Description

[Technical Field]

[0001] This application claims priority to Chinese Patent Application No. 202111669147.6, entitled "Data Transmission Method, Radio Frequency Device, and Control Device," filed with the State Intellectual Property Office of the People's Republic of China on December 31, 2021, which is incorporated herein by reference in its entirety.

[0002] The present application relates to the field of communications technology, and more particularly to a data transmission method, a radio frequency device, and a control device. [Background technology]

[0003] Currently, two different baseband application standards can share a carrier. For example, new radio (NR) and long term evolution (LTE) can share spectrum resources. NR and LTE can report their respective channel configuration information to a resource allocation node. The resource allocation node can configure resource blocks (RBs) and power based on the channel configuration information of the two standards. Furthermore, the baseband processing unit corresponding to NR and the baseband processing unit corresponding to LTE can schedule the configured RBs and configured power separately.

[0004] However, when two standards share power, they must transmit data based on a configured constant transmission power and cannot increase the power. If the power of one of the two standards is increased, the baseband processing unit of one of the two standards cannot detect whether the power of the other standard has been increased, which may cause the total power of the two standards to exceed the power usage range. This affects the operation and overall performance of the hardware.

[0005] Therefore, there is an urgent need for a data transmission method, a radio frequency device, and a control device to increase the flexibility of data transmission through the system. Summary of the Invention

[0006] The present application provides a data transmission method, a radio frequency device, and a control device to increase the flexibility of data transmission through a system. [Means for solving the problem]

[0007] According to a first aspect, a data transmission method is provided. The method may be performed by a radio frequency device or by a chip in the radio frequency device. The method includes a step of the radio frequency device obtaining a transmission power. The transmission power is determined based on first power increase information and second power increase information.

The second power increase information indicates a second power increase amplitude corresponding to a second standard in a time unit. The radio frequency device transmits data corresponding to the time unit based on the transmission power. The first standard and the second standard are different baseband operating standards.

[0008] Therefore, in the present application, the radio frequency device obtains a transmission power determined based on both the first power increase information and the second power increase information, and can increase the power even in a scenario where two standards share power, thereby improving the flexibility of data transmission by the system.

The total power spectrum is determined based on the total power information. The total power spectrum indicates a correspondence relationship between frequency and power in a time unit.

The 5G mobile communication system in this application includes a non-standalone (NSA) 5G mobile communication system or a standalone (SA) 5G mobile communication system. Alternatively, the communication system may be a public land mobile network (PLMN), a device-to-device (D2D) communication system, a machine-to-machine (M2M) communication system, an Internet of things (IoT) communication system, a vehicle-to-everything (V2X) communication system, an unmanned aerial vehicle (UAV) communication system, or another communication system.

[0071] In addition, the network architectures and service scenarios described in the embodiments of the present application are intended to more clearly explain the technical solutions of the embodiments of the present application, and do not limit the technical solutions provided in the embodiments of the present application. Those skilled in the art can know that as network architectures evolve and new service scenarios emerge, the technical solutions provided in the embodiments of the present application can also be applied to similar technical problems.

[0072] To facilitate understanding of the embodiments of the present application, the application scenario of the embodiments of the present application will be described in detail first with reference to FIG.

[0073] 1 is a schematic diagram of the structure of a communication system to which an embodiment of the present application can be applied. First, a description will be given of devices that can be used in this communication system.

[0074] 1. Radio Unit (RU) 110: The RU 110 can perform functions such as performing intermediate frequency processing, radio frequency processing, duplexing, etc. on signals. For example, the RU 110 can be a remote radio unit (RRU), an active antenna unit (AAU), or another network element or communication device capable of processing intermediate frequency signals, radio frequency signals, or intermediate radio frequency signals. In some communication systems, for example, in communication systems using the enhanced common public radio interface (eCPRI), the RU 110 can further have some baseband processing functions, which is not specifically limited in this application.

