Abstract

A method of operating a wireless network node may include transmitting a first MIMO downlink communication to a wireless terminal according to a first MIMO rank, and receiving at least one HARQ ACK/NACK, message from the wireless terminal corresponding to the first MIMO downlink communication. A report may be received from the wireless terminal identifying a reported MIMO rank, and a second MIMO rank may be selected for a second MIMO downlink communication responsive to the at least one HARQ ACK/NACK message. The second MIMO downlink communication may be transmitted to the wireless terminal according to the second MIMO rank.
