  • Patent number: 9788329
    Abstract: A system and method for reducing interference between wireless terminals communicating in a mobile ad-hoc network (MANET). Interference is reduced by dividing the MANET into a number of geographical areas having a specific size and shape. Each geographical area is assigned a time slot during which wireless terminals located in the respective geographical area may transmit to other wireless terminals. The time slots are assigned such that geographical areas having the same time slot are far enough away from each other that wireless terminals located in such same time slot geographical areas are outside the interference range of each other.

  • Patent number: 9642116
    Abstract: A method and system determines an absolute Multicast-Broadcast Single Frequency Network (MBSFN) configuration based on a threshold. First saved radio resources and first wasted radio resources are calculated. The absolute MBSFN configuration is set as the final MBSFN configuration when the first saved radio resources are greater than or equal to the first wasted radio resources. When untrue, the absolute MBSFN configuration plus an adjacent cell pool is set as the final MBSFN configuration based on the final MBSFN configuration achieving a maximum value of second saved radio resources minus second wasted radio resources. When both of these conditions are untrue, the absolute MBSFN configuration minus an MBSFN cell pool is set as the final MBSFN configuration based on the final MBSFN configuration achieving a maximum value of third saved radio resources minus third wasted radio resources.
