Systems and methods for high-reliability ultra-reliable low latency communication transmissions
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.
1. A method by a user equipment (UE), the method comprising:
receiving first downlink control information (DCI) in a first control resource set (CORESET), the first DCI providing first scheduling information for transmission of first data over a first physical downlink shared channel (PDSCH);
receiving second DCI in a second CORESET, the second DCI providing second scheduling information for transmission of second data over a second PDSCH; and
receiving a CORESET configuration, wherein the first and second CORESETs are decoded in a decoding order in which the first and second CORESETs are arranged in the CORESET configuration.
2. The method of claim 1 , 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.
3. The method of claim 1 , wherein the second data is a repetition of the first data.
4. The method of claim 1 , wherein the first CORESET and the second CORESET are received using at least one of:
different time resources;
different frequency resources; and
different beams.
5. The method of claim 1 , wherein, when the second DCI is a repetition of the first DCI, the UE determines that the first PDSCH and the second PDSCH are for ultra-reliable low latency communication (URLLC) data.
6. The method of claim 1 , wherein the second DCI includes an indication that the second data is the same as the first data.
7. The method of claim 1 , wherein, when one of the first DCI and the second DCI is decoded successfully, a decoding failure of the other one of the first DCI and the second DCI does not count as a control channel failure.
8. The method of claim 1 , further comprising:
receiving third DCI in a third CORESET over a third PDCCH, the third DCI providing the first scheduling information for transmission of the first data over the first PDSCH,
wherein the first DCI and the third DCI have at least one of different coding rates and different aggregation levels.
9. The method of claim 2 , wherein the CORESET configuration includes an explicit indication of a decoding order for decoding the first and second CORESETs.
10. 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 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 second scheduling information for transmission of second data over a second PDSCH; and receive a CORESET configuration, wherein the first and second CORESETs are decoded in a decoding order in which the first and second CORESETs are arranged in the CORESET configuration.
11. The UE of claim 10 , 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.
12. The UE of claim 10 , wherein the second data is a repetition of the first data.
13. The UE of claim 10 , wherein the first CORESET and the second CORESET are received using at least one of:
different time resources;
different frequency resources; and
different beams.
14. The UE of claim 10 , wherein, when the second DCI is a repetition of the first DCI, the UE determines that the first PDSCH and the second PDSCH are for ultra-reliable low latency communication (URLLC) data.
15. The UE of claim 10 , wherein the second DCI includes an indication that the second data is the same as the first data.
16. The UE of claim 10 , wherein, when one of the first DCI and the second DCI is decoded successfully, a decoding failure of the other one of the first DCI and the second DCI does not count as a control channel failure.
17. The UE of claim 10 , wherein the at least one processor is further configured to execute the computer-executable instructions to:
receive third DCI in a third CORESET over a third PDCCH, the third DCI providing the first scheduling information for transmission of the first data over the first PDSCH,
wherein the first DCI and the third DCI have at least one of different coding rates and different aggregation levels.
18. The UE of claim 10 , wherein the CORESET configuration includes an explicit indication of a decoding order for decoding the first and second CORESETs.
