Description

[Technical Field]

[0001] Embodiments of this application relate to the field of wireless communication technology, and more particularly to communication methods, communication devices, and communication systems. [Background technology]

[0002] When a device transmits data, it cannot exceed the device's maximum transmission power; that is, the sum of the transmission power of the unit resources carrying the data cannot exceed the device's maximum transmission power.

[0003] To maximize the device's transmission power, data is typically transmitted at a power level close to the device's maximum transmission power during actual transmission.

[0004] Therefore, a crucial issue is how to improve the utilization of the device's transmitted power. [Overview of the project]

[0005] Embodiments of this application provide a communication method, a communication device, and a communication system for improving the utilization of the power transmitted by a device.

[0006] According to a first aspect, an embodiment of the present application provides a communication method which may be performed by a second device or a module (e.g., a chip) in the second device. The method includes the steps of: transmitting 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 transmitting second data to the first device based on a second power aggregation capability of the first device, wherein the second power aggregation capability is determined based on the feedback information and the first power aggregation capability.

[0007] In the aforementioned solution, the power aggregation capacity of the first device is dynamically adjusted based on feedback information from the first device, thereby enabling the appropriate determination of the power aggregation capacity of the first device. This helps to improve the utilization of the transmission power of the first device while ensuring that the first device operates properly.

[0008] In possible implementations, a first power aggregation capacity is received from a first device, and this first power aggregation capacity is the initial power aggregation capacity of the first device.

[0009] In the solution described above, the first device reports its initial power aggregation capacity. This helps the second device determine a more appropriate power aggregation capacity for the first device based on its initial power aggregation capacity.

[0010] In possible implementations, the first power aggregation capacity is the default initial power aggregation capacity of the first device.

[0011] In the aforementioned solution, the initial power aggregation capacity of the first device is the default. Therefore, the first device does not need to report its initial power aggregation capacity to the second device. This helps reduce signaling overhead.

[0012] Where possible, feedback information will be provided. Status information of the first device, which indicates the operating status of the first device, and the operating status is normal or warning, status information of the first device, Indicator information of a first device, wherein this indicator information includes at least one of the following: crest factor reduction (CFR) missing clipping rate, digital predistortion (DPD) convergence status, or error vector magnitude (EVM) value, or Indication information, which indicates increasing or decreasing the power aggregation capacity of a first device. It includes at least one of the following.

[0013] In the aforementioned solution, the first device accurately reports its operating status to the second device using feedback information, thereby enabling the second device to accurately determine the mode for adjusting the power aggregation capacity of the first device based on the feedback information. This helps determine the appropriate power aggregation capacity.

[0014] In possible implementations, if the feedback information includes status information and the status information indicates that the operating status of the first device is normal, then the maximum transmission power on a unit resource corresponding to the second power aggregation capacity is equal to or greater than the maximum transmission power on a unit resource corresponding to the first power aggregation capacity; or if the feedback information includes status information and the status information indicates that the operating status of the first device is a warning, then the maximum transmission power on a unit resource corresponding to the second power aggregation capacity is equal to or less than the maximum transmission power on a unit resource corresponding to the first power aggregation capacity.

[0015] In a possible implementation method, the feedback information includes indicator information, and when the indicator information satisfies a first condition, the maximum transmission power on a unit resource corresponding to a second power aggregation capability is greater than or equal to the maximum transmission power on a unit resource corresponding to a first power aggregation capability; or when the feedback information includes indicator information and the indicator information does not satisfy the first condition, the maximum transmission power on a unit resource corresponding to the second power aggregation capability is less than or equal to the maximum transmission power on a unit resource corresponding to the first power aggregation capability, wherein the first condition includes at least one of: a missing clipping rate in CFR is less than a missing clipping rate threshold, a DPD convergence status is converged, or an EVM value is less than an EVM threshold.

[0016] In a possible implementation method, the feedback information includes indication information, and when the indication information indicates to increase the power aggregation capability of a first apparatus, the maximum transmission power on a unit resource corresponding to a second power aggregation capability is greater than or equal to the maximum transmission power on a unit resource corresponding to a first power aggregation capability; or when the feedback information includes indication information and the indication information indicates to decrease the power aggregation capability of the first apparatus, the maximum transmission power on a unit resource corresponding to the second power aggregation capability is less than or equal to the maximum transmission power on a unit resource corresponding to the first power aggregation capability.

