Abstract  Abstract

PROBLEM TO BE SOLVED: To guarantee that a number N (N is greater than 1) of acknowledgements (ACKs)/negative acknowledgements (NAKs) are arrayed properly.

SOLUTION: The invention relates to radio communications and discloses a method and apparatus for feeding back and receiving ACK information of semi-persistent scheduling (SPS) data packets. The method includes: receiving downlink data packets and an uplink data assignment indicator (UL DAI) from a base station (BS) wherein a value of the UL DAI indicates the number N of downlink data packets transmitted by the BS and a number (k) (k<N) of downlink data packets are SPS data packets; forming a feedback signal comprising N ACKs/NAKs acknowledging the N downlink data packets (k) ACKs/NAKs of the (k) SPS data packets is/are placed from (N-k+1)th to Nth positions of the N ACKs/NAKs; and sending the feedback signal starting from the ACK/NAK at the first position to the BS.
