Abstract

A method for wireless communication involving high-reliability ultra-reliable low latency communication (URLLC) control and data channel transmissions is disclosed. The method includes receiving, by a user equipment (UE), first downlink control information (DCI) in a first control resource set (CORESET), the first DCI providing scheduling information for transmission of first data over a first physical downlink shared channel (PDSCH), receiving, by the UE, second DCI in a second CORESET, the second DCI providing scheduling information for transmission of second data over a second PDSCH. The method also includes receiving, by the UE, the first data over the first PDSCH, and receiving, by the UE, the second data over the second PDSCH, where the first data and the second data are repetition data.

Claims (67)

1. A method comprising:

receiving, by a user equipment (UE), first downlink control information (DCI) in a first control resource set (CORESET), the first DCI providing a first scheduling information for transmission of first data over a first physical downlink shared channel (PDSCH);

receiving, by the UE, second DCI in a second CORESET, the second DCI providing a second scheduling information for transmission of second data, which is the same as the first data, over a second PDSCH; and

receiving, by the UE, the first data over the first PDSCH and the second data over the second PDSCH using, respectively, the first and second scheduling information, wherein the first and second CORESETs are received using at least one of different time resources, different frequency resources, and different beams.

2. The method of claim 1 , wherein receiving the first DCI comprises receiving the first DCI over a first physical downlink control channel (PDCCH), and wherein receiving the second DCI comprises receiving the second DCI over a second PDCCH.

3. The method of claim 1 , wherein the first CORESET and the second CORESET each includes a decoding order for decoding the respective first DCI and second DCI.

4. The method of claim 1 , wherein the UE refers to at least one of a time reference signal or a frequency reference signal associated with the second data to decode the first data.

5. The method of claim 1 , further comprising soft combining the first data and the second data by the UE.

6. The method of claim 1 , further comprising:

ignoring, by the UE, the second DCI; and

decoding, by the UE, the second data over the second PDSCH using the first DCI.

7. The method of claim 1 , wherein:

the first DCI includes at least one of: a first redundancy version information element, a first new data indicator information element, a first hybrid automatic repeat request (HARQ) process number, and a first new data indicator (NDI);

the second DCI includes at least one of: a second redundancy version information element, a second new data indicator information element, a second HARQ process number, and a second NDI; and

wherein at least one of:

the first and second redundancy version information elements are the same;

the first and second new data indicator information elements are the same;

the first and second HARQ process number are the same; and

the first and second NDIs are the same.

8. The method of claim 1 , further comprising:

receiving, by the UE, third DCI in a third CORESET, the third DCI providing scheduling information for transmission of the first data over the first PDSCH.

9. The method of claim 8 , wherein receiving the third DCI comprises receiving the third DCI over a third PDCCH.

10. The method of claim 9 , wherein at least one of:

the first PDCCH and the second PDCCH are repetition PDCCHs;

the first PDCCH and the third PDCCH are repetition PDCCHs; and

the second PDCCH and the third PDCCH are repetition PDCCHs.

11. The method of claim 8 , wherein the first DCI and the third DCI have at least one of different coding rates and different aggregation levels.

12. The method of claim 8 , further comprising:

soft combining, by the UE, the first DCI and the third DCI to form a combined DCI for obtaining the first scheduling information for transmission of the first data.

13. The method of claim 8 , further comprising:

ignoring, by the UE, the first DCI; and

decoding, by the UE, the first data over the first PDSCH using the third DCI.

14. A user equipment (UE) comprising:

one or more non-transitory computer-readable media having computer-executable instructions embodied thereon;

at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to:

receive first downlink control information (DCI) in a first control resource set (CORESET), the first DCI providing a first scheduling information for transmission of first data over a first physical downlink shared channel (PDSCH);

receive second DCI in a second CORESET, the second DCI providing a second scheduling information for transmission of second data, which is the same as the first data, over a second PDSCH; and

receive the first data over the first PDSCH and the second data over the second PDSCH using, respectively, the first and second scheduling information, wherein the first and second

CORESETs are received using at least one of different time resources, different frequency resources, and different beams.

15. The UE of claim 14 , wherein the first DCI is received by the UE over a first physical downlink control channel (PDCCH), and the second DCI is received by the UE over a second PDCCH.

16. The UE of claim 14 , wherein the first CORESET and the second CORESET each includes a decoding order for decoding the respective first DCI and second DCI.

17. The UE of claim 14 , wherein the UE refers to at least one of a time reference signal or a frequency reference signal associated with the second data to decode the first data.

18. The UE of claim 14 , wherein the first data is encoded using a first modulation scheme based on the first DCI, and the second data is encoded using a second modulation scheme based on the second DCI.

19. The UE of claim 14 , wherein the at least one processor is further configured to execute the computer-executable instructions to:

ignore the second DCI; and

decode the second data over the second PDSCH using the first DCI.

20. The UE of claim 14 , wherein:

the first DCI includes at least one of: a first redundancy version information element, a first new data indicator information element, a first hybrid automatic repeat request (HARQ) process number, and first new data indicator (NDI);

the second DCI includes at least one of: a second redundancy version information element, a second new data indicator information element, a second HARQ process number, and a second NDI; and

wherein at least one of:

the first and second redundancy version information elements are the same;

the first and second new data indicator information elements are the same;

the first and second HARQ process number are the same; and

the first and second NDIs are the same.

21. The UE of claim 14 , wherein the at least one processor is further configured to execute the computer-executable instructions to:

receive third DCI in a third CORESET, the third DCI providing scheduling information for transmission of the first data over the first PDSCH.

22. The UE of claim 21 , wherein the third DCI is received by the UE over a third PDCCH.

23. The UE of claim 22 , wherein at least one of:

the first PDCCH and the second PDCCH are repetition PDCCHs;

the first PDCCH and the third PDCCH are repetition PDCCHs; and

the second PDCCH and the third PDCCH are repetition PDCCHs.

24. The UE of claim 21 , wherein the first DCI and the third DCI have at least one of different coding rates and different aggregation levels.

25. The UE of claim 21 , wherein the at least one processor is further configured to execute the computer-executable instructions to:
