Abstract

A method of transmitting data from a wireless network node over a MIMO channel to a wireless terminal may include transmitting first and second transport data blocks to the wireless terminal over the MIMO channel using a first time-frequency-resource-element (TFRE). Responsive to receiving a NACK message from the wireless terminal corresponding to the first and second transport data blocks transmitted using the first TFRE, the first and second transport data blocks may be retransmitted to the wireless terminal over the MIMO channel using a second TFRE.
