Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method for controlling the power of a radio frequency unit, an electronic device, and a storage medium. Background Technology

[0002] In mobile communication systems, the baseband module transmits radio frequency (RF) signals to the terminal via RF units. Due to the limited coverage of RF units, a large number of RF units must be deployed to meet communication requirements. This large-scale deployment of RF units results in significant energy consumption.

[0003] In related technologies, active antennas are switched on and off to save energy. However, this method directly cuts off the communication connection between the base station and the user. When the user tries to communicate again, the communication needs cannot be met in a timely manner, affecting the user experience. Summary of the Invention

[0004] The main objective of this invention is to provide a power control method for a radio frequency unit, an electronic device, and a storage medium, which aims to reduce the power consumption of the radio frequency unit without affecting the user experience.

[0005] To achieve the above objectives, embodiments of the present invention provide a radio frequency unit power control method, comprising:

[0006] Obtain the utilization status information of each channel of the radio frequency unit;

[0007] Based on the utilization status information, the current switch state of the unit channel is adjusted to the target switch state.

[0008] To achieve the above objectives, embodiments of the present invention also propose a radio frequency unit power control method, applied to a baseband module, comprising:

[0009] Obtain the utilization status information of each channel of the radio frequency unit;

[0010] According to the status information, a control command is output to the radio frequency unit so that the radio frequency unit turns the unit channel on or off according to the control command, thereby adjusting the current on / off state of the unit channel to the target on / off state.

[0011] To achieve the above objectives, embodiments of the present invention also provide an electronic device, the electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the aforementioned method.

[0012] To achieve the above objectives, embodiments of the present invention also provide a storage medium for computer-readable storage, wherein the storage medium stores one or more programs, which can be executed by one or more processors to implement the aforementioned method.

This enables the switching state of the unit channel of the radio frequency unit to adaptively adjust with the utilization status information of the unit channel, which not only does not affect the user experience, but also achieves the effect of energy saving and power consumption reduction of the radio frequency unit.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the invention. Unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0034] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no inherent meaning. Therefore, "module," "part," or "unit" may be used interchangeably.

[0035] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0036] In mobile communication systems, such as Figure 1 As shown, base station 100 includes baseband module 110 and radio frequency unit 120. Baseband module 110 transmits radio frequency signals to terminal 200 through radio frequency unit 120. For example, in the case of explosive growth in data volume, macro base stations only carry less than 30% of the data volume. That is to say, indoor communication systems (such as active indoor distribution systems and passive indoor distribution systems) are the main bearers of data volume. Active indoor distribution systems, due to their limited coverage, have to deploy a large number of radio frequency units 120 to meet communication requirements, and large-scale deployment of radio frequency units 120 will cause huge energy consumption. Therefore, higher requirements are placed on the energy saving and consumption reduction of radio frequency units 120.

[0037] Based on the above, the present invention proposes a power control method for radio frequency units, an electronic device, and a storage medium, which can reduce the power consumption of radio frequency units without affecting the user experience.

[0038] It should be noted that the electronic device mentioned in the embodiments of the present invention can be the radio frequency unit 120, or it can be the base station 100 including the baseband module 110 and the radio frequency unit 120. Figure 1 As shown, the baseband module 110 includes a baseband processing unit 111 and a bridging device 112. The baseband processing unit 111 and the bridging device 112 are connected, and the bridging device 112 is connected to the radio frequency unit 120.

[0039] In some embodiments, the baseband module 110 includes only the baseband processing unit 111, in which case the baseband processing unit 111 is directly connected to the radio frequency unit 120.

[0040] In some embodiments, the baseband processing unit 111 is a BBU (Building Baseband Unit) distributed in the indoor distribution system.

[0041] Understandably, in practical applications, such as Figure 2 As shown, the baseband processing unit 111 can be connected to multiple bridging devices 112, and each bridging device 112 can also be connected to multiple radio frequency units 120 to enable access for more terminals 200.

