Systems and methods are described for scheduling transmission for a first radio access technology (RAT) and a second RAT including, but not limited to, determining likelihood of successful transmission for each of a plurality of frames associated with the second RAT based on an activity pattern associated with the first RAT. Transmission cost associated with each of a plurality of data blocks is determined. Each of the plurality of data blocks is transmittable via the second RAT. A first data block of the plurality of data blocks is assigned to a frame of the plurality of frames based, at least in part, on the likelihood of successful transmission associated with the frame and the transmission cost associated with the first data block (the data with highest priority/delay sensitivity is assigned to the subframe with highest likelihood of success).
