Description

Technical Field

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

Background Art

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

[0003] To meet the requirements of various services, operators need to provide access network devices that support both the first frequency band range and the second frequency band range. Currently, operators deploy both RRU and AAU to achieve this goal. However, since the RRU and AAU need to be installed separately, the complexity increases and the hardware cost becomes excessively high.

Summary of the Invention

[0004] Embodiments of the present disclosure provide a solution for data transmission. The first signal processing device can support two different splitting modes simultaneously, so that it can support the first frequency band range and the second frequency band range simultaneously. In this way, the first signal processing device can be used to meet the requirements of various services. This can reduce the complexity of deployment and cut costs.

[0005] A first aspect of this disclosure provides a first signal processing device. The first signal processing device includes: an interface module configured to perform Ethernet data transmission with a second signal processing device via optical fiber; a scheduling module configured to schedule data to be processed to the first processing module or the second processing module based on transmission configuration information from the second signal processing device, wherein the data to be processed includes Ethernet data from the second signal processing device or uplink data from an antenna module; a first processing module configured to process data from the scheduling module according to a first split mode; a second processing module configured to process data from the scheduling module according to a second split mode; and an antenna module configured to transmit processed data from the first processing module or the second processing module and / or receive uplink data.

[0006] In this way, the first signal processing device can process data separately according to a first division mode and a second division mode based on scheduling. It can be understood that the first signal processing device can support two different division modes simultaneously, thereby meeting the requirements of various services. In this way, there is no need to deploy RRUs and AAUs separately, thereby reducing complexity and cost.

[0007] In some possible implementations, the scheduling module is coupled to the interface module, antenna module, first processing module, and second processing module. In this way, the scheduling module can schedule data from the interface module or antenna module to the first processing module or second processing module, and implement correct data distribution.

[0008] In some possible implementations, the first division mode is a time-domain division mode, and the first processing module is configured to perform radio frequency (RF) processing on data from the scheduling module. Optionally, the first division mode may indicate that physical layer processing is performed by the first baseband module in the second signal processing device, and radio frequency processing is performed by the first processing module in the first signal processing device. Optionally, the first division mode may be a division mode that supports CPRI. In this way, the first signal processing device can support CPRI data processing.

[0009] In some possible implementations, the first processing module includes: a conversion submodule configured to implement the conversion between Ethernet data and time-domain data; and a beamforming submodule configured to implement the conversion between a first quantity of multi-channel first time-domain data and a second quantity of multi-channel second time-domain data, where the second quantity corresponds to the number of antenna channels in the antenna module, and the first quantity is less than the second quantity.

[0010] In this way, the first processing module can convert Ethernet data into time-domain data, thereby enabling beamforming to be performed in the time domain and ensuring correct data processing.

[0011] In some possible implementations, the data to be processed includes Ethernet data from a second signal processing device, and the number of antenna channels corresponding to the Ethernet data is a first quantity. The conversion submodule is configured to determine the corresponding multi-channel first time-domain data based on the Ethernet data. The beamforming submodule is configured to determine multi-channel second time-domain data based on the multi-channel first time-domain data and a second quantity of multiple first antenna weight parameters.

[0012] In this way, for downlink transmission, time-domain data can be recovered from Ethernet data from the second signal processing device, and beamforming can be performed in the time domain, thereby enabling the first signal processing device to support time-domain division mode and further support data processing in the first frequency band range.

[0013] In some possible implementations, the first processing module is coupled to an antenna module, which is configured to transmit multi-channel second time-domain data over multiple antenna channels. In this way, MIMO transmission can be implemented by fully utilizing the characteristics of multiple antennas through transmission over multiple antenna channels.

[0014] In some possible implementations, the conversion submodule is configured to determine multi-channel first time-domain data based on the partitioning of the Ethernet data payload. In this way, the corresponding time-domain data is obtained by partitioning the Ethernet data payload, thereby enabling subsequent time-domain processing to be performed on the time-domain data.

