Abstract: Embodiments of this application provide a communication method, a communication apparatus, and a communication system.

Abstract: A data transmission method and apparatus are disclosed in the present invention. The method includes: determining whether there is to-be-scheduled user equipment in a first transmission time interval, where a frame structure used in the first transmission time interval includes a data scheduling area and a control information scheduling area; when it is determined that there is to-be-scheduled user equipment in the first transmission time interval, determining whether there is any idle resource in the control information scheduling area; and after it is determined that there is still an idle resource in the control information scheduling area, sending indication information to the to-be-scheduled user equipment, where the indication information is used to instruct the user equipment to send uplink data on an idle resource of the uplink control information scheduling area and/or obtain downlink data on an idle resource of the downlink control information scheduling area.

Abstract: A method includes: after a user equipment UE accesses a first-standard network, acquiring, by a control unit, first resource status information of the first-standard network and second resource status information of at least one second-standard network having an overlapping area with the first-standard network, where the first-standard network or the second-standard network includes a wireless fidelity WiFi network; and determining, by the control unit according to the first resource status information and the second resource status information, whether offload processing needs to be performed for the UE.
