SSB Transmission Pattern Configuration for Wireless Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, User Equipment (UE) faces challenges in detecting and measuring Synchronization Signal (SS) blocks and beams from neighboring cells due to unclear transmission patterns, leading to inefficient resource usage and increased complexity, especially at high frequency ranges where many SS blocks need to be scanned, resulting in missed detections and wasted resources.
Innovation Solution
A method where network nodes provide configuration patterns indicating which SS blocks or beams are actually transmitted by neighboring nodes, allowing UE to focus measurements on active signals, reducing unnecessary scans and improving detection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE scans all possible SS blocks to ensure detection, then detection coverage is improved, but resource consumption and measurement time increase significantly
Solution Approach 1:
The network node provides preliminary information about the actual transmission pattern of SS blocks before UE performs measurements. This allows UE to pre-know which SS blocks will be transmitted and focus measurements only on those blocks, eliminating the need to scan all possible blocks and significantly reducing measurement time while maintaining detection coverage
Solution Approach 2:
The invention extracts only the relevant SS block transmission information from the complete set of possible SS blocks and provides it to UE. Instead of UE processing all possible SS block positions, the network extracts and communicates only the actual transmission pattern, reducing the measurement scope to essential elements only

3Measurement precision
If UE increases scanning complexity to detect SS blocks from multiple neighboring cells, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The network node acts as an intermediary that provides transmission pattern information to UE. Instead of UE independently determining which SS blocks are transmitted by multiple neighboring cells (which would require complex analysis), the network intermediary directly provides the transmission pattern information, simplifying UE's detection process while maintaining or improving detection accuracy through more reliable information

AI summary
Embodiments include methods performed by a second network node in a wireless communications network that includes a first network node, the second network node, and a third network node. Such methods include receiving, from the first network node, a configuration comprising a pattern indicative of whether or not each of a plurality of Synchronization Signal Block (SSB) transmissions, that are configured based on a nominal timing, are actually transmitted by the third network node according to the nominal timing. Such methods include, based on the received configuration, managing transmission and/or reception configurations for one or more of the following: one or more cells served by the second network node; and one or more UEs served by the second network node via the one or more cells. Other embodiments include second network nodes configured to perform such methods.
