This invention describes a wireless system comprising a plurality of transmitters and receivers, wherein each transmitter has between 1 and n antennas and each receiver has between 1 and m antennas wherein one of said transmitter is arranged to transmit to one of the receivers, said one transmitter is controlled in dependence on at least one of at least one parameter of said transmitters, at least one parameter of said receiver, and at least one parameter of a wireless environment between said transmitter and said receiver.

Transmitting and receiving methods

The present invention relates to a method and a communication system wherein stations communicate on a wireless interface. The method includes the steps of including beam identity information into signals transmitted on multiple beams provided by a first station, receiving at a second station signals transmitted from the first station, and identifying beams via which the second station received signals from the first station based on said identity information. At least one beam for transmission on the wireless interface between the stations is then selected. A station configured for the communication comprises antenna means for receiving signals transmitted from the other station on multiple beams and a controller for identifying beams based on beam identity information associated with signals received from the other station.
