Abstract: This application provides an information transmission method. The method includes: determining, by a first network device, a communication type of the first network device in a second time period; and sending, by the first network device, a signal to a second network device in a first time period through an air interface when the communication type is downlink communication or an idle communication type, where the signal is used to indicate the communication type. The second network device may use the received information on the communication type of the first network device in the second time period to determine its communication type in the second time period to minimize interference between the two network devices. For example, if the communication type of the first network device is downlink in the second time period, the second network device may determine its communication type to be downlink in the second time period.

Abstract: Example methods and apparatus for sending a signal are described. One method includes determining a to-be-sent first signal by a first terminal and determining a first time-frequency resource. Some or all of the first time-frequency resource are second time-frequency resources, and the second time-frequency resource is a time-frequency resource used to send a second signal. The first signal is sent by the first terminal by using the first time-frequency resource, where the first time-frequency resource includes an idle time-frequency resource that is not occupied by the second signal. The first time-frequency resource can also include a common time-frequency resource occupied by the second signal, and the first signal is orthogonal to the second signal in the common time-frequency resource.

Abstract: The present invention discloses a downlink control information sending method and device, and a downlink control information receiving method and device. The sending method includes: sending, by a base station device, downlink control information DCI on a physical downlink control channel PDCCH of a downlink subframe, where the DCI is used to instruct user equipment UE to receive physical downlink shared channel PDSCH information in an uplink subframe; and sending the PDSCH information in the uplink subframe. In this way, the base station can effectively schedule an uplink subframe, and a purpose of transmitting a downlink service by using an uplink subframe is achieved, which not only improves utilization of a wireless spectrum resource corresponding to the uplink subframe, but also effectively diverts load pressure of a wireless spectrum resource corresponding to a downlink subframe. Therefore, overall utilization of wireless spectrum resources of a system is improved.
