[0026] The communication device 10 of the embodiments of the present application can be applied to a communication system, as shown in FIG. 1, which can include a communication server, a plurality of communication devices 10, and the communication server can be a base station, a router or the like connection site. The communication device 10 of the embodiments of the present application can support communication with the connection site, and can also support communication with other communication devices 10. The communication device 10 of the embodiments of the present application can include a radio frequency module 100 and a power supply module 200. The power supply module 200 can be used to supply power to the radio frequency module 100, and can also be used to supply power to other load devices in the communication device 10 to ensure the normal work of the communication device 10.

[0027] Optionally, as shown in FIG. 3, the power supply module 200 can include a battery module 210, and can also include a power management module 220, which can be used to convert the battery voltage output by the battery module 210 to output a system voltage for various load devices of the communication device 10. Optionally, the power management module 220 can be a power management integrated circuit (PMIC) that integrates multiple power management functions, and can include power management, charging management, battery management, power conversion, etc. functions, which can help improve the power efficiency and performance of the device. Optionally, the battery module 210 can use different battery types according to actual conditions, for example, a graphite battery can be used, and the corresponding battery voltage range of the graphite battery can be 3.3V-4.5V; a silicon negative electrode battery can be used, and the corresponding battery voltage range of the silicon negative electrode battery can be 2.7-4.5V. It can be understood that the battery module 210 can also be other battery types, which will not be described one by one in the present embodiment.

[0028] The radio frequency module 100 of the present embodiment can be used to support communication in a wireless short distance mode, for example, to support transmission processing and reception processing of a radio frequency signal in a wireless short distance mode. Optionally, the wireless short distance mode can include any one of a WIFI mode and a Bluetooth (BT) mode, the WIFI mode can include at least one of a 2.4G WIFI mode and a 5G WIFI mode, and the Bluetooth mode can include at least one of a 2.4G BT mode and a 5G BT mode. In the following embodiments, WIFI mode is mainly used for description. It can be understood that the present application is not limited to the WIFI mode and the BT mode described above, and the present embodiment will not be described one by one.

[0029] In one embodiment, as shown in FIG. 4, the radio frequency module 100 includes a radio frequency transceiver 110, a voltage regulation module 120, and a radio frequency module 130.

[0030] The voltage regulation module 120 is connected with the power supply module 200, and is used to perform voltage reduction processing on the first power supply voltage output by the power supply module 200 to output a second power supply voltage, the second power supply voltage being determined based on the voltage range in which the first power supply voltage is located; the radio frequency module 130 is connected with the radio frequency transceiver 110 and the voltage regulation module 120 respectively, and the radio frequency module 130 is used to perform transmission processing on the wireless short distance mode radio frequency signal to be transmitted output by the radio frequency transceiver 110 under the action of the second power supply voltage.

[0031] The radio frequency module 130 is connected with the radio frequency transceiver 110 and the antenna respectively to receive a radio frequency signal to be transmitted from the radio frequency transceiver 110, and perform a transmitting process on the radio frequency signal to transmit the radio frequency signal through the antenna. The transmitting process may, for example, include a power amplification process, and may further include a filtering process. Alternatively, the radio frequency module 130 can also support a receiving process on the radio frequency signal, and transmit the radio frequency signal received by the antenna to the radio frequency transceiver 110 after the receiving process. The transmitting process may, for example, include a power amplification process, a filtering process, etc., and the receiving process may, for example, include a low-noise amplification process, a filtering process, etc.

[0032] Alternatively, the radio frequency module 130 can be an integrated radio frequency device, for example, can be a FEM (Front-end Module). The FEM can be integrated with a power amplifier PA, a low-noise amplifier LNA, a switch, etc., to support functions such as power amplification, low-noise amplification, path selection switching, etc. of the radio frequency signal.

[0033] Alternatively, the number of radio frequency modules 130 in the radio frequency module 100 can be one or more. For each radio frequency module 130, transmitting process can be supported, and receiving process can also be supported. Further alternatively, each radio frequency module 130 can support a SISO (Single-Input Single-Output) transceiving scenario, and can also support a DBS (Dual Band Simultaneous) dual-transmit scenario. For multiple radio frequency modules 130, multiple radio frequency modules 130 can be combined to support MIMO (Multiple-Input Single-Output), and can also support DBS.

