Abstract: A cell selection or reselection method includes that a terminal device obtains first information that corresponds to a first cell and that is not specific to a frequency band or a frequency. When a first condition that corresponds to the first information and that is used to determine whether the terminal device can access the first cell is not met, the terminal device is allowed to select or reselect a cell on a same frequency as the first cell.

Abstract: A terminal device obtains a first group of parameters corresponding to a first mode. A network device obtains a second group of parameters corresponding to the first mode, where the first group of parameters correspond to the second group of parameters. When a compatibility problem exists between the terminal device and the network device, the terminal device initiates initial access to the network device based on the first group of parameters, and the network device accepts, based on the second group of parameters, the initial access initiated by the terminal device.

Abstract: This application provides a communication method and a communication apparatus. The method includes: receiving first DCI from a network device; and determining, based on the first DCI, that first data scheduled by the first DCI includes a first SIB 1, where the first SIB 1 includes information related to network access in a first operation mode. The first DCI includes first indication information, and the first indication information indicates that the first data includes the first SIB 1. Alternatively, one or more of the following information associated with the first DCI is different from that associated with second DCI: scrambling information, DCI format information, time domain or frequency domain resource information, the second DCI is used to schedule a second SIB 1, and the second SIB 1 includes information related to network access in a second operation mode.
