A method of interference management in a wireless network includes determining a level of interference within a wireless receiver and transmitting a signal indicative of excessive interference. Within a wireless transmitter, a beam forming vector or a sub-set of transmitter antenna is randomly selected from a set of transmitter antenna available to the transmitter and switching signal transmission from a preceding transmission mode to a transmission mode using the selected beamforming vector or the selected antenna sub-set, following receipt of a signal indicative of excessive interference. It is then determined, within the receiver, whether a level of interference has improved since the transmission of the signal. If not, a signal indicative of a deterioration of said level of interference is sent. If the signal indicative of a deterioration of the level of interference is received at the transmitter, the transmitter reverts to using the preceding transmission mode for signal transmission.
