1. An apparatus of a User Equipment (UE), configured as a Proximity Services (ProSe) enabled UE, the apparatus comprising:
processing circuitry to configure the UE to perform a ProSe Direct Discovery process, wherein as part of the ProSe Direct Discovery process, the processing circuitry is configured to:
encode, for transmission over a PC3 interface to a ProSe Function in a Home Public Land Mobile Network (HPLMN), a discovery request message for an announcing procedure, the announcing procedure including transmission of one or more announcements over a PC5 interface, wherein the discovery request message for the announcing procedure includes a PC5 technology (PC5_tech) parameter comprising a bitmap indicating whether only one, both or neither of two or more PC5 radio technologies are preferred to be used by the UE for the announcing procedure, wherein the two or more PC5 radio technologies include at least Evolved Universal Terrestrial Radio Access (E-UTRA) and wireless local area network (WLAN), wherein the bitmap comprises at least one bit indicating whether E-UTRA is preferred to be used by the UE for the announcing procedure and at least one bit indicating whether WLAN is preferred to be used by the UE for the announcing procedure; and
decode a discovery response message for the announcing procedure, the discovery response message for the announcing procedure received over the PC3 interface from the ProSe Function in the HPLMN, wherein the discovery response message for the announcing procedure includes a ProSe application code and the PC5_tech parameter to indicate a PC5 radio technology authorized to be used for the ProSe application code; and
memory configured to store the ProSe application code.
