Abstract
Apparatuses, methods, and systems are disclosed for data acknowledgment. One apparatus includes a processor that determines a duration for a downlink (“DL”) burst. The apparatus includes a transmitter that transmits the DL burst having the duration, and signaling indicating a hybrid automatic repeat request acknowledgement (“HARQ-ACK”) codebook size for transmission of HARQ-ACK feedback corresponding to the DL burst.
Claims15
A method of a base station, the method comprising:
- transmitting, to a plurality of user equipments, a first number of physical downlink shared channels contiguously in a time domain without any gap between each physical downlink shared channel of the first number of physical downlink shared channels;
- determining a size of a hybrid automatic repeat request acknowledgement codebook corresponding to the first number of physical downlink shared channels, wherein:
- the size of the hybrid automatic repeat request acknowledgement codebook equals the first number in response to:
- a maximum of one transport block being transmitted in each of the first number of physical downlink shared channels;
- or a maximum of two transport blocks being transmitted in each of the first number of physical downlink shared channels and spatial bundling being configured;
- or
- the size of the hybrid automatic repeat request acknowledgement codebook is double the first number in response to:
- spatial bundling being not configured;
- and
- a maximum of two transport blocks being transmitted in each of the first number of physical downlink shared channels;
- transmitting, to the plurality of user equipments, an indicator indicating the size of the hybrid automatic repeat request acknowledgement codebook;
- and
- receiving, from the plurality of user equipments, the hybrid automatic repeat request acknowledgement codebook based on the indicator.

An apparatus comprising a user equipment, the apparatus further comprising:
- a receiver that:
- receives, from a base station, a second number of physical downlink shared channels, wherein the second number of physical downlink shared channels is included in a first number of physical downlink shared channels and the first number of physical downlink shared channels are contiguously transmitted in a time domain without any gap between each physical downlink shared channel of the first number of physical downlink shared channels;
- and
- receives, from the base station, an indicator indicating a size of a hybrid automatic repeat request acknowledgement codebook corresponding to the first number of physical downlink shared channels;
- a processor that generates the hybrid automatic repeat request acknowledgement codebook based on the indicator, wherein:
- each bit of the hybrid automatic repeat request acknowledgement codebook corresponds to one physical downlink shared channel of the first number of physical downlink shared channels in response to:
- a maximum of one transport block being transmitted in each of the first number of physical downlink shared channels;
- or a maximum of two transport blocks being transmitted in each of the first number of physical downlink shared channels and spatial bundling being configured;
- or
- every two consecutive bits of the hybrid automatic repeat request acknowledgement codebook corresponds to one of the first number of physical downlink shared channels in response to:
- spatial bundling being not configured;
- and
- a maximum of two transport blocks being transmitted in each of the first number of physical downlink shared channels and;
- a transmitter that transmits, to the base station, the hybrid automatic repeat request acknowledgement codebook.