[0042] The technical solution of the present invention will be described below with reference to specific embodiments.

[0043] Firstly, such as Figure 3 As shown, this embodiment of the invention provides a radio frequency (RF) unit power control method applied to an electronic device. The electronic device can be an RF unit or a base station including a baseband module and an RF unit. The method includes:

[0044] Step S110: Obtain the utilization status information of the unit channel of the radio frequency unit.

[0045] In some embodiments, the utilization status information of a unit channel of the radio frequency unit is proportional to the number of user terminal accesses; that is, the higher the number of user terminal accesses, the greater the utilization status information value of a unit channel of the radio frequency unit.

[0046] In some embodiments, step S110 is applied to a base station, which uses a baseband module to monitor the number of user terminals accessing the radio frequency unit in real time, and generates utilization status information of a unit channel of the radio frequency unit based on the number of user terminals accessing the unit. In other embodiments, step S110 is applied to the radio frequency unit, which receives the utilization status information of a unit channel of the radio frequency unit sent by the baseband module.

[0047] In some embodiments, the radio frequency unit can be an RRU (Remote Radio Unit), an AAU (Active Antenna Unit), or an AFU (Antenna Filter Unit), or other devices capable of implementing radio frequency unit functions. If the method is applied to an active or passive indoor distribution system, the radio frequency unit can be a miniature radio frequency unit, such as a miniature RRU.

[0048] Step S120: Based on the utilization status information, adjust the current switch status of the unit channel to the target switch status.

[0049] In some embodiments, as described above, the radio frequency unit receives the utilization status information of the unit channel of the radio frequency unit sent by the baseband module, and adjusts the current switch state of the unit channel of the radio frequency unit to the target switch state according to the utilization status information.

[0050] Since the utilization status information of a single channel of the radio frequency unit is generated based on the number of user terminals accessing the network, the switching status of the single channel of the radio frequency unit can be adjusted according to the utilization status information of the single channel of the radio frequency unit. This allows the switching status of the single channel of the radio frequency unit to be adaptively adjusted with the number of user terminals accessing the network, which not only does not affect the user experience, but also achieves the effect of energy saving and power consumption reduction of the radio frequency unit.

[0051] It is worth noting here that the switching state of a unit channel of the RF unit includes on or off; more specifically, it refers to the on or off state of a unit channel of the RF unit. In some embodiments, the unit channel of the RF unit is a symbol channel. The symbol channel is the time unit for carrying data and is also the smallest data scheduling unit. It can be understood that selecting the symbol channel as the unit channel to be adjusted allows for more precise and flexible power control, resulting in a higher accuracy in matching the switching state of the final adjustment target with the utilization state information of the unit channel.

[0052] Understandably, the unit channel of a radio frequency (RF) unit can also be a slot channel or a frame channel. In the field of communications, a time period is set when processing data. Assuming a period of 10ms, 10ms is divided into 20 slot channels, namely slot channel 0 to slot channel 19. Each slot channel is further divided into 14 symbol channels (such as OFDM symbols, where one symbol channel corresponds to one time-domain resource location), namely symbol channel 0 to symbol channel 13.

[0053] In some embodiments, such as Figure 4 As shown, step S120 includes the following steps:

[0054] Step S121: Based on the utilization status information, turn the power amplifier corresponding to the unit channel on or off, so that the current switch state of the unit channel is adjusted to the target switch state.

[0055] In some embodiments, the RF unit adjusts the switching state of a unit channel by turning the power amplifier corresponding to that channel on or off. It is understood that a power amplifier is a power amplifier; turning on the power amplifier means powering it on, and turning it off means powering it off.

[0056] It should be noted that when the power amplifier corresponding to a unit channel is turned on, the corresponding unit channel is turned on; when the power amplifier corresponding to a unit channel is turned off, the corresponding unit channel is turned off.

