Physical Channel Mapping Full-Duplex Non-Full-Duplex Symbols
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently mapping physical channels across full-duplex and non-full-duplex symbols, leading to suboptimal transmission and reception parameters, increased latency, and resource wastage due to failed decoding attempts and retransmissions.
Innovation Solution
The system ignores or schedules time domain resource allocations for physical channels that map to combinations of full-duplex and non-full-duplex symbols within a single slot, allowing for timing adjustments, filter changes, and optimal parameter settings, thereby enabling improved communication quality and resource conservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If physical channels are mapped across both full-duplex and non-full-duplex symbols in a slot, then resource utilization increases, but transmission reliability deteriorates due to failed decoding attempts and retransmissions
Solution Approach 1:
The patent segments the slot into distinct full-duplex symbol regions and non-full-duplex symbol regions, with physical channels mapped exclusively to one type of symbol at a time. This segmentation prevents the mixing of different duplex modes within a single physical channel transmission, thereby avoiding decoding failures while maintaining high resource utilization through dedicated resource pools for each duplex type.
2Reliability
If physical channels are mapped only to full-duplex or non-full-duplex symbols exclusively, then transmission reliability improves, but resource utilization decreases due to unused symbols
Solution Approach 1:
The patent implements dynamic resource allocation where the network can flexibly assign physical channels to either full-duplex or non-full-duplex symbol regions based on current channel conditions, traffic requirements, and duplex mode availability. This dynamic mapping ensures that symbols are never left unused while maintaining the reliability benefit of exclusive mapping, as each physical channel is assigned to the most appropriate symbol type for its specific transmission needs.
3Reliability
If timing adjustments and filter changes are implemented for full-duplex transitions, then communication quality improves, but system complexity increases
Solution Approach 1:
The patent incorporates timing adjustments and filter changes as pre-configured parameters that are prepared in advance for full-duplex symbol transitions. These adjustments are applied automatically at predetermined boundaries between full-duplex and non-full-duplex symbol regions, eliminating the need for complex real-time decision-making and reducing system complexity while maintaining high communication quality through optimized transition handling.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network, a time domain resource allocation associated with a physical channel that is mapped only to symbols associated with a full-duplex mode or only to symbols associated with a non-full-duplex mode in a slot. Alternatively, the UE may receive, from the network, a time domain resource allocation associated with a physical channel that is mapped only to symbols associated with a full-duplex mode or only to symbols associated with a non-full-duplex mode in a slot. The UE may further communicate with the network using the physical channel. Numerous other aspects are described.
