[0051] Figure 1 A schematic diagram of a communication system applicable to an embodiment of the present application. Figure 1 The communication system shown includes a distributed unit (DU) and a radio unit (RU). A distributed unit can be connected to one or more radio units. The distributed unit communicates with the radio unit through a control plane interface and a user plane interface.

[0052] Among them, the distributed unit mainly handles services with high real-time requirements. It has the functions of the radio link control (RLC) layer, the medium access control (MAC) layer and part of the physical (PHY) layer. The distributed unit can be, for example, a baseband unit (BBU).

[0053] The RF unit is a radio unit with partial PHY layer functions. The key considerations in its design are size, weight and consumables. The RF unit may be, for example, an adaptive antenna unit (Active Antenna Unit, AAU) or a remote radio unit (Radio Remote Unit, RRU).

[0054] Figure 2 A flowchart of a method for ensuring the operational reliability of a radio frequency unit provided in an embodiment of the present application. The method comprises the following steps:

[0055] Step 201: The radio frequency unit sends the status information of the radio frequency unit to the distributed unit. Correspondingly, the distributed unit receives the status information of the radio frequency unit.

[0056] The state information of the RF unit is used to indicate the current working state of the RF unit. Exemplarily, the state information of the RF unit includes at least one of the utilization rate of the central processing unit (CPU) of the RF unit, the temperature of the RF unit, and the temperature difference information of the RF unit.

[0057] The temperature of the RF unit includes one or more of the intermediate frequency temperature of the RF unit, the RF temperature of the RF unit, or the power amplifier temperature of the RF unit. The intermediate frequency temperature refers to the internal operating temperature of the intermediate frequency module in the RF unit, the RF temperature refers to the internal operating temperature of the RF module in the RF unit, and the power amplifier temperature refers to the internal operating temperature of the power amplifier module in the RF unit.

[0058] The temperature difference information of the RF unit is used to indicate the maximum temperature difference value of the RF unit within a period of time. The maximum temperature difference value may be one or more of the maximum intermediate frequency temperature difference, the maximum RF temperature difference, and the maximum power amplifier temperature difference. The temperature difference information may be represented by the maximum temperature difference value, or by the highest temperature and the lowest temperature.

[0059] Before step 201, the RF unit also needs to obtain the state information of the RF unit. For example, the RF unit obtains the state information of the RF unit from a local device or module, such as obtaining the temperature from a temperature sensor, or the RF unit obtains the state information of the RF unit from an external monitoring unit.

[0060] Step 202: The distributed unit adjusts parameters of the radio frequency unit and / or parameters of the antenna corresponding to the radio frequency unit according to the status information of the radio frequency unit.

[0061] In a specific implementation, the distributed unit adjusts the parameters of the RF unit according to the status information of the RF unit, which may be: the distributed unit determines the parameters of the RF unit according to the status information of the RF unit, and sends the determined parameters of the RF unit to the RF unit. The distributed unit adjusts the parameters of the antenna corresponding to the RF unit according to the status information of the RF unit, which may be: the distributed unit determines the parameters of the antenna corresponding to the RF unit according to the status information of the RF unit, and sends the determined parameters of the antenna corresponding to the RF unit to the RF unit.

[0062] According to the above scheme, the distributed unit can dynamically adjust the parameters of the RF unit according to the status information of the RF unit to ensure the normal operation of the RF unit, which helps to avoid the occurrence of excessive load, excessive temperature, and excessive temperature difference, and thus will not cause data to be discarded, thereby ensuring the operational reliability of the RF unit without affecting the service quality.

[0063] As an implementation method, when the status information of the RF unit meets the preset conditions, the distributed unit is triggered to adjust the parameters of the RF unit and / or the parameters of the antenna corresponding to the RF unit according to the status information of the RF unit. The preset conditions include but are not limited to one or more of the following: the CPU usage of the RF unit is greater than the CPU usage threshold, the temperature of the RF unit is greater than the temperature threshold, and the temperature difference corresponding to the temperature difference information of the RF unit is greater than the temperature difference threshold. The CPU usage threshold, temperature threshold, and temperature difference threshold can be pre-configured on the distributed unit or sent to the distributed unit by the RF unit, which is not limited in the embodiments of the present application.