[0057] In some embodiments, such as Figure 5 As shown, step S120 includes the following steps:

[0058] Step S122: Based on the utilization status information, turn the data of the unit channel on or off so that the current switch state of the unit channel is adjusted to the target switch state.

[0059] In some embodiments, based on the utilization status information, the unit channel is enabled to transmit data normally, and the unit channel is turned on. Similarly, based on the utilization status information, the unit channel is disabled to transmit data, and the unit channel is turned off. By enabling or disabling the unit channel's data, the current on / off state of the unit channel is adjusted to the target on / off state. In some embodiments, the data of the unit channel is the IQ data (in-phase / quadrature data) carried by the unit channel.

[0060] In some embodiments, such as Figure 6 As shown, step S120 includes the following steps:

[0061] Step S123: Based on the utilization status information, turn the data of the unit channel on or off;

[0062] Step S124: Detect the power of the unit channel;

[0063] Step S125: Based on the detection results, turn the power amplifier corresponding to the unit channel on or off, so that the current switch state of the unit channel is adjusted to the target switch state.

[0064] In some embodiments, the power of a unit channel is detected by turning the data on or off based on the utilization status information. In conjunction with the above, if the unit channel is a symbol channel, then the power of the unit channel is the power of the IQ data (in-phase / quadrature data) carried by the symbol channel. For example, if the symbol channel carries 30 bits of IQ data, m bits of in-phase data, and n bits of quadrature data, m+n=30, then the power of the unit channel is m^2+n^2. The RF unit turns the power amplifier corresponding to the unit channel on or off based on the detected power. Specifically, if the detected power m^2+n^2 of the unit channel is 0, the power amplifier corresponding to the unit channel is turned off; if the detected power m^2+n^2 of the unit channel is normal, the power amplifier corresponding to the unit channel is turned on, so that the current switching state of the unit channel is adjusted to the target switching state.

[0065] In summary, adjusting the current on / off state of a unit channel to the target on / off state can be achieved in three ways: (1) turning the power amplifier corresponding to the unit channel on or off; (2) turning the data of the unit channel on or off; (3) turning the data of the unit channel on or off, detecting the power of the unit channel, and turning the power amplifier corresponding to the unit channel on or off based on the detection result. In practical applications, the appropriate method can be selected based on the specific circumstances.

[0066] In some embodiments, status information is used to classify according to levels. When the status information used is level N, N is a positive integer greater than or equal to 1, correspondingly, as... Figure 7 As shown, step S120 includes:

[0067] Step S123: Based on the Nth level utilization status information and the preset channel control rules, adjust the current switch state of the unit channel to the switch state of the target corresponding to the Nth level utilization status information.

[0068] In some embodiments, to better adapt the switching state of a unit channel of the radio frequency unit to the number of user terminal accesses, multiple levels of utilization status information can be set. Each level of utilization status information corresponds to a different number of user terminal accesses. That is, as the number of user terminal accesses gradually decreases, some unit channels can be gradually shut down in a step-like manner, which is flexible and energy-saving without affecting the user experience. When the utilization status information is at level N, the radio frequency unit adjusts the current switching state of the unit channel of the radio frequency unit to the target switching state corresponding to the level N utilization status information according to the level N utilization status information and the preset channel control rules.

[0069] In some embodiments, the preset channel control rules include:

[0070] Level N utilizes the mapping relationship between state information and the target's on / off state.

[0071] In some embodiments, state information is used to classify according to levels, and each level uses state information to map the on / off state of a target. It is worth noting here that the on / off state of the target refers to which unit channels of the radio frequency unit are on and which unit channels are off, or how many unit channels are on and how many unit channels are off.

[0072] Using state information utilization as a categorized system, divided into four levels (including Level 1, Level 2, Level 3, and Level 4 state information utilization), and taking a symbol channel as the unit channel, with a total of 14 symbol channels, as an example, the following explanation is provided:

[0073] If the target's switch state is fully open according to the first level of state information mapping, then all symbol channels will be turned on according to the first level of state information.

