Base Station BWP Control Signal Parameter Reduction

Solution Overview

Problem

In 5G communication systems, the processing load of terminals increases due to the configuration of multiple Bandwidth Parts (BWPs) with various parameters, leading to higher computational complexity and power consumption.

Innovation Solution

A simplified BWP configuration method is introduced, where the base station generates and transmits a control signal with reduced parameter candidates, allowing the terminal to configure BWPs with less information, thereby reducing processing load and computational complexity.
