1. A wireless transmit/receive unit (WTRU) comprising:a processor; and
a receiver; and
the receiver configured to receive a first physical downlink control channel (PDCCH) of a first cell of a first network node and to receive a second PDCCH of a second cell of a second network node, wherein the first cell and the second cell have different carrier frequencies, wherein the first PDCCH is associated with a first radio network terminal identifier (RNTI) and includes a first modulation and coding set (MCS), wherein the second PDCCH is associated with a second RNTI and includes a second MCS, wherein the first and the second RNTI are different and the first and the second MCS are different;
the receiver is further configured to receive a first physical downlink shared channel (PDSCH) of the first cell based on the first PDCCH and to receive a second PDSCH of the second cell based on the second PDCCH, wherein the reception of the first PDSCH and the second PDSCH overlap in time.
