Publication number: 20160183226Abstract: Embodiments contemplate devices and techniques for receiving unicast and multicast transmissions over a downlink (DL) shared channel in parallel, for example an LTE DL shared channel (SCH). For example, one or more hybrid automatic repeat request (HARQ) entities may be configured to perform retransmissions of the multicast and/or unicast messages. Common and/or dedicated (e.g., separate) HARQ entities may be utilized for retransmission. The multicast downlink shared channels may be activated and/or deactivated on demand.

Publication number: 20140019593Abstract: Quality-based optimizations of a delivery process of streaming content may be enabled. The optimization may take the form of quality-based switching. To enable quality-based switching in a streaming client, the client may have access to information about the quality of an encoded segment and/or sub-segment. Quality-related information may include any number of added quality metrics relating to an encoded segment and/or sub-segment of an encoded video stream. The addition of quality-related information may be accomplished by including the quality-related information in a manifest file, including the quality-related information in segment indices stored in a segment index file, and/or providing additional files with quality-related segment information and providing a link to the information from an MPD file. Upon receiving the quality-related information, the client may request and receive a stream that has a lower bitrate, thereby saving bandwidth while retaining quality of the streaming content.Type: ApplicationFiled: July 10, 2013Publication date: January 16, 2014Inventors: Yuriy Reznik, Eduardo Asbun, Zhifeng Chen, Rahul Vanam