[0075] In this embodiment of the present application, the RU 110 may further include a multimode-multiband architecture radio platform (MARP), which can perform intermediate frequency processing and radio frequency processing on the signals.

[0076] 2. Baseband unit (BU) 120: The BU 120 can perform baseband signal processing functions. For example, the BU 120 can be a baseband unit (BBU), a central control unit (CU), a distributed control unit (DU), or another network element or communication device with baseband signal processing capabilities.

[0077] In this embodiment of the present application, the BU 120 can support multiple baseband application standards. For example, the BU 120 can support both the NR standard and the LTE standard. In this case, the BU 120 can include a first control unit and a second control unit. The first control unit can solely perform baseband processing for the NR standard. The second control unit can solely perform baseband processing for the LTE standard.

[0078] The first control device for baseband processing in the NR standard may include a physical layer (sometimes referred to as layer 1 (L1)), a data link layer (sometimes referred to as L2), and a network layer (sometimes referred to as L3). L1 may perform functions such as resource block matching, compression, encryption, data encoding and decoding, modulation and demodulation, and checking. L2 may include an RLC layer and a MAC layer, and may perform resource scheduling, allocate data to each resource block, and perform data identification and assembly. L3 may include an RRC layer and a NAS layer, and may perform resource allocation and management.

[0079] Correspondingly, the second control device for baseband processing of the LTE standard also includes L1, L2, and L3, and can perform related baseband processing in the LTE standard.

[0080] The BU 120 and the RU 110 may be connected using optical fibers. The communication interface between the BU 120 and the RU 110 may be referred to as a fronthaul interface. For example, the fronthaul interface may be a common public radio interface (CPRI), an eCPRI interface, or another interface for connecting the BU 120 and the RU 110 that will be defined in the future. This is not specifically limited in this application.

[0081] In this embodiment of the present application, when the BU 120 includes a first controller for baseband processing of the NR standard and a second controller for baseband processing of the LTE standard, the first controller and the second controller can communicate with the RU 110 separately. For example, the first controller and the second controller may each be connected to the RU 110 using a communication optical fiber, or the first controller and the second controller may be connected to the RU 110 by sharing a communication optical fiber. When the first controller and the second controller communicate with the RU 110 using a shared optical fiber, the first controller and the second controller may be connected to the same node and communicate with the RU 110 through the node. Alternatively, a communication link may be established between the first controller and the second controller. The first controller transmits information related to the NR standard to the second controller, and the second controller transmits information related to the NR standard and information related to the LTE standard to the RU 110, or vice versa.

[0082] The NR standard and the LTE standard can share frequency resources and power. For example, some frequencies on one symbol are used for data transmission in the NR standard, and some frequencies are used for data transmission in the LTE standard. The LTE standard and the NR standard share frequency resources corresponding to symbols and also share the power configured for the symbols. The frequency resources corresponding to one symbol may be divided at the granularity of resource elements (REs). One RE is one subcarrier in the frequency domain. The frequency resources corresponding to one symbol may include at least one subcarrier or RE. Alternatively, the frequency resources corresponding to one symbol may be divided at the granularity of RBs. One RB includes 12 subcarriers in the frequency domain. The frequency resources corresponding to one symbol may include at least one RB. This is not specifically limited in this application. For clarity, the following uses an example in which the frequency resources corresponding to one symbol are divided at the granularity of REs or subcarriers.

[0083] In this embodiment of the present application, the symbols are also referred to as time-domain symbols, and in particular may be orthogonal frequency division multiplexing (OFDM) symbols, Discrete Fourier Transform-spread-OFDM (DFT-s-OFDM) symbols, or other time-domain symbols defined in future communications.

