Engineering Contradiction Analysis
1Productivity
If multiple transport blocks are transmitted in continuous downlink resources, then data throughput is improved, but the ability to adapt to changing channel conditions deteriorates
Solution Approach 1:
The patent divides the continuous downlink transmission into multiple transport blocks separated by scheduling gaps. Each transport block can be independently scheduled and adapted based on channel conditions, allowing the system to maintain high throughput while preserving adaptability. The scheduling gap enables the network to insert new transmissions or modify parameters for subsequent blocks.
Solution Approach 2:
The patent introduces dynamic scheduling where the presence and size of scheduling gaps can be adjusted based on channel conditions and traffic requirements. This allows the system to transition between continuous transmission (for good channel conditions) and interrupted transmission with re-scheduling (for changing conditions), making the throughput adaptable to varying channel states.
2Adaptability or versatility
If scheduling gaps are inserted between transport blocks, then adaptability to channel conditions is improved, but data latency increases
Solution Approach 1:
The patent allows dynamic modification of scheduling parameters including the size and position of scheduling gaps. By adjusting these parameters based on traffic priority and channel conditions, the system can minimize latency for time-sensitive traffic while maintaining sufficient gaps for adaptation when needed, thus balancing flexibility and timing requirements.
3Productivity
If control signals are transmitted during scheduling gaps, then resource allocation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent uses the existing downlink control channel infrastructure to carry scheduling information during gaps, making the control signaling mechanism multi-functional. The same physical downlink control channel (PDCCH) structure is used both for initial scheduling and for dynamic modifications during gaps, avoiding the need for separate signaling mechanisms and reducing overall system complexity.
