Mode-Based Spatial Parameters for Half- and Full-Duplex Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient methods for configuring spatial parameters for half-duplex and full-duplex communications, leading to potential dropped or failed transmissions due to inadequate updates in spatial configurations when switching between modes or when the user equipment (UE) moves or rotates.
Innovation Solution
A UE indicates separate spatial parameters for half-duplex and full-duplex communications through configuration messages, allowing it to select the appropriate set based on the communication mode, thereby optimizing antenna configurations for efficient transmission.

Engineering Contradiction Analysis
1Reliability
If separate spatial parameters are configured for half-duplex and full-duplex communications, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments spatial parameters into separate configurations for half-duplex and full-duplex communications. The UE maintains distinct spatial parameter sets (e.g., different antenna ports, beam directions, or spatial filters) tailored to each communication mode, allowing optimized performance for each mode without interference from the other configuration.
Solution Approach 2:
The patent implements dynamic selection of spatial parameters based on the current communication mode. The UE and network entity dynamically switch between half-duplex and full-duplex spatial configurations according to operational requirements, enabling adaptive optimization of transmission reliability while managing complexity through mode-based parameter selection.
2Reliability
If spatial parameters are updated when UE moves or rotates, then communication reliability is improved, but use of energy increases
Solution Approach 1:
The patent employs feedback mechanisms where the UE monitors its movement and rotation status, and the network entity receives updates about UE position changes. Based on this feedback, spatial parameters are updated only when necessary (e.g., when movement exceeds a threshold or rotation changes the optimal beam direction), maintaining reliability while avoiding unnecessary energy consumption from continuous updates.
Solution Approach 2:
The patent implements periodic evaluation of UE position and orientation to determine when spatial parameter updates are needed. Instead of continuous updating, the system periodically checks whether movement or rotation has occurred that would degrade communication quality, updating parameters only at these periodic intervals when conditions warrant it, thus balancing reliability with energy efficiency.

AI summary
Methods, systems, and devices for wireless communication are described. In a wireless communication system, a first wireless node may transmit a configuration message indicating one or more spatial configurations for communicating with a second wireless node. A spatial configuration may include one or more different sets of spatial parameters for half-duplex communications and full-duplex communications between the wireless nodes. In some examples, the first wireless node may select a first set of spatial parameters for half-duplex communications or a second set of spatial parameters for full-duplex communications based on an explicit indication or a resource configuration. The wireless nodes may perform half- or full-duplex communications using the first or second set of spatial parameters, respectively, in accordance with the configuration message.
