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 translation: 提供了广播/组播传输和单播传输之间的平滑过渡的技术。 一种用于管理能够同时进行单播和多播信令的多频/多频无线通信系统（WCS）中的单播和多播服务切换的方法，包括确定对经由专用单播传输提供的内容的总需求是否超过阈值。 该方法包括响应于确定总需求超过阈值，将来自一个频率上的专用单播传输的内容的传输切换到第二或更多个频率上的多播传输。

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, during an active call on a first radio access technology (RAT), that a first condition for performing a handover from the first RAT to a second RAT is satisfied. The UE may determine that the second RAT would trigger a fallback to a third RAT after the handover from the first RAT to the second RAT and that a second condition for performing a handover from the third RAT to the first RAT is satisfied. The UE may refrain from performing the handover from the first RAT to the second RAT based at least in part on the determination that the second RAT would trigger the fallback and the determination that the second condition is satisfied. Numerous other aspects are provided.

Abstract: In one example, a device includes one or more processors implemented in circuitry and configured to execute a Dynamic Adaptive Streaming over HTTP (DASH) aware application (DAA) and a DASH client, and one or more user interfaces. The DAA subscribes to DASH events of a DASH event stream via a first application programming interface (API) between the DAA and a DASH client executed by the one or more processors. The DAA then receives data for one or more DASH events of the DASH event stream from the DASH client via a second API between the DAA and the DASH client, the data for the one or more DASH events specifying interactivity-related content. The DAA then presents the interactivity-related content via the one or more user interfaces. The DAA may further send usage measurements on usage of the interactivity-related content to the DASH client, for reporting to a report server device.

Abstract: Device wakeups can consume a significant amount of power with respect to the device's total power battery lifetime. Aspects of a method, apparatus, and computer-readable medium are presented herein that provide a solution to the problem of battery strain by improving the manner in which a wireless device coordinates device wakeup for multiple applications or multiple operations. An apparatus receives a wakeup time interval from each of a plurality of applications. The apparatus forms a first device wakeup time interval, the first device wakeup time interval including overlapping wakeup time intervals for the plurality of applications. The apparatus schedules a device wakeup during at least the first device wakeup time interval.

Abstract: Distributed computing is disclosed in which a client device accesses a service announcement for a broadcast service in order to retrieve transport parameters describing a data transmission service. The client device obtains a refresh rate from the service description file, which is separate from the data transmission service, wherein the refresh rate relates to a frequency at which the data transmission service updates data in a data transmission provided by the data transmission service. The client device uses the transport parameters to access the data transmission to receive the data. Once the data is received, the client device will delay any subsequent access to the data transmission to get updated data for a delay time based at least in part on the refresh rate.

Abstract: Systems and methods adapted for providing heterogeneous media services in communication systems, such as using transport layer security deferral and/or medium redirect, are disclosed. In operation according to embodiments, heterogeneous media services may be facilitated by obtaining, by a hybrid broadcast receiver of a receiver device, a computer parsable object comprising information regarding content segment availability and access, wherein the hybrid broadcast receiver is adapted to obtain content via both broadcast and broadband connections for a streaming client of the receiver device. The hybrid broadcast receiver of embodiments may further operate to evaluate the computer parsable object for one or more content segment entries indicating transport layer security is to be invoked with respect to a connection used for obtaining one or more content segments and to overwrite the one or more content segment entries preventing the transport layer security from being invoked by the streaming client.
