Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current Device-to-Device (D2D) communication technologies, the initiating device lacks essential information about the target device, such as channel information, leading to inefficient D2D paging and communication.
Innovation Solution
A wireless communication device and method that utilize Location Area Code (LAC) information to determine if devices are in the same location or cell, with a base station sending paging signaling to assist in D2D communication, including information about dedicated carriers and channel allocation, enabling efficient D2D paging and communication.

Engineering Contradiction Analysis
1Reliability
If the base station notifies only two communication devices for D2D communication, then the base station can determine D2D communication pairs, but the initiating device lacks target device information (channel information, etc.), degrading D2D paging efficiency
Solution Approach 1:
The base station performs preliminary actions by pre-calculating and preparing paging signaling containing target device channel information before D2D communication is actually initiated. This allows the initiating device to obtain necessary target device information in advance, eliminating the information loss problem while maintaining reliable D2D communication setup.
Solution Approach 2:
The base station acts as an intermediary that bridges the information gap between communication devices. It generates and transmits paging signaling containing target device channel information to the initiating device, enabling the initiating device to perform efficient D2D paging without directly accessing target device information sources.
2Productivity
If D2D devices communicate directly over reused resources, then spectrum utilization efficiency improves, but the initiating device cannot obtain target device channel information, reducing subsequent D2D paging efficiency
Solution Approach 1:
The base station performs preliminary actions by pre-calculating and preparing paging signaling containing target device channel information before D2D communication is actually initiated. This allows the initiating device to obtain necessary target device information in advance, eliminating the information loss problem while maintaining reliable D2D communication setup.
Solution Approach 2:
The base station acts as an intermediary that bridges the information gap between communication devices. It generates and transmits paging signaling containing target device channel information to the initiating device, enabling the initiating device to perform efficient D2D paging without directly accessing target device information sources.