[0017] In a possible implementation method, when both first data and second data are data of a first service, a correspondence between a second power aggregation capability and characteristic information of the first service is established based on the characteristic information of the first service.

[0018] In the foregoing solution, after the second device establishes the correspondence between the second power aggregation capability and the characteristic information of the first service, when the second device subsequently transmits data of the first service, the second device 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 transmits the data of the first service by using the second power aggregation capability. Accordingly, there is no need to dynamically adjust the power aggregation capability of the first device. In this approach, for the first device and the second device, power consumption and resource overhead caused by dynamic adjustment can be reduced, and for the first device, reduction or even damage to the service life caused by frequent alarms resulting from dynamic adjustment can be prevented.

[0019] In a possible implementation, the characteristic information of the first service includes one or more of a distribution characteristic of the data of the first service in a frequency domain, or power distribution corresponding to the data of the first service.

[0020] In a possible implementation, the feedback information is received based on periodicity or received based on event-based triggering.

[0021] According to a second aspect, embodiments of the present application provide a communication method. The method may be executed by a first device, or a module (e.g., a chip) in the first device. The method comprises: receiving first data from a second device, the first data corresponding to a first power aggregation capability of the first device; and transmitting feedback information to the second device, the feedback information reflecting an operation status of the first device when the power aggregation capability of the first device is the first power aggregation capability.

[0022] In the aforementioned solution, the power aggregation capacity of the first device is dynamically adjusted based on feedback information from the first device, thereby enabling the appropriate determination of the power aggregation capacity of the first device. This helps to improve the utilization of the transmission power of the first device while ensuring that the first device operates properly.

[0023] In possible implementations, the first power aggregation capacity is transmitted to the second device, and the first power aggregation capacity is the initial power aggregation capacity of the first device.

[0024] In the solution described above, the first device reports its initial power aggregation capacity. This helps the second device determine a more appropriate power aggregation capacity for the first device based on its initial power aggregation capacity.

[0025] In possible implementations, the first power aggregation capacity is the default initial power aggregation capacity of the first device.

[0026] In the aforementioned solution, the initial power aggregation capacity of the first device is the default. Therefore, the first device does not need to report its initial power aggregation capacity to the second device. This helps reduce signaling overhead.

[0027] In possible implementations, second data is received from a second device, the second data corresponds to a second power aggregation capacity of the first device, and the second power aggregation capacity is determined based on feedback information and the first power aggregation capacity.

[0028] Where possible, feedback information will be provided. Status information of the first device, which indicates the operating status of the first device, Indicator information of the first device, wherein this indicator information includes at least one of the following: missing clipping rate in CFR, DPD convergence status, or EVM value, or Indication information, which indicates increasing or decreasing the power aggregation capacity of a first device. It includes at least one of the following.

[0029] In the aforementioned solution, the first device accurately reports its operating status to the second device using feedback information, thereby enabling the second device to accurately determine the mode for adjusting the power aggregation capacity of the first device based on the feedback information. This helps determine the appropriate power aggregation capacity.

[0030] In possible implementations, if the feedback information includes status information and the status information indicates that the operating status of the first device is normal, then the maximum transmission power on a unit resource corresponding to the second power aggregation capacity is equal to or greater than the maximum transmission power on a unit resource corresponding to the first power aggregation capacity; or if the feedback information includes status information and the status information indicates that the operating status of the first device is a warning, then the maximum transmission power on a unit resource corresponding to the second power aggregation capacity is equal to or less than the maximum transmission power on a unit resource corresponding to the first power aggregation capacity.

[0031] In possible implementations, if the feedback information includes indicator information and the indicator information satisfies the first condition, the maximum transmission power on a unit resource corresponding to the second power aggregation capacity is equal to or greater than the maximum transmission power on a unit resource corresponding to the first power aggregation capacity; or if the feedback information includes indicator information and the indicator information does not satisfy the first condition, the maximum transmission power on a unit resource corresponding to the second power aggregation capacity is equal to or less than the maximum transmission power on a unit resource corresponding to the first power aggregation capacity, the first condition includes at least one of the following: the missing clipping rate in the CFR is less than the missing clipping rate threshold, the DPD convergence status is converged, or the EVM value is less than the EVM threshold.

