ABSTRACT:
Transmitting apparatus (10) for transmitting a transmission signal to a receiving apparatus (12) is described. The transmitting apparatus (10) comprises means (30, 32, 34) for transmitting to the receiving apparatus a plurality of transmission beams in accordance with a transmission beam pattern, at least one of the beams carrying the transmission signal, each beam being distinguishable from the or each other beam, means (38, 40) for receiving from the receiving apparatus a feedback signal based on measures of the quality of the transmission beams received at the receiving apparatus, and means (36) for adjusting the transmission beam pattern in dependence on the feedback signal. Corresponding receiving apparatus, and corresponding methods are also described.
