Communication method and communications device
This application provides a communication method and a communications device. The method includes: after a terminal sends a first preamble to a network device, determining, by both the terminal and the network device, a scramble value of a first RAR according to an ith time unit, a first frequency domain resource, and a maximum RAR time window length, where the ith time unit is a first time unit corresponding to a first time domain resource, the maximum time window length includes M time units, and M equals to an integer multiple of a quantity of time units included in a system frame of each system parameter in a plurality of system parameters for communication between the terminal and the network device. Therefore, RAR detection accuracy may be improved.
