Claim 22:
23. A nontransitory computer readable storage medium comprising a computer program for determining a beam configuration between a radio transceiver device and a second radio transceiver device, the computer program comprising computer code which, when run on a processing unit of the radio transceiver device, causes the radio transceiver device to:
perform beam searching without relying on previously established control channels for feedback by:
deciding, in a mutually blind beam configuring between the first radio transceiver device and the second radio transceiver device, in what order a transmitting by the radio transceiver device and a receiving by the radio transceiver device will be performed;
the radio transceiver device performing the transmitting and the receiving in the decided order,
wherein the transmitting comprises transmitting a first sounding signal in all transmit beam configurations in a set of transmit beam configurations; and
wherein the receiving comprises receiving, from the second radio transceiver device, a second sounding signal in all receive beam configurations in a set of receive beam configurations; and

determine a beam configuration for the first radio transceiver device based on the receive beam configuration in the set of receive beam configurations in which said second sounding signal having best predetermined metric was received.
