1. A network node comprising a radio frequency communications interface and a controller, said network node being configured to service at least one first radio frequency communication device being configured for both network communication and for device-to-device communication with a second radio frequency communication device, wherein said controller is configured to:

  • determine if a restriction of a scheduling policy is necessary for said first radio frequency communication device;

    select a scheduling policy accordingly; and

    allocate communication resources according to said selected scheduling policy to said first radio frequency communication device,wherein if it is determined said restriction of said scheduling policy is not necessary, then said scheduling policy is one which enables network communication and device-to-device communication in said same transmission time interval, and if it is determined said restriction of said scheduling policy is necessary, then said scheduling policy is one which enables either network communication or device-to-device communication in said same transmission time interval; and

    receive a recommendation on a scheduling policy from said first radio frequency communication device and to base said determination if a restriction of said scheduling policy is necessary on said recommendation;

    configure the first radio frequency communication device for generating said recommendation based on such configuration;

    only transmit said allocated resources to said first radio frequency communication device during a mode selection occasion if the scheduling policy enables simultaneous network communication and device-to-device communication in said same transmission time interval.
