Abstract:
1. An antenna weight selector for transmitting data in a communication system from a transmitting node having multiple transmission antenna elements to a receiving node, the antenna weight selector comprising: a channel variability processor configured to determine a channel variability metric for each of two or more sets of candidate antenna weights corresponding to two or more candidate radiation patterns; and a selection processor configured to select, from the two or more sets of candidate antenna weights, at least one set of antenna weights for transmitting data to at least one receiving node based on the determined channel variability metrics; wherein the selection processor comprises a transmission rank selector configured to determine a number of candidate sets of antenna weights satisfying a channel variability requirement and to select at least one transmission rank based on the number, said at least one transmission rank representing a number of data signals to be transmitted simultaneously from the transmitting node to at least one receiving node.
