[0145] Such as Figure 5 As shown, the embodiment of the present invention provides a method for sending indication information, including:
[0146] Step 51, determine a control channel according to predetermined time domain resources and frequency domain resources;
[0147] Specifically, firstly, a time domain resource is determined, in which the first time domain resource for bearing the control channel is determined; a frequency domain resource is determined, in which the frequency domain resource is determined for bearing the control channel first frequency domain resources;
[0148] Wherein, at least one minimum time-domain scheduling unit is determined as the time-domain resource; and at least one preset carrier is determined as the frequency-domain resource.
[0149] Step 52, sending indication information in the control channel, where the indication information is used to indicate the use of preset time-frequency resources before the control channel;
[0150] The co...

[0156]In the second embodiment of the present invention, a method for sending indication information is provided, the method includes all the steps in the above first embodiment and the implementation of each step; and further, determining the time domain resource position where the control channel is located Ways include:
[0157] Method 1: If Figure 6 , Figure 8 As shown, in at least one minimum time-domain scheduling unit, the first n1 available OFDM symbols for downlink transmission of each time-domain resource for downlink transmission are used as the first time domain for bearing the control channel 61 Resources, where n1 is a positive integer greater than or equal to 1.
[0158] Wherein, the initial n1 available OFDM symbols for downlink transmission of the time domain resources used for downlink transmission in the minimum time domain scheduling unit may be the multiplexed traditional control channel, and the traditional control channel may be shared by the cell A...

[0248] The embodiment of the present invention also provides a device for sending indication information, including:
[0249] A determining module, configured to determine a control channel according to predetermined time domain resources and frequency domain resources;
[0250] A sending module, configured to send indication information in the control channel, where the indication information is used to indicate usage of preset time-frequency resources before the control channel.
[0251] It should be noted that the embodiment of the device is a device corresponding to the method described in the first and second embodiments above, and all the implementation methods in the above method embodiment are applicable to the embodiment of the device, and can also achieve the same technical effect.
