Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in differentiating between synchronization signal block (SSB) transmission in licensed and unlicensed operating modes, leading to inefficient resource usage, increased latency, and communication errors due to improper interpretation of SSB contents.
Innovation Solution
A method and apparatus for determining the operating mode associated with SSB transmission, allowing user equipment (UE) and base stations to differentiate between licensed and unlicensed modes by identifying specific characteristics such as candidate SSB positions, PBCH content, and synchronization rasters, enabling appropriate resource allocation and accurate content interpretation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SSB transmission is performed without differentiating between licensed and unlicensed operating modes, then resource allocation and content interpretation may be incorrect, but the system complexity increases and communication errors occur
Solution Approach 1:
The patent applies preliminary action by determining the operating mode (licensed or unlicensed) before performing SSB transmission or reception. The base station determines the operating mode associated with SSB transmission in a band, and the UE determines the operating mode before receiving SSBs. This preliminary determination ensures that subsequent resource allocation and content interpretation are performed correctly for the specific operating mode, preventing communication errors while maintaining clear procedural separation.
2Productivity
If SSB transmission uses fixed resource allocation without operating mode differentiation, then device complexity is reduced, but resource usage efficiency decreases and latency increases
Solution Approach 1:
The patent applies dynamics by making the SSB transmission parameters dynamic based on the determined operating mode. Instead of fixed resource allocation, the base station allocates candidate SSB positions, PBCH content, and synchronization rasters dynamically according to whether the operating mode is licensed or unlicensed. This dynamic adaptation optimizes resource usage efficiency and reduces latency for each specific operating mode while maintaining manageable device complexity through mode-based parameter selection.
3Productivity
If SSB transmission parameters are adapted to specific operating modes, then communication efficiency improves, but the complexity of determining and managing different parameters increases
Solution Approach 1:
The patent applies segmentation by dividing the SSB transmission parameters into distinct segments based on operating mode. The base station determines the operating mode and selects from pre-defined sets of parameters appropriate for that mode (licensed or unlicensed). The UE similarly determines the operating mode and uses the corresponding parameter set for reception. This segmentation allows communication efficiency to improve through mode-optimized parameters while keeping device complexity manageable by organizing parameters into separate, mode-specific groups rather than requiring complex real-time adaptation.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an operating mode associated with synchronization signal block (SSB) transmission in a band, wherein the operating mode is one of a licensed operating mode or an unlicensed operating mode; and receive one or more SSBs based at least in part on the operating mode. Numerous other aspects are described.
