Abstract:
Techniques are provided for calibrating group delay for a low-tier UE by leveraging the relatively high accuracy of RTT positioning for a premium UE. This can enable online/in-field group delay calibration of low-tier UEs, allowing for low-tier UEs to be calibrated when needed. Depending on desired functionality, techniques for calibration may include the use of RTT measurements with a base station, or an RTT measurement between the low-tier UE and the premium UE.
