A subscriber unit, including an antenna array and an antenna array interface coupled to the antenna array, is described. Wireless transmissions, at least two of which are based on different directional transmissions from a transmitter, are received at the antenna array. Feedback messages are generated using the antenna array interface. The feedback messages are communicated using the antenna array to adjust settings of the transmitter.
1. A method in a subscriber unit for uplink (UL) power control, the method comprising: sending messages from the subscriber unit to a base station via an access channel;receiving a control message from the base station, the control message received in an opposite direction from the messages sent to
1. A method in a subscriber unit for uplink (UL) power control, the method comprising: sending messages from the subscriber unit to a base station via an access channel;receiving a control message from the base station, the control message received in an opposite direction from the messages sent to the base station via the access channel, wherein the control message is received from the base station via a feedback channel, the control message having a single power control bit to indicate power level changes for the subscriber unit, and further wherein the control message provides the single power control bit during a first time slot and the control message provides transmitter setting information during a second time slot, the transmitter setting information including antenna lobe settings for multi-antenna subscriber units;adjusting one or more transmitter settings in the subscriber unit based on the power control bit; and transmitting signals from the subscriber unit utilizing the adjusted transmitter settings. 2. The method of claim 1 wherein the power control bit indicates whether transmit power of the subscriber unit is to be increased or decreased. 3. The method of claim 2 wherein the power control bit in a first state indicates that the transmit power of the subscriber unit is to be increased by a pre-selected amount and the power control bit in a second state indicates that the transmit power of the subscriber unit is decreased by the pre-selected amount. 4. The method of claim 1 wherein multiple control messages each having single power control bits are received over multiple frames. 5. A subscriber unit comprising: an antenna;an antenna controller coupled with the antenna;a receiver coupled with the antenna;a transmitter;control logic coupled with the transmitter, the control logic to send messages from the subscriber unit to a base station via an access channel;control logic coupled with the receiver, the control logic to receive a control message from the base station, the control message received in an opposite direction from the messages sent to the base station via the access channel;wherein the control message is received from the base station via a feedback channel, the control message having a single power control bit to indicate power level changes, wherein the control message provides the single power control bit during a first time slot and the control message provides transmitter setting information during a second time slot, the transmitter setting information including antenna lobe settings for multi-antenna subscriber units; andwherein the control message is to cause the antenna controller to adjust one or more transmitter settings based on the power control bit, and to transmit signals utilizing the adjusted transmitter settings. 6. The subscriber unit of claim 5 wherein the power control bit indicates whether transmit power of the subscriber unit is to be increased or decreased. 7. The subscriber unit of claim 6 wherein the power control bit in a first state indicates that the transmit power of the subscriber unit is to be increased by a pre-selected amount and the power control bit in a second state indicates that the transmit power of the subscriber unit is decreased by the pre-selected amount. 8. The subscriber unit of claim 5 wherein multiple control messages each having single power control bits are received over multiple frames. 9. A method in a base station for uplink (UL) power control, the method comprising: receiving messages at the base station from a subscriber unit via an access channel;transmitting a control message from the base station to the subscriber unit, the control message transmitted in an opposite direction from the messages received at the base station via the access channel, wherein the control message is transmitted from the base station to the subscriber unit via a feedback channel,the control message having a single power control bit to indicate power level changes for the subscriber unit, wherein the control message provides the single power control bit during a first time slot and the control message provides transmitter setting information during a second time slot, the transmitter setting information including antenna lobe settings for multi-antenna subscriber units;wherein the control message is to cause one or more subscriber units to adjust one or more transmitter settings in the subscriber unit based on the power control bit; andreceiving signals from the subscriber unit utilizing the adjusted transmitter settings. 10. The method of claim 9 wherein the power control bit indicates whether transmit power of the subscriber unit is to be increased or decreased. 11. The method of claim 10 wherein the power control bit in a first state indicates that the transmit power of the subscriber unit is to be increased by a pre-selected amount and the power control bit in a second state indicates that the transmit power of the subscriber unit is decreased by the pre-selected amount. 12. The method of claim 9 wherein multiple control messages each having single power control bits are received over multiple frames. 13. A base unit comprising: an antenna;a transceiver coupled with the antenna;control logic coupled with the transceiver;wherein the control logic is to receive messages at the base station from a subscriber unit via an access channel;wherein the control logic is further to transmit a control message from the base station to the subscriber unit, the control message transmitted in an opposite direction from the messages received at the base station via the access channel,wherein the control message is transmitted from the base station to the subscriber unit via a feedback channel;wherein the control message includes having a single power control bit to indicate power level changes in the subscriber unit, wherein the control message provides the single power control bit during a first time slot and the control message provides transmitter setting information during a second time slot, the transmitter setting information including antenna lobe settings for multi-antenna subscriber units;wherein the control logic is further to cause the subscriber unit to adjust one or more transmitter settings based on the power control bit; andwherein the control logic is further to receive signals utilizing the adjusted transmitter settings. 14. The base unit of claim 13 wherein the power control bit indicates whether transmit power of the subscriber unit is to be increased or decreased.