[0032] In possible implementations, if the feedback information includes indication information and the indication information indicates an increase in the power aggregation capacity of the first device, then the maximum transmission power on a unit resource corresponding to the second power aggregation capacity is equal to or greater than the maximum transmission power on a unit resource corresponding to the first power aggregation capacity; or, if the feedback information includes indication information and the indication information indicates a decrease in the power aggregation capacity of the first device, then the maximum transmission power on a unit resource corresponding to the second power aggregation capacity is equal to or less than the maximum transmission power on a unit resource corresponding to the first power aggregation capacity.

[0033] In possible implementations, feedback information is sent to the second device when the start time of each period arrives.

[0034] In possible implementations, feedback information is sent to the second device when the operating status of the first device changes.

[Figure 6] This is a diagram of a communication device according to an embodiment of the present application. [Modes for carrying out the invention]

[0046] Figure 1(a) is a diagram of a possible, non-limiting communication system. As shown in Figure 1(a), the communication system 1000 includes a radio access network (RAN) 100, a core network (CN) 200, and the Internet 300. The 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 through 120j in Figure 1(a), collectively referred to as 120). The RAN 100 may further include other RAN nodes, e.g., wireless relay devices and / or wireless backhaul devices (not shown in Figure 1(a)). The terminal 120 is connected to the RAN node 110 wirelessly. The RAN node 110 is connected to the core network 200 wirelessly or via a wired connection. The core network devices in core network 200 and the RAN node 110 in RAN 100 may be different physical devices, or they may be the same physical device integrating the logical functions of the core network and the logical functions of the wireless access network.

[0047] RAN 100 is the third-generation partnership project (3 rd Cellular systems related to the Generation Partnership Project (3GPP), for example, fourth generation (4 th generation (4G) or fifth generation (5 th Mobile communication systems (e.g., 6th generation, 5G), or future-oriented evolutionary systems (e.g., 6th generation (6G) th RAN 100 may be a mobile communication system of generation 6G. Alternatively, RAN 100 may be an open access network (open RAN, O-RAN, or ORAN) or a wireless fidelity (Wi-Fi) system. Alternatively, RAN 100 may be a communication system that integrates two or more of the aforementioned systems.

[0048] RAN nodes 110, sometimes referred to as access network devices, RAN entities, or access nodes, are part of a communication system and are configured to assist terminals in performing radio access. Multiple RAN nodes 110 in the communication system 1000 may be the same type of node or different types of nodes. In some scenarios, the roles of RAN nodes 110 and terminals 120 are relative. For example, in Figure 1(a), network element 120i may be a helicopter or unmanned aerial vehicle, and network element 120i may be configured as a mobile base station. For terminal 120j, which is connected to RAN 100 by using network element 120i, network element 120i is a base station. However, for base station 110a, network element 120i is a terminal. RAN nodes 110 and terminals 120 are sometimes both referred to as communication devices. For example, in Figure 1(a), network elements 110a and 110b can be understood as communication devices having the function of a base station, and network elements 120a to 120j can be understood as communication devices having the function of a terminal.

[0049] In possible scenarios, a RAN node could 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 Wi-Fi system. A RAN node could be a macro base station (e.g., 110a in Figure 1(a)), a micro base station or indoor station (e.g., 110b in Figure 1(a)), a relay node or donor node, or a radio controller in a cloud radio access network (CRAN) scenario. Optionally, a RAN node could also be a server, a wearable device, a vehicle, or an in-vehicle device. For example, an access network device in vehicle-to-everything (V2X) technology could be a roadside unit (RSU).

[0050] In another possible scenario, multiple RAN nodes collaborate to assist terminals in implementing radio access, with different RAN nodes independently performing several base station functions. For example, RAN nodes could be a central unit (CU), a distributed unit (DU), a CU control plane (CP), a CU user plane (UP), or a radio unit (RU). CUs and DUs may be located separately or be included in the same network element, such as a baseband unit (BBU). RUs may be included in radio frequency devices or radio frequency units, such as a remote radio unit (RRU), a remote radio head (RRH), or an active antenna unit (AAU).

