    摘要： 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.

    摘要： A beamforming method is disclosed that includes performing sequential beam transmissions in multiple directions and receiving replies to the transmissions (i.e. a sector search). The received transmissions can include information or channel parameters such as direction of arrival, signal to noise ratio, signal strength, etc., for each sector. Utilizing the parameters transmitted or fed back by the receiver, the transmitter can store control vectors that dictate a beam that can be utilized to commence a beam refinement procedure. In addition, the parameters can be utilized to select and implement a custom sequence to refine the communication channel between the device and the controller. The custom sequence can significantly reduce the time required to create a channel with acceptable qualities such that efficient high speed network communications can be conducted. Other embodiments are also disclosed.

    摘要： In a wireless communications network, a wireless device may examine the received signal to determine the strength of the received signal, and also determine the level of interference and noise. If a retransmission is needed due to a message being incorrectly received, these factors may then be processed to estimate whether the probable cause of poor reception is interference from a neighboring network. If such interference is the likely cause, the retransmission may be changed to a different time and/or to different frequencies in a subsequent frame, so that the interference from the neighboring network is less likely to reoccur.
