The present disclosure relates to a CDMA communication node arrangement comprising at least two spatially separated antenna units, at least one radio unit and at least one control unit. Each antenna unit has at least one corresponding coverage area and is connected to the central unit. The control unit is arranged to alter transmitting properties of at least a first antenna unit, to a user terminal, such that more or less power is transmitted by the first antenna unit in a dedicated channel. The control unit is arranged to monitor received inner power control loop commands when at least a second antenna unit is communicating with the user terminal, and to determine whether said first antenna unit should start or stop communicating with the user terminal, or continue as before, based on how the inner power control loop commands respond. The present disclosure also relates to a corresponding method.
