Wireless Slot Symbol Conflict Resolution for Clear UE Behavior
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Future wireless communications networks face challenges in efficiently handling diverse terminal devices with varying data traffic profiles due to conflicting configurations of uplink and downlink symbols in slot structures, leading to ambiguous UE behavior.
Innovation Solution
A method for a communications device to autonomously determine symbol configurations using a conflict resolution rule based on dynamic characteristics of multiple slot configuration methods, prioritizing more dynamic indicators like UE-specific DCI to resolve conflicts and treat ambiguous symbols as 'Unknown' or 'Reserved', ensuring flexible symbol usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple slot configuration methods are used to support diverse terminal devices with different data traffic profiles, then network flexibility and adaptability are improved, but symbol configuration conflicts arise leading to ambiguous UE behavior
Solution Approach 1:
The patent applies parameter changes by introducing a dynamic characteristic parameter (rate of change of slot configuration information) to differentiate between various slot configuration methods. This allows the system to prioritize configurations based on their dynamic characteristics, resolving conflicts by selecting the configuration with the appropriate rate of change for the given scenario, thus maintaining both network flexibility and UE behavior clarity
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a conflict resolution rule that acts as a mediator between multiple slot configuration methods. This intermediary layer processes conflicting configurations by evaluating their dynamic characteristics and applying predetermined rules to determine the final symbol configuration, eliminating ambiguity while preserving the adaptability of multiple configuration methods
2Productivity
If dynamic slot configuration information is used to efficiently handle varying data traffic profiles, then communication efficiency is improved, but configuration conflicts increase leading to ambiguity
Solution Approach 1:
The patent applies preliminary action by establishing predetermined conflict resolution rules before configuration conflicts occur. These rules are configured in advance based on the dynamic characteristics of different slot configuration methods, allowing the UE to autonomously resolve conflicts without additional signaling, thus maintaining communication efficiency while preventing configuration clarity loss
Solution Approach 2:
The patent implements a feedback mechanism where the UE autonomously determines the final symbol configuration by evaluating the dynamic characteristics of received slot configuration information against predetermined rules. This feedback loop ensures that the UE behavior remains clear and unambiguous while still allowing dynamic adaptation to varying traffic profiles, as the resolution process provides deterministic outcomes

AI summary
A method comprises receiving from an infrastructure equipment of wireless communications network slot configuration information indicating a configuration of one or more slots of a wireless access interface provided by a wireless communications network for communicating data to the communications device in the downlink and receiving data from the communications device in the uplink, the time divided slots of the wireless access interface each providing a plurality of symbols on one of more radio frequency carrier signals which can be configured differently for use by the communications device or the infrastructure equipment, the slot configuration information including an indication that one or more of the plurality of symbols are to be used for transmitting signals from the communications device or that one or more of the plurality of symbols are to be used for receiving signals at the communications device.