[0051] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand the meaning of these names. For example, in the ORAN system, CU may be called O-CU (open CU), DU may be called O-DU, CU-CP may be called O-CU-CP, CU-UP may be called O-CU-UP, and RU may be called O-RU. For ease of description, in this application CU, CU-CP, CU-UP, DU, and RU are used as examples for description. Any of CU (or CU-CP and CU-UP), DU, and RU in this application may be implemented using software modules, hardware modules, or a combination thereof.

[0052] Figure 1(b) is a 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, one DU, and one RU. The CU is configured to connect to the core network and one or more DUs. Optionally, the CU may have several functions of the core network. The CU may include CU-CP and CU-UP.

[0053] CUs and DUs may be configured based on the functions of the wireless network's protocol layer that they will perform. For example, a CU may be configured to perform functions of the packet data convergence protocol (PDCP) layer and higher-level protocol layers (e.g., the radio resource control (RRC) layer and / or the service data adaptation protocol (SDAP) layer), while a DU may be configured to perform functions of lower-level protocol layers than the PDCP layer (e.g., the radio link control (RLC) layer, the medium access control (MAC) layer, and / or the physical (PHY) layer). Another example is a CU being configured to perform functions of higher-level protocol layers than the PDCP layer (e.g., the RRC layer and / or the SDAP layer), while a DU being configured to perform functions of the PDCP layer and lower-level protocol layers (e.g., the RLC layer, the MAC layer, and / or the PHY layer).

[0054] The aforementioned configurations of CUs and DUs are merely examples. Alternatively, the functions of CUs and DUs can be configured according to requirements. For example, a CU or DU may be configured to have more protocol layer functions, or a CU or DU may be configured to have some of the processing functions of a protocol layer. For example, some functions of the RLC layer and functions of higher protocol layers than the RLC layer may be configured on the CU, while the remaining functions of the RLC layer and functions of lower protocol layers than the RLC layer may be configured on the DU. As another example, functions may be split between the CU and DU based on service type or other system requirements. For example, splitting may be done based on latency. Functions with processing times that need to meet low latency requirements may be configured on the DU, while functions with processing times that do not need to meet those latency requirements may be configured on the CU.

[0055] DUs and RUs can work together to jointly perform functions of the PHY layer. One DU may be connected to one or more RUs. The functions of DUs and RUs can be configured in multiple ways depending on the design. For example, a DU may be configured to perform baseband functions, and an RU may be configured to perform intermediate radio frequency functions. Another example is a DU being configured to perform higher-level functions of the PHY layer, and an RU being configured to perform lower-level functions of the PHY layer, or to perform both those lower-level functions and radio frequency functions. The higher-level functions of the physical layer may include some functions of the physical layer, these functions being closer to the MAC layer. The lower-level functions of the physical layer may include other functions of the physical layer, these functions being closer to the intermediate radio frequency side.

[0056] Figure 1(c) is a diagram of a communication system according to an embodiment of the present application. This communication system includes a first device and a second device. The specific forms of the first and second devices are not limited in this embodiment of the present application.

[0057] For example, the first device is one of RU, RRU, or AAU, the second device is one of CU, DU, or BBU, and the first and second devices are two different devices.

[0058] For example, if the first device communicates with the second device using optical fiber, the interface between the first and second devices could be a common public radio interface (CPRI), an enhanced common public radio interface (eCPRI), a fronthaul interface, or the like.

[0059] For example, when wireless communication is performed between a first device and a second device, the interface between the first device and the second device may be a 4G air interface, a 5G air interface, a 6G air interface, etc.

[0060] In a non-power-aggregated scenario, the maximum transmission power on a unit resource is fixed, and the sum of the actual transmission powers for a unit resource does not exceed the maximum transmission power of the device. Here, a unit resource can be a resource block (RB) or a resource element (RE), where one RB contains 12 REs. For ease of description, RE will be used as an example of a unit resource for description purposes. Figure 2(a) is a diagram illustrating an example of power distribution in a non-power-aggregated case according to an embodiment of the present application. In this example, the maximum transmission power of the device is P total Therefore, the total bandwidth is assumed to be 100M(M). 100M corresponds to 273 RBs, and each RB contains 12 REs, so 100M corresponds to 273 × 12 REs. "Reference power" P base P is defined as the average transmission power used by the device to transmit signals (or data) on each RE, base =P total / (273×12). In a non-power-intensive scenario, the maximum transmit power P for transmitting a signal (or data) on each resource element by a device max is the "reference power", that is, P max =P base . Figure 2(a) shows a scenario of full-power transmission by a device. In this scenario, the device transmits data at transmit power P on each RE base .

