Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in managing the allocation and transmission of transport blocks (TBs) across multiple time slots, leading to data loss, increased latency, and resource wastage due to varying resource allocations and transmission types.
Innovation Solution
The communication device determines a starting bit for each time slot based on factors like symbol number, resource blocks, and redundancy version to efficiently allocate TB bits across multiple time slots, enabling reliable and low-latency transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If TB is transmitted over multiple time slots with varying resource allocations, then transmission flexibility and adaptability are improved, but data loss and transmission reliability deteriorate
Solution Approach 1:
The transport block is segmented into multiple code blocks, each assigned to specific time slots with determined starting bits. This segmentation allows flexible resource allocation across multiple time slots while maintaining reliable transmission through systematic bit distribution and redundancy version management for each segment.
Solution Approach 2:
The starting bit position for each time slot is determined in advance before transmission begins. This preliminary determination of starting bits, based on resource allocation and redundancy versions, ensures that each time slot knows its exact transmission boundaries, preventing data loss and maintaining reliability while allowing flexible resource usage.
2Productivity
If TB transmission spans multiple time slots, then resource utilization is improved, but latency increases
Solution Approach 1:
The transmission continues across multiple time slots without interruption, with each slot transmitting a portion of the TB starting from predetermined starting bits. This continuous transmission approach maximizes resource utilization by keeping the channel active while managing latency through efficient starting bit determination that minimizes gaps and retransmissions.
3Manufacturing precision
If starting bit determination is performed for each time slot, then transmission precision and reliability are improved, but computational complexity increases
Solution Approach 1:
The starting bit position is determined by changing parameters such as resource allocation size, time slot index, and redundancy version. Instead of complex calculations, the system uses parameter-based determination where starting bits are derived from these varying parameters, achieving precise transmission allocation with reduced computational complexity.
Solution Approach 2:
Each time slot automatically determines its own starting bit position based on its resource allocation and slot index, without requiring complex centralized coordination. This self-service approach achieves precise transmission positioning while minimizing overall system computational complexity through distributed, simple calculations.

AI summary
Methods, systems, and devices for wireless communications are described. A device may receive a resource allocation for transmitting a transport block (TB) over a set of time slots. The TB may include a set of coded bits. In some aspects, the device may determine starting indexes of subsets of the coded bits, each subset of the coded bits may be for transmission during a respective subset of time slots. In some other aspects, the device may receive a configured grant for a transmission of the TB over the set of time slots. In other aspects, the device may scale a size of the TB based on a first value independent of a second value associated with a number of time slots associated with the set of time slots.
