For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0068] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0069] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0070] The embodiments of the present application provide a data processing method, a base station, an apparatus, an electronic device and a storage medium, which are used to solve the technical problem of large amount of data processed within the base station in the related art.

[0071] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0072] Figure 1 It is a flowchart of a data processing method according to an embodiment of the present application.

[0073] like Figure 1 As shown, the data processing method of the embodiment of the present application includes:

[0074] S101: Receive original data sent by a terminal through a first number of antennas in an antenna unit.

[0075] It should be noted that the data processing method of the embodiment of the present application is executed by a base station. In one implementation, the execution entity is an active antenna processing unit (AAU) in the base station.

[0076] In the embodiment of the present application, the base station has an antenna unit, and the antenna unit includes a first number of antennas. It should be noted that there are no excessive restrictions on the type and first number of antenna units. For example, the antenna unit may adopt a dual-polarization mode, and the first number may be 64.

[0077] In an embodiment of the present application, original data sent by the terminal may be received by a first number of antennas in the antenna unit.

[0078] In one embodiment, the original data includes transmission data of at least one uplink channel. It should be noted that there is no excessive limitation on the type of uplink channel. For example, uplink channels include but are not limited to physical random access channel (PRACH), physical uplink shared channel (PUSCH), and physical uplink control channel (PUCCH).

[0079] S102, converting the original data to obtain target data, wherein the number of antennas corresponding to the target data is a second number, and the second number is less than or equal to the first number.

[0080] In an embodiment of the present application, the original data may be converted to obtain target data, wherein the number of antennas corresponding to the target data is a second number, and the second number is less than or equal to the first number. It should be noted that there are no excessive restrictions on the conversion strategy and the second number. For example, the first number may be 64 and the second number may be 8.

[0081] In the embodiments of the present disclosure, the amount of data processed inside the base station is positively correlated with the number of antennas, wherein the type of data processing is not overly limited, for example, data processing includes data transmission between the AAU and the BBU, data detection, etc. In the related art, the number of antennas is the first number, the amount of data processed inside the base station is large, the data processing consumes a lot of resources, and the required cost is high. In this method, the original data can be converted to obtain the target data, and the number of antennas corresponding to the target data is less than or equal to the first number, that is, the number of antennas for the data can be reduced by data conversion, thereby greatly reducing the amount of data processed inside the base station.

[0082] For example, the first number may be 64, and the second number may be 8, and the amount of data processed within the base station in this method may be reduced to 1 / 8 of that in the prior art.

[0083] In one embodiment, the original data includes transmission data of at least one uplink channel. It is understandable that the transmission data of each uplink channel can be converted respectively to obtain the target data of each uplink channel. The transmission data of each uplink channel can correspond to the same conversion strategy or different conversion strategies. Different uplink channels can correspond to different second quantities.

[0084] In one embodiment, the original data includes transmission data of at least one uplink channel. Converting the original data to obtain target data may include obtaining a conversion strategy corresponding to the uplink channel based on the channel state information of the uplink channel, converting the transmission data of the uplink channel according to the conversion strategy, and obtaining target data of the uplink channel. It should be noted that there are no excessive restrictions on the type of channel state information. For example, the channel state information includes but is not limited to the channel type, channel performance requirements, etc. Therefore, the method can obtain the conversion strategy of the uplink channel based on the channel state information of the uplink channel, and the acquisition of the conversion strategy is more flexible and accurate.

[0085] In one implementation, after obtaining the target data, the method further includes sending the target data to a baseband unit (Base band Unit, BBU).

[0086] In one implementation, the target data of the PRACH and the target data of other uplink channels are sent to the BBU separately.

[0087] In one implementation, the target data is time domain data, and in this case, the data transmitted between the AAU and the BBU is time domain data.

[0088] In one embodiment, before sending the target data to the BBU, the AAU may also perform a time domain-frequency domain transformation on the target data, that is, at this time, the data transmitted between the AAU and the BBU is frequency domain data, and compared with the time domain data transmitted between the AAU and the BBU, the amount of data transmitted between the AAU and the BBU in this method is less. It should be noted that the specific method of the time domain-frequency domain transformation processing is not too limited, for example, the time domain-frequency domain transformation processing may include Fast Fourier Transform (FFT) processing.