[0061] In a non-power-intensive scenario, when the device transmits data on each RE at reference power P in the case of full bandwidth scheduling base , the device transmits data at the maximum transmit power (or full power). In this case, the transmit power of the device can be utilized to the maximum extent. However, in actual service conditions, data is not always transmitted with the full bandwidth. In some scenarios, there may be no data that needs to be transmitted on some REs. In this case, data is still transmitted at the reference power of the corresponding REs on other REs that carry data. As a result, a large amount of remaining power of the device cannot be utilized to the maximum extent. Figure 2(b) is a diagram of another example of power allocation in the non-power-intensive case according to an embodiment of the present application. Based on Figure 2(a), this example shows a scenario where data does not need to be transmitted on some REs (REs indicated by dashed boxes in the figure). In this scenario, the maximum transmit power on other REs (shaded REs) that carry data is still P base . As a result, the actual total transmit power of the device is smaller than, or significantly smaller than P total . Therefore, the transmit power of the device cannot be utilized to the maximum extent.

[0062] To maximize the utilization of a device's transmission power, this application provides a power aggregation (PA) solution. Specifically, provided that the maximum transmission power of the device is not exceeded, the maximum transmission power for transmitting signals (or data) on some REs can be increased by the device, thereby maximizing the utilization of the device's remaining power. Figure 2(c) shows an example of power distribution in the case of power aggregation according to an embodiment of this application. In this example, if some REs are not carrying data, the power saved by these REs can be used to increase the transmission power of other REs that are carrying data. For example, in Figure 2(c), the maximum transmission power P for transmitting signals (or data) on some of the REs by the device is... max However, 2×P base It can reach, and the total transmission power of the device is still P total It does not exceed [a certain limit].

[0063] The power aggregation capability of a device is defined as "reference power" P base The maximum transmission power P required by the device to transmit a signal (or data) on each RE. max It is defined as the ratio of and is usually expressed in the decibel (dB) range, i.e., Power aggregation capacity = 10 × lg(P max / P base ) For example, in the example in Figure 2(c), if the power aggregation capability of the device is 3dB, then it is the maximum transmission power P required by the device to transmit a signal (or data) over each RE. max However, P base From 2×P base It can be increased to, that is, 10 × lg(2 × P base / P base This indicates that ) = 3dB.

[0064] If the device has power aggregation capabilities, the following advantages may be obtained:

[0065] (1) Improved coverage: Since the beams are designed independently for each channel, the beam gain and demodulation capability differ for each channel, resulting in different coverage capabilities for different channels. Power aggregation can improve the coverage capability of some channels.

[0066] (2) Coverage compensation: When the beam is broadened due to the effects of various functions / features, beam coverage deteriorates. Power aggregation can compensate for the coverage loss of some beams.

[0067] (3) Improved experience: For general service transmissions, power aggregation can increase the downlink experience rate.

[0068] Power aggregation can provide the aforementioned benefits. However, setting an inappropriate power aggregation capacity can lead to a decrease in device performance. For example, if a device's power aggregation capacity is set to a high value, there may be large bursts of service data, and the device may not be able to perform clipping in a timely manner. As a result, signal distortion occurs, affecting the performance of the air interface, and the peaks that are missed during clipping may adversely affect analog devices such as power amplifiers, thereby affecting the lifespan of the device or even causing damage to the device. To ensure the normal operation of the device, the way in which the device's power aggregation capacity is set should be to set a fixed, modest power aggregation capacity to ensure that the device can operate properly in various service scenarios and that the device performance does not degrade.

[0069] However, the aforementioned power aggregation capability setting method may still result in the device's transmission power not being utilized to its fullest extent, meaning that after power aggregation, the total actual transmission power of the REs may still be less than or significantly less than the device's maximum transmission power. Therefore, how to further improve the utilization of the device's transmission power needs to be addressed.

