Solution Overview

Problem

Current wireless communication systems face challenges in efficiently managing multiple concurrent service transmissions within a single cell, particularly due to the limitations of BWP switching delays and the restriction of multiple transmissions to a single activated BWP, which affects user experience and service transmission efficiency.

Innovation Solution

The implementation of First Type Frequency Resources (FTFRs) and Second Type Frequency Resources (STFRs) allows for simultaneous activation and configuration of multiple frequency resources, enabling seamless communication using FTFRs and their associated STFRs without switching delays, by mapping and coordinating these resources within the network and user equipment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If BWP switching is used to manage multiple service transmissions, then service transmission flexibility is improved, but switching delays increase and transmission efficiency deteriorates

Engineering Contradiction:
Improveservice transmission flexibilityVSAvoidswitching delays
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent segments frequency resources into multiple BWPs (Bandwidth Parts) that can be simultaneously activated and configured. Instead of switching between single activated BWP, the system divides the frequency spectrum into multiple independent resource blocks, each capable of carrying different service transmissions. This segmentation allows parallel service delivery without switching delays while maintaining the flexibility to allocate resources dynamically based on service requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single-dimension BWP activation model (one BWP at a time) to a multi-dimensional resource allocation model where multiple BWPs are activated simultaneously across different frequency domains. This dimensional expansion allows the system to manage multiple service transmissions in parallel by allocating different BWPs to different services, eliminating the need for time-consuming switching operations while preserving transmission flexibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If only a single BWP is activated for transmission, then resource management complexity is reduced, but concurrent service transmission capability is limited

Engineering Contradiction:
Improveresource management complexityVSAvoidconcurrent service transmission capability
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent implements multi-functionality by enabling each BWP to serve multiple purposes simultaneously. Different BWPs can be allocated to different service types (e.g., eMBB, URLLC, mMTC) based on their specific requirements. The system maintains a unified resource management framework that can dynamically assign and reassign BWPs to various services, allowing a single BWP configuration system to handle diverse service transmissions without increasing operational complexity for the end user.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces dynamic BWP allocation and activation mechanisms where the network can flexibly configure and activate multiple BWPs based on real-time service demands. The system dynamically adjusts BWP parameters such as frequency location, bandwidth size, and subcarrier spacing according to service requirements. This dynamic capability enables concurrent service transmissions while maintaining manageable complexity through automated resource orchestration and adaptive configuration.

Inventive Principle:
Principle #15Dynamics

3Productivity

If multiple BWPs are simultaneously activated, then concurrent service transmission efficiency is improved, but resource coordination complexity increases

Engineering Contradiction:
Improveconcurrent service transmission efficiencyVSAvoidresource coordination complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements feedback mechanisms where the network continuously monitors the status and performance of multiple activated BWPs. Based on this feedback, the system dynamically adjusts resource allocation, activates or deactivates specific BWPs, and optimizes transmission parameters. The feedback loop includes service quality metrics, resource utilization data, and interference levels, enabling the network to maintain efficient concurrent transmissions while managing coordination complexity through real-time adaptation and automated decision-making.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary resource coordination layer that manages the interaction between multiple activated BWPs. This intermediary mechanism handles resource allocation, conflict resolution, and coordination tasks, shielding individual service transmissions from the complexity of multi-BWP management. The coordinator acts as a mediator that assigns time-frequency resources, resolves interference between BWPs, and ensures efficient utilization of concurrent transmissions without requiring each service to directly manage the complexity of the entire BWP set.

Inventive Principle:
Principle #24Intermediary (Mediator)
