## Abstract

Some embodiments of this disclosure include apparatuses and methods for a signaling mechanism for user equipment (UE) assistance feedback in a wireless communication system. At least a radio frequency integrated circuit can be configured to receive a first configuration signal, and transmit a first message comprising a UE assistance feedback, generated based on the first configuration signal, in an uplink (UL) channel. The first message can contain an index of a profile with information on a service requirement, a traffic characteristic, or a combination thereof of a network. A processor, coupled to the radio frequency integrated circuit, can be configured to generate the UE assistance feedback based on the first configuration signal.
