Description

[Technical Field]

[0001] This application relates to the field of communications technology, and more particularly to data processing in general. [Background technology]

[0002] In the field of communications, a terminal device transmits air interface data to a network device, and the network device performs data processing on the air interface data from the terminal device. Specifically, a distributed unit (DU) in the network device performs channel parsing and service identification on the air interface data, and then transfers corresponding service data in the air interface data to each processing module in the DU, and the processing module further processes the service data.

[0003] However, the above data processing methods are prone to high latency. For low-latency services, the latency caused by the above data processing methods has a significant impact on the low-latency requirements of the low-latency services. Therefore, there is an urgent need for a method that can reduce the overall latency of data processing. Summary of the Invention

[0004] The present application provides a data processing method and a communication device to reduce the overall latency of data processing.

[0005] According to a first aspect, there is provided a data processing method, which is applied to a module on a radio frequency unit side of a network device, for example, the radio frequency unit, or a software module, a hardware circuit, or a combination of a software module and a hardware circuit, capable of implementing the method, and which includes: determining first resource characteristics of first service data; and transmitting the first service data based on the first resource characteristics to a first processing module, the first processing module being one of at least one processing module used on a distributed unit side of the network device.

[0006] Specifically, the radio frequency unit may be a radio unit (RU) or a module having a radio frequency function, such as a remote radio unit (RRU) or an active antenna unit (AAU). Therefore, the radio frequency unit is a generic concept of the RU or the RRU. Furthermore, the distributed unit may be a distributed unit (DU) or another unit or module capable of performing similar or the same function. This is not a limitation of the present application. Therefore, the distributed unit is a generic concept of the DU.

[0007] Compared with the method in which the radio frequency unit transmits service data to the distributed unit, which then performs resource feature identification on the service data and forwards the service data to the corresponding processing module, the method in which the radio frequency unit performs resource feature identification on the service data and then transmits the corresponding service data to the processing module in the distributed unit can reduce the overall latency of data processing.

[0008] Furthermore, the radio frequency unit can transmit the corresponding service data to the processing module in the distribution unit, and the distribution unit no longer needs a module or integrated circuit configured to perform the service data distribution function. In this way, the overall cost of the network device can be reduced.

[0009] Based on the above technical solutions, the present application can further help reduce the complexity of data interaction between radio frequency units and distributed units of network devices.

[0010] In a possible implementation, the method further includes receiving first indication information indicating at least one mapping relationship, each mapping relationship being used to associate one resource feature with one processing module, and determining a first processing module based on the first mapping relationship and the first resource feature, wherein the at least one mapping relationship includes the first mapping relationship, and the first mapping relationship associates the first resource feature with the first processing module.

[0011] In this way, the radio frequency unit can obtain the mapping relationship between the processing modules of the distributed units and the resource characteristics of the service data by interacting with the distributed units, so that the radio frequency unit determines the resource characteristics of the service data, and then determines the processing modules associated with each service data based on the above mapping relationship.

[0012] In a possible implementation, the first indication information includes an identifier of at least one processing module and a resource characteristic associated with the processing module corresponding to each identifier.

[0013] Specifically, the distributed unit can transmit to the radio frequency unit identifiers of the processing modules in the distributed unit and resource characteristics associated with each processing module, so that the radio frequency unit can determine the corresponding processing module based on the resource characteristics of the service data.

[0016] Specifically, the radio frequency unit transmits the first service data to the first processing module only when the radio frequency unit determines that the first processing module is in an operational state based on the second indication information, which can improve the efficiency of data interaction between the radio frequency unit and the processing module in the distributed unit.

[0053] The network device in the embodiments of the present application may further include a network element or module that implements part of the functions of a base station, for example, one or more of the following: a central unit (CU), a distributed unit (DU), or a radio unit (RU). Optionally, the CU may be further divided into a CU control plane (CP) and a CU user plane (UP). The functions of the CU and DU may be implemented by different network elements, or both may be implemented by a base station baseband unit (BBU). The functions of the RU may be implemented by a radio frequency device of the base station. For example, the radio frequency device of the base station may be a remote radio processing unit (RRU), a remote radio head (RRH), a pico remote radio unit (pRRU), an active antenna processing unit (AAU), or other unit, module, or device with radio frequency processing functionality. The communication interface protocol between the BBU and the radio frequency device may be, but is not limited to, a common public radio interface (CPRI) interface protocol, an enhanced common public radio interface (eCPRI) interface protocol, a fronthaul interface protocol between a DU and an RU in an O-RAN system, etc. Optionally, the fronthaul interface protocol between a DU and an RU in an O-RAN system can further be considered as a specific example of the eCPRI interface protocol.

