Abstract  Abstract

PROBLEM TO BE SOLVED: To guarantee that N ACKs/NAKs can be arranged correctly.

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