Solution Overview
Problem
Current multicarrier communication systems face challenges in efficiently managing data multiplexing and radio resource allocation across diverse wireless devices and base stations, particularly in next-generation networks, where dynamic modulation and coding schemes are needed to adapt to varying radio conditions.
Innovation Solution
The implementation of advanced Radio Access Network (RAN) architectures with next-generation Node B (gNB) and evolved Node B (ng-eNB) nodes, utilizing New Radio (NR) protocols, enables dynamic radio resource management, scheduling, and data multiplexing through advanced protocol stacks and interfaces like NG-U and NG-C, supporting hybrid transmission mechanisms and adaptive modulation schemes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple uplink grants are received during a single time duration, then data transmission throughput increases, but processing complexity and timing conflict increase
Solution Approach 1:
The patent applies preliminary action by determining a processing order for multiple uplink grants before actual transmission occurs. The MAC entity receives multiple grants during a single time duration and establishes a predetermined processing sequence based on grant indices or other criteria, allowing the system to handle multiple grants systematically without timing conflicts or excessive complexity during execution.
2Adaptability or versatility
If dynamic modulation and coding schemes are implemented, then adaptability to radio conditions improves, but system complexity increases
Solution Approach 1:
The patent implements dynamics by enabling the MAC entity to dynamically select and process specific uplink grants from multiple received grants based on current radio conditions and transmission requirements. The system can adaptively choose which grants to execute and in what order, allowing flexible response to varying channel quality while maintaining manageable complexity through structured selection criteria.
Data Source
AI summary
A wireless device receives uplink grants indicating resources of cells. First uplink grants of the uplink grants are processed as a group according to an order. The group is based on the first uplink grants being received during one or more coinciding time durations that the wireless device is configured to monitor at least one control channel for the cells. The processing comprises multiplexing data of one or more logical channels into transport blocks based on the first uplink grants. The transport blocks are transmitted based on the first uplink grants.
