Patent ID: 8908784

Claim:
A method of transmitting data from a radio access network node to a wireless terminal using a multiple-input-multiple-output, MIMO, antenna array including a plurality of MIMO antenna elements, the method comprising: generating a plurality of unmapped symbol blocks wherein each of the unmapped symbol blocks includes a plurality of symbols; mapping symbols of a first one of the plurality of unmapped symbol blocks to first and second mapped symbol blocks, so that the first mapped symbol block includes symbols of the first unmapped symbol block, and so that the second mapped symbol block includes symbols of the first unmapped symbol block; precoding the symbols of the first mapped symbol block to provide precoded symbols of a first MIMO precoding layer using a MIMO precoding vector; precoding the symbols of the second mapped symbol block to provide precoded symbols of a second MIMO precoding layer using the MIMO precoding vector; and transmitting each of the precoded symbols of the first and second MIMO precoding layers through the MIMO antenna elements of the MIMO antenna array to the wireless terminal using a same time-frequency-resource-element, TFRE.
