[0108] The time domain data may be uplink time domain data received by the radio frequency device through an antenna. For example, the radio frequency device may collect original data of an uplink signal at the entry of an uplink receiving channel.

[0109] In addition, the control device can send instructional information to the radio frequency device in a triggered manner, such as a user command or configuration, so that the radio frequency device can collect time domain data based on the instructional information.

[0110] It should be understood that the radio frequency device collecting time domain data can be understood as the radio frequency device recording time domain data corresponding to at least one collection point at a certain collection frequency. The collection frequency can represent the number of collection points at which the radio frequency device collects time domain data per unit time. In this embodiment of the present application, the collection frequency domain may be represented instead using a collection periodicity, which is the time interval at which the radio frequency device collects time domain data at two adjacent collection points.

[0111] Optionally, the instruction further indicates a collection frequency for collecting the time domain data and / or a number of collection points for collecting the time domain data.

[0112] In a first implementation, the instruction information may include a corresponding resolution for collecting the time domain data. The radio frequency device may determine the collection frequency and / or the number of collection points based on the resolution.

[0113] It should be noted that the radio frequency device can convert the time domain data into frequency domain data and convert at least one collection point for collecting the time domain data into at least one frequency channel number. The resolution can be a frequency interval between two adjacent frequency channel numbers in the at least one frequency channel number. The value of the resolution is related to a value obtained by dividing the collection frequency by the number of collection points.

[0114] For example, the radio frequency device can determine the number of collection points based on the resolution. In this case, the radio frequency device can determine the collection frequency based on the capability information of the radio frequency device (e.g., capability information of collecting data by the hardware of the radio frequency device), and then determine the number of collection points based on the correspondence between the resolution and the number of collection points.

[0115] Alternatively, for example, the radio frequency device may determine the collection frequency based on the resolution. For example, the radio frequency device may support multiple collection frequencies, and the radio frequency device may determine the particular collection frequency to be selected based on the value of the resolution. For example, when the resolution requirement is high, the radio frequency device may select a high collection frequency to collect time domain data. In this case, the radio frequency device may further determine the number of collection points based on the aforementioned relationship between the resolution and the collection frequency.

[0116] Also, the instruction information may explicitly indicate the value of the resolution, or may implicitly indicate the value of the resolution. For example, when the field indicating the resolution in the instruction information is empty, it indicates that a default value is used for the resolution. In another example, when the instruction information indicates a resolution level, the radio frequency device can determine the value of the resolution based on a preset correspondence between the resolution level and the value of the resolution.

[0117] In a second implementation, the instruction information may include information regarding a corresponding collection frequency for collecting the time domain data and / or a number of collection points for collecting the time domain data. Specifically, the control device may explicitly indicate a collection frequency and / or a number of collection points for collecting the time domain data by the radio frequency device.

[0118] For example, the radio frequency device can report capability information of collecting data by the radio frequency device to the control device, and the control device determines a collection frequency for collecting data and / or a number of collection points for collecting time domain data based on the capability information, and instructs the radio frequency device to collect data.

[0119] Thus, the radio frequency device can collect time domain data at at least one collection point based on the indication information.

[0120] Optionally, the indication further indicates a channel to which the time domain data corresponds.

[0121] For example, the instruction information may include information regarding an antenna identifier corresponding to the time domain data, and the radio frequency device may determine the particular channel(s) for which the time domain data should be collected based on the correspondence between the antenna identifier and the channel.

[0122] In another example, the instruction information includes information regarding corresponding channel identifiers for collecting data, and the radio frequency device collects time domain data on one or more channels indicated by the channel identifiers.

[0123] Thus, the radio frequency device can collect time domain data on the channel indicated by the indication information.

[0124] Optionally, the radio frequency device determines frequency domain amplitude information based on the instruction information, where the frequency domain amplitude information includes information about a frequency domain amplitude corresponding to each of the at least one corresponding frequency channel number for collecting the time domain data. The radio frequency device can convert the time domain data to frequency domain data, convert the at least one collection point for collecting the time domain data to at least one frequency channel number, and convert the time domain data corresponding to the at least one collection point to frequency domain data to obtain information about the frequency domain amplitude corresponding to the at least one frequency channel number.

[0125] The information on the frequency domain amplitude may be a frequency domain amplitude corresponding to at least one frequency channel number after the time domain data is converted into frequency domain data. Alternatively, the information on the frequency domain amplitude may be a frequency domain amplitude obtained after processing (e.g., processing such as quantization, correction, etc.) is performed on the converted frequency domain data. In addition, the information on the frequency domain amplitude information may include a value of the frequency domain amplitude corresponding to at least one frequency channel number, or the frequency domain amplitude may be indicated by indicating an index of the frequency domain amplitude corresponding to at least one frequency channel number. This is not specifically limited in the present application.