[0054] In embodiments of the present application, an apparatus configured to implement the functionality of a network device may be a network device itself, or may be an apparatus capable of helping a network device implement the functionality, such as a chip system. The apparatus may be implemented in a network or used in conjunction with a network device. In embodiments of the present application, the chip system may include a chip, or may include a chip and other discrete components.

[0055] FIG. 1 is a diagram of a communication system 100 to which an embodiment of the present application is applied. As shown in FIG. 1, the communication system 100 includes a radio access network (RAN) 10 and a core network (CN) 20. The RAN 10 includes at least one RAN node (e.g., 110a and 110b in FIG. 1 , collectively referred to as 110) and at least one terminal (e.g., 120a-120j in FIG. 1 , collectively referred to as 120). The RAN 10 may further include other RAN nodes, such as a wireless relay device and / or a wireless backhaul device (not shown in FIG. 1 ). The terminal 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to a core network 20 in a wireless or wired manner. The core network device in the core network 20 and the RAN node 110 in the RAN 10 may be different physical devices, or may be the same physical device incorporating the logical functions of a core network and a radio access network.

[0056] The RAN 10 may be a 3GPP-related cellular system, such as a 4G or 5G mobile communication system, or a future-oriented evolved system (e.g., a 6G mobile communication system). Alternatively, the RAN 10 may be an O-RAN or a CRAN. Alternatively, the RAN 10 may be a communication system incorporating two or more of the above systems.

[0057] The RAN node 110, sometimes referred to as an access network device, RAN entity, access node, etc., forms part of a communication system and helps terminals implement wireless access. Multiple RAN nodes 110 in the communication system 100 may be the same type of node or different types of nodes. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative. For example, the network element 120i in FIG. 1 may be a helicopter or an unmanned aerial vehicle and configured as a mobile base station. To the terminal 120j accessing the RAN 100 through the network element 120i, the network element 120i is a base station. However, to the base station 110a, the network device 120i is a terminal. Both the RAN node 110 and the terminal 120 are sometimes referred to as communication devices. For example, the network elements 110a and 110b in FIG. 1 may be understood as communication devices with base station functionality, and the network elements 120a-120j may be understood as communication devices with terminal functionality.

[0058] In possible scenarios, the RAN node 110 may be a base station, an evolved base station, a TRP, a next-generation base station, a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, etc. The RAN node 110 may be a macro base station (e.g., 110a), a micro base station or an indoor station (e.g., 110b), a relay node or a donor node, or a radio controller in a CRAN scenario. Optionally, the RAN node 110 may alternatively be a server, a wearable device, a vehicle, an in-vehicle device, etc. For example, the access network device in V2X technology may be a roadside unit (RSU).

[0059] In another possible scenario, multiple RAN nodes 110 cooperate to help terminals implement radio access, with different RAN nodes 110 individually implementing some of the functions of a base station. For example, a RAN node 110 may be a CU, DU, CU-CP, CU-UP, or radio unit (RU). The CU and DU may be located separately or may be included in the same network element, e.g., a BBU. The RU may be included in a radio frequency device or radio frequency unit, e.g., an RRU, AAU, or remote radio head (RRH).

[0060] In different systems, the CU (or CU-CP and CU-UP), DU, or RU may alternatively have different names, but those skilled in the art will understand the meaning of the names. For example, in an ORAN system, the CU-UP may also be referred to as an O-CU (open CU), the DU may also be referred to as an O-DU, the CU-CP may also be referred to as an O-CU-CP, the CU-UP may also be referred to as an O-CU-UP, and the RU may also be referred to as an O-RU. For ease of explanation, the CU, CU-CP, CU-UP, DU, and RU are used as illustrative examples in this application. Any one of the CU (or CU-CP and CU-UP), DU, and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0061] 2 is a diagram of an application scenario 200 according to an embodiment of the present application. As shown in FIG. 2, the application scenario 200 includes a UE 210, an RU 220, and a DU 230. The DU 230 includes at least one distribution module and at least one processing module. An example in which the DU 230 includes three processing modules and one distribution module is used for description.

