Control Information Processing in Mobile Communication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, particularly in LTE, there is a need for efficient processing of control information within data units, as existing techniques like HARQ and ARQ do not adequately address the reordering and processing of control information, leading to potential delays and malfunctions in communication quality.
Innovation Solution
A method and apparatus that differentiate between two types of control information, processing Type 1 immediately and Type 2 after reordering, using a control information demultiplexer and reception buffer to ensure timely and correct processing, including generating status reports based on poll commands with time indications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If control information is processed immediately without reordering, then processing speed is improved, but processing accuracy deteriorates
Solution Approach 1:
The patent segments control information into two distinct types: Type 1 control information that requires immediate processing irrespective of data unit reordering, and Type 2 control information that requires processing only after reordering is complete. This segmentation allows the system to handle different control information with appropriate timing strategies, resolving the contradiction between speed and accuracy by applying different processing rules to different segments of control information.
2Manufacturing precision
If control information processing is delayed for reordering, then processing accuracy is improved, but processing speed deteriorates
Solution Approach 1:
By dividing control information into Type 1 and Type 2 categories, the patent enables selective processing timing. Type 1 control information (such as poll commands triggering status reports) is processed immediately to maintain speed, while Type 2 control information is processed after reordering to ensure accuracy. This segmentation resolves the speed-accuracy tradeoff by optimizing processing timing for each control information type according to its specific requirements.

AI summary
A method and apparatus for processing control information included in a data unit in a mobile communication system are provided. A receiver processes control information of a first type immediately irrespective of reordering of a received data unit, when the received data unit comprises the control information of the first type. The receiver processes control information of a second type after reordering of the received data unit, when the received data unit comprises the control information of the second type.
