Abstract
A wireless system comprises a controlling node and two or more antenna processing nodes coupled to the controlling node but separated from each other. The controlling node sends (720) a command to a first one of the two or more antenna processing nodes, instructing the first one of the two or more antenna processing nodes to transmit data to a wireless device. This may be preceded by selecting (715) the first one of the antenna processing nodes based on an estimated signal quality metric corresponding to the wireless device for each antenna processing node. In response to a determination by the controlling node that the wireless device has not successfully decoded the data, the controlling node sends (730) a command to a second one of the two or more antenna processing nodes, instructing the second one of the antenna processing nodes to transmit the data to the wireless device.
