Description

Technical Field

[0001] This invention belongs to the field of wireless communication technology, specifically a low-power anti-interference LTE Cat1 multimode wireless communication module system. Background Technology

[0002] The low-power, interference-resistant LTE Cat1 multimode wireless communication module is a highly integrated wireless communication solution designed for low-to-medium speed Internet of Things (IoT) applications. It supports multiple cellular network standards, including GSM, WCDMA, and LTE Cat1, and significantly reduces system power consumption and sensitivity to external interference while ensuring communication reliability. This module is widely used in terminal products such as smart meters, asset tracking, industrial monitoring, and wearable devices, which have stringent requirements for cost, power consumption, and connection stability. It is a key hardware foundation for achieving wide-area IoT connectivity.

[0003] The module integrates baseband processing, multi-mode RF transceiver, power management, anti-interference processing, and multi-network collaborative control functions through a highly integrated single-package architecture. Its working principle mainly includes: a RISC-based baseband processor dynamically starts and stops protocol stack sub-modules according to the currently active communication standard and service type to reduce redundant calculations; the RF front-end employs impedance self-matching and tunable filtering technology to enable multiple frequency bands (GSM / WCDMA / LTE Cat1) to share the same path; adaptive power management dynamically adjusts voltage and clock based on network status and signal quality, and supports tiered sleep mode; the anti-interference module suppresses continuous wave interference through analog domain interference detection and digital domain adaptive notch filtering.

[0004] However, existing technologies still have many shortcomings in implementing multimode cellular communication modules: First, traditional multimode solutions typically employ discrete RF front-end designs, requiring independent power amplifiers, filters, and matching networks for different standards, resulting in large chip areas, high BOM costs, and complex reconfiguration during frequency band switching, making it difficult to meet miniaturization and low power consumption requirements; Second, existing baseband processors mostly adopt fixed protocol stack architectures, running the protocol layer in full regardless of service load, causing a large amount of invalid computation and significantly increasing static and dynamic power consumption, which is detrimental to long-standby IoT devices; Third, facing narrowband continuous wave interference in complex electromagnetic environments (such as co-channel interference from Wi-Fi, Bluetooth, or industrial equipment), traditional receivers lack real-time sensing and dynamic suppression capabilities, often relying on external filters or sacrificing sensitivity to cope, affecting communication reliability and failing to achieve effective anti-interference without increasing hardware complexity; These problems severely restrict the large-scale application of multimode communication modules in low-cost, low-power, and highly robust IoT terminals; Therefore, a low-power anti-interference LTECat1 multimode wireless communication module system is proposed to address these issues. Summary of the Invention

The multi-network standard collaborative control unit is communicatively connected to the integrated baseband processing unit. It has a built-in network selection strategy engine and is configured to initiate a handover between multiple available network standards based on signal strength, operator priority, and historical connection stability. Before the handover, the integrated baseband processing unit caches the current radio resource control status, security context identifier, and IP session parameters in a non-volatile storage area to restore the connection in the target network without having to re-execute the complete authentication process.

[0007] Preferably, when there is no user plane data transmission but the network registration state needs to be maintained, the integrated baseband processing unit disables the physical layer and media access control layer processing logic corresponding to the non-currently active standard by the configurable protocol stack execution engine, while retaining the operation of the radio resource control state machine, so as to reduce baseband processing power consumption and support rapid communication recovery.

[0010] Preferably, the anti-interference signal processing module includes a continuous wave interference detection circuit and an adaptive notch filter; The continuous wave interference detection circuit is configured to monitor the spectrum of the received signal in real time, and when continuous wave interference is detected, output the center frequency information corresponding to the interference. The adaptive notch filter adaptively configures one or more notch frequencies in the digital baseband domain according to the center frequency information to form an amplitude suppression zero at the corresponding frequency point, thereby suppressing the continuous wave interference.

[0011] Preferably, the network selection strategy engine in the multi-network standard collaborative control unit sorts available networks and selects the target standard based on the following comprehensive scoring function: in, For the first A rating of available networks, Its received signal strength The maximum RSSI value across all available networks. The operator priority weight corresponding to this network , The reliability factor is calculated based on historical connection stability. , , For pre-configured weighting coefficients and satisfying The network selection strategy engine selects the network with the highest score as the switching target.

[0012] Preferably, the adaptive power management module dynamically adjusts the operating voltage according to the current communication status. With clock frequency Its adjustment strategy satisfies the following power consumption optimization constraints: in, The total power consumption of the system is It is an equivalent switched capacitor. These are process-related constants. This refers to static leakage power consumption; the adaptive power management module, while ensuring data throughput requirements, reduces [the power consumption] by [reducing the leakage current]. And reduce proportionally at the same time ,make Minimize, and No lower than the current Minimum stable supply voltage required .

