[Technical field]

[0001] The present disclosure relates to the field of communications, and more particularly to signal processing devices and data transmission methods. [Background technology]

[0002] In current cellular wireless communication systems, distributed access network equipment is used as the main form of access network equipment. Some distributed access network equipment includes a baseband unit (BBU) and a radio remote unit (RRU), and the first frequency band range supported by the distributed access network equipment is limited. With the development of technology, other distributed access network equipment includes a BBU and an active antenna unit (AAU), and supports a second frequency band range different from the first frequency band range.

[0003] In order to meet the requirements of various services, operators need to provide access network equipment that supports both a first frequency band range and a second frequency band range. Currently, operators deploy both RRUs and AAUs to achieve this purpose. However, the RRUs and AAUs need to be installed separately, which leads to high complexity and excessive hardware costs.

It can be understood that the first signal processing device can support two different division modes at the same time, thereby meeting the requirements of various services. In this way, there is no need to deploy the RRU and the AAU separately, thereby reducing the complexity and cost.

[0007] In some possible implementations, the scheduling module is coupled to the interface module, the antenna module, the first processing module, and the second processing module.

For example, the terminal equipment may include a mobile phone, a station, a unit, a device, a mobile terminal (MT), a subscriber station, a mobile subscriber station, an Internet node, a communicator, a desktop computer, a laptop computer, a notebook computer, a tablet computer, a personal communication system device, a personal navigation device, a personal digital assistant (PDA), a positioning device, a radio broadcast receiver, an electronic book device, a game device, an Internet of Things (IoT) device, an in-vehicle device, an aircraft, a virtual reality (VR) device, an augmented reality (AR) device, a wearable device, a terminal device in a 5G network, any terminal device in an evolved public land mobile network (PLMN), another device that can be used for communication, or any combination thereof. This is not limited to the embodiments of the present disclosure.

[0105] The term "network equipment" in this disclosure is an entity or node, and may be, for example, an access network equipment that may be configured to communicate with terminal equipment. The access network equipment may be a device, for example, a Radio Access Network (RAN) network equipment that is deployed in a radio access network and provides wireless communication capabilities to mobile terminals. The access network equipment may include various types of base stations. For example, the access network equipment may include various forms of macro base stations, micro base stations, pico base stations, femto base stations, relay stations, access points, remote radio units (RRUs), radio heads (RHs), and remote radio heads (RRHs), and the like. In systems using different radio access technologies, the names of the access network equipment may also be different. For example, the access network equipment may be referred to as evolved NodeB (eNB or eNodeB) in a Long Term Evolution (LTE) network, NodeB (NodeB, NB) in a 3G network, and gNodeB (gNB) or NR NodeB (NR NB) in a 5G network. In some scenarios, the access network equipment may include a Central Unit (CU) and / or a Distributed Unit (DU). The CU and DU may be located in different locations. For example, the DU is located in a remote location and in an area with high traffic volume, and the CU is located in a central equipment room. Alternatively, the CU and DU may be located in the same equipment room. Alternatively, the CU and DU may be different components in a rack. For ease of explanation, in the following embodiments of the present disclosure, the above-mentioned devices that provide wireless communication capabilities to terminal equipment are collectively referred to as network equipment. This is not particularly limited in the embodiments of the present disclosure.

[0106] Distributed access network equipment is the predominant form of access network equipment in current cellular wireless communication systems.

[0107] 1 is a schematic block diagram showing a distributed access network equipment 100. In FIG. 1, the distributed access network equipment 100 includes a BBU 110 and an RRU 120, which are connected via an optical fiber 130. The RRU 120 may be connected to an antenna 102 via a feeder 101 so as to be able to communicate with a terminal equipment 140.

[0108] The optical fiber 130 in Fig. 1 may be a cable according to the Common Public Radio Interface (CPRI) protocol. The CPRI protocol is one of the current standard radio interface protocols used to connect the BBU and the RRU. Furthermore, in the CPRI protocol, the BBU is also called Radio Equipment Control (REC) and the RRU is also called Radio Equipment (RE).

[0109] The RRU 120 may include four modules, namely, a digital intermediate frequency module, a transceiver module, a power amplification module, and a filtering module. The downlink transmission from the distributed access network equipment 100 to the terminal equipment 140 is used as an example. The digital intermediate frequency module may be configured to perform modulation and demodulation, digital up-conversion and down-conversion, analog / digital (A / D) conversion, and the like during optical transmission. The transceiver module is configured to implement conversion from the intermediate frequency signal to a radio frequency signal. The converted radio frequency signal may then pass through the power amplification module and the filtering module and be transmitted to the terminal equipment 140 via the antenna 102.

[0110] In the distributed access network equipment 100 shown in Fig. 1, a time domain division mode is used. In other words, the BBU 110 completes processing in the Media Access Control (MAC) layer, the physical layer, and the like, and the RRU 120 completes the Radio Frequency (RF) processing. Furthermore, the carrier supported by the RRU 120 is within a first frequency band range, such as the 1.8 GHz frequency band.