[0126] The at least one frequency channel number in the frequency domain amplitude information may include all or a portion of a frequency channel number for converting a collection point to a frequency channel number.

[0127] For example, the indication may further indicate that the frequency domain amplitude information includes information regarding the frequency domain amplitude of a frequency channel number corresponding to a particular portion of the collection point, i.e., the indication may further indicate at least one frequency channel number within the frequency domain amplitude information.

[0128] Optionally, the indication further indicates a start frequency and an end frequency of at least one frequency channel number.

[0129] It should be understood that when the instruction information does not indicate the start frequency, the radio frequency device can default to the start frequency as a default value.Similarly, when the instruction information does not indicate the end frequency, the radio frequency device can default to the end frequency as a default value.

[0130] The frequency domain amplitude information may include information regarding frequency domain amplitudes corresponding to frequency channel numbers between a start frequency and an end frequency.

[0131] In this manner, the radio frequency device can determine frequency domain amplitude information based on the instruction information, or determine, based on the instruction information, the frequency domain amplitude of a particular frequency channel number(s) that needs to be transmitted to the control device.

[0132] Optionally, the instruction information further instructs the radio frequency device to split the time domain data into a number of data packets that are transmitted periodically.

[0133] Furthermore, when transmitting the time domain data to the control device, the radio frequency device can divide the time domain data into multiple data packets, and for each data packet, the time domain data is transmitted to the control device with a time periodicity at a regular interval.

[0134] Optionally, the indication information further indicates a data amount of the data packet and / or the indication information further indicates a transmission periodicity of the multiple data packets.

[0135] For example, the control device can determine the data amount and / or transmission periodicity of each data packet based on the data transfer capability of the control device, and indicate the data amount and / or periodicity based on the indication information. The radio frequency device uploads the time domain data in the form of packets based on the data amount and / or periodicity. The periodicity may be a time interval between successively transmitted data packets.

[0136] In this way, the radio frequency device can upload the time domain data in the form of packets based on the instruction information, thereby improving the reliability of data transmission.

[0137] In a possible implementation, when determining the frequency domain amplitude information, the radio frequency device can perform gain compensation on the frequency domain data converted from the time domain data. In this case, the method further includes step S202 described below.

[0138] Optional S202: The radio frequency device determines frequency domain amplitude information based on the indication information and the gain compensation information.

[0139] The gain compensation information includes at least one of the following information: a gain compensation corresponding to each of the at least one frequency channel number, and an average gain compensation corresponding to the time domain data.

[0140] For the gain compensation corresponding to the frequency channel number, the radio frequency device can perform gain compensation for each frequency channel number based on the characteristics of each frequency channel number. For example, the radio frequency device stores gain compensation information corresponding to each frequency channel number, and the gain compensation information corresponding to each frequency channel number is related to the hardware characteristics corresponding to each frequency channel number. For example, due to the limitation of the hardware manufacturing process, the radio frequency device may have different gain compensation for different frequency channel numbers. In order to ensure that the accuracy of the frequency domain amplitude of each frequency channel number is consistent, the radio frequency device can obtain the gain compensation of each frequency channel number during equipment testing and form the gain compensation information.

[0141] For the average gain compensation corresponding to the time domain data, the radio frequency device can perform average gain compensation for all frequency channel numbers based on the environmental characteristics present when the time domain data is collected. For example, different temperatures and humidity may correspond to different average gain compensations. The radio frequency device can monitor the environmental characteristics in real time and determine the average gain compensation based on the environmental characteristics. Thus, if the environmental characteristics change when the time domain data is collected, the average gain compensation changes accordingly.

[0142] Therefore, the radio frequency device can perform gain compensation when the frequency domain amplitude information is generated based on hardware or environmental factors to improve the accuracy of information transmission.

[0143] S203: The radio frequency device transmits frequency domain amplitude information to the control device, and in response, the control device receives frequency domain amplitude information from the radio frequency device.

[0144] The frequency domain amplitude information includes information regarding frequency domain amplitudes corresponding to each of at least one corresponding frequency channel number for collecting time domain data.

[0145] The radio frequency device may determine frequency domain amplitude information and transmit the frequency domain amplitude information to the controller over a fronthaul interface between the radio frequency device and the controller.

[0146] The frequency domain amplitude information may be a list. For example, the list includes a frequency channel number, a frequency domain amplitude, and a correspondence between the frequency channel number and the frequency domain amplitude. The frequency domain amplitude information may also include an ordered frequency domain amplitude. For example, the frequency domain amplitude is ordered from a start frequency to an end frequency, and the control device can determine the correspondence between the frequency channel number and the frequency domain amplitude based on the order.

