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.

Abstract: A CSI-RS indicating method and a device are provided. The method includes: receiving paging DCI, wherein the paging DCI indicates one or more of the following: whether to transmit CSI-RS; whether to update CSI-RS configuration information; and whether to update system information, the system information including the CSI-RS configuration information. In the embodiment of the present disclosure, a terminal can determine whether to transmit CSI-RS or whether to update CSI-RS configuration information according to the received paging DCI; in a case that the paging DCI indicates to transmit CSI-RS, the terminal receives the CSI-RS; and in a case that the paging DCI indicates to update the CSI-RS configuration information, the terminal acquires updated CSI-RS configuration information and receives CSI-RS according to the updated CSI-RS configuration information.