[0111] Fig. 2 is another schematic block diagram showing a distributed access network device 200. In Fig. 2, the distributed access network device 200 includes a BBU 210 and an AAU 220, which are connected via an optical fiber 230. The AAU 220 includes an antenna module, so that it can communicate with a terminal device 240. Optionally, the BBU 210 may include a CU and a DU, which are not shown in Fig. 2.

[0112] The optical fiber 230 may be a cable according to the Enhanced Common Public Radio Interface (eCPRI) protocol. The distributed access network equipment 200 shown in FIG. 2 supports Massive Multiple Input Multiple Output (Massive MIMO) and can use split mode inside the physical layer. In other words, the BBU 210 completes the processing of the MAC layer, the upper physical layer, and the like, and the AAU 220 completes the processing of the lower physical layer and RF processing. Furthermore, the carrier supported by the AAU 220 is within a second frequency band range, for example, the 2.1 GHz frequency band.

[0113] 3 is a schematic diagram illustrating various partitioning modes 300. FIG 3 illustrates a time domain partitioning mode 310, such as Option-8, and further illustrates partitioning modes 320 within the physical layer, such as Option 7-1, Option 7-2, and Option 7-3.

[0114] With reference to Figure 3, option 7-1 is used as an example. That is, for downlink transmission, the BBU performs coding, rate matching, scrambling, modulation, layer mapping, precoding, Resource Element (RE) mapping, Beamforming (BF) port expansion, and the like in the upper physical layer, and the AAU performs inverse Fast Fourier Transform (iFFT), Cyclic Prefix (CP) addition, and the like in the lower physical layer. For uplink transmission, the AAU performs CP removal and Fast Fourier Transform (FFT) in the lower physical layer, and the BBU performs port reduction, RE de-mapping, channel estimation, diversity combining, equalization, inverse Discrete Fourier Transform (iDFT), demodulation, de-scrambling, rate de-matching, decoding, and the like in the upper physical layer. Options 7-2 and 7-3 may be described with reference to FIG. 3 and are not described in this disclosure.

[0115] For example, see Section 4.2 of 3GPP TS 38.816 (e.g., 15.0.0, etc.) for options 7-1, 7-2, and 7-3. For option 8, see Section 11.1.2.8 of 3GPP TS 38.801 (e.g., 14.0.0, etc.). However, it should be noted that the division scheme shown in FIG. 3 is merely an example and cannot be construed as a limitation on the embodiments of the present disclosure.

[0116] It may also be understood that the split mode in the present disclosure may be referred to as a split scheme, a protocol split mode, or the like. In some scenarios, the split mode may represent splitting into an RRU and a BBU, or into an AAU and a BBU. For example, if a BBU includes a CU and a DU, the split scheme may represent splitting into an AAU and a DU.

[0117] As described above, the RRU is connected to the BBU via a CPRI interface and supports a first frequency band range. The AAU is connected to the BBU via an eCPRI interface and supports a second frequency band range. To meet the requirements of different services, the operator needs to provide an access network device that simultaneously supports the first frequency band range and the second frequency band range. The method of separately deploying the RRU and the BBU not only has a complicated configuration, but also incurs high costs.

[0118] Due to the above-mentioned problems and other potential problems in similar scenarios, the embodiments of the present disclosure provide a signal processing device, which can be connected to a second signal processing device via an optical fiber and can support two different split modes, i.e., a first frequency band range and a second frequency band range simultaneously. In this way, the hardware complexity in the device can be reduced, and the installation cost can be reduced. Hereinafter, the embodiments of the present disclosure will be described in detail with reference to Figures 4 to 11. It can be understood that the embodiments of the present disclosure are not limited to the scenarios of BBU and RRU, and BBU and AAU, but can be further applicable to other scenarios.

The second scheduling submodule 520 may be configured to schedule uplink data from the antenna module 415 to the first processing module 413 or the second processing module 414 based on the transmission configuration information from the second signal processing device 420.

The conversion submodule 530 may be configured to implement a conversion between Ethernet data and time domain data. The beamforming submodule 540 may be configured to implement a conversion between a first quantity of multi-channel first time domain data and a second quantity of multi-channel second time domain data. The first quantity is less than the second quantity. For example, the first quantity may be any one of 1, 2, 4, or 8, and the second quantity may be any one of 32, 64, or 128. However, it should be noted that the listed values ​​of the first quantity and the second quantity in the present disclosure are merely examples and should not be construed as limitations on the embodiments of the present disclosure.

[0125] In some examples, the conversion sub-module 530 implementing the conversion function may be understood to be called a data bridge or another name. This is not limited in the present disclosure. In an embodiment of the present disclosure, the scheduling module 412 may be configured by a control plane (not shown) of the first signal processing device 410, for example, according to a division mode corresponding to different carriers.

[0126] In some embodiments of the present disclosure, the first signal processing device 410 may be obtained by upgrading and reconstructing the AAU 220 shown in Fig. 2. For example, based on the AAU 220 shown in Fig. 2, the AAU 220 is upgraded to the first signal processing device 410 by adding a scheduling module 412 and a first processing module 413. In this way, the existing equipment can be fully utilized, which can avoid large-scale equipment replacement and further reduce costs.

