1. A method, in a controlling node of a distributed wireless system that comprises the controlling node and two or more antenna processing nodes communicatively coupled to the controlling node but spatially separated from each other and from the controlling node, the method comprising:
sending a first command to a first one of the two or more antenna processing nodes, the first command instructing the first one of the two or more antenna processing nodes to transmit first data to a wireless device; and
responsive to determining that the wireless device has not successfully decoded the first data, sending a second command to a second one of the two or more antenna processing nodes, the second command instructing the second one of the two or more antenna processing nodes to transmit the first data to the wireless device.
