Abstract: Embodiments of the present application relate to the field of wireless communications technologies, and provides a communication method. The method includes: in response to detecting that a carrier is idle, determining, by a base station, a first subframe that is used for sending downlink synchronization signals, where the downlink synchronization signals include a primary synchronization signal and a secondary synchronization signal; and sending the downlink synchronization signals to a terminal in the first subframe based on a subframe number of the first subframe and a first correspondence. Correspondingly, the terminal performs detection of the synchronization signals, and performs frame timing based on at least location information of the secondary synchronization signal in the first subframe and the first correspondence. In this way, downlink synchronization in an LBT mechanism can be implemented.

Abstract: Embodiments of the present disclosure provide a data transmission method and apparatus. The method includes: obtaining, by a base station, at least one clear channel assessment (CCA) detection threshold; determining a current CCA detection threshold from the at least one CCA detection threshold; determining transmit power of to-be-sent data based on the current CCA detection threshold; and sending the to-be-sent data to a target terminal based on the transmit power. In this way, a CCA detection threshold is flexibly selected, the transmit power is adaptively adjusted, and a probability of space division multiplexing and spectrum usage efficiency are improved, thereby increasing a system capacity and avoiding interference between systems.
