Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in transmitting small amounts of data when a wireless device is in a non-connected state, leading to increased retransmissions and power consumption, and lack the ability to adapt transmission types based on variables like channel conditions and data volume.
Innovation Solution
Implementing a communication procedure that allows for the selection and change of transmission types, such as between configured grants and random access procedures, to accommodate varying conditions and transition to a connected state for further data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a wireless device uses a fixed transmission type for small data transmission in non-connected state, then the device complexity is reduced, but the productivity decreases due to increased retransmissions and inability to adapt to changing conditions
Solution Approach 1:
The patent implements dynamic transmission type selection where the wireless device can switch between configured grant transmission and random access procedure based on current channel conditions, data volume, and traffic load. This dynamic adaptation allows the system to optimize transmission efficiency without requiring complex manual configuration, resolving the contradiction between simplicity and productivity.
Solution Approach 2:
The system changes transmission parameters (transmission type) based on varying conditions such as channel quality, data volume thresholds, and network traffic load. By monitoring these parameters and adjusting the transmission type accordingly, the system achieves high productivity while maintaining relatively simple device complexity through automated parameter adjustment.
2Ease of operation
If a wireless device uses configured grant transmission for small data, then the ease of operation is improved, but the loss of time increases due to inability to adapt to changing channel conditions
Solution Approach 1:
The patent incorporates feedback mechanisms where the wireless device monitors channel conditions, data volume, and transmission outcomes. Based on this feedback, the device automatically adjusts the transmission type (configured grant or random access) to minimize retransmissions and delay, thereby maintaining ease of operation while reducing time loss through adaptive retransmission strategies.
3Reliability
If a wireless device transitions to connected state for data transmission, then the reliability is improved, but the use of energy increases due to connection establishment overhead
Solution Approach 1:
The system dynamically changes the transmission state parameter (connected or non-connected) based on data volume thresholds and channel conditions. For small data volumes, the device remains in non-connected state using configured grant or random access to save energy. For larger or more critical data, it transitions to connected state to ensure reliability, thus optimizing the trade-off between energy consumption and transmission reliability.
4Adaptability or versatility
If a wireless device uses random access procedure for transmission, then the adaptability is improved, but the loss of time increases due to procedure overhead
Solution Approach 1:
The patent implements dynamic selection between configured grant and random access procedures based on real-time conditions. When channel conditions are good and data volume is small, configured grant is used to avoid random access overhead. When adaptability is needed for varying conditions, random access is selected despite its time overhead, thus achieving the balance between adaptability and time efficiency through dynamic procedure selection.

AI summary
A communication procedure (e.g., a small data transmission (SDT) procedure) may be used for data transmission under certain scenarios. The communication procedure may facilitate transmission of small amounts of data, for example, even if a wireless device is in a non-connected state with respect to a network. Data transmission during the communication procedure may be based on a selected transmission type and the transmission type may be changed during the communication procedure.