[0074] The second level utilizes the target's on / off state mapped by state information. The first case is state A (2 symbol channels off, 12 symbol channels on). Based on the second level's state information, the current on / off state of the symbol channels is adjusted to 2 symbol channels off and 12 symbol channels on. Symbol channels can be randomly selected to be on or off, as long as the adjustment is to 2 symbol channels off and 12 symbol channels on. It is understood that, preferably, if 5 symbol channels are currently off and 9 are on, then 3 are randomly selected from the 5 off symbol channels to be on, improving efficiency. The second case is state B (symbol channels 0 and 1 off, symbol channels 2 through 13 on). Based on the second level's state information, the current on / off state of the symbol channels is adjusted to symbol channels 0 and 1 off, and symbol channels 2 through 13 on.

[0075] The third level utilizes the target's switch state mapped from state information, which is similar to the second level's use of state information.

[0076] If the target's switch state, mapped by the fourth level using state information, is that all symbol channels are off, then according to the fourth level's use of state information, all symbol channels will be turned off.

[0077] For further examples, please refer to Application Examples 3 through 7 below.

[0078] In some embodiments, such as Figure 8 As shown, step S110 includes:

[0079] Step S111: Generate utilization status information based on the utilization rate of the unit channel of the radio frequency unit.

[0080] In some embodiments, step S111 is applied to a base station, which uses a baseband module to monitor the number of user terminals accessing the radio frequency unit in real time, converts it into the utilization rate of a unit channel of the radio frequency unit (the utilization rate of a unit channel is the ratio of the number of units used to the total number of units), generates utilization status information based on the utilization rate of a unit channel of the radio frequency unit, and sends it to the radio frequency unit.

[0081] In some embodiments, the baseband module can be used to directly generate utilization status information based on the number of user terminal accesses, or the baseband module can be used to convert the number of user terminal accesses into the number of utilizations per unit channel of the radio frequency unit, and utilization status information can be generated based on the number of utilizations per unit channel of the radio frequency unit.

[0082] In some embodiments, the baseband module includes a baseband processing unit and a bridging device. The baseband processing unit is connected to the radio frequency (RF) unit via the bridging device. The baseband processing unit monitors the number of user terminal accesses to the RF unit in real time, converts this into the utilization rate of a single channel of the RF unit, generates utilization status information based on the utilization rate of the single channel of the RF unit, and sends the utilization status information to the bridging device. The bridging device then enables or disables the data of the corresponding single channel of the RF unit based on the utilization status information. The process of enabling or disabling the data of the corresponding single channel is described in the description of step S122 and will not be repeated here.

[0083] The radio frequency unit power control method described in the first aspect will be explained in detail below through two specific application examples.

[0084] Application Example 1

[0085] The RF unit power control method described in the first aspect is applied to the RF unit. The RF unit receives the utilization status information of the unit channel from the baseband module. The RF unit parses the utilization status information, and according to the utilization status information, turns on or off the data of the corresponding unit channel, detects the power of the corresponding unit channel, and if the power is normal, turns on the power amplifier corresponding to the unit channel; if the power is 0, turns off the power amplifier corresponding to the unit channel, thereby turning on or off the corresponding unit channel to adjust the current switching state of the unit channel to the target switching state.

[0086] Application Example 2

[0087] The radio frequency unit power control method described in the first aspect is applied to a base station including a baseband module and a radio frequency unit.

[0088] If the baseband module includes a baseband processing unit and a bridging device, and the baseband processing unit and the radio frequency (RF) unit are connected via the bridging device, the baseband processing unit monitors the number of user terminal accesses to the RF unit in real time, converts this into the utilization rate of each RF unit channel, generates utilization status information based on the utilization rate of each RF unit channel, and sends this information to the bridging device. The bridging device parses the utilization status information and, based on this information, enables or disables the data of the corresponding RF unit channel. The RF unit detects the power of all channel units, enables the power amplifier corresponding to the channel with normal power, and disables the power amplifier corresponding to the channel with zero power, thereby enabling or disabling the corresponding channel to adjust its current switching state to the target switching state.

