Engineering Contradiction Analysis
1Use of energy by moving object
If dynamic adaptation of SSB resources is implemented, then energy efficiency is improved, but ambiguity in UE behavior increases
Solution Approach 1:
The patent introduces feedback mechanisms where the network entity provides explicit indications to the UE about SSB transmission status and collision resolution rules. This feedback loop eliminates ambiguity by having the network directly communicate its intentions regarding SSB adaptation and uplink transmission priorities, allowing the UE to make informed decisions about handling collisions between dynamically adapted SSBs and scheduled uplink transmissions.
Solution Approach 2:
The patent applies preliminary action by having the network entity configure and indicate SSB transmission parameters in advance before actual collisions occur. The UE receives configuration information about SSB resources and collision resolution rules beforehand, enabling it to prepare appropriate responses and actions before the actual transmission collision happens, thus reducing operational ambiguity.
2Productivity
If SSB transmission resources are dynamically adapted, then spectral efficiency is improved, but uplink transmission reliability decreases
Solution Approach 1:
The patent implements dynamics by allowing the network entity to dynamically adjust SSB transmission resources based on current system conditions, traffic patterns, and collision scenarios. The SSB resources can be adapted in real-time through dynamic indications, enabling the system to optimize spectral efficiency while maintaining uplink transmission reliability through flexible resource allocation and collision resolution mechanisms.
Solution Approach 2:
The patent applies parameter changes by modifying SSB transmission parameters such as timing, frequency resources, and transmission periodicity based on network conditions. These parameter adjustments allow the system to optimize spectral efficiency while ensuring that uplink transmissions are not unduly affected, as the parameter changes are made dynamically and with appropriate collision resolution rules in place.
3Ease of operation
If clear collision resolution rules are implemented, then UE behavior is clarified, but system flexibility is reduced
Solution Approach 1:
The patent applies segmentation by dividing the collision resolution process into distinct, manageable rules and scenarios. Instead of providing a single complex decision framework, the system segments collision resolution into specific cases (e.g., different types of uplink transmissions, different SSB configurations) with predetermined handling rules for each segment, making UE behavior clearer while maintaining overall system flexibility through scenario-specific approaches.

AI summary
Certain aspects of the present disclosure provide techniques for resolving uplink collision with dynamically adapted synchronization signal blocks (SSBs). An example method, performed at a user equipment (UE), generally includes receiving first signaling configuring the UE with resources for synchronization signal block (SSB) reception, receiving second signaling dynamically adapting the resources for SSB reception, and processing at least one scheduled uplink transmission based on the second signaling.
