receiving, from the base station, a PDCCH addressed to a paging radio network temporary identifier (P-RNTI) on the downlink BWP based on the at least one parameter and the information.

2. The method of claim 1, wherein the downlink BWP is a non-initial downlink BWP, and

wherein the at least one parameter includes a paging cycle duration, a number of paging frames in a paging cycle, a number of paging occasions in a paging frame, and a paging frame offset.

3. The method of claim 2, wherein the receiving of the PDCCH addressed to the P-RNTI comprises:

identifying at least one PDCCH monitoring occasion based on the at least one parameter and the information; and

monitoring a PDCCH in the at least one PDCCH monitoring occasion.

4. The method of claim 1, further comprising, receiving, from the base station, a paging message on an initial downlink BWP based on the at least one parameter, and

wherein the at least one parameter includes a paging cycle duration, a number of paging frames in a paging cycle, a number of paging occasions in a paging frame, a paging frame offset, and a first PDCCH monitoring occasion for a PO of a PF on the initial downlink BWP.

5. The method of claim 1, wherein a paging message is received on an initial downlink BWP, in case that the terminal is in a radio resource control (RRC) idle state, and

wherein a paging message is received on a non-initial downlink BWP, in case that the terminal is in an RRC connected state.

6. A method of transmitting a paging by a base station in a wireless communication system, the method comprising:

transmitting, to a terminal, a system information block (SIB) including at least one parameter for a paging;

transmitting, to the terminal, a message configuring a downlink bandwidth part (BWP), the message including information indicating a first physical downlink control channel (PDCCH) monitoring occasion for a paging occasion (PO) of a paging frame (PF) on the downlink BWP; and

transmitting, to the terminal, a PDCCH addressed to a paging radio network temporary identifier (P-RNTI) on the downlink BWP based on the at least one parameter and the information.

7. The method of claim 6, wherein the downlink BWP is a non-initial downlink BWP, and

wherein the at least one parameter includes a paging cycle duration, a number of paging frames in a paging cycle, a number of paging occasions in a paging frame, and a paging frame offset.

8. The method of claim 7, wherein the PDCCH addressed to the P-RNTI is received by the terminal by:

identifying at least one PDCCH monitoring occasion based on the at least one parameter and the information; and

monitoring a PDCCH in the at least one PDCCH monitoring occasion.

9. The method of claim 6, further comprising, transmitting, to the terminal, a paging message on an initial downlink BWP based on the at least one parameter, and

wherein the at least one parameter includes a paging cycle duration, a number of paging frames in a paging cycle, a number of paging occasions in a paging frame, a paging frame offset, and a first PDCCH monitoring occasion for a PO of a PF on the initial downlink BWP.

10. The method of claim 6, wherein a paging message is transmitted on an initial downlink BWP, in case that the terminal is in a radio resource control (RRC) idle state, and

wherein a paging message is transmitted on a non-initial downlink BWP, in case that the terminal is in a RRC connected state.
