Wireless Device Positioning Measurement Adaptation for Antenna Schemes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, particularly in LTE, the lack of awareness by User Equipment (UE) of antenna transmission schemes used in neighboring cells leads to degraded positioning measurement quality, as the UE may make incorrect assumptions about signal channels, resulting in potential measurement failures and reduced accuracy.
Innovation Solution
Implementing methods in wireless devices and network nodes to determine and adapt to different antenna transmission schemes used in cells, compensating for potential measurement errors by determining the antenna transmission scheme used by cells and adjusting measurement procedures accordingly, and configuring transmission schemes for improved positioning accuracy.

Engineering Contradiction Analysis
1Measurement precision
If the UE performs positioning measurements without awareness of the antenna transmission scheme used in neighboring cells, then the positioning measurement can be performed, but the measurement accuracy is degraded due to incorrect assumptions about signal channels
Solution Approach 1:
The network node transmits antenna transmission scheme information to the UE in advance, before the positioning measurement is performed. This allows the UE to have the necessary information about the antenna transmission scheme used in neighboring cells prior to making measurements, enabling correct assumptions about signal channels and improving measurement accuracy
Solution Approach 2:
The network node acts as an intermediary that provides the antenna transmission scheme information to the UE. This intermediary transmission of information bridges the gap between the UE's lack of awareness and the need for accurate positioning measurements, allowing the UE to compensate for measurement errors
2Reliability
If the UE makes assumptions about signal channels without knowing the actual antenna transmission scheme, then the positioning measurement can proceed, but measurement failures occur due to incorrect channel assumptions
Solution Approach 1:
The network node provides feedback information about the antenna transmission scheme to the UE, enabling the UE to adjust its measurement procedure accordingly. This feedback mechanism improves the reliability of positioning measurements by ensuring the UE uses correct channel assumptions based on the actual transmission scheme being used
