SMTC Reporting for Low-Power SS/PBCH Block Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication systems, terminals consume excessive power during the process of reading synchronization signal/physical broadcast channel (SS/PBCH) blocks through blind detection during reselection, connection establishment, or connection recovery.
Innovation Solution
Terminals and network-side devices implement a method where terminals report and network-side devices receive synchronization broadcast signal block measurement timing configuration (SMTC) configuration information, allowing terminals to store and share this information to avoid repeated blind detection, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal reads the SS/PBCH block through blind detection, then the terminal can obtain synchronization information, but the power consumption of the terminal increases
Solution Approach 1:
The network side performs preliminary actions by determining SS/PBCH block resources and generating indication information before the terminal needs to access them. This allows the terminal to receive pre-configured resource information through downlink signaling, avoiding the need for blind detection and reducing power consumption while ensuring reliable synchronization information acquisition
2Productivity
If the terminal performs blind detection to read SS/PBCH blocks during connection establishment or reselection, then the terminal can establish or recover connection, but the detection process becomes complex and time-consuming
Solution Approach 1:
The network side provides feedback by sending indication information that explicitly tells the terminal where SS/PBCH blocks are located and how to read them. This feedback mechanism eliminates the trial-and-error nature of blind detection, reducing both the time required for connection establishment and the computational complexity of the detection process