[0084] FIG. 2 is a schematic diagram showing how the NR standard and the LTE standard share RBs. See FIG. 2. One RB includes 12 subcarriers in the frequency domain, and the BU can allocate resources occupied by the NR standard and resources occupied by the LTE standard at a granularity of resource elements (REs). One RE is one subcarrier in the frequency domain and one symbol in the time domain. It can be seen that, on one symbol, some subcarriers can be used for data transmission according to the NR standard and some subcarriers can be used for data transmission according to the LTE standard. Correspondingly, the power configured for one symbol is used for both data transmission according to the NR standard and data transmission according to the LTE standard.

[0085] FIG. 3 is a schematic diagram of power sharing between the LTE standard and the NR standard. See (a) of FIG. 3. For example, a total power of 40 W is configured for one RB. The available power specification configured for the LTE standard is 20 W, and the available power specification configured for the NR standard is 20 W. In this case, compared to a single-standard system, the power allocation for each of the two standards is reduced by half in this system, and there may be unused power for both standards, resulting in a serious waste of power specifications.

[0086] See (b) of Figure 3. For example, a total power of 40 W is configured for one RB. When allocating resources occupied by the NR standard and the LTE standard at the granularity of the RE, the BU can allocate power based on the occupied resources. For example, in an RB, the NR standard can use 30 W of power, and the LTE standard can use 10 W of power. In this case, the available power specification configured for the LTE standard is 40 W, and the available power specification configured for the NR standard is also 40 W. This reduces waste of power specifications. However, in this case, when 30 W of power is scheduled in the NR standard, power can be transmitted only based on the fixed parameters of the channel corresponding to each RE, and when 10 W of power is scheduled in the LTE standard, power can be transmitted only based on the fixed parameters of the channel corresponding to each RE. The power of the channel cannot be increased in the NR standard or the LTE standard. Otherwise, the total power of the two standards may exceed 40 W, which will affect the operation and overall performance of the hardware.

[0087] Therefore, the present application provides a data transmission method to improve the flexibility of data transmission by the system.

[0088] FIG. 4 is a schematic flowchart of a data transmission method 400 according to an embodiment of the present application.

[0089] S410: The radio frequency device obtains transmission power.

[0090] The transmit power is determined based on first power increase information and second power increase information, where the first power increase information indicates a first power increase amplitude corresponding to the first standard in the time unit, and the second power increase information indicates a second power increase amplitude corresponding to the second standard in the time unit.

[0091] The first and second standards are two different baseband operating standards. For example, the first standard is an NR standard and the second standard is an LTE standard. Alternatively, the first standard is an LTE standard and the second standard is an NR standard.

[0092] The transmission power is the transmission power shared by the first standard and the second standard. In other words, the data transmitted by the radio frequency device using the transmission power includes data of the first standard and data of the second standard.

[0093] The radio frequency device can obtain transmission power in the following three ways, which will be described separately below.

[0094] Method 1 Step S410 includes steps S4101 to S4103.

[0095] S4101: The first control device sends first power increase information to the radio frequency device. Correspondingly, the radio frequency device receives the first power increase information from the first control device.

[0096] The first power increase information indicates a first power increase amplitude corresponding to a first standard in time units.

[0097] Optionally, the time unit is a symbol.

[0098] The first power increase amplitude may indicate a power increase factor of the symbol. The power increase factor may be expressed in decibels (where 1 dB=101g(A / B), where A / B represents the factor). The first power increase information may include the symbol and the power increase decibel.

[0099] Note that the power increase factor of a symbol is the factor by which the power of the symbol is increased compared to the constituent powers of the symbol.

[0100] Optionally, the first control device transmits a power configuration parameter of the first standard to the radio frequency device, the power configuration parameter indicating a configured power of each of the plurality of symbols.

