Techniques for transmitting and receiving downlink control information for a set of NOMA downlink transmissions

An apparatus for wireless communication, comprising:

• a processor;
• memory coupled to the processor, wherein the processor is configured to execute code stored in the memory to cause the apparatus to:
• encode downlink control information for a first user equipment (UE) and a second UE based at least in part on a group identifier and a first UE identifier assigned to the first UE, the group identifier associated with a non-orthogonal multiple access (NOMA) group comprising the first UE and at least the second UE;
• transmit a first control channel element for the first UE, the first control channel element comprising downlink control information for the first UE and downlink control information for the second UE, wherein the downlink control information for the second UE comprises a duplicated payload of a second control channel element for the second UE;
• and
• transmit a set of NOMA downlink transmissions to the first UE based at least in part on the downlink control information for the first UE and the second UE.

A non-transitory computer-readable medium for storing instructions executable by a processor, comprising:

• instructions to encode downlink control information for a first user equipment (UE) and a second UE based at least in part on a group identifier and a first UE identifier assigned to the first UE, the group identifier associated with a non-orthogonal multiple access (NOMA) group comprising the first UE and at least the second UE;
• and
• instructions to transmit a first control channel element for the first UE, the first control channel element comprising downlink control information for the first UE and downlink control information for the second UE, wherein the downlink control information for the second UE comprises a duplicated payload of a second control channel element for the second UE;
• and
• instructions to transmit a set of NOMA downlink transmissions to the first UE based at least in part on the downlink control information for the first UE and the second UE.
