Description

Communication method, communication device and communication system Technical Field

[0001] The embodiments of the present application relate to the field of wireless communication technologies, and in particular, to a communication method, a communication device, and a communication system. Background Art

[0002] When a device sends data, the maximum transmit power of the device cannot be exceeded. That is, the sum of the transmit powers of each unit resource carrying data cannot exceed the maximum transmit power of the device.

[0003] In order to fully utilize the transmission power of the device, during actual transmission, data is generally sent at a power close to the maximum transmission power of the device.

[0004] Therefore, how to improve the utilization rate of the device's transmission power is an important issue.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide a communication method, a communication device, and a communication system for improving the utilization rate of the transmission power of a device.

[0007] In a first aspect, embodiments of the present application provide a communication method that can be performed by a second device or a module (e.g., a chip) in the second device. The method includes: sending first data to the first device based on a first power aggregation capability of the first device; receiving feedback information from the first device; and sending second data to the first device based on a second power aggregation capability of the first device, where the second power aggregation capability is determined based on the feedback information and the first power aggregation capability.

[0008] The above scheme dynamically adjusts the power aggregation capability of the first device according to the feedback information of the first device, can reasonably determine the power aggregation capability of the first device, and helps to improve the utilization rate of the transmission power of the first device while ensuring the normal operation of the first device.

[0009] In a possible implementation method, the first power aggregation capability is received from the first device, where the first power aggregation capability is an initial power aggregation capability of the first device.

[0010] In the above solution, the first device reports its own initial power aggregation capability, which helps the second device determine a more appropriate power aggregation capability for the first device based on the initial power aggregation capability.

[0011] In a possible implementation method, the first power aggregation capability is a default initial power aggregation capability of the first device.

[0012] In the above solution, the initial power aggregation capability of the first device is default, so the first device does not need to report the initial power aggregation capability to the second device, which helps to save signaling overhead.

[0013] In one possible implementation method, the feedback information includes at least one of the following information:

[0014] Status information of the first device, the status information being used to indicate a working status of the first device, the working status being normal or alarm;

[0015] indicator information of the first device, the indicator information comprising at least one of a crest factor reduction (CFR) dropout rate, a digital predistortion (DPD) convergence state, or an error vector magnitude (EVM) value;

[0016] Indication information, where the indication information is used to instruct to increase or decrease the power aggregation capability of the first device.

[0017] In the above solution, the first device accurately reports the working status of the first device to the second device through feedback information, so that the second device can accurately determine the adjustment method for the power convergence capability of the first device based on the feedback information, which helps to determine the appropriate power convergence capability.

[0018] In one possible implementation method, when the feedback information includes the status information and the status information indicates that the working status of the first device is normal, the maximum transmit power on the unit resource corresponding to the second power convergence capability is greater than or equal to the maximum transmit power on the unit resource corresponding to the first power convergence capability; or, when the feedback information includes the status information and the status information indicates that the working status of the first device is an alarm, the maximum transmit power on the unit resource corresponding to the second power convergence capability is less than or equal to the maximum transmit power on the unit resource corresponding to the first power convergence capability.

[0019] In one possible implementation method, when the feedback information includes the indicator information and the indicator information satisfies a first condition, the maximum transmit power per unit resource corresponding to the second power convergence capability is greater than or equal to the maximum transmit power per unit resource corresponding to the first power convergence capability; or, when the feedback information includes the indicator information and the indicator information does not satisfy the first condition, the maximum transmit power per unit resource corresponding to the second power convergence capability is less than or equal to the maximum transmit power per unit resource corresponding to the first power convergence capability; wherein the first condition includes at least one of the following: the CFR leakage rate is lower than the leakage rate threshold, the DPD convergence state is convergence, and the EVM value is less than the EVM threshold.