[0147] The frequency domain amplitude information can be used to determine whether interference is present.

[0148] For example, the control device can display a frequency channel number and a frequency domain amplitude of the frequency channel number in real time based on the frequency domain amplitude information, and indicate whether interference exists depending on whether an anomaly exists in the presented frequency domain amplitude.

[0149] Optionally, the controller creates a spectral map based on the frequency domain amplitude information, the spectral map indicating whether interference is present.

[0150] For clarity, the frequency domain amplitude information will be described using an example with reference to FIG. 3. Please refer to FIG. 3. The control device receives the frequency domain amplitude information and creates a spectrum diagram shown in FIG. 3. The horizontal coordinate is the frequency channel number corresponding to the collection point. The vertical coordinate is the frequency domain amplitude corresponding to each frequency channel number. The control device indicates whether interference exists according to whether there is a peak on the spectrum diagram, whether there is abnormal fluctuation, whether there are parameters that are not within the range of normal values ​​(e.g., frequency domain amplitude, difference between frequency domain amplitudes of different frequency channel numbers, and increase in frequency domain amplitude).

[0151] The frequency domain amplitude information may further be used to determine the type of interference.

[0152] For example, the frequency domain amplitude information may indicate the presence of narrowband interference if a peak appears in the spectrogram corresponding to the frequency domain amplitude information.

[0153] Thus, frequency domain amplitude information received by the controller can be used to assist in determining whether and what type of interference is present, thereby improving communications reliability.

[0154] Optionally, the frequency domain amplitude information further indicates a channel that corresponds to the time domain data, For example, the frequency domain amplitude information may include an antenna identifier or a channel identifier that corresponds to the time domain data.

[0155] Therefore, the radio frequency device can collect time domain data according to the instruction information, convert the collected time domain data into frequency domain data to generate frequency domain amplitude information, and send the frequency domain amplitude information to the control device. In this way, interference detection can be performed and communication efficiency can be improved.

[0156] In a possible implementation, the radio frequency device can transmit the time domain data to the control device in the form of a packet. In this case, the method 200 further includes step S204, which will be described below.

[0157] Optional S204: The radio frequency device transmits time domain data to the control device, and in response, the control device receives the time domain data from the radio frequency device.

[0158] The radio frequency device can transmit the time domain data to the controller through a fronthaul interface between the radio frequency device and the controller.

[0159] When the instruction information further instructs the radio frequency device to divide the time domain data into a plurality of data packets that are periodically transmitted, the radio frequency device can divide the time domain data into a plurality of data packets according to the instruction information, and periodically transmit the plurality of data packets to the control information. For example, the radio frequency device can know that the time domain data needs to be uploaded in the form of packets according to the instruction information, and the radio frequency device can further determine the periodicity with which the plurality of data packets are periodically transmitted and the data amount of the data packets.

[0160] When the instruction information further indicates the periodicity and / or the data amount of the data packets, the radio frequency device uploads the time domain data in the form of packets based on the data amount and / or the periodicity. For example, the radio frequency device assembles the 1024-bit data into data packets in time order based on the instruction, and transmits the data packets in sequence at intervals of 50 milliseconds.

[0161] Therefore, in this embodiment of the present application, the radio frequency device can collect time domain data according to the instruction information, convert the time domain data obtained by collecting the time domain data into frequency domain data to generate frequency domain amplitude information, and send the frequency domain amplitude information to the control device. In this way, interference detection can be performed and communication efficiency can be improved.

[0162] FIG. 4 is a schematic flow chart of an information transmission method 400 according to an embodiment of the present application.

[0163] S401: The control device transmits instruction information to the radio frequency device, and in response, the radio frequency device receives instruction information from the control device.

[0164] The instruction information instructs the radio frequency device to collect time domain data, in other words, the instruction information instructs the radio frequency device to initiate a spectrum scan on the time domain data.

[0165] The manner in which the instruction information instructs the radio frequency device to collect time domain data is similar to that described in method 200. For simplicity, the details will not be repeated here.

[0166] Optionally, the instruction information further indicates a collection frequency for collecting the time domain data and / or a number of collection points for collecting the time domain data. The manner in which the instruction information indicates the collection frequency and / or the number of collection points is similar to that described in method 200. For simplicity, the details will not be repeated here.

[0167] Optionally, the indication information further indicates a channel corresponding to the time domain data. The manner in which the indication information indicates the channel is similar to the manner described in the method 200. For simplicity, the details are not repeated here.

[0168] Optionally, the indication information may further instruct the radio frequency device to divide the time domain data into multiple data packets to be periodically transmitted. The manner in which the indication information indicates the multiple data packets to be periodically transmitted is similar to that described in the method 200. For simplicity, the details are not repeated here.

