Not sure if I understood

Not sure if I understood question correctly, See below what 3GPP specs says about it

Angle of Arrival (AoA) -AoA defines the estimated angle of a user with respect to a reference direction. The reference direction for this measurement shall be the geographical North, positive in a counter-clockwise direction. The AoA is determined at the eNB antenna for an UL channel corresponding to this UE.

From 3GPP 36.305 -> 8.3        Enhanced cell ID positioning methods
8.3.1       General

In the Cell ID (CID)-based method, the UE position is estimated with the knowledge of the geographical coordinates of its serving eNodeB. Enhanced Cell ID (E-CID) positioning refers to techniques which use additional UE and/or E‑UTRAN radio resource related measurements to improve the UE location estimate. For E-UTRAN access, these measurements may include [20, 21]:

UE measurements ([20], [21]):

-     Reference signal received power (RSRP);

-     Reference Signal Received Quality (RSRQ);

-     UE Rx – Tx time difference. 

E-UTRAN measurements ([20], [21]):

-     eNB Rx – Tx time difference

-     Timing Advance (T_ADV):

-     Type1: T_ADV = (eNB Rx – Tx time difference) + (UE Rx – Tx time difference)

-     Type2: T_ADV = eNB Rx – Tx time difference;

-     Angle of Arrival (AoA).

Various techniques exist to use these measurements to estimate the location of the UE. The specific techniques are beyond the scope of this specification.
