1. A method, in a network node, for handling scheduling of a wireless device in a communications network, wherein the network node is adapted to communicate with the wireless device over a radio channel, the method comprising:
dynamically allocating a set of non-consecutive subframes in which the network node is to transmit data to the wireless device or receive data from the wireless device; and
transmitting, in a downlink control information message (DCI) on a physical downlink control channel (PDCCH), a multi-Time Transmission Interval (TTI) scheduling message to the wireless device, which multi-TTI scheduling message comprises information indicating the dynamically allocated non-consecutive subframes;
wherein the information indicating the dynamically allocated non-consecutive subframes further indicates a multi-TTI subframe pattern corresponding to non-consecutive subframes where the network node is to receive data from the wireless device or transmit data to the wireless device such that the multi-TTI subframe pattern indicates which subframes are on and to be allocated and which subframes are off and not to be allocated;
wherein the multi-TTI scheduling message further comprises information indicating a number of subframes that are on, or information indicating a number of consecutive subframes associated with a time interval; and
transmitting, by the network node in a radio resource control (RRC) message or a medium access control (MAC) message, to the wireless device, an indication of a number of candidate multi-TTI subframe patterns, wherein the downlink control information message transmitted on the physical downlink control channel indicates which one of the candidate multi-TTI subframe patterns is the multi-TTI subframe pattern.
