context: GANSS Additional Navigation Models And Time Recovery, GANSS Additional UTC Models, GANSS Auxiliary Information, DBDS Corrections, or BDS Ionospheric Grid Model IEs. - If the GANSS Generic Data IE does not contain the GANSS ID IE, the corresponding GANSS is âGalileoâ. - The DGANSS Corrections IE contains one or several DGANSS Information IE(s), each of them associated with a GANSS Signal. A DGANSS Information IE for a particular GANSS that does not contain the GANSS Signal ID IE is by default associated with the default signal defined in TS 25.331 [16], clause 10.3.3.45a. - The DBDS Corrections IE contains one or several DBDS information IE(s), each of them associated with a GANSS Signal. A DBDS Information IE for a particular GANSS that does not contain the GANSS Signal ID IE is by default associated with the default signal defined in TS 25.331 [16], clause 10.3.3.45a. - The GANSS Real Time Integrity IE contains one or several Satellite Information IEs, each of them associated with a
description: The Angle of Arrival (AOA) is a physical layer measurement that defines the estimated angle of a user with respect to a reference direction, determined at the Base Station (BS) antenna for an uplink channel corresponding to a specific User Equipment (UE). In distributed antenna systems, AOA measurements may vary across different cell portions and can be utilized for location-related functions, such as determining UE location using AOA and Cell ID.
explanation: AOA is classified as a Measurement because it quantifies a physical characteristic (the angle of arrival) in a telecommunications system. The text describes its role as a measurable parameter used for location determination.