[0020] In one possible implementation method, when the feedback information includes the indication information and the indication information indicates to increase the power convergence capability of the first device, the maximum transmit power on the unit resource corresponding to the second power convergence capability is greater than or equal to the maximum transmit power on the unit resource corresponding to the first power convergence capability; or, when the feedback information includes the indication information and the indication information indicates to decrease the power convergence capability of the first device, the maximum transmit power on the unit resource corresponding to the second power convergence capability is less than or equal to the maximum transmit power on the unit resource corresponding to the first power convergence capability.

[0021] In a possible implementation method, when both the first data and the second data are data of a first service, a correspondence between the second power aggregation capability and the characteristic information is established according to characteristic information of the first service.

[0022] In the above scheme, after the second device establishes a correspondence between the second power aggregation capability and the characteristic information of the first service, when the second device subsequently sends data for the first service, it obtains the corresponding power aggregation capability of the first device (i.e., the second power aggregation capability) based on the characteristic information of the first service, and then uses the second power aggregation capability to send data for the first service, without the need to dynamically adjust the power aggregation capability of the first device. In this way, the power consumption and resource overhead caused by dynamic adjustment of the first and second devices can be reduced, and the service life of the first device can be avoided from being shortened or even damaged due to frequent alarms caused by dynamic adjustment.

[0023] In a possible implementation method, the characteristic information of the first service includes one or more of the following: distribution characteristics of data of the first service in the frequency domain, and power distribution corresponding to the data of the first service.

[0024] In a possible implementation method, the feedback information is received based on a periodic reception or based on event triggering.

[0025] In a second aspect, embodiments of the present application provide a communication method that can be performed by a first device or a module (such as a chip) in the first device. The method includes: receiving first data from a second device, the first data corresponding to a first power aggregation capability of the first device; and sending feedback information to the second device, the feedback information being used to reflect the operating status of the first device when the power aggregation capability of the first device is the first power aggregation capability.

[0026] The above scheme dynamically adjusts the power aggregation capability of the first device according to the feedback information of the first device, can reasonably determine the power aggregation capability of the first device, and helps to improve the utilization rate of the transmission power of the first device while ensuring the normal operation of the first device.

[0027] In a possible implementation method, the first power aggregation capability is sent to the second device, where the first power aggregation capability is the initial power aggregation capability of the first device.

[0028] In the above solution, the first device reports its own initial power aggregation capability, which helps the second device determine a more appropriate power aggregation capability for the first device based on the initial power aggregation capability.

[0029] In a possible implementation method, the first power aggregation capability is a default initial power aggregation capability of the first device.

[0030] In the above solution, the initial power aggregation capability of the first device is default, so the first device does not need to report the initial power aggregation capability to the second device, which helps to save signaling overhead.

[0031] In a possible implementation method, second data is received from the second device, where the second data corresponds to a second power convergence capability of the first device, and the second power convergence capability is determined based on the feedback information and the first power convergence capability.

[0032] In one possible implementation method, the feedback information includes at least one of the following information:

[0033] status information of the first device, the status information being used to indicate a working status of the first device;

[0034] Index information of the first device, the index information comprising at least one of a CFR leakage rate, a DPD convergence state, or an EVM value;

[0035] Indication information, where the indication information is used to instruct to increase or decrease the power aggregation capability of the first device.

[0036] In the above solution, the first device accurately reports the working status of the first device to the second device through feedback information, so that the second device can accurately determine the adjustment method for the power convergence capability of the first device based on the feedback information, which helps to determine the appropriate power convergence capability.

[0037] In one possible implementation method, when the feedback information includes the status information and the status information indicates that the working status of the first device is normal, the maximum transmit power on the unit resource corresponding to the second power convergence capability is greater than or equal to the maximum transmit power on the unit resource corresponding to the first power convergence capability; or, when the feedback information includes the status information and the status information indicates that the working status of the first device is an alarm, the maximum transmit power on the unit resource corresponding to the second power convergence capability is less than or equal to the maximum transmit power on the unit resource corresponding to the first power convergence capability.

