Abstract  Abstract

The application relates to radio communications and discloses a method and 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 value of the UL DAI indicates a number (N) of all scheduled downlink sub-frames which scheduled by the BS for the UE the number N is greater than 1 and a number k (k<N) of the downlink data packets is/are semi-persistent scheduling (SPS) data packets; forming a feedback signal comprising N acknowledgements/negative acknowledgements (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 to the BS starting from the ACK/NAK at the first position.
