Engineering Contradiction Analysis
1Use of energy by stationary object
If periodic SSB configurations are used, then coverage measurement and beam management are maintained, but energy consumption increases and adaptation speed decreases
Solution Approach 1:
The patent implements dynamic SSB configuration where the network entity can activate or deactivate SSB transmissions based on current network conditions and UE requirements. This transforms the static periodic SSB transmission into a dynamic process that adapts to changing conditions, reducing energy consumption when SSBs are deactivated while maintaining fast adaptation capability when activated.
Solution Approach 2:
The patent changes the transmission parameters of SSBs from fixed periodic intervals to variable timing based on measurement timing configurations. The network entity can adjust the timing and frequency of SSB transmissions according to UE measurement requirements, enabling energy savings through reduced transmission frequency while maintaining measurement accuracy when needed.
2Loss of energy
If dynamic time-adapted SSB configurations are implemented, then energy efficiency improves, but measurement configuration complexity increases
Solution Approach 1:
The patent introduces measurement timing configuration as an intermediary layer between the network entity and UE. This configuration structure standardizes the dynamic SSB transmission parameters and timing, simplifying the complexity by providing a predefined framework that both network entity and UE can follow, rather than requiring complex ad-hoc negotiations for each dynamic SSB transmission.
Solution Approach 2:
The patent establishes measurement timing configurations in advance that define potential SSB transmission opportunities and parameters. This preliminary configuration allows the network entity to quickly activate or deactivate SSBs within the pre-defined framework without requiring complex real-time configuration negotiations, thus improving energy efficiency while managing complexity through advance planning.
3Productivity
If on-demand SSB transmissions are used, then network resource utilization improves, but synchronization and measurement reliability may decrease
Solution Approach 1:
The patent combines on-demand SSB transmissions with periodic measurement timing configurations. While individual SSB transmissions may be activated or deactivated based on demand, the measurement timing configuration maintains a periodic structure that ensures UEs can reliably synchronize and perform measurements whenever SSBs are transmitted, thus maintaining synchronization reliability while improving resource utilization through selective activation.

AI summary
Methods, systems, and devices for wireless communications are described. A wireless communications system may support a measurement configuration for on-demand synchronization signal block (SSB) and time-domain SSB adaptation. A user equipment (UE) of the wireless communications system may receive, from a first network entity associated with a serving cell of the UE, one or more first control messages including a measurement timing configuration indicating a first set of multiple SSBs to be received by the UE from a neighbor cell via a first frequency layer. The measurement timing configuration may be associated with a capability of the neighbor cell to dynamically time-adapt the first set of multiple SSBs. The UE may monitor for the first set of multiple SSBs in accordance with the measurement timing configuration.
