PUCCH Deferral Order Management for Uplink Transmission Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack a mechanism to manage the sequential order of deferral procedures and slot index-dependent procedures, leading to inefficiencies in uplink transmission management, particularly for physical uplink control channel (PUCCH) repetitions, due to the lack of a clear method to determine whether to use the original or deferred slot index for slot index-dependent processes.
Innovation Solution
A method is introduced to determine a sequential order for performing deferral procedures and slot index-dependent procedures, allowing the UE to defer PUCCH repetitions and adjust slot index-dependent processes accordingly, ensuring that these procedures are executed in a coordinated manner, thereby enabling the system to manage the sequential order effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a deferral procedure is performed on PUCCH repetitions, then transmission reliability is improved by avoiding downlink symbols, but the slot index for slot index-dependent procedures becomes ambiguous leading to management inefficiency
Solution Approach 1:
The patent applies preliminary action by determining the sequential order of procedures before executing them. The network entity or UE determines whether to perform the deferral procedure first or the slot index-dependent procedure first, based on pre-established rules. This preliminary determination of execution order eliminates the ambiguity of slot index usage and ensures efficient management of uplink transmissions while maintaining transmission reliability through deferral when needed.
2Speed
If the original slot index is used for slot index-dependent procedures, then processing speed is improved, but transmission reliability deteriorates due to potential conflicts with downlink symbols
Solution Approach 1:
The patent applies dynamics by making the procedure execution order flexible and adaptive rather than fixed. The system can dynamically determine whether to execute the deferral procedure first or the slot index-dependent procedure first, based on the specific transmission scenario. This dynamic approach allows the system to prioritize processing speed when the original slot is safe, while ensuring transmission reliability by deferring when downlink symbol conflicts are detected.
3Reliability
If the deferred slot index is used for slot index-dependent procedures, then transmission reliability is improved by avoiding downlink symbol conflicts, but processing speed deteriorates due to additional deferral overhead
Solution Approach 1:
The patent applies self-service by enabling the UE to autonomously determine the execution order of procedures based on pre-configured rules received from the network. The UE independently evaluates whether to perform deferral first or the slot index-dependent procedure first, without requiring additional network intervention for each decision. This self-service mechanism reduces processing overhead and speeds up transmissions while maintaining reliability, as the UE can make rapid decisions based on the established sequential order rules.

AI summary
This disclosure provides systems, methods, and devices for wireless communication that provide a mechanism for managing a sequential order for performing a deferral procedure and at least one other slot index-dependent procedure in a wireless communication system. In particular aspects, a user equipment, UE, may be configured to perform a first slot index-dependent procedure and a deferral procedure of uplink repetitions. The UE may determine a sequential order for performing the deferral procedure and the first slot index-dependent procedure, and may then perform the deferral procedure and the first slot index-dependent procedure in the sequential order. The sequential order may include performing the deferral procedure before the first slot index-dependent procedure, performing the deferral procedure after the first slot index-dependent procedure, or a sequential order that is based on a type of procedure of the first slot index-dependent procedure.