[0089] In summary, according to the data processing method of the embodiment of the present application, the original data sent by the terminal can be received by the first number of antennas in the antenna unit, and the original data can be converted to obtain the target data, and the number of antennas of the target data is the second number, and the second number is less than or equal to the first number. Therefore, the number of antennas of the data can be reduced through data conversion, which greatly reduces the amount of data processed in the base station, helps to reduce the resources consumed by data processing, and reduces the cost of data processing.

[0090] Based on any of the above embodiments, Figure 2 As shown, in step S102, converting the original data to obtain target data may include:

[0091] S201, obtaining an antenna switching matrix.

[0092] In one embodiment, the original data includes transmission data of at least one uplink channel. Acquiring the antenna switching matrix may include acquiring the antenna switching matrix corresponding to the uplink channel based on the channel state information of the uplink channel. It should be noted that the relevant content of the channel state information can be referred to the above embodiment and will not be repeated here. Therefore, the method can acquire the antenna switching matrix of the uplink channel based on the channel state information of the uplink channel, and the acquisition of the antenna switching matrix is ​​more flexible and accurate.

[0093] In one embodiment, obtaining the antenna switching matrix may include obtaining the antenna switching matrix corresponding to the uplink channel based on the access status information of the terminal and the channel status information of the uplink channel. It should be noted that the type of access status information is not excessively limited. For example, the access status information includes but is not limited to the beam parameters of the downlink beam to which the terminal belongs. Therefore, the method can comprehensively consider the access status information and channel status information of the terminal to obtain the antenna switching matrix, and the acquisition of the antenna switching matrix is ​​more flexible and accurate.

[0094] S202, converting the original data based on the antenna conversion matrix to obtain target data.

[0095] For example, the first number is N, the second number is M, N and M are both positive integers, and M≤N, and the original data corresponding to the antennas numbered 0, 1 to N-1 in the antenna unit are Y0, Y1 to Y2 respectively. N-1 The converted antenna numbers are 0, 1 to M-1, and the corresponding target data are R0, R1 to R M-1 .

[0096] The antenna switching matrix is The antenna switching matrix W has N rows and M columns.

[0097] Based on the antenna conversion matrix, the original data is converted to obtain the target data, which can be achieved by the following formula:

[0098]

[0099] Therefore, the method can convert the original data based on the antenna conversion matrix to obtain the target data, so as to reduce the number of antennas for the data.

[0100] Based on any of the above embodiments, Figure 3 As shown, obtaining the antenna switching matrix in step S201 may include:

[0101] S301, obtain beam parameters of a downlink beam of a base station, wherein the beam parameters include at least the number of beams of the downlink beam, and the number of beams is a second number.

[0102] In the embodiments of the present application, there are no excessive restrictions on the type of downlink beam, the type of beam parameters, etc.

[0103] In one implementation, the downlink beam is a downlink beam of a synchronization signal block (Synchronization Signal Block, SSB).

[0104] In one implementation, the downlink beam of the terminal includes at least one of the following: a first downlink beam to which the terminal belongs, and a second downlink beam to which a cell where the terminal is located belongs. It can be understood that the second downlink beam includes the first downlink beam.

[0105] In one implementation, the beam parameters further include at least one of the following: beam layer number, beam identification information, beam weight, horizontal angle, and vertical angle.

[0106] In one implementation, obtaining the beam parameters of a downlink beam of a base station may include the following three possible implementations:

[0107] Method 1: Obtain pre-configured first beam parameters.

[0108] In the embodiment of the present application, the first beam parameter may be pre-configured. In one implementation, the first beam parameter may be uniformly planned by the operator, or planned by the base station manufacturer.

[0109] Method 2: Obtain coverage parameters of the cell and antenna parameters of the antenna unit, and obtain second beam parameters based on the coverage parameters and antenna parameters.

[0110] It should be noted that the cell refers to the cell corresponding to the base station, including the cell where the terminal is located.

