Multi-Slot Uplink Rate Matching With Per-Segment Interleaving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies face inefficiencies in multi-slot uplink shared channel transmissions, particularly in interleaving processes that become complex and less efficient when transmissions span multiple slots, leading to increased complexity and resource consumption for user equipment (UE).
Innovation Solution
Implementing a method for wireless communication that involves selecting and interleaving coded bits on a per slot or per segment basis for multi-slot transmission occasions, allowing for more efficient rate matching and reduced complexity in UE processes, thereby improving transmission quality and resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the interleaving process is applied to multi-slot PUSCH transmissions, then transmission performance is improved, but the complexity of the interleaving process increases and becomes less efficient
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 process across all slots, the system performs interleaving independently for each slot or segment, reducing the overall complexity while maintaining transmission performance benefits.
2Reliability
If the interleaving process is applied to multi-slot PUSCH transmissions, then transmission performance is improved, but the efficiency of the interleaving process decreases
Solution Approach 1:
By segmenting the interleaving operation into smaller per-slot or per-segment processes, the system improves efficiency through better resource utilization and reduced computational overhead, while still achieving the transmission performance benefits of interleaving.
Solution Approach 2:
The patent performs rate matching and selects coded bits in advance for each slot or segment before interleaving. This preliminary action prepares the data structure optimally, making the subsequent interleaving process more efficient and reducing overall processing time.
3Adaptability or versatility
If rate matching is performed for multi-slot transmissions, then resource allocation is improved, but the complexity of UE processes increases
Solution Approach 1:
The patent applies rate matching independently for each slot or segment rather than across the entire multi-slot transmission. This segmentation simplifies the UE processing complexity by breaking down a large complex operation into smaller, more manageable independent operations, while still achieving effective resource allocation.
Solution Approach 2:
Different rate matching parameters and configurations can be applied locally to each slot or segment based on specific channel conditions and resource availability, optimizing resource allocation for each local context without requiring complex global coordination.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of one or more sets of contiguous time domain resources for a multi-slot transmission occasion. The UE may select, for a communication on the multi-slot transmission occasion, coded bits of a plurality of coded bits on one of the per slot basis or the per segment basis, for each of a plurality of segments, each segment including one of the one or more sets of contiguous time domain resources and spanning across at least two slots. The UE may interleave the coded bits on one of the per slot basis or the per segment 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.
