Abstract
A method, device, and machine readable medium to communicate from a base station having a smart antenna system to a user terminal. The method includes providing a downlink channel for transmitting downlink data from the base station to the user terminal, providing an associated channel for the base station to receive an uplink response signal from the user terminal in response to the downlink data. The associated channel is associated, and has a predefined relationship, with the downlink channel. The method further includes providing an uplink data channel, distinct from the associated uplink channel, for the base station to receive uplink data from the user terminal. The method also includes receiving the uplink response signal at the base station, determining a downlink smart antenna processing strategy using the received uplink response signal, sending downlink data from the base station to the user terminal using the determined downlink smart antenna processing strategy, and receiving uplink data from the user terminal on the uplink data channel.
