Abstract
Embodiments of the present disclosure relate to methods and apparatuses for HARQ-ACK feedback generation. A UE may: receive signaling for configuring a first set of serving cells, which is co-schedulable by a DCI; receive the DCI scheduling a second set of serving cells in the first set of serving cells and indicating a TCI state different from a previously indicated TCI state; generate a HARQ-ACK codebook for the DCI; transmit the HARQ-ACK codebook; and apply the TCI state in response to the HARQ-ACK codebook including at least one ACK bit.
Claims21
A user equipment (UE) for wireless communication, 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 configuration for a first set of serving cells, which is co-schedulable by a downlink control information (DCI);
- receive the DCI scheduling a second set of serving cells in the first set of serving cells and indicating a transmission configuration indication (TCI) state different from a previously indicated TCI state;
- generate a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook for the DCI;
- transmit the HARQ-ACK codebook;
- and
- apply the TCI state in response to the HARQ-ACK codebook comprising at least one acknowledgement (ACK) bit.
A base station (BS) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the BS to:
- transmit, to a user equipment (UE), a configuration for a first set of serving cells, which is co-schedulable by a downlink control information (DCI);
- transmit, to the UE, the DCI scheduling a second set of serving cells in the first set of serving cells and indicating a transmission configuration indication (TCI) state different from a previously TCI state indicated to the UE;
- receive, from the UE, a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook for the DCI;
- and
- apply the TCI state in response to the HARQ-ACK codebook comprising at least one acknowledgement (ACK) bit.
(canceled)
A method performed by a user equipment (UE), the method comprising:
- receiving signaling for configuring a first set of serving cells, which is co-schedulable by a downlink control information (DCI);
- receiving the DCI scheduling a second set of serving cells in the first set of serving cells and indicating a transmission configuration indication (TCI) state different from a previously indicated TCI state;
- generating a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook for the DCI;
- transmitting the HARQ-ACK codebook;
- and
- applying the TCI state in response to the HARQ-ACK codebook comprising at least one acknowledgement (ACK) bit.
A method performed by a base station (BS), the method comprising:
- transmitting, to a user equipment (UE), a configuration for a first set of serving cells, which is co-schedulable by a downlink control information (DCI);
- transmitting, to the UE, the DCI scheduling a second set of serving cells in the first set of serving cells and indicating a transmission configuration indication (TCI) state different from a previously TCI state indicated to the UE;
- receiving, from the UE, a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook for the DCI;
- and
- applying the TCI state in response to the HARQ-ACK codebook comprising at least one acknowledgement (ACK) bit.