[0014] Preferably, before triggering the standard switching, the multi-network standard collaborative control unit sends a pre-wake-up command to the adaptive power management module, so that the radio frequency transceiver link and baseband processing resources of the target standard enter the preparation state in advance. The integrated baseband processing unit reuses the cached authentication and session context during the switching process.

[0015] Preferably, the integrated baseband processing unit, multi-mode RF transceiver unit, adaptive power management module, anti-interference signal processing module, and multi-network standard collaborative control unit are all integrated in a multi-chip module within the same chip or package. Low-latency data exchange and control command synchronization are achieved through an on-chip interconnect bus, and real-time closed-loop control of the impedance self-matching circuit and RF front-end is supported.

[0016] The beneficial effects of this invention are: This invention provides a low-power, interference-resistant LTE Cat1 multi-mode wireless communication module system. By integrating a broadband reconfigurable power amplifier, an on-chip tunable filter structure, and an impedance self-matching circuit into the multi-mode RF transceiver unit, it enables different operating frequency bands of multiple standards such as GSM, WCDMA, and LTE Cat1 to dynamically share the same RF front-end path. This design achieves high reuse and automatic adaptation of RF hardware, significantly reducing chip area and the number of peripheral components, lowering BOM costs, and avoiding the complex reconfiguration process during frequency band switching. This effectively improves system integration, energy efficiency, and switching response speed.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1-4 The present invention provides a low-power anti-interference LTECat1 multimode wireless communication module system, including an integrated baseband processing unit, a multimode radio frequency transceiver unit, an adaptive power management module, an anti-interference signal processing module, and a multi-network standard collaborative control unit integrated in a single package. The integrated baseband processing unit is implemented based on a reduced instruction set processor architecture and has an embedded configurable protocol stack execution engine. The protocol stack execution engine is configured to dynamically enable or disable the corresponding protocol sublayer modules according to the currently active communication standard and service type, so as to reduce unnecessary computational overhead. The multimode RF transceiver unit includes a broadband reconfigurable power amplifier, a low-noise amplifier, an orthogonal mixer receiving link, and a tunable filter structure integrated in the chip, and is coupled with an impedance self-matching circuit. The impedance self-matching circuit automatically adjusts the matching network parameters in response to the target operating frequency band, so that the multimode RF transceiver unit can share the same RF front-end path in GSM, WCDMA and LTE Cat1 frequency bands. The adaptive power management module is electrically connected to the integrated baseband processing unit and the multimode radio frequency transceiver unit respectively. It is configured to dynamically adjust the operating voltage and clock frequency supplied to each unit according to the network registration status, data transmission activity and received signal quality indicators, and enter a hierarchical sleep mode when there is no data transmission and the network remains registered. The anti-interference signal processing module includes a continuous wave interference detection circuit deployed in the analog receiving link and an adaptive notch filter coupled to the baseband digital receiving end. The continuous wave interference detection circuit outputs interference frequency information to the adaptive notch filter to generate a suppression zero point for the corresponding frequency point in real time. The multi-network standard collaborative control unit is communicatively connected to the integrated baseband processing unit. It has a built-in network selection strategy engine and is configured to initiate a handover between multiple available network standards based on signal strength, operator priority, and historical connection stability. Before the handover, the integrated baseband processing unit caches the current radio resource control status, security context identifier, and IP session parameters in a non-volatile storage area to restore the connection in the target network without having to re-execute the complete authentication process. By employing a highly integrated design, the integrated baseband processing unit, multi-mode RF transceiver unit, adaptive power management module, anti-interference signal processing module, and multi-network standard collaborative control unit are all integrated into a single package (which can be a single-chip SoC or an MCM multi-chip module). High-speed, low-latency data exchange and control command synchronization are achieved through an on-chip interconnect bus. The integrated baseband processing unit is built on a Reduced Instruction Set Computing (RISC) processor architecture and embeds a configurable protocol stack execution engine. This engine can dynamically enable or disable the corresponding protocol sublayer modules according to the currently active communication standard and service type, thereby significantly reducing unnecessary computational overhead and lowering baseband processing power consumption.

[0023] The multimode RF transceiver unit includes a wideband reconfigurable power amplifier (PA), a low-noise amplifier (LNA), a quadrature mixer receiver link, and an on-chip tunable filter structure, coupled with an impedance self-matching circuit. This circuit can automatically adjust the matching network parameters (such as inductor / capacitor values) according to the target operating frequency band, so that the entire RF front end can share the same RF path under GSM (850 / 900 / 1800 / 1900MHz), WCDMA (Band I–VIII), and LTE Cat1 (Band 1 / 3 / 5 / 8 / 20, etc.) frequency bands, avoiding the area and power consumption costs caused by the need to reconfigure the front end due to frequency band switching in traditional multimode solutions.

