Description

Technical Field

[0001] This invention belongs to the field of wireless communication technology, and particularly relates to a 5G-based spaceborne base station plus phased array antenna environment, especially a method to reduce power consumption by dynamically shutting down the radio frequency channel of the phased array antenna. Background Technology

[0002] Existing power reduction technologies for phased array antennas mainly achieve this through optimizing RF power amplifier efficiency, improving IC integration, and employing new materials and packaging technologies. The specific technical directions are as follows: RF power amplifier efficiency optimization: Equal power density output method: By dynamically adjusting the attenuation value of the RF branch, the RF power amplifier is always kept at the saturation operating point, reducing power waste.

[0003] Gallium nitride (GaN) power amplifiers: Compared with traditional GaAs technology, GaN devices have higher power density in the X-band and a footprint that is reduced by more than 50%, significantly reducing power consumption and heat dissipation requirements.

[0004] Integrated circuits and packaging technology: Highly integrated ICs: Employing technologies such as SiGe BiCMOS and SOI, digital control, memory, and RF transistors are integrated into a single chip, reducing power consumption of peripheral circuits.

[0005] Multi-chip module (MCM): By integrating MMIC devices and passive components, the package size and power consumption are reduced, while heat dissipation is optimized by using thermal vias or copper scrap.

[0006] Array design optimization: Flat panel architecture: Replaces the traditional PCB board structure, reduces circuit board depth and power consumption, and is suitable for portable and airborne devices.

[0007] Low-profile arrays: reduce overall power consumption by decreasing component spacing and optimizing thermal management.

[0008] Other technologies: Dynamic beamforming: reduces unnecessary radiation energy, indirectly reducing power consumption.

[0009] Low-power ADC / DAC: Optimized data converter power consumption for large-scale arrays.

[0010] Problems with the aforementioned existing technology: 1. Optimizing RF power amplifier efficiency and dynamically adjusting attenuation values ​​require complex control circuits, increasing system complexity. Heat dissipation becomes a significant issue in high-power scenarios, impacting long-term reliability.

[0011] 2. Highly integrated IC and packaging technologies, especially hybrid heterogeneous integration, may lead to signal interference, requiring additional shielding design. Multiphysics coupling models at the micro-nano scale are not yet fully mature, affecting performance stability.

[0012] 3. Dynamic beamforming requires an independent ADC / DAC for each array element, leading to an exponential increase in hardware costs with scale. Real-time data processing places extremely high demands on chip computing power, making it difficult to balance power consumption and performance.

[0013] 4. Application of novel materials: Gallium nitride (GaN) and other materials have high processing costs and low yields in mass production. Liquid crystal materials require a large number of bias lines for control, making large-scale array implementation difficult.

[0014] 5. Low-power ADC / DAC technology: High-resolution ADCs (such as 14 bits and above) are expensive and require signal conditioning circuitry. Dual-slope ADCs have low conversion rates and cannot meet the needs of high-speed applications.

[0015] The common problems with existing technologies are: technical complexity is positively correlated with cost, especially in large-scale arrays. Issues such as heat dissipation and electromagnetic compatibility affect engineering applications. Summary of the Invention

[0035] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0036] This embodiment discloses a method for reducing power consumption by dynamically shutting down the radio frequency channel of a phased array antenna, including: After receiving instructions from the ground network management system and enabling the dynamic shutdown function, the algorithm scheme is configured based on the received instruction information. Based on the configured algorithm, network load parameters are periodically acquired at a preset time granularity. Based on the currently acquired network load parameters, the value of the shutdown control parameter n is determined according to preset decision conditions; The number of RF channels D to be turned off is calculated based on the value of the shutdown control parameter n; Send a command to the phased array antenna to shut down D radio frequency channels.

[0037] Specifically, such as Figure 1 As shown, a method for reducing power consumption by dynamically shutting down the radio frequency channels of a phased array antenna includes: Step 1, Function Activation: The ground network management system sends a command to the satellite baseband to turn on the dynamic antenna channel shutdown switch and instructs the satellite base station to configure the algorithm scheme. The instruction message includes a first instruction, a second instruction, or a dynamic selection instruction: the first instruction corresponds to algorithm scheme one, the second instruction corresponds to algorithm scheme two, and the dynamic selection instruction corresponds to the dynamic selection scheme.

[0038] Step 2: The onboard base station determines the switching status of the dynamically disabled antenna channels. If the switch is on, the process proceeds to the next step to determine the algorithm scheme; if the switch is off, the base station stops the query task and issues a command to restore the phased array antenna channel switching status to the initial state. The initial state is when all radio frequency channels of the phased array antenna are on (i.e., normal operation).

