Paging method and apparatus utilizing PDCCH
Embodiments of this application provide a paging method, including: sending, by a network device, paging-related information at a specified time, where the paging-related information is sent in a beam sweeping manner. A paging message is obtained based on the paging-related information.
1. A method, comprising:
sending, by a network device, paging-related information of a paging message through a physical downlink control channel (PDCCH), the paging message comprising a first part and a second part, wherein the paging-related information comprises following information without comprising the second part of the paging message:
indication information for a user equipment to receive the paging message, the first part of the paging message comprising a system message update indication (systemInfoModification), and resource location information for locating the second part of the paging message; and
signaling, by the network device, that the paging message comprises the second part.
2. The method according to claim 1 , wherein
the indication information for the user equipment to receive the paging message is a paging radio network temporary identifier (P-RNTI).
3. The method according to claim 1 , wherein the paging-related information comprises an indication indicating whether the second part of the paging message exists.
4. The method according to claim 3 , wherein the indication indicating whether the second part of the paging message exists is a 1-bit indication.
5. A method, comprising:
receiving, by a user equipment, paging-related information of a paging message from a network device through a physical downlink control channel (PDCCH), the paging message comprising a first part and a second part, with the paging-related information not including the second part of the paging message;
obtaining, by the user equipment, the paging-related information, wherein the paging-related information comprises:
indication information for the user equipment to receive the paging message, the first part of the paging message comprising a system message update indication (systemInfoModification), and resource location information for locating the second part of the paging message; and
receiving, by the user equipment, signaling indicating that the paging message comprises the second part.
6. The method according to claim 5 , further comprising:
obtaining, by the user equipment, the second part of the paging message according to the signaling and the resource location information.
7. The method according to claim 5 , wherein
the indication information for the user equipment to receive the paging message is a paging radio network temporary identifier (P-RNTI).
8. The method according to claim 5 , wherein the paging-related information comprises an indication indicating whether the second part of the paging message exists.
9. The method according to claim 8 , wherein the indication indicating whether the second part of the paging message exists is a 1-bit indication.
10. A communication device, comprising a transceiver:
the transceiver is configured to:
send paging-related information of a paging message through a physical downlink control channel (PDCCH), the paging message comprising a first part and a second part, wherein the paging-related information comprises following information without comprising the second part of the paging message:
indication information for a user equipment to receive the paging message, the first part of the paging message comprising a system message update indication (systemInfoModification), and resource location information for locating the second part of the paging message; and
signal that the paging message comprises the second part.
11. The communication device according to claim 10 , wherein
the indication information for the user equipment to receive the paging message is a paging radio network temporary identifier (P-RNTI).
12. The communication device according to claim 10 , wherein the paging-related information comprises an indication indicating whether the second part of the paging message exists.
13. A communication device, comprising a processor and a transceiver,
wherein the transceiver is configured to receive paging-related information of a paging message from a network device through a physical downlink control channel (PDCCH), the paging message comprising a first part and a second part, with the paging-related information not including the second part of the paging message; and
wherein the processor is configured to obtain the paging-related information;
wherein the paging-related information comprises indication information for the communication device to receive the paging message, the first part of the paging message comprising a system message update indication (systemInfoModification), and resource location information for locating the second part of the paging message; and
wherein the transceiver is further configured to receive signaling indicating that the paging message comprises the second part.
14. The communication device according to claim 13 , wherein
the indication information for the communications device to receive the paging message is a paging radio network temporary identifier (P-RNTI).
15. The communication device according to claim 13 , wherein the paging-related information comprises an indication indicating whether the second part of the paging message exists.
