DRX Power-Saving Signaling for UE Data Transmission Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 3GPP has not yet determined how base stations and user equipment (UE) can save power during the period before the DRX-ON cycle in discontinuous reception (DRX), leading to inefficient data transmission and increased energy consumption.
Innovation Solution
Implementing a data transmission method that utilizes power saving signals or channels to manage UE power consumption by configuring specific parameters such as PS-RNTI, CSI-RS resources, and SRS resources, allowing the UE to efficiently transmit and receive data only when necessary, thereby optimizing power usage.

Engineering Contradiction Analysis
1Productivity
If data is transmitted in a conventional uplink-downlink configuration, then communication functionality is provided, but spectrum efficiency is low and resource utilization is insufficient
Solution Approach 1:
The patent applies universality by enabling uplink frequency resources to serve dual purposes: traditional uplink data transmission and downlink data transmission. This multi-functional use of frequency resources allows the same spectral resources to be utilized for both uplink and downlink communications, thereby improving spectrum efficiency without requiring additional dedicated downlink resources.
Solution Approach 2:
The patent implements dynamics through dynamic resource allocation where the network device dynamically configures and indicates to the terminal device which uplink frequency resources are allocated for downlink transmission. This dynamic adjustment allows flexible adaptation of resource usage based on traffic conditions, improving overall resource utilization while maintaining system flexibility.
2Productivity
If data is transmitted on uplink frequency resources, then resource utilization is improved, but interference between uplink and downlink signals may occur
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of network device control and coordination. The network device acts as a mediator that manages the shared uplink-downlink resources, scheduling transmissions and managing interference through centralized control. This intermediary coordination enables efficient resource sharing while mitigating potential interference between uplink and downlink signals.
3Productivity
If flexible resource allocation is implemented, then spectrum efficiency increases, but signaling overhead and configuration complexity increase
Solution Approach 1:
The patent applies partial action by implementing flexible resource allocation selectively rather than universally. The network device dynamically allocates downlink resources on uplink frequencies only when needed and when beneficial, rather than forcing flexible allocation in all scenarios. This selective approach achieves spectrum efficiency improvements while avoiding unnecessary signaling overhead in cases where traditional allocation suffices.
