Paging Early Indication of Paging Occasion

A method comprising:

• transmitting, by a base station to a wireless device, a system information block 1 (SIB1) message indicating:
• a first number of physical downlink control channel (PDCCH) monitoring occasions (MOs), for the wireless device to receive a paging early indication (PEI), of a PEI occasion associated with a paging occasion;
• a second number of PDCCH Mos, for receiving a paging message, of the paging occasion;
• and
• a third number of synchronization signal blocks (SSBs);
• skipping transmitting, a first PDCCH for transmitting the PEI, over the first number of PDCCH MOs, in response to each of the first number of PDCCH MOs, of the PEI occasion, overlapping with at least one resource element (RE) of an SSB of the third number of SSBs;
• and
• in response to the skipping transmitting the first PDCCH, transmitting, over the second number of PDCCH MOs of a second PDCCH, downlink control information (DCI) scheduling the paging message.

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 control (RRC) messages comprising:
• first configuration parameters, of a paging early indication (PEI), indicating a first control resource set (coreset) for receiving the PEI;
• second configuration parameters, of a paging occasion, indicating a physical downlink control channel (PDCCH) monitoring occasion for receiving a paging message;
• and
• third configuration parameters of a multicast and broadcast service (MBS);
• based on monitoring a first PDCCH for the MBS:
• skip monitoring the PEI;
• and
• monitor the paging message in the paging occasion;
• and
• receive, based on receiving downlink control information (DCI), the paging message based on the second configuration parameters indicating the PDCCH monitoring occasion.
