1. A communication method comprising:generating a first signal;
sending the first signal to a receiver over a first channel that is one of multiple channels in a first band for narrowband communication, and at least one part of the first band is located in a guard band of a radio access network (RAN), and another part of the first band occupies a transmission band of the RAN, wherein the transmission band of the RAN comprising a continuous band of frequencies and does not include the guard band of the RAN; and
preventing mutual signal interference by dedicating a contiguous group of frequencies of the transmission band as a guard interval between a remaining contiguous group of frequencies of the transmission band of the RAN and the first band for narrowband communication,
wherein the guard interval divides the transmission band of the RAN between the remaining contiguous group of frequencies and another contiguous group of frequencies within the first band for narrowband communication.
