Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a baseband carrier resource allocation method, apparatus, baseband processing unit, and system. Background Technology

[0002] In a distributed base station, a macro base station comprises a baseband section and a radio frequency (RF) section, namely a baseband processing unit and an RF processing unit. The baseband processing unit is responsible for baseband signal processing and transmission. The RF processing unit is responsible for RF transceiver. The baseband processing unit and the RF processing unit are connected via optical fiber. During network deployment, the baseband processing unit, along with the core network and wireless network control equipment, is centrally located in a data center and connected to the RF processing units deployed at planned sites via optical fiber to achieve network coverage. In this mode, one baseband processing unit can support the connection of multiple RF processing units, and the RF processing units can be extended remotely via optical fiber. The baseband processing unit and multiple RF processing units can be flexibly networked in star or chain topologies, bringing great convenience.

[0003] In traditional network implementations, the baseband cell carrier resources of a baseband processing unit are associated with its optical port. Once the radio frequency (RF) processing unit establishes a connection with the baseband processing unit through the optical port, the cell carrier resources allocated to all RF processing units under that optical port become fixed. This results in all RF processing units connected under the same optical port only being able to cover a fixed number of cells.

Optionally, the central processing unit can be implemented using a CPU, and the baseband carrier resource configuration device can be implemented using an FPGA.

[0061] The terms "module," "unit," and "subunit" used above refer to combinations of software and / or hardware that perform a predetermined function. Although the apparatus described in some embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated. It should be noted that the modules described above can be functional modules or program modules, and can be implemented in either software or hardware. For modules implemented in hardware, the modules can reside in the same processor; or the modules can be located in different processors in any combination.

[0062] In one embodiment, a baseband carrier resource configuration method is provided, which can be run in... Figure 1 Computer equipment can also run on Figures 3 to 5 Any baseband carrier resource configuration device in the middle, Figure 6 This is a flowchart of the baseband carrier resource configuration method in this embodiment, which includes the following steps:

[0063] Step S601: The allocation module obtains optical port distribution data, which includes cell information and bandwidth information.

[0064] The distribution module obtains optical port distribution data through the central processing unit, which can receive manually configured parameters and generate optical port distribution data.

[0065] In step S602, the allocation module determines the target resource in the first storage module or the second storage module according to the optical port distribution data, and extracts the antenna carrier data from the target resource.

[0066] In the downlink direction: the allocation module determines the target resource and the number of antenna carrier data to be extracted in the first storage module based on the cell information; the allocation module determines the size of each antenna carrier data to be extracted based on the bandwidth information; the allocation module extracts antenna carrier data from the target resource according to the determined number and size.

[0067] In the uplink direction: the allocation module determines the target resource and the number of antenna carrier data to be extracted in the second storage module based on the cell information; the allocation module determines the size of each antenna carrier data to be extracted based on the bandwidth information; the allocation module extracts antenna carrier data from the target resource according to the determined number and size.

[0068] In step S603, the allocation module sends the antenna carrier data to the first interface or the second interface.

[0069] In the downlink direction: the allocation module distributes data according to the optical port, determines the baseband resources in the first storage module, and extracts antenna carrier data from the baseband resources. The antenna carrier data includes user plane data generated by the central processing unit. The allocation module sends the antenna carrier data to the second interface.

[0070] In the uplink direction: the allocation module distributes data according to the optical port, determines the carrier frequency resources in the second storage module, and extracts antenna carrier data from the carrier frequency resources. The antenna carrier data includes user plane data generated by the radio frequency processing unit. The allocation module sends the antenna carrier data to the first interface.

[0071] Compared to related technologies, this embodiment adds a baseband carrier resource configuration device to the baseband processing unit to establish a baseband resource carrier pool within the baseband processing unit. This breaks the one-to-one fixed connection between cell baseband carrier resources and optical ports, allowing for flexible configuration of the correspondence between cell baseband carrier resources and optical ports. This configuration allows for the allocation of cell baseband carrier resources supported by the optical port according to actual needs, thus enabling flexible configuration of cell information supported by any radio frequency processing unit in the network mode. Furthermore, the coverage areas of multiple radio frequency processing units can be freely combined to meet different coverage requirements. Through these steps, the problem of inflexible configuration of baseband carrier resources in related technologies is solved, achieving flexible configuration of baseband carrier resources.