[0038] In one possible implementation method, when the feedback information includes the indicator information and the indicator information satisfies a first condition, the maximum transmit power per unit resource corresponding to the second power convergence capability is greater than or equal to the maximum transmit power per unit resource corresponding to the first power convergence capability; or, when the feedback information includes the indicator information and the indicator information does not satisfy the first condition, the maximum transmit power per unit resource corresponding to the second power convergence capability is less than or equal to the maximum transmit power per unit resource corresponding to the first power convergence capability; wherein the first condition includes at least one of the following: the CFR leakage rate is lower than the leakage rate threshold, the DPD convergence state is convergence, and the EVM value is less than the EVM threshold.

[0039] In one possible implementation method, when the feedback information includes the indication information and the indication information indicates to increase the power convergence capability of the first device, the maximum transmit power on the unit resource corresponding to the second power convergence capability is greater than or equal to the maximum transmit power on the unit resource corresponding to the first power convergence capability; or, when the feedback information includes the indication information and the indication information indicates to decrease the power convergence capability of the first device, the maximum transmit power on the unit resource corresponding to the second power convergence capability is less than or equal to the maximum transmit power on the unit resource corresponding to the first power convergence capability.

[0040] In a possible implementation method, when the start time of each cycle arrives, the feedback information is sent to the second device.

[0041] In a possible implementation method, when the working state of the first device changes, the feedback information is sent to the second device.

[0062] Figure 1(a) shows a possible, non-limiting schematic diagram of a communication system. As shown in Figure 1(a), communication system 1000 includes a radio access network (RAN) 100, a core network (CN) 200, and the Internet 300. RAN 100 includes at least one RAN node (e.g., 110a and 110b in Figure 1(a), collectively referred to as 110) and at least one terminal (e.g., 120a-120j in Figure 1(a), collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment (not shown in Figure 1(a)). Terminal 120 is wirelessly connected to RAN node 110. RAN node 110 is wirelessly or wiredly connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be separate physical devices, or they can be the same physical device that integrates core network logical functions and radio access network logical functions.

[0063] The RAN 100 may be a cellular system related to the Third Generation Partnership Project (3GPP), such as a fourth-generation (4G) or fifth-generation (5G) mobile communication system, or a future-oriented evolutionary system (such as a sixth-generation (6G) mobile communication system). The RAN 100 may also be an open access network (O-RAN or ORAN) or a wireless fidelity (WiFi) system. The RAN 100 may also be a communication system that integrates two or more of the above systems.

[0064] RAN node 110, sometimes also referred to as access network equipment, RAN entity, or access node, constitutes part of the communication system and facilitates wireless access for terminals. Multiple RAN nodes 110 in communication system 1000 can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative. For example, network element 120i in Figure 1(a) can be a helicopter or drone, which can be configured as a mobile base station. For terminal 120j accessing RAN 100 via network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes referred to as communication devices. For example, network elements 110a and 110b in Figure 1(a) can be understood as communication devices with base station functionality, and network elements 120a-120j can be understood as communication devices with terminal functionality.

[0065] In one possible scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB), a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node can be a macro base station (such as 110a in Figure 1(a)), a micro base station or an indoor station (such as 110b in Figure 1(a)), a relay node or a donor node, or a wireless controller in a cloud radio access network (CRAN) scenario. Optionally, a RAN node can also be a server, a wearable device, a vehicle, or an onboard device. For example, the access network device in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0066] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), a remote radio head (RRH), or an active antenna unit (AAU).

[0067] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0068] Figure 1(b) shows a schematic diagram of an access network device. As shown in Figure 1(b), the access network device includes one or more CUs, one or more DUs, and one or more radio units (RUs). For clarity, Figure 1(b) shows only one CU, DU, and RU. The CU is used to connect to the core network and one or more DUs. Optionally, the CU can have some of the core network's functions. The CU may include a CU-CP and a CU-UP.