[0034] The radio frequency transceiver 110 can be configured with a radio frequency port to realize connection with the radio frequency module 130. The radio frequency transceiver 110 can include a transmitter to transmit a radio frequency signal to the radio frequency module 130. Alternatively, the radio frequency transceiver 110 can also include a receiver to receive a radio frequency signal processed by the radio frequency module 130, and can perform processes such as frequency mixing demodulation and decoding on the received radio frequency signal.

[0035] The voltage regulation module 120 is connected with the power supply module 200 and the radio frequency module 130 respectively, can receive the first power supply voltage from the power supply module 200, and perform voltage reduction processing on the first power supply voltage based on the determined voltage range of the first power supply voltage, to output the second power supply voltage and supply power to the radio frequency module 130. The voltage regulation module 120 performs voltage reduction processing on the first power supply voltage in the case that the radio frequency module 130 needs to perform transmission processing on the radio frequency signal to be transmitted. The obtained second power supply voltage can not only realize normal power supply to the radio frequency module 130 and ensure normal work of the radio frequency module 130, but also avoid the loss caused by unnecessary voltage boosting processing, avoid the negative income state, maximize the compression of transmission scene power consumption while ensuring the performance of the radio frequency module 130.

[0036] Generally, in the field of radio frequency, whether it is a wireless short-range system or a cellular system, the power supply voltage of the radio frequency module 130 generally follows and depends on the system voltage (corresponding to the first power supply voltage) of the power supply module 200, and cannot be dynamically adjusted. For example, when the battery voltage of the battery module 210 in the power supply module 200 is large, the power corresponds to a large amount, and the system voltage may be always higher than the typical value required by the radio frequency module 130, so that the radio frequency module 130 brings additional power consumption in the transmission process of the wireless short-range radio frequency signal, affecting the endurance of the communication device 10. For another example, when the battery voltage is small, the power corresponds to a low amount, in order to avoid that the system voltage VPH is lower than the typical value, the battery management module in the power supply module 200 usually performs voltage boosting processing on the battery voltage, and the voltage boosting processing process also brings additional power consumption, which also affects the endurance of the communication device 10.

[0037] However, the inventors have found that, for the transmission process of the radio frequency module 130 on the wireless short-range radio frequency signal, the performance of the radio frequency module 130 is almost the same under the power supply of different voltages in certain voltage range, which leads to additional power consumption.

[0038] The radio frequency module 100 provided by the embodiment includes a voltage adjustment module 120, a radio frequency module 130, and a radio frequency transceiver 110. The voltage adjustment module 120 can perform voltage reduction processing on the first power supply voltage to output a second power supply voltage to the radio frequency module 130. The second power supply voltage is determined based on a voltage range in which the first power supply voltage is located and is obtained based on voltage reduction processing on the first power supply voltage. On the one hand, the second power supply voltage can be dynamically adjusted in combination with the voltage range of the first power supply voltage to realize normal power supply of the radio frequency module 130 and ensure normal operation of the radio frequency module 130. On the other hand, unnecessary high typical values and unnecessary voltage increase processing can be avoided, and additional losses in a transmission scenario, such as the SISO, DBS, MIMO, and the like mentioned above, can be avoided, thereby avoiding a negative benefit state. Thus, the radio frequency module 100 of the embodiment can realize dynamic adjustment, maximize compression of transmission scenario power consumption, and ensure performance of the radio frequency module 130.

[0039] In one embodiment, when the first power supply voltage is greater than a preset power supply threshold, the voltage adjustment module 120 is configured to perform voltage reduction processing on the first power supply voltage to a first target voltage, and the first target voltage is less than or equal to the preset power supply threshold.

[0040] The preset power supply threshold can be understood as a relatively large corresponding first power supply voltage, that is, a relatively large system voltage and a relatively high power supply. When the first power supply voltage is greater than the preset power supply threshold, the power supply voltage of the radio frequency module 130 in the related art is usually at a relatively high typical value. However, the inventors have found that, when the voltage is different from the preset power supply threshold by a certain voltage range, the transmission performance of the radio frequency module 130 has almost no difference.

