PDCCH Transport Block Scheduling via Transmission Interval Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems using Machine Type Communication (MTC) and Narrow Band Internet of Things (NB-IoT, the continuous scheduling of transport blocks on physical downlink control channels (PDCCH) occupies resources for extended periods, hindering the scheduling of other terminals and reducing timeliness.
Innovation Solution
Implementing a method to determine transmission interval parameters for scheduling transport blocks on PDCCH, allowing for the setting of transmission intervals among transport blocks, which releases physical resources for other terminals to use, thereby reducing the impact of continuous scheduling on other terminals and improving timeliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transport blocks are continuously scheduled on PDCCH, then the scheduling reliability is improved, but the resource occupation time increases and timeliness deteriorates
Solution Approach 1:
The patent implements periodic transmission of transport blocks with configured intervals rather than continuous transmission. The network device determines transmission interval parameters and schedules transport blocks periodically, allowing other terminals to access resources during interval periods while maintaining reliable communication through repeated transmissions at scheduled intervals.
2Reliability
If transport blocks are continuously scheduled on PDCCH, then the transmission reliability is improved, but the scheduling timeliness for other terminals deteriorates
Solution Approach 1:
The system uses periodic transmission with configured intervals to allow other terminals to schedule during released resource intervals. This maintains transmission reliability through repeated transport block transmissions while improving scheduling timeliness by freeing resources periodically for other users.
Solution Approach 2:
The patent dynamically adjusts transmission interval parameters based on channel conditions and traffic requirements. The network device can configure different interval values to balance reliability requirements against scheduling timeliness needs, making the system adaptable to different operational scenarios.
3Productivity
If transmission intervals are set among transport blocks, then the resource utilization efficiency is improved, but the scheduling complexity increases
Solution Approach 1:
The patent manages scheduling complexity by parameterizing transmission intervals through configuration messages from the network device. Instead of complex real-time decisions, the system uses pre-configured interval parameters that simplify the scheduling logic while maintaining high resource utilization efficiency through periodic release of time-frequency resources.
