Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular to a 5G fronthaul interface message assembly method, device, electronic device and storage medium. Background Art

[0002] In the design and implementation of long time evolution (LTE) and 5G NR (New Radio), the baseband processing unit (Building Baseband Unite, BBU) and the remote radio unit (Remote Radio Unit, RRU) are usually split and connected by optical fiber. The remote radio unit brings a new distributed network coverage mode, which places large-capacity macro cell base stations in an available central machine room, centrally processes the baseband part, and uses optical fiber to pull the radio frequency module in the base station to the remote radio unit, which is placed at the site determined by the network planning, thus saving a large number of machine rooms required by conventional solutions.

[0003] At the same time, by using large-capacity macro base stations to support a large number of optical fiber extensions, the conversion between capacity and coverage can be achieved. The interface between the RRU and the BBU is called the fronthaul interface. There are two common protocols for the fronthaul interface, CPRI (common public radio interface) and eCPRI (evolved common public radio interface). The underlying carrier of the eCPRI protocol is Ethernet, MAC layer or TCP / IP layer. The eCPRI protocol is integrated into the TCP / IP protocol family. Compared with the proprietary nature of the CPRI protocol, the versatility of the eCPRI protocol has been greatly improved.

[0004] The universality of the eCPRI protocol allows the RRU to grow into an independent network element without relying on the BBU. The network management center can directly manage the RRU without relying on the BBU. The protocol between the BBU and the RRU can be standardized, providing architectural guarantees for the interconnection and interoperability of BBUs and RRUs from different manufacturers. And because the control field of eCPRI has a small amount of data and is not fixed in every message, its available bandwidth is larger. The O-RAN (OpenRadio Access Network) protocol is a specific implementation form of eCPRI, which defines the specific usage details of the fronthaul interface in detail, which makes the fronthaul interface implemented using O-RAN have good adaptability.

[0005] eCPRI and O-RAN protocols work on the fronthaul interface, which has real-time requirements, which cannot be achieved by traditional high-speed network processors. Moreover, the hardware devices that can currently support eCPRI and O-RAN are usually implemented by FAGA. FAGA is more flexible and can be continuously updated according to protocol changes to meet the transmission requirements of the interface; however, FAGA is costly and has a slow processing speed, and can only support relatively small data throughput. If it is implemented using an application-specific integrated circuit (ASIC), it is difficult to cope with protocol upgrades and updates. Summary of the invention

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Figure 1 A schematic diagram of a 5G fronthaul interface message assembly method provided in an embodiment of the present invention is shown in FIG. Figure 1 As shown, the method includes: S1, receiving various service data sent by the uplink U-plane link; S2, compressing each business data based on the target bit width of each business data while keeping the original bit width corresponding to each business data unchanged, to obtain compressed data of each business data; S3, removing redundant bits in the compressed data of each service data, and rearranging the remaining data of each service data to obtain arranged data; S4, based on the first network processor, encapsulating the arranged data into a 5G fronthaul interface message, storing the 5G fronthaul interface message into a first cache, and storing address information of the 5G fronthaul interface message into a second cache; S5, receiving a timing signal sent by the uplink U-plane link; S6, based on the second network processor and taking the timing signal as a reference, reading the message address information from the second cache; S7, based on the message address information, reading the target message from the first cache, and sending the target message to the Ethernet switch; Among them, the first network processor and the second network processor are both programmable processors that support the transmission protocol of the 5G fronthaul interface.

[0026] Specifically, the 5G fronthaul interface message assembly method provided in the embodiment of the present invention is executed by a 5G fronthaul interface message assembly device, which can be applied to the sending end of the 5G fronthaul interface and can realize real-time packet assembly of 5G fronthaul messages.

[0027] First, step S1 is executed to receive each service data sent by the uplink U-plane (user plane) link. The service data may include the phase and amplitude of different transmission signals. The phase is the imaginary part and the amplitude is the real part, which can constitute a complex symbol on the subcarrier, indicating the amount of data carried on the subcarrier, that is, the load. For example, if there are two transmission signals, each service data may include the phase Q0 and amplitude I0 of the first transmission signal, and the phase Q1 and amplitude I1 of the second transmission signal.

[0028] Then, step S2 is performed to compress each business data based on the target bit width of each business data while the original bit width corresponding to each business data remains unchanged, so as to obtain compressed data of any business data. Here, the target bit width of each business data is the business data bit width in the compressed data. By using the compression module, compressing a certain business data is equivalent to right-shifting the business data.

[0029] Since the original bit width corresponding to each service data remains unchanged, that is, the bit width of each service data and the compressed data remains unchanged, it is necessary to fill the left side of the service data with a sign bit. The sum of the bit width of the sign bit and the target bit width of the service data is equal to the original bit width corresponding to the service data.

[0030] For example, if the first transmission signal and the second transmission signal occupy 64 bits in total, Q0 occupies bits 0-15, I0 occupies bits 16-31, Q1 occupies bits 32-47, and I1 occupies bits 48-63.