[0069] The CU and DU can be configured according to the protocol layer functions of the wireless network they implement: for example, the CU is configured to implement the functions of the packet data convergence protocol (PDCP) layer and the protocol layers above it (such as the radio resource control (RRC) layer and / or the service data adaptation protocol (SDAP) layer, etc.); the DU is configured to implement the functions of the protocol layers below the PDCP layer (such as the radio link control (RLC) layer, the medium access control (MAC) layer, and / or the physical (PHY) layer, etc.). For another example, the CU is configured to implement the functions of the protocol layers above the PDCP layer (such as the RRC layer and / or the SDAP layer), and the DU is configured to implement the functions of the PDCP layer and the protocol layers below it (such as the RLC layer, the MAC layer, and / or the PHY layer, etc.).

[0070] The above configuration of CU and DU is only an example, and the functions of CU and DU can also be configured as needed. For example, the CU or DU can be configured to have the functions of more protocol layers, or the CU or DU can be configured to have partial processing functions of the protocol layer. For example, some functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU. For another example, the functions of the CU or DU can be divided according to the service type or other system requirements, such as by delay, and the functions whose processing time needs to meet the smaller delay requirement are set in the DU, and the functions that do not need to meet the delay requirement are set in the CU.

[0071] The DU and RU can work together to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of the DU and RU can be configured in various ways according to the design. For example, the DU is configured to implement the baseband function, and the RU is configured to implement the mid-RF function. For another example, the DU is configured to implement the high-layer functions in the PHY layer, and the RU is configured to implement the low-layer functions in the PHY layer or to implement the low-layer functions and the RF functions. The high-layer functions in the physical layer may include a part of the functions of the physical layer, which is closer to the MAC layer, and the low-layer functions in the physical layer may include another part of the functions of the physical layer, which is closer to the mid-RF side.

[0072] Figure 1(c) is a schematic diagram of a communication system provided in an embodiment of the present application. The communication system includes a first device and a second device. The embodiment of the present application does not limit the specific forms of the first device and the second device.

[0073] Exemplarily, the first device is any one of RU, RRU, and AAU, the second device is any one of CU, DU, and BBU, and the first device and the second device are two different devices.

[0074] Exemplarily, when the first device and the second device communicate using optical fiber, the interface between the first device and the second device can be a common public radio interface (CPRI) interface, an enhanced common public radio interface (eCPRI) interface, or a fronthaul interface.

[0075] Exemplarily, when the first device and the second device adopt wireless communication, the interface between the first device and the second device can be a 4G air interface, a 5G air interface, or a 6G air interface, etc.

[0076] In a non-power convergence scenario, the maximum transmit power per unit resource is fixed, and the sum of the actual transmit power per unit resource does not exceed the maximum transmit power of the device. The unit resource here can be a resource block (RB) or a resource element (RE), where one RB includes 12 REs. For ease of explanation, the following explanation will take the RE as an example of the unit resource. Figure 2(a) is an example diagram of power distribution in the non-power convergence scenario provided in an embodiment of the present application. In this example, it is assumed that the maximum transmit power of the device is P total , the total bandwidth is 100M. Since 100M corresponds to 273 RBs and each RB includes 12 REs, 100M corresponds to 273*12 REs. Define "reference power" P base P is the average transmit power of the signal (or data) sent by the device in each RE. base =P total / (273*12). In non-power aggregation scenarios, the maximum transmit power P of the signal (or data) sent by the device per RE is max That is the "reference power", or P max =P base Figure 2(a) shows a scenario where the device transmits at full power. In this scenario, the device transmits at P in each RE. base Data is sent with a transmission power of .

