Paging Message Scheduling Adaptation to Terminal Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, the limited scheduling flexibility of paging messages due to varying terminal bandwidth capabilities leads to inefficient resource utilization and prolonged transmission times, especially when not all terminals have the required radio frequency bandwidths, affecting cell coverage and resource allocation.
Innovation Solution
A method where a network node acquires the operating bandwidth capability of terminal devices and sends paging messages accordingly, allowing for flexible scheduling by selecting the minimum or maximum bandwidth based on the terminal's capability, thereby optimizing message transmission and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If paging messages are sent using a fixed bandwidth allocation, then resource allocation is simplified, but scheduling flexibility is reduced and resource utilization becomes inefficient
Solution Approach 1:
The patent implements dynamic bandwidth allocation for paging messages by allowing the network to adjust the bandwidth based on the terminal's operating bandwidth capability. The paging message can be scheduled in different bandwidth parts (BWP) depending on the terminal's capability, transforming the static resource allocation into a dynamic adaptive system that resolves the contradiction between scheduling flexibility and resource allocation complexity.
Solution Approach 2:
The patent changes the bandwidth parameter of the paging message transmission to match the terminal's operating bandwidth capability. By adjusting this key parameter dynamically, the system achieves better adaptability without requiring completely new resource allocation mechanisms, thus balancing flexibility and complexity.
2Reliability
If paging messages are transmitted using maximum system bandwidth, then all terminals can receive messages, but transmission time is prolonged for terminals with smaller bandwidth capabilities
Solution Approach 1:
The patent applies local quality by transmitting the paging message in a bandwidth part that matches the specific terminal's operating bandwidth capability. Instead of using a uniform maximum bandwidth for all terminals, the system tailors the transmission bandwidth to each terminal's local capability, ensuring reliable reception while minimizing transmission duration for each specific case.
Solution Approach 2:
The patent segments the system bandwidth into different bandwidth parts (BWPs) and assigns the paging message to the appropriate BWP based on the terminal's capability. This segmentation allows the system to transmit paging messages efficiently to terminals with different bandwidth capabilities without requiring all terminals to wait for the maximum bandwidth transmission.
3Adaptability or versatility
If the system supports multiple terminal bandwidth capabilities, then device compatibility is improved, but resource allocation efficiency decreases
Solution Approach 1:
The patent implements a universal paging message transmission mechanism that can adapt to multiple terminal bandwidth capabilities through the use of bandwidth parts. The same paging message can be transmitted in different BWPs to serve terminals with different capabilities, achieving multi-functionality without requiring separate transmission systems for each terminal type, thus maintaining resource allocation efficiency.