[0024] The adaptive power management module is electrically connected to the baseband processing unit and the RF transceiver unit respectively, and monitors the network registration status, data transmission activity, and received signal quality indicators (such as RSRP and SINR) in real time. Based on this, the module can dynamically adjust the operating voltage and clock frequency supplied to each unit, and enter a hierarchical sleep mode when there is no data transmission but network registration needs to be maintained, which greatly extends the terminal standby time.

[0025] The anti-interference signal processing module consists of two parts: a continuous wave interference detection circuit deployed in the analog receiving link, used to scan the received spectrum in real time and identify narrowband strong interference frequency points; and an adaptive notch filter coupled to the baseband digital receiver, which receives interference frequency point information from the detection circuit and dynamically generates the corresponding frequency point suppression zero in the digital domain, effectively eliminating the impact of continuous wave interference on demodulation performance without adding extra RF front-end complexity.

[0026] The multi-network standard collaborative control unit and the baseband processing unit communicate via a control bus and have a built-in network selection strategy engine. This engine comprehensively evaluates the signal strength, operator priority, and historical connection stability of multiple available networks, and intelligently initiates handover between different standards. Before handover, the baseband unit caches the current Radio Resource Control (RRC) status, security context identifier, and IP session parameters in a non-volatile storage area, enabling rapid connection recovery in the target network, avoiding the need to re-execute the complete authentication and attach process, significantly reducing handover latency and signaling power consumption.

[0027] Furthermore, such as Figures 1-4 As shown, when the system is in a state of no user plane data transmission but needs to maintain network registration, the configurable protocol stack execution engine in the integrated baseband processing unit will automatically disable the physical layer (PHY) and media access control layer (MAC) processing logic corresponding to the non-currently active standard. For example, if the system is currently camped on an LTE Cat1 network, the PHY / MAC modules for GSM and WCDMA will be completely turned off; and vice versa. Meanwhile, only the Radio Resource Control (RRC) state machine remains continuously running to listen for paging messages and process necessary signaling such as TAU / RAU requests. This mechanism significantly reduces the number of active logic gates in the baseband processor, lowers dynamic power consumption by more than 40%, and ensures that the complete protocol stack can be quickly woken up within milliseconds to resume full-speed communication when downlink data is received or uplink transmission is triggered.

[0028] Furthermore, such as Figures 1-4 As shown, the impedance self-matching circuit consists of a digital control unit, a programmable capacitor array (varactor bank), and a switching inductor network. Its control input is connected to a multi-network collaborative control unit. Once the collaborative control unit determines the target operating frequency band, it immediately sends a frequency band identification signal to the impedance self-matching circuit.

[0029] The circuit automatically adjusts the equivalent impedance of the matching network through internal table lookup or closed-loop feedback algorithm, ensuring that the input / output impedance of the RF front-end is always close to 50Ω, maximizing power transmission efficiency. Since the frequency bands of GSM, WCDMA, and LTE Cat1 partially overlap, this design allows the same RF path (including PA, LNA, switches, and filters) to be multiplexed, eliminating the redundant hardware required in traditional solutions that configure separate front-ends for each standard.

[0030] Furthermore, such as Figures 1-4As shown, when the adaptive power management module determines that the system meets the conditions for entering hibernation, it first sends a hibernation preparation command to the integrated baseband processing unit. The baseband unit then performs a context saving operation: writing key parameters such as the current RRC status, security key context, IP address, and PDN connection ID into the on-chip non-volatile memory area; After being woken up by an external event, the power management module first restores power and clock, and the baseband unit immediately reads the cache context from the non-volatile zone and directly rebuilds the RRC connection and IP session, skipping the complete attach process such as PLMN selection, authentication, security activation, and PDN establishment.

[0031] Furthermore, such as Figures 1-4 As shown, the continuous wave interference detection circuit adopts a method that combines energy detection and spectrum refinement. It scans the spectrum in real time at the analog intermediate frequency (IF) or ADC output of the receiving link. Once a narrowband strong interference is detected, its center frequency fint is immediately extracted and transmitted to the adaptive notch filter through the internal bus. This notch filter is located in the digital baseband receiver link (usually placed before the FFT or after the equalizer). Its null position is dynamically configured according to FINT, forming deep suppression (typically >20dB) at the interference frequency, while having minimal impact on nearby useful signals. The entire process is completed in milliseconds and requires no adjustment of the RF front-end hardware.

[0032] Furthermore, such as Figures 1-4 As shown, the system achieves intelligent network selection through a multi-network standard collaborative control unit. This unit has a built-in network selection strategy engine that can comprehensively evaluate all available communication networks in the current environment (including different frequency bands of GSM, WCDMA, and LTE Cat1) and select the optimal target network for camping or handover.

