Abstract
In some embodiments a beamforming method is disclosed. The method can include transmitting a beam having a channel defined by a maximum ration transmission vector (MRT) and receiving a first response from a receiver, where the first response has first information such as parameters related to the transmitted beam. Using the parameters and the initial MRT another directional transmission can be made. A similar process can determine a maximum combining ratio for a receiver. Set up communications between the transmitter and the receiver can be reduced by omitting data from transmission that can be acquired by other means such as from memory or calculations. Additional embodiments are also disclosed.
