System information transmission method, apparatus and system, and computer-readable storage medium
The present disclosure relates to a system information transmission method, apparatus and system, and a non-transitory computer-readable storage medium, belonging to the field of communication technology. The method can include sending a paging message including indication information, where the indication information is used to indicate other system information which is to be broadcast within a specified period of time. The method can further include broadcasting, within the specified period of time, the other system information indicated by the indication information. This method can reduce the number of system information requests and the frequency of repeatedly broadcasting other system information, thereby reducing waste of radio resources.
1. A system information (SI) transmission method, comprising:
sending a paging message that includes indication information configured to indicate that other SI is to be broadcast in a specified time period, wherein the specified time period comprises at least two SI windows from a SI window after a radio subframe where the paging message is located; and
broadcasting the other SI indicated by the indication information in the specified time period, wherein two continuous SI windows comprise a same system information block (SIB).
2. The method of claim 1 , wherein the indication information comprises multiple identifiers with each identifier of the multiple identifiers corresponding to a unique SIB and being configured to indicate whether the corresponding SIB is to be broadcast in the specified time period.
3. The method of claim 1 , wherein the indication information comprises an identifier that indicates whether all SIBs are to be broadcast in the specified time period.
4. The method of claim 1 , wherein the paging message further comprises an SI modification notification that is configured to send updated SI in a next modification period.
5. The method of claim 1 , wherein the paging message is a short message included in downlink control information (DCI) or a paging message sent on a physical downlink shared channel (PDSCH) indicated by the DCI.
6. The method of claim 1 , further comprising:
receiving an SI request sent by a terminal, the SI request comprising a SIB identifier.
7. A system information (SI) transmission method, comprising:
receiving a paging message including indication information that indicates that other SI is to be broadcast in a specified time period, wherein the specified time period comprises at least two SI windows from a SI window after a radio subframe where the paging message is located; and
receiving the other SI broadcast in the specified time period according to the indication information, wherein two continuous SI windows comprise a same system information block (SIB).
8. The method of claim 7 , wherein the indication information comprises multiple identifiers with each identifier of the multiple identifiers corresponding to a unique SIB and being configured to indicate whether the corresponding SIB is to be broadcast in the specified time period.
9. The method of claim 7 , wherein the indication information comprises an identifier that is configured to indicate whether all SIBs are to be broadcast in the specified time period.
10. The method of claim 7 , wherein the paging message further comprises an SI modification notification that is configured to send updated SI in a next modification period.
11. The method of claim 7 , wherein the paging message is a short message included in downlink control information (DCI) or a paging message sent on a physical downlink shared channel (PDSCH) indicated by the DCI.
12. The method of claim 7 , wherein receiving the other SI broadcast in the specified time period according to the indication information comprises:
reading, when required other SI is not stored, the required other SI from the received other SI, and storing the read required other SI.
13. The method of claim 12 , wherein receiving the other SI broadcast in the specified time period further comprises:
acquiring scheduling information of the other SI from an SIB1;
determining at least one SI window starting from a first SI window after a radio subframe where the paging message is located based on the scheduling information; and
receiving the other SI in an SI window in the determined at least one SI window.
14. The method of claim 7 , wherein receiving the other SI broadcast in the specified time period according to the indication information comprises:
receiving, when required other SI is not stored, the other SI broadcast in the specified time period; and
the method further comprises:
reading the required other SI from the received other SI, and
storing the read required other SI.
15. The method of claim 7 , further comprising:
sending an SI request, the SI request including an SIB identifier.
16. A system information (SI) transmission apparatus, comprising:
a processor;
a transceiver; and
a memory configured to store instructions executable by the processor,
wherein the processor is configured to:
send, through the transceiver, a paging message including indication information that is configured to indicate that other SI is to be broadcast in a specified time period, wherein the specified time period comprises at least two SI windows from a SI window after a radio subframe where the paging message is located; and
broadcast the other SI indicated by the indication information in the specified time period, wherein two continuous SI windows comprise a same system information block (SIB).
17. A system information (SI) transmission apparatus implementing operations of the SI transmission method of claim 7 , comprising:
a processor;
a transceiver;
a memory configured to store instructions executable by the processor;
wherein the processor is configured to:
receive, through the transceiver, a paging message including indication information that is configured to indicate that other SI is to be broadcast in a specified time period, wherein the specified time period comprises at least two SI windows from a SI window after a radio subframe where the paging message is located; and
receive the other SI broadcast in the specified time period according to the indication information, wherein two continuous SI windows comprise a same SIB.
