Fast Measurement Reporting for Wireless Connection Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless systems face significant delays and suboptimal measurement results due to lengthy measurement times and changing channel conditions, particularly in frequency range 2 (FR2), leading to stale measurements and reduced system capacity and throughput.
Innovation Solution
Implementing fast measurement reporting by configuring user equipment (UE) to initiate measurements on designated carriers during connection setup, allowing for concurrent measurement and connection setup processes, thereby reducing measurement time and ensuring current measurement results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If measurements are performed in idle mode before connection setup, then measurement results are available for connection setup decisions, but the measurement results become stale due to lengthy measurement time and channel condition changes
Solution Approach 1:
The UE is pre-configured with measurement configurations and parameters while in idle mode, including fast measurement reporting carrier frequencies and other measurement parameters. When a connection setup trigger occurs, the UE immediately initiates measurements on the configured fast measurement reporting carriers without waiting for connection establishment, thereby performing preliminary measurement actions that reduce overall measurement time while maintaining result accuracy through concurrent execution with connection setup procedures
2Measurement precision
If measurements are performed after connection establishment, then current channel conditions can be measured, but significant time is wasted on connection setup and measurement initiation
Solution Approach 1:
Measurement configurations are prepared and stored in advance during idle mode, including carrier frequencies, measurement parameters, and reporting configurations. When connection setup is triggered, the UE immediately starts measurements on pre-configured fast measurement reporting carriers rather than waiting for connection establishment, thereby performing preliminary measurement actions that eliminate setup delay while ensuring measurements reflect current channel conditions
Solution Approach 2:
The measurement process continues concurrently with the connection setup procedure rather than being sequential. The UE performs measurements on fast measurement reporting carriers during the connection setup process, maintaining continuous useful action (measurement) throughout the transition from idle to connected mode, thereby eliminating idle time and ensuring current channel condition data is available immediately upon connection establishment
3Measurement precision
If traditional measurement procedures are used with sequential carrier measurement, then comprehensive measurement coverage is achieved, but total measurement time becomes prohibitive
Solution Approach 1:
The UE is pre-configured with multiple carrier frequencies and measurement parameters for fast measurement reporting before connection setup. When measurement trigger occurs, the UE immediately initiates parallel measurements on all configured fast measurement reporting carriers using pre-prepared measurement configurations, thereby performing preliminary measurement actions that enable comprehensive carrier coverage measurement to occur concurrently rather than sequentially, dramatically reducing total measurement time while maintaining complete measurement coverage
