Method and apparatus for facilitating packet scheduling for a hybrid communication network
Methods, apparatus and computer program products facilitate scheduling in a hybrid communication network with mobile devices of the first type such as device-to-device (D2D) mobile terminals and second type of mobile terminals such as cellular terminals. A scheduling activity factor is calculated based at least in part on a total number of both mobile devices of the first type and second type of mobile terminals, which is sent to at least one first type of mobile terminal.
