Methods and arrangements for a coordination of frequency band selections for interfering uplink transmissions in a cellular network

A base station (105) for assisting in a coordination of frequency band selections for interfering uplink transmissions in a cellular network (100), which base station (105) serves a first cell (110) in the cellular network (100), wherein the cellular network (100) further comprises a second cell (115) and a third cell (120) the base station (105) comprising:

• a selecting unit (600), configured to select a first frequency band (41) and a second frequency band (42), which first frequency band (41) is to be used in the first cell (110) for uplink transmissions, from which uplink transmissions an estimated interference in the second cell (115) exceeds a first threshold, and which second frequency band (42) is to be used in the first cell (110) for uplink transmissions, from which uplink transmissions an estimated interference in the third cell (120) exceeds a second threshold, and
• an informing unit (610) configured to inform a serving base station (125, 105) of the second cell (115) and a serving base station (130, 105) of the third cell (120) about the performed selection (501), thereby assisting the serving base station (125, 105) of the second cell (115) and the serving base station (130, 105) of the third cell (120) in coordinating their respective frequency band selection with that of the base station (105).

The base station (105) according to any one of claims 10-13, wherein the selecting unit (600) is further configured to select a bandwidth for the respective first frequency band (41) and/or second frequency band (42) based on a number of uplink transmissions, for which number of uplink transmissions the respective first frequency band (41) and/or the respective second frequency band (42) is to be used.
