Terminal BWP Activation via Status Feedback

Solution Overview

Problem

The existing method for activating bandwidth parts (BWP) in 5G NR protocols, where the access network device autonomously configures frequency domain resources, often leads to excessive power consumption and overheating in terminals, failing to meet communication requirements.

Innovation Solution

The terminal proactively sends information to the access network device to request configuration or activation of frequency domain resources, allowing the access network device to configure or activate these resources based on the terminal's capabilities and status, thereby reducing power consumption and overheating.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the access network device autonomously configures or activates multiple frequency domain resource units (BWPs) to increase terminal bandwidth and peak rate, then the terminal can obtain larger bandwidth and higher peak rate, but the terminal experiences excessively high power consumption and overheating

Engineering Contradiction:

Improvepeak rateVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent makes the frequency domain resource configuration dynamic by allowing the terminal to actively report its current status (power consumption level, temperature, communication requirements) to the access network device. The access network device then dynamically adjusts the frequency domain resource configuration based on the terminal's real-time feedback, switching between different BWP configurations as needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces a feedback mechanism where the terminal reports its status information (power consumption, temperature, communication requirements) to the access network device. This feedback loop enables the access network device to make informed decisions about frequency domain resource allocation, balancing performance and power consumption based on actual terminal conditions.

Inventive Principle:

Principle #23Feedback

3Device complexity

If the access network device configures frequency domain resources autonomously without terminal input, then the configuration process is simple and fast, but the configured resources may not meet the terminal's actual communication requirements

Engineering Contradiction:

Improveconfiguration complexityVSAvoidadaptability to terminal requirements

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent enables the terminal to actively participate in the resource configuration process by having it report its own status and requirements to the access network device. This self-service approach allows the terminal to express its needs directly, improving the adaptability of the configuration while maintaining relatively simple overall system complexity.

Inventive Principle:

Principle #25Self-service

AI summary

A frequency domain resource activation method, a device, and a system, the method including determining, by a terminal, first information, where the first information includes at least one of information used to request that an access network device configure or activate a frequency domain resource unit of the terminal, or first assistance information of a frequency domain resource unit of the terminal, and where the frequency domain resource unit is a bandwidth part (BWP), and sending, by the terminal, the first information to the access network device.