[0127] As shown in FIG. 4, the second signal processing device 420 may include a first baseband module 421, a second baseband module 422, a conversion module 423, and an interface module 424. The first baseband module 421 is connected to the conversion module 423, and the conversion module 423 and the second baseband module 422 are connected to the interface module 424. The first baseband module 421 may be configured to generate or process time domain data. The second baseband module 422 may be configured to generate or process Ethernet data. The conversion module 423 may be configured to implement conversion between the time domain data and the Ethernet data.

Specifically, the conversion module 423 may convert the time domain data from the first baseband module 421 to Ethernet data, and may convert the Ethernet data from the interface module 424 to time domain data.

The scheduling module 425 may be configured to schedule Ethernet data from the interface module 424 to the conversion module 423 or the second baseband module 422. Accordingly, the conversion module 423 may convert the Ethernet data from the scheduling module 425 into time domain data, and then provide the converted time domain data to the first baseband module 421.

[0129] In some examples, it may be understood that the conversion module 423 implementing the conversion function may be referred to as a data bridge or another name, and this is not a limitation of this disclosure. In some examples, it may be understood that the scheduling module 425 may implement an Ethernet data distribution function, and accordingly, the scheduling module 425 may be referred to as a distribution module, and this is not a limitation of this disclosure.

[0130] In some embodiments of the present disclosure, the second signal processing device 420 may be obtained by upgrading and reconstructing the BBU 110 shown in FIG. 1 or the BBU 210 shown in FIG. 2. For example, based on the BBU 110 shown in FIG. 1, the BBU 110 is upgraded to the second signal processing device 420 by adding a second baseband module 422 and a conversion module 423 and replacing the original CPRI interface with an eCPRI interface. Based on the BBU 210 shown in FIG. 2, the BBU 210 is upgraded to the second signal processing device 420 by adding a second baseband module 422 and a conversion module 423 and replacing the original CPRI interface with an eCPRI interface. two Baseband module 422 and a conversion module 423. In this way, the existing equipment can be fully utilized, which can avoid large-scale equipment replacement and further reduce costs.

[0131] A transmission sent via the antenna module 415 of the first signal processing device 410 from the second signal processing device 420 to the first signal processing device 410 is called a downlink transmission. A transmission received by the antenna module 415 of the first signal processing device 410 from the first signal processing device 410 to the second signal processing device 420 is called an uplink transmission.

[0132] Although Fig. 4 and Fig. 5 show that the first signal processing device 410 includes multiple modules and the second signal processing device 420 includes multiple modules, it should be noted that the modules in Fig. 4 or Fig. 5 are merely examples. In a practical scenario, the first signal processing device 410 and the second signal processing device 420 may include fewer modules or may include a larger number of modules. For example, the antenna module 415 may be independent of the first signal processing device 410, in other words, the first signal processing device 410 may not include the antenna module 415, etc. This is not described in this disclosure.

[0133] It should be understood that the division into modules or units in the embodiments of the present disclosure is an example and is merely a logical division of functions. In actual implementation, there may be other division methods. Furthermore, the functional units in the embodiments of the present disclosure may be integrated into one unit, or each of the functional units may exist physically alone, or two or more units may be integrated into one unit. The integrated unit may be implemented in the form of hardware or in the form of a software functional unit.

[0134] Some embodiments of the present disclosure will now be described in more detail with reference to the signaling interaction diagrams shown in FIGS.

[0135] 6 is a signaling interaction diagram illustrating a data transmission process 600 according to some embodiments of the present disclosure. FIG. 6 relates to a first signal processing device 410 and a second signal processing device 420, and the process 600 is a downlink transmission from the second signal processing device 420 to the first signal processing device 410.

[0136] In operation 610, the first baseband module 421 in the second signal processing device 420 generates time-domain data. Specifically, the first baseband module 421 may generate the time-domain data by performing a series of operations, such as encoding, rate matching, ..., and CP addition.

[0137] The time domain data may also be referred to as In-phase / Quadrature (I / Q) data, or as baseband quadrature sampling data, or as CPRI data or another name, which is not limited in this disclosure. Optionally, the time domain data generated by the first baseband module 421 may be digital baseband data obtained by in-phase or quadrature modulation on a user plane.

[0138] The time domain data generated by the first baseband module 421 may include multiple I / Q data streams corresponding to a first number of antenna channels. Optionally, the time domain data generated by the first baseband module 421 may be referred to as multi-channel first I / Q data, where the quantity indicated by the term “multi-channel” is equal to a first quantity, such as any value of 1, 2, 4, or 8, for example.

[0139] The basic unit of time domain data transmission is a base frame. For example, the duration of one base frame is 1 / 3.84MHz=260.41667 nanoseconds (ns). One base frame may include 16 sampling points, the first sampling point is used to transmit a control word, and the second to 16th sampling points are used to transmit I / Q data. For ease of explanation, the remaining 15 sampling points other than the first sampling point in the base frame may be called chips, in other words, one base frame includes one sampling point transmission control word and 15 sampling points chips.

[0140] In the above example, the chip includes 15 sampling points, but it can be understood that the embodiments of the present disclosure are not limited thereto. For example, the number of sampling points included in the chip may be equal to 8, or may be equal to another value. Furthermore, the above-mentioned "sampling points" may be referred to as a word, another name, or the like. This is not limited in the present disclosure.

