A 3GPP LTE protocol enhancement realizes the full benefit of proposed dynamic frequency sharing systems by enhancing current bearer establishment and update provisioning for adaptive Quality of Service (QoS) levels to support Licensed Shared Access (LSA). A User Equipment (UE) comprises a transceiver configured to define an adaptation context, define a default and one or more additional acceptable QoS levels associated with the adaptation context, communicate a request to create or update an adaptive bearer specifying the defined adaptation context and additional acceptable QoS levels, and receive or update spectrum resources for the adaptive bearer. The adaptive bearer may be provisioned according to the communicated request.
