Abstract
Apparatuses, methods, and systems are disclosed for triggering HARQ-ACK feedback for a downlink slot set. One apparatus includes a receiver that receives a first control signal from a base unit for triggering HARQ-ACK feedback for a downlink slot set. The downlink slot set comprises multiple downlink slots. The apparatus includes a processor that identifies the downlink slot set in response to the first control signal and a transmitter that transmits UCI to the base unit in a slot determined by the first control signal. Here, the UCI comprises the HARQ-ACK feedback for the identified downlink slot set. The HARQ-ACK feedback for the downlink slot set corresponds to all downlink transmissions in the downlink slot set and is transmitted in one UCI.
Claims18
An apparatus comprising:
- a receiver that receives a first control signal from a base unit for triggering hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback for a downlink slot set, wherein the downlink slot set comprises multiple downlink slots and the HARQ-ACK feedback for the downlink slot set corresponds to all downlink transmissions in the downlink slot set and is transmitted in one uplink control information (UCI) and the first control signal indicates one or more of:
- a starting slot index for the downlink slot set, an ending slot index for the downlink slot set, and a number of slots of the downlink slot set;
- a processor that identifies the downlink slot set in response to the first control signal using the indication received in the first control signal;
- and
- a transmitter that transmits UCI to the base unit in a slot determined by the first control signal, wherein the UCI comprises the HARQ-ACK feedback for the identified downlink slot set.
A method comprising:
- receiving a first control signal from a base unit for triggering hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback for a downlink slot set, wherein the downlink slot set comprises multiple downlink slots and the HARQ-ACK feedback for the downlink slot set corresponds to all downlink transmissions in the downlink slot set and is transmitted in one uplink control information (UCI) and the first control signal indicates one or more of:
- a starting slot index for the downlink slot set, an ending slot index for the downlink slot set, and a number of slots of the downlink slot set;
- identifying the downlink slot set in response to the first control signal using the indication received in the first control signal;
- and
- transmitting UCI to the base unit in a slot determined by the first control signal, wherein the UCI comprises the HARQ-ACK feedback for the identified downlink slot set.
