Abstract: A user equipment (UE) registers on a first Public Land Mobile Network (PLMN) and, while in an idle mode, receives a Multimedia Broadcast Multicast Services (MBMS) service. The UE determines whether to perform a periodic network reselection search for a higher priority PLMN while in the idle mode, wherein the UE determines whether to perform the periodic network reselection search based on reception of the MBMS service. The UE may postpone the periodic network reselection search for a period of time while the UE receives the MBMS service in the idle mode. The UE may postpone the periodic network reselection search for a period of time while the UE receives the MBMS service in the idle mode. The UE may interleave the periodic network reselection search with the reception of transmission bursts of the MBMS service, the search being performed on frequencies other than that of the MBMS transmission.

Abstract: In some cases, V2X systems may send warning messages. The warning messages may be sent over short distances. The warning messages may be useful over wider distances. Some systems may us MBMS from a V2X proximity broadcast. Electronic communications devices, such as UEs may be unaware of the MBMS. A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be an RSU. The RSU receive a V2X message from a UE. The RSU may broadcast information associated with the V2X message. The RSU may send the information associated with the V2X message to a network entity for a point-to-multipoint broadcast. The method, an apparatus, and a computer program product for wireless communication may also use V2X messages that include bootstrapping information to tune to an MBMS broadcast.

Abstract: Techniques are provided for smooth transition between broadcast/multicast transmission and unicast transmission. A method for managing unicast and multicast services switching in a multi-band/multi-frequency wireless communications system (WCS) capable of both unicast and multicast signaling includes determining whether an aggregate demand for a content provided via dedicated unicast transmissions exceeds a threshold. The method includes switching transmission of the content from the dedicated unicast transmissions on one frequency to a multicast transmission on a second or more frequencies in response to determining that the aggregate demand exceeds the threshold.