[0031] After compressing Q0, I0, Q1, and I1, the corresponding compressed data Q0', I0', Q1', and I1' are obtained respectively. The left side of each compressed data is filled with a sign bit S, the sum of the bit widths of Q0' and S is equal to the bit width of Q0, the sum of the bit widths of I0' and S is equal to the bit width of I0, the sum of the bit widths of Q1' and S is equal to the bit width of Q1, and the sum of the bit widths of I1' and S is equal to the bit width of I1.

[0032] Then, step S3 is executed to remove the redundant bits in the compressed data of each service data, which are the sign bits in the compressed data. The remaining data are the service data in the compressed data, and the remaining data are rearranged to obtain the arranged data. The arranged data is obtained by compressing the service data with the sign bits filled in and rearranging.

[0033] like Figure 2 The figure shows a data format diagram of business data, compressed data and arranged data.

[0034] Thereafter, step S4 is executed, and the arranged data is encapsulated into a 5G fronthaul interface message using the first network processor, and the 5G fronthaul interface message is stored in the first cache, and the address information of the 5G fronthaul interface message is stored in the second cache. Here, the address information of the 5G fronthaul interface message can be the address information of the 5G fronthaul interface message in the first cache, and the address information can be recorded in the second cache in the form of a linked list. It can be understood that the address information is the control information of the 5G fronthaul interface message.

[0035] It is understandable that the first network processor is a programmable processor that supports the transmission protocol of the 5G fronthaul interface, and may be an application specific instruction set processor (ASIP). The transmission protocol may include, but is not limited to, the CPRI protocol, the eCPRI protocol, and the O-RAN protocol, and may also be a new protocol applicable to the 5G fronthaul interface, which is not specifically limited here. The transmission protocol supported by the first network processor may be updated and upgraded through programming.

[0036] After storing the 5G fronthaul interface message into the first cache and storing the address information of the 5G fronthaul interface message into the second cache, step S5 can also be executed to receive the timing signal sent by the uplink U-plane link, that is, the uplink U-plane link will not only send various service data, but also send a timing signal, which is used to indicate the time to send data to the Ethernet switch.

[0037] Thereafter, step S6 may be executed, using the second network processor to read the message address information from the second cache according to the timing signal. It is understandable that the second network processor may also be a programmable processor supporting the transmission protocol of the 5G fronthaul interface, which may be an ASIP. The transmission protocol supported by the second network processor may be updated and upgraded through programming.

[0038] Finally, step S7 is executed, the second network processor uses the message address information to read the target message from the first cache, and sends the target message to the Ethernet switch.

[0039] The 5G fronthaul interface message assembly method provided in the embodiment of the present invention first receives each service data sent by the uplink U-plane link; then, while the original bit width corresponding to each service data remains unchanged, each service data is compressed based on the target bit width of each service data to obtain compressed data of each service data; thereafter, the redundant bits in the compressed data of each service data are removed, and the remaining data of each service data is rearranged to obtain arranged data; based on the first network processor, the arranged data is encapsulated into a 5G fronthaul interface message, and the 5G fronthaul interface message is stored in a first cache, and the address information of the 5G fronthaul interface message is stored in a second cache; thereafter, a timing signal sent by the uplink U-plane link can be received; based on the second network processor, the message address information is read from the second cache with the timing signal as a reference; based on the message address information, the target message is read from the first cache, and the target message is sent to the Ethernet switch. This method can realize data processing at the CPRI / eCPRI / O-RAN application layer by compressing and rearranging the service data, which can not only save bandwidth, but also improve the data rate of 5G fronthaul and ensure the real-time performance of the fronthaul interface. The 5G fronthaul interface message is first saved by the first cache and the second cache, and then the 5G fronthaul interface message is sent according to the timing signal, which can meet the timing requirements. Moreover, the first network processor and the second network processor are both programmable processors that support the transmission protocol of the 5G fronthaul interface, which can be flexibly configured for data encapsulation storage and message reading and sending, with low silicon overhead and high flexibility, which can adapt to the continuous upgrading of the transmission protocol of the 5G fronthaul interface and meet user customization requirements. In addition, this method adopts a stream processing architecture and data pipeline processing for the processing of user plane data, and the processing flux is large enough to improve the throughput of the system.

[0040] On the basis of the above embodiment, the step of removing redundant bits in the compressed data of each service data and rearranging the remaining data of each service data to obtain arranged data includes: Based on the data arrangement module, redundant bits in the compressed data of each service data are removed, and the remaining data of each service data is rearranged to obtain the arranged data; Wherein, the data arrangement module is a programmable module that supports rearrangement of data with different bit widths.

[0041] Specifically, in the embodiment of the present invention, a data arrangement module may be used to remove redundant bits in the compressed data of each business data, and to rearrange the remaining data of each business data to obtain arranged data.

[0042] It is understandable that the data arrangement module is a programmable module that supports rearrangement of data of different bit widths, for example, it can support rearrangement of data of any bit width that is less than or equal to the original bit width. Data of any bit width can be rearranged through programming.

