Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE and NR wireless communication mechanisms face challenges in managing power consumption and activation delays of multiple active carriers and panels at user equipment (UE), leading to suboptimal data transmission rates and user experience.
Innovation Solution
Implement methods and apparatuses for dynamic and flexible radio frequency (RF) utilization by providing activation information, including synchronization, beam management, and automatic gain control settings, to quickly activate carriers and panels, reducing activation delays and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple carriers and panels are activated to increase data transmission rate, then throughput is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic activation and deactivation of carriers and panels based on real-time traffic conditions. The network device receives traffic indication information from the UE, determines the appropriate number of carriers and panels needed, and sends activation/deactivation indications accordingly. This dynamic adjustment allows the system to optimize throughput while minimizing power consumption by activating only the necessary number of carriers and panels rather than keeping all active continuously.
2Use of energy by moving object
If carriers and panels are deactivated to save power, then power consumption is reduced, but activation delay increases when rapid transmission rate adjustment is needed
Solution Approach 1:
The patent implements a preliminary action mechanism where the network device receives traffic indication information in advance from the UE before actual data transmission begins. Based on this early indication, the network device proactively determines the required number of carriers and panels and sends activation indications ahead of time. This preliminary activation preparation reduces the effective activation delay when rapid transmission rate adjustment is needed, as the carriers and panels are activated just before data transmission begins rather than waiting for traffic to accumulate.
