Channel State Information Report for a Secondary Cell in Network Energy Saving

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, configuration parameters, of a secondary cell, SCell, comprising a first channel state information, CSI, report configuration associated with one or more first CSI resources comprising:
• one or more on-demand synchronization signal blocks, OD-SSBs, of OD-SSBs of the SCell, wherein the one or more OD-SSBs are activated by an OD-SSB activation medium access control control element, MAC CE;
• and
• one or more always-on SSBs of the SCell, wherein the one or more always-on SSBs are transmitted based on the configuration parameters, of the SCell, comprising a parameter indicating a frequency of the one or more always-on SSBs for the SCell;
• transmit the OD-SSB activation MAC CE indicating transmissions of the one or more OD-SSBs of the SCell;
• and
• receive, based on the OD-SSB activation MAC CE indicating the transmissions of the one or more OD-SSBs and after the SCell is activated based on a SCell activation/deactivation MAC CE, a first CSI report for the SCell according to the first CSI report configuration.

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 configuration parameters, of a secondary cell (SCell), comprising a first channel state information (CSI) report configuration associated with one or more first CSI resources comprising:
• one or more on-demand synchronization signal blocks (OD-SSBs) of OD-SSBs of the SCell, wherein the one or more OD-SSBs are activated by an OD-SSB activation medium access control control element (MAC CE);
• and
• one or more always-on SSBs of the SCell, wherein the one or more always-on SSBs are transmitted based on the configuration parameters, of the SCell, comprising a parameter indicating a frequency of the one or more always-on SSBs for the SCell;
• receive the OD-SSB activation MAC CE indicating transmissions of the one or more OD-SSBs of the SCell;
• and
• transmit, based on the OD-SSB activation MAC CE indicating the transmissions of the one or more OD-SSBs and after the SCell is activated based on a SCell activation/deactivation MAC CE, a first CSI report for the SCell according to the first CSI report configuration.
