CBG-based NOMA transmission for a wireless network

A user equipment (UE) comprising:

• a hardware-based transceiver;
• a processor;
• and
• a computer-readable storage media comprising instructions executable by the processor to configure the UE to use the hardware-based transceiver to:
• receive, from a base station, a first message including a first configuration for a code block group-based (CBG-based) transmission scheme;
• receive, from the base station, a second message including a second configuration for a non-orthogonal multiple access (NOMA) transmission scheme;
• transmit, to the base station, uplink data using a CBG-based NOMA transmission scheme based on the first configuration in the first message and the second configuration in the second message;
• receive, from the base station, a decoding result of the CBG-based NOMA transmission, the decoding result including an indication of which CBGs failed to be decoded by the base station;
• and
• determine that the CBGs that failed to be decoded require re-transmission.

A method for a base station to communicate with a user equipment, UE, the method comprising:

• transmitting, by the base station, a first message including a first configuration for a code block group-based (CBG-based) transmission scheme;
• transmitting, by the base station, a second message including a second configuration for a non-orthogonal multiple access (NOMA) transmission scheme;
• receiving, by the base station and from the UE, uplink data transmitted by the UE using a CBG-based NOMA transmission scheme based on the first configuration in the first message and the second configuration in the second message;
• decoding each CBG of the uplink data to provide a decoding result, the decoding result including an indication of which, if any, of the CBGs failed to be decoded;
• and
• transmitting, by the base station and to the UE, the decoding result.
