Description

Communication device and its radio hardware configuration setting method

The present invention relates to radio frequency hardware configurations for communication devices, and more particularly to techniques for supporting multiple RF hardware configuration settings through a single software.

In the production line of communication devices (such as mobile phones, smart phones, etc.), it is usually necessary to download the appropriate software version to the communication device corresponding to the hardware configuration of the communication device for related hardware configuration settings, such as setting calibration. Parameters, etc. However, since the same manufacturer usually has different hardware configuration communication device products, different hardware configurations correspond to different software versions. For example, due to the different 3G frequency bands in different countries or regions, the same manufacturer usually produces communication device products with the same appearance but different RF hardware configurations. Therefore, it may happen that the wrong software version is downloaded to the communication device. In this case, the related settings of the communication device will not function properly because the downloaded software is the wrong software. In addition, in the case where the software download error is not known, it is very likely that the communication device that is not functioning properly will be returned to the production department to clarify the problem, so as to increase the production cost. Although the current technology will reduce the chances of downloading the wrong software version through the production line control, but different software versions need to have their own quality control process. When the software version is more, in addition to the complexity of the control, the product is also added. The time of the process. In addition, when the communication device fails and is sent back for repair, it is usually necessary to disassemble the outer casing of the communication device, and confirm the radio frequency hardware configuration by scanning the barcode attached to the chip, thereby increasing maintenance difficulty and inconvenience.

In view of the above, the present invention detects the RF hardware configuration of the communication device through a detection mechanism, and performs RF hardware configuration setting corresponding to the RF hardware configuration, so that multiple RF hardware configurations can be supported by a single software. set up.

[First Embodiment]

Fig. 2 is a schematic view showing a communication device 2 according to a first embodiment of the present invention. The communication device 2 includes a baseband processing unit 20, a radio frequency unit 22, and an antenna 24. The baseband processing unit 20 includes a micro control unit 210, a general purpose input/output (hereinafter referred to as GPIO) controller 220, and a GPIO port 222. The GPIO controller 220 receives the configuration set value CSV1 through the GPIO port 222 and transmits the configuration set value CSV1 to the micro control unit 210. The micro control unit 210 determines the radio frequency hardware configuration of the communication device 2 according to the configuration setting value CSV1, and correspondingly performs radio frequency hardware configuration setting. In the present embodiment, the configuration set value CSV1 is a voltage value. For example, before the communication device 2 is shipped from the factory, the corresponding resistors R1 and R2 are selected according to the RF hardware configuration of the communication device 2 and configured in the communication device 2 The partial voltage formed by the resistors R1 and R2, that is, the configuration set value CSV1, is coupled to the GPIO port 222 of the baseband processing unit. For example, when the communication device 2 is configured for the first RF hardware (supporting Band 1 and Band 8), the resistor R1 is high resistance and the resistor R2 is short-circuited, and when the communication device 2 is configured for the second RF hardware ( When band 2 and band 5) are supported, resistor R1 is shorted and resistor R2 is high. For example, shorting the resistor R1 or R2 means using a zero ohm resistor (ie, a resistor with a very small resistance). Alternatively, although a zero ohm resistor is not used, a resistor (for example, a 1K or 2K ohm resistor) that allows the generated configuration set value CSV1 to be 0 or 1 level is used. Therefore, after the communication device 2 is powered on, the GPIO controller 220 receives the configuration set value CSV1 through the GPIO port 222 and transmits the configuration set value CSV1 to the micro control unit 210. The micro control unit 210 then performs radio frequency hardware configuration setting on the radio frequency unit 22 according to the configuration setting value CSV1. It should be noted that the communication device of FIG. 2 is merely an example and is not intended to limit the present invention. For example, the baseband processing unit may further include a digital signal processor, a digital to analog converter, and the like.

When the configuration set value CSV1 is low (for example, the resistor R1 is high resistance and the resistor R2 is short-circuited), the micro control unit 210 determines that the communication device 2 is configured as the first radio frequency hardware, that is, the communication device 2 supports the frequency band 1 and the frequency band. 8 communication device, so the micro control unit 210 performs corresponding RF hardware configuration settings according to the first RF hardware configuration, as shown in FIG. 3a.

The RF module 321A includes receiving inputs RX1 R RX6 and transmitting outputs T1 TX1 TX4. Since the radio frequency unit 32A supports the frequency band 1 and the frequency band 8, the respective receiving signals and transmission signals of the frequency band 1 and the frequency band 8 must be set to the appropriate receiving input port and transmission output port to connect to the appropriate receiving path and transmission path, and avoid the signal. Interference between. As shown in FIG. 3a, the micro control unit 210 sets the receiving input RX2 to receive the signal of the frequency band 1 according to the first radio frequency hardware configuration, and the receiving input RX6 is set to receive the signal of the frequency band 8, and the transmission output TX2 is set to The signal of the transmission band 1 and the transmission output 埠 TX3 are set to transmit the signal of the frequency band 8.

When the configuration set value CSV1 is high (for example, the resistor R1 is short-circuited and the resistor R2 is high-resistance), the micro control unit 210 determines that the communication device 2 is configured as the second RF hardware, that is, the communication device 2 supports the frequency band 2 and the frequency band. 5 communication device, so the micro control unit 210 performs corresponding RF hardware configuration settings according to the second RF hardware configuration, as shown in FIG. 3b. Figure 3b is a schematic diagram of RF hardware configuration settings for the RF unit 32B in accordance with the second RF hardware configuration. The radio frequency unit 32B includes a radio frequency module 321B, an antenna switching module 322B coupled to the antenna 34B, a frequency band 2 duplexer 323B coupled to the antenna switching module 322B, and a frequency band 5 duplexer 325B for The frequency band 2 amplifier 324B of the signal power before the transmission of the frequency band 2 is transmitted, and the frequency band 5 amplifier 326B for amplifying the signal power before transmitting the signal of the frequency band 5. The RF module 321B includes receiving inputs RX1 R RX6 and transmitting outputs 埠 TX1 〜 TX4. Since the radio frequency unit 32B supports the frequency band 2 and the frequency band 5, the respective reception signals and transmission signals of the frequency bands 2 and 5 must be Set to the appropriate receive input and transmit output to connect to the appropriate receive and transmit paths and avoid interference between signals. As shown in FIG. 3b, the micro control unit 210 sets the receiving input RX1 to receive the signal of the frequency band 2, the receiving input, the RX4 is set to the signal of the receiving frequency band 5, and the transmission output 埠TX1 is set according to the second RF hardware configuration.
