摘要：
A method and apparatus for feeding back and receiving acknowledgment (ACK) information of semi-persistent scheduling (SPS) data packets are disclosed. 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), wherein the UL DAI indicates a number (N) of downlink data packets, mapping acknowledgements/negative acknowledgements (ACKs/NAKs) of k SPS data packets of the downlink data packets to positions from the (N−k+1)th ACK/NAK to the Nth ACK/NAK, and feeding back N ACKs/NAKs to the BS.
