Solution Overview

Problem

Existing carrier aggregation technologies in 5G mobile communication systems face inefficiencies due to mismatched service processing abilities among component carriers, leading to low data transmission efficiency and increased time delays for user equipment.

Innovation Solution

A carrier management method that selects a primary cell for user equipment based on per-resource block throughput rather than solely relying on reference signal received power, optimizing the allocation of service data to improve transmission efficiency and reduce delays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If primary cell selection is based on reference signal received power, then cell selection is simple, but data transmission efficiency is low and time delays increase due to overloaded primary cells

Engineering Contradiction:
Improveprimary cell selection simplicityVSAvoiddata transmission efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent changes the selection parameter from reference signal received power to per-resource block throughput. This parameter change enables the system to identify component carriers with better actual data transmission capabilities, thereby improving data transmission efficiency while avoiding the overload problem that occurs when simply selecting based on signal strength

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the traditional signal-strength-based selection mechanism with a throughput-based selection mechanism. By substituting the selection criterion from physical layer signal measurement to higher-layer throughput measurement, the system achieves better resource allocation and avoids the congestion that results from uniform selection based on signal power

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Speed

If multiple user equipments select the same primary cell based on highest signal strength, then connection establishment is fast, but resource congestion increases and transmission efficiency decreases

Engineering Contradiction:
Improveconnection establishment speedVSAvoidresource distribution equity
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent introduces dynamic selection of primary cells based on real-time per-resource block throughput measurements. Instead of static selection based on signal strength, the system continuously adapts to changing channel conditions and load states, allowing user equipments to be distributed across multiple component carriers dynamically, thereby improving resource distribution equity while maintaining connection establishment speed

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent performs preliminary measurement and reporting of per-resource block throughput by user equipments before primary cell selection. This preliminary action provides the network with advance information about the actual transmission capabilities of different component carriers, enabling informed selection decisions that prevent resource congestion before it occurs

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If carrier aggregation is implemented without per-carrier throughput consideration, then system complexity is reduced, but service data allocation becomes mismatched and transmission efficiency is low

Engineering Contradiction:
Improvecarrier aggregation system complexityVSAvoidservice data transmission efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent implements feedback mechanisms where user equipments measure and report per-resource block throughput for different component carriers. The network uses this feedback information to make informed decisions about service data allocation and primary cell selection, creating a closed-loop system that continuously optimizes transmission efficiency without significantly increasing system complexity

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent segments the carrier aggregation system into distinct measurement, reporting, and decision-making components. By separating the throughput measurement function from the primary cell selection function, and by treating each component carrier independently in terms of throughput evaluation, the system achieves fine-grained resource allocation that improves transmission efficiency while maintaining manageable system complexity

Inventive Principle:
Principle #1Segmentation

AI summary

Embodiments of the present disclosure provide a carrier management method, a resource allocation method and related devices, relating to the technical field of communication. The carrier management method comprises: receiving an access request from a user equipment (UE); and, determining, from candidate component carriers (CCs), a primary cell (Pcell) of the UE based on the per-resource block (RB) throughput corresponding to each candidate CC. The resource allocation method comprises: acquiring at least one candidate allocation strategy for allocating service data to be allocated to at least one candidate CC; determining throughout information and transmission delay related information corresponding to the at least one candidate allocation strategy; determining a target allocation strategy based on the throughput information and the transmission delay related information; and, allocating the service data to be allocated based on the target allocation strategy.
