Power control design for non-orthogonal multiple access

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

• determining a transmit power for a data or control transmission, wherein the data or control transmission is a grant-free transmission;
• performing the data or control transmission using non-orthogonal multiple access (NOMA) in accordance with the transmit power;
• determining that the data or control transmission has failed;
• and
• performing a retransmission of the data or control transmission using a grant-based approach.

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

• determining at least one of a downlink path loss value or an uplink path loss value associated with a base station and the UE;
• receiving an uplink grant from the base station,
• wherein the uplink grant identifies a power control value associated with the base station;
• and
• determining a transmit power for a data or control transmission based at least in part on at least one of the downlink path loss value or the uplink path loss value and the power control value.

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

• transmitting, to a user equipment (UE), configuration information using at least one of system information, radio resource control signaling, or a dynamic uplink grant, wherein the configuration information identifies one or more target receive powers for a data or control transmission and corresponding configurations for uplink power control associated with the one or more target receive powers;
• transmitting information indicating an uplink path loss value;
• and
• receiving the data or control transmission, wherein a transmit power of the data or control transmission is based at least in part on at least one of a downlink path loss value associated with the UE, the uplink path loss value, or a combined path loss value, and wherein the transmit power is based at least in part on the configuration information.
