Abstract: A wireless communication network and method are described for enhancing cell-edge performance of a wireless transmit/receive unit (WTRU). The WTRU may establish a connection with a plurality of sites via respective downlinks (DLs). Each DL may include at least one DL component carrier (CC) that operates on a frequency that is the same or different than one or more of the other CCs. The sites may manipulate their transmit power for a particular CC operating frequency such that the distance from a particular one of the sites to its cell boundary may become larger by increasing its transmit power on the particular frequency, and the distance from at least one of the other sites to its respective cell boundary may become smaller by decreasing its transmit power on the particular frequency. Thus, a coverage overlap between different CC frequencies may be created while maintaining a frequency reuse pattern of one.

Abstract: A method, a device and computer readable storage media facilitate providing screen content including a plurality of video frames that are displayed by a computing device. During coding of the screen content, a suitable predictor is found that is used to code pixel blocks from one or more frames. The suitable predictor is found by selecting a pixel block of a current frame, conducting a direction based search by comparing pixel blocks within a search window of a reference frame with the selected pixel block of the current frame to determine whether a match exists, and, in response to a determination that no sufficient match has been found, conducting a feature oriented search by comparing pixel blocks of the reference frame with the selected pixel block of the current frame to find a suitable match based upon a common feature.

Abstract: A heat-transfer imaging system and a method of using the same. The heat-transfer imaging system includes a heat-transfer sheet and an activating ink. The heat-transfer sheet and the activating ink are specially formulated so that only the areas of the heat-transfer sheet onto which the ink has been printed become adhesive under heat-transfer conditions. This effect may be achieved by designing the sheet to include an ink-receptive coating whose melting temperature is higher than that typically encountered during normal heat-transfer conditions and by formulating the activating ink to include a plasticizer that, when printed onto the ink-receptive coating, lowers the melting temperature of the ink-receptive coating sufficiently so that the modified melting temperature falls within the temperature range encountered during heat-transfer.
