Base Station Service Scheduling Decoupling RLC MAC Entities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current base stations face challenges in meeting the high bandwidth requirements for data transmission between boards, particularly in multicarrier scenarios, which affects network performance and efficiency.
Innovation Solution
A service scheduling method where the MAC entity reports bearer information to the RLC entity, allocates service data and control information, and performs packet assembly, allowing for decoupling between service data transmission and scheduling, thereby reducing the bandwidth needed between boards.

Engineering Contradiction Analysis
1Productivity
If service data is transmitted in real-time between boards in a multicarrier scenario, then network performance is improved, but bandwidth requirements between boards become excessively high
Solution Approach 1:
The patent applies preliminary action by having the RLC entity allocate and send service data to the data buffer in advance, before the MAC entity needs to schedule user equipment. This advance allocation allows the MAC entity to directly read from the buffer without requiring high-speed real-time data transmission between boards during scheduling operations, thereby reducing the bandwidth requirements while maintaining network performance
2Productivity
If RLC entity and carrier are deployed on the same board, then data transmission efficiency is improved, but device complexity increases when supporting multiple carriers
Solution Approach 1:
The patent applies segmentation by separating the RLC entity from the MAC entity and carrier deployments. The RLC entity can be centrally located while carriers are distributed across different boards, with service data being sent to a shared data buffer. This segmentation allows efficient data transmission without requiring every carrier to be co-located with the RLC entity, thereby reducing device complexity in multicarrier scenarios while maintaining transmission efficiency

AI summary
Embodiments of the present invention disclose a service scheduling method and a base station. The method includes: reporting, by a Medium Access Control MAC entity of a carrier, bearer information of the carrier to a Radio Link Control RLC entity; allocating, by the RLC entity, service data and control information to the carrier, and sending the service data and the control information to a data buffer of the carrier; determining, by the MAC entity, a user equipment that needs to be scheduled, and acquiring the service data and the control information from the data buffer; and performing, by the MAC entity, RLC packet assembly and MAC packet assembly on the service data, and sending the service data experiencing the packet assembly to the user equipment. This implements decoupling between service data transmission from the RLC entity to the MAC entity and service scheduling by the MAC entity and prevents that a rather high bandwidth is required between boards.
