Abstract

A wireless device receives radio resource control (RRC) messages comprising configuration parameters comprising: a first physical downlink shared channel (PDSCH) time domain allocation list associated with a first downlink control information (DCI) format for scheduling a PDSCH in a slot; and a second PDSCH time domain allocation list associated with a second DCI format for scheduling multiple PDSCHs in multiple slots. The wireless device receives a first DCI with the second DCI format indicating a first entry of the second PDSCH time domain allocation list, and receives transport blocks (TBs), in first slots and via PDSCH resources, determined based on the first entry, wherein each of the TBs is associated with a respective hybrid automatic repeat request process.

First claim

What is claimed is:

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 radio resource control (RRC) messages comprising configuration parameters comprising:
a first physical downlink shared channel (PDSCH) time domain allocation list associated with a first downlink control information (DCI) format for scheduling a PDSCH in a slot; and
a second PDSCH time domain allocation list associated with a second DCI format for scheduling multiple PDSCHs in multiple slots, wherein each entry of the second PDSCH time domain allocation list indicates the multiple slots for the multiple PDSCHs;

receive a first DCI with the second DCI format indicating a first entry of the second PDSCH time domain allocation list; and
receive transport blocks (TBs), in first slots and via PDSCH resources, determined based on the first entry, wherein each of the TBs is associated with a respective hybrid automatic repeat request process.

2. The wireless device of claim 1 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to monitor a first search space for receiving the first DCI with the second DCI format, wherein a first monitoring periodicity of the first search space is greater than a second monitoring periodicity of a second search space for receiving a second DCI with the first DCI format.

3. The wireless device of claim 2 , wherein the first search space is a wireless device specific search space and the second search space is a common search space.

4. The wireless device of claim 2 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive, based on monitoring the second search space, the second DCI with the first DCI format indicating a second entry of the first PDSCH time domain allocation list.

5. The wireless device of claim 4 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive a second TB, in a second slot and via a second PDSCH resource, determined based on the second entry, wherein the second TB is associated with a second hybrid automatic repeat request process.

6. The wireless device of claim 1 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive each TB of the TBs in a respective slot of the first slots.

7. The wireless device of claim 1 , wherein the first entry of the second PDSCH time domain allocation list indicates the PDSCH resources in the first slots, and wherein each of the PDSCH resources in a respective slot of the first slots is associated with:
a slot offset indication; and
a starting symbol and length indication.

8. 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, to a wireless device, radio resource control (RRC) messages comprising configuration parameters comprising:
a first physical downlink shared channel (PDSCH) time domain allocation list associated with a first downlink control information (DCI) format for scheduling a PDSCH in a slot; and
a second PDSCH time domain allocation list associated with a second DCI format for scheduling multiple PDSCHs in multiple slots, wherein each entry of the second PDSCH time domain allocation list indicates the multiple slots for the multiple PDSCHs;

transmit a first DCI with the second DCI format indicating a first entry of the second PDSCH time domain allocation list; and
transmit transport blocks (TBs), in first slots and via PDSCH resources, determined based on the first entry, wherein each of the TBs is associated with a respective hybrid automatic repeat request process.

9. The base station of claim 8 , wherein the configuration parameters cause the wireless device to monitor a first search space for receiving the first DCI with the second DCI format, wherein a first monitoring periodicity of the first search space is greater than a second monitoring periodicity of a second search space for receiving a second DCI with the first DCI format.

10. The base station of claim 9 , wherein the first search space is a wireless device specific search space and the second search space is a common search space.

11. The base station of claim 9 , wherein the instructions, when executed by the one or more processors, further cause the base station to transmit the second DCI with the first DCI format indicating a second entry of the first PDSCH time domain allocation list.

12. The base station of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the base station to transmit, a second TB, in a second slot and via a second PDSCH resource, determined based on the second entry, wherein the second TB is associated with a second hybrid automatic repeat request process.

13. The base station of claim 8 , wherein the instructions, when executed by the one or more processors, further cause the base station to transmit each TB of the TBs in a respective slot of the first slots.

14. The base station of claim 8 , wherein the first entry of the second PDSCH time domain allocation list indicates the PDSCH resources in the first slots, and wherein each of the PDSCH resources in a respective slot of the first slots is associated:
a slot offset indication; and
a starting symbol and length indication.

15. 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 radio resource control (RRC) messages comprising configuration parameters comprising:
a first physical downlink shared channel (PDSCH) time domain allocation list associated with a first downlink control information (DCI) format for scheduling a PDSCH in a slot; and
a second PDSCH time domain allocation list associated with a second DCI format for scheduling multiple PDSCHs in multiple slots, wherein each entry of the second PDSCH time domain allocation list indicates the multiple slots for the multiple PDSCHs;

receive a first DCI with the second DCI format indicating a first entry of the second PDSCH time domain allocation list; and
receive transport blocks (TBs), in first slots and via PDSCH resources, determined based on the first entry, wherein each of the TBs is associated with a respective hybrid automatic repeat request process.

16. The non-transitory computer-readable medium of claim 15 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to monitor a first search space for receiving the first DCI with the second DCI format, wherein a first monitoring periodicity of the first search space is greater than a second monitoring periodicity of a second search space for receiving a second DCI with the first DCI format.

17. The non-transitory computer-readable medium of claim 16 , wherein the first search space is a wireless device specific search space and the second search space is a common search space.

18. The non-transitory computer-readable medium of claim 16 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive, based on monitoring the second search space, the second DCI with the first DCI format indicating a second entry of the first PDSCH time domain allocation list.
