Self-interference suppression control for a relay node

A computer program product comprising program code portions stored in a non-transitory storage medium, which when executed by a computing device, cause the computing device to:

• actively cancel a signal transmitted from a relay node that leaks back into a receiver of the relay node to suppress self-interference;
• determine one of whether an increase of an amount of self-interference suppression is needed and whether self-interference suppression can be decreased;
• and
• one of increases and decrease, depending on the result of the determination, at least one of a transmit power of the signal transmitted from the relay node and a receive power of the relay node.

A relay node configured to transmit and receive simultaneously using one of a same frequency channel and proximate frequency channels, the relay node comprising:

• a canceller configured to actively cancel a signal transmitted from the relay node that leaks back into a receiver (RX) of the relay node to suppress self-interference;
• a determination component configured to determine one of whether an increase of an amount of self-interference suppression is needed and whether self-interference suppression can be decreased;
• and
• a power control component configured to one of increase and decrease, depending on the result of the determination, at least one of a transmit power of the signal transmitted from the relay node and a receive power of the relay node.
