Dynamic DRX Parameter Configuration for Bandwidth Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing discontinuous reception (DRX) configurations in communication technology have limited flexibility, leading to inefficient channel monitoring and increased power consumption due to semi-statically configured parameters.
Innovation Solution
A method and apparatus for dynamically configuring DRX parameters for designated bandwidth parts (BWP) by a base station, allowing for flexible DRX parameter settings, including DRX wake-up duration, inactivity timer, short and long cycles, and automatic BWP fallback, which are communicated to terminals for efficient power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If semi-static DRX parameters are configured, then configuration simplicity is maintained, but flexibility and channel monitoring efficiency deteriorate
Solution Approach 1:
The patent applies dynamics by enabling DRX parameters to change dynamically rather than remaining semi-static. The base station can adjust DRX parameters in real-time based on service types and channel conditions, with parameters becoming effective after BWP switching. This resolves the contradiction by making the system adaptable while managing complexity through automated dynamic adjustment mechanisms.
Solution Approach 2:
The patent implements parameter changes by allowing DRX parameters to be modified based on different service scenarios and channel conditions. The base station dynamically adjusts parameters such as drx-OnDuration, drx-Inactivity, and drx-Retransmission values, and these changes take effect after BWP switching. This enables flexibility while the base station manages the complexity of parameter adjustments.

AI summary
The present disclosure provides a method and apparatus for discontinuous reception (DRX) configuration. The method is applicable to a base station. The base station configures a corresponding designated DRX parameter for a designated BWP. The base station configures at least one bandwidth part (BWP) for a terminal. The base station generates a DRX configuration information for indicating that the designated DRX parameter is to be used on the designated BWP. The base station sends the DRX configuration information to the terminal for the terminal to use the designated DRX parameter on the designated BWP based on the DRX configuration information.