[0039] Step 3: The satellite base station determines the algorithm scheme. If the satellite base station receives the first instruction, it configures Scheme 1 and starts querying the current number of users in the cell in real time at a 5-minute granularity. If the satellite base station receives the second instruction, it configures Scheme 2 and starts querying the uplink PRB utilization rate and downlink PRB utilization rate in real time at a 10-minute granularity. After obtaining the query data, the satellite base station stops real-time query monitoring. If the satellite base station receives the dynamic selection instruction, it configures the dynamic selection scheme and automatically switches between Scheme 1 and Scheme 2 according to the dynamic selection scheme algorithm.

[0040] Option 1: In the initial stage of satellite communication network deployment, when the number of online users is less than 100 or the cell's service load is less than 50%, the value of n can be determined based on the number of users in the cell, with the following decision conditions: When 0 When <20, n=2; When 20 When <50, n=1; when When n=50, n=0.

[0041] The number of users in the cell is represented by the satellite base station or satellite general computing component, which counts the number every 5 minutes with a granularity. When the number of users in the cell meets the above conditions, the value of n is determined and an adjustment command is sent to the phased array antenna.

[0042] This embodiment uses an S-band phased array antenna as an example. The antenna array consists of 11 subarrays, each containing 48 transmit and receive channels, for a total of 1056 transmit and receive channels across the entire array.

[0043] when When the value of n is less than 20, the value of n is 2, and D is calculated to be 792, meaning 792 antenna RF channels are shut down. Redundant channels are prioritized for shutdown, and can be shut down sequentially from high to low based on traffic load, theoretically reducing antenna power consumption by 75%. Specific channel shutdown measures are determined based on antenna implementation and considerations that minimize the impact on overall performance.

[0044] when When n is greater than or equal to 20 and less than 50, the value of n is 1, and D is calculated as 528, which means that 528 antenna RF channels are turned off, which can theoretically reduce antenna power consumption by 50%.

[0045] when When the value is greater than or equal to 50, the value of n is 0 and D is 0, that is, the antenna RF channel is not turned off. If there is a closed RF channel, the closed RF channel will be turned on. At this time, the antenna is in a state where all 1056 RF channels are operating normally.

[0046] Option 2: In the later stages of satellite communication network deployment, when the number of online users exceeds 100 or the cell service load exceeds 50%, the value of n is determined based on the uplink PRB utilization rate and downlink PRB utilization rate, with the following decision conditions: 0 When <30%, n=2; 30% When <50%, n=1; When the percentage is 50%, n=0.

[0047] The uplink or downlink PRB utilization rate is queried by the satellite base station or satellite general computing component in 10-minute increments. When the uplink and downlink PRB utilization rates meet the above conditions, the value of n is determined to calculate the number of radio frequency channels to be shut down.

[0048] when When it is less than 30%, the value of n is 2. When the percentage is greater than or equal to 30% and less than 50%, the value of n is 1. When the percentage is greater than or equal to 50%, the value of n is 0, and the number of RF channels turned off is [number missing]. The calculations and theoretical reductions in power consumption are the same as in Scheme 1.

[0049] Dynamic scheme selection: The satellite base station automatically switches to Scheme 1 or Scheme 2 based on the judgment conditions of Scheme 1 and Scheme 2. The switching protection time is set to 15 minutes. The timer starts after the scheme is switched and no scheme switching is performed during the switching protection time.

[0050] Step 4: Data Calculation. The satellite base station uploads the queried data (number of users or PRB utilization rate) to the satellite general computing component for calculation. The satellite general computing component determines the value of n and calculates the number of radio frequency channels to be shut down, D, according to the algorithm and sends it back to the satellite base station (if the satellite base station has sufficient resources, the calculation module can be moved forward, and the satellite base station can directly complete the calculation based on the queried data).

[0051] The formula for the number of radio frequency channels D is: Where D is the result of the calculation, rounded down; X is the total number of adjustable RF channels for the antenna.

[0052] Step 5: The satellite base station first determines the specific shutdown strategy (such as shutting down the corresponding numbered channel) based on the calculated number of radio frequency channels D to shut down, and then sends an adjustment command containing this strategy to the phased array antenna.

[0053] Step 6: The phased array antenna executes the command. The phased array antenna opens or closes the corresponding radio frequency channel according to the command of the satellite base station, and feeds back the status of all channels after execution to the satellite base station. The satellite base station records the current antenna channel status.

[0054] This implementation can be achieved using software, making it highly feasible and cost-effective.
