RLC Status Report Format Configuration for 5G NR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G NR communication systems, the current RLC layer status report mechanism leads to information redundancy and low transmission efficiency due to the inability to accurately decode multiple RLC layer data packets within a TTI, resulting in sequential packet loss and excessive bit usage for reporting sequence numbers.
Innovation Solution
A method and apparatus for determining and configuring the format of RLC status reports based on various criteria such as data radio bearer rate, bit requirements, packet transmission within a TTI, and device type, allowing flexible and scenario-specific reporting formats that reduce the number of bits needed for transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the current RLC layer status report mechanism is used in 5G NR, then reliable transmission is ensured, but information redundancy increases and transmission efficiency decreases
Solution Approach 1:
The patent applies dynamics by making the status report format configurable and adaptable rather than fixed. The receiver can dynamically select from multiple pre-configured formats based on actual transmission conditions, allowing the system to optimize between reliability and transmission efficiency in different scenarios.
Solution Approach 2:
The patent changes the parameter of status report format by introducing multiple configurable formats with different bit requirements. This allows the system to adjust the reporting granularity and bit usage based on actual packet loss conditions, reducing redundancy when packet loss is low while maintaining reliability when packet loss is high.
2Loss of information
If sequence numbers of multiple RLC layer data packets are reported sequentially, then all lost packets are identified, but the number of bits required for transmission increases excessively
Solution Approach 1:
The patent segments the status report into different formats with varying levels of detail. Instead of always reporting every individual packet sequence number, the system can use coarser segmentation (reporting only start sequence numbers and packet counts) when packet loss is minimal, reducing the quantity of bits transmitted while still identifying lost packets.
Solution Approach 2:
The patent applies partial action by reporting only the necessary information depending on the transmission condition. When packet loss is low, the system uses a simplified report format with fewer bits. When packet loss is high, it switches to a more detailed format that reports all sequence numbers, ensuring complete packet loss identification only when needed.
3Ease of manufacture
If a fixed RLC status report format is used, then implementation is simple, but transmission efficiency is low due to information redundancy
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple status report formats before actual transmission occurs. The receiver and sender agree on which format to use in advance, eliminating the need for complex real-time format negotiation while still enabling efficient adaptive reporting. This maintains implementation simplicity while improving transmission efficiency.
