[0052] Please refer to Figure 1 , Figure 1 A flowchart of a communication method provided by an embodiment of the present application is shown in FIG. 1. As shown in FIG. 1, the communication method includes the following steps 101-102: Figure 1

[0053] Step 101, in the case that a communication device performs data transmission with a base station and a current temperature of the communication device is greater than a temperature threshold, a request message is sent to the base station. ​

[0054] The request message is used to request to reduce the number of uplink time slots included in a radio frame structure used by the communication device.

[0055] In the embodiments of the present application, the communication method can be applied to a communication device, which refers to a functional module or product that can implement mobile communication technology. Specifically, the communication device can include modular components such as baseband chips, radio frequency chips, memories, power amplifiers, antenna interfaces, and functional interfaces integrated on a circuit board, which can implement functions such as radio wave transmission and reception, channel noise filtering, and mutual conversion between analog signals and digital signals. For example, the communication device can be a wireless communication module, or an electronic device such as a mobile phone, a notebook, a tablet computer, etc. that includes a wireless communication module, and the present application is not limited in this regard.

[0056] As shown in Figure 2 The communication device can establish a communication connection with a base station and perform data transmission. When the communication device communicates with the base station in a time division duplexing (TDD) mode, the transmission of information in the uplink (from the communication device to the base station) and the downlink (from the base station to the communication device) can be performed on the same carrier frequency, i.e., the transmission of information in the uplink and the transmission of information in the downlink are implemented by time division on the same carrier. Further, the communication device operating in the TDD mode can use various technologies such as MIMO, HPUE, and CA, etc. to improve the data transmission rate and network coverage to obtain better network experience. For example, the communication device can increase the communication transmission distance and improve the communication effect by using higher transmission power, in which case the transmission power of the communication device on some TDD operating frequency bands can meet the new power standard Power Class 2 (3 dB higher than the existing power standard Power Class 3, which is 23 dBm). In this case, the communication device is prone to high power consumption when operating, which generates heat and reaches the operating critical temperature, affecting the communication performance and the battery life. Therefore, the communication method provided by the present application can be executed to reduce the heat generation.

[0057] In one possible implementation, the communication device can send a specific request message to the base station when the communication device is performing data transmission with the base station and the current temperature of the communication device is greater than a temperature threshold. The request message is used to request to reduce the number of uplink time slots included in a radio frame structure used by the communication device.

[0058] Specifically, the current temperature of the communication device can be obtained by a temperature detection module, which can be a temperature sensor, and the temperature detection module is arranged in the communication device. It can be understood that the temperature detection module can include one or more temperature sensors, and the plurality of temperature sensors can be distributed at different positions in the communication device, and then the current temperature of the communication device can be obtained based on the measurement results of the one or more temperature sensors. For example, the current temperature of the communication device can be obtained based on the largest measurement result of the measurement results of the one or more temperature sensors, or based on the measurement result of the temperature sensor closest to the transmission channel of the communication device. The temperature threshold described above can represent the working critical temperature of the communication device, and the temperature threshold can be a fixed value or a variable value, which can be determined according to the ambient temperature, experimental test data, etc., and the present application does not make any limitation.

[0059] It can be understood that when the communication device performs data transmission with the base station, a radio frame is used as a time unit of data transmission. The frame structure of the radio frame used by the communication device working in the TDD mode includes uplink time slots and downlink time slots, and the uplink and downlink time slot ratio in the frame structure is configurable. The radio frame structure in the Long Term Evolution (LTE) and New Radio (NR) communication system is taken as an example for introduction. Specifically, in the LTE TDD frame structure, each 10ms frame is composed of 10 1ms sub-frames, and each sub-frame includes 2 0.5ms time slots. The time slots are divided into regular time slots and special time slots, and each regular time slot has a length of 0.5ms, but every two regular time slots form a group for scheduling. The special time slots include downlink pilot time slots, guard intervals and uplink pilot time slots, and the total length is 1ms. In the frame structure, the allocation strategy of the uplink and downlink sub-frames can be set, that is, different uplink and downlink time slot ratios can be configured. The specific strategy can be as shown in the following table. Figure 3 In the NR TDD frame structure, the lengths of the radio frame and the sub-frame are fixed, and are still 10ms and 1ms respectively, but the length of the time slot can be flexibly defined according to the sub-carrier spacing (SCS), so it is different from the LTE scheduling mode according to the sub-frame. The NR takes the time slot as the basic scheduling unit, and the time slot configuration can be freely and flexibly changed. That is, as shown in the following table. Figure 4As shown, the number of uplink slots and downlink slots included in the NR TDD frame structure can be flexibly configured. Since the number of uplink slots has an impact on the power consumption and heat generation of the communication device, in this application, when the communication device generates a large amount of heat and the temperature is high, the number of uplink slots included in the frame structure used by the communication device can be reduced to reduce the power consumption of the communication device and reduce heat generation. That is, when the current temperature of the communication device is greater than the temperature threshold, the above-mentioned request message is sent to the base station to reduce the number of uplink slots included in the frame structure used by the communication device in subsequent communication, so as to reduce the power consumption and reduce the heat generation. Alternatively, when the current temperature of the communication device is equal to the temperature threshold, the above-mentioned request message can also be sent to the base station.

