Method and Apparatus for Feeding Back and Receiving Acknowledgement Information of Semi-Persistent Scheduling Data Packets

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) 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 N th ACK/NAK and feeding back N ACKs/NAKs to the BS.

2. The method of claim 1, wherein mapping the ACKs/NAKs comprises mapping the ACKs/NAKs of k SPS data packets of the downlink data packets to the positions from the (Nâx88x92k+1)th ACK/NAK to the Nth ACK/NAK in positive or negative sequence.

3. The method of claim 1, further comprising mapping ACKs/NAKs of non-SPS data packets of the downlink data packets to positions from a first ACK/NAK among the N ACKs/NAKs.

4. The method of claim 3, wherein mapping the ACKs/NAKs of the non-SPS data packets comprises:
receiving a Downlink Assignment Index (DL DAI) from the BS, wherein the DL DAI indicates that a downlink data packet is an Mth non-SPS data packet of the downlink data packets; and
mapping an ACK/NAK of the Mth non-SPS data packet at a position of the Mth ACK/NAK.', 'receiving a Downlink Assignment Index (DL DAI) from the BS, wherein the DL DAI indicates that a downlink data packet is an Mth non-SPS data packet of the downlink data packets; and', 'mapping an ACK/NAK of the Mth non-SPS data packet at a position of the Mth ACK/NAK.

5. The method of claim 4, wherein the SPS data packets comprise data packets without a resource scheduling index and the non-SPS data packets comprise data packets with a resource scheduling index.

6. The method of claim 3, wherein the SPS data packets comprise data packets without a resource scheduling index and the non-SPS data packets comprise data packets with a resource scheduling index.

7. A method for receiving acknowledgement (ACK) information of semi-persistent scheduling (SPS) data packets, the method comprising:
sending an uplink downlink assignment index (UL DAI) to a User Equipment (UE) wherein the UL DAI indicates a number (N) of downlink data packets; and
receiving N acknowledgements/negative acknowledgements (ACKs/NAKs) feedback sent by the UE, wherein positions from the (Nâx88x92k+1)th ACK/NAK to the Nth ACK/NAK are used for mapping ACKs/NAKs of k SPS data packets of the downlink data packets, where k is a positive integer.', 'sending an uplink downlink assignment index (UL DAI) to a User Equipment (UE) wherein the UL DAI indicates a number (N) of downlink data packets; and', 'receiving N acknowledgements/negative acknowledgements (ACKs/NAKs) feedback sent by the UE, wherein positions from the (Nâx88x92k+1)th ACK/NAK to the Nth ACK/NAK are used for mapping ACKs/NAKs of k SPS data packets of the downlink data packets, where k is a positive integer.

8. The method of claim 7, further comprising transmitting an SPS activation signaling at a next time of semi-persistent transmission or at a time of SPS retransmission in response to receiving a NAK feedback to an SPS activation sub-frame.

9. The method of claim 7, wherein a first position of N ACKs/NAKs is used for mapping k SPS data packets of the downlink data packets such that ACKs/NAKs of non-SPS data packets of the downlink data packets are mapped to positions from a first ACK/NAK among N ACKs/NAKs

10. The method of claim 9, wherein mapping the ACKs/NAKs of the non-SPS data packets comprises:
sending a downlink assignment index (DL DAI) to the UE, wherein the DL DAI indicates that a downlink data packet is an Mth non-SPS data packet of the downlink data packets; and
receiving M ACKs/NAKs, wherein the Mth non-SPS data packet is mapped at a position of the Mth ACK/NAK.', 'sending a downlink assignment index (DL DAI) to the UE, wherein the DL DAI indicates that a downlink data packet is an Mth non-SPS data packet of the downlink data packets; and', 'receiving M ACKs/NAKs, wherein the Mth non-SPS data packet is mapped at a position of the Mth ACK/NAK

11. The method of claim 7, wherein the positions from the (Nâx88x92k+1)th ACK/NAK to the Nth ACK/NAK are used for mapping the ACKs/NAKs of k SPS data packets of the downlink data packets such that the ACKs/NAKs of k SPS data packets of the downlink data packets are mapped at positions from the (Nâx88x92k+1)th ACK/NAK to the Nth ACK/NAK in positive or negative sequence

a processing unit adapted to map acknowledgements/negative acknowledgements (ACKs/NAKs) of k SPS data packets of the downlink data packets to positions from an (Nâx88x92k+1)th ACK/NAK to an Nth ACK/NAK, where k is a positive integer; and
a feedback unit adapted to feed back N ACKs/NAKs to the BS.', 'a receiving unit adapted to receive an uplink downlink assignment index (UL DAI) from a base station (BS), wherein the UL DAI indicates a number (N) of downlink data packets;', 'a processing unit adapted to map acknowledgements/negative acknowledgements (ACKs/NAKs) of k SPS data packets of the downlink data packets to positions from an (Nâx88x92k+1)th ACK/NAK to an Nth ACK/NAK, where k is a positive integer; and', 'a feedback unit adapted to feed back N ACKs/NAKs to the BS

16. The apparatus of claim 15, wherein the processing unit is further adapted to map ACKs/NAKs of non-SPS data packets of the downlink data packets to positions from a first ACK/NAK among N ACKs/NAKs.']
