1. A method in a first base station for assisting in a coordination of frequency band selections for interfering uplink transmissions in a cellular network, wherein the first base station serves a first cell in the cellular network, wherein the cellular network further comprises a second cell and a third cell neighboring the first cell, the method comprising:
selecting from a cell-edge band allocated to the first cell, a first frequency band and a second frequency band, wherein the first frequency band is to be used in the first cell for uplink transmissions from users expected to interfere with users in the second cell at a level exceeding a first threshold, and wherein the second frequency band is to be used in the first cell for uplink transmissions from users expected to interfere with users in the third cell at a level exceeding a second threshold; informing a serving base station of the second cell and a serving base station of the third cell about the frequency-band selections, thereby assisting the serving base station of the second cell and the serving base station of the third cell to select respective frequency bands for use by users in the second and third cells that minimize interference among the cells; receiving from the serving base station of the third cell, information related to a fourth frequency band, wherein the fourth frequency band has been selected by the serving base station of the third cell to be used in the third cell for uplink transmissions from users expected to interfere with users in the second cell at a level exceeding a fourth threshold; and the first base station extending the first frequency band to include the fourth frequency band; wherein a fifth frequency band has been selected by the serving base station of the second cell to be used for uplink transmissions in the second cell from users expected to interfere with users in the first cell at a level exceeding a fifth threshold; wherein the fifth frequency band has further been selected by the serving base station of the third cell to be used for uplink transmissions in the third cell from users expected to interfere with users in the first cell at a level exceeding a sixth threshold; and wherein the selecting further comprises the first base station extending one of the first frequency band and the second frequency band to include one or more resource blocks which have been released from the fifth frequency band, or wherein the selecting further comprises the first base station releasing one or more resource blocks from one of the first frequency band and the second frequency band, wherein the one or more resource blocks is to be included in the fifth frequency band. |