[0062] Specifically, the UE 210 transmits air interface data to the RU 220, which transmits the air interface data to the distribution module 234. The distribution module 234 performs channel parsing and service identification on the air interface data to obtain service data 1 to service data 3 from the air interface data. Furthermore, the distribution module 234 transmits service data 1 to the processing module 231, which processes the service data 1. The distribution module 234 transmits service data 2 to the processing module 232, which processes the service data 2. The distribution module 234 transmits service data 3 to the processing module 233, which processes the service data 3.

[0063] Furthermore, in this embodiment of the present application, an antenna may exist between the UE 210 and the RU 220. For example, when the UE 210 transmits data to the RU 220, it can be understood that the source of the information is the UE 210 and the destination is the RU 220. The information may undergo necessary processing, such as format conversion, between the source and destination of the information. However, the destination can understand the valid information from the source. Similar descriptions in the present application can be understood in the same way, and the details will not be described again here.

[0064] For uplink data transmission, the RU 220 mainly performs processes such as analog-to-digital conversion, time-frequency domain conversion, or beam domain conversion on the air interface data received by the antenna, and the DU 230 completes resource demapping, channel estimation, channel demodulation, physical channel-related processing, etc. on the air interface data reported by the RU 220. Therefore, the RU 220 mainly performs the function of receiving and forwarding air interface data, and the DU 230 is mainly responsible for the function of performing data processing on the air interface data uploaded by the RU 220.

[0065] As can be seen from Figure 2, air interface data is transmitted through the following path: UE 210 → RU 220 → distribution module 234 → (processing modules 231-233). In the above transmission procedure, the overall processing latency of air interface data is high, which greatly affects the low latency requirements of low latency services. Therefore, the overall latency of data processing needs to be reduced urgently.

[0066] In consideration of the above technical problems, the present application provides a data processing method and a communication device, so as to reduce the overall latency of data processing.

[0067] The data processing method and communication device of the present application will be described below with reference to the accompanying drawings.

[0068] 3 is a schematic interaction flowchart of a data processing method 300 according to an embodiment of the present application. The method procedures in FIG. 3 may be performed by the radio frequency unit and the distributed unit of the network device, or may be performed by modules and / or components (e.g., chips or integrated circuits) that can be implemented in or connected to the radio frequency unit and the distributed unit and have corresponding functions. This is not limited here. The following uses the radio frequency unit and the distributed unit as an example for explanation. As shown in FIG. 3, the method 300 includes the following steps:

[0069] S310: The radio frequency unit determines a resource feature 1 of the first service data.

[0070] Specifically, the radio frequency unit in S310 may be an RU or a module having a radio frequency function, such as an RRU or an AAU. Therefore, the radio frequency unit is a higher concept of the RU or the RRU. Furthermore, the distributed unit may be a DU or another unit or module capable of performing similar or the same function. This is not a limitation of the present application. Therefore, the distributed unit is a higher concept of the DU.

[0071] In this embodiment of the present application, the radio frequency unit has the function of performing parsing and transformation in the time domain, frequency domain, spatial domain, etc. Therefore, the radio frequency unit can perform channel parsing and air interface data segmentation on the air interface data transmitted by the terminal device to obtain each service data in the air interface data. It can be understood that the resource feature corresponding to each service data in the air interface data is different. For example, the resource feature of the first service data in the air interface data is resource feature 1, the resource feature of the second service data in the air interface data is resource feature 2, and so on, and the resource feature of the Nth service data in the air interface data is resource feature N.

[0072] Furthermore, the air interface data division may be as follows: the radio frequency unit divides the air interface data into multiple parts (one part is one service data) according to different resource characteristics of the service data.

[0073] In a possible implementation, the resource characteristics include, but are not limited to, one or more of the following: latency information, frequency domain information, or spatial domain information. For example, the first service data is large uplink data, and the resource characteristics of the first service data are 20 MHz to 100 MHz in the frequency domain; the first service data is positioning data, and the resource characteristics of the first service data are Symbol 11 and Symbol 12 / transmission time interval (TTI) in the time domain; or the first service data is ultra reliable and low latency communication (URLLC) data, and the resource characteristics of the first service data are 0 MHz to 20 MHz in the frequency domain. As a result, the radio frequency unit divides the air interface data according to the resource characteristics of the service data, and obtains the resource characteristics and each service data of each service data.

