Abstract
An apparatus and method of facilitating cooperation within a cognitive radio communication system. The cooperation system facilitated in the communication system by another communication system. The apparatus include: a receiver to receive an uplink signal from a mobile station and a cooperation signal from a second communication system, wherein the cooperation signal is associated with the uplink signal; an evaluator to evaluate a contribution of the cooperation signal with respect to detection of the uplink signal; and a radio resource management unit to control an available radio resource for the second system according to the contribution of the cooperation signal.
Claims18
A base station in a first communication system, the base station comprising:
- a receiver to receive an uplink signal from a mobile station and a cooperation signal from a second communication system, wherein the cooperation signal is associated with the uplink signal;
- an evaluator to evaluate a contribution of the cooperation signal with respect to detection of the uplink signal;
- and
- a radio resource management unit to control an available radio resource for the second communication system according to the contribution of the cooperation signal.
A base station comprising:
- a receiver to receive an uplink signal of a first mobile station;
- a cooperation signal generator to generate a cooperation signal associated with at least one of soft decision information for performing a soft decision for the received uplink signal;
- digital information that is generated by quantizing the received uplink signal;
- and hard decision information for performing a hard decision for the received uplink signal;
- a transmitter to transmit the cooperation signal to a second base station;
- and
- a radio resource recognition unit to recognize an available radio resource allocated by the second base station based on a contribution of the cooperation signal with respect to detection of the uplink signal by the second base station.
A base station of a first communication system, the base station comprising:
- a receiver to receive an uplink signal from a source mobile station;
- a first signal generator to generate a first signal associated with at least one of soft decision information for performing a soft decision for the received uplink signal, digital information that is generated by quantizing the received uplink signal, and hard decision information for performing a hard decision for the received uplink signal;
- a transmitter to transmit the first signal to a destination mobile station;
- an evaluator to evaluate a contribution of a second signal generated by a second communication system, the second signal associated with the received uplink signal, with respect to the destination mobile station detecting the received uplink signal;
- and
- a radio resource management unit to control availability of radio resource to a second communication system according to the evaluated contribution of the second signal.
A method of operating a base station in a first communication system, comprising:
- receiving at a receiver an uplink signal from a mobile station and a cooperation signal from a second communication system, wherein the cooperation signal is associated with the uplink signal;
- detecting by a detector the received uplink signal using the received cooperation signal;
- evaluating by an evaluator a contribution of the cooperation signal with respect to detection of the uplink signal;
- and
- controlling by a radio resource management unit availability of radio resource to the second communication system according to the contribution of the cooperation signal.
A computer-readable recording medium storing a program configured to cause a base station to:
- receive an uplink signal from a mobile station and a cooperation signal from a second communication system, wherein the cooperation signal is associated with the uplink signal;
- detect the received uplink signal using the received cooperation signal;
- evaluate a contribution of the cooperation signal with respect to detection of the uplink signal;
- and
- control availability of a radio resource to the second communication system according to the contribution of the cooperation signal.