[0064] Among them, the preset condition here is determined based on the information included in the status information of the radio frequency unit. For example, the status information of the radio frequency unit received by the distributed unit includes the CPU usage rate of the radio frequency unit, and the preset condition here includes that the CPU usage rate of the radio frequency unit is greater than the CPU usage rate threshold value. For another example, the status information of the radio frequency unit received by the distributed unit includes the temperature of the radio frequency unit, and the preset condition here includes that the temperature of the radio frequency unit is greater than the temperature threshold value. For another example, the status information of the radio frequency unit received by the distributed unit includes the temperature difference information of the radio frequency unit, and the preset condition here includes that the temperature difference corresponding to the temperature difference information of the radio frequency unit is greater than the temperature difference threshold value. For another example, the status information of the radio frequency unit received by the distributed unit includes the CPU usage rate of the radio frequency unit and the temperature of the radio frequency unit, and the preset condition here includes at least one of the following: the CPU usage rate of the radio frequency unit is greater than the CPU usage rate threshold value, and the temperature of the radio frequency unit is greater than the temperature threshold value. For another example, the status information of the RF unit received by the distributed unit includes the CPU usage rate of the RF unit and the temperature difference information of the RF unit, and the preset conditions here include at least one of the following: the CPU usage rate of the RF unit is greater than the CPU usage rate threshold value, and the temperature difference corresponding to the temperature difference information of the RF unit is greater than the temperature difference threshold value. For another example, the status information of the RF unit received by the distributed unit includes the temperature of the RF unit and the temperature difference information of the RF unit, and the preset conditions here include at least one of the following: the temperature of the RF unit is greater than the temperature threshold value, and the temperature difference corresponding to the temperature difference information of the RF unit is greater than the temperature difference threshold value. For another example, the status information of the RF unit received by the distributed unit includes the CPU usage rate of the RF unit, the temperature of the RF unit, and the temperature difference information of the RF unit, and the preset conditions here include at least one of the following: the CPU usage rate of the RF unit is greater than the CPU usage rate threshold value, the temperature of the RF unit is greater than the temperature threshold value, and the temperature difference corresponding to the temperature difference information of the RF unit is greater than the temperature difference threshold value.

[0065] A method for implementing a distributed unit to adjust the parameters of a radio frequency unit, wherein the distributed unit can reduce the number of resource blocks of the radio frequency unit. For example, the distributed unit can reduce the number of resource blocks of the radio frequency unit according to a set step size or a set ratio. For another example, the distributed unit can also determine the amount of reduction of resource blocks based on the difference between the CPU utilization rate of the radio frequency unit and the CPU utilization rate threshold value, and reduce the number of resource blocks of the radio frequency unit according to the amount of reduction of resource blocks. For another example, the distributed unit can also determine the amount of reduction of resource blocks based on the difference between the temperature of the radio frequency unit and the temperature threshold value, and reduce the number of resource blocks of the radio frequency unit according to the amount of reduction of resource blocks. For another example, the distributed unit can also determine the amount of reduction of resource blocks based on the difference between the temperature difference corresponding to the temperature difference information of the radio frequency unit and the temperature difference threshold value, and reduce the number of resource blocks of the radio frequency unit according to the amount of reduction of resource blocks.

[0066] A distributed unit adjusts the parameters of a radio frequency unit, and the distributed unit can reduce the transmission power of the power amplifier module of the radio frequency unit. For example, the distributed unit can reduce the transmission power of the power amplifier module of the radio frequency unit according to a set step size or a set ratio. For another example, the distributed unit can also determine the reduction amount of the transmission power of the power amplifier module of the radio frequency unit according to the difference between the CPU usage rate of the radio frequency unit and the CPU usage rate threshold value, and reduce the transmission power of the power amplifier module of the radio frequency unit according to the reduction amount of the transmission power of the power amplifier module of the radio frequency unit. For another example, the distributed unit can also determine the reduction amount of the transmission power of the power amplifier module of the radio frequency unit according to the difference between the temperature of the radio frequency unit and the temperature threshold value, and reduce the transmission power of the power amplifier module of the radio frequency unit according to the reduction amount of the transmission power of the power amplifier module of the radio frequency unit. For another example, the distributed unit can also determine the reduction amount of the transmission power of the power amplifier module of the radio frequency unit according to the difference between the temperature difference corresponding to the temperature difference information of the radio frequency unit and the temperature difference threshold value, and reduce the amount of transmission power of the power amplifier module of the radio frequency unit according to the reduction amount of the transmission power of the power amplifier module of the radio frequency unit.

