UE UCI Multiplexing Timing Condition Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies, such as those supporting 5G new radio (NR), face challenges in efficiently processing uplink control information (UCI) due to stringent timing conditions, which can limit the ability to multiplex different types of information in uplink transmissions, leading to resource inefficiencies and increased latency.
Innovation Solution
The proposed solution involves determining specific timing conditions for processing and transmitting UCI, allowing for the multiplexing of multiple types of information in a single uplink transmission if certain conditions are met, with relaxation of baseline timing rules to accommodate different UE processing capabilities and resource allocations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If baseline timing conditions are applied to UCI processing requests, then processing time is reduced, but the ability to multiplex different information types is limited
Solution Approach 1:
The patent implements dynamic timing condition evaluation by determining whether relaxed or baseline timing conditions apply based on the specific transmission scenario. The UE dynamically selects between different timing requirements (first set for relaxed, second set for baseline) depending on whether multiplexing is feasible, allowing adaptive adjustment of processing timelines to balance efficiency and versatility requirements
Solution Approach 2:
The patent changes the timing parameter values based on the multiplexing decision. When relaxed timing conditions are applied, the processing time parameters are extended compared to baseline conditions. This parameter adjustment allows the system to accommodate multiplexing operations while maintaining efficient processing when multiplexing is not required
2Loss of energy
If multiple types of information are multiplexed in a single uplink transmission, then resource efficiency is improved, but processing time requirements increase
Solution Approach 1:
The patent applies preliminary action by evaluating the feasibility of multiplexing and determining the appropriate timing conditions before the actual UCI processing begins. The UE assesses whether relaxed timing conditions can be applied based on current resource allocations and processing capabilities, allowing sufficient time to be allocated in advance for multiplexing operations if needed
Solution Approach 2:
The system dynamically adjusts processing time allocation based on the multiplexing decision. When multiple information types are multiplexed, the relaxed timing conditions provide extended processing time. When single-type transmission occurs, baseline timing conditions apply for faster processing, thus optimizing the trade-off between resource efficiency and processing time
3Adaptability or versatility
If relaxed timing conditions are applied to accommodate multiplexing, then multiplexing capability is improved, but processing time increases
Solution Approach 1:
The patent implements parameter changes by switching between different timing condition sets. The first set of timing parameters is specifically designed with relaxed requirements to accommodate multiplexing operations, while the second set provides tighter timing for standard operations. The system selects the appropriate parameter set based on the transmission scenario
