Abstract
Methods and apparatuses for retransmitting uplink control information. An apparatus comprising: a receiver that receives uplink control information (UCI) from a remote unit, wherein the UCI includes hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback corresponding to a plurality of downlink transmissions; a processor that decodes the UCI; and a transmitter that, in response to the UCI not being correctly decoded, transmits downlink control information (DCI) including a first signaling to the remote unit, wherein the first signaling includes an indicator indicating that the UCI is not correctly decoded and an identification corresponding to the UCI.
Claims20
A base station, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the base station to:
- transmit, to a user equipment (UE), a set of downlink transmissions;
- receive, from the UE, hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback corresponding to the set of downlink transmissions;
- decode the HARQ-ACK feedback;
- in response to the HARQ-ACK feedback not being correctly decoded, transmit, to the UE, first downlink control information (DCI) including a first indicator for requesting the UE to retransmit the HARQ-ACK feedback;
- and
- in response to the HARQ-ACK feedback being correctly decoded, transmit a second DCI to the UE including a third indicator indicating that the HARQ-ACK feedback is correctly decoded.
A user equipment (UE), comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the UE to:
- receive a set of downlink transmissions;
- transmit hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback corresponding to the set of downlink transmissions;
- receive first downlink control information (DCI);
- retransmit the HARQ-ACK feedback in response to the first DCI including a first indicator for requesting a user equipment (UE) to retransmit the HARQ-ACK feedback;
- and
- receive a second DCI including a third indicator indicating the HARQ-ACK feedback is correctly decoded.
A method performed by a base station, the method comprising:
- transmitting, to a user equipment (UE), a set of downlink transmissions;
- receiving, from the UE, hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback corresponding to the set of downlink transmissions;
- decoding the HARQ-ACK feedback;
- in response to the HARQ-ACK feedback not being correctly decoded, transmitting, to the UE, first downlink control information (DCI) including a first indicator for requesting the UE to retransmit the HARQ-ACK feedback;
- and
- in response to the HARQ-ACK feedback being correctly decoded, transmitting a second DCI to the UE including a third indicator indicating that the HARQ-ACK feedback is correctly decoded.
A method performed by a user equipment (UE), the method comprising:
- receiving a set of downlink transmissions;
- transmitting hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback corresponding to the set of downlink transmissions;
- receive first downlink control information (DCI);
- retransmitting the HARQ-ACK feedback in response to the first DCI including a first indicator for requesting a user equipment (UE) to retransmit the HARQ-ACK feedback;
- and
- receiving a second DCI including a third indicator indicating the HARQ-ACK feedback is correctly decoded.
