Abstract: A network access method and a terminal are provided. The network access method performed by the terminal includes receiving a reference signal transmitted by a network-side device. The reference signal includes a first reference signal, or includes a first reference signal and a second reference signal. The first reference signal is an Single-Frequency Network (SFN)-specific reference signal, or the second reference signal is a cell or Transmission Reception Point (cell/TRP)-specific reference signal. The network access method further includes performing an initial access-related operation based on the received reference signal.
