    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. An apparatus, e.g., user equipment (UE), receives a reporting requirement for one or more Multicast-Broadcast Single Frequency Network (MBSFN) physical layer parameters. The UE obtains the one or more MBSFN physical layer parameters including at least one parameter corresponding to a reference signal, and creates a report based on the obtained one or more MBSFN physical layer parameters. The UE may obtain the one or more MBSFN physical layer parameters using user-plane or control-plane based mechanisms. The user-plane mechanism involves the use of a modified version of the reporting mechanism for Quality of Experience (QoE) metrics. The control-plane mechanism involves the use of a modified version of the reporting mechanism for the Minimization of Drive Tests (MDT) metrics.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which at least one bit rate for allocating network resources from a broadcast-multicast service center (BM-SC) is received. The network resources are then allocated based on the at least one bit rate. Moreover, all evolved Node Bs (eNBs) in a broadcast/multicast area are informed of the network resource allocation. Additionally, the network resources are allocated for a session based on a first bit rate, wherein the first bit rate is greater than a guaranteed bit rate (GBR), and the network resource allocation is adjusted to a second bit rate based on the occurrence of an event, wherein the second bit rate is equal to GBR.

    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: Diversity enhancement for multiple carrier systems is disclosed which includes generation of a multiplexed multicarrier radio frequency (RF) signal having N carriers organized to be accessed at a rate of one carrier access per multicast channel (MCH) scheduling period (MSP) per carrier of the N carriers, thereby requiring N accesses per MSP duration across the N carriers. The method may also include the base station transmitting the RF signal to a user equipment (UE). In other aspects, the diversity enhancements include the UE receiving a multiplexed multicarrier RF signal having N carriers. The UE may access the N carriers by performing one carrier access per MSP per carrier of the N carriers, thereby performing N accesses per MSP duration across the N carriers.

    Abstract: Extended duration cyclic prefixes with lower overhead are disclosed in which an integer multiple sequence of carriers above the nominal 300 carrier-per-25 resource blocks (RBs) definition are selected to reduce the cyclic prefix overhead below the normative 20%. Sets of durations are then provided associated with each such integer multiple sequence of carriers that allow for the combined duration of the symbol duration and extended duration cyclic prefix to result in an integer number of carriers for each RB.
