MAC Entity Control Information Integration for Radio Traffic Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems face increased traffic burden due to the need to transmit the same control information to multiple entities across different sub-layers, leading to inefficient data transmission and increased traffic volume.
Innovation Solution
A radio transmission apparatus and method that integrates control information at the MAC entity, allowing it to be transmitted efficiently to multiple entities without duplicating it across multiple RLC and PDCP entities, thereby reducing traffic volume by adding the same control information only once at the MAC entity before transmission to the physical layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control information is added at each RLC entity to be transmitted to multiple opposing entities, then control information can be delivered to all RLC entities on the opposing side, but the traffic volume of radio communication increases
Solution Approach 1:
The patent merges the control information from multiple RLC entities into a single integrated control information element at the MAC entity. Instead of transmitting separate control information from each RLC entity, the MAC entity consolidates them into one unified control information that is then transmitted once to the opposing MAC entity, which distributes it to the appropriate RLC entities. This combining approach maintains reliable control information delivery while eliminating the traffic volume increase that would result from transmitting duplicate control information from each entity separately.
2Ease of operation
If control information is transmitted by each entity separately, then each entity can process its own control information, but the data size grows by the amount of control information for each entity
Solution Approach 1:
The patent introduces the MAC entity as an intermediary that handles the consolidation and distribution of control information. The MAC entity receives control information from multiple RLC entities, integrates them into a single control information element, transmits it to the opposing MAC entity, and then distributes it to the appropriate RLC entities. This intermediary approach allows each RLC entity to maintain its autonomy in generating control information while avoiding the data size growth that would occur if each entity transmitted its control information separately, as the MAC entity's consolidation eliminates redundant transmissions.
3Quantity of substance
If control information is integrated at the MAC entity and transmitted once, then traffic volume is reduced, but the MAC entity must manage distribution to multiple entities
Solution Approach 1:
The patent applies multi-functionality to the MAC entity, which now performs multiple functions: it consolidates control information from multiple RLC entities, transmits the integrated control information to the opposing MAC entity, and distributes it to the appropriate RLC entities. By giving the MAC entity these multiple functions, the system reduces traffic volume through single transmission while managing the distribution complexity within a single entity rather than requiring separate transmission mechanisms from each RLC entity. The MAC entity's universal role in handling control information flow justifies the increased complexity by achieving significant traffic reduction.

AI summary
Instead of adding control information that should be passed on to two or more RLC entities or two or more PDCP entities on the counterpart side to data respectively in two or more RLC entities or two or more PDCP entities at the sending end, control information is added in MAC entity and then distributed to two or more RLC entities in MAC entity on the counterpart side.