[0060] In a possible implementation, the operating frequency band of the transmission channel of the communication device can be determined as a time division duplex (TDD) frequency band, that is, the communication device operates in a TDD mode. The TDD frequency band can include B41 / n41 / n77 / n78 / n79, and can also include a 5G FR2 millimeter wave frequency band. Further, when the current temperature of the communication device is greater than the temperature threshold and the number of uplink slots included in the frame structure used by the communication device is greater than a first value, the above-mentioned request message is sent to the base station. The first value can be a fixed value or a value that changes according to the situation, which is not limited in this application. For example, the first value can be 1. That is, when the communication device generates a large amount of heat and reaches a high temperature, and the number of uplink slots included in the frame structure used by the communication device is large, the power consumption of the communication device can be reduced by reducing the number of uplink slots, otherwise, other methods can be used to reduce the power consumption of the communication device.

[0061] In a possible implementation, before the current temperature of the communication device reaches the temperature threshold and the communication device sends the above-mentioned request information to the base station, the communication device can receive radio resource control (RRC) signaling sent by the base station, wherein the RRC signaling includes configuration information of the frame structure used by the base station and the communication device in the data transmission process. Based on the above-mentioned RRC signaling, the frame structure used by the communication device is configured, and the frame structure used by the communication device is taken as the first frame structure. That is, the communication device determines the frame structure used in the data transmission process with the base station based on the RRC signaling sent by the base station to configure the frame structure. The frame structure corresponds to the current temperature, that is, the frame structure currently used by the communication device. The communication device can take the currently used frame structure as the first frame structure.

[0062] Step 102, receiving an acknowledgement message of the request message sent by the base station, and updating the frame structure used by the communication device based on the acknowledgement message, and performing data transmission with the base station according to the updated frame structure.

[0063] In a possible implementation, after receiving the confirmation message from the base station in response to the request message, the communication apparatus can update the frame structure used by the communication apparatus based on the confirmation message. Specifically, the communication apparatus can update the frame structure used by the communication apparatus from the first frame structure to a second frame structure based on the confirmation message. The second frame structure includes a smaller number of uplink time slots than the first frame structure. That is, the communication apparatus reduces the number of uplink time slots in the frame structure currently used by the communication apparatus based on the confirmation message to obtain the second frame structure. The second frame structure is the updated frame structure. The communication apparatus can perform data transmission with the base station according to the second frame structure. In this way, by reducing the number of uplink time slots included in the frame structure, the power consumption of the communication apparatus can be reduced, and the temperature of the communication apparatus can be reduced due to reduced heat generation.

[0064] In a possible implementation, in the process of updating the frame structure, the number of uplink time slots included in the first frame structure can be reduced by a preset number, which can be set according to an application scenario. For example, the preset number can be 1. That is, in the case that the communication apparatus generates a large amount of heat and the frame structure used by the communication apparatus includes a large number of uplink time slots, the power consumption of the communication apparatus can be reduced by gradually reducing the number of uplink time slots. Specifically, the number of uplink time slots is reduced by 1 each time, data transmission is performed with the base station based on the second frame structure, and it is checked whether the temperature of the communication apparatus is greater than the temperature threshold. If the temperature of the communication apparatus is still greater than the temperature threshold, the number of uplink time slots included in the frame structure is continuously reduced.

[0065] In a possible implementation, in a case where the number of uplink time slots included in the second frame structure is equal to the first number, data transmission can be performed between the communication device and the base station according to the second frame structure. Further, if the current temperature (i.e., real-time temperature) of the communication device is still greater than the temperature threshold, the frame structure used by the communication device can be maintained as the second frame structure, and the temperature of the communication device can be reduced by using a first temperature reduction method. The first temperature reduction method is different from the method of reducing the number of uplink time slots, and can include, but is not limited to, reducing the transmission power, reducing the transmission rate, reducing the number of carriers, and switching the uplink operating frequency band. That is, the application can preferentially reduce the power consumption of the communication device by reducing the number of uplink time slots, so as to reduce the negative impact of directly using other temperature reduction methods on the working performance and communication quality of the communication device. When the number of uplink time slots included in the frame structure used by the communication device is reduced to a lower value (i.e., the first number), the temperature reduction effect of this method reaches a limit, and if the temperature of the communication device is still greater than the temperature threshold, other methods can be used to reduce the power consumption of the communication device. It can be understood that the method for reducing the temperature of the communication device by reducing the number of uplink time slots (i.e., the temperature protection method) provided by the application can be used in combination with other temperature protection methods, so as to improve the temperature reduction effect when the communication device generates a large amount of heat, reduce the negative impact of the high temperature of the device on the data transmission rate, and improve the working performance and working time of the communication device.