[0041] Optionally, the preset power supply threshold can be 3.5 V. A voltage greater than 3.5 V, for example, a 3.8 V voltage, corresponds to a battery power supply of about 50%, which is relatively high. Taking the WIFI FEM as an example, the corresponding relatively high typical value of the radio frequency module 130 is usually 3.85 V. As shown in FIG. 5, the performance of the FEM of a certain manufacturer under different voltages is measured. The performance of the WIFI FEM under 3.5 V and 4 V has almost no difference.

[0042] Thus, the voltage adjustment module 120 of the embodiment can reduce the first power supply voltage to be less than or equal to the preset power supply threshold when the first power supply voltage is greater than the preset power supply threshold, thereby realizing compression of transmission scenario power consumption while ensuring performance of the radio frequency module 130.

[0043] Further, in some embodiments, voltage adjustment can be realized based on a transmission scenario in which the radio frequency module 130 is specifically applied in combination with the voltage range of the first power supply voltage. For example, the following optional embodiments can be referred to:

[0044] In one of the embodiments, when the first power supply voltage is greater than the preset power supply threshold and the radio frequency module 130 is in communication connection with the connection site, the voltage regulation module 120 is configured to step down the first power supply voltage to a first voltage range; when the first power supply voltage is greater than the preset power supply threshold and the radio frequency module 130 is in communication connection with the radio frequency module 130 of the external device, the voltage regulation module 120 is configured to step down the first power supply voltage to a second voltage range; wherein the maximum value of the first voltage range is less than or equal to the preset power supply threshold, and the maximum value of the second voltage range is less than or equal to the minimum value of the first voltage range.

[0045] The first scenario in which the radio frequency module 130 is in communication connection with the connection site can be understood as a client / server communication scenario type, and the second scenario in which the radio frequency module 130 is in communication connection with the radio frequency module 130 of the external device can be understood as a client / client communication scenario type, also known as a Peer-To-Peer (P2P) scenario. The maximum value of the first voltage range being less than or equal to the preset power supply threshold can be understood as the upper limit value of the first voltage range being the preset power supply threshold, and the maximum value of the second voltage range being less than or equal to the minimum value of the first voltage range can be understood as the upper limit value of the second voltage range being equal to the lower limit value of the first voltage range.

[0046] On the one hand, the transmission power required by the radio frequency module 130 in the first scenario is greater than that in the second scenario, and on the other hand, in the second scenario, the radio frequency module 130 can act as both a sender and a receiver, and there can be a problem of easy temperature rise. In the present embodiment, when the first power supply voltage is greater than the preset power supply threshold, if the radio frequency module 130 is in the first scenario, the first power supply voltage is stepped down to the first voltage range, and if the radio frequency module 130 is in the second scenario, the first power supply voltage is stepped down to the second voltage range, and the maximum value of the first voltage range is less than or equal to the preset power supply threshold, and the maximum value of the second voltage range is less than or equal to the minimum value of the first voltage range, which can realize gradient dynamic power supply, ensure that the radio frequency module 130 can match the transmission power requirement in both scenarios, and greatly compress the power consumption while matching the transmission power requirement; in addition, it can also effectively solve the temperature rise problem in the P2P scenario.

[0047] In one of the embodiments, when the first power supply voltage is greater than the preset power supply threshold and the uplink rate of the radio frequency module 130 is lower than a preset rate threshold, the voltage regulation module 120 is configured to step down the first power supply voltage to a third voltage range; wherein the maximum value of the third voltage range is less than or equal to the minimum value of the second voltage range.

[0048] The preset rate threshold can be a low rate threshold, for example, MCS4 (16QAM). The third scenario where the uplink rate of the radio frequency module 130 is lower than the preset rate threshold can be understood as the required transmission rate of the current radio frequency module 130 being slow, and the radio frequency module 130 only needs smaller transmission power to transmit data to ensure that the data can be successfully transmitted. The maximum value of the third voltage range being less than or equal to the minimum value of the second voltage range can be understood as the upper limit value of the third voltage range being equal to the lower limit value of the second voltage range.

[0049] In the third scenario, if the first supply voltage is greater than the preset supply threshold, the voltage regulation module 120 can step down the first supply voltage to a third voltage range, and the maximum value of the third voltage range is less than or equal to the minimum value of the second voltage range, so that the second supply voltage is lower than the voltage in other scenarios, while ensuring the transmission performance of the radio frequency module 130, the power consumption is greatly compressed.