[0141] The bit width of a sampling point may represent how many bits are included in the sampling point. Therefore, it can be understood that the bit width can be used to determine the quantity of bits included in the chip. In a specific implementation, the baseband configuration information of the first baseband module 421 may include the bit width, in other words, the bit width may be preconfigured in the first baseband module 421. The specific value of the bit width is not limited in the embodiment of the present disclosure. For example, the bit width may be equal to 15 bits or may be equal to another value.

[0142] In operation 620, the conversion module 423 of the second signal processing device 420 converts the time domain data to Ethernet data.

[0143] Specifically, the conversion module 423 may perform packet assembly on multiple chips in the time domain data to obtain corresponding Ethernet data.

[0144] In some embodiments, the conversion module 423 may concatenate chips in the time domain data in sequence and use the concatenated data as the payload of the Ethernet data. Figure 7 is a schematic diagram illustrating a case 700 in which time domain data is converted to Ethernet data according to some embodiments of the present disclosure.

[0145] As shown in FIG. 7, the basic unit of the time domain data 710 is a base frame 712, which includes a control word 7121 and a chip 7122. .stomach The Ethernet data 720 may include a transport network layer header 721, a common header 722, a service header 723, and a payload 724, and may optionally also include padding 725. For example, packet assembly may be performed on multiple chips 7122, which are used as the payload 724 of the Ethernet data 720.

[0146] In some embodiments of the present disclosure, the number of chips included in a packet of Ethernet data 720 may be determined based on the following factors: the first quantity, the number of sampling points included in the chip, the bit width of the sampling points, and the transmission bandwidth.

[0147] For example, assume that the bandwidth is 20 MHz, the Maximum Transmission Unit (MTU) of Ethernet data corresponding to this bandwidth is 1500 bytes, and the length of the packet header is 64 bytes. Assume that the first quantity is equal to 4, the quantity of sampling points included in a chip is equal to 8, and the bit width of the sampling point is equal to 15. In one example, the quantity of multiple chips can be obtained by rounding down (1500-64) / (4×8×15×2 / 8), that is, it can be determined to be 11. In this way, the transmission bandwidth can be fully utilized, the transmission efficiency of Ethernet can be ensured, and resource waste can be avoided.

[0148] It can be understood that the above-mentioned manner of determining the quantity of the plurality of chips is merely an example. In a practical scenario, the quantity of the plurality of chips may be equal to another value, for example, a value less than the quantity determined in the above-mentioned manner, such as 10 or 9. This is not limited in the present disclosure.

[0149] In operation 630, the interface module 424 of the second signal processing device 420 transmits the Ethernet data to the first signal processing device 410 via the optical fiber 430. In response, the interface module 411 of the first signal processing device 410 may receive the Ethernet data from the second signal processing device 420.

[0150] In operation 640, the scheduling module 412 of the first signal processing device 410 schedules the Ethernet data to the first processing module 413 based on the transmission configuration information.

[0151] In some embodiments of the present disclosure, the transmission configuration information may be pre-sent by the second signal processing device 420 to the first signal processing device 410. See Fig. 6. In operation 601, the interface module 424 of the second signal processing device 420 transmits the transmission configuration information to the first signal processing device 410. In response, the interface module 411 of the first signal processing device 410 may receive the transmission configuration information.

[0152] In some embodiments, the transmission configuration information may include indication information indicating whether processing is performed by the first processing module 413. For example, the indication information may be understood as a switch used to process data by the first processing module 413, and may be, for example, 1 or 0. It may be understood that the indication information may alternatively be in another form. This is not limited in the present disclosure. If the indication information indicates that processing is performed by the first processing module 413, the scheduling module 412 of the first signal processing device 410 schedules the Ethernet data received from the interface module 411 to the first processing module 413. If the indication information indicates that processing is not performed by the first processing module 413, the scheduling module 412 of the first signal processing device 410 schedules the Ethernet data received from the interface module 411 to the second processing module 414.

[0153] In some embodiments, the transmission configuration information may include first instruction information and second instruction information. The first instruction information indicates a correspondence between a first frequency band range and the first processing module 413, and the second instruction information indicates a correspondence between a second frequency band range and the second processing module 414. For example, a specific field of the Ethernet data received from the interface module 411 may carry frequency information. If the frequency information is within the first frequency band range, the scheduling module 412 of the first signal processing device 410 schedules the Ethernet data received from the interface module 411 to the first processing module 413. If the frequency information is within the second frequency band range, the scheduling module 412 of the first signal processing device 410 schedules the Ethernet data received from the interface module 411 to the second processing module 414.

[0154] It should be noted that the transmission configuration information in the embodiment of the present disclosure may alternatively include another instruction form, so that the scheduling module 412 may determine to schedule the Ethernet data from the interface module 411 to the first processing module 413 or the second processing module 414 based on the transmission configuration information. In the process 600 in FIG. 6, it is assumed that the scheduling module 412 schedules the Ethernet data to the first processing module 413.

