Title:
METHODS AND APPARATUSES FOR HARQ-ACK FEEDBACK MULTIPLEXING ON A PUSCH FOR CARRIER AGGREGATION
Document Type and Number:
WIPO Patent Application WO/2024/082350
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to methods and apparatuses for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback multiplexing on a physical uplink shared channel (PUSCH) for carrier aggregation (CA). According to some embodiments of the disclosure, a user equipment (UE) may include: a transceiver configured to receive one or more downlink control information (DCI) formats scheduling a plurality of PUSCHs on a plurality of serving cells of the UE; a processor coupled to the transceiver and configured to: determine that one or more PUSCHs of the plurality of PUSCHs overlap a physical uplink control channel (PUCCH) carrying HARQ-ACK feedback for a downlink transmission; and determine a reference PUSCH among the plurality of PUSCHs for multiplexing the HARQ-ACK feedback; and wherein the transceiver is further configured to transmit the plurality of PUSCHs, wherein the HARQ-ACK feedback is multiplexed on the reference PUSCH.
