Abstract  Abstract

The present invention 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 for feeding back ACK information of SPS data packets includes: receiving an uplink downlink assignment index (UL DAI) from a base station (BS) where the value of the UL DAI indicates the number of downlink data packets (N); mapping ACKs/NAKs of k SPS data packets of the downlink data packets to positions from the (N?k+1)th ACK/NAK to the N th ACK/NAK; and feeding back N ACKs/NAKs to the BS. This method can guarantee that N ACKs/NAKs are arranged correctly.
