A method, 19, and machine-readable medium for transmitting a downlink signal in a substantially non directional manner from a communication station to a first remote communication device on a downlink channel. The communication station includes a smart antenna system having an array of antenna elements. The method includes determining a first downlink smart antenna processing strategy for transmitting in a first non-directional manner, transmitting a first downlink message from the communication station in the first non-directional manner using the first downlink smart antenna processing strategy, and repeating transmitting the first downlink message from the communication station in a second non-directional manner. The repeated transmitting is non-identical repetition to facilitate the interference environment being different in the repetition. |

DETAILED DESCRIPTION A Cellular System and its Smart Antenna Base Station Referring to FIG.
1 there is generally shown a cellular wireless communication system 100 having at least two base stations, a first base station 102 and at least one second base station 111, with the first base station 102 including a smart antenna system that has an array of antenna elements 104.
System 100 also includes a plurality of remote, possibly mobile user terminals 105, 106, 107, and 108 for conducting bi-directional packet communications with first base station 102, and a plurality of remote, possibly mobile user terminals 109 and 110 for conducting bi-directional packet communications with the other base stations, such as second base station 111.
First base station 102 is said to be associated with user terminals 105, 106, 107, and 108, while second base station 111 is associated with user terminals 109 and 110.
The first base station 102 is coupled to a network such as a data and/or voice network.
The one or more second base stations 111 may also be coupled to the same network.
In one embodiment, the first base station and other base stations 111 are coupled to the Internet.
FIG.
2A shows one embodiment of first base station 102.
The base station includes a smart antenna system 203 that is an adaptive antenna array system.
Smart antenna system 203 has an array of antenna elements 104, a set of transmitters and a set of receivers, implemented in one embodiment as a set of transmitter/receivers ("transceivers") 206, with one transmitter and one receiver for each individual antenna element of array 104, and a spatial processor 208 for performing uplink and downlink smart antenna processing.
Uplink smart antenna processing includes combining the signals received from the individual antenna elements via the set of transceivers, and downlink smart antenna processing includes generating multiple versions of a signal for transmission from the individual antenna elements via the set of transceivers.
A control computer 210 controls the smart antenna processing
