    摘要： An electronic device for sending a message is described. The electronic device includes a processor and instructions stored in memory that is in electronic communication with the processor. The electronic device determines whether a first picture is a Clean Random Access (CRA) picture. The electronic device also determines whether a leading picture is present if the first picture is a CRA picture. The electronic device further generates a message including a CRA discard flag and an initial CRA Coded Picture Buffer (CPB) removal delay parameter if a leading picture is present. The electronic device additionally sends the message.

    摘要： A User Equipment (UE) for allocating power for uplink transmission to an evolved Node B (eNB) is described. The UE includes a processor and memory that is in electronic communication with the processor. Executable instructions are stored in the memory. The UE obtains a power headroom. The UE also obtains a threshold. Also, the UE reduces power consumption if the power headroom is less than the threshold. The power headroom is based on the difference between a maximum uplink transmit power and an estimated uplink transmit power.

    摘要： In an exemplary embodiment, a streaming client is playing a media stream that is being streamed from a streaming server. The media stream is being played at a certain playback rate. While the media stream is being played, the level of a streaming buffer is monitored. If it is determined that the level of the streaming buffer is below a defined lower limit, then the playback rate is set equal to a value that is less than the intended playback rate for the media stream. The specific value of the playback rate depends on the level of the streaming buffer.

    摘要翻译： 在示例性实施例中，流客户端播放正在从流服务器流传输的媒体流。 媒体流正以一定的播放速度播放。 当播放媒体流时，监视流缓冲区的级别。 如果确定流缓冲器的电平低于定义的下限，则将重放速率设置为等于小于媒体流的预期播放速率的值。 播放速度的具体值取决于流缓冲器的级别。