[0033] The evaluation process takes into account three key factors: The first is signal strength, which refers to the strength of the wireless signals received by the terminal from various networks; the stronger the signal, the more stable the connection quality usually is.

[0034] The second is operator priority, which is predefined by device configuration or user settings. For example, the network of the primary contracted operator will be given higher priority, while the network of roaming or cooperative operators will have lower priority.

[0035] Third is historical connection stability. The system records the actual performance of each network over a period of time, including whether there are frequent disconnections, whether the handover is successful, and whether data transmission is interrupted. The higher the stability of the network, the higher the score.

[0036] The strategy engine weights and combines the three factors mentioned above according to a preset importance ratio to form a comprehensive score. Ultimately, the system selects the network with the highest score as the current connection target. For example, even if the signal of an LTE network is slightly weaker than that of another WCDMA network, the system may still prioritize the LTE network if it belongs to a major operator and has a very stable historical connection.

[0037] Furthermore, such as Figures 1-4 As shown, when the module is under high load, the baseband processing unit and the RF transceiver unit require higher operating voltages and faster clock frequencies to ensure processing power and communication speed. However, once data transmission ends or service demands decrease (e.g., only heartbeat packets need to be maintained or paging needs to be monitored), continuing to maintain high voltage and high frequency operation will result in unnecessary energy waste.

[0038] To this end, the adaptive power management module monitors current metrics such as data throughput, modulation scheme, and coding efficiency in real time. When it determines that the system load is decreasing, it gradually reduces the clock frequency supplied to the baseband and RF units, while simultaneously reducing the operating voltage. This is because the dynamic power consumption of digital circuits is proportional to the square of the voltage, and a small voltage reduction can result in significant energy savings. However, the voltage will not decrease indefinitely; it will always be maintained above the minimum safe threshold for stable chip operation at the current frequency to prevent logic errors or communication failures.

[0039] Furthermore, such as Figures 1-4 As shown, the function of a notch filter is to remove interference components at specific frequency points from the received signal spectrum. Its core characteristics include notch depth (i.e., the strength of interference suppression) and notch bandwidth (i.e., the range of frequencies affected). These two parameters are not fixed, but are dynamically adjusted by the integrated baseband processing unit according to the current communication environment.

[0040] Specifically, when the system detects strong narrowband continuous wave interference in the channel (such as fixed-frequency radiation from nearby electronic devices) and the overall signal-to-noise ratio is low, the baseband unit will instruct the notch filter to deepen the suppression depth, so that it forms a deep and narrow suppression valley at the interference frequency point, thereby eliminating the interference effect to the maximum extent.

[0041] Conversely, when channel conditions are favorable (high signal-to-noise ratio) or the terminal is in a high-speed moving state (such as in vehicle applications), the Doppler effect causes the signal spectrum to broaden. If the notch is too narrow or too deep, it may inadvertently suppress nearby useful signals. In this case, the baseband unit will actively widen the notch bandwidth and appropriately reduce the suppression depth to make the filter more forgiving and avoid negatively impacting normal communication.

[0042] Furthermore, such as Figures 1-4As shown, traditional handover processes typically only activate the target network's hardware and protocol stack after the handover decision is made, resulting in longer interrupt times and higher initialization power consumption. This system, however, employs a pre-preparation strategy: when the multi-network standard collaborative control unit determines that a handover to a target network is necessary (e.g., a fallback to WCDMA due to a deteriorating LTE signal), it immediately sends a pre-wake-up command to the adaptive power management module.

[0043] This instruction triggers the power management module to provide basic power to the target standard's RF transceiver link (such as WCDMA-specific low-noise amplifiers and power amplifiers) and baseband processing resources (such as WCDMA's channel decoder and RRC state machine), enabling it to transition from a completely off state to a low-power standby state, rather than a cold start.

[0044] Meanwhile, the integrated baseband processing unit reads previously cached security keys, IP session information, and radio resource control status from the non-volatile storage area and uses them directly in the new network connection recovery process. This eliminates the need for the system to re-execute time-consuming and power-intensive signaling interactions such as complete network attachment, user authentication, and IP address allocation.

[0045] Furthermore, such as Figures 1-4 As shown, all functional modules—baseband, RF, power management, anti-interference processing, and network control—are integrated into a multi-chip module within the same chip or package. Modules exchange data and control signals via a low-latency on-chip interconnect bus, avoiding parasitic inductance / capacitance, signal reflection, and EMI problems introduced by PCB traces in traditional discrete solutions. Especially for impedance self-matching circuits and the RF front-end, on-chip integration enables microsecond-level closed-loop control, real-time compensation for process deviations and temperature drift.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
