1. A method for wireless communication, comprising:
transmitting, by a mobile device, a Radio Resource Control, RRC, connection request to a base station, the RRC connection request message indicating a support by the mobile device for a narrowband multi-carrier operation in a licensed spectrum with a bandwidth of 200 KHz;
receiving, by the mobile device, an RRC connection message from the base station in response to the RRC connection request indicating the support for the narrowband multi-carrier operation, the RRC connection message including information that indicates a service carrier frequency selected by the base station for carrying traffic, wherein the information comprises an offset value indicating a difference between a transmission power of a narrowband reference signal of a non-anchor carrier indicated by the information and a transmission power of a narrowband reference signal of an anchor carrier, wherein the anchor carrier is configured to carry a broadcast channel and a synchronization channel and the non-anchor carrier is configured to carry traffic in which no broadcast channel or synchronization signal from the base station is assumed, wherein the information further indicates a transmission power of a narrowband reference signal of the service carrier frequency selected by the base station; and
operating the mobile device at the service carrier frequency indicated by the RRC connection message using a transmission power determined based on the offset value and the transmission power of the narrowband reference signal of the anchor carrier.
