摘要
Disclosed are techniques to determine angle of departure (AoD) of signals transmitted from a set of transmission points associated with a transmitter (e.g., a base station, a user equipment (UE)). In an aspect, the set of transmission points are collocated and transmit coherent signals. A receiver (e.g., UE, network entity) determines phase difference of arrivals (PDoAs) of the signals. Based on the PDoAs and locations of the set of transmission points, the AoD can be calculated. When the UE is the receiver, the network entity can send a base station almanac (BSA) message to the UE indicating the set of transmission points and their locations.
