Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in synchronization signal block (SSB) transmission, leading to resource waste and increased power consumption, particularly in low-traffic scenarios, and unreliable SSB detection methods result in synchronization losses and increased latency.
Innovation Solution
Implementing a method for user equipment (UE) to selectively generate SSB measurement metrics based on indicated SSB transmission types, including continuously active, on-demand, and adaptive types, using reduced signaling and dynamic configuration to enhance detection reliability and reduce resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SSB transmission is continuously active to ensure reliable synchronization, then synchronization reliability is improved, but resource consumption and power usage increase
Solution Approach 1:
The patent implements dynamic SSB transmission where the network node adapts transmission behavior based on UE presence detection and traffic conditions. The system transitions between continuous transmission mode (when UEs are present) and discontinuous transmission mode (when no UEs are detected), allowing synchronization reliability to be maintained only when needed, thereby reducing unnecessary power consumption during idle periods.
Solution Approach 2:
The patent changes the transmission parameter state from static continuous transmission to dynamic variable transmission. By monitoring UE presence and adjusting transmission parameters (transmission on/off states, periodicity), the system optimizes the balance between synchronization reliability and power consumption based on actual network conditions rather than maintaining fixed continuous transmission.
2Loss of energy
If SSB transmission is reduced to save resources in low-traffic scenarios, then resource consumption decreases, but synchronization detection reliability deteriorates
Solution Approach 1:
The patent performs preliminary UE presence detection and traffic condition assessment before adjusting SSB transmission. By proactively identifying when UEs are absent or traffic is minimal, the system can safely reduce or suspend SSB transmission without risking synchronization detection reliability, as the absence of UEs indicates no synchronization is currently needed.
Solution Approach 2:
The patent implements feedback mechanisms where the network node continuously monitors UE presence, traffic conditions, and synchronization status. This feedback loop enables the system to dynamically adjust SSB transmission levels, ensuring that transmission is reduced only when conditions indicate it is safe to do so, thereby maintaining detection reliability while optimizing resource consumption.
3Ease of operation
If traditional SSB detection methods are used, then detection simplicity is maintained, but latency increases and synchronization losses occur
Solution Approach 1:
The patent segments the SSB transmission and detection process into distinct phases: UE presence detection phase, traffic condition assessment phase, and SSB transmission/detection phase. This segmentation allows the system to perform preliminary checks before full SSB transmission, reducing unnecessary transmission latency while maintaining detection simplicity for actual synchronization events.
Solution Approach 2:
The patent performs preliminary actions (UE presence detection, traffic condition assessment) before initiating SSB transmission. This preliminary preparation reduces latency by ensuring SSB transmission only occurs when UEs are actually present and synchronization is needed, eliminating wasted time from unnecessary transmissions while keeping the detection process itself simple.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) transmission type indication that is associated with an SSB transmission capability of a network node, the SSB transmission type indication being one of multiple SSB transmission type options that include: a continuously active SSB transmission type, an on-demand (OD)-SSB transmission type, and an adaptive SSB transmission type that is a combination of the continuously active SSB transmission type and the OD-SSB transmission type. The UE may generate an SSB measurement metric selectively and based at least in part on the SSB transmission type indication. Numerous other aspects are described.
