HARQ feedback collision in unlicensed bands

1. A method comprising:

receiving, by a wireless device, a first downlink control information (DCI) indicating a first slot for transmission of uplink control information (UCI) comprising hybrid automatic repeat request (HARQ) feedback information;

receiving a second DCI scheduling a plurality of physical uplink shared channels (PUSCHs) in a plurality of consecutive slots comprising the first slot;

multiplexing the UCI in a first PUSCH, of the plurality of PUSCHs, in the first slot;

in response to a failed listen-before-talk (LBT) procedure for the first slot, determining a second slot associated with a second PUSCH of the plurality of PUSCHs; and

transmitting, in response to a successful LBT procedure for the second slot, the UCI via the second PUSCH.

2. The method of claim 1 , further comprising performing a first LBT procedure for the first slot for transmission of the first PUSCH, wherein the first LBT procedure indicates a busy channel and the first PUSCH is not transmitted.

3. The method of claim 1 , further comprising multiplexing the UCI in the second PUSCH.

4. The method of claim 1 , wherein a first beta-offset value associated with the first PUSCH is equal to a second beta-offset value associated with the second PUSCH.

5. The method of claim 1 , wherein a first transport block size (TBS) associated with the first PUSCH is equal to a second TBS associated with the second PUSCH.

6. The method of claim 5 , wherein a first new data indicator (NDI) value and a first redundancy version (RV) associated with the first PUSCH are equal to a second NDI value and a second RV associated with the second PUSCH, respectively.

7. The method of claim 1 , further comprising multiplexing a first transport block (TB) in the first PUSCH, and multiplexing the UCI and a second TB in the second PUSCH.

8. The method of claim 7 , wherein the second TB is the first TB.

9. The method of claim 7 , further comprising, in response to the failed LBT procedure for the first slot, transmitting the first TB via a third PUSCH from the plurality of PUSCHs, that is different than the second PUSCH.

10. The method of claim 1 , wherein the second PUSCH is a next PUSCH, among the plurality of PUSCHs, immediately after the first PUSCH.

11. 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 a first downlink control information (DCI) indicating a first slot for transmission of uplink control information (UCI) comprising hybrid automatic repeat request (HARQ) feedback information;

receive a second DCI scheduling a plurality of physical uplink shared channels (PUSCHs) in a plurality of consecutive slots comprising the first slot;

multiplex the UCI in a first PUSCH, of the plurality of PUSCHs, in the first slot;

in response to a failed listen-before-talk (LBT) procedure for the first slot, determine a second slot associated with a second PUSCH of the plurality of PUSCHs; and

transmit, in response to a successful LBT procedure for the second slot, the UCI via the second PUSCH.

12. The wireless device of claim 11 , wherein the instructions further cause the wireless device to perform a first LBT procedure for the first slot for transmission of the first PUSCH, wherein the first LBT procedure indicates a busy channel and the first PUSCH is not transmitted.

13. The wireless device of claim 11 , wherein the instructions further cause the wireless device to multiplex the UCI in the second PUSCH.

14. The wireless device of claim 11 , wherein a first beta-offset value associated with the first PUSCH is equal to a second beta-offset value associated with the second PUSCH.

15. The wireless device of claim 11 , wherein a first transport block size (TBS) associated with the first PUSCH is equal to a second TBS associated with the second PUSCH.

16. The wireless device of claim 15 , wherein a first new data indicator (NDI) value and a first redundancy version (RV) associated with the first PUSCH are equal to a second NDI value and a second RV associated with the second PUSCH, respectively.

17. The wireless device of claim 11 , wherein the instructions further cause the wireless device to multiplex a first transport block (TB) in the first PUSCH, and multiplexing the UCI and a second TB in the second PUSCH.

18. The wireless device of claim 17 , wherein the second TB is the first TB.

19. The wireless device of claim 11 , wherein the instructions further cause the wireless device to transmit, in response to the failed LBT procedure for the first slot, the first TB via a third PUSCH from the plurality of PUSCHs, that is different than the second PUSCH.

20. A system comprising:

a base station; and

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, from the base station, a first downlink control information (DCI) indicating a first slot for transmission of uplink control information (UCI) comprising hybrid automatic repeat request (HARQ) feedback information;

receive, from the base station, a second DCI scheduling a plurality of physical uplink shared channels (PUSCHs) in a plurality of consecutive slots comprising the first slot;

multiplex the UCI in a first PUSCH, of the plurality of PUSCHs, in the first slot;

in response to a failed listen-before-talk (LBT) procedure for the first slot, determine a second slot associated with a second PUSCH of the plurality of PUSCHs; and

transmit, to the base station and in response to a successful LBT procedure for the second slot, the UCI via the second PUSCH.
