Antenna control system and method

1. 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 and 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 feedback channel to adjust settings of the transmitter;

providing feedback information to one or more other subscriber units so that their corresponding transmit settings comprising at least power output levels are minimized for a particular antenna orientation and position in a shared wireless communication system.

2. The subscriber unit as in claim 1 , wherein the antenna array and antenna array interface are further configured to implement the method further comprising:

in a first frame of the shared feedback channel, transmitting a first type of feedback message, and

in a frame contiguous with the first frame, transmitting a second type of feedback message.

3. The subscriber unit as in claim 2 , wherein the antenna array and antenna array interface are further configured to implement the method wherein at least one of the first type of feedback message or the second type of feedback message is a single bit.

4. The subscriber unit as in claim 2 , wherein the antenna array and antenna array interface are further configured to implement the method wherein the first type of feedback message is a power control bit.

5. The subscriber unit as in claim 2 , wherein the antenna array and antenna array interface are further configured to implement the method wherein the second type of feedback message is a lobe control bit.

6. The subscriber unit as in claim 1 , wherein the antenna array and antenna array interface are further configured to implement the method further comprising: partitioning a data channel into frames in which data information is transmitted; and

for two successive frames of the data channel, generating two different directional transmissions from the transmitter.

7. The subscriber unit as in claim 6 , wherein the antenna array and antenna array interface are further configured to implement the method further comprising:

receiving a feedback message at the transmitter indicating which of the two different directional data transmissions results in a higher quality received signal.
