The AP (110) comprises a processing circuitry (111) configured to generate a nonce and a communication interface (113) configured to transmit a first message to the non-AP station (120). The first message (202) comprises the nonce. In response to receiving a second message from the non-AP station (120), the processing circuitry (111) is further configured to encrypt information about one or more policies. The information about the one or more policies identifies one or more policies to be applied by the non-AP station (120). The communication interface (113) is further configured to transmit a third message to the non-AP station (120). The third message comprises the encrypted information about the one or more policies.
Embodiments of this application disclose a communication method and a communication apparatus, to reduce power consumption of a terminal device and implement low-power positioning on the terminal device. The method in embodiments of this application includes: A terminal device receives first information from an access network device, where the first information is for configuring the terminal device to enter a first mode, and the first information is carried in an RRC release message or an RRC reconfiguration message. The terminal device enters the first mode based on the first information. When the terminal device is in the first mode, the terminal device does not perform at least one of the following: The terminal device monitors a paging message; the terminal device searches for at least one of the following: a synchronization signal block SSB or a system information block SIB1 message; or the terminal device measures an SSB.