[0020] In some possible implementations, the number of multiple chips is determined based on at least one of the following factors: the first quantity, the number of sampling points in at least one of the multiple chips, the bit width of the sampling points, or the bandwidth. In this way, various factors can be fully considered during packet assembly, transmission bandwidth is fully utilized, transmission efficiency is increased, and wasted bandwidth resources are avoided.

[0021] In some possible implementations, the interface module is further configured to obtain from the second signal processing device at least one of the following: a first quantity, a second quantity, a second quantity of multiple first antenna weight parameters, or a second quantity of multiple second antenna weight parameters.

[0024] In this way, the first and second processing modules can each process different frequency bands, ensuring correct data processing. Thus, the first signal processing device can simultaneously support both the first and second frequency band ranges, avoiding the need to deploy separate devices for each frequency band range and reducing hardware costs.

[0025] In some possible implementations, the scheduling module is configured to: schedule data to be processed to a first processing module if the data falls within a first frequency band range; or schedule data to be processed to a second processing module if the data falls within a second frequency band range. In this way, the scheduling module can schedule data based on frequency band ranges to ensure that the first and second processing modules process data within their respective frequency band ranges and that correct data processing is ensured. In this manner, different carriers can be transmitted over the same optical fiber, and the scheduling module can implement distribution and scheduling to two different processing modules.

[0026] In some possible implementations, the second splitting mode is a splitting mode within the physical layer. Optionally, the splitting mode within the physical layer may indicate that data in the lower physical layer is processed by a second processing module in the first signal processing device, and data in the upper physical layer is processed by a second baseband module in the second signal processing device.

For example, terminal equipment may include mobile phones, stations, units, devices, mobile terminals (MT), subscriber stations, mobile subscriber stations, internet nodes, communication devices, desktop computers, laptop computers, notebook computers, tablet computers, personal communication system equipment, personal navigation equipment, personal digital assistants (PDAs), positioning equipment, radio broadcast receivers, e-book readers, game consoles, Internet of Things (IoT) devices, in-vehicle equipment, aircraft, virtual reality (VR) devices, augmented reality (AR) devices, wearable devices, terminal equipment in a 5G network, any terminal equipment in an evolved public land mobile network (PLMN), other devices that can be used for communication, or any combination thereof. This is not limited to the embodiments of this disclosure.

[0105] In this disclosure, the term “network equipment” refers to an entity or node, which may be, for example, an access network device that can be configured to communicate with terminal equipment. Access network equipment may be a device, for example, a radio access network (RAN) network device deployed in a radio access network to provide radio communication capabilities to mobile terminals. Access network equipment may include various types of base stations. For example, 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 similar. In systems using different radio access technologies, the names of access network equipment may also differ. For example, access network equipment may be called evolved NodeB (eNB, or eNodeB) in Long Term Evolution (LTE) networks, NodeB (NodeB, NB) in 3G networks, and gNodeB (gNB) or NR NodeB (NR NB) in 5G networks. In some scenarios, access network equipment may include a Central Unit (CU) and / or Distributed Unit (DU). The CU and DU may be located in different locations. For example, the DU may be located in a remote location in a high-traffic area, while 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 within a rack. For ease of explanation, in the following embodiments of this disclosure, the above-described equipment that provides wireless communication functionality to terminal equipment is collectively referred to as network equipment. This is not particularly limited in the embodiments of this disclosure.

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

[0107] Figure 1 is a schematic block diagram showing a distributed access network device 100. In Figure 1, the distributed access network device 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 that it can communicate with terminal equipment 140.

[0108] The optical fiber 130 in Figure 1 may be a cable related to the Common Public Radio Interface (CPRI) protocol. The CPRI protocol is one of the current standard radio interface protocols used to connect BBUs and RRUs. 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 RRU120 may include four modules: a digital intermediate frequency module, a transceiver module, a power amplification module, and a filtering module. A downlink transmission from a distributed access network device 100 to a terminal device 140 is used as an example. The digital intermediate frequency module may be configured to perform modulation and demodulation, digital upconversion and downconversion, analog / digital (A / D) conversion, and similar functions during optical transmission. The transceiver module is configured to implement the conversion from the intermediate frequency signal to a radio frequency signal. The converted radio frequency signal can then pass through the power amplification module and the filtering module and be transmitted to the terminal device 140 via the antenna 102.

