Communication method and communication device

Provided are a communication method and a communication device, the method comprising: a first device sending first information to an access network device through a core network, the first information being used for instructing the access network device to adjust a wireless air interface scheduling-free moment of a second device according to a first moment, the first moment being a service packet sending moment of the second device; and the access network equipment sends first configuration information to the second device according to the first information, and the first configuration information comprises an air interface scheduling-free time slot resource allocated by the access network equipment for the second device. When the time interval between the service packet sending moment corresponding to the second device and the air interface scheduling moment is large, the air interface scheduling moment corresponding to the second device is adjusted, so that the transmission delay is reduced, and the communication performance is improved.
