Adaptive Processing Modes for Wireless Slot Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems at higher frequency bands, such as millimeter wave bands, face challenges in processing timelines like control channel processing and beam switching due to reduced slot lengths, which do not scale with larger subcarrier spacing, leading to difficulties in supporting both single-slot and multi-slot scheduling simultaneously.
Innovation Solution
The implementation of adaptive processing modes that allow user equipment (UE) to switch between single-slot and multi-slot processing modes based on configurations received from the base station, adjusting internal processing blocks and optimizing for multi-slot scheduling by indicating the quantity of slots, reference subcarrier spacing, and configuration parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If larger subcarrier spacing is used in high frequency bands, then phase noise is reduced, but slot length is reduced leading to processing timeline issues
Solution Approach 1:
The patent implements dynamic switching between single-slot processing mode and multi-slot processing mode based on scheduling requirements. The system can adaptively select the appropriate processing mode to match the slot length constraints imposed by larger subcarrier spacing, allowing flexible adjustment of processing timelines without changing the underlying frequency band configuration.
2Speed
If single-slot processing mode is used, then processing speed is fast, but reliability is insufficient for complex communications
Solution Approach 1:
The system dynamically switches between single-slot processing mode for speed-critical operations and multi-slot processing mode for reliability-critical operations. This allows the system to optimize processing speed when conditions permit while ensuring communication reliability when complexity increases, resolving the contradiction between speed and reliability.
3Reliability
If multi-slot processing mode is used, then communication reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent changes the processing mode parameter adaptively based on communication conditions, switching between single-slot and multi-slot modes. This parameter change allows the system to use multi-slot processing (which improves reliability) only when necessary, rather than always using it, thereby reducing the overall signaling overhead while maintaining required reliability levels.
4Adaptability or versatility
If processing mode switching is implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system implements parameter changes by switching between two defined processing modes (single-slot and multi-slot) based on scheduling conditions. This approach provides adaptability to different communication scenarios while limiting complexity by using a discrete set of pre-defined modes rather than continuous parameter adjustment, making the switching mechanism manageable for UE implementation.

AI summary
Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for configuration of switching between a single-slot processing mode and a multi-slot processing mode. For example, a user equipment (UE) may receive, from a base station, a first configuration of a first processing mode that is associated with communications scheduled for a single slot (e.g., a single-slot processing mode). The UE may also receive a second configuration of a second processing mode that is associated with communications scheduled for a plurality of slots (e.g., a multi-slot processing mode). The UE may communicate according to one of the modes, determine to switch to the other different mode, and communicate according to the different mode.
