Idle-State Data Transmission Configuration to Reduce Paging Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular networks with dense deployments of low-power nodes, user equipment (UE) frequently switches channels for downlink synchronization, leading to high power consumption and inefficient resource utilization due to fixed cell deployments and frequent paging, which wastes downlink resources and increases network power consumption.
Innovation Solution
Implementing a data transmission method that utilizes idle-state transmission configuration information to optimize synchronization and paging processes, allowing nodes to perform efficient data transmission even when in an idle state, thereby reducing power consumption and resource wastage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network performs paging in many small cells to locate idle UE, then the network can find the UE, but downlink resources are wasted and network power consumption increases
Solution Approach 1:
The patent extracts the synchronization and paging functions from the traditional cell-specific infrastructure and consolidates them into a unified synchronization guide signal transmitted by the first node. This allows the network to page the UE through a single node rather than broadcasting across multiple small cells, thereby reducing downlink resource waste and network power consumption while maintaining reliable UE localization capability
Solution Approach 2:
The first node transmits synchronization guide signals that serve multiple functions simultaneously: providing downlink synchronization, carrying paging information, and enabling UE location identification. This multi-functional approach eliminates the need for separate paging transmissions in each small cell, reducing overall network energy consumption while maintaining paging reliability
2Measurement precision
If UE performs downlink synchronization in each small cell when entering, then synchronization accuracy is maintained, but UE power consumption increases due to frequent channel switching
Solution Approach 1:
The network configures the UE with synchronization guide signal parameters and transmission configuration information before the UE enters idle state. This preliminary configuration allows the UE to maintain synchronization without performing frequent downlink synchronization operations when moving between cells, thereby reducing UE power consumption while maintaining synchronization accuracy through the persistent synchronization guide signal from the first node
Solution Approach 2:
The patent merges the synchronization function with the paging function by transmitting both through the same synchronization guide signal from the first node. This consolidation eliminates the need for the UE to perform separate downlink synchronization operations in each small cell, reducing channel switching frequency and UE power consumption while maintaining synchronization accuracy through the unified signal
3Device complexity
If the network uses fixed cell deployment for synchronization and paging, then network结构简单 is maintained, but transmission efficiency decreases and resource utilization is poor
Solution Approach 1:
The patent introduces dynamic configuration of synchronization guide signal parameters and transmission configuration information, allowing the network to adaptively adjust synchronization and paging resources based on actual traffic conditions and UE locations. This dynamic approach improves transmission efficiency and resource utilization while maintaining relatively simple network structure through the centralized first node architecture
Solution Approach 2:
The network performs preliminary configuration of synchronization guide signal parameters and transmission configuration information before the UE enters idle state. This advance configuration enables more efficient resource allocation and improves transmission efficiency by preparing optimal parameters in advance, while the overall network structure remains simple through the centralized first node approach