[0077] In a non-power convergence scenario, if full bandwidth scheduling is used, the device is configured to use the reference power P in each RE. baseWhen data is sent, the device sends data at the maximum transmission power (or full power), and the transmission power of the device can be fully utilized. However, the actual business situation is not always full bandwidth for data transmission. In some scenarios, some REs may not have data to be sent. At this time, other REs that carry data still send data according to the reference power of RE, resulting in a large amount of remaining power of the device that cannot be fully utilized. Figure 2 (b) is another example diagram of power distribution during non-power convergence provided by an embodiment of the present application. This example is based on Figure 2 (a) and shows a scenario when there is no data to be sent on some REs (REs shown in the dotted box in the figure). In this scenario, the maximum transmission power of other REs that carry data (REs in the shaded part) is still P base , resulting in the actual total transmission power of the device being less than or much less than P total , so the transmission power of the device cannot be fully utilized.

[0078] In order to make full use of the transmission power of the device, the present application proposes a power aggregation (PA) scheme, that is, under the premise of not exceeding the maximum transmission power of the device, the maximum transmission power of the signal (or data) sent by the device in some REs is increased, so that the remaining power of the device can be fully utilized. Figure 2 (c) is an example diagram of power distribution during power aggregation provided by an embodiment of the present application. In this example, when some REs do not carry data, the power saved by the part of REs can be used to increase the transmission power of other REs that carry data. For example, in Figure 2 (c), the maximum transmission power P of the signal (or data) sent by the device in some REs is max Can reach 2*P base , and the total transmission power of the device still does not exceed P total .

[0079] The power aggregation capability of a device is defined as the maximum transmit power P of the signal (or data) sent by the device per RE. max Relative to the "reference power" P base The ratio is generally expressed in decibel (dB) domain, that is, power aggregation capability = 10*lg(P max / P base For example, in the example of Figure 2(c), when the power aggregation capability of the device is 3dB, it means that the maximum transmission power P of the signal (or data) sent by the device in each RE is max Can be made by P base Increase to 2*P base , that is, 10*lg(2*P base / P base )=3dB.

[0080] When a device has power aggregation capabilities, it can bring the following benefits:

[0081] 1) Coverage improvement: Since the beams of different channels are designed independently, the beam gains and demodulation capabilities of different channels are different, resulting in different coverage capabilities of different channels. Power aggregation can improve the coverage capabilities of some channels.

[0082] 2) Coverage compensation: When various functions / features take effect and cause the beam to become wider, the beam coverage will deteriorate. Power convergence can compensate for some of the beam coverage loss.

[0083] 3) Experience improvement: For ordinary business transmission, power aggregation can improve the downlink experience rate.

[0084] Power aggregation can provide the above benefits, but improper power aggregation settings can degrade device performance. For example, if the device's power aggregation is set too high, it may result in more sudden peaks in service data, preventing the device from clipping them in time. This can cause signal distortion and affect air interface performance. Furthermore, the missed peaks can negatively impact analog components such as power amplifiers, shortening the device's lifespan or even damaging it. To ensure normal device operation, one approach to setting the device's power aggregation is to set a fixed and conservative power aggregation setting to ensure that the device can operate normally in various service scenarios without degrading its performance.

[0085] However, the aforementioned power aggregation configuration may result in the device's transmit power still not being fully utilized. That is, after power aggregation, the sum of the actual transmit power of each RE is still less than or significantly less than the device's maximum transmit power. Therefore, how to further improve the device's transmit power utilization remains to be solved.

[0086] FIG3 is a flow chart of a communication method provided in an embodiment of the present application. The method can be used to improve the utilization rate of the transmission power of a first device. The first device is an example of the aforementioned device.

[0087] The method comprises the following steps:

[0088] Step 301: The second device sends first data to the first device according to the first power aggregation capability of the first device.

[0089] The first device and the second device may refer to the description of the first device and the second device shown in FIG1( c ) respectively.

[0090] In one implementation method, if the first power aggregation capability is the initial power aggregation capability of the first device, then before step 301, the first device may send the first power aggregation capability to the second device.

[0091] In yet another implementation method, the first power aggregation capability is a default initial power aggregation capability of the first device.

