1. A method of securing Positioning Reference Signals (PRS) resources for positioning of a user equipment (UE) in a wireless communication network, the method performed by a network entity and comprising:
sending, to the UE, first configuration data indicative of a period of time during which at least a portion of a PRS resource is to be transmitted using one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols, wherein:
sending the first configuration data occurs prior to transmission of the portion of the PRS resource by a Transmission and Reception Point (TRP) of the wireless communication network; and
the first configuration data excludes at least one transmission parameter value for generating a waveform for each of the one or more OFDM symbols; and
sending, to the UE, second configuration data indicative of the at least one transmission parameter value, wherein sending the second configuration data occurs no earlier than the transmission of the portion of the PRS resource.
