The first DCI may comprise: 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, the wireless device may: determine that the TRS is unavailable, and monitor the paging occasions. The wireless device may 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. ## Claims ### Claim 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 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. ### Claim 2 (depends on 1) The wireless device of claim 1, wherein instructions further cause the wireless device to skip monitoring the monitoring occasions in response to the monitoring occasions overlapping with at least one SSB. ### Claim 3 (depends on 2) The wireless device of claim 2, wherein all of the monitoring occasions overlap with the at least one SSB. ### Claim 4 (depends on 1) The wireless device of claim 1, wherein the configuration parameters further indicate that TRSs are configured. ### Claim 5 (depends on 1) The wireless device of claim 1, wherein the wireless device is in a radio resource control (RRC) inactive state or an RRC idle state. ### Claim 6 (depends on 1) The wireless device of claim 1, wherein the TRS is determined to be unavailable based on not receiving the first DCI. ### Claim 7 (depends on 1) The wireless device of claim 1, wherein the wireless device synchronizes with the SSB for the receiving the second DCI. ### Claim 8 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. ### Claim 9 (depends on 3) The base station of claim 3, wherein the wireless device skips monitoring the monitoring occasions in response to the monitoring occasions overlapping with at least one SSB. ### Claim 10 (depends on 9) The base station of claim 9, wherein all of the monitoring occasions overlap with the at least one SSB. ### Claim 11 (depends on 3) The base station of claim 3, wherein the configuration parameters further indicate that TRSs are configured. ### Claim 12 (depends on 3) The base station of claim 3, wherein the wireless device is in a radio resource control (RRC) inactive state or an RRC idle state. ### Claim 13 (depends on 3) The base station of claim 3, wherein the TRS is determined to be unavailable based on not receiving the first DCI. ### Claim 14 (depends on 3) The base station of claim 3, wherein the wireless device synchronizes with the SSB for the receiving the second DCI. ### Claim 15 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. ### Claim 16 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein instructions further cause the wireless device to skip monitoring the monitoring occasions in response to the monitoring occasions overlapping with at least one SSB. ### Claim 17 (depends on 16) The non-transitory computer-readable medium of claim 16, wherein all of the monitoring occasions overlap with the at least one SSB. ### Claim 18 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the configuration parameters further indicate that TRSs are configured. ### Claim 19 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the wireless device is in a radio resource control (RRC) inactive state or an RRC idle state. ### Claim 20 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein: the TRS is determined to be unavailable based on not receiving the first DCI;