[0101] The constituent power of a symbol can be represented by a constituent power spectrum configured by the first control device for each symbol during power allocation. The constituent power spectrum describes the correspondence between frequency and power. For example, the constituent power spectrum can indicate the power for transmitting data on each subcarrier in one symbol. In this case, the constituent power of a symbol is the total power of the constituent power spectrum. For example, the constituent power spectrum indicates that the power for transmitting data on subcarrier #1, subcarrier #2, and subcarrier #3 in symbol #1 is 1 W, 1 W, and 2 W, respectively. In this case, the total power of the constituent power spectrum is 4 W, and the constituent power corresponding to the first standard of symbol #1 is 4 W. In addition, if the first power increase amplitude indicates that the power corresponding to the first standard of symbol #1 is increased by 3 dB (the multiple is approximately equal to 1), the resulting power after the increase corresponding to the first standard of symbol #1 is 8 W. The power spectrum obtained after the increase corresponding to the first standard for symbol #1 indicates that the power for transmitting data on subcarrier #1, subcarrier #2, and subcarrier #3 is 2W, 2W, and 4W, respectively.

[0102] It should be understood that if the first power increase amplitude indicates that the power increase multiple of the symbol is 0, it means that the power corresponding to the first standard of symbol #1 is not increased and the data is still transmitted based on the configured power.

[0103] S4102: The second control device transmits second power increase information to the radio frequency device. Correspondingly, the radio frequency device receives the second power increase information from the second control device.

[0104] The second power increase information indicates a second power increase amplitude corresponding to a second standard in time units.

[0105] The description of the second power increase information is similar to that of the first power increase information, and for the sake of brevity, the details will not be described again here.

[0106] S4103: The radio frequency device determines a transmission power based on total power information. The total power information is determined based on a first power increase amplitude and a second power increase amplitude. The total power information is for determining a total power spectrum. The total power spectrum indicates a correspondence relationship between frequency and power in a time unit.

[0107] The radio frequency device can determine total power information based on the first power increase amplitude and the second power increase amplitude. The total power information can have two forms. The first form is as follows: the total power information describes the power increase amplitude at each frequency in a time unit, and the radio frequency device can determine the power obtained after the increase at each frequency based on the power configuration parameters for the time unit to form the total power spectrum. The second form is as follows: the total power information directly describes the power obtained after the increase at each frequency in a time unit to form the total power spectrum.

[0108] For example, the radio frequency device may determine a power boost amplitude corresponding to a first standard for symbol #1 based on the first boost information, and determine a power boost amplitude corresponding to a second standard for symbol #1 based on the second boost information. Furthermore, the radio frequency device may determine the power obtained after boosting on each subcarrier in symbol #1 based on the power configuration parameters of the first standard and the power configuration parameters of the second standard to form a total power spectrum.

[0109] By way of example and not limitation, symbol #1 includes 12 subcarriers (subcarrier #1 to subcarrier #12). Subcarrier #1 to subcarrier #6 are configured for data transmission according to a first standard. Subcarrier #7 to subcarrier #12 are configured for data transmission according to a second standard. The configured power on subcarrier #1 to subcarrier #12 is all 1 W. The first power increase information indicates that the power corresponding to the first standard of symbol #1 is increased by 1. In this case, the increased power by 1 on subcarrier #1 to subcarrier #6 is all 2 W. The second power increase information indicates that the power corresponding to the second standard of symbol #1 is increased by 0.5. In this case, the increased power by 0.5 on subcarrier #7 to subcarrier #12 is all 1.5 W. For ease of explanation, please refer to FIG. 5, which shows a total power spectrum corresponding to an example. The horizontal coordinate represents frequency. In this example, 12 subcarriers are used to represent frequency, and the vertical coordinate represents the power of each subcarrier.

[0110] It should be understood that the above is only an example in which the frequency domain corresponding to symbol #1 includes 12 subcarriers (one RB). In this embodiment of the present application, the total power spectrum should include the correspondence between power and all frequency bands supported by symbol #1. For example, if the frequency resource corresponding to one symbol is divided into RB granularity, the power spectrum can describe the power corresponding to each RB of the symbol.

[0111] The radio frequency device can finally determine the transmission power for transmitting data based on the total power spectrum and the data transmission capability of the radio frequency device.

