Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beam-forming technologies fail to account for varying distances and distributions of communication nodes, leading to inefficient power utilization and resource allocation due to uniform beam transmission, which results in wasted resources for nodes with low path loss and insufficient resources for densely populated areas.
Innovation Solution
The method involves configuring and transmitting multiple pilot beams with distinct characteristics, such as varying transmit power, gain, and width, allowing communication nodes to select optimal beams based on calculated boosting values and channel quality, optimizing power and resource utilization.

1Ease of manufacture
If uniform beam transmission is used for all second communication nodes, then the system implementation is simple, but nodes with low path loss waste power resources while nodes with high path loss cannot obtain reliable measurement pilots
Solution Approach 1:
The patent applies local quality by configuring different beam parameters (transmit power, beam gain, beam width) for different spatial regions or groups of second communication nodes. Specifically, the first communication node divides the service area into multiple regions based on distance or spatial distribution, and transmits beams with optimized parameters tailored to each region's characteristics, ensuring reliable measurement pilots for all nodes regardless of their path loss conditions
Solution Approach 2:
The patent changes beam parameters (transmit power, beam gain, beam width, number of beams) based on the spatial distribution and path loss characteristics of second communication nodes. By dynamically adjusting these parameters for different regions or node groups, the system achieves reliable measurement pilots without requiring uniform high-power transmission to all nodes