[0089] If the baseband module only includes a baseband processing unit and not a bridging device (i.e., the baseband processing unit is directly connected to the radio frequency (RF) unit), then the baseband processing unit monitors the number of user terminals accessing the RF unit in real time, converts this into the utilization rate of each RF unit channel, generates utilization status information based on the utilization rate of each RF unit channel, and sends this utilization status information to the RF unit. The RF unit receives the utilization status information of each RF unit channel sent by the baseband processing unit. The subsequent steps executed by the RF unit are described in Application Example 1 and will not be repeated here.

[0090] Secondly, such as Figure 9 As shown, this embodiment of the invention provides a radio frequency unit power control method applied to a baseband module. The method includes:

[0091] Step S210: Obtain the utilization status information of the unit channel of the radio frequency unit.

[0092] In some embodiments, the baseband module monitors the number of user terminals accessing the radio frequency unit in real time and generates utilization status information of each channel of the radio frequency unit based on the number of user terminals accessing the unit.

[0093] Step S220: Output control commands to the radio frequency unit according to the status information, so that the radio frequency unit turns the unit channel on or off according to the control commands, thereby adjusting the current switch state of the unit channel to the target switch state.

[0094] In some embodiments, the baseband module outputs control commands to the radio frequency unit based on the utilization status information. The radio frequency unit turns the unit channel on or off according to the control commands, thereby adjusting the current switching state of the unit channel to the target switching state.

[0095] In some embodiments, the control command may include identification information of the unit channel (e.g., the name and location of the unit channel) generated by the baseband module based on the parsing of the status information, and may also include information on turning the unit channel on or off. Correspondingly, the radio frequency unit turns the corresponding unit channel on or off based on the identification information of the unit channel, or the radio frequency unit turns the corresponding unit channel on or off based on the information on turning the unit channel on or off.

[0096] Since the utilization status information of a single channel of the radio frequency unit is generated based on the number of user terminals accessing the network, the switching status of the single channel of the radio frequency unit can be adjusted according to the utilization status information of the single channel of the radio frequency unit. This allows the switching status of the single channel of the radio frequency unit to be adaptively adjusted with the number of user terminals accessing the network, which not only does not affect the user experience, but also achieves the effect of energy saving and power consumption reduction of the radio frequency unit.

[0097] In some embodiments, such as Figure 10 As shown, step S220 includes:

[0098] Step S221: Based on the utilization status information, turn the data of the unit channel on or off.

[0099] In some embodiments, the baseband module enables data transmission on a unit channel of the radio frequency unit based on the utilization status information of that unit channel, meaning the unit channel of the radio frequency unit transmits data normally. Similarly, the baseband module disables data transmission on a unit channel of the radio frequency unit based on the utilization status information of that unit channel, meaning the unit channel of the radio frequency unit does not transmit data.

[0100] Step S222: Output the data of the unit channel to the radio frequency unit so that the radio frequency unit can detect the power of the data of the unit channel and turn the unit channel on or off according to the control command, thereby adjusting the current switching state of the unit channel to the target switching state.

[0101] In some embodiments, after the baseband module turns the data of a unit channel on or off, it outputs the data of the unit channel to the radio frequency unit (if the data of the unit channel is turned off, it is equivalent to the data output to the radio frequency unit being 0 bits). The radio frequency unit detects the power of the received data of the unit channel. If the power is normal, it turns on the corresponding unit channel according to the control command; if the power is 0, it turns off the corresponding unit channel according to the control command, thereby adjusting the current switching state of the unit channel to the target switching state.

[0102] In some embodiments, such as Figure 11 As shown, step S210 includes:

[0103] Step S211: Generate utilization status information based on the utilization rate of the unit channel of the radio frequency unit.

