Multi-Slot Uplink Interleaving with Per-Slot Bit Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently interleaving coded bits across multiple slots for multi-slot uplink shared channel transmissions, leading to increased complexity and resource consumption in user equipment (UE).
Innovation Solution
A method for wireless communication that involves receiving an indication of contiguous time domain resources for a multi-slot transmission occasion, selecting coded bits on a per slot or per segment basis, interleaving these bits, and transmitting the interleaved encoded bit sequences. This approach simplifies the interleaving process by dividing the transmission into manageable slots or segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the interleaving process is applied to multi-slot transmissions, then transmission performance is improved, but complexity and resource consumption increase
Solution Approach 1:
The patent divides the multi-slot transmission into separate interleaving processes for each slot or segment. Instead of applying a single complex interleaving operation across all slots, the system performs independent interleaving operations on individual slots or segments, thereby reducing overall complexity while maintaining transmission performance benefits.
2Reliability
If the interleaving process is applied to multi-slot transmissions, then transmission performance is improved, but resource consumption increases
Solution Approach 1:
By segmenting the interleaving operation into smaller per-slot or per-segment processes, the patent reduces the computational burden and associated power consumption. Each segment processes fewer bits independently, which lowers the energy required compared to a monolithic interleaving operation across the entire multi-slot transmission.
3Ease of operation
If coded bits are selected on a per transmission occasion basis, then simplicity is maintained, but adaptability to different slot configurations is reduced
Solution Approach 1:
The patent introduces dynamic adaptability by allowing the interleaving behavior to change based on slot configuration. The system can dynamically select between different interleaving modes (per-slot, per-segment, or per-transmission-occasion) depending on the specific transmission scenario, thereby maintaining both simplicity when appropriate and adaptability when needed.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, for a communication on a multi-slot transmission occasion, coded bits of a plurality of coded bits on a per slot basis, for each of multiple slots of the multi-slot transmission occasion. The UE may interleave the coded bits on a per slot basis to form one or more interleaved encoded bit sequences of a codeblock. The UE may transmit the communication including the one or more interleaved encoded bit sequences. Numerous other aspects are provided.
