1. A user equipment for supporting a positioning reference signal (PRS) mechanism for downlink angle of departure (DL-AoD) positioning, comprising:
at least one processor; and
at least one memory including instructions which, when executed by the at least one processor, cause the user equipment at least to:
receive a configuration message including at least one first configuration and one or more sets of additional configurations, wherein the at least one first configuration comprises information that identifies at least one first set of time frequency resources for at least one reference signal (RS), and the one or more sets of additional configurations identifies time frequency resources for at least one set of positioning reference signals (PRSs);
perform at least one first measurement of at least one reference signal for beam measurements according to the at least one first configuration, wherein the at least one reference signal comprises at least one wide-beam reference signal;
wherein the at least one first configuration is associated with one or more sets of additional configurations for beam measurements;
wherein the at least one set of positioning reference signals comprises at least one narrow-beam positioning reference signal;
perform based on the at least one first measurement at least one second measurement of at least one set of positioning reference signals according to at least one set of additional configurations of the one or more sets of additional configurations; and
transmit at least one angle of departure (AoD) measurement report after performing the at least one second measurement.
