Downlink control information (dci) design for multi-component carrier scheduling

A user equipment (UE), comprising:

• at least one memory device;
• at least one transceiver;
• and
• at least one processor coupled with the at least one memory device and the at least one transceiver, the at least one memory device storing instructions that are executable by the at least one processor, individually or in any combination, to cause the UE to:
• receive a downlink control information (DCI) message having a DCI format, the DCI message scheduling a data communication over two or more carriers, the DCI message comprising a hybrid automatic repeat request (HARQ) process ID field and one or more sets of a modulation and coding scheme field, a redundancy version field, and a new data indicator field (MCS, RV, NDI) for each carrier scheduled for data communication by the DCI message, wherein a number of the (MCS, RV, NDI) sets is based at least in part on a number of spatial layers for which data communication on said each carrier is scheduled;
• determine, based on the received DCI message, a number of the two or more carriers for which the data communication is scheduled;
• and
• communicate, based on the determining, the data communication over the determined number of carriers.

A method of wireless communication performed at a user equipment (UE), the method comprising:

• receiving a downlink control information (DCI) message having a DCI format, the DCI message scheduling a data communication over two or more carriers, the DCI message comprising a hybrid automatic repeat request (HARQ) process ID field and one or more sets of a modulation and coding scheme field, a redundancy version field, and a new data indicator field (MCS, RV, NDI) for each carrier scheduled by the DCI message, wherein a number of the (MCS, RV, NDI) sets is based at least in part on a number of spatial layers for which data communication on said each carrier is scheduled;
• determining, based on the received DCI message, a number of the two or more carriers for which the data communication is scheduled;
• and
• communicating, based on the determining, the data communication over the determined number of carriers.
