First Claim
Patent Images
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 a plurality of narrowband channel frequencies; and
communicating user data to a receiving apparatus using both the wideband channel radio frequency and the plurality of narrowband channel frequencies in a wireless communication environment,wherein the wireless communication environment is configured to support the plurality of narrowband channel frequencies for communicating user data when the receiving apparatus involved in the communication is in cell boundary regions, and wherein the wireless communication environment is configured to support the at least one wideband channel frequency when the receiving apparatus involved in communicating user data 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.
