Abstract: Methods, systems, and devices for wireless communication are described. Data for a broadcast or multicast service may be sent over a control channel. A network device may broadcast a message to indicate a plurality of enhanced multimedia broadcast multicast service (eMBMS) services offered by the network. The mobile device may transmit an indication to the network device identifying an eMBMS service of interest. The network device may transmit a configuration message before broadcasting or multicasting data of the eMBMS service of interest. The configuration message may notify the mobile device of a control channel on which to receive the data related to the eMBMS service. The network device may then broadcast or multicast the eMBMS service data on the control channel. The data may be segmented at a particular protocol layer and mapped to several transmission time intervals within each repetition of the control channel.

Abstract: Techniques are provided for smooth transition between broadcast/multicast transmission and unicast transmission. A method for managing unicast and multicast services switching in a multi-band/multi-frequency wireless communications system (WCS) capable of both unicast and multicast signaling includes determining whether an aggregate demand for a content provided via dedicated unicast transmissions exceeds a threshold. The method includes switching transmission of the content from the dedicated unicast transmissions on one frequency to a multicast transmission on a second or more frequencies in response to determining that the aggregate demand exceeds the threshold.

Abstract: An example client device includes a middleware unit for receiving media data either via a broadcast service or a unicast service, depending on whether the broadcast service is available. The client device also includes a streaming client, such as a Dynamic Adaptive Streaming over HTTP (DASH) client. The DASH client sends requests to retrieve media data via the middleware unit. The middleware unit may cache media data received via the broadcast service, such that even when the broadcast service is not active, if the streaming client requests media data that was previously received via the broadcast service, the middleware unit may provide the media data to the streaming client from the cache, rather than requesting the media data from an external server device specified in the request from the streaming client.

Abstract translation: 示例性客户端设备包括用于经由广播服务或单播服务来接收媒体数据的中间件单元，这取决于广播服务是否可用。 客户端设备还包括流客户端，例如动态自适应流HTTP over（DASH）客户端。 DASH客户端通过中间件单元发送请求来检索媒体数据。 中间件单元可以缓存经由广播服务接收到的媒体数据，使得即使当广播服务不活动时，如果流客户端请求先前经由广播服务接收到的媒体数据，则中间件单元可以将媒体数据提供给 而不是从来自流客户端的请求中指定的外部服务器设备请求媒体数据。

In one example, a communications device is equipped to provide a parity portion of titles in a channel of a service to a plurality of UEs at a first time, receive, from a UE at a second time, a request to access a title of the one or more titles, and provide an enablement item, to the requesting UE, which is a portion of the requested title that, when processed with the provided parity portion of the requested title, is sufficient to allow the requesting UE to decode and access to the requested title. In an aspect, the parity portion may be a parity portion of a fountain code encoded title, and the enablement item may be repair symbols of the fountain code encoded title.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a first service and determines a potential upload time period including an aggregation time period. The potential upload time period is for uploading a reception report for the first service. The apparatus receives a second service before expiration of the aggregation time period. The apparatus determines whether to generate first reporting information for the received first service and second reporting information for the received second service. The apparatus aggregates the first reporting information and the second reporting information based upon the determination to generate both the first reporting information and the second reporting information.
