In one embodiment, an apparatus comprises at least one processor and a memory storing a set of computer instructions, configured. The processor is configured to cause the apparatus to determine a linear phase variation between at least first and second transmissions from first and second transmission points based at least in part on a propagation delay difference between the first and second transmissions, and transmit the phase variation information for at least the first and the second transmissions. An apparatus configured to operate as a transmission point in a network receives linear phase variation information indicating phase variation experienced by at least one user equipment resulting from a propagation delay difference between at least the apparatus and a second apparatus operating as a second transmission point and manages transmission so as to control phase variation resulting from the propagation delay difference.

The method also includes providing for communication with the mobile terminal in accordance with the one of real-valued modulation or complex-valued modulation that was determined.
