Abstract

Embodiments provide a paging method and apparatus. The method includes receiving, by user equipment (UE), a system message broadcast by a base station, where the system message carries a system parameter and configuration information of a paging message, and the configuration information includes time-frequency information of the paging message. The method also includes determining, by the UE, a paging cycle, a paging frame (PF) and a paging occasion (PO) subframe according to the system parameter, and determining, by the UE according to the configuration information, a time-frequency resource occupied by the paging message in the PO subframe. The method also includes detecting, by the UE within the paging cycle according to the PF, the PO subframe, and the time-frequency resource, whether the paging message exists in a physical downlink shared channel PDSCH.

First claim

What is claimed is:

2 . The method according to claim 1 , wherein:
the configuration information further comprises mode information of the PO subframe, wherein the mode information specifies a PO subframe occupied by the base station for sending the paging message; and determining, by the UE, the paging cycle, the PF and the PO subframe according to the system parameter comprises:
determining, by the UE, the paging cycle according to the system parameter;
determining, by the UE, the PF according to the system parameter and the paging cycle; and
determining, by the UE, the PO subframe according to the PF and the mode information.

3 . The method according to claim 2 , wherein, in response to the configuration information comprising a plurality of pieces of the mode information, before determining, by the UE, the PO subframe according to the PF and the mode information, the method further comprises:
selecting, by the UE according to a coverage enhancement level of the UE, corresponding mode information.

4 . The method according to claim 1 , wherein:
the configuration information further comprises an extension coefficient of the paging cycle; and determining the paging cycle comprises:
determining the paging cycle according to the system parameter and the extension coefficient.

5 . The method according to claim 1 , wherein:
the paging message comprises allocation information of an uplink resource of the UE; and after detecting, by the UE according to the PF, the PO subframe, and the time-frequency resource, whether the paging message exists in the PDSCH, the method further comprises:
in response to the UE detecting that the paging message for the UE exists in the PDSCH, determining, by the UE, the uplink resource according to the allocation information; and
sending, by the UE, uplink data or signaling on the uplink resource to the base station.

6 . A paging method, comprising:
broadcasting, by a base station, a system message to a user equipment (UE), wherein the system message carries a system parameter and configuration information of a paging message, and the configuration information comprises time-frequency information of the paging message; wherein the system message instructs the UE to determine a paging cycle, a paging frame (PF) and a paging occasion (PO) subframe according to the system parameter, and to determine, according to the time-frequency information, a time-frequency resource occupied by the paging message in the PO subframe.

7 . The method according to claim 6 , wherein:
the configuration information further comprises mode information of the PO subframe, wherein the mode information specifies the PO subframe occupied by the base station for sending the paging message; or the configuration information further comprises an extension coefficient of the paging cycle.

8 . The method according to claim 6 , further comprising:
sending, by the base station within the paging cycle and according to the PF, the PO subframe, and the time-frequency resource, the paging message to the UE using a physical downlink shared channel (PDSCH).

9 . The method according to claim 8 , wherein:
the paging message comprises allocation information of an uplink resource of the UE, and the allocation information instructs the UE to send, to the base station, uplink data or signaling on the uplink resource determined according to the allocation information.

10 . A paging apparatus, comprising:
a receiver, configured to receive a system message broadcast by a base station, wherein the system message carries a system parameter and configuration information of a paging message, and the configuration information comprises time-frequency information of the paging message; a processor; and a computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
obtaining the system message from the receiver;
determining a paging cycle, a paging frame (PF) and a paging occasion (PO) subframe according to the system parameter;
determining, according to the configuration information, a time-frequency resource occupied by the paging message in the PO subframe; and
detecting, within the paging cycle according to the PF, the PO subframe, and the time-frequency resource, whether the paging message exists in a physical downlink shared channel (PDSCH).

11 . The apparatus according to claim 10 , wherein:
the configuration information further comprises mode information of the PO subframe, wherein the mode information specifies the PO subframe occupied by the base station for sending the paging message; and the program further includes instructions for:
