【技术领域】[Technical Field]

【背景技术】【Background technique】

In Long Term Evolution (LTE) systems, the baseband board is responsible for implementing physical layer protocols, baseband related algorithms, and product related features throughout the base station system. As the protocol evolves, the complexity of the physical layer protocol, the complexity of the algorithm, and the application scenarios of the product become more and more complex, requiring the processing capability of the baseband board to be higher and higher.

In the prior art, due to the gradual upgrading of technology and cost considerations, some base station systems have both an old version of the baseband board and a new version of the baseband board. The old version of the baseband board can support some old protocols, algorithms, and features; the new version of the new baseband board supports new protocols, algorithms, and features. The combination of the new and old versions of the baseband board is to use the old and new versions of the baseband board. Specifically, the old version of the baseband board handles some users, while the new version of the baseband board handles other users. Operators save a lot of money.

Correspondingly, the downlink resource pool of the base station system has two baseband boards: a main board and a slave board, the main board is a new version of the baseband board, and the slave board is an old version of the baseband board. The main board handles the channel of a part of the user, and the slave board processes the channel of another part of the user. The extent to which the slave board processes the user data to the bit level is ended, and then the bit level data is transmitted to the motherboard, and the remaining processing of all users is performed by the motherboard. Similarly, the uplink resource pool of the base station system has two baseband boards: a main board and a slave board, the main board processes a part of the user's channel, and the slave board processes another part of the user's channel.

The inventor of the present application found in long-term research and development, For the downlink resource pool, the bit level only accounts for 30% of the total computational load. The slave board does not share the processing amount of the entire downlink user well. For the uplink resource pool, the user allocates the board and the slave board according to the user. When multiple user frequency domain resources are multiplexed, if they are allocated on different baseband boards, it will cause repeated calculations and waste hardware resources.

【具体实施方式】【detailed description】

Currently, for the downlink of the LTE protocol, as more and more multi-antenna technologies are applied, the physical downlink shared channel (PDSCH, Physical Downlink Shared) Channels are becoming more and more complex, requiring more and more users to be able to simultaneously connect and transmit to the cell, which results in higher and higher requirements for the processing capability of the PDSCH channel to the baseband board.

For the LTE protocol uplink, the user equipment (UE, User Equipment) supports multi-antenna transmission, multi-cell cooperation, and more and more online transmission of users in the cell. The requirements for uplink demodulation for the processing capability of the baseband board are also increasing.

Referring to FIG. 1 , FIG. 1 is a schematic diagram of a method for implementing a downlink baseband resource pool in a LTE base station in a prior art. The downlink baseband resource pool has two baseband boards: a motherboard and a slave board, and the motherboard is a new version of the baseband board, and the slave board is an old version. Baseband board. The main control module of the base station manages the main board and the slave board at the same time, and the main control module allocates a part of the downlink users to the main board for processing, and allocates another part of the downlink users to the slave board for processing. The processing of the entire downlink user is divided into a bit level and a symbol level, and the data processing from the board to the downlink user to the bit level can be ended, and then the bit level data is transmitted to the main board, and the remaining processing of all the downlink users is completed by the main board.

In the above solution, the interaction between the master and the slave is the data of the downlink user to the bit level. In the data processing process of the entire downlink user, if the processing amount of the entire downlink user data is regarded as a whole, the processing operation of the bit level only accounts for 30% of the entire calculation amount, and 70% of the calculation amount is the symbol level. Processing, therefore, in the existing scheme, the slave board does not share the processing amount of the data of the entire downlink user well.

Referring to FIG. 2 and FIG. 3, FIG. 2 and FIG. 3 are implementation methods of an uplink baseband resource pool in an LTE base station in the prior art. The uplink baseband resource pool has two baseband boards: a main board and a slave board, and the main board is a new version of the baseband board. The board is an old version of the baseband board. The main control module repeatedly configures the information of the uplink user in the cell to the main board and the slave board; or configures the user information to the main board and the slave board according to load balancing; the main board L2 scheduling module sets the current transmission time interval according to load balancing (TTI). , Transmission Time Interval) The uplink user to be processed is allocated to the main board and the slave board for processing; the main uplink and the slave board are respectively allocated to the physical uplink shared channel of the uplink user (PUSCH, Physical) Uplink Shared Channel), physical uplink control channel (PUCCH, Physical Uplink Control) Channel) and the data carried by the SRS (Sounding Reference Signal) channel are processed.

There are three problems in the implementation of the foregoing uplink resource pool: First, when multiple user frequency domain resources are multiplexed, there are common processing parts among multiple users, and cooperation processing between multiple users also contributes to performance improvement. If the multiple users are assigned on different boards, it will cause double counting and waste hardware resources. Second, the PUSCH channel considers multiple points of cooperation (COMP, Coordinated) Multi-Point In the collaborative scenario, if the resource pool allocation is performed according to the user, and two users in the channel are allocated to different boards for processing, COMP data needs to be transmitted in multiple copies, and interference reduction is performed for the COMP cells (IC, Interference). Canceling) is also inconvenient to operate. Third, the L2 scheduling module of the main board can only be used for centralized scheduling. Each baseband board cannot be independently scheduled, and cannot be scheduled in parallel, which is easy to waste resources.

The invention will now be described in detail in conjunction with the drawings and embodiments.

Referring to FIG. 4, FIG. 4 is a flowchart of an implementation manner of a downlink baseband resource pool in an LTE base station according to the present invention, including:

Step S101: The main control module schedules channels of the corresponding downlink users to the main board and the slave board according to the information of the downlink users that have been configured on the main board and the slave board respectively.

The main control module is a module for controlling, scheduling, and configuring the main board and the slave board in the downlink baseband resource pool of the LTE base station, for example, configuring downlink user information to the main board and the slave board respectively, and scheduling the downlink user channel to the main board and the slave board respectively. For the main board and the slave board to process; to configure the cell information to the main board and the slave board respectively; according to the processing capability of the baseband board (main board or slave board), modify the parameters of the cell, and the like. When the baseband board is added to the LTE base station, the main control module automatically recognizes the newly added baseband board and the processing capability of the baseband board.

The main board and the slave board are the baseband boards of the LTE base station, and usually represent the new baseband board and the old baseband board. The number of the main board and the slave board is determined according to the actual application.

A downlink user refers to a user who sends information to a user equipment of a user. It should be noted that the downlink users herein may be downlink users of the same cell or downlink users of different cells.

A channel is a channel through which information is transmitted, that is, a path through which information is transmitted.

The channels of the downlink users include, but are not limited to, a physical downlink shared channel PDSCH, a physical downlink control channel PDCCH, a physical broadcast channel PBCH, and the like.

The main control module separately configures the information of the downlink user for the main board and the slave board according to the identified main board and the slave board. According to the information of the configured downlink users, the main control module schedules the channels of the corresponding downlink users to the main board and the slave board, so that the data carried by the main board and the slave board on the channel are processed.

Step S102: The main board and the slave board respectively perform bit level and symbol level processing on the information carried by the channel of the downlink user scheduled by the main control module, and obtain time domain data generated by the main board and time domain data generated by the slave board.

Bit-level processing mainly includes: transport block (Transport) Block, TB) CRC addition, sub-block division and CRC addition, channel coding, rate matching, code block concatenation, channel coding and rate matching of control information, service data and control information multiplexing, channel interleaving, and data bit scrambling Wait.

The symbol level processing mainly includes: scrambling the channel-coded bits in each codeword transmitted on the physical channel; modulating the scrambled bits to obtain a complex modulation symbol; and mapping the obtained complex modulation symbols At one or more transport layers; precoding the complex modulation symbols for each layer; mapping complex modulation symbols on each antenna port to resource elements (RE, Resource) Element); generates a complex time domain signal on each antenna port.

The time domain is the basic nature of the signal, and the interaction between the reactive signal and the interconnect is clearly understood. The main board performs bit level and symbol level processing on the information carried by the channel of the downlink user scheduled by the main control module, and obtains time domain data generated by the main board; information carried by the board to the channel of the downlink user scheduled by the main control module. Perform bit-level and symbol-level processing to obtain time domain data generated from the board.

In the downlink baseband resource pool, the LTE base station configures downlink user information for the main board and the slave board according to the downlink user, and performs processing on the bit-level and symbol level of the allocated downlink user channel by the main board and the slave board. Can properly utilize the processing power of the motherboard and slave board.

