Solution Overview
Problem
In 5G mobile communication systems, the existing methods struggle to efficiently manage power state conversion durations for ultra-low latency and multiplexing of different traffic types, such as eMBB and URLLC, especially in short transmission time intervals, leading to increased latency and interference.
Innovation Solution
A method and apparatus for determining and implementing a time pattern for transmit power state conversion, which adjusts power states based on the position of sounding reference signals, data signals, and control signals in the time domain, and prioritizes power conversion durations to minimize interference and optimize transmission times for different traffic types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the TTI is shortened to achieve ultra-low latency, then the transmission latency is reduced, but the power state conversion duration occupies a larger proportion of the TTI, increasing the relative overhead and potentially affecting transmission efficiency
Solution Approach 1:
The patent implements dynamic power state conversion timing that adapts to different TTI lengths and traffic types. The network device determines specific power conversion durations based on the actual TTI configuration and traffic requirements, allowing the system to optimize the balance between latency reduction and power conversion overhead dynamically rather than using fixed conversion times
Solution Approach 2:
The patent changes the parameter of power state conversion duration to match different TTI configurations. By adjusting the power conversion time parameter based on the shortened TTI length and subcarrier spacing, the system ensures that power conversion overhead does not disproportionately consume the available transmission time while still achieving ultra-low latency
2Reliability
If power state conversion is performed continuously for SRS and data transmission to maintain signal quality, then transmission reliability is improved, but the cumulative power conversion duration increases, affecting the overall TTI utilization
Solution Approach 1:
The patent performs power state conversion in advance of signal transmission requirements. By determining the power conversion timing beforehand based on the TTI structure and signal requirements, the system prepares the power state optimally before SRS or data transmission begins, ensuring signal quality without adding unexpected conversion delays during the transmission window
Solution Approach 2:
The patent maintains continuous useful transmission action by optimizing power conversion timing to minimize interruptions. The system schedules power conversions at boundaries or during periods that do not interrupt critical signal transmission, ensuring that the useful transmission action remains continuous while still performing necessary power state changes
3Loss of time
If URLLC traffic is prioritized with higher transmission frequency to meet latency requirements, then the latency performance is improved, but the system bandwidth occupation increases, causing interference with eMBB traffic and reducing overall system capacity
Solution Approach 1:
The patent applies different power state conversion strategies to different traffic types locally. URLLC traffic receives optimized power conversion timing with shorter durations and higher priority scheduling, while eMBB traffic uses standard conversion timing. This local differentiation allows URLLC to achieve low latency without forcing all traffic to use the same conservative conversion parameters, thereby preserving overall system capacity
Solution Approach 2:
The patent segments the power state conversion process into traffic-type-specific configurations. By creating separate power conversion parameter sets for URLLC and eMBB traffic, the system can optimize each traffic type's conversion duration and timing independently, allowing URLLC to use aggressive short conversions while eMBB uses more conservative timing, thus maintaining both low latency for URLLC and high capacity for the system