[0072] In one embodiment, the allocation module sends antenna carrier data to the first interface, which can be achieved in the following way:

[0073] The allocation module merges antenna carrier data from different optical ports that have the same position sequence and sends the merged antenna carrier data to the first interface. This configuration allows carrier resources from the same cell to be distributed to radio frequency processing units connected to different optical ports, thereby expanding the coverage area. During uplink processing, uplink data from radio frequency processing units under different optical ports belonging to the same cell need to be merged.

[0074] In one embodiment, the first storage module stores baseband resources, with each cell's baseband resources stored in units of one sampling point, and these sampling points are stored consecutively. This configuration adapts to processing downlink data streams with different bandwidths. The storage depth of the first storage module is determined based on the line rate of the first interface and the configuration parameters of the current cell's baseband resources. This configuration allows the storage depth of the first storage module to be adaptively adjusted, improving the flexibility of signal processing and multi-bandwidth adaptability. Storage depth refers to the number of sampling points that can be stored per unit of storage space; one method for calculating storage depth is: Storage Depth = Sampling Rate × Sampling Time.

[0075] In one embodiment, the second storage module stores carrier frequency resources, with each optical port carrier frequency resource stored in units of one sampling point, and these sampling points are stored consecutively. This configuration allows for the adaptation to uplink data streams of different bandwidths. The storage depth of the second storage module is determined based on the line rate of the second interface and the configuration parameters of the current cell's baseband resources. This configuration enables the storage depth of the second storage module to be adaptively adjusted, improving the flexibility of signal processing and multi-bandwidth adaptability.

[0076] In one embodiment, the first storage module stores baseband resources, with each cell's baseband resources stored in units of one sampling point, and these sampling points are stored consecutively. The storage depth of the first storage module is determined based on the line rate of the first interface and the configuration parameters of the current cell's baseband resources. The second storage module stores carrier frequency resources, with each optical port carrier frequency resource stored in units of one sampling point, and these sampling points are stored consecutively. The storage depth of the second storage module is determined based on the line rate of the second interface and the configuration parameters of the current cell's baseband resources. This configuration adapts to processing downlink and uplink data streams of different bandwidths, and allows the storage depths of the first and second storage modules to be adaptively adjusted, improving the flexibility of signal processing and multi-bandwidth adaptability.

[0077] In one embodiment, another baseband carrier resource allocation system is provided. Figure 7 This is a schematic diagram of the baseband carrier resource allocation system in this embodiment, as shown below. Figure 7 As shown, the baseband carrier resource allocation system includes:

[0078] The system comprises a baseband processing unit and a radio frequency (RF) processing unit, which are connected to each other. The baseband processing unit includes a central processing unit (CPU), a baseband carrier resource configuration device, and an optical port. The baseband carrier resource configuration device includes a first storage module, a second storage module, an allocation module, a first interface, and a second interface. The allocation module is connected to both the first and second storage modules. The first interface connects the first storage module to the CPU, and the CPU stores baseband resources. The second interface connects the second storage module to the optical port. The allocation module executes a baseband carrier resource configuration method. The CPU includes a third storage module and a human-machine interface (HMI) module. The third storage module stores baseband resources, and the HMI module is connected to the first, second, and allocation modules. The HMI module receives configuration parameters and sends them to the first, second, or allocation modules. The CPU is implemented using a CPU, and the baseband carrier resource configuration device is implemented using an FPGA, enabling concurrent real-time processing of multiple data streams and offering greater flexibility in functionality.

[0079] Baseband resources, also known as user plane data, are the wireless data exchanged between the RRU and BBU. Baseband resources are processed by the BBU's CPU and transmitted between the CPU and FPGA via a standard CPRI interface. Abundant baseband resources interact with the FPGA through multiple CPRI interfaces.

