Method of monitoring RAR, method of sending RAR, devices thereof and system

摘要

A method of monitoring a Random Access Response (RAR), a method of sending a RAR, devices thereof and a system are provided. The method includes: sending a random access preamble to a base station; monitoring a RAR sent by the base station, at a time position of a downlink beam corresponding to the random access preamble. Since the RAR only needs to be monitored at the time position of the downlink beam corresponding to the random access preamble, the power consumption of the user terminal may be reduced.