[0070] Figure 3 is a schematic flowchart of a communication method according to an embodiment of the present application. This method can be used to improve the utilization of the transmission power of a first device. The first device is an example of the device described above.

[0071] This method includes the following steps.

[0072] Step 301: The second device transmits the first data to the first device based on the first power aggregation capacity of the first device.

[0073] For the first and second devices, please refer to the descriptions of the first and second devices shown in Figure 1(c), respectively.

[0074] In the implementation method, if the first power aggregation capacity is the initial power aggregation capacity of the first device, the first device may transmit the first power aggregation capacity to the second device before step 301.

[0075] In another implementation, the first power aggregation capacity is the default initial power aggregation capacity of the first device.

[0076] For example, the first power aggregation capacity can be 0 dB by default.

[0077] The transmission of first data by the second device to the first device based on the first power aggregation capacity of the first device means that, when transmitting the first data to the first device, the second device controls the transmission power for the data carried on each RE based on the first power aggregation capacity to maximize the use of the transmission power of the first device.

[0078] Step 302: The first device transmits feedback information to the second device, and the second device receives the feedback information in response.

[0079] The feedback information reflects the operational status of the first device when its power aggregation capacity is the first power aggregation capacity, i.e., the operational status of the first device when the second device transmits the first data to the first device based on the first power aggregation capacity. The operational status is normal or warning. For example, if the maximum transmission power on a unit resource corresponding to the first power aggregation capacity is excessively high (e.g., greater than threshold 1), then the actual transmission power on some REs will be high as a result (e.g., greater than threshold 2). As a result, the operational status of the first device may be warning (or abnormal).

[0080] In this application, the feedback information may include at least one of the following pieces of information:

[0081] (1) Status information of the first device, this status information indicates the operating status of the first device, and the operating status is normal or warning.

[0082] (2) Indicator information of the first device, which includes at least one of the following: crest factor reduction (CFR) missing clipping rate, digital predistortion (DPD) convergence status, or error vector magnitude (EVM) value.

[0083] The CFR clipping rate indicates the percentage of peaks lost during clipping performed by the first device. A lower CFR clipping rate indicates higher device reliability.

[0084] The DPD convergence status indicates the effectiveness of suppressing out-of-band spectral leakage. If the DPD converges, it indicates a good suppression effect. If the DPD does not converge, it indicates a poor suppression effect.

[0085] The EVM value indicates the degree of data distortion (the deviation between actual data and ideal data). A larger EVM value indicates more severe data distortion, while a smaller EVM value indicates less distortion.

[0086] (3) Indication information, which indicates increasing or decreasing the power aggregation capacity of the first device.

[0087] If the operating status is determined to be normal, the first device may send indication information to the second device indicating that the first device's power aggregation capacity should be increased. If the operating status is determined to be a warning, the first device may send indication information to the second device indicating that the first device's power aggregation capacity should be decreased.

[0088] In the implementation method, the first device may report feedback information based on a predetermined cycle, for example, once per interval of a first duration. Therefore, when the start time of each period arrives, the first device transmits feedback information to the second device. The feedback information reflects the current operating status of the first device.

[0089] In an alternative implementation, the first device may report feedback information based on an event. For example, if the operating status of the first device changes (e.g., from normal to warning, or from warning to normal), the first device sends feedback information to the second device. The feedback information reflects the current operating status of the first device.

[0090] Step 303: The second device transmits the second data to the first device based on the second power aggregation capacity of the first device.

[0091] After receiving feedback information corresponding to the first power aggregation capacity, the second device determines the second power aggregation capacity of the first device based on the feedback information and the first power aggregation capacity.

[0092] In the implementation, if 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 capacity of the first device by a specific step, for example, by 0.1 dB. Thus, the maximum transmitted power on a unit resource corresponding to the increased second power aggregation capacity is greater than the maximum transmitted power on a unit resource corresponding to the first power aggregation capacity. Here, the “specific step” may be a fixed step or a dynamically changing step. This is not limited to the present application. This is described here in a unified style and the details will not be described again thereafter. Alternatively, the second device may not adjust the power aggregation capacity of the first device if the number of normal occurrences does not reach a threshold for the number of normal occurrences. In this case, the maximum transmitted power on a unit resource corresponding to the second power aggregation capacity is equal to the maximum transmitted power on a unit resource corresponding to the first power aggregation capacity. Subsequently, when the number of normal occurrences reaches the threshold for the number of normal occurrences, the second device increases the power aggregation capacity of the first device by a specific step. Here, the "number of normal occurrences" is the number of times the first device receives indication information that its operational status is normal. For example, if the threshold for the number of normal occurrences is equal to 3, the second device increases the power aggregation capacity of the first device by a specific step once for every three times it receives indication information that its operational status is normal.

