification branch 2121. After the wake-up modem wakes up the main modem according to the first signal, the first amplifier circuit is used to process and transmit radio frequency signals through the amplification branch 2121. The amplification branch 2121 is equipped with an amplifier, such as a low-noise amplifier, which can be used to amplify the radio frequency signal to meet the processing requirements of communication service signals.
[0087] For example, the bypass branch 2122 may include an adjustable impedance network, such as a π-type network, which can be used to adjust the insertion loss or gain of the bypass branch, such as adjustable insertion loss levels like 0dB / -3dB / -6dB.
[0088] As can be seen from the above examples, in the RF front-end section, the wake-up signal and communication service signal can reuse the amplifier circuit. In low-power mode, the amplifier circuit transmits the wake-up signal through the bypass branch. After the main receiver is woken up, the amplifier circuit can transmit the communication service signal through the amplification branch. In this way, the wake-up signal and communication service signal can be reused in the RF front-end section, which also simplifies the circuit structure and reduces circuit area and cost. In addition, when the main modem is in sleep mode, the connection relationship of the first amplifier module and the second amplifier module can be changed by the selection switch of the first amplifier module, etc. The first RF signal output by different amplifier modules can reuse the first RF channel. For example, the first amplifier module and the second amplifier module can be configured in series by the selection switch of the first amplifier module, so that the first RF signal processed by any amplifier circuit in the second amplifier module can be transmitted to the first RF channel through the first amplifier module, which can reduce the port resources occupied by the first RF channel.
[0089] The communication device provided in this application includes a main modem and a wake-up modem. Referring to FIG12, in one possible example, the main modem is disposed in the baseband chip, and the wake-up modem can be integrated into the radio frequency chip. The radio frequency chip can be connected to the baseband chip through SerDes.
[0090] Since the wake-up modem operates in a low-power mode, to further reduce power consumption, the wake-up modem can be connected to the main modem through a low-speed interface, such as, but not limited to, general-purpose input / output (GPIO).
[0091] In another possible example, referring to Figure 13, the wake-up modem and the main modem can be integrated into the baseband chip, and multiple RF channels can be integrated into the RF chip. The baseband chip and the RF chip can be connected through the SerDes interface.
[0092] In the above embodiments, a radio frequency wake-up signal processing circuit is provided in the first radio frequency channel to extract at least one of the amplitude and phase information of the first radio frequency signal as a first signal. Compared with traditional radio frequency chips, the radio frequency channel in the RFIC needs to be improved. In another possible implementation, the embodiments of this application can also completely reuse traditional radio frequency chips, and set the wake-up signal processing circuit in the baseband chip.
[0093] For example, in this case, the structure of the first radio frequency channel is the same as that of the second radio frequency channel, including a downconversion unit, an intermediate frequency amplifier, an intermediate frequency filter, a baseband amplifier, an analog-to-digital converter, and a digital processing unit. The structure of the second radio frequency channel has been described in the foregoing embodiments and will not be described in detail here.
[0094] The communication device also includes a baseband wake-up signal processing circuit, which is integrated with the wake-up modem and the main modem in the baseband chip.
[0095] The baseband wake-up signal processing circuit is used to receive the first digital signal transmitted by the first radio frequency channel, process the first signal to obtain at least one of amplitude and phase information, and wake up the modem to determine whether the first signal is a wake-up signal based on at least one of the amplitude and phase information of the first signal, and wake up the main modem if the first signal is determined to be a wake-up signal.
[0096] Based on this, the communication device provided in the embodiments of this application can reuse traditional radio frequency chips, thereby reducing costs.
[0097] The communication device provided in this application embodiment also uses the wake-up modem to control the switching of the selection switch of the amplifier module, the switching of the radio frequency channel, etc., and can also adjust the gain of the amplifier circuit. The control methods include RFIC digital IO interface control or GPIO control, etc.
[0098] For example, in low-power mode, the wake-up modem can control the state of the selection switches for the first and second amplifier modules. The wake-up modem can pre-store control channels and digital logic instructions for each frequency band. For instance, when initiating wake-up signal monitoring for Band A, it can control the relevant selection switches and toggle switches to switch their on / off states to receive the wake-up signal from the Band A band. The master modem can inherit the previous RF channel configuration based on the wake-up modem's state before sleep. For example, if the wake-up modem receives the Band A wake-up signal, the master modem, after being woken up, can first receive the Band A communication service signal. This saves system response latency and allows for a quick switch to the master communication mode. Because the wake-up modem and master modem reuse RF channels, RF calibration and RF channel configuration are fully reused, greatly saving calibration costs and control data storage overhead.
[0099] Furthermore, the amplification circuits and selection switches of the aforementioned amplification modules can be integrated or discrete components. For example, the amplification circuits, selection switches, and antenna switches of the first and second amplification modules can be separate components, or they can be integrated with the power amplifiers on the transmitting side to form different front-end module forms such as low-frequency (LB) integrated RF power amplifiers, duplexers, RF switches, and low-noise amplifiers (LNA - Power Amplifier Module integrated Duplexer, L-PAMID), MHB L-PAMID, UHB L-PAMID, or low-frequency integrated RF low-noise amplifiers, RF switches, and filters (LB L-DiFEM), LMHB L-DiFEM, UHB L-DiFEM, etc.
