    Abstract: Systems, methods, and devices of the various embodiments enable evolved Multimedia Broadcast Multicast Service (“eMBMS”) network sharing, content sharing, and roaming. The various embodiments may enable Multimedia Broadcast Multicast Service (“MBMS”) service continuity across different public land mobile networks (“PLMNs”) by associating the same MBMS services providing identical content in different PLMNs with each other. In an embodiment, service discovery may be provisioned to a receiver device when or after the receiver device is attached to a PLMN. In an embodiment, content sharing across different PLMNs may be supported by a user service description indicating the different temporary mobile group identifiers (“TMGIs”) of the same service across different PLMNs. In another embodiment, content sharing across different PLMNs may be supported by a user service description indicating the same TMGI for the same service across different PLMNs. In an embodiment, MBMS keys may be shared across PLMNs.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a cyclic prefix duration for orthogonal frequency division multiple access symbols is determined. The cyclic prefix duration is calculated to reduce inter-symbol interference associated with a transmitter located at a distance that is more than 5 kilometers from one or more user equipment. Subcarrier spacing is determined and a symbol size for the symbols is determined. One or more of an enhanced Node B and a user equipment is configured with the cyclic prefix duration, the subcarrier spacing and the symbol size.

    Abstract: In a first configuration, a UE receives, from a service provider, a certificate authority list. The certificate authority list is at least one of integrity protected or encrypted based on a credential known by the UE and the service provider and stored on a smartcard in the UE. The UE authenticates a server using the received certificate authority list. In a second configuration, the UE receives a user service discovery/announcement including a reception report configuration and an address of a server. The UE sends a protected reception report to the server based on the reception report configuration. In a third configuration, the UE receives a protected broadcast announcement and communicates based on the broadcast announcement. The broadcast announcement is at least one of integrity protected or encrypted based on a credential known by the UE and stored on a smartcard in the UE.

    Abstract: Techniques are provided for managing simultaneous unicast and multicast/broadcast services. For example, there is provided a method operable by a user equipment (UE) or the like, that involves transmitting, upon initial connection with a wireless communication system, a first message indicating one or more capabilities of the UE. The method may further involve transmitting a second message indicating that the UE is receiving or is about to receive a multicast/broadcast service. The method may also involve receiving, as a result of the second message, data scheduled in accordance with one or more predetermined rules.