[0067] A distributed unit adjusts the parameters of a radio frequency unit. The distributed unit can adjust the weight of the antenna. The adjusted weight of the antenna is used to reduce the transmission power of the power amplifier module corresponding to the antenna. For example, the distributed unit can reduce the antenna weight according to a set step size or a set ratio. For another example, the distributed unit can also determine the reduction amount of the weight according to the difference between the CPU usage rate of the radio frequency unit and the CPU usage rate threshold value, and reduce the antenna weight according to the reduction amount of the weight. For another example, the distributed unit can also determine the reduction amount of the weight according to the difference between the temperature of the radio frequency unit and the temperature threshold value, and reduce the antenna weight according to the reduction amount of the weight. For another example, the distributed unit can also determine the reduction amount of the weight according to the difference between the temperature difference corresponding to the temperature difference information of the radio frequency unit and the temperature difference threshold value, and reduce the antenna weight according to the reduction amount of the weight. Wherein, the reduction of the antenna weight here will result in a reduction in the transmission power of the power amplifier module corresponding to the antenna in the radio frequency unit. For example, if the distributed unit reduces the weight of antenna 1, the transmission power of the power amplifier module corresponding to antenna 1 in the radio frequency unit will be reduced. For another example, reducing the weights of all antennas will result in reducing the transmit power of all power amplifier modules in the radio frequency unit.

[0068] As an implementation method, before the above step 202, the RF unit may also send indication information to the distributed unit, and the indication information indicates to adjust the parameters of the RF unit and / or the parameters of the antenna corresponding to the RF unit. The indication information will trigger the distributed unit to execute the above step 202. For example, the distributed unit is connected to 5 RF units, and the 5 RF units have sent their respective status information to the distributed unit, but 3 of the RF units have sent the indication information to the distributed unit. Then, the distributed unit may execute the above step 202 only for the 3 RF units, and may not execute the above step 202 for the other 2 RF units that have not sent the indication information. Alternatively, the distributed unit may prioritize the above multiple RF units according to whether the indication information is sent, and according to the priority ranking and its own processing capacity, execute step 202 for the above multiple RF units respectively. Through this method, the amount of calculation of the distributed unit can be reduced, which helps to reduce the load.

[0069] It should be noted that the above scheme introduces adjusting the parameters of the RF unit and / or the parameters of the antenna corresponding to the RF unit to reduce the load, temperature and / or temperature difference of the RF unit. Correspondingly, the distributed unit can also adjust the parameters of the RF unit and / or the parameters of the antenna corresponding to the RF unit when it determines that the load of the RF unit is low, the temperature is low and / or the temperature difference is small according to the state information of the RF unit to increase the load of the RF unit. Among them, the low load of the RF unit can be that the CPU usage of the RF unit is less than the first threshold value, where the first threshold value is less than or equal to the above CPU usage threshold value, the low temperature of the RF unit can be that the temperature of the RF unit is less than the second threshold value, where the second threshold value is less than or equal to the above temperature threshold value, and the temperature here can be at least one of the intermediate frequency temperature, RF temperature or power amplifier temperature of the RF unit, and the small temperature difference of the RF unit can be that the maximum temperature difference of the RF unit within a period of time is less than the third threshold value, where the third threshold value is less than or equal to the above temperature difference threshold value. Among them, adjusting the parameters of the RF unit includes increasing the amount of resources of the RF unit and / or increasing the transmission power of the power amplifier module of the RF unit, and adjusting the parameters of the antenna corresponding to the RF unit includes increasing the antenna weight to increase the transmission power of the power amplifier module corresponding to the antenna in the RF unit. Alternatively, the distributed unit may also increase the amount of resources of the RF unit and / or increase the transmission power of the power amplifier module of the RF unit by adjusting the parameters of the RF unit and / or the parameters of the antenna corresponding to the RF unit within a period of time after the execution of this step. The implementation process of increasing the load of the RF unit is the opposite process of reducing the load of the RF unit, so the specific implementation details can refer to the related description of reducing the load of the RF unit mentioned above.

[0070] Figure 3A flow chart of a method for ensuring the operational reliability of a radio frequency unit provided in an embodiment of the present application. The method comprises the following steps:

[0071] Step 301: The RF unit determines an adjustment reference value according to state information of the RF unit.

[0072] The adjustment reference value is the adjustment ratio or adjustment amount. The adjustment amount refers to the absolute value of the adjustment. Taking power as an example, an adjustment ratio of 10% means reducing the current power by 10%. An adjustment amount of 2 decibels means reducing the current power by 2 decibels.

