Data and control multiplexing for uplink MIMO with carrier aggregation and clustered-DFT

An evolved Node B (eNB) comprising:

• a transmitter configured to transmit information to a wireless transmit receive unit (WTRU);
• and
• a receiver configured to:
• receive, from the WTRU, at least a first layer of a plurality of layers, wherein the at least first layer includes at least channel quality indicator (CQI) bits multiplexed with data bits of a first transport block, wherein the first transport block has a first modulation and coding scheme (MCS), and further wherein the CQI bits are received via the first layer based on the first MCS of the first transport block;
• and
• receive, from the WTRU, at least a second layer of the plurality of layers, wherein the at least second layer includes at least rank indicator (RI) bits, hybrid automatic repeat request (HARQ) acknowledge/non-acknowledge (ACK/NACK) bits, and a second transport block, wherein the CQI bits are not received via the second layer.
