Abstract
The application relates to radio communication technologies and discloses a method for receiving semi-persistent scheduling (SPS) data packets and sending acknowledgment information of the SPS data packets. A communication apparatus receives physical downlink shared channel (PDSCH) data packets from a base station. The PDSCH data packets include one or more dynamic scheduling data packets and one or more semi-persistent scheduling (SPS) data packets. The communication apparatus sends, to the base station, a sequence including feedback information of the PDSCH data packets. The sequence includes a plurality of bits. Each bit carries an acknowledgement (ACK) or a negative acknowledgement (NAK) to one PDSCH data packet respectively. The bits carrying acknowledgements of the one or more SPS data packets are arranged at the end of the sequence.

9. The communication apparatus according to claim 8, wherein one data packet is carried in one subframe.
10. The communication apparatus according to claim 9, wherein the program instructions further cause the communication apparatus to:
obtain an uplink data assignment indicator (UL DAI) from the base station, wherein the UL DAI indicates quantity of the PDSCH subframes.
11. The communication apparatus according to claim 9, wherein the program instructions further cause the communication apparatus to:
obtain a downlink data assignment indicator (DL DAI) from the base station, wherein the DL DAT indicates a serial number of a PDSCH subframe in a current transmission period.
12. The communication apparatus according to claim 8, wherein the one or more SPS data packets is one SPS data packet.
13. The communication apparatus according to claim 12, wherein the ACK or NAK of the SPS data packet is placed at the last bit of the sequence regardless of a transmission order of the PDSCH data packets.
14. The communication apparatus according to claim 8, wherein each of the one or more dynamic scheduling data packets is a PDSCH data packet associated with a physical downlink control channel (PDCCH), and each of the one or more SPS data packets is a PDSCH data packet not associated with a PDCCH.
15. The communication apparatus according to claim 8, wherein the communication apparatus is a component of a user equipment device.
16. The communication apparatus according to claim 8, wherein the communication apparatus is a user equipment device
17. A non-transitory storage medium storing program instructions, wherein when executed by a processor of a communication apparatus, the program instructions cause the communication apparatus to perform a method that comprises:
receiving physical downlink shared channel (PDSCH) data packets from a base station, wherein the PDSCH data packets comprise one or more dynamic scheduling data packets and one or more semi-persistent scheduling (SPS) data packets; and sending to the base station, a sequence comprising feedback information of the PDSCH data packets, wherein the sequence comprises a plurality of bits, each bit carries an acknowledgement (ACK) or a negative acknowledgement (NAK) to one PDSCH data packet respectively, and wherein the bits carrying the ACKs/NAKs of the one or more SPS data packets are arranged at the end of the sequence.
18. The non-transitory storage medium according to claim 17, wherein one data packet is carried in one subframe.
19. The non-transitory storage medium according to claim 17, wherein the one or more SPS data packets is one SPS data packet.
20. The non-transitory storage medium according to claim 19, wherein the ACK or NAK of the SPS data packet is placed at the last bit of the sequence regardless of a transmission order of the PDSCH data packets.
21. The non-transitory storage medium according to claim 17, wherein each of the one or more dynamic scheduling data packets is a PDSCH data packet associated with a physical downlink control channel (PDCCH), and each of the one or more SPS data packets is a PDSCH data packet not associated with a PDCCH.
