1. A method for decreasing required radio spectrum in a communication system using variable bandwidth, the method comprising:
- dividing radio frequencies of the communication system into a wideband channel radio frequency and narrowband channel radio frequencies; and
communicating user data using both the wideband channel radio frequency and the narrowband channel radio frequencies,wherein the narrowband channel radio frequencies are used for communicating user data when a device involved in the communication is located in cell boundary regions, and wherein the wideband channel radio frequency is used for communicating user data when a device involved in the communication is not located in a cell boundary region.

Abstract
A method, device, and system that use narrowband channels to provide higher re-use without multiplying the operator spectrum requirement. If a communication system supports variable carrier bandwidth channels, the narrow channel capacity can be divided among adjacent cells to provide higher re-use.
