Solution Overview

Problem

Current 5G NR technologies lead to inefficient bandwidth utilization and increased power consumption in user equipment (UE) due to network-based bandwidth part selection, which does not account for the prevailing or anticipated operational needs of the UE, resulting in suboptimal data transfer speeds and battery drain.

Innovation Solution

User equipment (UE) transmits operational information to the network, allowing the network to select and switch bandwidth parts based on the UE's current or anticipated needs, enabling more efficient resource utilization and improved battery conservation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the network selects bandwidth parts based on past operational needs, then the network can manage bandwidth resources, but the data transfer speed becomes suboptimal during heavy traffic periods

Engineering Contradiction:
Improvedata transfer speedVSAvoidbandwidth part selection adaptability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent inverts the traditional network-based bandwidth part selection approach by enabling the UE to autonomously select bandwidth parts based on its own operational needs. The UE determines whether to monitor a first or second bandwidth part based on local conditions such as traffic patterns, thereby making the selection process adaptive to real-time needs rather than relying on network decisions based on past behavior.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The UE performs self-service by autonomously selecting bandwidth parts without requiring network intervention for each selection decision. The UE monitors its own operational needs and independently determines the appropriate bandwidth part to monitor, reducing latency and improving responsiveness to changing traffic conditions.

Inventive Principle:
Principle #25Self-service

2Use of energy by moving object

If the network instructs the UE to monitor a fixed bandwidth part, then the network can simplify resource allocation, but the UE experiences increased power consumption during low traffic periods

Engineering Contradiction:
Improvepower consumptionVSAvoidbandwidth part selection complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent introduces dynamic bandwidth part selection where the UE can switch between monitoring a first bandwidth part during high traffic periods and a second bandwidth part during low traffic periods. This dynamic adaptation allows the system to optimize power consumption by selecting appropriate monitoring bandwidth based on current operational conditions rather than using a fixed configuration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The UE changes operational parameters by selecting different bandwidth parts based on traffic conditions. During heavy traffic, the UE monitors a first bandwidth part with appropriate characteristics for high data rates, while during low traffic periods, it switches to a second bandwidth part that consumes less power, thereby adapting system parameters to current needs.

Inventive Principle:
Principle #35Parameter changes

3Speed

If the UE monitors a wide bandwidth continuously, then the data transfer speed remains high, but the battery life decreases due to constant power consumption

Engineering Contradiction:
Improvedata transfer speedVSAvoidbattery life
Core Design Contradiction:
SpeedVSDuration of action of stationary object

Solution Approach 1:

The patent segments the available bandwidth into multiple bandwidth parts (first bandwidth part and second bandwidth part) with different characteristics. The UE selectively monitors only the necessary portion based on current traffic conditions, rather than continuously monitoring the entire wide bandwidth. This segmentation allows the UE to maintain high data transfer speeds when needed while conserving battery life during low traffic periods.

Inventive Principle:
Principle #1Segmentation

AI summary

A user equipment transmits user equipment information, associated with a communication of the user equipment, to permit a base station to select a first bandwidth part, a second bandwidth part, or a third bandwidth part. The user equipment is configured to communicate by the first bandwidth part, the second bandwidth part, and the third bandwidth part. The user equipment receives, from the base station, an instruction to monitor the first bandwidth part, the second bandwidth part, or the third bandwidth part. The instruction is selected based on the user equipment information. The user equipment monitors, based on the instruction, the first bandwidth part, the second bandwidth part, or the third bandwidth part.
