System and method for secondary communications with directional transmission
System and method for exploiting spatial spectrum holes (SSH) in the time/spectrum/location of wireless resources. A method comprises setting a directional antenna to a first transmission direction, determining a state of a spectrum band in the first transmission direction, transmitting information in the first transmission direction to the receiver in response to determining that the spectrum band state is idle and that the receiver lies within a coverage area of a transmitter, and transmitting the information in the first transmission direction to a first relay in response to determining that the spectrum band state is idle and that the receiver lies without the coverage area of the transmitter.