[0155] The first processing module 413 processes the Ethernet data from the scheduling module 412 according to a first partitioning mode. The first partitioning mode may be a time domain partitioning mode. Optionally, the first partitioning mode may be a partitioning mode supporting a CPRI protocol. Referring to FIG. 3, the first partitioning mode may be option 8 shown in FIG. 3. For example, the first processing module 413 performs RF processing on the Ethernet data but does not perform processing at the physical layer.

[0156] See Figure 6. In operation 650, the conversion sub-module 530 converts the Ethernet data into time domain data. Specifically, the conversion sub-module 530 may convert the Ethernet data into a first quantity of multi-channel first time domain data.

[0157] In some embodiments of the present disclosure, the first quantity may be preconfigured by the second signal processing device 420 to the first signal processing device 410. In some embodiments, for example, the transmission configuration information in operation 601 may include the first quantity. In some other embodiments, the first quantity may be independent of the transmission configuration information, for example, the second signal processing device 420 informs the first signal processing device 410 of the first quantity based on another portion of the separate signaling.

[0158] The conversion sub-module 530 may determine a corresponding first quantity of multi-channel first time domain data based on a division of a payload of the Ethernet data. The Ethernet payload may be an eCPRI payload. The conversion sub-module 530 may divide the payload based on a size of a chip and add a control word to the chip to obtain a base frame, thereby obtaining the multi-channel first time domain data.

[0159] The beamforming sub-module 540 transforms a first quantity of multi-channel first time domain data into a second quantity of multi-channel second time domain data, the second quantity being greater than the first quantity.

[0160] Specifically, the beamforming submodule 540 may determine a second quantity of multi-channel second time domain data based on a first quantity of multi-channel first time domain data and a plurality of first antenna weight parameters.

[0161] In some embodiments of the present disclosure, the second quantity and / or the plurality of first antenna weight parameters may be preconfigured for the first signal processing device 410 by the second signal processing device 420. In some embodiments, for example, the transmission configuration information in operation 601 may include the second quantity and / or the plurality of first antenna weight parameters. In some other embodiments, the second quantity and / or the plurality of first antenna weight parameters may be independent of the transmission configuration information. For example, the second signal processing device 420 may notify the first signal processing device 410 of the second quantity and / or the plurality of first antenna weight parameters based on another part of the separate signaling. For example, the second quantity may correspond to the number of antenna channels of the antenna module 415. For example, the second quantity may be less than or equal to the total number of channels of the antenna module 415.

[0162] For ease of explanation, the first quantity may be represented as N1, the second quantity may be represented as N2, and N1 < N2. In some embodiments, at least a part of the N1-channel first time domain data may be replicated to obtain the N2-channel time domain data, and then a part of each of the N2-channel time domain data is multiplied by the corresponding first antenna weight parameter to obtain the N2-channel second time domain data.

[0163] For example, assume N1=4 and N2=32. Each of the N1 channel first time domain data may be replicated to obtain eight copies to obtain 32 channel time domain data. For example, the first channel time domain data in the 32 channel time domain data through the eighth channel time domain data in the 32 channel time domain data is the first channel first time domain data in the N1 channel first time domain data, the 9th channel time domain data in the 32 channel time domain data through the sixteenth channel time domain data in the 32 channel time domain data is the second channel first time domain data in the N1 channel first time domain data, the 17th channel time domain data in the 32 channel time domain data through the twenty-fourth channel time domain data in the 32 channel time domain data is the third channel first time domain data in the N1 channel first time domain data, and the 25th channel time domain data in the 32 channel time domain data through the thirty-second channel time domain data is the fourth channel first time domain data in the N1 channel first time domain data. Optionally, the plurality of first antenna weighting parameters is a second quantity of the plurality of first antenna weighting parameters, which may be expressed consecutively as wt1, wt2, ..., and wtN2. In this manner, the i-th channel time domain data in the 32-channel time domain data may be multiplied by wti (where i=1, 2, ..., N2) to obtain the i-th channel second time domain data in the N2-channel second time domain data.

[0164] It should be noted that the embodiment in which the beamforming submodule 540 obtains a second quantity of multi-channel second time domain data based on a first quantity of multi-channel first time domain data is merely an example, and the present disclosure is not limited thereto. For example, the beamforming submodule 540 may duplicate the j-th channel (where j=1, 2, ..., N1) first time domain data in the N1 channel first time domain data to obtain N2 copies, and multiply each of the N2 copies by the corresponding first antenna weight parameter wti (where i=1, 2, ..., N2) obtained.

[0165] It should be noted that the data processing process performed by the first processing module 413 described in the embodiment of the present disclosure is merely an example. In a practical scenario, other processing such as power amplification and filtering may be further included.

[0166] In operation 670, the antenna module 415 of the first signal processing device 410 transmits the multi-channel second time domain data. Specifically, the antenna module 415 may transmit the N2-channel second time domain data to the terminal device via the N2 antenna channels in the antenna module 415.

[0167] In this manner, the conversion module 423 of the second signal processing device 420 in the embodiment of the present disclosure can convert the time domain data into Ethernet data, so that the Ethernet data can be transmitted to the first signal processing device 410 via the eCPRI optical fiber. In this manner, a larger number of cells can be supported, and the air interface performance is improved. Furthermore, the first processing module 413 in the first signal processing device 410 can process the Ethernet data from the second signal processing device 420 according to a first division mode to support a first frequency band range.

