Synchronization Signal Block Configurations for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications, the use of fixed frequency resources for transmitting synchronization signals can result in inconsistent reception quality among user equipment (UEs) due to varying receiver characteristics, limiting their ability to connect with or synchronize communications with network entities.
Innovation Solution
A network entity transmits synchronization signals using dynamic time-frequency patterns, which include varying frequency resources, carrier frequencies, and periodicities, allowing UEs to effectively receive and decode synchronization signals by creating frequency-diversified transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed frequency resources are used for transmitting synchronization signals, then transmission simplicity is maintained, but reception quality consistency deteriorates due to varying receiver characteristics
Solution Approach 1:
The patent applies dynamics by transitioning from fixed frequency resources to dynamic time-frequency patterns. The network entity transmits synchronization signals using multiple time-frequency patterns that vary in carrier frequency and periodicity, allowing the system to adapt to different receiver characteristics and improve reception quality consistency while maintaining manageable transmission complexity through structured pattern design
2Reliability
If multiple time-frequency patterns are used for synchronization signals, then reception quality and detection probability improve, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing synchronization signal transmission into multiple distinct time-frequency patterns, each with specific carrier frequencies and periodicities. This segmentation allows different UEs to monitor for specific patterns based on their receiver characteristics, improving reception quality while managing complexity through organized pattern categorization rather than completely random transmission
Solution Approach 2:
The patent applies parameter changes by varying carrier frequency and periodicity parameters across different time-frequency patterns. The network entity changes these parameters to create diverse transmission patterns that can be detected by different UE receivers, improving detection probability and reception quality while maintaining systematic control over the parameter variations
3Adaptability or versatility
If UEs monitor for multiple time-frequency patterns, then connection establishment capability improves, but monitoring complexity and processing load increase
Solution Approach 1:
The patent applies dynamics to UE monitoring by enabling UEs to dynamically select and monitor for specific time-frequency patterns based on their receiver characteristics and connection requirements. This dynamic monitoring approach improves connection establishment capability for diverse UE types while managing processing load by allowing UEs to focus on relevant patterns rather than processing all possible patterns uniformly

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for a set of synchronization signals that includes a first subset of synchronization signals allocated according to a first time-frequency pattern and a second subset of synchronization signals allocated according to a second time-frequency pattern different than the first time-frequency pattern. The first subset of synchronization signals and the second subset of synchronization signals are monitored during a first time interval. The UE may receive one or more synchronization signals of the set of synchronization signals based on the monitoring. The UE may establish a connection with a network entity based on receiving the one or more synchronization signals. The UE may receive an indication of the second time-frequency pattern from one or more synchronization signals of the first subset of synchronization signals.
