Abstract:
1. A method for a terminal including a first physical (PHY)/media access control (MAC) layer and a second PHY/MAC layer to generate an authorization key, the method comprising: performing a first network entry process to a base station through the first PHY/MAC layer; and performing a second network entry process in a frequency overlay to the base station through the second PHY/MAC layer, wherein the second PHY/MAC layer comprises the frequency overlay with regard to the first PHY/MAC layer, wherein the performing of the first network entry process includes acquiring a key for generating an authorization key through an authentication process according to an authentication method negotiated with the base station, and generating a first authorization key through the key for generating the authorization key, and wherein the performing of the second network entry process in the frequency overlay includes generating a second authorization key by using the key, which is acquired through the authentication process in the performing of the first network entry process, without performing further authentication process.
