SBFD Time-Domain Unit Configuration for Simpler 5G Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, the configuration of multiple types of time-domain units in sub-band full duplex (SBFD) technology leads to complexities in data transmission, particularly for terminal devices, as they often support only one-directional transmission in a sub-frame, limiting flexibility and efficiency.
Innovation Solution
The method involves determining a single type of time-domain unit for data transmission, ensuring that terminal devices and network devices allocate and utilize only one type of time-domain unit for transmissions, such as SBFD or non-SBFD symbols, to simplify and stabilize data transmission processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of time-domain units are configured in SBFD technology, then transmission flexibility is improved, but transmission complexity increases
Solution Approach 1:
The patent changes the parameter of time-domain unit configuration from multiple types to a single type (either all uplink or all downlink symbols within a subframe). This parameter change resolves the contradiction by maintaining transmission flexibility through configurable single-type selection while reducing transmission complexity by eliminating the need to handle multiple mixed types simultaneously.
2Reliability
If terminal devices support one-directional transmission in a sub-frame, then transmission reliability is improved, but transmission efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by making the transmission direction configurable and changeable at different time instances. The network can dynamically configure subframes as uplink-only or downlink-only based on traffic conditions, allowing the system to adapt between reliability-focused and efficiency-focused modes, thereby resolving the contradiction between transmission reliability and efficiency.
