    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 translation: 网络保留多个临时移动组身份（TMGI）。 对于多个保留的TMGI中的每一个，网络在至少一个预配置的多播广播单频网络（MBSFN）区域中建立演进的多媒体广播多播服务（eMBMS）会话。 网络接收到形成包括多个目标UE的自组群通信服务使能器（GCSE）组的请求; 将多个TMGI中的一个分配给附属GCSE组。

    Abstract: Devices and methods are provided for subscription data optimization in a wireless communication system. In one embodiment, the method may involve receiving an update location request from a mobile entity and forwarding the update location request to a subscriber data repository. The method may involve receiving a profile identifier from the subscriber data repository, the profile identifier corresponding to profile parameters for a subscription service for the mobile entity. The method may also involve accessing a lookup table to determine the profile parameters associated with the profile identifier, and determining whether to authorize the subscription service based at least in part on the profile parameters.

    Abstract: This disclosure provides systems, methods and apparatus for non-optimized handoffs for wireless communication. For example, the disclosure may be applied to enhance non-optimized handoff from a long-term evolution (LTE) network to an evolved high rate packet data (eHRPD) network. Systems, methods, and apparatus for reducing the interruption gap during handoffs from an LTE radio access network to an eHRPD network are also discussed. In one aspect, a method is provided for communicating information associated with a handoff of a wireless device from a source network to a target network. The method includes fetching a context for a device communicating via a first radio access system of a first network based in part on a unique identifier from a second radio access system of a second network.
