Abstract
Techniques for managing operation over a communication medium shared between Radio Access Technologies (RATs) are disclosed. In one example, one or more parameters of a Time Division Multiplexing (TDM) communication pattern may be set to define activated periods and deactivated periods for communication over the medium. A first interlace may be selected among a plurality of interlaces for communication over the medium, the first interlace being reserved for a first operator. During the first interlace, transmission over the medium may be cycled in accordance with the TDM communication pattern, and deactivated during a second interlace among the plurality of interlaces that is reserved for a second operator.
