The method for receiving system information may include: receiving system information (SI) reception indication information sent by a base station; and receiving system information indicated by the SI reception indication information. ## Claims ### Claim 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. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 2) 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. ### Claim 4 (depends on 1) 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. ### Claim 5 (depends on 4) 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. ### Claim 6 (depends on 5) 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. ### Claim 7 (depends on 1) 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. ### Claim 8 (depends on 7) 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. ### Claim 9 (depends on 7) 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. ### Claim 10 (depends on 1) 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. ### Claim 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. ### Claim 12 (depends on 11) 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. ### Claim 13 (depends on 11) 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. ### Claim 14 (depends on 11) 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. ### Claim 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. ### Claim 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.
