Solution Overview

Problem

There is a need for improved techniques in 5G New Radio (NR) technology to efficiently switch between bandwidth parts (BWPs) at user equipment (UE) to optimize communication performance and power consumption.

Innovation Solution

A method and apparatus at the UE that allows for configuring multiple BWPs with specific parameter settings, enabling the UE to indicate its capability to reset certain BWP parameters and switch between them with varying delays, including a shortened switch delay for certain parameter changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the UE switches between BWPs with full parameter reconfiguration, then communication performance is optimized, but switching delay and power consumption increase

Engineering Contradiction:

Improvecommunication performanceVSAvoidswitching delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The BWP parameters are segmented into two groups: parameters to be reset (first group) and parameters to be maintained (second group). This segmentation allows selective reconfiguration, enabling faster switching by avoiding unnecessary parameter updates while maintaining communication performance for critical parameters.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of performing complete parameter reconfiguration during BWP switching, the UE applies partial action by resetting only the necessary parameters (first group) and maintaining others (second group). This reduces switching delay and power consumption while sufficient for optimized communication performance.

Inventive Principle:

Principle #16Partial or excessive action

2Reliability

If the UE switches between BWPs with full parameter reconfiguration, then communication performance is optimized, but power consumption increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The BWP parameters are segmented into two groups: parameters to be reset (first group) and parameters to be maintained (second group). This segmentation allows selective reconfiguration, enabling power savings by avoiding unnecessary parameter updates while maintaining communication performance for critical parameters.

Solution Approach 1:

The BWP parameters are segmented into two groups: parameters to be reset (first group) and parameters to be maintained (second group). This segmentation simplifies device complexity by providing a clear classification mechanism, enabling the UE to efficiently manage multiple BWP configurations through structured parameter organization.

AI summary

A method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, one or more BWP configurations for configuring a plurality of BWPs at the UE. The respective one or more BWP parameters of a set of BWP parameters define each respective BWP of the plurality of BWPs. The UE sends a capability indication indicating that the UE is capable of resetting values of one or more parameters of the set of BWP parameters. The UE sends a subset indication indicating that the UE is capable of resetting values of one or more parameters of a subset of BWP parameters from the set of BWP parameters.