[0168] 8 is a signaling interaction diagram illustrating a data transmission process 800 according to some embodiments of the present disclosure. FIG 8 relates to a first signal processing device 410 and a second signal processing device 420, and the process 800 is a downlink transmission from the second signal processing device 420 to the first signal processing device 410.

[0169] In operation 810, the second baseband module 424 of the second signal processing device 420 generates Ethernet data.

[0170] In operation 820, the interface module 424 of the second signal processing device 420 transmits the Ethernet data to the first signal processing device 410 via the optical fiber 430. In response, the interface module 411 of the first signal processing device 410 may receive the Ethernet data from the second signal processing device 420.

[0171] In operation 830, the scheduling module 412 of the first signal processing device 410 schedules the Ethernet data to the second processing module 414 based on the transmission configuration information.

[0172] In some embodiments of the present disclosure, the transmission configuration information may be pre-sent by the second signal processing device 420 to the first signal processing device 410. See Fig. 8. In operation 801, the interface module 424 of the second signal processing device 420 transmits the transmission configuration information to the first signal processing device 410. In response, the interface module 411 of the first signal processing device 410 may receive the transmission configuration information. For the transmission configuration information, see the embodiment described with reference to operation 601 in Fig. 6. For the sake of brevity, details will not be described herein.

[0173] In operation 840, the second processing module 414 processes the Ethernet data from the scheduling module 412 according to a second partitioning mode. The second partitioning mode may be a partitioning mode within the physical layer. Optionally, the second partitioning mode may be a partitioning mode supporting the eCPRI protocol. With reference to FIG. 3, the second partitioning mode may be option 7-1, option 7-2, or option 7-3 shown in FIG. 3. For example, the second processing module 414 performs lower physical layer processing and RF processing on the Ethernet data, but does not perform upper physical layer processing. For example, the second partitioning mode is option 7-1. The processing performed by the second processing module 414 may include operations such as iFFT and CP addition.

[0174] It should be noted that the data processing process performed by the second processing module 414 described in the embodiment of the present disclosure is merely an example. In a practical scenario, the processing process may include, for example, frequency domain beamforming, power amplification, and filtering. In some examples, for specific operations performed by the second processing module 414, please refer to the operations performed by the AAU in the prior art.

[0175] In operation 850, the antenna module 415 of the first signal processing device 410 transmits downlink data.

[0176] In this manner, the second baseband module 422 of the second signal processing device 420 in the embodiment of the present disclosure generates Ethernet data, so that the Ethernet data can be transmitted to the first signal processing device 410 via the eCPRI optical fiber. Furthermore, the second processing module 414 in the first signal processing device 410 can process the Ethernet data from the second signal processing device 420 according to a second division mode to support a second frequency band range.

[0177] 9 is a signaling interaction diagram illustrating a data transmission process 900 according to some embodiments of the present disclosure. FIG 9 relates to a first signal processing device 410 and a second signal processing device 420, and the process 900 is an uplink transmission from the first signal processing device 410 to the second signal processing device 420.

[0178] In operation 910, the antenna module 415 of the first signal processing device 410 receives uplink data. For example, the uplink data may come from a terminal device. Optionally, a second number of antenna channels in the antenna module 415 may receive multi-channel data, which is referred to as, for example, a second number of multi-channel second time domain data.

[0179] In an operation 920, the scheduling module 412 of the first signal processing device 410 schedules the uplink data to the first processing module 413 based on the transmission configuration information.

[0180] In some embodiments of the present disclosure, the transmission configuration information may be pre-sent by the second signal processing device 420 to the first signal processing device 410. See Fig. 9. In operation 901, the interface module 424 of the second signal processing device 420 transmits the transmission configuration information to the first signal processing device 410. In response, the interface module 411 of the first signal processing device 410 may receive the transmission configuration information.

[0181] In some embodiments, the transmission configuration information may include instruction information indicating whether processing is performed by the first processing module 413. For example, the instruction information may be understood as a switch used to process data by the first processing module 413, and may be, for example, 1 or 0. It may be understood that the instruction information may alternatively be in another form. This is not limited in the present disclosure. If the instruction information indicates that processing is performed by the first processing module 413, the scheduling module 412 of the first signal processing device 410 schedules the uplink data received from the antenna module 415 to the first processing module 413. If the instruction information indicates that processing is not performed by the first processing module 413, the scheduling module 412 of the first signal processing device 410 schedules the uplink data received from the antenna module 415 to the second processing module 414.

[0182] In some embodiments, the transmission configuration information may include first instruction information and second instruction information. The first instruction information indicates a correspondence between the first frequency band range and the first processing module 413, and the second instruction information indicates a correspondence between the second frequency band range and the second processing module 414. For example, a specific field of the uplink data received from the antenna module 415 may carry frequency information. If the frequency information is within the first frequency band range, the scheduling module 412 of the first signal processing device 410 schedules the uplink data received from the antenna module 415 to the first processing module 413. If the frequency information is within the second frequency band range, the scheduling module 412 of the first signal processing device 410 schedules the uplink data received from the antenna module 415 to the second processing module 414.