[0080] The allocation module and human-machine interface module enable flexible reconfiguration and allocation of all baseband resources transmitted from the BBU. The human-machine interface data module primarily uses a CPU+FPGA approach, with data exchange between the CPU and FPGA via a local bus interface. The CPU acquires and stores configuration parameters; different configuration parameters are stored at different addresses, and the acquired parameters are transmitted via the local bus interface. When the FPGA acquires the required configuration parameters, it reads the data based on the corresponding address stored in the local bus interface. These configuration parameters can also be manually input.

[0081] The internal structure of an FPGA is described below.

[0082] The first storage module is used to store user plane data sent from the BBU to the RRU. Figure 8 This is a schematic diagram of the baseband resource pool in this embodiment, as shown below. Figure 8As shown, in the downlink direction, each cell baseband resource entering the first storage module has its own independent storage space. This independently allocated storage space can avoid interference and influence between multiple cell baseband resources. Each cell baseband resource is stored in units of one sampling point, and each sampling point is stored contiguously. The storage depth can be automatically adjusted and changed according to the CPRI line rate configured in the current system and the configuration parameters of the current cell baseband resources.

[0083] The allocation module is used to integrate all interactive data between uplink and downlink, and to distribute and match uplink and downlink data based on the configuration parameters obtained from the human-computer interaction module.

[0084] In the downlink direction, the allocation module uses each BBU optical port as a processing unit. It obtains cell information and bandwidth information for the current optical port data distribution through the human-machine interface module. Based on this information, it extracts the necessary data from the corresponding cell resource storage block in the first storage module. The unit of data extraction is one AXC carrier data point. The number of AXC carriers is determined by the RRU's transmit / receive capabilities. The size of each AXC carrier data point is automatically calculated based on the current bandwidth information. Multiple acquired AXC carrier data points are automatically matched and combined according to the base frame format in the CPRI protocol.

[0085] In the uplink direction, the allocation module processes each BBU cell as a unit. All uplink data from the RRU is stored in the second storage module. The module obtains cell information and bandwidth information for all optical port distributed data through the human-machine interface module, extracting all RRU carrier frequency resources matching the current cell information. The unit for carrier frequency data extraction is one AXC carrier data point. The position of each AXC carrier data point is determined by the configuration parameters of the human-machine interface module. AXC carrier data points from different optical ports with the same position sequence need to be merged. The number of AXC carriers in each cell is determined by the cell's own parameter attributes. The size of each AXC carrier is automatically calculated based on the current cell's bandwidth information. Multiple acquired AXC carrier data points are automatically matched and combined according to the base frame format in the CPRI protocol.

[0086] The number of AXC carriers has a fixed relationship with cell parameter attributes (2T2R or 4T4R, transmit / receive capability). Once the cell's transmit / receive capability is determined, the number of AXC carriers in the current cell can be determined using a lookup table. For example, bandwidth information and AXC carrier data size have a fixed correspondence; after obtaining the current cell's bandwidth information, the AXC carrier data size information can be automatically matched using a lookup table. Carrier resources from the same cell are allocated to radio frequency processing units connected to different optical ports to expand the coverage area. During uplink processing, uplink data from the same cell originating from radio frequency processing units under different optical ports needs to be merged.

[0087] The second storage module stores user plane data uploaded by the RRU to the BBU. Each optical port corresponds to one CPRI interface. The carrier frequency data received through the CPRI interface represents the data received from all RRUs under that optical port. The carrier frequency storage module stores data from all optical ports supported by the BBU. Each carrier frequency data entering the second storage module also has its own independent storage space, and the data storage of carrier frequency data from different optical ports does not interfere with or affect each other. Each carrier frequency data is stored in units of one sampling point, and the sampling points are stored contiguously. The storage depth can be automatically adjusted and changed according to the current system configuration of the CPRI line rate and the current cell baseband resource configuration parameters to improve the flexibility of signal processing and multi-bandwidth adaptability.
