NR Receiving End Data Delivery Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the New Radio (NR) system, the need for ordered data delivery is not always necessary, leading to inefficiencies in data transmission, as existing methods require continuous data to be stored in buffers before delivery to the upper layer, which can cause delays and resource wastage.
Innovation Solution
A method and device that implement a first delivery mode where data is directly sent to the upper layer without buffering when it is not continuous, using a timer to determine continuity based on reordering window information, allowing for timely delivery and resource savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is buffered before delivery to ensure continuity, then data delivery order is maintained, but data delivery delay increases
Solution Approach 1:
The patent implements a dynamic delivery mode selection mechanism that switches between first delivery mode (direct delivery without buffering) and second delivery mode (ordered delivery with buffering) based on whether data continuity is required. This dynamic adaptation resolves the contradiction by applying the appropriate buffering strategy only when necessary, rather than always buffering or never buffering.
Solution Approach 2:
The patent changes the delivery parameter (buffering state) based on data continuity requirements. When data is continuous, buffering is applied to maintain order; when data is discontinuous, buffering is avoided to reduce delay. This parameter change approach allows the system to optimize between reliability and time loss based on actual data characteristics.
2Reliability
If data is buffered before delivery, then data continuity is ensured, but system resource consumption increases
Solution Approach 1:
The patent dynamically adjusts buffering resource allocation based on data continuity requirements. In the first delivery mode for discontinuous data, no buffering resources are consumed. In the second delivery mode for continuous data, buffering resources are allocated as needed. This dynamic resource management resolves the contradiction between ensuring data continuity and minimizing resource consumption.
3Reliability
If data is delivered in order, then data integrity is maintained, but real-time delivery capability is reduced
Solution Approach 1:
The patent implements dynamic delivery mode switching between first delivery mode (direct delivery for real-time performance) and second delivery mode (ordered delivery for integrity). The system selects the appropriate mode based on whether data continuity is required, thus resolving the contradiction between real-time delivery capability and data integrity.

AI summary
Embodiments of the present application provide a method and a device for transmitting data, which are capable of achieving timely data transmission. The method includes: starting, by a receiving end, a timer of a first delivery mode when determining that data delivered and data to be delivered are not continuous, where the first delivery mode is used to indicate that the receiving end directly delivers data to an upper layer upon the receipt of the data; and delivering, the receiving end, the data to be delivered to the high level using the first delivery mode in a case where the timer of the first delivery mode does not expire.
