1. A method for wireless communication, comprising: receiving, by a user equipment (UE), a message transmitted from a base station, wherein the message comprises a carrier frequency list comprising a frequency for carrying traffic within a channel bandwidth that is limited to 200 zHz; operating, by the UE, at the carrier frequency indicated by the message, wherein the carrier frequency is determined based on a carrier frequency index for the carrier frequency, wherein the carrier frequency index is associated with an indentification of the UE and a number of carrier frequencies in the carrier frequency list; evening, by the UE, a parameter that includes information for a transmission power of a narrowband reference signal (NRS) of the carrier frequency, wherein the parameter comprises an offset value indicating a difference of the transmission power of the NRS of the carrier frequency indicated by the information relative to a transmission power of an NRS of an anchor carrier frequency, wherein the anchor carrier frequency is configured to carry a broadcast channel or a synchronization channel; determining, by the UE, an energy per resource element of the narrowband reference signal of the carrier frequency based on the information for the transmission power of the NRS; and performing, by the UE, a reference signal received power measurement based on the energy per resource element of the NRS.
