    摘要: View-upload decoupled (“VUD”) peer-to-peer (P2P) video distribution is provided, in which each peer is assigned to one or more channels to upload, with the assignments made independent of what the peer is viewing. For each assigned channel, the peer distributes (that is, uploads) the channel. This effectively creates semi-permanent distribution swarms for each channel, which are formed by peers responsible for uploading that channel. This can minimize problems associated with channel churn because peers may remain in their assigned distribution groups even if they switch channels. To minimize cross-channel overhead associated with VUD P2P video distribution, substream swarming, in which a peer in a distribution swarm only downloads a small portion of the video stream, called a substream, and uploads the substream to multiple viewers, may be provided. To minimize video streaming quality degradation that may occur during a reconfiguration transient period upon sudden and large increases in video download demands for some channel, VUD P2P video distribution may be integrated with tradition ISO P2P video distribution (which is self-adaptive to the sudden increases in channel popularity).

    摘要: Optocoupler devices and methods for making and using such devices are described. The optocoupler devices contain a light emitting component (a light emitting diode [LED]) and a light receiving component (a phototransistor [PT]) device that are embedded within the substrate, rather than being attached to the surface of the pre-molded substrate. Such a configuration eliminates the bond wires that are often used when the LED and PT are attached on the substrate, improves the electrical performance, and allows the final optocoupler package to be made smaller and thinner. Other embodiments are described.

    摘要: A method for beamforming in a communication network includes generating a plurality of beamforming training (BFT) units associated with a beamforming session between a pair of devices, where each of the plurality of BFT units corresponds to a different beamsteering vector, causing a first non-zero subset of the plurality of BFT units to be transmitted during a first timeslot, and causing a second non-zero subset of the plurality of BFT units to be transmitted during a second timeslot, where the first time timeslot and the second timeslot are not contiguous.

    摘要: A method and system for communication between mobile stations in a wireless relay enhanced cellular communication system. One implementation involves providing a communication resource allocation for peer-to-peer (P2P) communication between a pair of mobile stations during a P2P enhanced time frame wherein one mobile station serves a role as a transparent relay station (MRS) and another mobile station serves a role as a peer mobile station in the pair; and delivering resource allocation information comprising communication periods and frequency subcarriers to the pair of mobile stations, for the mobile station pair to conduct P2P communication therebetween in the P2P enhanced time frame.
