UE Antenna Panel Selection for High-Precision Wireless Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in achieving high-precision positioning, particularly with devices having multiple antenna panels, as they lack effective methods to control which antenna panel is used for measuring or transmitting reference signals, leading to inaccuracies in position calculations.
Innovation Solution
The network entity or user equipment controls which antenna panel is used for measuring or transmitting reference signals, providing panel information to the network, and accounting for panel location and orientation in position calculations, enabling centimeter-level accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antenna panels are used for positioning, then positioning coverage and signal reception capability are improved, but measurement precision deteriorates due to lack of control over which antenna panel is used
Solution Approach 1:
The patent segments the antenna system into multiple identified antenna panels and controls which panel is used for positioning measurements. The network entity identifies and specifies particular antenna panels for positioning operations, separating the positioning function from the general communication antenna system to ensure consistent, controlled measurements.
Solution Approach 2:
The patent introduces an intermediary control mechanism where the network entity mediates between the UE's multiple antenna panels and the positioning measurement process. The network entity identifies which antenna panel should be used and ensures consistent panel selection, acting as a mediator that coordinates the complex multi-panel system to achieve precise positioning.
2Measurement precision
If antenna panel location and orientation are accounted for in position calculations, then measurement precision is improved to centimeter-level accuracy, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by having the network entity pre-identify and pre-determine which antenna panel should be used for positioning measurements before the actual measurement takes place. The network entity prepares the positioning configuration in advance, specifying the antenna panel selection criteria and location/orientation parameters that will be used in subsequent calculations.
Solution Approach 2:
The patent implements feedback mechanisms where the UE provides measurement results indicating which antenna panel was actually used, and the network entity uses this feedback to verify and correct position calculations. The network entity receives measurement reports containing antenna panel identification and uses this feedback information to refine the positioning accuracy.

AI summary
Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) may receive, from a network entity, a request to perform a positioning operation. The UE may identify at least one antenna panel to be used to perform the positioning operation, either by selecting the at least one antenna panel to be used to perform the positioning operation or by receiving, from the network entity, information that identifies the at least one antenna panel to be used to perform the positioning operation. The UE may perform the positioning operation using the identified at least one antenna panel.
