Abstract:
Methods and devices are provided for transmitting and receiving hybrid automatic repeat request acknowledgement (HARQ-ACK) information in a wireless communication system. Higher layer signaling is received that includes at least one of information indicating whether to apply HARQ-ACK spatial bundling to HARQ-ACK information to be transmitted on a physical uplink control channel (PUCCH) or information indicating whether to apply HARQ-ACK spatial bundling to HARQ-ACK information to be transmitted on a physical uplink shared channel (PUSCH). At least one HARQ-ACK information bit corresponding to downlink data received in at least one cell, is determined based on the higher layer signaling. HARQ-ACK information corresponding to the determined at least one HARQ-ACK information bit is transmitted on at least one of the PUCCH or the PUSCH.
