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: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A terminal device receives indication information from a first access network device. The indication information is used to indicate to fall back a capability of the terminal device to a first protocol version. The terminal device communicates, based on the indication information, with the first access network device by using first capability information. A protocol version corresponding to the first capability information is lower than or equal to the first protocol version. In this method, because a network device can explicitly indicate to fall back the capability of the terminal device to the first protocol version, the terminal device can specially reduce the capability, so as to quickly resolve a communication problem caused by incompatibility between the terminal device and the access network device.

Abstract: A communication device receives first indication information from a first network device. The first indication information indicates whether to enable a group receiving function. The first indication information is carried in SI, or the first indication information is indicated by a value of a short message indicator bit field in DCI. Then the communication device determines, based on the first indication information, whether to enable the group receiving function.
