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-readable medium for wireless communication are provided. In one configuration, the apparatus may be a UE. The UE receives PTM data from a base station. The UE attempts to decode the PTM data based on an identifier. The UE determines whether to transmit feedback information to the base station based on the attempt to decode the PTM data. In another configuration, the apparatus may be a base station. The base station transmits PTM data to a UE. The base station retransmits the PTM data to the UE based on feedback information associated with the transmitted PTM data.

Abstract: Neutral host networks may offer one or more different services via one or more different service providers, but user equipment (UE) may not necessarily know which services/service providers are offered by the neutral host networks. Accordingly, nodes of the neutral host networks (e.g., an access point, such as an evolved Node B (eNB)) may transmit service discovery information (SDI) to advertise the one or more services or service providers offered by the node and/or the neutral host network. Thus, a UE can receive the SDI via broadcast by the node, dedicated message from the node, etc., and can accordingly present at least a portion of the SDI or determine whether to connect to the node or another node of the neutral host network based at least in part on the SDI.

Abstract translation: 中立主机网络可以经由一个或多个不同的服务提供商提供一个或多个不同的服务，但是用户设备（UE）可能不一定知道中性主机网络提供哪些服务/服务提供商。 因此，中性主机网络（例如，诸如演进节点B（eNB）的接入点）的节点可以发送服务发现信息（SDI）以通告由节点提供的一个或多个服务或服务提供商和/或 中性主机网络。 因此，UE可以通过节点的广播，来自节点的专用消息等接收SDI，并且可以相应地呈现SDI的至少一部分，或者确定是连接到中性主机网络的节点还是另一节点 至少部分基于SDI。

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE determines whether the UE is located within a sub-region of an MBSFN area based on one or more parameters. The UE receives based on the determination a service over broadcast in the sub-region of the MBSFN area or over unicast outside the sub-region. In an aspect, the MBSFN area may be smaller than a unicast area. In an aspect, adaptive retransmission with a group NACK approach may be used to improve an SNR and reliability.

Abstract: A network reserves a plurality of temporary mobile group identities (TMGIs). For each of the plurality of reserved TMGIs, the network establishes an evolved multimedia broadcast multicast service (eMBMS) session in at least one preconfigured multicast broadcast single frequency network (MBSFN) area. The network receives a request to form an adhoc group communications service enabler (GCSE) group including a plurality of target UEs; an assigns one of the plurality of TMGIs to the adhoc GCSE group.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a femto cell. The apparatus determines MBSFN subframes at a frequency of a first base station. The first base station has a first power class, the apparatus has a second power class lower than the first power class. The apparatus determines, in the MBSFN subframes, a first set of symbols used for control information and a second set of symbols used for MBSFN signals by the first base station.

Abstract: Embodiments methods implemented with a server or a processor of a mobile communication device (e.g., a multi-standby communication device) reduce the redundancy information needed to achieve adequate reception service on a first radio access technology (RAT) sharing an RF resource with a second RAT. The device processor may implement at least one tune-away management strategy that mitigates the amount of data for the first RAT that is lost during the tune-away event. Thus, by implementing the one or more tune-away management strategies, the device processor may ensure that less redundancy information overhead is needed to correct or replace lost or partially received data, improving latency, channel usage, and the first RAT's overall reception performance. In some embodiments, a server may implement one or more strategies for including redundancy information into data that is sent to a first RAT to mitigate the negative effects of tune aways on the first RAT.

Abstract translation: 使用移动通信设备（例如，多备用通信设备）的服务器或处理器实现的实施方式减少了在共享RF资源的第一无线电接入技术（RAT）上实现足够接收服务所需的冗余信息，其中第二无线接入技术 鼠。 设备处理器可以实现至少一个调离管理策略，其减轻在调谐事件期间丢失的第一RAT的数据量。 因此，通过实施一个或多个调谐管理策略，设备处理器可以确保需要较少的冗余信息开销来校正或替换丢失或部分接收的数据，改善等待时间，信道使用和第一RAT的整体接收性能。 在一些实施例中，服务器可以实施用于将冗余信息包括在发送到第一RAT的数据中的一个或多个策略，以减轻在第一RAT上调谐的负面影响。
