Abstract
Systems and methods according to the exemplary embodiments enable non-cognitive radio devices to operate as if they were cognitive radio devices. A pilot radio device analyzes a local radio environment and broadcasts a spectrum map message which indicates, for example, available radio resources in the local radio environment. A non-cognitive radio device receives the spectrum map message and uses the information in the spectrum map message to select a radio resource for its own transmissions and/or receptions.
Claims20
A method for generating and transmitting radio environment information to enable non-cognitive radio devices to operate as cognitive radios, the method comprising the steps of:
- receiving, by a pilot radio device, a broadband radio sample associated with a radio environment;
- analyzing, by said pilot radio device, said broadband radio sample to identify channels in said radio environment which are available for use;
- generating, by said pilot radio device, a spectrum map message which indicates at least some of said channels which are available for use;
- and
- transmitting, by said pilot radio device, said spectrum map message.
A pilot radio device which generates and transmits radio environment information to enable non-cognitive radio devices to operate as cognitive radios, the pilot radio device comprising:
- a broadband radio receiver configured to receive a broadband radio sample associated with a radio environment;
- a processor configured to analyze said broadband radio sample to identify channels in said radio environment which are available for use, and further configured to generate a spectrum map message which indicates at least some of said channels which are available for use;
- and
- a transmitter configured to transmit said spectrum map message.
A method for enabling a non-cognitive radio device to operate as a cognitive radio device, the method comprising the steps of:
- receiving, by said non-cognitive radio device, a spectrum map message which indicates channels which are locally available for use;
- selecting, by said non-cognitive radio device, a channel for use by said radio device;
- configuring, by said non-cognitive radio device, said non-cognitive radio device to transmit using said channel;
- and
- transmitting, by said non-cognitive radio device, said radio signal on said channel.
A non-cognitive radio device comprising:
- a transceiver configured to transmit and receive radio signals, including reception of a broadcast channel which includes a spectrum map message that indicates channels which are currently locally available for usage by said non-cognitive radio device;
- and
- a processor configured to process said spectrum map message and to select at least one of said channels which are currently available for usage by said non-cognitive radio device and further configured to control said transceiver to transmit and receive said radio signals on said selected at least one channel.