[0100] For example, referring to Figure 14, which shows a schematic diagram of the structure of an LB L-PAMID, the LB L-PAMID integrates an amplifier module, an antenna switch, a frequency band splitter, and a power amplifier on the transmitting side that operate in the low-frequency band. The amplifier module includes a selection switch, which has a reserved output terminal for outputting a first radio frequency signal.
[0101] Figure 15 shows a schematic diagram of an MHB L-PAMID. The MHB L-PAMID integrates an amplification module, antenna switch, frequency band splitter, and power amplifier on the transmitting side, which operate in the mid-to-high frequency range. The amplification module includes a selection switch with a reserved output terminal for outputting a first radio frequency (RF) signal and an reserved input terminal for receiving the first RF signal transmitted by the LB L-PAMID. Thus, the MHB L-PAMID can output the first RF signal processed by the MHB L-PAMID itself to the first RF channel, or it can change the connection relationship between the MHB L-PAMID and the LB L-PAMID, so that the MHB L-PAMID outputs the first RF signal processed by the LB L-PAMID to the first RF channel.
[0102] Figure 16 shows a schematic diagram of a UHB L-PAMID, which integrates an amplifier module, antenna switch, frequency band splitter, and power amplifier on the transmitting side that operate in the ultra-high frequency band. Its selection switch has a reserved output terminal for outputting the first radio frequency signal.
[0103] Figure 17 shows a schematic diagram of an LMHB L-DiFEM. The LMHB L-DiFEM can integrate amplifier modules, frequency band splitters, antenna switches, and selection switches that operate at low and medium-high frequencies respectively. The LMHB L-DiFEM can reserve an output terminal, which, in conjunction with the switching switch, is used to output the first radio frequency signal processed by the low-frequency amplifier module or the first radio frequency signal obtained by the medium-high frequency amplifier module.
[0104] Furthermore, amplification modules for different frequency bands can be configured separately or integrated. For example, the second amplification module can be connected in series with the first amplification module to output the first radio frequency signal; therefore, the second amplification module can be integrated with the first amplification module.
[0105] The communication device provided in this application embodiment can be applied to the receiving channel of the main set, or to the receiving channel of the diversity set, or to both the receiving channels of the main set and the diversity set. This application embodiment does not limit this.
[0106] This application also provides a communication method applied to the above-mentioned communication device. Referring to FIG18, FIG18 shows a schematic flowchart of the communication method provided in this application embodiment. The communication method includes S10 to S40.

[0108] S20: The wake-up modem performs the first parsing process on the first signal and wakes up the main modem if the first signal is a wake-up signal.
[0109] S30: The first radio frequency channel down-converts the second radio frequency signal to obtain a second signal, and transmits the second signal to the main modem. For example, after the main modem is woken up, the first radio frequency channel is also used to transmit the second signal to the main modem.
[0110] S40: The main modem performs a second parsing process on the second signal, which is a communication service signal.
[0111] In the communication method provided in this application embodiment, the first radio frequency channel can process the first radio frequency signal to obtain a first signal and transmit the first signal to the wake-up modem; or it can process the second radio frequency channel to obtain a second signal and transmit the second signal to the main modem. The first signal can be a wake-up signal and the second signal can be a communication service signal. Thus, the wake-up signal and the communication service signal can reuse the radio frequency channel, which can simplify the structure of the communication device, reduce costs, and reduce circuit area.
[0112] The communication device also includes a second radio frequency channel. In one possible implementation, referring to Figure 19, the communication method further includes:
[0113] S50: At least one second radio frequency channel downconverts the third radio frequency signal to obtain a third signal and transmits the third signal to the main modem.
[0114] S60: The main modem performs a second parsing process on the second and third signals, which are communication service signals.
[0115] S30 and S50 have no logical order; S30 can come first, or S50 can come first, or the two can be performed simultaneously.
[0116] For example, the communication device provided in the embodiments of this application can also apply carrier aggregation, and the second signal and the third signal can each include one of the multiple carriers, and the main modem can perform a second parsing process on the second signal and the third signal.
[0117] For example, prior to step S10, the communication method further includes:
[0118] S01: The first selection switch transmits the first radio frequency signal processed by any one of the multiple first amplifier circuits in the first amplifier module to the first radio frequency channel.
[0119] S02: The first selection switch and the second selection switch change the connection method of the first amplification module and the second amplification module, and output the first radio frequency signal.
[0120] For example, S10: The first radio frequency channel downconverts the first radio frequency signal to obtain the first signal, which may include:
[0121] S101: The downconversion unit downconverts the first radio frequency signal;
[0122] S102: The radio frequency wake-up signal processing circuit determines at least one of the following as the first signal: signal amplitude or signal phase.
[0123] In another possible implementation, the wake-up signal processing circuitry can be located in the baseband. For example, the communication method also includes:
[0124] S70: The baseband wake-up signal processing circuit processes the first signal to obtain at least one of the following: signal amplitude or signal phase, which is used for the first parsing process.
