Waveform-Specific Transmission Parts for Wireless Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face complexity and interference issues due to the use of different waveform types by multiple users or the same user over time, leading to increased scheduling difficulties and potential communication failures.
Innovation Solution
The system configures transmission parts with specific waveform types for user equipment (UE) to communicate with a base station, allowing for dynamic switching between waveform types based on activation and deactivation messages, timer expirations, or capability messages, thereby managing interference and reducing scheduling complexities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different waveform types are used by multiple users or the same user over time, then communication flexibility and adaptability are improved, but scheduling complexity and interference management difficulty increase
Solution Approach 1:
The time domain is segmented into multiple transmission parts, each associated with a specific waveform type. This segmentation allows different waveform types to be scheduled separately, reducing interference and simplifying the scheduling process while maintaining the flexibility to use multiple waveform types.
2Adaptability or versatility
If different waveform types are used by multiple users or the same user over time, then communication flexibility and adaptability are improved, but interference between different waveform types increases
Solution Approach 1:
By dividing the transmission time into separate transmission parts, each dedicated to a specific waveform type, the patent segments the time domain to prevent interference between different waveform types. This ensures that waveform-specific signals do not interfere with each other while still allowing the system to utilize multiple waveform types for different users or time periods.
3Object-affected harmful factors
If transmission parts are configured with specific waveform types, then interference management is improved, but switching between waveform types may introduce latency
Solution Approach 1:
The patent configures multiple transmission parts with different waveform types in advance, so that when a waveform switch is needed, the system can transition between pre-configured parts without significant delay. This preliminary configuration of waveform-specific transmission parts reduces switching latency while maintaining effective interference management.

AI summary
Methods, systems, and devices for wireless communications are described. In some systems, a base station may configure a set of transmission parts each including different sets of time domain resources or different sets of frequency domain resources, or both, and may specify a waveform type for each of the set of transmission parts. In some examples, the base station may configure the set of transmission parts for a user equipment (UE) and, accordingly, the UE and the base station may communicate over a transmission part of the set of transmission parts via signaling that is based on a waveform type that is associated with the transmission part over which the UE and the base station communicate. The base station may control over which transmission part of the set of transmission parts the UE and the base station communicate via a configured timer or via explicit activation and deactivation signaling.
