A method and a user equipment for controlling multiple communication systems to implement communication are disclosed. The method includes: when a long term evolution LTE system module in a UE is about to enter a discontinuous reception DRX sleep state or to temporarily stop data transmission, sending, by the LTE system module, first indication information to another system module in the UE, where the first indication information is used for indicating, to the other system module, that the LTE system module enters the DRX sleep state and at least part of time during which the LTE system module is in the DRX sleep state, or the first indication information is used for indicating that the other system module is capable of performing data transmission and time during which the other system module is capable of performing data transmission. |

1. A method for controlling multiple communication systems in a user equipment (UE) to implement communication, the UE comprising first communication circuitry configured to operate the UE in a long term evolution (LTE) communication system and second communication circuitry configured to operate the UE in a second communication system, the method comprising:
in response to detecting, at the UE, an occurrence of a first triggering condition, sending, by the first communication circuitry, first indication information to the second communication circuitry, wherein the triggering condition comprises at least one of:
expiration of a discontinuous reception DRX inactivity timer of the UE;after the UE receives a DRX media access control MAC information element;the UE not receiving scheduling information on a physical downlink control channel (PDCCH) within a timing period of an on-duration timer of the UE;the first communication circuitry executing only one hybrid automatic repeat request (HARQ) process and detecting PDCCH scheduling information; orafter periodic measurement of the first communication circuitry in a DRX sleep state is finished; wherein the first communication circuitry and the second communication circuitry operate on different frequency bands; and the first indication information is used for indicating, to the second communication circuitry, at least one of:
that the first communication circuitry enters the DRX sleep state and at least part of a time during which the first communication circuitry is in the sleep state within a current DRX period; orthat the second communication circuitry is capable of performing data transmission and a time during which the second communication circuitry is capable of performing data transmission; wherein the method further comprises: after sending the first indication information to the second communication circuitry, sending, by the first communication circuitry, second indication information to the second communication circuitry, wherein the second indication information is used for instructing the second communication circuitry to stop data transmission; wherein the second indication information is sent to the second communication circuitry in response to a second triggering condition, wherein the second triggering condition comprises at least one of:
when periodic measurement time of the LTE system module in the DRX sleep state is about to expire;when current time is in a short DRX period, sending the second indication information to the second communication circuitry before a current subframe number satisfies: [(SFN×10)+current subframe number] mod(length of the short DRX period)=(drxStartOffset) mod(length of the short DRX period); orwhen current time is in a long DRX period, sending the second indication information to the second communication circuitry before a current subframe number satisfies: [(SFN×10)+current subframe number] mod(length of the long DRX period)=drxStartOffset; wherein the SFN is a current system frame number, and the drxStartOffset is used for indicating a subframe at which the on-duration timer of the UE is started within a DRX period. |
