The busy burst (BB) concept for time division duplex (TDD) systems mitigates excessive interference by means of receiver feedback; potential transmitters that sense a BB above a certain threshold must refrain from transmitting. As strong received BB power, due to TDD channel reciprocity, implies that the interference caused to an ongoing transmission is equally strong, a protection radius around active receivers is established. In order to boost the sum-rate in shared spectrum networks, a novel combination of the BB protocol with interference cancellation at the receiver is presented in this paper.