[0183] It should be noted that the transmission configuration information in the embodiment of the present disclosure may alternatively include another indication form, so that the scheduling module 412 may determine to schedule the uplink data received from the antenna module 415 to the first processing module 413 or the second processing module 414 based on the transmission configuration information. In the process 900 in FIG. 9, it is assumed that the scheduling module 412 schedules the uplink data to the first processing module 413.

[0184] The first processing module 413 processes the uplink data from the scheduling module 412 according to a first partitioning mode. The first partitioning mode may be a time domain partitioning mode. Optionally, the first partitioning mode may be a partitioning mode supporting a CPRI protocol. Referring to FIG. 3, the first partitioning mode may be option 8 shown in FIG. 3. For example, the first processing module 413 performs RF processing on the uplink data but does not perform physical layer processing.

[0185] See Figure 9. In operation 930, the beamforming sub-module 540 transforms the uplink data into a first quantity of multi-channel first time domain data, the first quantity being less than a second quantity.

[0186] In some embodiments of the present disclosure, the first quantity may be preconfigured by the second signal processing device 420 to the first signal processing device 410. In some embodiments, for example, the transmission configuration information in operation 901 may include the first quantity. In some other embodiments, the first quantity may be independent of the transmission configuration information, for example, the second signal processing device 420 informs the first signal processing device 410 of the first quantity based on another portion of the separate signaling.

[0187] The beamforming sub-module 540 may convert a second quantity of multi-channel second time-domain data into a first quantity of multi-channel first time-domain data. Specifically, the beamforming sub-module 540 may determine a first quantity of multi-channel first time-domain data based on a second quantity of multi-channel second time-domain data and a plurality of second antenna weight parameters.

[0188] In some embodiments of the present disclosure, a plurality of second antenna weight parameters may be preconfigured for the first signal processing device 410 by the second signal processing device 420. In some embodiments, for example, the transmission configuration information in operation 901 may include a plurality of second antenna weight parameters. In some other embodiments, the plurality of second antenna weight parameters may be independent of the transmission configuration information. For example, the second signal processing device 420 may notify the first signal processing device 410 of a plurality of second antenna weight parameters based on another part of separate signaling.

[0189] For ease of explanation, the first quantity may be represented as N1, the second quantity may be represented as N2, and N1 < N2. In some embodiments, each of the N2-channel second time-domain data may be multiplied by a corresponding second antenna weight parameter to obtain N2-channel time-domain data, and then at least a portion of the N2-channel time-domain data is combined to obtain N1-channel first time-domain data.

[0190] For example, assume that N1=4 and N2=32. Optionally, the plurality of second antenna weight parameters is a second quantity of the plurality of second antenna weight parameters, and the plurality of second antenna weight parameters may be expressed consecutively as wr1, wr2, ..., and wrN2. The i-th channel second time domain data in the N2 channel second time domain data may be multiplied by wri (i=1, 2, ..., N2) to obtain the i-th channel time domain data in the N2 channel time domain data. Then, the 1st channel time domain data in the N2 channel time domain data through the 8th channel time domain data in the N2 channel time domain data may be combined (e.g., added) to obtain first channel first time domain data in the N1 channel first time domain data, the 9th channel time domain data in the N2 channel time domain data through the 16th channel time domain data in the N2 channel time domain data may be combined (e.g., added) to obtain second channel first time domain data in the N1 channel first time domain data, and the 17th channel time domain data in the N2 channel time domain data through the 24th channel time domain data in the N2 channel time domain data. Time Domain Data may be combined (e.g., added) to obtain a third channel first time domain data in the N1 channel first time domain data, and a 25th channel first time domain data in the N2 channel time domain data. Time Domain Data Through the 32nd channel time domain data in the N2 channel time domain data may be combined (eg, added) to obtain 4th channel first time domain data in the N1 channel first time domain data.

[0191] It should be noted that the data processing process performed by the first processing module 413 described in the embodiment of the present disclosure is merely an example. In a practical scenario, other processing such as power amplification and filtering may be further included.

[0192] In operation 940, the conversion sub-module 530 converts the first quantity of multi-channel first time-domain data into Ethernet data. In particular, the conversion operation performed by the conversion sub-module 530 is similar to the conversion operation 620 performed by the conversion module 423 of the second signal processing device 420 described with reference to Figure 6. For the sake of brevity, details will not be described herein.

[0193] In operation 950, the interface module 411 of the first signal processing device 410 transmits the Ethernet data to the second signal processing device 420. In response, the interface module 424 of the second signal processing device 420 may receive the Ethernet data from the first signal processing device 410.

[0194] In step 960, the scheduling module 425 of the second signal processing device 420 schedules the Ethernet data to the conversion module 423. Specifically, the scheduling module 425 may perform scheduling based on frequency information of the Ethernet data. If the frequency information is within the first frequency band range, the scheduling module 425 of the second signal processing device 420 schedules the Ethernet data received from the interface module 424 to the conversion module 423. If the frequency information is within the second frequency band range, the scheduling module 425 of the second signal processing device 420 schedules the Ethernet data received from the interface module 424 to the second baseband module 422. In the process 900 in FIG. 9, it is assumed that the scheduling module 425 schedules the Ethernet data to the conversion module 423.

