Method and apparatus for allocating and signaling ack/nack resources in a wireless communication system

A user equipment in a wireless communication system, the user equipment comprising:

• a transceiver;
• and
• a controller configured to:
• receive, from a base station, via the transceiver, data on a downlink data channel;
• determine whether a scheduling type of the downlink data channel is persistent or non-persistent;
• and
• transmit, to the base station, via the transceiver, acknowledgement/negative acknowledgement (Ack/Nack) information for the data,
• wherein, in case that the scheduling type is non-persistent, the Ack/Nack information for the data is transmitted on a resource which is one of pre-configured resources, and
• wherein, in case that the scheduling type is persistent, the Ack/Nack information for an initial persistent data transmission is transmitted on a resource which is one of the pre-configured resources, and the Ack/Nack information for a following persistent data transmission is transmitted on a resource indicated by resource indication information via high-layer signaling.

A method performed by a base station in a wireless communication system, the method comprising:

• determining a scheduling type of a downlink data channel as persistent or non-persistent;
• transmitting, to a user equipment, data on the downlink data channel based on the determination;
• and
• receiving, from the user equipment, acknowledgement/negative acknowledgement (Ack/Nack) information for the data,
• wherein, in case that the scheduling type is non-persistent, the Ack/Nack information for the data is received on a resource which is one of pre-configured resources, and
• wherein, in case that the scheduling type is persistent, the Ack/Nack information for an initial persistent data transmission is received on a resource which is one of the pre-configured resources, and the Ack/Nack information for a following persistent data transmission is received on a resource indicated by resource indication information via high-layer signaling.