[0093] In an alternative implementation, if feedback information includes status information and that status information indicates the operating status of the first device is a warning, the second device may reduce the power aggregation capacity of the first device by a specific step, for example, 0.1 dB. Thus, the maximum transmitted power on a unit resource corresponding to the reduced second power aggregation capacity is less than the maximum transmitted power on a unit resource corresponding to the first power aggregation capacity. Alternatively, the second device may not adjust the power aggregation capacity of the first device if the number of warnings does not reach a threshold for the number of warnings. In this case, the maximum transmitted power on a unit resource corresponding to the second power aggregation capacity is equal to the maximum transmitted power on a unit resource corresponding to the first power aggregation capacity. Subsequently, if the number of warnings reaches a threshold for the number of warnings, the second device reduces the power aggregation capacity of the first device by a specific step. Here, "number of warnings" is the number of times the device receives indication information that the operating status of the first device is a warning. For example, if the threshold for the number of warnings is equal to 3, the second device reduces the power aggregation capacity of the first device by a specific step once for every three times it receives indication information that the operating status of the first device is warning.

[0094] In the implementation method, if the feedback information includes indicator information and that indicator information satisfies the first condition, the second device may increase the power aggregation capacity of the first device by a specific step, for example, by 0.1 dB. Thus, the maximum transmitted power on a unit resource corresponding to the increased second power aggregation capacity is greater than the maximum transmitted power on a unit resource corresponding to the first power aggregation capacity. Alternatively, the second device does not need to adjust the power aggregation capacity of the first device before the number of times the indicator information reported by the first device satisfies the first condition reaches a first threshold. In this case, the maximum transmitted power on a unit resource corresponding to the second power aggregation capacity is equal to the maximum transmitted power on a unit resource corresponding to the first power aggregation capacity. Subsequently, if the number of times the indicator information reported by the first device satisfies the first condition reaches a first threshold, the second device increases the power aggregation capacity of the first device by a specific step. An example is used where the first threshold is 5. In this case, for every five times the second device receives indicator information that satisfies the first condition, the second device increases the power aggregation capacity of the first device by one. The first condition includes at least one of the following: the missing clipping rate in the CFR is less than the missing clipping rate threshold, the DPD convergence status is converged, or the EVM value is less than the EVM threshold.

[0095] In an alternative implementation, if the feedback information includes indicator information and that indicator information does not satisfy the first condition, the second device may reduce the power aggregation capacity of the first device by a specific step, for example, 0.1 dB. Thus, the maximum transmitted power on a unit resource corresponding to the reduced second power aggregation capacity is less than the maximum transmitted power on a unit resource corresponding to the first power aggregation capacity. Alternatively, the second device does not need to adjust the power aggregation capacity of the first device before the number of times the indicator information reported by the first device fails to satisfy the first condition reaches a first threshold. In this case, the maximum transmitted power on a unit resource corresponding to the second power aggregation capacity is equal to the maximum transmitted power on a unit resource corresponding to the first power aggregation capacity. Subsequently, if the number of times the indicator information reported by the first device fails to satisfy the first condition reaches the first threshold, the second device reduces the power aggregation capacity of the first device by a specific step. An example is used where the first threshold is 5. In this case, for every five times the second device receives indicator information that does not satisfy the first condition, the second device reduces the power aggregation capacity of the first device by one.