[0043] In an embodiment of the present invention, the data arrangement module is a programmable module that supports the rearrangement of data of different bit widths. It is flexibly configurable for the rearrangement of data of any bit width. It has low silicon overhead, can adapt to the continuous upgrading of the transmission protocol of the 5G fronthaul interface, and can also meet user customization requirements.

[0044] Based on the above embodiment, the first cache is a dual-port memory, which can simultaneously receive and read 5G fronthaul interface messages to improve service processing efficiency.

[0045] On the basis of the above embodiment, the method of compressing each service data based on the target bit width of each service data to obtain compressed data of each service data includes: Determine the target compression method; Based on the target bit width of each service data, the target compression method is applied to compress each service data to obtain compressed data of each service data.

[0046] Specifically, when compressing each service data, a target compression mode may be determined first, and the target compression mode may be one of A-law coding compression, μ-law coding compression or Block Float Point (BFP) compression.

[0047] Thereafter, each business data is compressed using the target bit width of each business data and applying the target compression method, thereby obtaining compressed data of each business data.

[0048] On the basis of the above embodiment, the method of encapsulating the arranged data into a 5G fronthaul interface message based on the first network processor includes: Based on the first network processor, applying the configuration information, generating a packet header, and performing length management on the arranged data to obtain a management result; The packet header and the management result are encapsulated to obtain the 5G fronthaul interface message.

[0049] Specifically, when the arranged data is encapsulated into a 5G fronthaul interface message, the first network processor can be used to apply the configuration information, and a packet header can be generated through insertion, replacement, etc. The configuration information is pre-configured and can include strategy information for generating the packet header.

[0050] Afterwards, the arranged data may be length-managed to obtain a management result, and the length of the management result may be a data length that meets the encapsulation requirements.

[0051] Finally, the packet header and the management result are encapsulated to obtain one or more 5G fronthaul interface messages in the form of data packets. The 5G fronthaul interface message may be an O-RAN message or an eCPRI message.

[0052] Based on the above embodiment, for the implementation of NR 30Khz subcarrier spacing 100Mhz full bandwidth, the interval of each symbol is 1 / 30K=33.33μs, each symbol has a maximum of 273 RBs, and each RB consists of 12 REs.

[0053] Table 1 Analysis of the method for processing NR 30K 100M

[0054] This method can support a maximum of 36 antenna packages.

[0055] In a 4-receive 4-transmit NR base station system, with a 30Khz subcarrier spacing and a 100Mhz bandwidth, the time interval between each symbol is 1 / 30K=33.33μs. Since there are four antennas, the processing time for each symbol of each antenna is 33.33μs / 4=8.3μs. If the 5G fronthaul interface is implemented at a main frequency of 0.5Ghz, it can be seen from Table 2 that this method can fully meet the usage requirements of the 5G fronthaul interface.

[0056] Table 2 The processing time required for this method to process NR 30K 100M 4 send and 4 receive

[0057] In a 4-receive 4-transmit LTE base station system, with a 15Khz subcarrier spacing and a 20Mhz bandwidth, the time interval between each symbol is 1 / 15K=66.67μs. Since there are four antennas, the processing time for each symbol of each antenna is 66.67μs / 4=16.67μs. If the 5G fronthaul interface is implemented at a main frequency of 0.5Ghz, it can be seen from Table 3 that this method can fully meet the usage requirements of the 5G fronthaul interface.

[0058] Table 3 Time requirements for processing LTE 15K 20M2 send and receive by this method

[0059] In summary, the 5G fronthaul interface message assembly method provided in the embodiment of the present invention can meet the needs of the transmitting end of the fronthaul interface that supports wireless communication, that is, it has the characteristics of high speed and large throughput, and can meet the average throughput of at least 10Gbps required by the fronthaul interface of the 5G NR 4-transmit 4-receive small base station, and has the ability to handle burst throughput of 60Gbps. Moreover, it has the ability of timed transmission, and the data synchronization of wireless communication is achieved through timing. The fronthaul interface has the required ability of real-time packet assembly and timed transmission. In addition, the 5G fronthaul interface supports data compression, and the compressed data is tightly arranged to save bandwidth.

[0060] like Figure 3 FIG. 1 is a schematic diagram of data flow of a 5G fronthaul interface message assembly method provided in an embodiment of the present invention. Figure 3 In the process, the uplink U-plane link sends each service data to the compression module and sends a timing signal to the second network processor. The compression module compresses each service data to obtain compressed data of each service data, and sends the compressed data to the data arrangement module. The redundant bits in the compressed data of each service data are removed by the data arrangement module, and the remaining data of each service data is rearranged to obtain the arranged data, and the arranged data is sent to the first network processor. The first network processor encapsulates the arranged data into a 5G fronthaul interface message, stores the 5G fronthaul interface message in the first cache, and stores the address information of the 5G fronthaul interface message in the second cache. The second network processor uses the timing signal as a reference, reads the message address information from the second cache, and based on the message address information, reads the target message from the first cache, and sends the target message to the Ethernet switch.

[0061] Figure 3 The data flow in shows that the processing of user plane data adopts a stream processing architecture and data pipeline processing. The processing flux is large enough to improve the throughput of the system.
