Each of multiple directional transmissions from an antenna array of a subscriber unit are received at a base unit. Based on the detected quality of received signals at the base unit, directional transmissions from the antenna array that produce a higher quality of received signal at the base unit receiver are identified. Feedback messages can be used to notify the subscriber unit which of the directional transmissions are optimal. Consequently, settings of an antenna array at the subscriber unit can be adjusted to support more efficient directional transmissions from the subscriber unit to the base unit.

1. A method comprising: monitoring wireless transmissions, at least two of which are based on different directional transmissions from a transmitter;generating a first type of feedback messages to control a power output level of the transmitter;generating 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 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; andcommunicating 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. 2. The method as in claim 1 further comprising: in a first frame of the shared feedback channel, transmitting a first type of feedback message, andin a frame contiguous with the first frame, transmitting a second type of feedback message. 3. The method as in claim 2, wherein at least one of the first type of feedback message or the second type of feedback message is a single bit. 4. The method as in claim 2, wherein the first type of feedback message is a power control bit. 5. The method as in claim 2, wherein the second type of feedback message is a lobe control bit. 6. The method as in claim 1 further comprising: partitioning a data channel into frames in which data information is transmitted; andfor two successive frames of the data channel, generating two different directional transmissions from the transmitter. 7. The method as in claim 6 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. 8. A method comprising: monitoring wireless transmissions, at least two of which are based on different directional transmissions from a transmitter;generating a feedback message of a first type to control a power output level of the transmitter;generating a feedback message of a second type to indicate which of the at least two different directional transmissions from the transmitter supports a higher quality received signal; andcommunicating the feedback message of the first type and the feedback message of the second type over a feedback channel to adjust settings of the transmitter, whereinthe feedback channel is partitioned into a repeating sequence of frames; andeach of the feedback messages is communicated in a frame of the repeating sequence of frames, wherein a position of that frame in the repeating sequence of frames is used to identify the type of each of the feedback messages. 9. The method as in claim 8 wherein the feedback channel is a shared feedback channel.