[0050] In one of the embodiments, in the case where the first supply voltage is greater than the preset supply threshold, the voltage regulation module 120 can include a boost / buck (BOB) circuit, which has a boost mode and a buck mode. In any of the above embodiments, the BOB circuit can work in the buck mode to step down the first supply voltage when the first supply voltage is greater than the preset supply threshold. The buck mode of the BOB circuit does not produce additional voltage drop during the voltage drop process, regardless of whether the battery included in the power supply module 200 is a graphite battery or a silicon negative battery, which can avoid affecting the power supply stability of the battery module 210.

[0051] In one of the embodiments, in the case where the first supply voltage is greater than the preset supply threshold, the voltage regulation module 120 includes a buck circuit for stepping down the first supply voltage to the preset supply threshold. The Buck circuit only has a buck mode, and in any of the above embodiments, the Buck circuit can start the buck mode to step down the first supply voltage when the first supply voltage is greater than the preset supply threshold. In this process, regardless of whether the battery included in the power supply module 200 is a graphite battery or a silicon negative battery, the Buck circuit does not produce additional voltage drop, which can avoid affecting the power supply stability of the battery module 210, and the structure of the Buck circuit is simpler and the cost is lower, which is conducive to reducing the cost.

[0052] It should be noted that any of the above embodiments is not limited to the specific battery type of the battery module 210 in the power supply module 200, that is, any of the above embodiments is applicable to different types of battery modules 210 in the case where the first supply voltage is greater than the preset supply threshold.

[0053] In one of the embodiments, in the case that the first supply voltage is less than the preset supply threshold, the voltage regulation module 120 is configured to step down the first supply voltage to a second target voltage, the second target voltage being less than the preset supply threshold.

[0054] In the case that the first supply voltage is less than the preset supply threshold, it can be understood that the battery voltage and the system voltage are small, and the power is low. The supply module 200 in the related art will start the Boost mode in the case that the first supply voltage is less than the preset supply threshold, and the Boost voltage will bring an additional negative yield of 1-4 mA. However, the inventors have found that in the case that the voltage is different from the preset supply threshold by a certain voltage range, the transmission performance of the radio frequency module 130 is almost the same. However, the inventors have found that for the radio frequency module 130 supporting wireless short-range mode radio frequency signals, a lower working voltage can be supported.

[0055] Optionally, in the present embodiment, the preset supply threshold can be 3.5V. Relative to the graphite battery, 3.5V corresponds to a battery power of about 10%, and less than 3.5V is close to the shutdown voltage. Taking the WIFI FEM as an example, in the case of less than 3.5V, only the performance of WIFI needs to be ensured, and the supply voltage of FEM can continue to be lowered under the condition of ensuring the basic performance of WIFI, and most FEMs can support a minimum working voltage of 2.5V, which can meet the scene demand below 3.5V.

[0056] Therefore, in order to completely eliminate this negative yield, the switching point of the Boost is dynamically adjusted. In the case that the first supply voltage is less than the preset supply threshold, the voltage regulation module 120 adopts a step-down mode to step down the first supply voltage to a second target voltage, the second target voltage being less than or equal to the preset supply threshold, so as to compress the transmission scene power consumption while ensuring the performance of the radio frequency module 130. Therefore, even in the case of power supply close to the shutdown voltage, the present embodiment can still be powered on, greatly improving the negative yield state under low power and improving the user experience.

[0057] Further, in some embodiments, the voltage regulation can be implemented based on the transmission scene of the specific application of the radio frequency module 130, in combination with the voltage range of the first supply voltage and the battery type inside each supply module 200, for example, the following optional embodiments can be referred to:

[0058] In one of the embodiments, the supply module 200 includes a power management module 220 and a battery module 210, the power management module 220 is configured to convert and process the output voltage of the battery module 210 to output a first supply voltage; the battery module 210 includes a graphite battery.

