Power Saving for Paging Message Reception

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 indicating monitoring occasions of a first physical downlink control channel (PDCCH) for receiving a first downlink control information (DCI) comprising:
• a paging early indication (PEI) indicating whether to monitor paging occasions for receiving a second DCI scheduling a paging message;
• and
• a tracking reference signal (TRS) availability indication indicating whether a TRS is available;
• in response to the monitoring occasions for receiving the first DCI being skipped by the wireless device, determine:
• that the TRS is unavailable for the wireless device;
• and
• to transmit the second DCI via the paging occasions;
• and
• transmit, to the wireless device via the paging occasions and using a synchronization signal block (SSB) based on the TRS being unavailable, the second DCI scheduling the paging message.

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 indicating monitoring occasions of a first physical downlink control channel (PDCCH) for receiving a first downlink control information (DCI) comprising:
• a paging early indication (PEI) indicating whether to monitor paging occasions for receiving a second DCI scheduling a paging message;
• and
• a tracking reference signal (TRS) availability indication indicating whether a TRS is available;
• in response to skipping monitoring the monitoring occasions for receiving the first DCI:
• determine that the TRS is unavailable;
• and
• monitor the paging occasions;
• and
• receive, via the paging occasions and using a synchronization signal block (SSB) based on the TRS being unavailable, the second DCI scheduling the paging message.
