Patent ID: 8437330

Claim:
A subscriber unit comprising: an antenna array; and an antenna array interface coupled to the antenna array; wherein the antenna array and antenna array interface are configured to implement a method; the method comprising: receiving, at the antenna array, wireless transmissions, at least two of which are based on different directional transmissions from a transmitter; generating, using the antenna array interface, a first type of feedback messages to control a power output level of the transmitter; generating, using the antenna array interface, a second type of feedback messages to indicate which of the at least two different directional transmissions from the transmitter supports a higher quality received signal; communicating, using the antenna array, the first and second type of feedback messages over a shared feedback channel to adjust settings of the transmitter; partitioning the shared feedback channel into multiple repeating sequences of frames; and communicating, using the antenna array, either a first or second type of feedback message in a frame of the shared feedback channel depending on a position of the frame in a sequence of periodically repeating frames.
