Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in efficiently managing simultaneous transmissions over multiple channels, leading to conflicts and potential failures in receiving high-priority communications due to inadequate multiplexing or prioritization techniques.
Innovation Solution
A method and apparatus for determining whether to multiplex or prioritize communications scheduled for simultaneous transmission over different channels, based on channel priorities and parameters such as resource overlap, modulation schemes, and scheduling grants, to reduce the likelihood of base station failure in receiving high-priority communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If simultaneous transmissions are scheduled over multiple channels without multiplexing or prioritization, then channel utilization is maximized, but reliability of high-priority communications deteriorates due to conflicts and potential failures
Solution Approach 1:
The patent segments communications into different priority levels (high-priority and low-priority communications) and applies different handling mechanisms to each segment. High-priority communications are protected through prioritization rules that prevent multiplexing with low-priority communications when conflicts occur, while low-priority communications can be multiplexed when resources are available. This segmentation resolves the contradiction by ensuring reliability for critical communications while maintaining channel utilization through multiplexing of non-critical traffic.
Solution Approach 2:
The patent changes the parameter of transmission handling by introducing dynamic multiplexing decisions based on priority levels and resource overlap conditions. The system adjusts whether to multiplex or prioritize transmissions by evaluating parameters such as resource overlap, channel priorities, and communication types. This parameter-based dynamic adjustment allows the system to maximize channel utilization when resources are sufficient while protecting high-priority communications when conflicts arise.
2Productivity
If multiplexing is applied to simultaneous transmissions, then resource efficiency is improved, but complexity of determining transmission priorities increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing priority levels for different channels and communication types before conflicts occur. The system configures priority relationships in advance (e.g., uplink control information has higher priority than uplink data) and uses these pre-defined rules to make multiplexing decisions. This approach improves resource efficiency through automated multiplexing while reducing the complexity of real-time priority determination by relying on pre-configured rules rather than complex real-time analysis.
3Reliability
If prioritization is applied to ensure high-priority communications are received, then reliability is improved, but channel utilization decreases due to reduced multiplexing opportunities
Solution Approach 1:
The patent applies partial action by selectively multiplexing only those communications that do not create conflicts with high-priority transmissions. The system multiplexes low-priority communications with high-priority communications when resource overlap is minimal or non-existent, but prevents multiplexing when conflicts would compromise high-priority communication reliability. This partial multiplexing approach maintains high channel utilization for non-conflicting traffic while ensuring reliability for high-priority communications through selective prioritization.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may determine whether to multiplex or prioritize a first communication and a second communication that are scheduled for simultaneous transmissions via a first channel and a second channel, respectively. The mobile station may transmit one or more of the first communication or the second communication based at least in part on the determination of whether to multiplex or prioritize the first communication and the second communication. Numerous other aspects are provided.