[0110] In the distributed access network device 100 shown in Figure 1, a time-domain partitioning mode is used. In other words, the BBU 110 completes the processing at the Media Access Control (MAC) layer, the physical layer, and similar levels, while the RRU 120 completes the radio frequency (RF) processing. Furthermore, the carriers supported by the RRU 120 are within a first frequency band range, such as the 1.8 GHz frequency band.

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

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

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

[0114] Refer to Figure 3, using Option 7-1 as an example. Specifically, for downlink transmission, the BBU performs coding, rate matching, scrambling, modulation, layer mapping, precoding, resource element (RE) mapping, beamforming (BF) port expansion, and similar operations in the upper physical layer, while the AAU performs inverse Fast Fourier Transform (iFFT), cyclic prefix (CP) addition, and similar operations in the lower physical layer. For uplink transmission, the AAU performs CP removal and Fast Fourier Transform (FFT) in the lower physical layer, while the BBU performs port reduction, RE demapping, channel estimation, diversity synthesis, leveling, inverse discrete Fourier Transform (iDFT), demodulation, descrambling, rate matching dematching, decoding, and similar operations in the upper physical layer. Options 7-2 and 7-3 may be described with reference to Figure 3 and are not described herein.

[0115] For example, see the description in Section 4.2 of 3GPP TS 38.816 (e.g., 15.0.0) for Options 7-1, 7-2, and 7-3. See the description in Section 11.1.2.8 of 3GPP TS 38.801 (e.g., 14.0.0). However, it should be noted that the partition scheme shown in Figure 3 is merely an example and should not be construed as a limitation to embodiments of this disclosure.

[0116] Furthermore, the partitioning modes in this disclosure may also be understood to be referred to as partitioning schemes, protocol partitioning modes, or similar. In some scenarios, a partitioning mode may represent a partition into RRUs and BBUs, or a partition into AAUs and BBUs. For example, if a BBU includes CUs and DUs, a partitioning scheme may represent a partition into AAUs and DUs.

[0117] As described above, the RRU is connected to the BBU via the CPRI interface and supports the first frequency band range. The AAU is connected to the BBU via the eCPRI interface and supports the second frequency band range. To meet the requirements of different services, operators need to provide access network equipment that supports both the first and second frequency band ranges simultaneously. Deploying RRUs and BBUs separately not only results in a complex configuration but also incurs high costs.

[0118] Due to the problems described above, and other potential problems in similar scenarios, embodiments of the present disclosure provide a signal processing device. This signal processing device may be connected to a second signal processing device via optical fiber and can support two different split modes, namely 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 installation costs can be reduced. Embodiments of the present disclosure will be described in detail below with reference to Figures 4 to 11. Embodiments of the present disclosure may be further applicable to other scenarios, not limited to the BBU and RRU scenario, and the BBU and AAU scenario.

[0119] Figure 4 is a schematic block diagram showing an access network device 400 according to an embodiment of the present disclosure. The access network device 400 includes a first signal processing device 410 and a second signal processing device 420, the first signal processing device 410 being connected to the second signal processing device 420 via an optical fiber 430.

[0120] In some embodiments, the first signal processing device 410 may be installed outdoors, for example, on a pole, and the second signal processing device 420 may be installed inside a building.

The first signal processing device 410 and the second signal processing device 420 may transmit Ethernet data to each other. For example, for downlink transmission, the second signal processing device 420 transmits downlink Ethernet data to the first signal processing device 410. For example, for uplink transmission, the first signal processing device 410 transmits uplink Ethernet data to the second signal processing device 420.

[0121] As shown in Figure 4, the first signal processing device 410 may include an interface module 411, a scheduling module 412, a first processing module 413, a second processing module 414, and an antenna module 415.

