Non-orthogonal multiple access (NOMA)-based channel quality indicator (CQI) reporting

A method of wireless communication performed by a base station, comprising:

• transmitting, to a user equipment (UE), an indication of one or more resources, assigned to multiple UEs, to be used for a channel quality indicator (CQI) report associated with the UE;
• determining a threshold value, associated with a range of channel conditions corresponding to a modulation and coding scheme (MCS) used to communicate with the UE, for the UE based at least in part on an estimate of a buffer delay associated with one or more packets to be transmitted to the UE;
• transmitting, to the UE, an indication of the threshold value;
• and
• monitoring the one or more resources for the CQI report.

A user equipment (UE) for wireless communication, comprising:

• memory;
• and
• one or more processors coupled to the memory, the memory and the one or more processors configured to:
• receive, from a base station, an indication of one or more resources, assigned to multiple UEs, to be used to transmit a channel quality indicator (CQI) report;
• receive, from the base station, an indication of a threshold value,
• wherein the indication of the threshold value is a modulation and coding scheme (MCS) index value associated with a MCS being used to communicate with the UE, and
• wherein the MCS index value corresponds to a range of channel conditions and the threshold value;
• and
• selectively transmit the CQI report on the one or more resources based at least in part on whether a measured channel condition is outside of the range of channel conditions by at least the threshold value.
