摘要
A user equipment (UE) can receive, from an eNodeB, a serving PLMN system information block (SIB)19 for a carrier frequency of a serving PLMN of the UE. The UE can acquire inter-frequency and inter-PLMN discovery system information acquisition assistance signaling information from the SIB19. The UE can process a non-serving PLMN SIB19 for one or more carrier frequencies of a non-serving PLMN using the inter-frequency and inter-PLMN discovery system information acquisition assistance signaling information. The UE can identify inter-frequency and inter-PLMN discovery announcement rate information and monitoring control configuration information for the one or more carrier frequencies of the non-serving PLMN to enable the UE to perform device-to-device (D2D) discovery with a UE in the non-serving PLMN according to the inter-frequency and inter-PLMN discovery announcement rate information and monitoring control configuration information.

The present application is a continuation of U.S. patent application Ser. No. 15/557,070 filed Sep. 8, 2017 which is a 371 Nationalization of PCT Application No. PCT/US2015/00357 filed Dec. 24, 2015 which claims priority to U.S. Provisional Patent Application No. 62/144,777, filed Apr. 8, 2015 the entire specification of which is hereby incorporated by reference in its entirety for all purposes.
Wireless mobile communication technology uses various standards and protocols to transmit data between a node (e.g., a transmission station) and a wireless device (e.g., a mobile device). Some wireless devices communicate using orthogonal frequency-division multiple access (OFDMA) in a downlink (DL) transmission and single carrier frequency division multiple access (SC-FDMA) in an uplink (UL) and a sidelink (SL) transmissions. Standards and protocols that use orthogonal frequency-division multiplexing (OFDM) for signal transmission include the third generation partnership project (3GPP) long term evolution (LTE), the Institute of Electrical and Electronics Engineers (IEEE) 802.16 standard (e.g., 802.16e, 802.16m), which is commonly known to industry groups as WiMAX (Worldwide interoperability for Microwave Access), and the IEEE 802.11 standard, which is commonly known to industry groups as WiFi.