The scheduling module 412 may be configured to schedule data to be processed to the first processing module 413 or the second processing module 414 based on transmission configuration information from the second signal processing device 420. The first processing module 413 may be configured to process data from the scheduling module 412 according to a first division mode. The second processing module 414 may be configured to process data from the scheduling module 412 according to a second division mode. The antenna module 415 may be configured to transmit downlink data and / or receive uplink data, the downlink data being processed data from the first processing module 413 or the second processing module 414. Specifically, the data to be processed scheduled by the scheduling module 412 may be Ethernet data from the interface module 411 or uplink data from the antenna module 415.

[0122] In some embodiments of this disclosure, the scheduling module 412 may include a first scheduling submodule and a second scheduling submodule. Figure 5 is another schematic block diagram showing a first signal processing device 410 according to some embodiments of this disclosure. As shown in Figure 5, the interface module 411 is connected to the first scheduling submodule 510, which in turn is connected to the first processing module 413 and the second processing module 414. The antenna module 415 is connected to the second scheduling submodule 520, which in turn is connected to the first processing module 413 and the second processing module 414.

[0123] The first scheduling submodule 510 may be configured to schedule Ethernet data from the interface module 411 to the first processing module 413 or the second processing module 414 based on transmission configuration information from the second signal processing equipment 420. 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 transmission configuration information from the second signal processing equipment 420. Optionally, the first scheduling submodule 510 may be further configured to transmit processed data from the first processing module 413 or the second processing module 414 to the interface module 411. 520 It may be further configured to transmit the processed data from the first processing module 413 or the second processing module 414 to the antenna module 415.

[0124] As shown in Figure 5, the first processing module 413 may include a conversion submodule 530 and a beamforming submodule 540, the conversion submodule 530 being connected to the beamforming submodule 540. The conversion submodule 530 may be configured to implement conversion between Ethernet data and time-domain data. The beamforming submodule 540 may be configured to implement 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 enumerated values ​​for the first and second quantities in this disclosure are merely examples and should not be construed as limitations on embodiments of this disclosure.

[0125] In some examples, the conversion submodule 530 that implements the conversion function may be understood to be referred to as a data bridge or by another name. This is not limited to the present disclosure. In embodiments of the present disclosure, the scheduling module 412 may be configured by the control plane (not shown) of a first signal processing device 410, for example, according to a splitting mode corresponding to different carriers.

[0126] In some embodiments of this disclosure, the first signal processing unit 410 can be obtained by upgrading and reconfiguring the AAU220 shown in Figure 2. For example, based on the AAU220 shown in Figure 2, the AAU220 is upgraded to the first signal processing unit 410 by adding a scheduling module 412 and a first processing module 413. In this way, existing equipment can be fully utilized, thereby avoiding large-scale equipment replacement and further reducing costs.

[0127] As shown in Figure 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 conversions between time-domain data and Ethernet data. The interface module 424 may be configured to perform Ethernet data transmission to the first signal processing device 410 via the optical fiber 430. Specifically, the conversion module 423 may convert time-domain data from the first baseband module 421 to Ethernet data and convert Ethernet data from the interface module 424 to time-domain data.

[0128] Optionally, the second signal processing device 420 may further include a scheduling module 425. The scheduling module 425 may be connected to the conversion module 423 and the second baseband module 422, and the scheduling module 425 may also be connected to the interface module 424. 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, the conversion module 423 implementing the conversion function may be understood to be referred to as a data bridge or by another name. This is not limited to this disclosure. In some examples, the scheduling module 425 may implement an Ethernet data distribution function, and accordingly, the scheduling module 425 may be understood to be referred to as a distribution module. This is not limited to this disclosure.

[0130] In some embodiments of this disclosure, the second signal processing unit 420 can be obtained by upgrading and rebuilding the BBU 110 shown in Figure 1 or the BBU 210 shown in Figure 2. For example, based on the BBU 110 shown in Figure 1, the BBU 110 is upgraded to the second signal processing unit 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 Figure 2, the BBU 210 is the second two Baseband module 422 The device is then upgraded to a second signal processing unit 420 by adding a conversion module 423. In this way, the existing equipment can be fully utilized, thereby avoiding large-scale equipment replacement and further reducing costs.

