Title: RANDOM ACCESS METHOD AND APPARATUS
Abstract:
Provided are a random access method and apparatus. The method comprises: a terminal device continuously sending a random access signal to a network device at least once; the terminal device detecting, at a random access response window corresponding to continuous sending of the random access signal multiple times, a random access response sent by the network device, wherein the continuous sending of the random access signal multiple times comprises the continuous sending of the random signal at least once; and if the random access response sent by the network device is not detected, at the end of the random access response window, by the terminal device, the terminal device continuing to send the subsequent random access signals to the network device. The present invention can reduce the time delay of random access.
