The method for receiving system information update information may include: receiving, by a terminal device, paging downlink control information (DCI) which includes update information of one or more system information block (SIB) types; and acquiring, by the terminal device, the update information of the one or more SIB types from the paging DCI.
1. A method for receiving system information update information, comprising:
receiving, by a terminal device, paging downlink control information (DCI) which comprises update information of one or more system information block (SIB) types;
acquiring, by the terminal device, the update information of the one or more SIB types from the paging DCI; and
determining, by the terminal device, a manner of indicating the update information of the one or more SIB types in the paging DCI according to content of the paging DCI,
wherein the paging DCI comprises an indication used for indicating the content of the paging DCI, and the terminal device determines the manner of indicating the update information of the one or more SIB types in the paging DCI according to the indication,
wherein when the indication in the paging DCI indicates that the paging DCI comprises a short message and does not comprise scheduling information for a paging message, the terminal device determines that the manner of indicating the update information of the one or more SIB types in the paging DCI is that update information of each of the one or more SIB types is indicated by a bit or bit group in the paging DCI.
2. The method according to claim 1 , wherein the paging DCI comprises a bit or bit group indicating update information of each of the one or more SIB types.
3. The method according to claim 1 , wherein the paging DCI comprises a bit or bit group indicating update information of each of one or more SIB type groups, wherein at least one SIB type group in the one or more SIB type groups comprises a plurality of SIB types.
4. The method according to claim 1 , wherein when the indication in the paging DCI indicates that the paging DCI comprises a short message and scheduling information for a paging message, the terminal device determines that the manner of indicating the update information of the one or more SIB types in the paging DCI is that update information of each of one or more SIB type groups is indicated by a bit or bit group in the paging DCI, wherein at least one SIB type group in the one or more SIB type groups comprises a plurality of SIB types.
5. The method according to claim 1 , wherein the update information of the one or more SIB types is a part of the short message in the paging DCI.
6. The method according to claim 2 , wherein the bit or bit group in the paging DCI is used for indicating whether the each of the one or more SIB types is modified.
7. The method according to claim 3 , wherein the bit or bit group in the paging DCI is used for indicating whether the each of the one or more SIB type groups is modified.
8. The method according to claim 1 , further comprising: determining, by the terminal device, a manner of indicating the update information of the one or more SIB types in the paging DCI according to a predefined standard or according to notification of a network device through broadcast of system information or a radio resource control signaling.
9. A method for transmitting system information update information, comprising:
generating, by a network device, paging downlink control information (DCI), wherein the paging DCI comprises update information of one or more system information block (SIB) types;
transmitting, by the network device, the paging DCI comprising the update information of the one or more SIB types; and
notifying, by the network device, a terminal device of a manner of indicating the update information of the one or more SIB types in the paging DCI through broadcast of system information or a radio resource control signaling, so that the terminal device determines that the manner of indicating the update information of the one or more SIB types in the paging DCI is that update information of each of the one or more SIB types is indicated by a bit or bit group in the paging DCI,
wherein when the paging DCI comprises a short message and does not comprise scheduling information for a paging message, the paging DCI comprises a bit or bit group indicating update information of each of the one or more SIB types,
wherein the paging DCI comprises an indication used for indicating content of the paging DCI.
10. The method according to claim 9 , wherein the paging DCI comprises a bit or bit group indicating update information of each of the one or more SIB types,
or,
the paging DCI comprises a bit or bit group indicating update information of each of one or more SIB type groups, wherein at least one SIB type group in the one or more SIB type groups comprises a plurality of SIB types.
11. The method according to claim 9 , wherein when the paging DCI comprises a short message and scheduling information for a paging message, the paging DCI comprises a bit or bit group indicating update information of each of one or more SIB type groups, wherein at least one SIB type group in the one or more SIB type groups comprises a plurality of SIB types.
12. The method according to claim 9 , wherein the update information of the one or more SIB types is a part of the short message in the paging DCI.
13. A terminal device, comprising:
a transceiver, configured to receive paging downlink control information (DCI) which comprises update information of one or more system information block (SIB) types; and
a processor, configured to acquire the update information of the one or more SIB types from the paging DCI,
wherein the processor is further configured to acquire a manner of indicating the update information of the one or more SIB types in the paging DCI according to content of the paging DCI,
wherein the paging DCI comprises an indication used for indicating the content of the paging DCI, and the processor is further configured to acquire the manner of indicating the update information of the one or more SIB types in the paging DCI according to the indication,
wherein the processor is further configured to determine that, when the indication in the paging DCI indicates that the paging DCI comprises a short message and does not comprise scheduling information for a paging message, the manner of indicating the update information of the one or more SIB types in the paging DCI is that update information of each of the one or more SIB types is indicated by a bit or bit group in the paging DCI.
14. The terminal device according to claim 13 , wherein the processor is further configured to determine that, when the indication in the paging DCI indicates that the paging DCI comprises a short message and scheduling information for a paging message, the manner of indicating the update information of the one or more SIB types in the paging DCI is that update information of each of one or more SIB type groups is indicated by a bit or bit group in the paging DCI, wherein at least one SIB type group in the one or more SIB type groups comprises a plurality of SIB types.
15. The terminal device according to claim 13 , wherein the update information of the one or more SIB types is a part of the short message in the paging DCI.
16. The terminal device according to claim 13 , wherein the processor is further configured to determine a manner of indicating the update information of the one or more SIB types in the paging DCI according to a predefined standard or according to notification of a network device through broadcast of system information or a radio resource control signaling.
