A method for configuring a Paging Occasion, PO, comprising: receiving, by a terminal, first configuration information from a network device, wherein the first configuration information is used by the terminal to determine at least one first PO, each of the at least one first PO is associated with at least one second PO, wherein the first configuration information comprises first information indicating the number of second POs associated with each first PO, and correspondences between the second POs and Physical Downlink Control Channel, PDCCH, occasions are predefined through a protocol, wherein the number of first POs configured in the first configuration information is M, and the number of the second POs associated with each first PO is N; a starting PDCCH occasion of a (i_s+1)-th first PO among the M first POs is a first PDCCH occasion, and a starting PDCCH occasion of a m-th second PO among N second POs associated with the (i_s+1)-th first PO is a second PDCCH occasion; and a deviation between the second PDCCH occasion and the first PDCCH occasion is m*S PDCCH occasions, wherein 1≤i_s+1≤M, 1≤m≤N, S is the number of SSBs actually transmitted from the network device to the terminal, and M, N, i_s+1, m and S are positive integers, wherein the method is characterized in that: each first PO and each of the at least one second PO associated with the first PO are used by the network device to transmit scheduling information of a paging Physical Downlink Shared Channel, PDSCH, from the network device to the terminal, and a first PO and each of the at least one second PO associated with the first PO are used by the network device to transmit the scheduling information of different paging PDSCHs respectively; or a first PO and each of the at least one second PO associated with the first PO are used by the network device to transmit the scheduling information of a same paging PDSCH. receiving, by a terminal, first configuration information from a network device, wherein the first configuration information is used by the terminal to determine at least one first PO, each of the at least one first PO is associated with at least one second PO, wherein the first configuration information comprises first information indicating the number of second POs associated with each first PO, and correspondences between the second POs and Physical Downlink Control Channel, PDCCH, occasions are predefined through a protocol, wherein the number of first POs configured in the first configuration information is M, and the number of the second POs associated with each first PO is N; a starting PDCCH occasion of a (i_s+1)-th first PO among the M first POs is a first PDCCH occasion, and a starting PDCCH occasion of a m-th second PO among N second POs associated with the (i_s+1)-th first PO is a second PDCCH occasion; and a deviation between the second PDCCH occasion and the first PDCCH occasion is m*S PDCCH occasions, wherein 1≤i_s+1≤M, 1≤m≤N, S is the number of SSBs actually transmitted from the network device to the terminal, and M, N, i_s+1, m and S are positive integers, wherein the method is characterized in that: each first PO and each of the at least one second PO associated with the first PO are used by the network device to transmit scheduling information of a paging Physical Downlink Shared Channel, PDSCH, from the network device to the terminal, and a first PO and each of the at least one second PO associated with the first PO are used by the network device to transmit the scheduling information of different paging PDSCHs respectively; or a first PO and each of the at least one second PO associated with the first PO are used by the network device to transmit the scheduling information of a same paging PDSCH. each first PO and each of the at least one second PO associated with the first PO are used by the network device to transmit scheduling information of a paging Physical Downlink Shared Channel, PDSCH, from the network device to the terminal, and a first PO and each of the at least one second PO associated with the first PO are used by the network device to transmit the scheduling information of different paging PDSCHs respectively; or a first PO and each of the at least one second PO associated with the first PO are used by the network device to transmit the scheduling information of a same paging PDSCH.
