Terminal Device SSB Detection Timing Sequence Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-beam communication systems, terminal devices face high calculation complexity and power consumption during synchronization signal block (SSB) detection due to the need to perform detection across multiple beams within a whole SS cycle, leading to prolonged detection times.
Innovation Solution
The method involves determining and utilizing timing sequences for multiple SSBs in advance, allowing terminal devices to receive SSBs on fixed time-domain resources, thereby reducing calculation complexity and power consumption. This is achieved through indication information from network devices, which configures the timing sequences based on the number and type of SSBs, using protocols like RRC signaling or broadcast messages.

1Reliability
If terminal device performs detection in whole SS cycle to obtain multi-beam condition, then detection completeness is improved, but detection time increases and power consumption increases
Solution Approach 1:
The network device performs preliminary action by determining and notifying the terminal device of the timing sequence for multiple SSBs in advance. The terminal device receives indication information containing timing sequence information before actual SSB detection, allowing it to prepare detection resources and perform detection only at predetermined time points rather than scanning the entire SS cycle, thus reducing detection time while maintaining detection completeness
Solution Approach 2:
The system implements dynamic adaptation by allowing the network device to flexibly configure and notify different timing sequences for multiple SSBs based on actual network conditions. The terminal device dynamically adjusts its detection strategy according to the received timing sequence information, optimizing detection performance while reducing power consumption and detection time
