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: 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.
