[0083] The wireless communication system 200 corresponds to a heterogeneous network (HetNet). The second network device 203 is a macro node in the heterogeneous network, for example, the second network device 203 is a macro base station (Macro cell). The first network device 202 is a lower power node (LPN) in the heterogeneous network, for example, the first network device 202 is a small base station (small cell), a micro eNB, a home eNB, and the like. The wireless communication system 200 can include a plurality of first network devices 202.

[0084] The second network device 203 provides basic wireless coverage to the mobile terminal 201 within the cell. The coverage area of ​​each first network device 202 is within the coverage area of ​​the second network device 203, and can be used to improve capacity at the boundaries between the coverage areas of the second network device 203.

The mobile terminal 201 can receive communication data services through the second network device 203; or, within the coverage area of ​​the first network device 202, the first network device 202 can provide communication data services.

[0085] This disclosure provides a method for transmitting a wake-up signal. (Refer to...) Figure 3 , Figure 3 This is a method for transmitting a wake-up signal according to an exemplary embodiment, such as... Figure 3 As shown, the method includes steps S301 to S304, specifically:

[0086] In step S301, the mobile terminal 101 determines the frequency domain resource information, which indicates the frequency domain resources used to send the uplink wake-up signal. The uplink wake-up signal is used to wake up the first network device 102.

[0087] In step S302, the mobile terminal 101 sends an uplink wake-up signal to the first network device 102 based on the frequency domain resource information.

[0088] In step S303, the first network device 102 receives the uplink wake-up signal sent by the mobile terminal 101 based on frequency domain resource information.

[0089] In step S304, the first network device 102 performs wake-up according to the uplink wake-up signal.

[0090] In some possible implementations, this embodiment can be applied to homogeneous networks or heterogeneous networks.

[0091] In some possible implementations, the first network device 102 is in a sleep state before receiving an uplink wake-up signal from the mobile terminal 101. Upon receiving the uplink wake-up signal, the first network device 102 wakes up to transmit and receive communication data.

[0092] In some possible implementations, frequency domain resource information is used to indicate a frequency domain location, and the mobile terminal 101 can send an uplink wake-up signal according to the frequency domain location. This frequency domain location can be defined according to a protocol.

[0093] In some possible implementation, when the mobile terminal 101 sends the uplink wake-up signal to the first network device 102 based on the frequency domain resource information in step S302, the uplink wake-up signal can be sent on any time domain resource. Because in this case, the first network device 102 can be in a sleep state for a long time, so that the mobile terminal 101 cannot obtain the synchronization signal and cannot know the corresponding time domain resource. In order to make the first network device 102 be woken up in time, a low-power receiver which is always in an on state is arranged in the first network device 102, and the receiver is used to receive the uplink wake-up signal in real time.

[0094] In the embodiment of the present disclosure, the mobile terminal 101 can send the uplink wake-up signal according to the frequency domain resource indicated by the frequency domain resource information. The first network device 102 performs the wake-up again after receiving the uplink wake-up signal, which can effectively save the energy consumption and can timely restore the transceiving function and perform the data communication with the mobile terminal.

[0095] The embodiment of the present disclosure provides a method for transmitting a wake-up signal. Referring to Figure 4a , Figure 4a A method for transmitting a wake-up signal is shown according to an example embodiment, as shown in Figure 4a , the method includes steps S401a-S406a, and specifically:

[0096] In step S401, the second network device 203 sends first configuration information to the mobile terminal 201, and the first configuration information is used to indicate the frequency domain resource information, and the frequency domain resource information is used to indicate the frequency domain resource for sending the uplink wake-up signal, and the uplink wake-up signal is used to wake up the first network device 202.

[0097] In step S402, the mobile terminal 201 receives the first configuration information from the second network device 203, and the first configuration information is used to indicate the frequency domain resource information.

[0098] In step S403, the mobile terminal 201 determines the frequency domain resource information, and the frequency domain resource information is used to indicate the frequency domain resource for sending the uplink wake-up signal, and the uplink wake-up signal is used to wake up the first network device 202.

[0099] In step S404, the mobile terminal 201 sends the uplink wake-up signal to the first network device 202 based on the frequency domain resource information.

[0100] In step S405, the first network device 202 receives the uplink wake-up signal sent by the mobile terminal 201 based on the frequency domain resource information.

[0101] In step S406, the first network device 202 performs the wake-up according to the uplink wake-up signal.

[0102] In some possible implementation manners, the embodiment can be applied to a heterogeneous network.

[0103] In some possible implementation manners, the first configuration information of the second network device 203 can be respectively sent to the mobile terminal 201 and the first network device 202.

[0104] In the embodiment of the present disclosure, the mobile terminal 101 can obtain the frequency domain resource information according to the first configuration information of the second network device 203, and then perform the sending of the uplink wake-up signal according to the frequency domain resource of the uplink wake-up signal indicated by the frequency domain resource information. The first network device 202 performs the wake-up again when the uplink wake-up signal is received, which can effectively save the energy consumption and timely restore the transceiving function to perform the data communication with the mobile terminal.

[0105] In an embodiment, Figure 4a The method shown is applied to Figure 2 When the heterogeneous network shown is applied, the second network device 203 can send multiple frequency domain resource information to the same mobile terminal 201, and different frequency domain resource information is used to wake up different first network devices 201. Each frequency domain resource information indicates the frequency domain resource used to send the wake-up signal to the corresponding first network device 201. In a possible implementation manner, the same frequency domain resource can correspond to different first network devices 201.

[0106] In an example, the second network device 203 is a macro base station, and the first network device 201 is a small base station. The macro base station manages X small base stations, and the macro base station sends the first configuration information to the mobile terminal 201, the first configuration information including N frequency domain resource information, each frequency domain resource information corresponding to a small base station, different frequency domain resource information corresponding to different small base stations, and each frequency domain resource information indicating the frequency domain resource used to send the wake-up signal to the corresponding small base station.