[0104] In some embodiments, the baseband module monitors the number of user terminals accessing the radio frequency unit in real time, converts it into the utilization rate of the radio frequency unit's unit channel (the utilization rate of the unit channel is the ratio of the number of utilized unit channels to the total number of unit channels), generates utilization status information based on the utilization rate of the radio frequency unit's unit channel, and sends it to the radio frequency unit.

[0105] In some embodiments, the baseband module may also directly generate utilization status information based on the number of user terminal accesses, or convert the number of user terminal accesses into the number of utilizations per unit channel of the radio frequency unit, and generate utilization status information based on the number of utilizations per unit channel of the radio frequency unit.

[0106] In some embodiments, the baseband module includes a baseband processing unit and a bridging device. The baseband processing unit is connected to the radio frequency (RF) unit via the bridging device. The baseband processing unit monitors the number of user terminal accesses to the RF unit in real time, converts this into the utilization rate of a single channel of the RF unit, generates utilization status information based on the utilization rate of the single channel, and sends the utilization status information to the bridging device. The bridging device then enables or disables the data of the corresponding single channel based on the utilization status information. The process of enabling or disabling the data of the corresponding single channel is described in the description of step S221 and will not be repeated here.

[0107] The following five specific application examples illustrate the RF unit power control method. In all five examples, a single channel is used as the symbol channel. First, the following definitions are made:

[0108] The state information is divided into four levels: the first level using state information t, the second level using state information x, the third level using state information y, and the fourth level using state information z.

[0109] Correspondingly, the utilization rate of the symbol channel also has four threshold ranges: >75%, 50%–75%, 25%–50%, and <25%.

[0110] Correspondingly, the radio frequency unit also has four operating states, namely:

[0111] Normal operating condition: Symbol channel utilization > 75%, corresponding to the first level utilization status information t;

[0112] Level 1 energy saving status: The utilization rate of the symbol channel is between 50% and 75%, and the corresponding utilization status information is Level 2 utilization status information x;

[0113] Level 2 energy saving status: The utilization rate of the symbol channel is between 25% and 50%, and the corresponding utilization status information is Level 3 utilization status information y;

[0114] Level 3 energy saving status: The utilization rate of the symbol channel is <25%, and the corresponding utilization status information is Level 4 utilization status information z.

[0115] Application Example 3

[0116] In application example three, such as Figure 1 As shown, the baseband module 110 includes a baseband processing unit 111 and a bridging device 112, which is connected to a radio frequency unit 120.

[0117] like Figure 12 As shown, the baseband processing unit 111 detects that the utilization rate of the symbol channel of the radio frequency unit 120 is between 50% and 75%, generates second-level utilization status information x, and transmits it down to the bridging device 112. The bridging device 112 receives the second-level utilization status information x and shuts down the data of symbol channel 0 and symbol channel 1 of the radio frequency unit 120. The radio frequency unit 120 calculates the power of symbol channel 0 and symbol channel 1. If the power is 0, it shuts down the power amplifiers corresponding to symbol channel 0 and symbol channel 1, and the radio frequency unit 120 enters a first-level power-saving state.

[0118] When the number of user terminals accessing the RF unit 120 increases, the baseband processing unit 111 detects that the utilization rate of the symbol channel of the RF unit 120 is >75%, generates first-level utilization status information t, and transmits it down to the bridging device 112. The bridging device 112 receives the first-level utilization status information t, enables data in symbol channel 0 and symbol channel 1 of the RF unit 120; the RF unit 120 calculates the power of symbol channel 0 and symbol channel 1, and if the power is normal, turns on the power amplifiers corresponding to symbol channel 0 and symbol channel 1, and the RF unit 120 enters normal operation from the first-level energy-saving state.

[0119] Application Example 4

[0120] In application example four, such as Figure 1 As shown, the baseband module 110 includes a baseband processing unit 111 and a bridging device 112, which is connected to a radio frequency unit 120.

