Asynchronous SSB SMTC Configuration via Indication Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for configuring Synchronization Signal/Physical Broadcast Channel (SS/PBCH) Block (SSB) measurement timing configuration (SMTC) do not effectively handle asynchronous SSBs, as their configurations are not carried in system broadcast messages, leading to difficulties in determining the correct SMTC for frequency layers where asynchronous SSBs are located.
Innovation Solution
A method and apparatus that receive first configuration information to determine a measurement frequency list configuration, including measurement configurations for frequency layers corresponding to asynchronous SSBs, which carry indication information to determine the SMTC configuration for performing measurements at the frequency layer where the asynchronous SSB is located, allowing for efficient SMTC configuration even when not explicitly provided in system broadcast messages.

Engineering Contradiction Analysis
1Ease of manufacture
If SMTC configuration is carried in system broadcast message for synchronous SSB, then measurement configuration is simplified and efficient, but SMTC configuration for asynchronous SSB cannot be provided
Solution Approach 1:
The patent introduces a measurement frequency list configuration as an intermediary mechanism that carries indication information for asynchronous SSB SMTC configuration. This intermediary structure enables the transmission of asynchronous SSB measurement timing information without modifying the existing system broadcast message format for synchronous SSB, thus maintaining backward compatibility while extending support to asynchronous scenarios.
Solution Approach 2:
The patent segments the measurement configuration into two parts: SMTC configuration carried in system broadcast messages for synchronous SSB, and measurement frequency list configuration with indication information for asynchronous SSB. This segmentation allows each configuration type to be handled independently through appropriate channels, resolving the contradiction between simplified configuration and extended adaptability.
2Measurement precision
If SMTC configuration is explicitly provided in system broadcast message, then measurement accuracy is improved, but information overhead increases for multiple frequency layers
Solution Approach 1:
The patent uses indication information in the measurement frequency list configuration to copy or reference the SMTC configuration for asynchronous SSB from existing configurations. Instead of transmitting complete SMTC configuration data for each asynchronous frequency layer, the indication information points to or copies necessary parameters, reducing information overhead while maintaining measurement precision.
Solution Approach 2:
The measurement frequency list configuration serves multiple functions: it provides measurement frequency information and simultaneously carries indication information for SMTC configuration of asynchronous SSB. This multi-functionality reduces the need for separate dedicated configuration messages, thereby reducing overall information overhead while ensuring accurate measurement configuration.
3Measurement precision
If separate configuration is provided for each frequency layer, then measurement accuracy for asynchronous SSB is improved, but device complexity increases
Solution Approach 1:
The patent merges the measurement frequency list configuration with the SMTC indication information into a single configuration structure. By combining frequency layer information and SMTC configuration indication in one place, the patent reduces the number of separate configuration messages and simplifies the overall configuration management process while maintaining accurate measurement configuration for each asynchronous frequency layer.
Data Source
AI summary
A method for information configuration includes that: a terminal receives first configuration information, where the first configuration information is used for determining a measurement frequency list configuration, the measurement frequency list configuration includes measurement configuration of at least one first frequency layer corresponding to an asynchronous synchronization signal/physical broadcast channel block (SSB); and where the measurement configuration of the at least one first frequency layer carries first indication information, the first indication information is used by the terminal to determine a SSB measurement timing configuration (SMTC) configuration used for performing measurement at a frequency layer where the asynchronous SSB is located. The terminal and a non-transitory computer-readable storage medium are also provided.
