SCG Activation Recording for Lower Latency and Fewer Failures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-connectivity scenarios, the activation of a Secondary Cell Group (SCG) for data transmission is often inefficient due to inadequate recording of Random Access (RA) related information during the SCG activation procedure, leading to suboptimal network adjustments and increased failure probability.
Innovation Solution
An information processing method that records and reports SCG activation success/failure procedures to the network, including details like RACH resource usage, RACH-less activation status, and timing information, enabling network-side optimization of SCG activation configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional statistical recording method for RA related information is adopted, then the recording process is simple, but the RA related information and auxiliary information in SCG activation procedure cannot be recorded or accurately recorded
Solution Approach 1:
The patent segments the recording process by creating a dedicated statistical recording structure that separates SCG activation-related information from other Random Access information. This is achieved by introducing specific event identifiers (e.g., eventID indicating SCG activation) and structured data fields that isolate and specifically track activation procedure information, thereby improving recording accuracy without overwhelming complexity
Solution Approach 2:
The patent introduces an intermediary statistical recording mechanism that acts as a bridge between the SCG activation procedure and the network side. This intermediary structure collects and organizes RA related information during activation, including success/failure status and auxiliary information, before presenting it to the network for optimization purposes
2Productivity
If SCG is activated in deactivated state, then power-saving is achieved and rapid activation is enabled, but statistical recording of RA related information is adversely affected
Solution Approach 1:
The patent applies preliminary action by pre-configuring the statistical recording structure and event identification mechanisms before SCG activation occurs. The UE is prepared to recognize and record activation-related RA information through pre-established measurement and reporting frameworks, ensuring no information is lost during the rapid activation process
Solution Approach 2:
The patent implements feedback mechanisms where the UE records and reports RA related information back to the network side after SCG activation. This feedback loop includes success/failure status and auxiliary information, allowing the network to receive comprehensive data about the activation procedure despite the rapid timescale and power-saving constraints

AI summary
This application provides an information processing method, an information processing apparatus, a device and a computer readable storage medium, which relates to the technical field of communications. The information processing method includes: receiving an SCG activation command from a network side; and activating an SCG according to the SCG activation command, and recording information related to the SCG activation procedure. In this application, when activation of the SCG is performed according to the SCG activation command from the network side, a UE records the information related to the SCG activation procedure, and reports it to the network side, which assists optimization of SCG activation procedure for the network side, reduces SCG activation latency, and reduces probability of SCG activation failure.