[0121] like Figure 13 As shown, the baseband processing unit 111 detects that the utilization rate of the symbol channel of the radio frequency unit 120 is between 50% and 75%, generates second-level utilization status information x, and transmits it down to the bridging device 112. Upon receiving the second-level utilization status information x, the bridging device 112 shuts down the data of symbol channel 0 and symbol channel 1 of the radio frequency unit 120. The radio frequency unit 120 calculates the power of symbol channel 0 and symbol channel 1. If the power is 0, it shuts down the power amplifiers corresponding to symbol channel 0 and symbol channel 1, and the radio frequency unit 120 enters a first-level power-saving state.

[0122] When the number of user terminal accesses to the RF unit 120 decreases, the baseband processing unit 111 detects that the utilization rate of the symbol channels of the RF unit 120 is between 25% and 50%, generates third-level utilization status information y, and transmits it down to the bridging device 112. Upon receiving the third-level utilization status information y, the bridging device 112 shuts down the data of symbol channels 0, 1, 6, and 7 of the RF unit 120. The RF unit 120 calculates the power of symbol channels 0, 1, 6, and 7. If the power is 0, it shuts down the power amplifiers corresponding to symbol channels 0, 1, 6, and 7, and the RF unit 120 transitions from a first-level energy-saving state to a second-level energy-saving state.

[0123] Application Example 5

[0124] In application example five, such as Figure 1 As shown, the baseband module 110 includes a baseband processing unit 111 and a bridging device 112, which is connected to a radio frequency unit 120.

[0125] like Figure 14 As shown, the baseband processing unit 111 detects that the utilization rate of the symbol channel of the radio frequency unit 120 is between 50% and 75%, generates second-level utilization status information x, and transmits it down to the bridging device 112. Upon receiving the second-level utilization status information x, the bridging device 112 shuts down the data of symbol channel 0 and symbol channel 1 of the radio frequency unit 120. The radio frequency unit 120 calculates the power of symbol channel 0 and symbol channel 1. If the power is 0, it shuts down the power amplifiers corresponding to symbol channel 0 and symbol channel 1, and the radio frequency unit 120 enters a first-level power-saving state.

[0126] When the number of user terminal accesses to the RF unit 120 decreases, the baseband processing unit 111 detects that the utilization rate of the symbol channels of the RF unit 120 is between 25% and 50%, generates third-level utilization status information y, and transmits it down to the bridging device 112. Upon receiving the third-level utilization status information y, the bridging device 112 shuts down the data of symbol channels 0, 1, 6, and 7 of the RF unit 120. The RF unit 120 calculates the power of symbol channels 0, 1, 6, and 7. If the power is 0, it shuts down the power amplifiers corresponding to symbol channels 0, 1, 6, and 7, and the RF unit 120 transitions from a first-level energy-saving state to a second-level energy-saving state.

[0127] When the number of user terminal accesses to the RF unit 120 continues to decrease, the baseband processing unit 111 detects that the utilization rate of the symbol channels of the RF unit 120 is <25%, generates fourth-level utilization status information z, and transmits it down to the bridging device 112. Upon receiving the fourth-level utilization status information z, the bridging device 112 shuts down the data of symbol channels 0, 1, 6, 7, 10, and 11 of the RF unit 120. The RF unit 120 calculates the power of symbol channels 0, 1, 6, 7, 10, and 11. If the power is 0, the power amplifiers corresponding to symbol channels 0, 1, 6, 7, 10, and 11 are turned off, and the RF unit 120 transitions from a second-level energy-saving state to a third-level energy-saving state.

[0128] Application Example Six

[0129] In application example six, such as Figure 1 As shown, the baseband module 110 includes a baseband processing unit 111 and a bridging device 112, which is connected to a radio frequency unit 120.

