| 20100110995 | METHOD AND SYSTEM FOR PERFORMING TASKS ON COLLABORATING WIRELESS DEVICES - A method and system for performing functions on multiple physical devices, is provided. One implementation involves connecting the physical devices via wireless links, discovering function capabilities of each physical device, wherein a function capability of a physical device comprises a local resource and a virtual resource, and collaborating among the physical devices by wireless communication to provide a set of functions including discovered function capabilities of the collaborating physical devices, wherein each function of the function base can be mapped to one or more of said resources for execution. | 2010-05-06 |
| 20100110996 | Dynamic Fractional Frequency Reuse in OFDMA Networks - A method allocates resources in an orthogonal frequency-division multiple access (OFDMA) network including a set of base stations (BSs), and a set of mobile stations (MSs) for each BS. Each cell includes a center and edge zone. A node weighted constraint graph is constructed for the network. Maximal independent sets in the graph are searched as sub-channels are allocated to the MSs in edge zones. Remaining bandwidth is allocated to the MSs in the center zones. Power is assigned to the sub-channels so that inter-cell interference is minimized and traffic load is maximized. | 2010-05-06 |