[0066] In the embodiments of the application, in a case where the communication device performs data transmission with the base station and the current temperature of the communication device is greater than the temperature threshold, a request message is sent to the base station to reduce the number of uplink time slots included in the frame structure used by the communication device, and the frame structure used by the communication device is updated based on an acknowledgement message of the base station to the request message, and data transmission is performed between the communication device and the base station according to the updated frame structure. The application reduces the power consumption and heat generation by actively reducing the number of uplink time slots included in the frame structure used by the communication device, so as to achieve temperature protection and avoid the communication device from shutting down or being damaged due to the high internal temperature. This method does not affect the downlink rate and communication coverage of the communication device, and has little impact on the performance of the communication device. Further, this method can be used in combination with other temperature protection methods to improve the temperature reduction effect.

[0067] The communication method provided by the application will be described below in combination with a specific application scenario. As shown in FIG. 1, the method can include the following steps: Figure 5

[0068] (1) Determine that the current temperature of the communication device is greater than the temperature threshold, and start the temperature protection mechanism.

[0069] ​The current temperature of the communication device can be high due to a high external environment temperature or a high heat generation of the UE. The current temperature can be obtained by a temperature sensor arranged in the communication device. The temperature sensor can be arranged near a transmitting channel of the communication device, i.e., the temperature sensor can detect the temperature of an antenna and / or a power amplifier (PA).

[0070] (2) Determine whether the transmitting channel of the communication device works in a TDD frequency band. If yes, perform step (3); if no, take other temperature protection methods.

[0071] The first temperature protection method can include the first temperature reduction method described above, i.e., any one of reducing the transmitting power, reducing the transmission rate, reducing the number of carriers, and switching the uplink working frequency band.

[0072] (3) Determine whether the number of uplink time slots included in the frame structure used by the communication device is greater than a first value. If yes, perform step (4); if no, take other temperature protection methods.

[0073] For example, the first value can be 1. The frame structure currently used by the communication device can be the first frame structure.

[0074] (4) Send a request message to the base station. The request message is used to request that the number of uplink time slots included in the frame structure used by the communication device be reduced by a preset value.

[0075] For example, the preset value can be 1.

[0076] (5) Obtain an acknowledgement message sent by the base station in response to the request message, update the frame structure used by the communication device based on the acknowledgement message, and perform data transmission with the base station according to the updated frame structure.

[0077] For example, updating the frame structure used by the communication device can include updating the first frame structure to a second frame structure, and the number of uplink time slots included in the second frame structure = the number of uplink time slots included in the first frame structure - the preset value.

[0078] (5) Determine whether the current temperature of the communication device is greater than a temperature threshold. If yes, perform step (1); if no, turn off the temperature protection mechanism.

[0079] In a specific scenario, the communication device can work in a TDD mode in a 5G millimeter wave frequency band, i.e., in a FR2 frequency band (frequency range of 24 GHz to 52 GHz). Because millimeter waves are greatly attenuated during transmission, to ensure the quality of communication transmission, the communication device can be in a high-power transmission state, and thus has high power consumption and generates a lot of heat, resulting in a high temperature of the communication device. At this time, if the application is not implemented, and a method such as directly reducing the downlink rate or reducing the number of carriers is used, the problem of a high temperature near the transmission channel of the communication device, such as the temperature around the antenna, cannot be improved. If the application is implemented, when the temperature of the communication device reaches a temperature threshold, the number of uplink slots included in the frame structure used by the communication device can be gradually reduced, so as to reduce power consumption and heat generation, until the number of uplink slots does not exceed a first value. Further, when the number of uplink slots is small (the first value), the temperature of the communication device is still high, and other methods such as reducing the transmission power can be used to reduce the temperature of the communication device and reduce heat generation. The communication method provided in the application can be applied to LTE TDD, SA TDD (i.e., NR TDD), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), Global System for Mobile Communications (GSM), and the like. It can be understood that the method is better for scenarios in which the communication device works in a TDD HPUE frequency band, two or more transmission channels of the communication device work in a TDD frequency band, and the communication device works in a 5G FR2 frequency band, and can improve the cooling efficiency of the communication device.

[0080] In some possible implementation manners, the communication method provided in the application can also be applied to a time division system such as WIFI (a wireless local area network technology created based on an IEEE 802.11 standard) and Bluetooth. For example, in the Bluetooth system, the base station in the above communication method can be replaced by another communication device, that is, the Bluetooth system includes two or more communication devices that establish a communication connection. These communication devices negotiate to reduce the number of uplink slots included in the frame structure used for data transmission, so as to reduce the power consumption and heat generation of the communication device.

[0081] In some possible implementation manners, the communication method provided in the application can also be applied to a scenario of reducing radiation of a communication device. The radiation of a communication device to a human body can be measured by a specific absorption rate (SAR). In this application scenario, if the communication device works in a TDD frequency band, a similar method can be used to actively reduce the number of uplink slots and reduce the radiation damage to the human body. The method is suitable for a communication system working in a FR2 millimeter wave frequency band.