[0131] A transmission transmitted 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] Figures 4 and 5 show that the first signal processing unit 410 includes multiple modules and the second signal processing unit 420 includes multiple modules, but it should be noted that the modules in Figure 4 or Figure 5 are merely examples. In actual scenarios, the first signal processing unit 410 and the second signal processing unit 420 may include fewer modules or more joules. For example, the antenna module 415 may be independent of the first signal processing unit 410, in other words, the first signal processing unit 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 this disclosure are illustrative and merely represent a logical functional division. Other division methods are possible in actual implementations. Furthermore, the functional units in the embodiments of this disclosure may be integrated into a single unit, or each functional unit may exist physically independently, or two or more units may be integrated into a single unit. The integrated unit may be implemented in hardware form or in the form of a software functional unit.

[0134] Hereinafter, several embodiments of this disclosure will be described in more detail with reference to the signaling interaction diagrams shown in Figures 6 to 8.

[0135] Figure 6 is a signaling interaction diagram showing a data transmission process 600 according to several embodiments of the present disclosure. Figure 6 relates to a first signal processing device 410 and a second signal processing device 420, where 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 time-domain data by performing a series of operations such as coding, rate matching, ..., and CP addition.

[0137] Furthermore, time-domain data may also be referred to as in-phase / quadrature (I / Q) data, or baseband quadrature sampled data, or CPRI data, or by another name. This is not limited to the foregoing. Optionally, the time-domain data generated by the first baseband module 421 may be digital baseband data acquired 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 quantity 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 the first quantity, such as any value among 1, 2, 4, or 8.

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

[0140] In the example described above, the chip contains 15 sampling points, but embodiments of the present disclosure are not limited to these. For example, the number of sampling points included in the chip may be equal to 8, or it may be equal to another value. Furthermore, the “sampling points” described above may also be referred to as words, other names, or similar terms, which are not limited to the present disclosure.

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

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

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

[0144] In some embodiments, the conversion module 423 can sequentially concatenate chips in time-domain data and use the concatenated data as an Ethernet data payload. Figure 7 is a schematic diagram showing 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 Figure 7, the basic unit of 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 optionally also include padding 725. For example, packet assembly may be performed on multiple chips 7122, and the multiple chips 7122 may be used as the payload 724 of the Ethernet data 720.

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

[0147] For example, suppose the bandwidth is 20 MHz, the Maximum Transmission Unit (MTU) of Ethernet data corresponding to this bandwidth is 1500 bytes, and the packet header length is 64 bytes. Assume the first quantity is equal to 4, the number of sampling points in a chip is equal to 8, and the bit width of a sampling point is equal to 15. In one example, the quantity of multiple chips can be determined by truncating (1500-64) / (4×8×15×2 / 8), which is 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 should be understood that the above-described method for determining the quantity of multiple chips is merely an example. In actual scenarios, the quantity of multiple chips may be equal to a different value, for example, a value less than the quantity determined by the above-described method, such as 10 or 9. This is not limited to the present disclosure.

[0149] In operation 630, the interface module 424 of the second signal processing device 420 transmits Ethernet data to the first signal processing device 410 via the optical fiber 430. Accordingly, the interface module 411 of the first signal processing device 410 can receive 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 Ethernet data to the first processing module 413 based on the transmission configuration information.

[0151] In some embodiments of this disclosure, transmission configuration information may be pre-transmitted to the first signal processing device 410 by a second signal processing device 420. See Figure 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. Accordingly, 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 instruction information indicating whether or not processing is performed by the first processing module 413. For example, the instruction information may be understood as a switch used by the first processing module 413 to process the data, and may be, for example, 1 or 0. The instruction information may also be understood to be in a different form, and is not limited to this 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 Ethernet data received from the interface module 411 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 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 the correspondence between a first frequency band range and a first processing module 413, and the second instruction information indicates the correspondence between a second frequency band range and a second processing module 414. For example, a specific field of Ethernet data received from 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 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 interface module 411 to the second processing module 414.

