Multiplexing Control Data for Multiple Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems require additional resources and processing to support separate control channels for each data channel, which is inefficient and resource-intensive.
Innovation Solution
The method involves combining data rate information for multiple data channels, encoding it, and transmitting it via a single control channel, allowing the base station to decode and extract the necessary information for each channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate control channels are used for each data channel, then control information can be transmitted reliably, but resource usage and processing requirements increase
Solution Approach 1:
The patent combines control information from multiple data channels into a single control channel. The mobile station multiplexes control data for multiple data channels onto one control channel, reducing the number of separate control channels needed. This merging approach maintains reliable control information transmission while reducing processing requirements and resource usage at both the mobile station and base station.
Solution Approach 2:
The single control channel is designed to handle control information for multiple data channels simultaneously. By making the control channel universal and multi-functional, the system eliminates the need for dedicated control channels for each data channel, thereby reducing device complexity and processing requirements while maintaining the reliability needed for control information transmission.
2Reliability
If separate control channels are used for each data channel, then control information can be transmitted reliably, but resource usage increases
Solution Approach 1:
The patent merges control information from multiple data channels into a single control channel, reducing the quantity of resources needed. Instead of allocating separate control channels for each data channel, the system combines them, thereby reducing resource usage including processing power, memory, and communication resources while maintaining reliable control information transmission through proper error handling and acknowledgment mechanisms.
3Adaptability or versatility
If multiple control channels are used, then control information for each data channel can be transmitted independently, but system efficiency decreases
Solution Approach 1:
The patent combines control information for multiple data channels into a single control channel, improving system efficiency by reducing the number of separate transmission paths. The mobile station multiplexes control data efficiently, and the base station demultiplexes and processes it accordingly. This approach maintains the adaptability to handle different data channels independently through software-based processing while improving overall system productivity and efficiency.

AI summary
Systems and methods for communicating control data for multiple data channels using a single control channel. In one embodiment, a method is implemented in a WCDMA communications system. This method includes combining data rate information for a first data channel and data rate information for a second data channel in a mobile station, encoding the combined data rate information and transmitting the encoded combined data rate information from the mobile station to a base station via a single control channel. This method further includes receiving the encoded combined data rate information in the base station, decoding the encoded combined data rate information to produce the combined data rate information, and extracting the data rate information for the first and second data channels and decoding the first and second data channels using this information.
