Abstract: This application provides a random access method, a terminal, and a network device. The random access method includes: determining, by a terminal, whether a resource used for random access conflicts with a resource used for receiving a downlink signal; and if the resource used for the random access conflicts with the resource used for the downlink signal, preferentially using the conflicting random access resource for receiving the downlink signal but not for the random access.

Abstract: A communication method and an apparatus, the method including generating a demodulation reference signal (DMRS) sequence of a broadcast signal according to a pseudo-random sequence c(m), where the DMRS sequence is related to a quantity NRB of resource blocks (RBs) of the broadcast signal and a quantity nRE of resource elements (REs) occupied by the DMRS sequence in one RB, and mapping the DMRS sequence to one or more symbols.
