Devices, methods, user equipment (UE), network core devices, gateway devices, evolved node B (eNB), and storage media for UE provisioning are described. In one embodiment, a UE is configured for codec bitrate adaptation via an interface configured to receive a bandwidth indication and a codec awareness indication from an eNB. The UE process the bandwidth indication and identifies, based on the codec awareness indication, a first codec from a plurality of codecs supported by the UE. The UE then configures with the eNB using data encoded with the first codec. This data may, for example, be Voice over Long-Term Evolution (VoLTE) data or other such media data. Selection of the codec or associated codec information may be further based on the codec awareness indication.