[0169] Optionally, the indication information can further indicate a transmission periodicity of the plurality of data packets, and / or the indication information can further indicate a data amount of the data packets. The manner in which the indication information indicates the periodicity and / or the data amount is similar to the manner described in the method 200. For simplicity, the details are not repeated here.

[0170] S402: The radio frequency device transmits time domain data information to the control device, and correspondingly, the control device receives the time domain data information from the radio frequency device.

[0171] The time domain data information includes time domain data used to determine a frequency domain amplitude corresponding to at least one frequency channel number.

[0172] Optionally, the time domain data information further includes at least one of the following: a frequency for collecting the time domain data, a start frequency for collecting the time domain data, an end frequency for collecting the time domain data, a data format of the time domain data, a channel identifier corresponding to the time domain data, and an antenna identifier corresponding to the time domain data.

[0173] The frequency for collecting the time domain data, the start frequency for collecting the time domain data, and the end frequency for collecting the time domain data may be used to determine the frequency channel number corresponding to the collection point. For example, the control device may determine the frequency channel number based on the frequency, start frequency, or end frequency during the process of converting the time domain data to frequency domain data. It should be understood that when the time domain data information does not include the frequency, start frequency, or end frequency, the control device may use an agreed-upon value of the frequency, start frequency, or end frequency.

[0174] The frequency for collecting time domain data is time domain information, and the start frequency and end frequency are frequency domain information. When collecting time domain data, the radio frequency device can determine the start frequency and end frequency of the frequency channel number corresponding to the collection point according to the collection point.

[0175] The data format of the time domain data may be a bit length and a synthesis manner of the time domain data. For example, when the time domain data is IQ data, the time domain data information may indicate a synthesis manner of the I component and the Q component of the time domain data and the number of bits occupied by each of the I component and the Q component, so that the control device can analyze the time domain data according to the data format to obtain the frequency domain amplitude.

[0176] The channel identifier corresponding to the time domain data and the antenna identifier corresponding to the time domain data may indicate the particular channel(s) from which the radio frequency device collects the time domain data.

[0177] Thus, the radio frequency device collects time domain data, determines time domain data information, and transmits the time domain data information to the controller, which determines a frequency domain amplitude based on the time domain data information.

[0178] The frequency domain amplitude of the at least one frequency channel number may be used to determine whether interference exists. The manner of determining whether interference exists based on the frequency domain amplitude of the at least one frequency channel number is similar to the manner described in method 200. For simplicity, the details will not be repeated here.

[0179] The frequency domain amplitude of the at least one frequency channel number may be further used to determine the type of interference. The manner in which the frequency domain amplitude of the at least one frequency channel number is used to determine the type of interference is similar to the manner described in method 200. For simplicity, the details will not be repeated here.

[0180] In a possible manner, the control device can perform gain compensation when determining the frequency domain amplitude of the at least one frequency channel number. In this case, the method further includes step S403.

[0181] S403: The radio frequency device sends gain compensation information to the control device, and the control device correspondingly receives gain compensation information from the radio frequency device.

[0182] The gain compensation information is used to determine the frequency domain amplitude. The gain compensation information may include at least one of the following information: a gain compensation corresponding to each of the at least one frequency channel number, and an average gain compensation corresponding to the time domain data. In this case, the control device determines the frequency domain amplitude based on the time domain data information and the gain compensation information.

[0183] The description of the gain compensation information is similar to that of the gain compensation information in step S203 of method 200. For simplicity, the details will not be repeated here.

[0184] Optionally, the gain compensation information includes an antenna identifier or a channel identifier. Further, the control device can select gain compensation information of a channel corresponding to the time domain data from the gain compensation information to perform gain compensation.

[0185] It should be appreciated that the radio frequency device can split the gain compensation information into multiple pieces of information for transmission. For example, when the average gain compensation changes with the environment for collecting the time domain data, the radio frequency device can transmit the gain compensation information together with the time domain data information, including the corresponding average gain compensation generated when the time domain data is collected this time.

[0186] Therefore, the control device can perform gain compensation when determining the frequency domain amplitude based on the received gain compensation information, thereby improving the reliability of information transmission.

[0187] Therefore, in this embodiment of the present application, the radio frequency device can collect time domain data according to the instruction information sent by the control device to generate time domain data information, and send the time domain data information to the control device. The control device can determine the frequency domain amplitude according to the time domain data information. In this way, interference detection can be implemented and communication efficiency is improved.

[0188] It should be understood that in all the embodiments of the present application, information such as instruction information, frequency domain amplitude information, gain compensation information, and time domain data information may all be divided into multiple pieces of information for transmission, which is not specifically limited in the present application.