[0073] The state information of the radio frequency unit and the method for obtaining the state information of the radio frequency unit may refer to the description of the aforementioned step 201, which will not be repeated here.

[0074] As an implementation method, when the status information of the RF unit meets the preset conditions, the RF unit determines the adjustment reference value according to the status information of the RF unit. The preset conditions include but are not limited to one or more of the following: the CPU usage of the RF unit is greater than the CPU usage threshold, the temperature of the RF unit is greater than the temperature threshold, and the temperature difference corresponding to the temperature difference information of the RF unit is greater than the temperature difference threshold. The CPU usage threshold, temperature threshold, and temperature difference threshold can be pre-configured on the RF unit or sent to the RF unit by a distributed unit, which is not limited in the embodiments of the present application.

[0075] As an implementation method, the RF unit may determine the adjustment reference value according to the difference between the CPU usage of the RF unit and the CPU usage threshold. Alternatively, the RF unit may determine the adjustment reference value according to the difference between the temperature of the RF unit and the temperature threshold. Alternatively, the RF unit may determine the adjustment reference value according to the difference between the temperature difference corresponding to the temperature difference information of the RF unit and the temperature difference threshold.

[0076] Step 302: The radio frequency unit sends an adjustment reference value to the distributed unit. Correspondingly, the distributed unit receives the adjustment reference value.

[0077] Step 303: The distributed unit adjusts the parameters of the radio frequency unit and / or the parameters of the antenna corresponding to the radio frequency unit according to the adjustment reference value.

[0078] In a specific implementation, a method for a distributed unit to adjust the parameters of a radio frequency unit according to an adjustment reference value, the distributed unit determines the parameters of the radio frequency unit according to the adjustment reference value, and sends the determined parameters of the radio frequency unit to the radio frequency unit. A method for a distributed unit to adjust the parameters of an antenna corresponding to a radio frequency unit according to an adjustment reference value, the distributed unit determines the parameters of the antenna corresponding to the radio frequency unit according to the adjustment reference value, and sends the determined parameters of the antenna corresponding to the radio frequency unit to the radio frequency unit.

[0079] According to the above scheme, the distributed unit can dynamically adjust the parameters of the RF unit according to the adjustment reference value to ensure the normal operation of the RF unit, which helps to avoid the occurrence of excessive load, excessive temperature, and excessive temperature difference, and thus will not cause data to be discarded, thereby ensuring the operational reliability of the RF unit without affecting the service quality.

[0080] A method for adjusting parameters of a radio frequency unit by a distributed unit, wherein the distributed unit reduces the number of resource blocks of the radio frequency unit according to an adjustment reference value, and / or reduces the transmission power of a power amplifier module of the radio frequency unit according to the adjustment reference value.

[0082] As an implementation method, in the above step 302, the RF unit may also send indication information to the distributed unit, and the indication information indicates to adjust the parameters of the RF unit and / or the parameters of the antenna corresponding to the RF unit. The indication information will trigger the distributed unit to perform the above step 303. Alternatively, if the RF unit does not send the indication information to the distributed unit, but only sends the above adjustment reference value, the adjustment reference value may also be used to indicate to adjust the parameters of the RF unit and / or the parameters of the antenna corresponding to the RF unit.

[0083] It should be noted that the above scheme introduces adjusting the parameters of the RF unit and / or the parameters of the antenna corresponding to the RF unit to reduce the load, temperature and / or temperature difference of the RF unit. Accordingly, when the RF unit determines that its own load is low, the temperature is low and / or the temperature difference is small, it can notify the distributed unit to adjust the parameters of the RF unit and / or the parameters of the antenna corresponding to the RF unit to increase the load of the RF unit. Among them, adjusting the parameters of the RF unit includes increasing the amount of resources of the RF unit and / or increasing the transmit power of the power amplifier module of the RF unit, and adjusting the parameters of the antenna corresponding to the RF unit includes increasing the antenna weight to increase the transmit power of the power amplifier module corresponding to the antenna in the RF unit. Alternatively, the distributed unit can also increase the amount of resources of the RF unit and / or increase the transmit power of the power amplifier module of the RF unit by adjusting the parameters of the RF unit and / or the parameters of the antenna corresponding to the RF unit within a period of time after the execution of this step. The implementation process of increasing the load of the RF unit is the opposite process of reducing the load of the RF unit, so the specific implementation details can refer to the relevant description of reducing the load of the RF unit mentioned above.