[0112] Optionally, if the total power of the total power spectrum is greater than or equal to a first threshold and the spectral density of the total power spectrum is greater than or equal to a second threshold, the radio frequency device determines the transmit power by performing a clipping operation on the total power spectrum.

[0113] In other words, if the total power spectrum indicates that the power obtained after the increase exceeds the data transmission capability range of the radio frequency device, the radio frequency device performs a clipping process on the total power spectrum so that the sum of the powers of the two standards falls within the data transmission capability range of the radio frequency device. If the total power spectrum satisfies two conditions, it can be considered that the power obtained after the increase exceeds the data transmission capability range of the radio frequency device. The two conditions will be described separately below.

[0114] Condition 1: The total power of the total power spectrum is equal to or greater than a first threshold.

[0115] The total power is the sum of the powers corresponding to all frequencies in a time unit. For example, in Figure 5, the total power is the area of ​​the total spectrum graph, and subcarriers are used to represent frequencies. Thus, the total power obtained after increasing by 12 subcarriers is 21 W. The value of the first threshold is related to the transmission capacity of the data transmission by the radio frequency device. For example, the first threshold may be the rated transmission power for transmitting data by the radio frequency device. If the total power is greater than the first threshold, it means that the rated transmission power of the radio frequency device is fully used.

[0116] Condition 2: The spectral density of the total power spectrum is equal to or greater than a second threshold.

[0117] The spectral density is the average power of the power corresponding to all frequencies in a time unit. For example, in FIG. 5, the spectral density is the average power of 12 subcarriers: 2 1 / 12 = 1.75 W. The value of the second threshold also relates to the transmission capacity of data transmission by the radio frequency device. In one possible implementation, the value of the second threshold may be a value obtained by increasing the spectral density of the constituent power spectrum corresponding to the configuration parameters by 1.8 dB. In this case, condition 2 can be equivalently replaced with the decibel increase by which the spectral density of the total power spectrum is increased compared to the spectral density of the constituent power spectrum being 1.8 dB or more. For example, in FIG. 5, the constituent power on the 12 subcarriers without an increase is 1 W, i.e., the spectral density of the constituent power spectrum is 1 W. The decibel increase by which the spectral density of the total power spectrum is increased compared to the spectral density of the constituent power spectrum is 101 g (0.75), which is approximately equal to 1.2 dB and less than 1.8 dB.

[0118] If the total power spectrum meets the above two conditions, the radio frequency device needs to perform clipping processing on the total power spectrum.

[0119] The clipping process may be an overall reduction of the transmission power of the symbols or another power reduction scheme that may allow at least one of the conditions to not be met.

[0120] It should be noted that if the first power increase information indicates that the increased power corresponding to the first standard in the time unit is 0, and the second power increase information indicates that the increased power corresponding to the second standard in the time unit is also 0, the radio frequency device can assume by default that the combined power of the two standards does not exceed the capability range in this case, and the radio frequency device does not need to make a decision on the aforementioned two conditions. Otherwise, the radio frequency device needs to determine whether the total power spectrum satisfies the aforementioned two conditions based on the first increase information and the second increase information.

[0121] Therefore, in Scheme 1, the first control device and the second control device can separately transmit their respective power increase information to the radio frequency device. After receiving the two pieces of power increase information, the radio frequency device combines the two pieces of power increase information, and further determines the final transmission power for transmitting data based on the total power information obtained after the combination of the two standards and the transmission capability of the radio frequency device, so that the power can be increased even in a scenario where the two standards share power, and the flexibility of data transmission by the system is improved.

[0122] Method 2 Step S410 includes steps S4104 to S4107.

[0123] S4104: The second control device sends second power increase information to the first control device. Correspondingly, the first control device receives second power increase information from the second control device.

[0124] For example, a first controller and a second controller can establish a communication link, and the second controller transmits second incremental information to the first controller over the communication link.

[0125] S4105: The first control device determines the total power information.

[0126] The first controller determines total power information based on the first power increase information and the second power increase information received from the second controller.

