Provided are a wireless communication method, a network device and a terminal device. The method includes: after acquiring a PSI parameter of a terminal device, a first network device determines whether to update policy information of the terminal device, wherein the PSI parameter is used for identifying a part of policy information for the terminal device under a subscribed user. In an implementation of the present disclosure, after acquiring a Policy Section Identifier (PSI) parameter of a terminal device, a first network device directly determines whether to update policy information of the terminal device.

A method of operating a first node to generate a secret key for encrypting wireless transmissions between the first node and a second node. The method comprises receiving a first training signal comprising a plurality of subcarriers from the second node and constructing a matrix from the frequency responses of each of the plurality of subcarriers of the first training signal at the first node. A singular value decomposition of the matrix is computed; and a secret key is derived from one or more singular vectors of the singular value decomposition.
