  • Patent number: 11476980
    Abstract: The present application is related to a method and apparatus for determining a hybrid automatic repeat request-acknowledge (HARQ-ACK) codebook for carrier aggregation (CA). A method for determining a HARQ-ACK codebook for CA includes receiving a first control signal on a carrier within a carrier group in a slot, wherein the first control signal includes an indicator for indicating whether the carrier is a last scheduled carrier of the carrier group for downlink transmissions. The method further includes transmitting a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook corresponding to the downlink transmissions in the slot for the carrier group, wherein, based on the first control signal, one or more HARQ-ACK bits for the last scheduled carrier are arranged at the end of the HARQ-ACK codebook. The present application reduces signaling overhead for a HARQ-ACK codebook and avoids misunderstanding between a base unit and a remote unit when determining the HARQ-ACK codebook for CA.