[0130] like Figure 15 As shown, the baseband processing unit 111 detects that the utilization rate of the symbol channel of the radio frequency unit 120 is between 50% and 75%, generates second-level utilization status information x, and transmits it down to the bridging device 112. Upon receiving the second-level utilization status information x, the bridging device 112 shuts down the data of symbol channel 0 and symbol channel 1 of the radio frequency unit 120. The radio frequency unit 120 calculates the power of symbol channel 0 and symbol channel 1. If the power is 0, it shuts down the power amplifiers corresponding to symbol channel 0 and symbol channel 1, and the radio frequency unit 120 enters a first-level power-saving state.

[0131] When the number of user terminals accessing the RF unit 120 decreases significantly, for example, if one RF unit 120 can only cover the user terminals in one room, and all the user terminals in that room leave together, the number of user terminals accessing the RF unit 120 experiences a large jump, causing the symbol channel utilization rate to drop from 50%–75% to <25%. The baseband processing unit 111 detects that the symbol channel utilization rate of the RF unit 120 is <25%, generates fourth-level utilization status information z, and transmits it down to the bridging device 112. Upon receiving the fourth-level utilization status information z, the bridging device 112 shuts down the data in symbol channels 0, 1, 6, 7, 10, and 11 of the RF unit 120. The RF unit 120 calculates the power of symbol channels 0, 1, 6, 7, 10, and 11. If the power is 0, the corresponding power amplifiers for symbol channels 0, 1, 6, 7, 10, and 11 are turned off, and the RF unit 120 transitions from a first-level energy-saving state to a third-level energy-saving state.

[0132] Application Example 7

[0133] In application example seven, such as Figure 16 As shown, the baseband module 110 includes a baseband processing unit 111 and a bridging device 112. The bridging device 112 connects two radio frequency units, namely a first radio frequency subunit 121 and a second radio frequency subunit 122.

[0134] like Figure 17 As shown, the baseband processing unit 111 monitors that the utilization rate of the symbol channel of the first RF subunit 121 is between 25% and 50%, and the utilization rate of the symbol channel of the second RF subunit 122 is >75%. It generates third-level utilization status information y and first-level utilization status information t, and transmits them down to the bridging device 112. The bridging device 112 receives the third-level utilization status information y and the first-level utilization status information t, and shuts down the data of symbol channels 0, 1, 6, and 7 of the first RF subunit 121. The second RF subunit 122 transmits data normally. The first RF subunit 121 calculates the power of symbol channels 0, 1, 6, and 7. If the power is 0, it shuts down the power amplifiers corresponding to symbol channels 0, 1, 6, and 7. The symbol channels of the second RF subunit 122 are fully open, and the corresponding power amplifiers are also fully open. The first RF subunit 121 enters a second-level power-saving state, and the second RF subunit 122 is in normal operating condition.

[0135] When a user terminal within the coverage area of ​​the second RF subunit 122 moves to the coverage area of ​​the first RF subunit 121, the baseband processing unit 111 detects that the utilization rate of the symbol channel of the first RF subunit 121 has increased to 50%–75%, and detects that the utilization rate of the symbol channel of the second RF subunit 122 has decreased to 50%–75%. It generates second-level utilization status information x1 and second-level utilization status information x2, and transmits them down to the bridging device 112. The bridging device 112 receives the second-level utilization status information x1 and enables data in symbol channels 6 and 7 of the first RF subunit 121; it receives the second-level utilization status information x2 and disables data in symbol channels 0 and 1 of the second RF subunit 122. The first RF subunit 121 calculates the power of symbol channels 6 and 7. If the power is normal, it turns on the power amplifiers corresponding to symbol channels 6 and 7. The second RF subunit 122 calculates the power of symbol channels 0 and 1. If the power is 0, it turns off the power amplifiers corresponding to symbol channels 0 and 1. The first radio frequency subunit 121 transitions from the second-level energy-saving state to the first-level energy-saving state, and the second radio frequency subunit 122 transitions from the normal operating state to the first-level energy-saving state.
