Uplink Transport Block Transmission Over Multiple Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing the transmission of transport blocks over multiple slots, particularly when a different uplink transmission is scheduled within the transport block, leading to conflicts and resource inefficiencies.
Innovation Solution
The system includes a method where user equipment (UE) and base stations exchange information to allocate resources for uplink transmissions of transport blocks over multiple slots, allowing for the transmission of coded bits based on scheduled uplink transmissions, which enables efficient handling of conflicts and reduces processing and memory resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transport block is transmitted over multiple slots, then the transmission reliability is improved, but the resource allocation complexity increases when another uplink transmission is scheduled within the transport block
Solution Approach 1:
The transport block transmission is segmented across multiple slots, allowing the system to divide the transmission resource allocation into discrete time units. This segmentation enables independent scheduling and management of each slot, reducing the overall complexity of resource allocation while maintaining transmission reliability through distributed transmission across multiple time resources.
2Productivity
If multiple uplink transmissions are scheduled within the transport block transmission period, then the system utilization is improved, but the conflict management complexity increases
Solution Approach 1:
The system performs preliminary scheduling of uplink transmissions by allocating specific slots for transport block transmission before other uplink transmissions are scheduled. This advance planning allows the scheduler to preemptively resolve potential conflicts by designating protected time resources, enabling higher system utilization without requiring complex real-time conflict management mechanisms.
3Productivity
If the transport block transmission occupies multiple slots, then the data throughput is improved, but the scheduling flexibility deteriorates when other transmissions are inserted
Solution Approach 1:
The scheduling system dynamically adjusts resource allocation based on traffic demands and channel conditions. When high throughput is required, the system allocates multiple consecutive slots for transport block transmission. When scheduling flexibility is needed, the system can insert other uplink transmissions in previously allocated slots by updating the scheduling decisions, allowing the system to adapt between throughput optimization and scheduling flexibility as conditions change.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information identifying a resource allocation for an uplink transmission of a transport block over multiple slots. The UE may transmit, to the base station, at least a portion of coded bits corresponding to the transport block based at least in part on a different uplink transmission being scheduled within the uplink transmission of the transport block over the multiple slots. Numerous other aspects are described.
