Terminal Switching Time Reporting for Flexible Data Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current switching time capabilities in Dual-Connectivity from Evolved Universal Terrestrial Radio Access (E-UTRA) to New Radio (NR) and vice versa do not cover all scenarios, leading to ineffective data scheduling and lost opportunities for opportunistic transmission due to inflexible time domain positions and long switching times.
Innovation Solution
A data processing method that allows terminal devices to report switching time capabilities to network devices, enabling flexible scheduling based on switching times from one network to another, including the option to transmit or not transmit data within specified switching times, thereby improving scheduling efficiency and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If Type1 or Type2 switching time capabilities are used, then switching time is reduced to less than 0.5 μs or 20 μs respectively, but all scenarios cannot be covered and effective scheduling cannot be implemented
Solution Approach 1:
The patent introduces dynamic switching time capability reporting, where the terminal device determines and reports its switching time capability based on current network conditions and terminal states. This allows the system to adapt switching time requirements dynamically rather than being constrained to fixed Type1 or Type2 categories, enabling effective scheduling across diverse scenarios while maintaining appropriate switching time performance.
Solution Approach 2:
The patent changes the parameter representation from fixed categories (Type1/Type2) to flexible numerical values. The terminal device reports specific switching time capability values that can vary continuously, allowing the network device to schedule based on actual capability rather than predefined categories. This parameter change enables both time optimization and scenario adaptability.
2Ease of operation
If fixed switching time capabilities are enforced, then scheduling simplicity is maintained, but opportunistic transmission opportunities are lost due to inflexible time domain positions
Solution Approach 1:
The patent enables dynamic adjustment of time domain positions based on reported switching time capabilities. The network device can flexibly schedule data transmissions within the switching time window rather than being constrained to fixed positions, thereby capturing opportunistic transmission opportunities while maintaining scheduling manageability through capability-based constraints.
Solution Approach 2:
The terminal device performs preliminary action by reporting its switching time capability before data scheduling occurs. This advance information allows the network device to plan and optimize scheduling decisions, balancing simplicity with opportunistic transmission by knowing the available time window in advance.