[0096] In the implementation method, if feedback information includes indication information that suggests increasing the power aggregation capacity of the first device, the second device may increase the power aggregation capacity of the first device by a specific step, for example, 0.1 dB. Therefore, the maximum transmitted power on a unit resource corresponding to the increased second power aggregation capacity is greater than the maximum transmitted power on a unit resource corresponding to the first power aggregation capacity. Alternatively, the second device does not need to adjust the power aggregation capacity of the first device before the amount of received indication information suggesting an increase in the power aggregation capacity of the first device reaches a second threshold. In this case, the maximum transmitted power on a unit resource corresponding to the second power aggregation capacity is equal to the maximum transmitted power on a unit resource corresponding to the first power aggregation capacity. Subsequently, if the amount of indication information received by the second device suggesting an increase in the power aggregation capacity of the first device reaches a second threshold, the second device increases the power aggregation capacity of the first device by a specific step. An example is used where the second threshold is 5. In this case, for every five indications the second device receives that indicate it should increase the power aggregation capacity of the first device, the second device increases the power aggregation capacity of the first device by 1.

[0097] In another implementation, if feedback information includes indication information that suggests reducing the power aggregation capacity of the first device, the second device may reduce the power aggregation capacity of the first device by a specific step, for example, 0.1 dB. Thus, the maximum transmitted power on a unit resource corresponding to the reduced second power aggregation capacity is less than the maximum transmitted power on a unit resource corresponding to the first power aggregation capacity. Alternatively, the second device may not adjust the power aggregation capacity of the first device before the amount of received indication information suggesting a reduction in the power aggregation capacity of the first device reaches a second threshold. In this case, the maximum transmitted power on a unit resource corresponding to the second power aggregation capacity is equal to the maximum transmitted power on a unit resource corresponding to the first power aggregation capacity. Subsequently, if the amount of indication information received by the second device suggesting a reduction in the power aggregation capacity of the first device reaches the second threshold, the second device reduces the power aggregation capacity of the first device by a specific step. An example is used where the second threshold is 5. In this case, for every five indications the second device receives that indicate it should reduce the power aggregation capacity of the first device, the second device reduces the power aggregation capacity of the first device by one.

[0098] The above provides various methods for adjusting the power aggregation capacity of the first device using a second device. In actual application, the adjustment is not limited to the methods described above. For example, alternatively, a combination of two or three of the status information, indicator information, and indication information may be used to determine whether and how to adjust the power aggregation capacity of the first device.

[0099] In the implementation method, if both the first and second data are data for the first service, the second device may further establish a correspondence between the second power aggregation capacity and the first service's characteristic information based on the first service's characteristic information. The first service's characteristic information includes one or more of the data distribution characteristics of the first service in the frequency domain, or the power distribution corresponding to the data for the first service. For example, after the second device has adjusted the power aggregation capacity of the first device multiple times, all N consecutive feedback messages (where N is an integer greater than or equal to 1) indicate that the operating status of the first device is normal, and the N+1th feedback message indicates that the operating status of the first device is a warning. In this case, the second device may record the power aggregation capacity corresponding to the Nth feedback message (e.g., the second power aggregation capacity), and specifically, it may record the correspondence between the second power aggregation capacity and the first service's characteristic information. When transmitting data for the first service thereafter, the second device, in accordance with the aforementioned solution of this application, obtains the corresponding power aggregation capacity of the first device (i.e., the second power aggregation capacity) based on the characteristic information of the first service, and then transmits the data for the first service by using the second power aggregation capacity, thereby eliminating the need to dynamically adjust the power aggregation capacity of the first device. This can bring about the following advantages: Firstly, power consumption and resource overhead caused by dynamic adjustments are reduced for both the first and second devices; and secondly, the first device can be prevented from having its service life shortened or even damaged due to frequent warnings caused by dynamic adjustments.

[0100] In the aforementioned solution, the power aggregation capacity of the first device is dynamically adjusted based on feedback information from the first device, thereby enabling the appropriate determination of the power aggregation capacity of the first device. This helps to improve the utilization of the transmission power of the first device while ensuring that the first device operates properly.

[0101] Figure 4 is a diagram illustrating an example of power distribution in the case of power aggregation according to an embodiment of the present application. Compared with Figure 2(c), the example in Figure 4 shows the maximum transmission power P for transmitting a signal (or data) on each RE by the first device. max However, 2×P base From 4×P base It has been increased to . Alternatively, it can be understood as a further 3dB increase in power aggregation capacity based on Figure 2(c). Specifically, before adjustment, the power aggregation capacity of the first device (i.e., the first power aggregation capacity) is 3dB, and after adjustment, the power aggregation capacity of the first device (i.e., the second power aggregation capacity) is 6dB.
