A method for managing spectrum sharing in a wireless communication network includes identifying a set of users in the wireless communication network which shares a spectrum of communication, classifying the set of users into multiple subsets of users, and scheduling, within a given time slot, one subset of users among the multiple subsets of users to transmit and receive data at the same time so that the scheduled subset of users shares the spectrum of communication. The users in a subset are selected by comparing the desired channel strength with the sum of strengths of the strongest interference from that user and the strongest interference to that user, all values in dB scale.
