Abstract

Claims (72)

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 one or more radio resource configuration (RRC) messages comprising:

one or more channel state information (CSI) reporting settings, wherein a first CSI reporting setting comprises:

a report configuration identifier;

a report type indicating a semi-persistent (SP) report type; and

a periodicity parameter indicating a reporting periodicity; and

configuration parameters of a plurality of bandwidth parts (BWPs) of a cell;

receive an SP CSI activation/deactivation medium access control (MAC) control element (CE) comprising:

a BWP indicator indicating a first BWP, of the plurality of BWPs of the cell, for which CSI reporting is triggered; and

an SP CSI activation/deactivation bit indicating activation of the CSI reporting based on the first CSI reporting setting;

receive a first downlink control information (DCI) indicating switching to the first BWP as an active BWP;

activate the first BWP of the plurality of BWPs; and

based on the SP CSI activation/deactivation MAC CE indicating the activation of the CSI reporting and based on the first BWP being the active BWP, transmit one or more SP CSI reports based on the first CSI reporting setting.

2. The wireless device of claim 1 , wherein the instructions further cause the wireless device to not transmit any SP CSI reports in response to the SP CSI activation/deactivation MAC CE before receiving the first DCI.

3. The wireless device of claim 2 , wherein the instructions further cause the wireless device to:

receive a second DCI indicating switching from the first BWP to a second BWP as the active BWP; and

in response to switching from the first BWP to the second BWP as the active BWP:

deactivate the first BWP; and

stop transmission of further SP CSI reports based on the first CSI reporting setting.

4. The wireless device of claim 2 , wherein the instructions further cause the wireless device to:

receive a second SP CSI activation/deactivation MAC CE indicating deactivation of the CSI reporting based on the first CSI reporting setting; and

stop transmission of further SP CSI reports based on the first CSI reporting setting.

5. The wireless device of claim 4 , wherein the first DCI switches both a downlink BWP and an uplink BWP based on an association between the downlink BWP and the uplink BWP that allows one activation/deactivation command to switch both the DL BWP and the UL BWP.

6. The wireless device of claim 5 , wherein the first BWP is the downlink BWP.

7. The wireless device of claim 6 , wherein the first CSI reporting setting comprises an offset parameter indicating a reporting timing offset.

8. The wireless device of claim 4 , wherein the SP CSI activation/deactivation MAC CE comprises a plurality of SP CSI activation/deactivation bits, wherein for each of the plurality of SP CSI activation/deactivation bits:

a value of 1 indicates activation of CSI reporting based on a CSI reporting setting; and

a value of 0 indicates deactivation of CSI reporting based on the CSI reporting setting.

9. The wireless device of claim 8 , wherein the SP CSI activation/deactivation MAC CE indicates the report configuration identifier of the first CSI reporting setting.

10. The wireless device of claim 1 , wherein the instructions further cause the wireless device to:

receive a second DCI indicating switching from the first BWP to a second BWP as the active BWP; and

in response to switching from the first BWP to the second BWP as the active BWP:

deactivate the first BWP; and

stop transmission of further SP CSI reports based on the first CSI reporting setting.

11. The wireless device of claim 10 , wherein the plurality of BWPs comprises a plurality of downlink BWPs and a plurality of uplink BWPs.

12. The wireless device of claim 11 , wherein the first BWP is an uplink BWP.

13. The wireless device of claim 10 , wherein the SP CSI activation/deactivation MAC CE comprises a plurality of SP CSI activation/deactivation bits, wherein for each of the plurality of SP CSI activation/deactivation bits:

a value of 1 indicates activation of CSI reporting based on a CSI reporting setting; and

a value of 0 indicates deactivation of CSI reporting based on the CSI reporting setting.

14. The wireless device of claim 13 , wherein the BWP indicator indicates the first BWP for which SP CSI reporting is triggered by the SP CSI activation/deactivation MAC CE.

15. The wireless device of claim 10 , wherein the first DCI switches both a downlink BWP and an uplink BWP based on an association between the downlink BWP and the uplink BWP that allows one activation/deactivation command to switch both the DL BWP and the uplink BWP.

16. The wireless device of claim 15 , wherein the first BWP is the downlink BWP.

17. The wireless device of claim 16 , wherein the one or more RRC messages further comprise:

one or more CSI-reference signal (CSI-RS) resource settings; and

a CSI measurement setting.

18. The wireless device of claim 17 , wherein the first CSI reporting setting comprises an offset parameter indicating a reporting timing offset.

19. The wireless device of claim 17 , wherein the SP CSI activation/deactivation MAC CE is for multiple CSI reporting settings when multiple CSI reporting settings are supported for SP CSI.

20. The wireless device of claim 1 , wherein the SP CSI activation/deactivation MAC CE indicates one or more physical uplink control channel (PUCCH) resources for the one or more SP CSI reports.

21. The wireless device of claim 20 , wherein the instructions further cause the wireless device to not transmit any SP CSI reports in response to the SP CSI activation/deactivation MAC CE before receiving the first DCI.

22. The wireless device of claim 20 , wherein the instructions further cause the wireless device to:

receive a second DCI indicating switching from the first BWP to a second BWP as the active BWP; and

in response to switching from the first BWP to the second BWP as the active BWP:

deactivate the first BWP; and

stop transmission of further SP CSI reports based on the first CSI reporting setting.

23. The wireless device of claim 22 , wherein the instructions further cause the wireless device to:

receive a second SP CSI activation/deactivation MAC CE indicating deactivation of the CSI reporting based on the first CSI reporting setting; and

stop transmission of further SP CSI reports based on the first CSI reporting setting.

24. The wireless device of claim 23 , wherein the one or more RRC messages further comprise:
