Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, such as LTE, face challenges in reducing cost per bit, increasing service availability, and managing flexible frequency band use, while also requiring simplified structures and appropriate power consumption, especially as user demands and technological expectations continue to rise.
Innovation Solution
A method and apparatus for User Equipment (UE) in a wireless communication system that receives uplink scheduling information with an indicator for a network node, identifies the node, generates data units for supported services, and transmits these data units via indicated radio resources, allowing for efficient data transmission and management across multiple network nodes supporting different services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a UE transmits data for multiple services to multiple network nodes, then service availability increases, but device complexity and power consumption increase
Solution Approach 1:
The patent segments the data transmission process by service type. The UE identifies which network node supports which service, and transmits data for each service to the appropriate node. This segmentation allows the UE to manage multiple services systematically, reducing the complexity of handling all services simultaneously while maintaining high service availability through targeted transmissions to specialized network nodes.
2Productivity
If uplink scheduling information includes an indicator for network node identification, then data transmission efficiency improves, but message size and processing overhead increase
Solution Approach 1:
The patent extracts the network node identification indicator from the general uplink scheduling information structure. By including a dedicated indicator field that specifically identifies the target network node, the system enables efficient routing decisions without significantly expanding the overall message size. This extraction approach allows the UE to quickly identify the appropriate network node for data transmission while keeping the scheduling information compact and processed efficiently.
