Wireless Base Station Direct Link Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack a method for the wireless base station to effectively judge and manage direct communication between wireless terminals, leading to inefficient communication setups and increased processing load, power consumption, and frame exchange requirements.
Innovation Solution
The wireless base station observes reception frames from wireless terminals to determine the feasibility of direct communication by comparing reception electric field intensities and directional beam information, transmitting start or stop frames to initiate or terminate direct communication accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless terminal initiates direct communication setup, then the terminal can establish direct communication, but the processing load and power consumption at the terminal side increase
Solution Approach 1:
The wireless base station acts as an intermediary that observes reception frames between terminals and autonomously determines direct communication feasibility. By having the base station make the judgment instead of the terminal, the patent reduces the processing load and power consumption at the terminal while maintaining reliable direct communication establishment.
2Reliability
If the wireless terminal initiates direct communication setup, then the terminal can establish direct communication, but the construction scale of the wireless terminal increases
Solution Approach 1:
The base station serves as an intermediary that performs the complex judgment functions. The terminal only needs to transmit and receive frames without performing autonomous direct communication feasibility assessment, thereby reducing its construction scale while maintaining the ability to establish direct communication.
3Ease of operation
If the wireless base station autonomously determines direct communication feasibility, then the processing load at the terminal is reduced, but the base station must observe and analyze reception frames
Solution Approach 1:
The base station uses its existing frame reception and processing capabilities to autonomously determine direct communication feasibility. By leveraging its inherent functions to observe and analyze terminal communication frames, the base station can make autonomous decisions without requiring additional complex external systems, thereby reducing terminal operation complexity.
4Reliability
If direct communication is started under terminal initiative, then the terminal can establish direct communication, but the frame exchange amount increases
Solution Approach 1:
The base station acts as an intermediary that makes the direct communication feasibility determination, eliminating the need for additional terminal-initiated request frames. This reduces the overall frame exchange amount while maintaining reliable direct communication establishment through the base station's autonomous observation and decision-making.

AI summary
A wireless communication system including at least one wireless base station and two or more wireless terminals, and each of the wireless terminals can communicate with the wireless base station or directly communicate with another wireless terminal. The wireless base station observes reception frames from the wireless terminals, and transmits to one of the wireless terminals a start frame for starting direct communication of the wireless terminal concerned with another wireless terminal on the basis of the reception information of the reception frames.