[0111] In the embodiment of the present application, the second beam parameter can be obtained based on the coverage parameter and the antenna parameter, so that the beam parameter can be obtained by comprehensively considering the coverage parameter and the antenna parameter. It should be noted that there are no excessive restrictions on the types of coverage parameters and antenna parameters. For example, the coverage parameter includes the horizontal coverage range and the vertical coverage range, and the antenna parameter includes the number of horizontal arrays, the number of vertical arrays, the horizontal resolution, the vertical resolution, the horizontal spacing, and the vertical spacing.

[0112] In one embodiment, obtaining the second beam parameters based on the coverage parameters and the antenna parameters may include obtaining the number of beam layers based on the vertical coverage and the vertical resolution, obtaining the number of sub-beams of any layer based on the horizontal coverage and the horizontal resolution of any layer, obtaining the horizontal angle of each beam in any layer based on the horizontal coverage and the number of sub-beams of any layer, and obtaining the number of beams based on the number of sub-beams of each layer.

[0113] For example, the first number is 64, the antenna unit adopts dual polarization, one polarization direction includes 8 rows and 4 columns of antennas, the number of horizontal arrays is 8, the number of vertical arrays is 4, the horizontal spacing is 0.475 wavelengths, the vertical spacing is 1.9 wavelengths, the horizontal resolution is 14°, and the vertical resolution is 7°.

[0131] In one implementation, generating an antenna switching matrix based on beam parameters may include the following two possible implementations:

[0132] Method 1: Generate antenna switching matrix based on beam weights.

[0133] For example, the antenna unit adopts a dual-polarization mode, the first number is N, the number of downlink beams is 2K, and the second number M=2K. One polarization direction includes K downlink beams, and the beam weight matrices of the downlink beams numbered 0, 1 to K-1 in one polarization direction are S0, S1 to S respectively. K-1 .

[0134] Antenna switching matrix

[0135]

[0136] 0≤x≤N1-1, N1=N / 2.

[0137] Among them, S x is the beam weight matrix of the downlink beam numbered x in a polarization direction, S x The number of rows is N / 2, the number of columns is 1, and A x0 , A x1 to They are all beam weights of the downlink beam numbered x in a polarization direction. I0 is a zero matrix. The number of rows of I0 is N / 2 and the number of columns is 1.

[0138] Method 2: Obtain antenna parameters of the antenna unit, and generate an antenna conversion matrix based on the horizontal angle, vertical angle and antenna parameters.

[0139] In the embodiment of the present application, the antenna switching matrix can be generated by comprehensively considering the horizontal angle, vertical angle and antenna parameters, and the acquisition of the antenna switching matrix is ​​more flexible and accurate. It should be noted that there are no excessive restrictions on the types of antenna parameters. For example, the antenna parameters include but are not limited to the number of horizontal arrays, the number of vertical arrays, the horizontal spacing, and the vertical spacing.

[0140] In one embodiment, generating an antenna switching matrix based on the horizontal angle, vertical angle and antenna parameters may include obtaining the horizontal vector of any downlink beam based on the horizontal angle, the number of horizontal elements and the horizontal spacing of any downlink beam, obtaining the vertical vector of any downlink beam based on the vertical angle, the number of vertical elements and the vertical spacing of any downlink beam, obtaining the beam vector of any downlink beam based on the horizontal vector and vertical vector of any downlink beam, and generating the antenna switching matrix based on the beam vector of each downlink beam.

[0141] In one embodiment, based on the horizontal angle of any downlink beam Horizontal array number B and horizontal spacing d H , get the horizontal vector of any downlink beam This can be achieved by the following formula:

[0142]

[0143]

[0144] Where λ is the wavelength.

[0145] In one embodiment, based on the vertical angle θ, the number of vertical arrays A and the vertical spacing d of any downlink beam v , the vertical vector f(θ) of any downlink beam can be obtained by the following formula:

[0146] f(θ)=[1,e -j*2π*α …e -j*2π*(A-1)*α ]

[0147]

[0148] In one embodiment, based on the horizontal vector of any downlink beam and the vertical vector f(θ)f(θ), we can get the beam vector of any downlink beam This can be achieved by the following formula:

[0149]

[0150] In one embodiment, the antenna unit adopts a dual-polarization mode, the first number is N, the number of beams of the downlink beam is 2L, and the second number M=2L. One polarization direction includes L downlink beams, and the beam vectors of the downlink beams numbered 0, 1 to L-1 in one polarization direction are respectively

[0151] The antenna switching matrix W is as follows:

[0152]

[0153] Among them, I0 is a zero matrix, the number of rows of I0 is N / 2, and the number of columns is 1.

