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, when the scheduling type is non-persistent, the ACK/NACK information is transmitted on a first resource determined according to a downlink control channel corresponding to the data, and
• wherein, when the scheduling type is persistent, the ACK/NACK information for an initial persistent data transmission is transmitted on a second resource determined according to the downlink control channel, and the ACK/NACK information for a following persistent data transmission is transmitted on a third resource determined by using resource information received 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 either 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, acknowledgment/negative acknowledgment (ACK/NACK) information for the data,
• wherein, when the scheduling type is non-persistent, the ACK/NACK information is received on a first a resource determined according to a downlink control channel, and
• wherein, when the scheduling type is persistent, the ACK/NACK information for an initial persistent data transmission is received on a second resource determined according to the downlink control channel, and the ACK/NACK information for a following persistent data transmission is received on a third resource determined by using resource information transmitted via-a high-layer signaling.
