摘要： Interference levels occurring at one or more stations in a wireless network, where each of said one or more stations is a base station or a relay station. The measured interference levels are mapped by building a first matrix including noise plus interference occurring at each of the one or more stations, respectively, and scheduled transmissions at predetermined times by each relay station respectively are mapped by building a second matrix. The first matrix and the second matrix are multiplied in order to determine the noise plus interference impact upon each base station by each relay station so that a network schedule can be generated in order to increase bandwidth efficiency in the network.
