Terminal Channel Occupancy Sharing for Heterogeneous Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, terminals with heterogeneous communication modules operating in the same frequency band experience unnecessary battery power consumption due to simultaneous channel sensing by WLAN and LAA communication modules in the unlicensed frequency band.
Innovation Solution
A control information utilization method and apparatus that allows terminals to share channel occupancy information using a licensed assisted access (LAA)-radio identifier, enabling one module to sense and share unlicensed band frequency occupancy status with the other module, thereby reducing unnecessary channel sensing and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both WLAN and LAA communication modules perform channel sensing in the unlicensed frequency band, then each module can independently determine channel occupancy status, but unnecessary battery power consumption occurs due to redundant sensing operations
Solution Approach 1:
The patent merges the channel sensing operations of WLAN and LAA communication modules by allowing them to share channel occupancy information. The LAA module performs channel sensing and determines channel occupancy status, then shares this information with the WLAN module, eliminating redundant sensing operations and reducing battery power consumption while maintaining reliable channel occupancy detection for both modules
Solution Approach 2:
The patent implements a universal channel occupancy information sharing mechanism where the LAA module's channel sensing capability serves both LAA and WLAN communication functions. By using the same channel occupancy information for both communication types, the system achieves multi-functionality without requiring separate sensing operations, thereby reducing energy consumption
2Productivity
If terminals with heterogeneous communication modules operate in the same frequency band, then frequency utilization efficiency is improved, but unnecessary battery power consumption occurs due to simultaneous channel sensing by multiple modules
Solution Approach 1:
The patent merges channel sensing operations across heterogeneous communication modules (WLAN and LAA) operating in the same frequency band. The LAA module performs channel sensing and shares channel occupancy information with the WLAN module, allowing both modules to operate efficiently in the unlicensed band without redundant sensing, thus improving frequency utilization while reducing power consumption

AI summary
A control information utilization method and an apparatus of a terminal with heterogenous technology communication modules operating in a same frequency band are provided to protect against unnecessary battery power consumption. A control information reception method of a terminal includes receiving control information from a base station using a first module, determining a channel occupancy time based on the control information using a licensed assisted access (LAA) radio identifier, and transferring the channel occupancy time to a second module that is operating in a same frequency band as the first module.
