Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In wireless communication systems, particularly in HSUPA and TD-SCDMA, there is a discrepancy in understanding between the network side and the UE side regarding Absolute Grant (AG) tables, leading to errors in radio resource scheduling.

Innovation Solution

A method where a base station control node indicates which AG table to use through signaling, ensuring that both the base station and the UE use the same AG table, thereby aligning their understanding and facilitating correct radio resource scheduling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple AG tables are used for different user categories, then the adaptability of resource scheduling is improved, but the complexity of maintaining consistent understanding between network side and UE side increases

Engineering Contradiction:

Improveresource scheduling adaptabilityVSAvoidAG table consistency management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base station control node pre-configures the AG table selection for both the base station and UE through signaling before resource scheduling occurs. This preliminary configuration ensures that both sides use the same AG table without requiring complex real-time synchronization mechanisms.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The base station receives signaling from the base station control node that provides feedback on which AG table should be used. This feedback mechanism ensures that the base station and UE maintain consistent understanding of the AG table selection across different user categories.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If the network side and UE side use different AG tables, then the flexibility in handling different user categories is improved, but the reliability of resource scheduling deteriorates

Engineering Contradiction:

Improveuser category handling flexibilityVSAvoidresource scheduling accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The base station control node acts as an intermediary that coordinates the AG table selection between the network side (base station) and the UE. Through signaling, it ensures both sides use the same AG table for their respective user categories, preventing scheduling errors while maintaining flexibility.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If manual configuration of AG tables is performed, then the precision of AG understanding alignment is improved, but the ease of operation deteriorates

Engineering Contradiction:

ImproveAG understanding alignmentVSAvoidAG table configuration operation

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The base station automatically obtains the AG table selection through signaling from the base station control node, eliminating the need for manual configuration. The system self-configures the AG table alignment, improving ease of operation while maintaining precision through the standardized signaling interface.

Inventive Principle:

Principle #25Self-service

AI summary

A radio resource scheduling method, apparatus and system are provided. The method includes: in a case that two or more Absolute Grant (AG) tables exist, a base station obtains an indication sent by a base station control node for indicating which AG table among the two or more AG tables is used by the base station, in which the AG table used by the base station as indicated in the indication is the same as an AG table used by a User Equipment (UE); and the base station performs High Speed Uplink Packet Access (HSUPA) radio resource scheduling for the UE according to the received indication sent by the base station control node. The technical solutions can ensure that the network side and the UE side have the same understanding about the granting information, thereby ensuring correct scheduling of radio resources.
