The embodiment of this application provides a communication method and device, which includes: determining the length of GP in the time slot according to the communication condition between the network device and the terminal, including downlink communication time period, GP and upstream communication time period, in which the length of GP is variable and the GP is used to isolate downlink communication time period and upstream communication time period. Wireless communication is performed within a time slot, which includes downlink communication during downlink communication period and upstream communication during upstream communication period. The communication status includes at least one of the following: the upstream and downstream switching capability of the terminal, the data block size of the downstream communication, and the timing relationship between the downstream communication and the upstream communication. Thus, the phenomenon of waste of resources is avoided and the efficiency of resource utilization is improved.