[0092] For example, the first power aggregation capability may be set to 0 dB by default.

[0093] Among them, the second device sends the first data to the first device according to the first power aggregation capability of the first device, which means that when the second device sends the first data to the first device, it controls the transmission power of the data carried on each RE according to the first power aggregation capability to maximize the utilization of the transmission power of the first device.

[0094] Step 302: The first device sends feedback information to the second device. Correspondingly, the second device receives the feedback information.

[0095] The feedback information is used to reflect the working state of the first device when the power aggregation capability of the first device is the first power aggregation capability, that is, the working state of the first device when the second device sends the first data to the first device according to the first power aggregation capability, and the working state is normal or alarm. For example, when the maximum transmit power per unit resource corresponding to the first power aggregation capability is very large (for example, greater than a threshold value 1), resulting in the actual transmit power on some REs being relatively large (for example, greater than a threshold value 2), it may cause the working state of the first device to be alarm (or abnormal).

[0096] In this application, the feedback information may include at least one of the following information:

[0097] 1) Status information of the first device, where the status information is used to indicate the working status of the first device, where the working status is normal or alarm.

[0098] 2) indicator information of the first device, the indicator information comprising at least one of a crest factor reduction (CFR) dropout rate, a digital predistortion (DPD) convergence state, or an error vector magnitude (EVM) value.

[0099] The CFR leak clipping rate is used to indicate the proportion of peaks that are missed when the first device performs clipping processing. The lower the CFR leak clipping rate, the better the reliability of the device.

[0100] The DPD convergence status indicates the effectiveness of out-of-band spectrum leakage suppression. Convergence indicates good suppression, while non-convergence indicates poor suppression.

[0101] The EVM value is used to indicate the distortion of the data (the deviation between the actual data and the ideal data). The larger the EVM value, the more distorted the data, and the smaller the EVM value, the smaller the data distortion.

[0102] 3) Indication information, where the indication information is used to indicate whether to increase or decrease the power aggregation capability of the first device.

[0103] When the first device determines that the working state is normal, it can send instruction information to the second device to instruct it to increase the power aggregation capability of the first device. When the first device determines that the working state is alarm, it can send instruction information to the second device to instruct it to decrease the power aggregation capability of the first device.

[0104] In one implementation method, the first device can report feedback information based on a preset period, for example, reporting feedback information once every first time period, so when the start time of each period is reached, the first device sends feedback information to the second device, and the feedback information is used to reflect the current working status of the first device.

[0105] In another implementation method, the first device can report feedback information based on events. For example, when the working status of the first device changes (for example, from a normal state to an alarm state, or from an alarm state to a normal state), the first device sends feedback information to the second device. The feedback information is used to reflect the current working status of the first device.

[0106] Step 303: The second device sends second data to the first device according to the second power aggregation capability of the first device.

[0107] After receiving the feedback information corresponding to the first power aggregation capability, the second device determines the second power aggregation capability of the first device based on the feedback information and the first power aggregation capability.

[0108] In one implementation method, when the feedback information includes status information and the status information indicates that the operating status of the first device is normal, the second device may increase the power aggregation capability of the first device according to a certain step size, such as by 0.1 dB, so that the maximum transmit power per unit resource corresponding to the increased second power aggregation capability is greater than the maximum transmit power per unit resource corresponding to the first power aggregation capability. The "certain step size" here can be a fixed step size or a dynamically changing step size, which is not limited in this application. This is described uniformly here and will not be repeated later. Alternatively, the second device may not adjust the power aggregation capability of the first device when the number of normal times does not reach the normal times threshold, so that the maximum transmit power per unit resource corresponding to the second power aggregation capability is equal to the maximum transmit power per unit resource corresponding to the first power aggregation capability. Subsequently, when the number of normal times reaches the normal times threshold, the second device increases the power aggregation capability of the first device according to a certain step size. The "normal times" here refers to the number of times that the indication information indicating that the operating status of the first device is normal is received. For example, when the normal times threshold is 3, the second device increases the power aggregation capability of the first device according to a certain step size every three times it receives the indication information indicating that the operating status of the first device is normal.

