Radio Coverage Information Transmission for UE Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently providing information about radio coverage, particularly in discontinuous coverage scenarios, which can lead to increased signaling overhead and power consumption for user equipment (UE), especially in non-terrestrial networks and scenarios where UEs have varying traffic profiles.
Innovation Solution
An apparatus and method where a network device transmits information characterizing the radio coverage of further network devices that temporarily and partially cover a neighbor area of a first radio cell, allowing UEs to adapt their sleep and wake-up periods based on their traffic profiles and operational requirements, using broadcasting to reduce signaling overhead and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a network device transmits detailed radio coverage information of further network devices to UEs, then UEs can adapt their sleep and wake-up periods to optimize power consumption, but the signaling overhead increases
Solution Approach 1:
The radio coverage information is segmented into essential parameters only (coverage area, time duration, frequency resources) rather than transmitting complete cell configuration data. This segmentation allows UEs to determine wake-up periods without receiving excessive signaling, resolving the contradiction between power optimization and overhead reduction.
Solution Approach 2:
The network device performs preliminary action by broadcasting coverage information in advance before UEs need to wake up. UEs can determine their wake-up periods from this pre-transmitted information without requiring additional real-time signaling, thus reducing ongoing signaling overhead while enabling power optimization.
2Ease of operation
If a network device provides comprehensive radio coverage information including position and timing of further network devices, then UEs can efficiently manage operational states, but the information transmission complexity increases
Solution Approach 1:
The patent extracts only the essential elements needed for UE operational management (coverage area, time duration, frequency resources) from the complete radio coverage information. By taking out only these critical parameters and omitting redundant details, the information transmission complexity is reduced while UE operational state management remains efficient.
Solution Approach 2:
The patent changes the parameter representation by using simplified indicators (e.g., coverage area identifiers, time duration values, frequency resource indicators) instead of transmitting complete cell configuration parameters. This parameter transformation reduces transmission complexity while maintaining the ability for UEs to manage their operational states effectively.
3Use of energy by moving object
If broadcasting is used to transmit radio coverage information to all UEs, then signaling overhead per UE is reduced, but the total network signaling load increases
Solution Approach 1:
The network device transmits broadcasting information with partial action by including only the minimum necessary coverage parameters rather than complete cell information. This partial transmission reduces the total network signaling load compared to full cell reconfiguration messages, while still enabling UEs to optimize their power consumption through accurate wake-up period determination.
