HSDPA HSUPA Frame Size Alignment With Scheduling Intervals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly those supporting HSDPA/HSUPA services, face inefficiencies and performance issues due to mismatched frame sizes and scheduling intervals, leading to time lags and increased costs associated with implementing base stations.
Innovation Solution
The method involves adjusting the frame size of data transmitted over signaling interfaces (Iub and Iur) to correspond with the scheduling interval, ensuring that the frame size is less than or equal to the interval, thereby optimizing data transfer and reducing the need for large memory buffers in base stations.

Engineering Contradiction Analysis
1Quantity of substance
If the frame size of data transmitted over signaling interfaces is larger than the scheduling interval, then the data transfer capacity is improved, but time lags occur and memory buffer requirements increase
Solution Approach 1:
The patent segments the data transmission by aligning the frame size with the scheduling interval, dividing the data flow into manageable chunks that can be processed and transmitted within each scheduling cycle. This prevents accumulation of data and reduces time lags between transmission cycles.
Solution Approach 2:
The patent dynamically adjusts the frame size to match the scheduling interval, making the system adaptive to varying traffic conditions. By synchronizing frame boundaries with scheduling decisions, the system optimizes data transfer efficiency while minimizing buffer requirements and time delays.
2Quantity of substance
If the frame size of data transmitted over signaling interfaces is larger than the scheduling interval, then the data transfer capacity is improved, but implementation costs increase due to larger memory buffers
Solution Approach 1:
The patent segments data transmission into frames that align with scheduling intervals, reducing the need for large memory buffers to store pending data. By processing data in smaller, synchronized units, the system lowers buffer requirements and associated implementation costs.
Solution Approach 2:
The patent changes the frame size parameter to match the scheduling interval, optimizing the balance between data transfer capacity and memory buffer requirements. This parameter alignment reduces the amount of data that needs to be buffered, thereby reducing device complexity and implementation costs.
3Adaptability or versatility
If the frame size does not correspond with the scheduling interval, then flexibility in data transmission is maintained, but efficiency and performance of HSDPA/HSUPA networks deteriorate
Solution Approach 1:
The patent dynamically synchronizes frame size with the scheduling interval to optimize network efficiency while maintaining adaptability. By aligning frame boundaries with scheduling decisions, the system achieves both high productivity and flexibility in handling varying traffic conditions.
Solution Approach 2:
The patent creates a universal framework where frame size adaptation works across different scheduling intervals and traffic conditions. This multi-functional approach maintains transmission flexibility while optimizing network efficiency through synchronized data transfer.

AI summary
A method of communication, generally, and more particularly, a method of wireless communication. The method includes the step of receiving at least data over a signaling interface. The received data may be received, for example, by a base station or base station controller. The method also includes the step of transmitting the data within a scheduling received data may also be characterized as having a frame size. The interval. The base station or base station controller, for example, may perform the step of transmitting the data. The frame size of the data received by the base station and/or base station controller may at most correspond with the scheduling interval such that frame size of the data may be less than or equal to the scheduling interval.