[0109] In another implementation method, when the feedback information includes status information and the status information indicates that the working status of the first device is an alarm, the second device can reduce the power aggregation capability of the first device according to a certain step size, such as reducing it by 0.1 dB, so that the maximum transmit power per unit resource corresponding to the second power aggregation capability after the reduction is less than the maximum transmit power per unit resource corresponding to the first power aggregation capability. Alternatively, the second device may not adjust the power aggregation capability of the first device when the number of alarms does not reach the alarm number threshold, and the maximum transmit power per unit resource corresponding to the second power aggregation capability is equal to the maximum transmit power per unit resource corresponding to the first power aggregation capability. Subsequently, when the number of alarms reaches the alarm number threshold, the second device reduces the power aggregation capability of the first device according to a certain step size. The "number of alarms" here refers to the number of times the indication information indicating that the working status of the first device is an alarm is received. For example, when the alarm number threshold is equal to 3, the second device reduces the power aggregation capability of the first device according to a certain step size every time it receives the indication information indicating that the working status of the first device is an alarm three times.

[0110] In one implementation method, if the feedback information includes indicator information and the indicator information meets a first condition, the second device may increase the power aggregation capability of the first device according to a certain step size, for example, by 0.1 dB. Therefore, the maximum transmit power per unit resource corresponding to the increased second power aggregation capability is greater than the maximum transmit power per unit resource corresponding to the first power aggregation capability. Alternatively, the second device may not adjust the power aggregation capability of the first device until the number of times the indicator information reported by the first device meets the first condition reaches a first threshold, in which case the maximum transmit power per unit resource corresponding to the second power aggregation capability is equal to the maximum transmit power per unit resource corresponding to the first power aggregation capability. Subsequently, when the number of times the indicator information reported by the first device meets the first condition reaches the first threshold, the second device increases the power aggregation capability of the first device according to a certain step size. For example, if the first threshold is 5, the second device increases the power aggregation capability of the first device every five times the received indicator information meets the first condition. The first condition includes at least one of the following: the CFR drop rate is lower than the drop rate threshold, the DPD convergence state is converged, or the EVM value is lower than the EVM threshold.

[0111] In another implementation method, when the feedback information includes indicator information and the indicator information does not meet the above-mentioned first condition, the second device can reduce the power convergence capability of the first device according to a certain step size, such as reducing it by 0.1dB, so that the maximum transmit power per unit resource corresponding to the reduced second power convergence capability is less than the maximum transmit power per unit resource corresponding to the first power convergence capability. Alternatively, the second device may not adjust the power convergence capability of the first device before the number of times the indicator information reported by the first device does not meet the above-mentioned first condition reaches the first threshold, then the maximum transmit power per unit resource corresponding to the second power convergence capability is equal to the maximum transmit power per unit resource corresponding to the first power convergence capability. Subsequently, when the number of times the indicator information reported by the first device does not meet the above-mentioned first condition reaches the first threshold, the second device reduces the power convergence capability of the first device according to a certain step size. Taking the first threshold as 5 as an example, every time the indicator information received does not meet the above-mentioned first condition for 5 times, the second device reduces the power convergence capability of the first device once.