[0059] In a case that the first power supply voltage is less than the preset power supply threshold and the radio frequency module 130 is in communication connection with the connection site, the voltage regulation module 120 is configured to step down the first power supply voltage to a first voltage range; in a case that the first power supply voltage is less than the preset power supply threshold and the radio frequency module 130 is in communication connection with the radio frequency module 130 of the external device, the voltage regulation module 120 is configured to step down the first power supply voltage to a fourth voltage range; wherein a maximum value of the first voltage range is less than or equal to the preset power supply threshold, a maximum value of the fourth voltage range is less than or equal to a minimum value of the first voltage range, and a minimum value of the fourth voltage range is less than a minimum battery voltage of the graphite battery.

[0060] In the above embodiments, the scenario that the radio frequency module 130 is in communication connection with the connection site and the scenario that the radio frequency module 130 is in communication connection with the radio frequency module 130 of the external device can be referred to the above embodiments, which will not be described herein. The maximum value of the first voltage range being less than or equal to the preset power supply threshold can be understood as that an upper limit value of the first voltage range is the preset power supply threshold, and the maximum value of the fourth voltage range being less than or equal to the minimum value of the first voltage range can be understood as that an upper limit value of the fourth voltage range is equal to a lower limit value of the first voltage range. Optionally, the minimum battery voltage of the graphite battery can be 3.3V for example, and the minimum value of the fourth voltage range is less than the minimum battery voltage of the graphite battery, i.e. the minimum value of the fourth voltage range is less than 3.3V, for example, 3.0V.

[0061] On one hand, the transmission power required by the radio frequency module 130 in the first scenario is greater than that in the second scenario, and on the other hand, in the second scenario, the radio frequency module 130 can act as a sender and a receiver, and there can be a problem of easy temperature rise. In the present embodiment, in a case that the first power supply voltage is less than the preset power supply threshold, if the radio frequency module 130 is in the first scenario, the first power supply voltage is stepped down to the first voltage range, and if the radio frequency module 130 is in the second scenario, the first power supply voltage is stepped down to the fourth voltage range, and the maximum value of the first voltage range is less than or equal to the preset power supply threshold, the maximum value of the fourth voltage range is less than or equal to the minimum value of the first voltage range, and the minimum value of the fourth voltage range is less than the minimum battery voltage of the graphite battery, which can realize gradient dynamic power supply, ensure that the radio frequency module 130 can match the transmission power requirement in the two scenarios, and greatly compress power consumption while matching the transmission power requirement; in addition, it can also effectively solve the problem of temperature rise in the P2P scenario. Thus, even in the case of power supply close to the shutdown voltage, the present embodiment can still be powered on, greatly improving the negative state under low battery, and improving the user experience.

[0062] In one of the embodiments, the voltage regulation module 120 is configured to step down the first supply voltage to a fifth voltage range when the first supply voltage is less than the preset supply threshold and the uplink rate of the radio frequency module 130 is less than the preset rate threshold, wherein a maximum value of the fifth voltage range is less than a minimum value of the fourth voltage range.

[0063] The third scenario where the uplink rate is less than the preset rate threshold can refer to the above-mentioned embodiments, which will not be described herein. The maximum value of the fifth voltage range being less than the minimum value of the fourth voltage range can be understood as the upper limit value of the fifth voltage range being less than the graphite battery voltage. Optionally, the minimum battery voltage of the graphite battery can be 3.3V, and the minimum value of the fourth voltage range can be 3.0V, so that the upper limit value of the fifth voltage range can be 2.7V, which can still meet the performance requirements of WIFI FEM.

[0064] In the third scenario, if the first supply voltage is less than the preset supply threshold, the voltage regulation module 120 can step down the first supply voltage to the fifth voltage range, and the maximum value of the fifth voltage range is less than the graphite battery voltage, so that the second supply voltage is lower than the voltage in other scenarios, which can greatly compress the power consumption while ensuring the transmission performance of the radio frequency module 130, thereby further improving the space for battery life.

[0065] In one of the embodiments, the power supply module 200 includes a power management module 220 and a battery module 210, the power management module 220 is configured to convert and process the output voltage of the battery module 210 to output the first supply voltage, and the battery module 210 includes a graphite battery. In the case where the first supply voltage is less than the preset supply threshold, the voltage regulation module 120 is further configured to transmit the first supply voltage to supply power to the radio frequency module 130.

