摘要：
In a method for improved HARQ retransmissions of data streams in a node in a MIMO wireless communication system, transmitting S1 data across a plurality of available MIMO links according to a predetermined rank and radio resource allocation, receiving S2 a retransmission request for at least part of the transmitted data, reducing the rank S3 of the retransmissions by selecting a subset of the plurality of available MIMO links. Subsequently, adaptively reallocating S4 available radio resources to the selected subset, and retransmitting S5 the requested data on said selected subset according to the reduced rank and radio resource re-allocation.