[0112] In one implementation method, when the feedback information includes indication information and the indication information indicates to increase the power convergence capability of the first device, the second device may increase the power convergence capability of the first device according to a certain step size, such as increasing by 0.1dB, so that the maximum transmit power per unit resource corresponding to the increased second power convergence capability is greater than the maximum transmit power per unit resource corresponding to the first power convergence capability. Alternatively, the second device may not adjust the power convergence capability of the first device before the number of indication information received for indicating to increase the power convergence capability of the first device reaches a second threshold, then the maximum transmit power per unit resource corresponding to the second power convergence capability is equal to the maximum transmit power per unit resource corresponding to the first power convergence capability. Subsequently, when the number of indication information received by the second device for indicating to increase the power convergence capability of the first device reaches the second threshold, the second device increases the power convergence capability of the first device according to a certain step size. Taking the second threshold as 5 as an example, the second device increases the power convergence capability of the first device once every time it receives 5 indication information for indicating to increase the power convergence capability of the first device.

[0113] In another implementation method, when the feedback information includes indication information and the indication information indicates to lower the power convergence capability of the first device, the second device may lower the power convergence capability of the first device according to a certain step size, such as reducing it by 0.1 dB, so that the maximum transmit power per unit resource corresponding to the second power convergence capability after the reduction is less than the maximum transmit power per unit resource corresponding to the first power convergence capability. Alternatively, the second device may not adjust the power convergence capability of the first device before the number of indication information received for indicating to lower the power convergence capability of the first device reaches a second threshold, then the maximum transmit power per unit resource corresponding to the second power convergence capability is equal to the maximum transmit power per unit resource corresponding to the first power convergence capability. Subsequently, when the number of indication information received by the second device for indicating to lower the power convergence capability of the first device reaches the second threshold, the second device lowers the power convergence capability of the first device according to a certain step size. Taking the second threshold as 5 as an example, the second device lowers the power convergence capability of the first device once every time it receives 5 indication information for indicating to lower the power convergence capability of the first device.

[0114] The above gives different implementation methods for the second device to adjust the power convergence capability of the first device. In actual applications, it is not limited to the above methods. For example, two or three of the above status information, indicator information, and indication information can be combined to determine whether to adjust and how to adjust the power convergence capability of the first device.

[0115] In one implementation method, when the above-mentioned first data and second data are both data of the first business, the second device can also establish a correspondence between the second power convergence capability and the characteristic information of the first business based on the characteristic information of the first business. The characteristic information of the first business includes one or more of the following: the distribution characteristics of the data of the first business in the frequency domain, the power distribution corresponding to the data of the first business. For example, after the second device adjusts the power convergence capability of the first device multiple times, the feedback information received for N consecutive times (N is an integer greater than or equal to 1) indicates that the working state of the first device is normal, and the feedback information received for the N+1th time indicates that the working state of the first device is an alarm, then the second device can record the power convergence capability (such as the second power convergence capability) corresponding to the feedback information received for the Nth time, and specifically, record the correspondence between the second power convergence capability and the characteristic information of the first business. Subsequently, when the second device sends the data of the first business, it obtains the corresponding power convergence capability of the first device (i.e., the second power convergence capability) based on the characteristic information of the first business, and then uses the second power convergence capability to send the data of the first business, without the need to dynamically adjust the power convergence capability of the first device according to the above scheme of this application. This can bring the following benefits: first, it can reduce the power consumption and resource overhead of the first device and the second device due to dynamic adjustment; second, it can avoid the first device from being shortened or even damaged due to frequent alarms caused by dynamic adjustment.

[0116] The above scheme dynamically adjusts the power aggregation capability of the first device according to the feedback information of the first device, can reasonably determine the power aggregation capability of the first device, and helps to improve the utilization rate of the transmission power of the first device while ensuring the normal operation of the first device.

[0117] FIG4 is an example diagram of power distribution during power convergence provided by an embodiment of the present application. Compared with FIG2(c), in the example of FIG4, the maximum transmission power P of the signal (or data) sent by the first device on each RE is max By 2*P base Increased to 4*P base , or it can be understood that the power convergence capability is improved by 3dB on the basis of Figure 2(c), that is, before the adjustment, the power convergence capability of the first device (i.e., the first power convergence capability) is 3dB, and after the adjustment, the power convergence capability of the first device (i.e., the second power convergence capability) is 6dB.
