摘要:
Briefly, in accordance with one or more embodiments, an application function module interacts with an application on a remote device that utilizes dynamic policy and charging control to receive an adaptive multimedia stream. A policy and charging rules function (PCRF) module implements policy and charging control decisions, and a policy and charging enforcement function (PCEF) module enforces policy decisions received from the PCRF. The remote device provides session information including a media presentation description to the application function module to provide the multimedia stream to the remote device at a specified quality of service.

摘要:
An approach to enhance quality of experience (QoE) in a wireless multimedia communication system is disclosed. A signaling mechanism is provided to make application-layer parameters of a multimedia application to be accessible in one or more network interfaces including an air interface, an access network interface, and a core network interface. Also, the application-layer parameters may be included in quality of service (QoS) class definitions to make the application-layer parameters accessible at the one or more network interfaces. The signaling mechanism and inclusion of application-layer parameters into the QoS class definitions is to enable the QoE-aware link adaptation, resource allocation, joint source channel coding based cross-layer optimizations.
摘要:
Link adaptation parameters for encoding of a source are selected to minimize distortion between the source and a reconstructed source induced by transmission of the source over a multiple input multiple output (MIMO) channel. Such distortion-awareness and associated joint source-channel coding ideas to support link adaptation over MIMO channels may affect system architectures for MIMO systems. CQI feedback mechanisms may ensure that these distortion-aware MIMO link adaptation techniques are applicable for downlink channels, under different forms of link adaptation, including MS-controlled vs. BS-controlled link adaptation, long-term vs. dynamic link adaptation, and presence vs. absence of distortion-awareness at the BS, for different kinds of video coding including single-layer compression and layered compression.

摘要:
Techniques are described to transmit multimedia content to a mobile station using a combination of a mobile/cellular network as well as a TV Whitespace (TVWS) network. Scalable video coding can be used to transmit a baseline layer of multi-media content using the mobile/cellular network and one or more enhancement layers over the TVWS channels. Joint source-channel coding can be used to adjust the transmission scheme used by mobile/cellular and/or TVWS based on end user experience.