[0066] The transmission of the first supply voltage to supply power to the radio frequency module 130 can be understood as the voltage regulation module 120 having a step-down processing amplitude of 0 for the first supply voltage, so that the voltage values of the first supply voltage and the second supply voltage are equal, which is equivalent to a bypass transmission (BYPASS) state. When the battery module 210 is a graphite battery, the case where the first supply voltage is less than the preset supply threshold is close to a power-off state power, at this time, the first supply voltage is relatively small and the power consumption is low. In the case where the first supply voltage is not stepped down, on the one hand, the performance requirements of the radio frequency module 130 can be met, and on the other hand, the effect of small power consumption can also be achieved. Therefore, in the case where the first supply voltage is less than the preset supply threshold, the voltage regulation module 120 of the present embodiment transmits the first supply voltage to supply power to the radio frequency module 130, which can match the transmission power requirements while compressing the power consumption.

[0067] In one of the embodiments, the power supply module 200 comprises a power management module 220 and a battery module 210, the power management module 220 is configured to convert the output voltage of the battery module 210 to output a first power supply voltage; the battery module 210 comprises a silicon negative electrode battery; in the case that the first power supply voltage is less than a preset power supply threshold and greater than a first voltage, the voltage regulation module 120 is configured to step down the first power supply voltage to the first voltage; in the case that the first power supply voltage is less than the first voltage and greater than a second voltage, the voltage regulation module 120 is configured to step down the first power supply voltage to the second voltage; the second voltage is equal to the minimum battery voltage of the silicon negative electrode battery.

[0068] In the above embodiment, the minimum battery voltage of the silicon negative electrode battery is less than the minimum battery voltage of the graphite battery, and the battery voltage range of the silicon negative electrode battery can be 2.7V-4.5V, and the preset power supply threshold can be 3.5V, which corresponds to a battery capacity greater than 10% relative to the silicon negative electrode battery, and relative to the graphite battery, when the first power supply voltage of the power supply module 200 is less than the preset power supply threshold, the voltage regulation module 120 can further step down the first power supply voltage by a larger step-down amplitude until the first power supply voltage is stepped down to the minimum battery voltage of the silicon negative electrode battery.

[0069] Therefore, in the case that the first power supply voltage is less than the preset power supply threshold and greater than the first voltage, the voltage regulation module 120 of the present embodiment steps down the first power supply voltage to the first voltage; in the case that the first power supply voltage is less than the first voltage and greater than the second voltage, the voltage regulation module 120 steps down the first power supply voltage to the minimum battery voltage of the silicon negative electrode battery, which can greatly compress the power consumption and increase the flight endurance.

[0071] In the above embodiment, in the case that the first power supply voltage is less than the first preset voltage, the voltage regulation module 120 can greatly compress the power consumption through two gradient step-down adjustments, and in the present embodiment, the voltage regulation module 120 directly adjusts through one gradient step-down, so that the greater the input voltage and output voltage pressure difference of the voltage regulation module 120, the higher the efficiency, the greater the power consumption benefit, and the first power supply voltage is stepped down to the minimum voltage of the silicon negative electrode battery, which can further compress the power consumption in a limited amount of power to ensure the radio frequency performance and improve the endurance.

[0072] In one of the embodiments, in the case that the first supply voltage is less than the preset supply threshold, the voltage regulation module 120 can include a BOB circuit, which has a boost mode and a buck mode. In any of the above embodiments, the BOB circuit can work in the buck mode to perform buck processing on the first supply voltage in the case that the first supply voltage is less than the preset supply threshold. The buck mode of the BOB circuit does not generate additional voltage drop in the voltage drop process, regardless of whether the battery included in the power supply module 200 is a graphite battery or a silicon negative electrode battery, which can avoid affecting the power supply stability of the battery module 210.

[0073] In one of the embodiments, as shown in FIG. 6, the number of radio frequency modules 130 is multiple (4 is taken as an example in the figure), and each radio frequency module 130 is configured with a power port; the voltage regulation module 120 is connected with the power port of each radio frequency module 130 respectively to output the second supply voltage to each radio frequency module 130 respectively. Thus, based on the voltage regulation module 120 in any of the above embodiments or the combination of multiple embodiments, the overall power consumption of the radio frequency system can be greatly compressed while ensuring the radio frequency performance of each radio frequency module 130, and the endurance capability is improved.
