Abstract
A method of wireless communication by a user equipment (UE) includes transmitting, to a network node, a first stage hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook on an orthogonal multiple access (OMA) resource. The method also includes transmitting, to the network node, a second stage HARQ-ACK codebook on a non-orthogonal multiple access (NOMA) resource in response to the first stage HARQ-ACK codebook indicating at least one negative acknowledgement (NACK).
Claims28
A method of wireless communication by a user equipment (UE), comprising:
- transmitting, to a network node, a first stage hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook on an orthogonal multiple access (OMA) resource;
- and
- transmitting, to the network node, a second stage HARQ-ACK codebook on a non-orthogonal multiple access (NOMA) resource in response to the first stage HARQ-ACK codebook indicating at least one negative acknowledgement (NACK).
A method of wireless communication by a network device, comprising:
- receiving, from a user equipment (UE), a first stage hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook on an orthogonal multiple access (OMA) resource;
- and
- receiving, from the UE, a second stage HARQ-ACK codebook on a non-orthogonal multiple access (NOMA) resource in response to the first stage HARQ-ACK codebook indicating at least one negative acknowledgment (NACK).
An apparatus for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory, the at least one processor configured:
- to transmit, to a network node, a first stage hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook on an orthogonal multiple access (OMA) resource;
- and
- to transmit, to the network node, a second stage HARQ-ACK codebook on a non-orthogonal multiple access (NOMA) resource in response to the first stage HARQ-ACK codebook indicating at least one negative acknowledgement (NACK).
