Abstract: 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.

Abstract: Systems, methods, and apparatuses can provide or obtain scheduling information for a system information block type1-bandwidth reduced (SIB1-BR) without obtaining a master information block during handover. A user equipment (UE) can identify SIB1-BR scheduling information in a radio resource control connection (RRC) reconfiguration message. The UE can determine scheduling of an SIB1-BR for a target cell based on the RRC reconfiguration message, and process the SIB1-BR received from the target cell during the determined scheduling.
