SSB Measurement Report via Msg3 for TCI State Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In new generation communication systems, the delay in configuring Transmission Configuration Indication (TCI) states for terminals due to beam measurement and reporting processes hinders timely selection of suitable receiving beams, affecting throughput.
Innovation Solution
A method where the terminal receives configuration information for SSB measurement from the base station, performs the measurement, and sends the report through a designated message, allowing the base station to configure TCI states efficiently, thereby reducing delay and improving throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the base station waits for the complete beam measurement and reporting process before configuring TCI states, then the beam measurement accuracy is improved, but the time delay for TCI configuration increases
Solution Approach 1:
The terminal performs SSB measurement and sends the measurement report in advance through the first designated message (Msg3) during the random access procedure, before the traditional beam measurement configuration process. This preliminary action allows the base station to obtain measurement results earlier and configure TCI states without waiting for the complete traditional beam measurement process, thus reducing configuration delay while maintaining measurement accuracy.
2Loss of time
If the terminal sends the SSB measurement report through the first designated message, then the TCI configuration time is reduced, but the message complexity increases
Solution Approach 1:
The SSB measurement report is merged with the first designated message (Msg3) that is already used for contention resolution during the random access procedure. By combining the measurement report with an existing message rather than creating a separate dedicated message, the patent reduces overall system complexity while achieving faster TCI configuration. The terminal adds the measurement report to Msg3, and the base station extracts it during the existing random access processing.
3Reliability
If the base station configures TCI states after random access completion through traditional beam measurement process, then the measurement process is thorough, but the throughput is affected due to delay
Solution Approach 1:
The terminal performs SSB measurement and sends the measurement report in advance through the first designated message (Msg3) during the random access procedure, before the traditional beam measurement configuration process. This preliminary action allows the base station to obtain measurement results earlier and configure TCI states without waiting for the complete traditional beam measurement process, thus reducing configuration delay while maintaining measurement accuracy.

AI summary
The present disclosure provides a transmission configuration method and device. The method is applied to a terminal, and comprises: receiving SSB measurement configuration information sent by a base station; carrying out SSB measurement according to the SSB measurement configuration information to obtain an SSB measurement report; and sending the SSB measurement report to the base station by means of a first designated message, wherein the first designated message is a message for representing contention resolution in a random access process, so that the base station configures a TCI state set for the terminal according to the SSB measurement report. Therefore, the present disclosure can improve the efficiency of transmission configuration and reduce a time delay.