[0154] It should be noted that the transmission configuration information in the embodiments of this disclosure may alternatively include other instruction forms, thereby allowing the scheduling module 412 to decide, based on the transmission configuration information, to schedule Ethernet data from the interface module 411 to a first processing module 413 or a second processing module 414. In process 600 in Figure 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 Ethernet data from the scheduling module 412 according to the first partitioning mode. The first partitioning mode may be a time-domain partitioning mode. Optionally, the first partitioning mode may be a partitioning mode that supports the CPRI protocol. Referring to Figure 3, the first partitioning mode may be option 8 shown in Figure 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] Refer to Figure 6. In operation 650, the conversion submodule 530 converts Ethernet data into time-domain data. Specifically, the conversion submodule 530 can convert Ethernet data into a first quantity of multi-channel first time-domain data.

[0157] In some embodiments of this disclosure, the first quantity may be pre-configured for the first signaling device 410 by the second signaling device 420. 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, and for example, the second signaling device 420 may notify the first signaling device 410 of the first quantity based on a different part of separate signaling.

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

[0159] The beamforming submodule 540 converts the first quantity of multichannel first time-domain data into a second quantity of multichannel second time-domain data, where the second quantity exceeds the first quantity.

[0160] Specifically, the beamforming submodule 540 can 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 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 expressed as N1, the second quantity may be expressed 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 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 can be duplicated to obtain 8 copies, thus obtaining 32 channel time-domain data. For example, the 1st to 8th channel time-domain data in the 32 channel time-domain data is the 1st channel first time-domain data in the N1 channel first time-domain data, the 9th to 16th channel time-domain data in the 32 channel time-domain data is the 2nd channel first time-domain data in the N1 channel first time-domain data, the 17th to 24th channel time-domain data in the 32 channel time-domain data is the 3rd channel first time-domain data in the N1 channel first time-domain data, and the 25th to 32nd channel time-domain data in the 32 channel time-domain data is the 4th channel first time-domain data in the N1 channel first time-domain data. Optionally, a plurality of first antenna weight parameters are a second quantity of a plurality of first antenna weight parameters, and these plurality of first antenna weight parameters can be represented sequentially as wt1, wt2, ..., and wtN2. In this way, the i-th channel time-domain data in 32 channel time-domain data can be multiplied by wti (where i = 1, 2, ..., N2) to obtain the i-th channel second time-domain data in N2 channel second time-domain data.

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

[0165] It should be noted that the data processing processes performed by the first processing module 413 described in the embodiments of this disclosure are merely examples. In actual scenarios, other processes such as power amplification and filtering may be included.

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

[0167] In this way, the conversion module 423 of the second signal processing device 420 in the embodiments of the present disclosure can convert time-domain data into Ethernet data, thereby enabling the Ethernet data to be transmitted to the first signal processing device 410 via eCPRI optical fiber. In this way, 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] Figure 8 is a signaling interaction diagram showing a data transmission process 800 according to several embodiments of the present disclosure. Figure 8 relates to a first signal processing device 410 and a second signal processing device 420, where 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 Ethernet data to the first signal processing device 410 via the optical fiber 430. Accordingly, the interface module 411 of the first signal processing device 410 can receive 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 Ethernet data to the second processing module 414 based on the transmission configuration information.

[0172] In some embodiments of this disclosure, transmission configuration information may be pre-transmitted to the first signaling device 410 by the second signaling device 420. See Figure 8. In operation 801, the interface module 424 of the second signaling device 420 transmits the transmission configuration information to the first signaling device 410. Accordingly, the interface module 411 of the first signaling device 410 may receive the transmission configuration information. For details of the transmission configuration information, see the embodiment described with reference to operation 601 in Figure 6. For brevity, details are not described herein.

