Abstract

A wireless device receives configuration parameters indicating a first PDSCH processing capability value associated with a first power state of a cell, and a second PDSCH processing capability value associated with a second power state of the cell. The first PDSCH processing capability value indicates a first applicable gap between receiving a TB and transmitting an acknowledgement when the cell is in the first power state. The second PDSCH processing capability value indicates a second applicable gap between receiving a TB and transmitting an acknowledgement when the cell is in the second power state. A first TB is processed based on the first PDSCH processing capability value, when the cell in the first power state. A command is received indicating transitioning to the second power state. A second TB is processed based on the second PDSCH processing capability value, in response to transitioning to the second power state.

First claim

What is claimed is:

1. A method comprising:
receiving, by a wireless device, one or more radio resource control (RRC) messages comprising configuration parameters indicating:
a first physical downlink shared channel (PDSCH) processing capability value, indicating a first processing time threshold applicable to a gap between receiving a transport block (TB) and transmitting an acknowledgement, associated with a first power state of a cell; and
a second PDSCH processing capability value, indicating a second processing time threshold applicable to a gap between receiving a TB and transmitting an acknowledgement, associated with a second power state of the cell;

processing, based on the first PDSCH processing capability value, a first TB received on the cell in the first power state;
receiving a command indicating transitioning from the first power state to the second power state; and
processing, in response to transitioning to the second power state and based on the second PDSCH processing capability value, a second TB received on the cell.

2. The method of claim 1 , wherein the first power state comprises a time duration during which the cell is in an active state.

3. The method of claim 1 , wherein the second power state comprises a power saving state of the cell.

4. The method of claim 1 , further comprising switching from a first bandwidth part (BWP), of the cell, to a second BWP, of the cell, as being in an active state in response to transitioning from the first power state to the second power state.

5. The method of claim 1 , further comprising switching to a power saving mode on an active BWP of the cell in response to transitioning from the first power state to the second power state.

6. The method of claim 1 , wherein the second PDSCH processing capability value is associated with a BWP of the cell.

7. The method of claim 6 , wherein the second TB received on the cell is processed further based on the second PDSCH processing capability value in response to:
the second PDSCH processing capability value being associated with the BWP of the cell; and
the BWP being in an active state.

8. The method of claim 1 , wherein the processing the first TB comprises transmitting a first acknowledgement for the first TB at a time determined based on the first processing time threshold indicated by the first PDSCH processing capability value.

9. The method of claim 8 , wherein the processing the first TB comprises transmitting the first acknowledgement for the first TB in response to a timing value, indicated by a hybrid automatic repeat request (HARQ) feedback timing indicator of a first downlink control information (DCI) for the first TB, being greater than the first processing time threshold.

10. The method of claim 8 , wherein the processing the first TB comprises not transmitting the first acknowledgement for the first TB in response to a timing value, indicated by a HARQ feedback timing indicator of a first DCI for the first TB, being less than the first processing time threshold.

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 one or more radio resource control (RRC) messages comprising configuration parameters indicating:
a first physical downlink shared channel (PDSCH) processing capability value, indicating a first processing time threshold applicable to a gap between receiving a transport block (TB) and transmitting an acknowledgement, associated with a first power state of a cell; and
a second PDSCH processing capability value, indicating a second processing time threshold applicable to a gap between receiving a TB and transmitting an acknowledgement, associated with a second power state of the cell;

process, based on the first PDSCH processing capability value, a first TB received on the cell in the first power state;
receive a command indicating transitioning from the first power state to the second power state; and
process, in response to transitioning to the second power state and based on the second PDSCH processing capability value, a second TB received on the cell.

12. The wireless device of claim 11 , wherein the first power state comprises a time duration during which the cell is in an active state.

13. The wireless device of claim 11 , wherein the second power state comprises a power saving state of the cell.

14. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to switch from a first bandwidth part (BWP), of the cell, to a second BWP, of the cell, as being in an active state in response to transitioning from the first power state to the second power state.

15. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to switch to a power saving mode on an active BWP of the cell in response to transitioning from the first power state to the second power state.

16. The wireless device of claim 11 , wherein the second PDSCH processing capability value is associated with a BWP of the cell.

17. The wireless device of claim 16 , wherein the second TB received on the cell is processed further based on the second PDSCH processing capability value in response to:
the second PDSCH processing capability value being associated with the BWP of the cell; and
the BWP being in an active state.

18. The wireless device of claim 11 , wherein the processing the first TB comprises transmitting a first acknowledgement for the first TB at a time determined based on the first processing time threshold indicated by the first PDSCH processing capability value.

19. The wireless device of claim 18 , wherein the processing the first TB comprises transmitting the first acknowledgement for the first TB in response to a timing value, indicated by a hybrid automatic repeat request (HARQ) feedback timing indicator of a first downlink control information (DCI) for the first TB, being greater than the first processing time threshold.

20. A system comprising:
a base station comprising:
one or more first processors; and
memory storing first instructions that, when executed by the one or more first processors, cause the base station to:
transmit one or more radio resource control (RRC) messages comprising configuration parameters indicating:
a first physical downlink shared channel (PDSCH) processing capability value, indicating a first processing time threshold applicable to a gap between receiving a transport block (TB) and transmitting an acknowledgement, associated with a first power state of a cell; and
a second PDSCH processing capability value, indicating a second processing time threshold applicable to a gap between receiving a TB and transmitting an acknowledgement, associated with a second power state of the cell;

transmit a command indicating transitioning from the first power state to the second power state; and

a wireless device comprising:
one or more second processors; and
