Solution Overview
Problem
High-frequency wireless communication systems, particularly those using millimeter waves, face challenges in efficiently transmitting control information due to the need for precise timing and physical properties, especially with the ubiquitous use of beamforming, which complicates the handling of control channels.
Innovation Solution
A method and system for transmitting control information in a control information container with a set of predefined container sizes, allowing simplified encoding and decoding, eliminating the need for a dedicated control channel, and enabling efficient use of resources by mapping containers to available time, frequency, or code resources, with error coding adapted based on priority and channel conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If control information is transmitted using traditional dedicated control channels in high-frequency wireless communication systems, then transmission reliability is maintained through established protocols, but device complexity and processing overhead increase due to beamforming requirements and timing precision demands
Solution Approach 1:
The patent merges control information transmission with data channel transmission by multiplexing control information containers onto the data channel. Instead of using separate dedicated control channels, the control information is combined with data symbols in the same time-frequency resources, thereby reducing device complexity and processing overhead while maintaining transmission reliability through the established data channel protocols and beamforming operations.
2Productivity
If a dedicated control channel is used for control information transmission, then transmission reliability is ensured through dedicated resources, but resource utilization efficiency decreases due to unused bandwidth and time
Solution Approach 1:
The patent implements multi-functionality by allowing the data channel to serve dual purposes: transmitting both data information and control information through the control information container multiplexed onto the data channel. This universal approach eliminates dedicated control channel resources, thereby improving resource utilization efficiency while maintaining control information transmission reliability through the robust data channel transmission mechanisms and error correction coding.
3Ease of operation
If control information is transmitted without predefined container sizes, then flexibility in encoding is improved, but decoding complexity increases due to the need to determine container boundaries and sizes dynamically
Solution Approach 1:
The patent applies preliminary action by pre-defining a set of possible container sizes for control information before transmission. The transmitter selects an appropriate container size based on the amount of control information to be transmitted, and this size indication is conveyed to the receiver. This preliminary configuration eliminates the need for dynamic container boundary detection during decoding, thereby reducing decoding complexity while maintaining encoding flexibility through the predefined size options.
