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 wherein a value of the UL DAI indicates a number (N) of all scheduled downlink sub-frames which scheduled by the base station for the user equipment 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 base station starting from the ACK/NAK at the first position.

a transmitter, configured to send the feedback signal to the base station.
6. The user equipment according to claim 5, wherein an SPS sub-frame is a sub-frame that carries a data packet without a resource scheduling index, and a dynamic scheduling sub-frame is a sub-frame that carries a data packet with a resource scheduling index.
7. The user equipment according to claim 5, wherein the N scheduled PDSCH sub-frames include one SPS sub-frame, and the ACK/NAK in response to the SPS sub-frame is placed in the feedback signal at the last position of the N ACKs/NAKs.
8. The user equipment according to claim 5, wherein the receiver is configured to receive an uplink data assignment indicator (UL DAI) and the N PDSCH sub-frames from the base station, wherein the UL DAI indicates the quantity N of the scheduled PDSCH sub-frames.
9. A computer program product comprising a non-transitory storage medium having stored thereon a computer program for use by a user equipment, wherein the program comprises:
instructions for obtaining a quantity N of physical downlink shared channel (PDSCH) sub-frames that are scheduled by a base station for the user equipment, the N scheduled PDSCH sub-frames including at least one semi-persistent scheduling (SPS) sub-frame and at least one dynamic scheduling sub-frame;
instructions for forming a feedback signal comprising N acknowledgements/negative acknowledgements (ACKs/NAKs) in response to the N PDSCH sub-frames scheduled for the user equipment, wherein the feedback signal comprises at least one ACK/NAK in response to the at least one SPS sub-frame and at least one ACK/NAK in response to the at least one dynamic scheduling sub-frame, and wherein the at least one ACK/NAK in response to the at least one SPS sub-frame follows after behind the ACK/NAK in response to the at least one dynamic scheduling sub-frame; and
instructions for sending the feedback signal to the base station.
10. The computer program product according to claim 9, wherein the N scheduled PDSCH sub-frames include one SPS sub-frame, and the ACK/NAK in response to the SPS sub-frame is placed in the feedback signal at the last position of the N ACKs/NAKs.
