Abstract

A wireless device may receive CSI report configuration parameters for CSI reports via a first cell. The wireless device may further receive a time pattern configuration parameter indicating first timings that the first cell is a PUCCH cell in a PUCCH group and second timings that a second cell is the PUCCH cell in the PUCCH group. The wireless device may transmit a first CSI report, scheduled for transmission in a first report timing via the first cell, based on the first report timing being within the first timings. The wireless device may drop a second CSI report, scheduled for transmission in a second report timing via the first cell, based on the second report timing being within the second timings.

First claim

What is claimed is:

1 . A non-transitory computer-readable medium storing instructions that, when executed, cause a wireless device to:
receive:
first configuration parameters of a physical uplink control channel (PUCCH) group comprising a first cell and a second cell;
channel state information (CSI) report configuration parameters for CSI reports via the first cell; and
a second configuration parameter of a time domain pattern indicating first timings that the first cell is the PUCCH cell for PUCCH transmission in the PUCCH group and second timings that the second cell is the PUCCH cell for PUCCH transmission in the PUCCH group;
transmit a first CSI report, scheduled for transmission via the first cell in a first report timing, based on the first report timing being within the first timings; and drop a second CSI report, scheduled for transmission via the first cell in a second report timing, based on the second report timing being within the second timings.

2 . The non-transitory computer-readable medium of claim 1 , wherein the CSI report configuration parameters are for periodic CSI reports or semi-persistent CSI reports.

3 . The non-transitory computer-readable medium of claim 1 , wherein the CSI report configuration parameters are for transmission of CSI reports via a PUCCH of the first cell.

4 . The non-transitory computer-readable medium of claim 1 , wherein the time domain pattern indicates a cell switching pattern for PUCCH transmission.

5 . The non-transitory computer-readable medium of claim 1 , wherein the first report timing and the second report timing are based on the CSI report configuration parameters.

6 . The non-transitory computer-readable medium of claim 1 , wherein the first report timing and the second report timing are based on a subcarrier spacing of an active bandwidth part of the first cell.

7 . The non-transitory computer-readable medium of claim 1 , wherein the first timings and the second timings are based on a reference subcarrier spacing.

8 . The non-transitory computer-readable medium of claim 7 , wherein the reference subcarrier spacing is a first subcarrier spacing associated with the first cell.

9 . The non-transitory computer-readable medium of claim 1 , wherein the PUCCH group is a primary PUCCH group.

10 . The non-transitory computer-readable medium of claim 1 , wherein the PUCCH group is a secondary PUCCH group.

11 . A non-transitory computer-readable medium storing instructions that, when executed, cause a base station to:
transmit:
first configuration parameters of a physical uplink control channel (PUCCH) group comprising a first cell and a second cell;
channel state information (CSI) report configuration parameters for CSI reports via the first cell; and
a second configuration parameter of a time domain pattern indicating first timings that the first cell is the PUCCH cell for PUCCH transmission in the PUCCH group and second timings that the second cell is the PUCCH cell for PUCCH transmission in the PUCCH group;
receive a first CSI report, scheduled for transmission via the first cell in a first report timing, based on the first report timing being within the first timings; and wherein a second CSI report, scheduled for transmission via the first cell in a second report timing, is dropped based on the second report timing being within the second timings.

12 . The non-transitory computer-readable medium of claim 11 , wherein the CSI report configuration parameters are for periodic CSI reports or semi-persistent CSI reports.

13 . The non-transitory computer-readable medium of claim 11 , wherein the CSI report configuration parameters are for transmission of CSI reports via a PUCCH of the first cell.

14 . The non-transitory computer-readable medium of claim 11 , wherein the time domain pattern indicates a cell switching pattern for PUCCH transmission.

15 . The non-transitory computer-readable medium of claim 11 , wherein the first report timing and the second report timing are based on the CSI report configuration parameters.

16 . The non-transitory computer-readable medium of claim 11 , wherein the first report timing and the second report timing are based on a subcarrier spacing of an active bandwidth part of the first cell.

17 . The non-transitory computer-readable medium of claim 11 , wherein the first timings and the second timings are based on a reference subcarrier spacing.

18 . The non-transitory computer-readable medium of claim 17 , wherein the reference subcarrier spacing is a first subcarrier spacing associated with the first cell.

19 . The non-transitory computer-readable medium of claim 11 , wherein the PUCCH group is a primary PUCCH group.

20 . The non-transitory computer-readable medium of claim 11 , wherein the PUCCH group is a secondary PUCCH group.
