Method and apparatus for receiving system information, method and apparatus for sending system information, and storage medium

1. A method for receiving system information, comprising:

receiving system information (SI) reception indication information sent by a base station;

receiving system information indicated by the SI reception indication information; and

stopping monitoring a physical downlink control channel (PDCCH) in a gap pre-configured by the base station, wherein a user equipment (UE) receives the SI in the gap;

wherein the gap in which the UE receives the SI comprises a first Gap and a second Gap,

a length of the first Gap being an interval from a beginning of the UE stopping monitoring the PDCCH to a start of an SI window; and a length of the second Gap being an interval from an end of the SI window to a beginning of resuming monitoring the PDCCH.

2. The method of claim 1 , after receiving system information indicated by the SI reception indication information, further comprising:

sending a scheduling request (SR) to the base station.

3. The method of claim 2 , after sending a scheduling request (SR) to the base station, further comprising:

sending, in response to detecting an uplink grant (UL grant), an SI acknowledge message on an uplink channel indicated by the UL grant.

4. The method of claim 1 , after receiving system information indicated by the SI reception indication information, further comprising:

initiating a physical random access channel (PRACH) random access process.

5. The method of claim 4 , after initiating a PRACH random access process, further comprising:

sending an SI acknowledge message on a third radio resource control (RRC) message Msg3 of the PRACH random access process.

6. The method of claim 5 , wherein

the SI acknowledge message is an MAC CE message, which contains indication information acknowledging reception of SI;

or, the SI acknowledge message is an MAC sub-header, which contains indication information acknowledging reception of SI;

or, the SI acknowledge message is an RRC message, which contains indication information acknowledging reception of SI.

7. The method of claim 1 , after receiving system information indicated by the SI reception indication information, further comprising:

sending uplink information carrying an SI acknowledge message to the base station.

8. The method of claim 7 , wherein sending uplink information carrying an SI acknowledge message to the base station comprises:

sending a media access control (MAC) control element (CE) message and the uplink information which carry the SI acknowledge message to the base station via UL grant.

9. The method of claim 7 , wherein the SI acknowledge message is determined by means of one of: a new logical channel identity (LCID) in an MAC sub-header, a reserved bit of an existing MAC CE message, or a new LCID in the existing MAC CE message, the new LCID being obtained by redefining or adding a function to an LCID in the existing MAC CE message.

10. A non-transitory computer-readable storage medium storing a computer program which, when executed by a processor, causes the processor to perform the method for receiving system information of claim 1 .

11. A method for sending system information, comprising:

sending system information (SI) reception indication information to a user equipment (UE);

sending system information indicated by the SI reception indication information to the UE; and

stopping sending downlink information in a gap pre-configured by a base station, wherein the user equipment (UE) receives the SI in the gap;

wherein the gap in which the UE receives the SI comprises a first Gap and a second Gap,

a length of the first Gap being an interval from a beginning of stopping monitoring a physical downlink control channel (PDCCH) to a start of an SI window; and a length of the second Gap being an interval from an end of the SI window to a beginning of resuming monitoring the PDCCH.

12. The method of claim 11 , after sending system information indicated by the SI reception indication information to the UE, further comprising:

receiving a scheduling request (SR) sent by the UE.

13. The method of claim 11 , after sending system information indicated by the SI reception indication information to the UE, further comprising:

sending an uplink grant (UL Grant) to schedule uplink information transmission.

14. A non-transitory computer-readable storage medium storing a computer program which, when executed by a processor, causes the processor to perform the method for sending system information of claim 11 .

15. An apparatus for receiving system information, comprising a processor and a memory storing a computer program which, when executed by the processor, causes the processor to perform a method for receiving system information comprising:

receiving system information (SI) reception indication information sent by a base station;

receiving system information indicated by the SI reception indication information; and

stopping monitoring a physical downlink control channel (PDCCH) in a gap pre-configured by the base station, wherein a user equipment (UE) receives the SI in the gap;

wherein the gap in which the UE receives the SI comprises a first Gap and a second Gap,

a length of the first Gap being an interval from a beginning of the UE stopping monitoring the PDCCH to a start of an SI window; and a length of the second Gap being an interval from an end of the SI window to a beginning of resuming monitoring the PDCCH.

16. An apparatus for sending system information, comprising a processor and a memory storing a computer program which, when executed by the processor, causes the processor to perform a method for sending system information comprising:

sending system information (SI) reception indication information to a user equipment (UE);

sending system information indicated by the SI reception indication information to the UE and

stopping sending downlink information in a gap pre-configured by a base station, wherein the user equipment (UE) receives the SI in the gap;

wherein the gap in which the UE receives the SI comprises a first Gap and a second Gap,

a length of the first Gap being an interval from a beginning of stopping monitoring a physical downlink control channel (PDCCH) to a start of an SI window; and a length of the second Gap being an interval from an end of the SI window to a beginning of resuming monitoring the PDCCH.