[0173] In operation 840, the second processing module 414 processes the Ethernet data from the scheduling module 412 according to the second partitioning mode. The second partitioning mode may be an internal physical layer partitioning mode. Optionally, the second partitioning mode may be a partitioning mode that supports the eCPRI protocol. Referring to Figure 3, the second partitioning mode may be option 7-1, option 7-2, or option 7-3 as shown in Figure 3. For example, the second processing module 414 performs lower physical layer processing and RF processing on the Ethernet data, but does not perform higher 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 processes performed by the second processing module 414 described in embodiments of this disclosure are merely examples. In actual scenarios, processing processes may include, for example, frequency-domain beamforming, power amplification, and filtering. For specific operations performed by the second processing module 414 in some examples, refer to the operations performed by AAUs 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 embodiments of the present disclosure generates Ethernet data, which can then 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] Figure 9 is a signaling interaction diagram showing a data transmission process 900 according to several embodiments of the present disclosure. Figure 9 relates to a first signal processing device 410 and a second signal processing device 420, where 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 terminal equipment. Optionally, a second quantity of antenna channels in the antenna module 415 may receive multi-channel data, which is called, for example, a second quantity of multi-channel second time-domain data.

[0179] In 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 this disclosure, transmission configuration information may be pre-transmitted to the first signal processing device 410 by the second signal processing device 420. See Figure 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. Accordingly, 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 or not processing is performed by the first processing module 413. For example, the instruction information may be understood as a switch used by the first processing module 413 to process the data, and may be, for example, 1 or 0. The instruction information may be understood to be in an alternative form, and is not limited to this 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 the correspondence between a first frequency band range and a first processing module 413, and the second instruction information indicates the correspondence between a second frequency band range and a second processing module 414. For example, a specific field of 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 embodiments of this disclosure may alternatively include other instruction forms, thereby allowing the scheduling module 412 to decide, based on the transmission configuration information, to schedule the uplink data received from the antenna module 415 to either the first processing module 413 or the second processing module 414. In process 900 in Figure 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 the first division mode. The first division mode may be a time-domain division mode. Optionally, the first division mode may be a division mode that supports the CPRI protocol. Referring to Figure 3, the first division mode may be option 8 shown in Figure 3. For example, the first processing module 413 performs RF processing on the uplink data but does not perform physical layer processing.

[0185] Refer to Figure 9. In operation 930, the beamforming submodule 540 converts the uplink data into a first quantity of multi-channel first time-domain data, where the first quantity is less than the second quantity.

[0186] In some embodiments of this disclosure, the first quantity may be pre-configured for the first signaling device 410 by the second signaling device 420. 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, and for example, the second signaling device 420 may notify the first signaling device 410 of the first quantity based on a different part of separate signaling.

[0187] The beamforming submodule 540 can 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 submodule 540 can 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, the plurality of second antenna weight parameters can 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 can include the plurality of second antenna weight parameters. In some other embodiments, the plurality of second antenna weight parameters can be independent of the transmission configuration information. For example, the second signal processing device 420 can notify the first signal processing device 410 of the plurality of second antenna weight parameters based on another part of separate signaling.

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

[0190] For example, assume N1=4 and N2=32. Optionally, multiple second antenna weight parameters are second quantities of multiple second antenna weight parameters, and these multiple second antenna weight parameters can be represented sequentially as wr1, wr2, ..., and wrN2. The i-th channel second time-domain data in the N2 channel second time-domain data can be multiplied by wri(i=1, 2, ..., N2) to obtain the i-th channel time-domain data in the N2 channel time-domain data. Next, the first channel time-domain data in the N2 channel time-domain data to the eighth channel time-domain data in the N2 channel time-domain data can be combined (e.g., countable) to obtain the first channel first time-domain data in the N1 channel first time-domain data, and the ninth channel time-domain data to the sixteenth channel time-domain data in the N2 channel time-domain data can be combined (e.g., countable) to obtain the second channel first time-domain data in the N1 channel first time-domain data, and the seventeenth channel time-domain data to the twenty-fourth channel in the N2 channel time-domain data Time-domain data This can be combined (e.g., countably) to obtain the third channel in the first time-domain data of the N1 channel, and the 25th channel in the N2 channel time-domain data. Time-domain data Alternatively, the 32nd channel time-domain data within the N2 channel time-domain data can be joined (e.g., countable) to obtain the 4th channel first time-domain data within the N1 channel first time-domain data.

