    Abstract: A terminal device receives a first system information change indication on a WUR link, and/or determines, on the WUR link, that a cell is changed, where the first system information change indication indicates that system information is changed. The terminal device receives the system information on an NR link if the system information is changed, before establishing or restoring a connection on the NR link. If the terminal device determines that the system information is not changed, the terminal device may not need to receive the system information. For example, the terminal device may directly establish or restore the connection on the NR link when the terminal device does not need to receive the system information.

    Abstract: A channel state measurement method includes: in a time period between two consecutive times of reporting of channel state information (CSI) reports, determining, based on a status of a CSI-reference signal (RS) resource on a second frequency domain resource, whether a CSI report includes CSI of the second frequency domain resource; or during reporting of a CSI report, determining whether reporting has been performed for the second frequency domain resource. If CSI of the second frequency domain resource has been reported in a current discontinuous reception (DRX) cycle, a current CSI report does not include CSI of the second frequency domain resource; otherwise, a CSI report that currently needs to be reported needs to include CSI of the second frequency domain resource. Alternatively, a terminal receives and measures a CSI-RS resource provided that the CSI-RS resource is within an active time of any frequency domain resource.

    Abstract: Embodiments of this application disclose a random access method and a terminal, applied to the communication field, to improve uplink coverage in high frequency band communication systems such as 5G and 6G communication systems. The method in embodiments of this application includes: A network device configures a plurality of SULs in one cell, where the plurality of SULs are used to supplement uplink coverage of the cell; the network device sends configuration information of the plurality of SULs to a terminal device; and after receiving the configuration information, the terminal device may select one SUL used for random access from the plurality of SULs based on the configuration information. In embodiments of this application, because the cell includes the plurality of SULs, a requirement that a large quantity of terminals in the cell can access a network can be met, and a success rate of uplink random access by the plurality of terminals is improved. Embodiments of this application further provide a terminal. The terminal is configured to select a first SUL used for random access from a plurality of SULs.
