    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: Embodiments of techniques and systems for quality of experience (QoE) reporting in wireless systems are described. In some embodiments, user equipment may receive a first value of a first quality of experience (QoE) metric computed during playout of a multimedia asset at the user equipment. The first value may be received at a first layer in a protocol stack of the user equipment from a second layer above the first layer in the protocol stack. The user equipment may provide a first layer report, including data representative of the first value, for wireless transmission from the user equipment to an eNB. Other embodiments may be described and claimed.

    摘要: An ad-hoc network system for computing a proposed number of node-clusters that enable a relative threshold data rate. The ad-hoc network system includes a source terminal, a destination terminal, a plurality of relay terminals, and a cluster determination engine. The source terminal sends a network communication to a destination terminal via a plurality of relay terminals. The cluster determination engine computes a threshold data rate, C, for a number of hops, N, based on a transmission power constraint. The cluster determination engine determines a proposed route for the wireless communication from the source terminal to the destination terminal according to the threshold data rate, C.

    摘要: A method for wireless communication combines OFDMA resource allocation and power control policies with cooperative relaying techniques. The techniques are preferably implemented in a dense wireless network of power-limited mobile devices assisted by mobile relay devices having superior power supplies. Preferably, MIMO beamforming techniques are used to further increase energy efficiency and spectral efficiency beyond the increases provided by ODFMA cooperative relaying.