[0191] It should be noted that the data processing processes performed by the first processing module 413 described in the embodiments of this disclosure are merely examples. In actual scenarios, other processes such as power amplification and filtering may be included.

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

[0193] In operation 950, the interface module 411 of the first signal processing device 410 transmits Ethernet data to the second signal processing device 420. Accordingly, the interface module 424 of the second signal processing device 420 can receive 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 Ethernet data to the conversion module 423. Specifically, the scheduling module 425 may perform scheduling based on the 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 process 900 in Figure 9, it is assumed that the scheduling module 425 schedules Ethernet data to the conversion module 423.

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

[0196] The conversion module 423 can determine a corresponding first quantity of multi-channel first time-domain data based on the division of the Ethernet data payload. The Ethernet payload may be an eCPRI payload. The conversion module 423 can divide the payload based on the chip size, add control words to the chip, and 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 time-domain data. Specifically, the first baseband module 421 may process time-domain data by performing a series of operations such as CP rejection, FFT, ..., and decoding.

[0198] Figure 10 is a signaling interaction diagram showing a data transmission process 1000 according to several embodiments of the present disclosure. Figure 10 relates to a first signal processing device 410 and a second signal processing device 420, where process 1000 is an uplink transmission from the first signal processing device 410 to the second signal processing device 420.

[0199] In operation 1010, the antenna module 415 of the first signal processing device 410 receives uplink data.

[0200] In operation 1020, the scheduling module 412 of the first signal processing device 410 schedules the uplink data to the second processing module 414 based on the transmission configuration information.

[0201] In some embodiments of this disclosure, transmission configuration information may be pre-transmitted to the first signal processing device 410 by a second signal processing device 420. See Figure 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. Accordingly, 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 or not processing is performed by the first processing module 413. For example, the instruction information may be understood as a switch used by the first processing module 413 to process the data, and may be, for example, 1 or 0. The instruction information may be understood to be in an alternative form, and is not limited to this 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 the correspondence between a first frequency band range and a first processing module 413, and the second instruction information indicates the correspondence between a second frequency band range and a second processing module 414. For example, a specific field of 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 embodiments of this disclosure may alternatively include another instruction form, thereby allowing the scheduling module 412 to decide, based on the transmission configuration information, to schedule the uplink data received from the antenna module 415 to either the first processing module 413 or the second processing module 414. In process 1000 in Figure 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 the second division mode. The second division mode may be an internal physical layer division mode. Optionally, the second division mode may be a division mode that supports the eCPRI protocol. Referring to Figure 3, the second division mode may be option 7-1, option 7-2, or option 7-3 as shown in Figure 3. For example, the second processing module 414 performs lower physical layer processing and RF processing on the Ethernet data, but does not perform higher physical layer processing. For example, the second division mode is option 7-1. The processing performed by the second processing module 414 may include operations such as CP rejection and FFT.

[0206] It should be noted that the data processing processes performed by the second processing module 414 described in embodiments of this disclosure are merely examples. In actual scenarios, processing processes may include, for example, frequency-domain beamforming, power amplification, and filtering. For specific operations performed by the second processing module 414 in some examples, 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 Ethernet data to the second signal processing device 420. Accordingly, the interface module 424 of the second signal processing device 420 can receive 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 Ethernet data to the second baseband module 422. Specifically, the scheduling module 425 may perform scheduling based on the 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 process 1000 in Figure 10, it is assumed that the scheduling module 425 schedules 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 this data, such as port reduction, RE mapping demapping, ..., and decoding.

[0210] In this manner, in the embodiments of the present disclosure, uplink data from the antenna module 415 can be scheduled by the scheduling module 412 to a first processing module 413 or a second processing module 414 based on transmission configuration information. In this way, the first processing module 413 can process the uplink data according to a first division mode, and the second processing module 414 can process the uplink data according to a second division mode, thereby enabling simultaneous support of a first frequency band range and a second frequency band range.
