Techniques described herein enable multiple radiofrequency networks using different radio technologies to coexist on a same carrier frequency by exploiting various frequency- and/or time-domain sharing of scheduled resources.

A coexistence resource schedule is computed from the communication resource grids define an allocation of sub-carrier and/or timeslot resources among the radio technologies. Radio technologies can then be generated from the data signals in accordance with the coexistence resource schedule and the communication resource grids.
