Abstract

A method, communication apparatus, and machine-readable medium to transmit a downlink signal in a substantially non directional manner from a first communication station of a communication system on a first downlink conventional channel. The first communication station includes a smart antenna system having a plurality of antenna elements. The method includes providing a first set of sequential time intervals for the communication device for communication with its remote communication devices. One or more remote communication devices of the communication system known to the first communication station to be undesired remote communication devices transmit a signal on a first uplink conventional channel. The signals transmitted are received. In one version, they are received at the first communication station, and in another version, by another communication station of the communication system. The signal received are used to configure the smart antenna system for transmitting a downlink signal in a non-directional manner that includes mitigating interference towards the undesired remote communication devices on the first downlink conventional channel.
