The invention allows coordinating transmissions and receptions for over-the-air communication between uncoordinated base stations of an OFDM based cellular radio network. A radio resource dedicated for OTAC between uncoordinated base stations of an OFDM based cellular radio network is divided into subchannels. Deployment information of the uncoordinated base stations is obtained at a mobility management unit. Transmission allocation information is determined at the mobility management unit based on the obtained deployment information, the transmission allocation information comprising for each of the uncoordinated base stations their respective at least one symbol in said subframe of said dedicated radio resource and their respective at least one subchannel for use in their respective over-the-air communication transmissions, such that simultaneous over-the-air communication transmissions between an uncoordinated base station and its target uncoordinated base station are prevented. To the uncoordinated base stations are transmitted their respective determined transmission allocation information.