[0154] Therefore, the method can generate an antenna switching matrix based on the beam parameters of the downlink beam of the base station.

[0155] On the basis of any of the above embodiments, when the downlink beam is the second downlink beam to which the cell where the terminal is located belongs, after the antenna switching matrix is ​​generated based on the beam parameters of the second downlink beam, the generated antenna switching matrix may also be updated, which may include the following two possible implementations:

[0156] Method 1: Obtain a first downlink beam, and update a generated antenna switching matrix based on beam parameters of the first downlink beam.

[0157] In an embodiment of the present application, the generated antenna conversion matrix can be updated based on the beam parameters of the first downlink beam, and the number of beams of the first downlink beam is less than the number of beams of the second downlink beam, that is, the method can further reduce the number of data antennas by updating the antenna conversion matrix.

[0158] In one implementation, obtaining the first downlink beam may include receiving feedback information sent by the terminal, and obtaining the first downlink beam based on the feedback information, wherein the feedback information carries beam parameters. It is understandable that the second downlink beam includes the first downlink beam, that is, the number of beams of the first downlink beam is less than the number of beams of the second downlink beam. It should be noted that the feedback information and the related contents of obtaining the first downlink beam based on the feedback information can all be referred to the above embodiments, and will not be repeated here.

[0159] In one embodiment, updating the generated antenna switching matrix based on the beam parameters of the first downlink beam may include updating the generated antenna switching matrix based only on the beam parameters of the first downlink beam. For example, the antenna switching matrix is ​​regenerated based only on the beam parameters of the first downlink beam, and the previously generated antenna switching matrix is ​​replaced with the regenerated antenna switching matrix. Thus, the method updates the antenna switching matrix based only on the beam parameters of the first downlink beam to which the terminal belongs, which can greatly reduce the number of antennas for data compared to generating the antenna switching matrix based on the beam parameters of the second downlink beam to which the cell to which the terminal belongs.

[0160] In one embodiment, updating the generated antenna switching matrix based on the beam parameters of the first downlink beam may include obtaining an adjacent downlink beam within a preset range of distance from the first downlink beam, and updating the generated antenna switching matrix based on the beam parameters of the first downlink beam and the adjacent downlink beam. For example, based on the beam parameters of the first downlink beam and the adjacent downlink beam, the antenna switching matrix is ​​regenerated, and the previously generated antenna switching matrix is ​​replaced with the regenerated antenna switching matrix. It should be noted that there are no excessive restrictions on the preset range, and the preset range may be a preset angle range. Therefore, the method updates the antenna switching matrix based on the beam parameters of the first downlink beam and the adjacent downlink beam to which the terminal belongs. Compared with generating the antenna switching matrix based on the beam parameters of the second downlink beam to which the terminal belongs, the method can greatly reduce the number of antennas for data, and the receiving performance of the base station is better.

[0161] Method 2: Detect the RSRP of the second downlink beam, sort the second downlink beams from large to small according to RSRP, determine the first N second downlink beams in the sort as the target downlink beams, where N is a positive integer, N is less than or equal to the number of beams, and update the generated antenna conversion matrix based on the beam parameters of the target downlink beam.

[0162] In an embodiment of the present application, a target downlink beam with a larger RSRP can be screened out from the second downlink beam, and the generated antenna conversion matrix is ​​updated based on the beam parameters of the target downlink beam. The number of beams of the target downlink beam is less than the number of beams of the second downlink beam, that is, the method can further reduce the number of data antennas by updating the antenna conversion matrix.

[0163] In one implementation, there are no excessive restrictions on N, and N may be set to 3, for example.

[0164] In one implementation, the RSRP of the target downlink beam is greater than or equal to a preset threshold, wherein the preset threshold is not excessively limited.

[0165] Therefore, after the method generates the antenna switching matrix based on the beam parameters of the second downlink beam, the generated antenna switching matrix can also be updated to make the antenna switching matrix more accurate and flexible.
