Beam Configuration Updates Using UE Antenna Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to efficiently update beam and measurement configurations in response to slight movements or rotations of user equipment (UE), leading to suboptimal communication performance, particularly in environments with dynamic user orientations.
Innovation Solution
UEs transmit UE pose and antenna orientation information to a network entity, which determines and transmits updated beam or measurement configurations based on this information, enabling more precise beam management and measurement updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam and measurement configurations are updated frequently to track UE movements, then communication performance is improved, but signaling overhead and power consumption increase
Solution Approach 1:
The system changes the parameter of beam configuration update timing from continuous/frequent updates to event-triggered updates based on UE pose changes. The network entity receives UE pose information and determines to update beam configurations only when pose changes exceed a threshold, thereby maintaining communication performance while reducing unnecessary updates that consume power.
Solution Approach 2:
The system implements a feedback mechanism where the UE transmits pose information to the network entity, which then determines whether beam configuration updates are needed. This feedback loop allows the network to adapt beam configurations based on actual UE movement, improving performance while avoiding unnecessary updates when the UE is stationary or movement is minimal.
2Reliability
If beam configurations are updated in response to UE pose changes, then communication quality is improved, but signaling overhead increases
Solution Approach 1:
The system extracts only the necessary pose information from the UE that is relevant for beam management, rather than transmitting all possible UE state information. The network entity determines beam configuration updates based on this extracted pose information, reducing signaling overhead while maintaining communication quality.
Solution Approach 2:
The system changes the approach from updating all beam parameters frequently to updating only specific beam configuration parameters when pose changes warrant it. The network entity selectively updates beam configurations based on the received pose information, reducing the amount of signaling required while maintaining communication quality.
3Device complexity
If traditional beam management without pose information is used, then system complexity is reduced, but adaptability to dynamic user orientations deteriorates
Solution Approach 1:
The system performs preliminary action by obtaining UE pose information before determining beam configurations. The network entity receives pose information in advance and uses it to proactively determine appropriate beam configurations, improving adaptability to dynamic user orientations while adding minimal complexity compared to reactive beam management.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network entity, one of UE pose information or UE antenna orientation information, wherein the UE antenna orientation information is extracted from the UE pose information. The UE may receive, from the network entity, an updated beam or measurement configuration based at least in part on the UE antenna orientation information. Numerous other aspects are described.