[0127] The descriptions of the first power increase information, the second power increase information, and the total power information are the same as those in the above-mentioned Scheme 1. For the sake of brevity, the details will not be described again here. It should be noted that when the total power information directly describes the power obtained after the increase at each frequency in a time unit, the second control device can further send power configuration parameters corresponding to the second standard to the first control device.

[0128] S4106: The first control device transmits the total power information to the radio frequency device. Correspondingly, the radio frequency device receives the total power information from the first control device.

[0129] S4107: The radio frequency device determines a transmission power based on the total power information.

[0130] The description of the radio frequency device determining the transmission power based on the total power information is the same as that of Scheme 1 above, and for the sake of brevity, the details will not be described again here.

[0131] It should be understood that the above is an example in which the first control device determines the total power information. Conversely, the same applies to the case in which the first control device sends the first power increase information to the second control device, and the second control device determines the total power information and sends the total power information to the radio frequency device. Details will not be described again.

[0132] Therefore, in Scheme 2, the first control device or the second control device can combine the first power increase information and the second power increase information to generate total power information, and transmit the total power information to the radio frequency device. Furthermore, the radio frequency device finally determines the transmission power for transmitting data based on the total power information obtained after the combination of the two standards and the transmission capability of the radio frequency device, so that the power can be increased even in a scenario where the two standards share power, thereby improving the flexibility of data transmission by the system.

[0133] Method 3 Step S410 includes steps S4108 to S4110.

[0134] S4108: The second control device sends second power increase information to the first control device. Correspondingly, the first control device receives second power increase information from the second control device.

[0135] For this step, see also step S4104 above, and for the sake of brevity, the details will not be repeated here.

[0136] S4109: The first control device determines the transmission power.

[0137] The first control device can obtain capability information for data transmission by the radio frequency device. Furthermore, the first control device determines total power information based on the first power increase information and the second power increase information, and determines transmission power based on the total power information. The manner in which the first control device determines transmission power based on the total power information is similar to the manner in which the radio frequency device determines transmission power based on the total power information. For brevity, the details will not be described again here.

[0138] S4110: The first control device transmits transmission power to the radio frequency device. Correspondingly, the radio frequency device receives transmission power from the first control device.

[0139] The first control device may transmit the transmission power to the radio frequency device by transmitting the total power information and the clipping policy, or the first control device may directly transmit the transmission power to the radio frequency device. This is not specifically limited in the present application. The above description of the first control device determining the transmission power is similar to the description of the second control device determining the transmission power. The details will not be described again.

[0140] Therefore, in method 3, the first control device or the second control device obtains capability information for data transmission by the radio frequency device, generates total power information based on the first power increase information and the second power increase information, and determines the transmission power for transmitting data by the radio frequency device based on the total power information, so that the power can be increased even in a scenario where two standards share power, and the flexibility of data transmission by the system is improved.

[0141] The above describes how a radio frequency device obtains transmission power.

[0142] S420: The radio frequency device transmits data corresponding to the time unit based on the transmission power.

[0143] In other words, the radio frequency device uses transmission power to transmit data corresponding to a time unit.

[0144] The data corresponding to the time unit may be the sum of the data corresponding to the first standard in the time unit and the data corresponding to the second standard in the time unit.

[0145] For example, the radio frequency device transmits data corresponding to a first standard in symbol #1 and data corresponding to a second standard in symbol #1 based on the transmission power, i.e., the first standard and the second standard share the transmission power in symbol #1.

[0146] Therefore, in this embodiment of the present application, the radio frequency device obtains a transmission power determined based on both the first power increase information and the second power increase information, and can increase the power even in a scenario where two standards share power, thereby improving the flexibility of data transmission by the system.

[0154] Therefore, in this embodiment of the present application, the radio frequency device obtains a transmission power determined based on both the first power increase information and the second power increase information, and can increase the power even in a scenario where two standards share power, thereby improving the flexibility of data transmission by the system.