[0195] In operation 970, the conversion module 423 of the second signal processing device 420 converts the Ethernet data into time domain data. Specifically, the conversion module 423 may convert the Ethernet data into a first quantity of multi-channel first time domain data.

[0196] The conversion module 423 may determine a corresponding first quantity of multi-channel first time domain data based on a division of a payload of the Ethernet data. The Ethernet payload may be an eCPRI payload. The conversion module 423 may divide the payload based on a size of a chip and add a control word to the chip to obtain a base frame, thereby obtaining the multi-channel first time domain data.

[0197] In operation 980, the first baseband module 421 of the second signal processing device 420 processes the time domain data. Specifically, the first baseband module 421 may process the time domain data by performing a series of operations such as CP removal, FFT, ..., and decoding.

See Fig. 10. In operation 1001, the interface module 424 of the second signal processing device 420 transmits the transmission configuration information to the first signal processing device 410. In response, the interface module 411 of the first signal processing device 410 may receive the transmission configuration information.

[0202] In some embodiments, the transmission configuration information may include instruction information indicating whether processing is performed by the first processing module 413. For example, the instruction information may be understood as a switch used to process data by the first processing module 413, and may be, for example, 1 or 0. It may be understood that the instruction information may alternatively be in another form. This is not limited in the present disclosure. If the instruction information indicates that processing is performed by the first processing module 413, the scheduling module 412 of the first signal processing device 410 schedules the uplink data received from the antenna module 415 to the first processing module 413. If the instruction information indicates that processing is not performed by the first processing module 413, the scheduling module 412 of the first signal processing device 410 schedules the uplink data received from the antenna module 415 to the second processing module 414.

[0203] In some embodiments, the transmission configuration information may include first instruction information and second instruction information. The first instruction information indicates a correspondence between the first frequency band range and the first processing module 413, and the second instruction information indicates a correspondence between the second frequency band range and the second processing module 414. For example, a specific field of the uplink data received from the antenna module 415 may carry frequency information. If the frequency information is within the first frequency band range, the scheduling module 412 of the first signal processing device 410 schedules the uplink data received from the antenna module 415 to the first processing module 413. If the frequency information is within the second frequency band range, the scheduling module 412 of the first signal processing device 410 schedules the uplink data received from the antenna module 415 to the second processing module 414.

[0204] It should be noted that the transmission configuration information in the embodiment of the present disclosure may alternatively include another indication form, so that the scheduling module 412 may determine to schedule the uplink data received from the antenna module 415 to the first processing module 413 or the second processing module 414 based on the transmission configuration information. In the process 1000 in FIG. 10, it is assumed that the scheduling module 412 schedules the uplink data to the second processing module 414.

[0205] In operation 1030, the second processing module 414 processes the uplink data from the scheduling module 412 according to a second partitioning mode. The second partitioning mode may be a partitioning mode within the physical layer. Optionally, the second partitioning mode may be a partitioning mode supporting the eCPRI protocol. With reference to FIG. 3, the second partitioning mode may be option 7-1, option 7-2, or option 7-3 shown in FIG. 3. For example, the second processing module 414 performs lower physical layer processing and RF processing on the Ethernet data, but does not perform upper physical layer processing. For example, the second partitioning mode is option 7-1. The processing performed by the second processing module 414 may include operations such as CP removal and FFT.

[0206] It should be noted that the data processing process performed by the second processing module 414 described in the embodiment of the present disclosure is merely an example. In a practical scenario, the processing process may include, for example, frequency domain beamforming, power amplification, and filtering. In some examples, for specific operations performed by the second processing module 414, please refer to the operations performed by the AAU in the prior art. The processed data of the second processing module 414 may be understood to be Ethernet data.

[0207] In operation 1040, the interface module 411 of the first signal processing device 410 transmits the Ethernet data to the second signal processing device 420. In response, the interface module 424 of the second signal processing device 420 may receive the Ethernet data from the first signal processing device 410.

[0208] In operation 1050, the scheduling module 425 of the second signal processing device 420 schedules the Ethernet data to the second baseband module 422. Specifically, the scheduling module 425 may perform scheduling based on frequency information of the Ethernet data. If the frequency information is within the first frequency band range, the scheduling module 425 of the second signal processing device 420 schedules the Ethernet data received from the interface module 424 to the conversion module 423. If the frequency information is within the second frequency band range, the scheduling module 425 of the second signal processing device 420 schedules the Ethernet data received from the interface module 424 to the second baseband module 422. In the process 1000 in FIG. 10, it is assumed that the scheduling module 425 schedules the Ethernet data to the second baseband module 422.

[0209] In operation 1060, the second baseband module 422 of the second signal processing device 420 processes the Ethernet data. Specifically, for example, the second split mode is option 7-1, and the second baseband module 422 may perform a series of operations on the data, such as port reduction, RE de-mapping, ..., and decoding.

[0210] In this manner, in an embodiment of the present disclosure, uplink data from the antenna module 415 can be scheduled by the scheduling module 412 to the first processing module 413 or the second processing module 414 based on the transmission configuration information.
