Terminal Scheduling for Overlapping UL/DL Resource Periods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In future radio communication systems, the lack of uplink resources compared to downlink resources leads to decreased throughput and system performance deterioration due to insufficient study on methods to increase uplink resources.
Innovation Solution
A terminal and base station are designed to control the transmission and reception of uplink and downlink channels by configuring overlapping periods in the time domain, allowing simultaneous transmission and reception of uplink and downlink signals, and dynamically controlling resource allocation using higher layer signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uplink resources are increased in ultra-high density environments, then resource usage efficiency improves, but system performance may deteriorate due to insufficient control
Solution Approach 1:
The patent implements dynamic resource allocation by enabling flexible configuration of uplink and downlink resource periods. The base station can adaptively adjust the number of uplink resources within a period based on actual traffic conditions, allowing the system to optimize resource usage efficiency while maintaining control over system performance through dynamic parameter adjustment
2Productivity
If uplink and downlink resources are configured to overlap in the same time domain, then resource usage efficiency increases, but resource management complexity increases
Solution Approach 1:
The patent segments the time domain into distinct periods with different configurations. By dividing the resource allocation into manageable time segments with specific uplink/downlink patterns, the system achieves overlapping resource configuration while maintaining organized and controllable resource management through structured time-domain segmentation
3Loss of time
If simultaneous uplink transmission and downlink reception is enabled, then delay is reduced, but interference between uplink and downlink signals may increase
Solution Approach 1:
The patent merges uplink and downlink operations in the time domain by allowing simultaneous transmission and reception within configured periods. This overlapping configuration reduces the time loss between uplink and downlink operations while managing interference through coordinated resource allocation and signal processing techniques
