Solution Overview

Problem

Current wireless communication systems, particularly in LTE technology, face challenges in optimizing the time allocation for downlink and uplink grant information in control channels, which affects the efficiency and capacity of communication networks.

Innovation Solution

The method involves providing separate control channels for downlink and uplink grant information and adjusting the time apportioned for each, optimizing the time split between them to enhance communication efficiency and capacity, particularly by using a processing system to determine and manage the time allocation in control channels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If separate control channels are provided for downlink and uplink grant information, then the capacity and efficiency of communication networks are improved, but the device complexity increases

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidcontrol channel structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the control channel into separate downlink grant channels and uplink grant channels. This segmentation allows independent optimization of each channel type, enabling the system to handle downlink and uplink grants more efficiently without interfering with each other, thus improving overall communication efficiency despite the increased structural complexity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If time apportionment for downlink and uplink grant information is adjusted, then the adaptability and capacity of the system are improved, but the difficulty of detecting and measuring increases

Engineering Contradiction:
Improvetime allocation flexibilityVSAvoidtime measurement complexity
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent implements dynamic time apportionment for downlink and uplink grant information in control channels. The system can adjust the time allocation between downlink and uplink grants based on traffic conditions and network requirements, providing flexibility and adaptability. This dynamic adjustment mechanism allows the system to optimize resource utilization while managing the complexity of time measurement through structured procedures.