[0074] Optionally, the resource characteristics listed above may further include a combination of multiple parameters, such as latency and frequency domain, which is not limited here.

[0075] Optionally, the resource characteristics may further include code domain information, for example, but not limited to, information such as spreading code, spreading code, scrambling code, etc.

[0076] S320: The radio frequency unit sends first service data to the processing module 1 based on the resource characteristic 1.

[0077] Specifically, the radio frequency unit obtains and determines the resource characteristics of each service data, and then sends the corresponding service data to a processing module in the distributed unit. For example, the radio frequency unit sends first service data to processing module 1 in the distributed unit based on resource characteristic 1. The processing module 1 in the distributed unit can process the first service data.

[0078] The processing module 1 may be understood to be any one of at least one processing module included in the distribution unit.

[0079] Compared with the method in which the radio frequency unit transmits service data to the distributed unit, which then performs resource feature identification on the service data and forwards the service data to the corresponding processing module, the method in which the radio frequency unit performs resource feature identification on the service data and then transmits the corresponding service data to the processing module in the distributed unit can reduce the overall latency of data processing.

[0080] Furthermore, the radio frequency unit can transmit the corresponding service data to the processing module in the distribution unit, and the distribution unit no longer needs a module or integrated circuit configured to perform the service data distribution function. In this way, the overall cost of the network device can be reduced.

[0081] Based on the above technical solutions, the present application can further help reduce the complexity of data interaction between the radio frequency unit and the distribution unit of a network device.

[0082] As a result, in the present application, the radio frequency unit can obtain and determine the resource characteristics of the service data, determine a corresponding processing module in the distributed unit according to the resource characteristics of the service data, and send the service data to the corresponding processing module. In this way, the transmission latency of the air interface data from the terminal device to the processing module in the distributed unit can be reduced, thereby reducing the overall latency of data processing.

[0083] Optionally, in a possible implementation, the method 300 may further include the following steps:

[0084] 310a: The radio frequency unit receives indication information 1 from a main processing module in the distributed unit, the indication information 1 indicating at least one mapping relationship, each mapping relationship associating one resource feature with one processing module.

[0085] S310b: The radio frequency unit determines a processing module 1 based on the mapping relationship 1 and the resource characteristic 1.

[0086] Specifically, the radio frequency unit transmits the first service data to the processing module 1 based on the resource characteristics 1 according to the mapping relationship indicated in the instruction information 1 transmitted to the radio frequency unit by the main processing module in the distributed unit. Specifically, the main processing module in the distributed unit indicates to the radio frequency unit the association relationship between the resource characteristics of each service data and the processing module. The radio frequency unit can determine the corresponding processing module based on the determined resource characteristics of the service data together with the mapping relationship. Furthermore, the radio frequency unit transmits the corresponding service data to the processing module.

[0087] In this way, the radio frequency unit can obtain the mapping relationship between the processing modules of the distributed units and the resource characteristics of the service data by interacting with the distributed units, and the radio frequency unit determines the resource characteristics of the service data, and then determines the processing modules associated with each service data based on the above mapping relationship.

[0088] At least one mapping relationship in S310a includes mapping relationship 1, which associates resource feature 1 with processing module 1. Optionally, mapping relationship 1 associating resource feature 1 with processing module 1 may be as follows: mapping relationship 1 associates an identifier of resource feature 1 with an identifier of processing module 1. In the present application, an identifier may be set for the resource feature of each service data. For example, 20 MHz to 100 MHz in the frequency domain corresponds to identifier 1 (the identifier of the resource feature), 0 MHz to 10 MHz in the frequency domain corresponds to identifier 2 (the identifier of the resource feature), and so on. This is not limited here.

[0089] In a possible implementation, one resource feature may be associated with one or more processing modules, for example, processing module 1 and processing module 2 may be configured to process first service data.

[0090] Optionally, one processing module may be associated with one or more resource features. For example, processing module 1 may be further configured to process second service data.

[0091] It can be understood that S310a and S310b occur before S320.

[0092] In a possible implementation, the indication information 1 in S310a may include identifiers of multiple processing modules and multiple resource features. Specifically, examples of the indication information 1 are: {processing module identifier 1, resource feature 1}, {processing module identifier 2, resource feature 2}, ..., {processing module identifier N, resource feature N}, etc. The processing module identifier 1 corresponds to the processing module 1, the processing module identifier 2 corresponds to the processing module 2, ..., the processing module identifier N corresponds to the processing module N. Specifically, the distributed unit may send the identifiers of the processing modules in the distributed unit and the resource features associated with each processing module to the radio frequency unit, so that the radio frequency unit can determine the corresponding processing module based on the resource features of the service data.