Referring to FIG. 5 to FIG. 7 , FIG. 5 to FIG. 7 are flowcharts of a third implementation manner of a method for implementing a downlink baseband resource pool in an LTE base station according to the present invention, including:

Step S201: The main control module separately configures information of the downlink user to the main board and the slave board.

The main control module separately configures downlink user information for the main board and the slave board according to the identified main board and the slave board.

The main control module is a module for controlling, scheduling, and configuring the main board and the slave board in the downlink baseband resource pool of the LTE base station.

Step S202: The main control module schedules channels of the corresponding downlink users to the main board and the slave board according to the information of the downlink users that have been configured on the main board and the slave board respectively.

According to the information of the configured downlink users, the main control module schedules the channels of the corresponding downlink users to the main board and the slave board, so that the data carried by the main board and the slave board on the channel are processed.

When the main control module dispatches the channel of the corresponding downlink user to the main board and the slave board, the channel of the corresponding downlink user may be separately scheduled to the main board and the slave board according to the two situations, respectively:

The first type of basis: according to the downlink user information and load balancing configured by the main board and the slave board respectively, the main control module schedules the downlink user channel to be processed by the current transmission time interval TTI corresponding to the load condition of the main board and the slave board.

Transmit Time Interval (TTI) is in Universal Mobile Telecommunications System (UMTS, Universal Mobile) A parameter in Telecommunications System and other digital telecommunication networks, such as LTE systems, refers to the length of an independent decoded transmission in a wireless link. TTI It is related to the size of the data block from the higher network layer to the wireless link layer. It is the basic unit of time governed by radio resource management (such as scheduling). Each transport channel corresponds to one service. Since the delay requirements of various services are different, the TTIs are different, and the TTI may be 10 ms, 20 ms, 40 ms, or 80 ms.

Load balancing means that the number of downlink users on the main board and the slave board is roughly equal. For example, the number of downlink users configured by the main control module to the mainboard load is 10, and the number of downlink users configured for the slave load is 5, at this time, according to the load. In the equalization, the main control module schedules the downlink user's channel to be processed by the current TTI corresponding to the slave load condition from the slave board.

The second basis: the main control module dispatches the downlink and the slave board and the slave board according to the downlink user information that has been configured on the board and the slave board, and the processing capability or supported characteristics of the board and the slave board. User's channel.

The processing capacity of the main board and the slave board, for example, the traffic of the main board is 500M, and the traffic of the slave board is 300M. At this time, the channel of the downlink user whose downlink requirement is less than 300M can be scheduled to be processed by the slave board. The downlink user's channel scheduling of the downlink user whose traffic requirement is greater than 300M is processed by the main board.

The features supported by the motherboard and the slave board, for example, the new features of the product are used by the downlink users. When the slave board cannot process, the downlink user's channel can be scheduled to the motherboard for processing.

In practical applications, you can consider the processing capabilities of the motherboard and slave boards and the features supported by the motherboard and slave boards, or only consider the processing capabilities of the motherboard and slave boards, or only the features supported by the motherboard and slave boards.

When the main control module schedules the channel of the corresponding downlink user to the main board and the slave board, the above two basis can be selected according to the actual application.

Step S203: The main board and the slave board respectively perform bit level and symbol level processing on the information carried by the channel of the downlink user scheduled by the main control module, and obtain time domain data generated by the main board and time domain data generated by the slave board.

The bit-level processing mainly includes: CRC addition of the transport block, sub-block splitting and CRC addition, channel coding, rate matching, code block cascading, channel coding and rate matching of control information, multiplexing of service data and control information, channel interleaving, and Data bit scrambling, etc.

The symbol level processing mainly includes: scrambling the channel-coded bits in each codeword transmitted on the physical channel; modulating the scrambled bits to obtain a complex modulation symbol; and mapping the obtained complex modulation symbols At one or more transport layers; precoding the complex modulation symbols for each layer; mapping complex modulation symbols on each antenna port to resource elements; generating a complex time domain signal on each antenna port.

Step S203 specifically includes:

Step S203a: The main board and the slave board respectively perform bit level and symbol level processing on information carried by the physical downlink shared channel PDSCH of the downlink user scheduled by the main control module.
