Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face high protocol overhead, particularly for voice traffic, due to large headers in packets, which can be inefficient and resource-intensive.
Innovation Solution
Implementing a voice-based data radio bearer with configurable parameters to generate transport blocks, including voice-specific settings, such as robust header compression and separate transmission of headers and payloads, to reduce overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard protocol headers are used in packets, then communication reliability is maintained, but protocol overhead increases significantly for voice traffic
Solution Approach 1:
The patent segments the protocol header into multiple parts: a standard header portion and a voice-specific header portion. The voice-specific portion contains optimized fields for voice traffic characteristics, allowing the system to maintain necessary protocol functionality while reducing overall header size and overhead for voice packets.
Solution Approach 2:
The patent applies local quality by creating voice-optimized header fields that are specifically tailored for voice traffic characteristics. Instead of using generic headers for all traffic types, the system implements specialized header structures with appropriate field lengths and formats that match voice traffic patterns, thereby reducing overhead while maintaining reliability.
2Reliability
If large protocol headers are used, then communication coverage and reliability are improved, but resource usage increases and link budget deteriorates
Solution Approach 1:
The patent extracts and removes unnecessary or redundant header fields that are not essential for voice traffic. By identifying and eliminating superfluous protocol elements, the system reduces the total header size, thereby conserving radio resources and improving the link budget without compromising the essential communication coverage and reliability.
Solution Approach 2:
The patent changes protocol parameters specifically for voice traffic, such as reducing header field lengths, optimizing data representation formats, and adjusting protocol configuration parameters. These parameter changes decrease the overall packet size and resource consumption while maintaining the necessary communication coverage and reliability for voice services.
3Adaptability or versatility
If standard data radio bearer configuration is used, then system compatibility is maintained, but voice traffic efficiency is reduced due to excessive overhead
Solution Approach 1:
The patent implements a universal header structure that can accommodate multiple traffic types while providing voice-optimized modes. The system maintains compatibility with standard protocols through a base header structure that works for all traffic types, while introducing voice-specific optimizations that activate when voice traffic is detected, thereby achieving both system compatibility and voice traffic efficiency.
Solution Approach 2:
The patent introduces dynamic header configuration that adapts based on traffic type. The system can dynamically switch between standard header formats for general traffic and optimized voice-specific header formats for voice traffic. This dynamic adaptation allows the system to maintain compatibility while efficiently optimizing performance for voice communications.

AI summary
Methods, systems, and devices for wireless device are described. A wireless device may receive a configuration for a data radio bearer associated with voice traffic in a wireless communications network. In some examples, the configuration may indicate one or more parameters associated with the voice traffic. Additionally, or alternatively, the wireless device may receive a configuration for a data radio bearer and a configured grant associated with voice traffic. The wireless device may identify a mapping between a configured grant identifier and the data radio bearer based on the configuration In some examples, the wireless device may generate a transport block including the voice traffic based on the one or more parameters associated with the voice traffic or the mapping between the configured grant identifier and the data radio bearer. The wireless device may then transmit the generated transport block including the voice traffic.