[0093] Optionally, in a possible implementation, the identifier of the processing module can be indicated by using the destination address of the processing module. Correspondingly, the indication information 1 includes the destination addresses of multiple processing modules and the resource characteristics associated with the processing module corresponding to each destination address. Given the destination addresses of the processing modules, the radio frequency unit can determine the processing module corresponding to each service data.

[0094] Optionally, in a possible implementation, the method 300 may further include the following steps:

[0095] S310c: The radio frequency unit receives indication information 2 from the main processing module of the distributed unit, where the indication information 2 indicates the status of at least one processing module.

[0096] Specifically, the instruction information 2 indicates the status of at least one processing module, and the status of the processing module includes an operating state and a non-operating state. The operating state indicates that the processing module is capable of processing service data, and the non-operating state indicates that the processing module is unable to process service data. Furthermore, the radio frequency unit determines whether to transmit the first service data to the processing module 1 based on the instruction of the instruction information 2. In this way, the radio frequency unit can transmit the first service data to the processing module 1 only if the radio frequency unit determines that the processing module 1 is in an operating state based on the instruction information 2. This can improve the efficiency of data interaction between the radio frequency unit and the processing module in the distributed unit.

[0097] For example, when the instruction information 2 indicates that the processing module 1 is in an operating state, the radio frequency unit transmits the first service data to the processing module 1. For another example, when the instruction information 2 indicates that the processing module 1 is in an inoperating state, the radio frequency unit does not transmit the first service data to the processing module 1.

[0098] Optionally, the instruction information 2 may be a part of the instruction information 1, or the instruction information 2 may exist independently from the instruction information 1. This is not a limitation of the present application.

[0099] S310c is performed before S320, and the order in which S310c and S310a and S310b are performed is not limited.

[0100] The method 300 is further described below with reference to the other accompanying drawings.

[0101] 4 is a schematic interaction flowchart of a data processing method 400 according to an embodiment of the present application. The method procedures of FIG. 4 may be performed by the radio frequency unit and the distributed unit, or may be performed by modules and / or components (e.g., chips or integrated circuits) that can be implemented in or connected to the radio frequency unit and the distributed unit and have corresponding functions. This is not limited in the present application. The following uses the radio frequency unit and the distributed unit as an example for explanation. As shown in FIG. 4, the method 400 includes the following steps:

[0102] Optionally, S410: the radio frequency unit receives instruction information 1 from the main processing module of the distributed unit, where the instruction information 1 indicates mapping relationship 1 to mapping relationship 3, where mapping relationship 1 associates resource feature 1 with processing module 1, mapping relationship 2 associates resource feature 2 with processing module 2, and mapping relationship 3 associates resource feature 3 with processing module 3.

[0103] For a description of S410, please refer to the above description of S310a, and the details will not be repeated here.

[0104] S420: The radio frequency unit divides the air interface data to determine a resource feature 1 of the service data 1, a resource feature 2 of the service data 2, and a resource feature 3 of the service data 3.

[0105] For a description of the division of air interface data by radio frequency units, please refer to the above description, and the details will not be described again here.

[0106] S430: The radio frequency unit sends service data 1 to processing module 1 based on mapping relationship 1 and resource feature 1, sends service data 2 to processing module 2 based on mapping relationship 2 and resource feature 2, and sends service data 3 to processing module 3 based on mapping relationship 3 and resource feature 3.

[0107] Accordingly, processing module 1 receives service data 1 from the radio frequency unit, processing module 2 receives service data 2 from the radio frequency unit, and processing module 3 receives service data 3 from the radio frequency unit. Furthermore, processing module 1 processes service data 1, processing module 2 processes service data 2, and processing module 3 processes service data 3.

[0108] As a result, the radio frequency unit can send corresponding service data to each processing module based on the association relationship between the resource characteristics of the service data and the processing module, and then the processing module processes the service data. In this way, the overall latency of data processing can be reduced.

[0109] It can further be appreciated that the distributed units do not require the distribution module shown in Figure 2 because the radio frequency units can perform functions such as channel parsing and service identification, and therefore the overall cost overhead and complexity of the network devices can be reduced.
