Abstract

A wireless device receives, via at least one of one or more first monitoring occasions, a first downlink control information (DCI) scheduling an uplink shared channel transmission. The wireless device receives, via a second monitoring occasion of second monitoring occasions, a repetition of a second DCI indicating transmission of an acknowledgement feedback. The wireless device sets the acknowledgement feedback to a negative acknowledgement (NACK) value based on a start of the second monitoring occasions being after a start of the one or more first monitoring occasions. The wireless device transmits, in the uplink shared channel transmission, the acknowledgement feedback.

Claims (35)

1. A wireless device comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the wireless device to:

receive, via at least one of one or more first monitoring occasions, a first downlink control information (DCI) scheduling an uplink shared channel transmission;

receive, via a second monitoring occasion of second monitoring occasions, a repetition of a second DCI indicating transmission of an acknowledgement feedback for a physical downlink shared channel (PDSCH) reception;

based on a start of the second monitoring occasions being after a start of the one or more first monitoring occasions, set the acknowledgement feedback to a negative acknowledgement (NACK) value; and

transmit the acknowledgement feedback multiplexed in the uplink shared channel transmission.

2. The wireless device of claim 1 , wherein the second monitoring occasion is one or more second monitoring occasions of the second monitoring occasions.

3. The wireless device of claim 1 , wherein the acknowledgement feedback is transmitted in an acknowledgement codebook.

4. The wireless device of claim 3 , wherein the acknowledgement codebook is a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook.

5. The wireless device of claim 1 , wherein the acknowledgement feedback is a hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback.

6. The wireless device of claim 1 , wherein the second DCI schedules the PDSCH reception.

7. The wireless device of claim 1 , wherein the second DCI indicates a semi-persistent scheduling (SPS) PDSCH release.

8. The wireless device of claim 1 , wherein the instructions further cause the wireless device to transmit the acknowledgement feedback multiplexed into the uplink shared channel transmission.

9. A base station comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the base station to:

transmit, via at least one of one or more first monitoring occasions, a first downlink control information (DCI) scheduling an uplink shared channel transmission;

transmit, via a second monitoring occasion of second monitoring occasions, a repetition of a second DCI indicating transmission of an acknowledgement feedback for a physical downlink shared channel (PDSCH) reception; and

based on a start of the second monitoring occasions being after a start of the one or more first monitoring occasions, receive the acknowledgement feedback multiplexed in the uplink shared channel transmission, wherein the acknowledgement feedback is set to a negative acknowledgement (NACK) value.

10. The base station of claim 9 , wherein the second monitoring occasion is one or more second monitoring occasions of the second monitoring occasions.

11. The base station of claim 9 , wherein the acknowledgement feedback is transmitted in an acknowledgement codebook.

12. The base station of claim 11 , wherein the acknowledgement codebook is a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook.

13. The base station of claim 9 , wherein the acknowledgement feedback is a hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback.

14. The base station of claim 9 , wherein the second DCI schedules the PDSCH reception.

15. The base station of claim 9 , wherein the second DCI indicates a semi-persistent scheduling (SPS) PDSCH release.

16. The base station of claim 9 , wherein the acknowledgement feedback is multiplexed into the uplink shared channel transmission.

17. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:

receive, via at least one of one or more first monitoring occasions, a first downlink control information (DCI) scheduling an uplink shared channel transmission;

receive, via a second monitoring occasion of second monitoring occasions, a repetition of a second DCI indicating transmission of an acknowledgement feedback for a physical downlink shared channel (PDSCH) reception;

based on a start of the second monitoring occasions being after a start of the one or more first monitoring occasions, set the acknowledgement feedback to a negative acknowledgement (NACK) value; and

transmit the acknowledgement feedback multiplexed in the uplink shared channel transmission.

18. The non-transitory computer-readable medium of claim 17 , wherein the second monitoring occasion is one or more second monitoring occasions of the second monitoring occasions.

19. The non-transitory computer-readable medium of claim 17 , wherein the acknowledgement feedback is transmitted in an acknowledgement codebook.

20. The non-transitory computer-readable medium of claim 17 , wherein the acknowledgement feedback is a hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback.
