Solution Overview
Problem
Existing radio communications systems typically support only a single air interface, failing to accommodate multiple air interfaces, which limits their ability to meet diverse service requirements in 5G networks.
Innovation Solution
A Media Access Control method is introduced, where a radio access device is equipped with dedicated control entities for each air interface and a common control entity, enabling interaction between them to implement Media Access Control functions, such as resource scheduling, multiplexing, and hybrid automatic repeat request, thereby supporting multiple air interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a radio access device supports only a single air interface, then the device complexity is low, but the adaptability to diverse service requirements deteriorates
Solution Approach 1:
The MAC function is segmented into a common control entity and multiple dedicated control entities, where each dedicated control entity corresponds to a specific air interface type. This segmentation allows the radio access device to support multiple air interfaces while maintaining manageable complexity through functional separation.
Solution Approach 2:
The common control entity provides universal MAC functions that are shared across all air interface types, while dedicated control entities handle air-interface-specific operations. This multi-functionality architecture enables the device to adapt to diverse service requirements through different air interfaces without proportionally increasing overall complexity.
2Adaptability or versatility
If a radio access device supports multiple air interfaces, then the adaptability to diverse service requirements is improved, but the device complexity increases
Solution Approach 1:
The MAC function is divided into common and dedicated control entities, with each dedicated control entity handling a specific air interface type. This segmentation enables multi-air interface support while controlling complexity through functional specialization and modular architecture.
Solution Approach 2:
The common control entity merges shared MAC functions that serve all air interfaces, while dedicated control entities handle interface-specific operations. This combining approach reduces overall complexity by identifying and consolidating common functionalities that can be reused across multiple air interfaces.

AI summary
This application discloses a Media Access Control method, and pertains to the field of wireless communications technologies. The method is applied to a radio access device that supports at least two types of air interfaces, and the radio access device includes dedicated control entities respectively corresponding to the at least two types of air interfaces and a common control entity. The common control entity determines a dedicated control entity corresponding to a specified air interface between the radio access device and a terminal, and interacts with the dedicated control entity corresponding to the specified air interface, to implement a Media Access Control function of the specified air interface. Execution entities of a Media Access Control MAC layer of the radio access device are divided into one common control entity and a dedicated control entity that corresponds to each of at least one type of air interface, and the common control entity interacts with the dedicated control entity corresponding to any air interface, to implement a Media Access Control function of the air interface, so that the radio access device in a radio communications system supports a plurality of air interfaces.
