and determining whether or not a paging indicator field is comprised in the first DCI. ## Claims ### Claim 1 A method performed by a user equipment (UE) operating in a wireless communication system, the method comprising: receiving downlink control information (DCI) that comprises a cyclic redundancy check (CRC) scrambled by a paging radio network temporary identifier (P-RNTI) and based on the DCI including both (i) scheduling information for paging and (ii) a message for system information: determining the scheduling information for paging from a first bit field of the DCI; and determining the message for system information from a second bit field of the DCI. ### Claim 2 (depends on 1) The method of claim 1, wherein the DCI further comprises indication information that indicates whether the DCI includes at least one of (i) the scheduling information for paging or (ii) the message for system information. ### Claim 3 (depends on 2) The method of claim 2, further comprising: based on the indication information indicating that the DCI includes both (i) the scheduling information for paging and (ii) the message for system information: receiving a paging message based on the scheduling information for paging; and receiving updated system information based on the message for the system information. ### Claim 4 (depends on 1) The method of claim 1, wherein the message for system information includes an indication of system information modification, an indication for earthquake tsunami warning system (ETWS) notification, or an indication of commercial mobile alert system (CMAS) notification. ### Claim 5 (depends on 1) The method of claim 1, wherein the scheduling information for paging includes time resource assignment information, frequency resource assignment information, and modulation and coding scheme (MCS) information. ### Claim 6 A user equipment (UE) configured to operate in a wireless communication system, the UE comprising: a transceiver; at least one processor; and at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising: receiving downlink control information (DCI) that comprises a cyclic redundancy check (CRC) scrambled by a paging radio network temporary identifier (P-RNTI) and based on the DCI including both (i) scheduling information for paging and (ii) a message for system information: determining the scheduling information for paging from a first bit field of the DCI; and determining the message for system information from a second bit field of the DCI. ### Claim 7 (depends on 6) The UE of claim 6, wherein the DCI further comprises indication information that indicates whether the DCI includes at least one of (i) the scheduling information for paging or (ii) the message for system information. ### Claim 8 (depends on 7) The UE of claim 7, wherein the operations further comprise: based on the indication information indicating that the DCI includes both (i) the scheduling information for paging and (ii) the message for system information: receiving a paging message based on the scheduling information for paging; and receiving updated system information based on the message for the system information. ### Claim 9 (depends on 7) The UE of claim 7, wherein the message for system information includes an indication of system information modification, an indication for earthquake tsunami warning system (ETWS) notification, or an indication of commercial mobile alert system (CMAS) notification. ### Claim 10 (depends on 6) The UE of claim 6, wherein the scheduling information for paging includes time resource assignment information, frequency resource assignment information, and modulation and coding scheme (MCS) information. ### Claim 11 A method performed by a base station (BS) operating in a wireless communication system, the method comprising: transmitting downlink control information (DCI) that comprises a cyclic redundancy check (CRC) scrambled by a paging radio network temporary identifier (P-RNTI), wherein based on the DCI including both (i) scheduling information for paging and (ii) a message for system information: the scheduling information for paging is included in a first bit of the DCI, and the message for system information is included in a second bit field of the DCI. ### Claim 12 (depends on 11) The method of claim 11, wherein the DCI further comprises indication information that indicates whether the DCI includes at least one of (i) the scheduling information for paging or (ii) the message for system information. ### Claim 13 (depends on 12) The method of claim 12, further comprising: based on the indication information indicating that the DCI includes both (i) the scheduling information for paging and (ii) the message for system information: transmitting a paging message based on the scheduling information for paging; and transmitting updated system information based on the message for the system information. ### Claim 14 (depends on 11) The method of claim 11, wherein the message for system information includes an indication of system information modification, an indication for earthquake tsunami warning system (ETWS) notification, or an indication of commercial mobile alert system (CMAS) notification. ### Claim 15 (depends on 11) The method of claim 11, wherein the scheduling information for paging includes time resource assignment information, frequency resource assignment information, and modulation and coding scheme (MCS) information. ### Claim 16 A base station (BS) configured to operate in a wireless communication system, the BS comprising: a transceiver; at least one processor; and at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising: transmitting downlink control information (DCI) that comprises a cyclic redundancy check (CRC) scrambled by a paging radio network temporary identifier (P-RNTI), wherein based on the DCI including both (i) scheduling information for paging and (ii) a message for system information: the scheduling information for paging is included in a first bit of the DCI, and the message for system information is included in a second bit field of the DCI. ### Claim 17 (depends on 16) The BS of claim 16, wherein the DCI comprises indication information that indicates whether the DCI includes at least one of (i) the scheduling information for paging or (ii) the message for system information. ### Claim 18 (depends on 17) The BS of claim 17, wherein the operations further comprise: based on the indication information indicating that the DCI includes both (i) the scheduling information for paging and (ii) the message for system information: transmitting a paging message based on the scheduling information for paging; and transmitting updated system information based on the message for the system information. ### Claim 19 (depends on 16) The BS of claim 16, wherein the message for system information includes an indication of system information modification, an indication for earthquake tsunami warning system (ETWS) notification, or an indication of commercial mobile alert system (CMAS) notification. ### Claim 20 (depends on 16) The BS of claim 16, wherein the scheduling information for paging includes time resource assignment information, frequency resource assignment information, and modulation and coding scheme (MCS) information.
