Abstract:

A method for encryption in a wireless communication system includes encrypting, at a base station, data of a physical layer control channel using at least one of a control channel type, a radio resource aggregation level of the control channel, a radio resource index of the control channel, or a subcarrier frequency of the control channel; and transmitting the encrypted data to a user equipment (UE), where the UE is in a cell of the base station.
