FLEXIBLE SPECTRUM SUPPORT IN CELLULAR WIRELESS COMMUNICATIONS
First Claim
1. A base station for a cellular communications network, comprising:
- a radio subsystem; and
a processing subsystem associated with the radio subsystem and configured to transmit, via the radio subsystem, a non-standardized bandwidth carrier and information that identifies a standardized bandwidth and additional information that, together with the information that identifies the standardized bandwidth, defines a non-standardized bandwidth of the non-standardized bandwidth carrier.

Abstract
Systems and methods for flexible spectrum, or bandwidth, support in a cellular communications network are disclosed. In one embodiment, a base station for a cellular communications network is configured to transmit a non-standardized bandwidth carrier and information that identifies a standardized bandwidth and additional information that, together with the information that identifies the standardized bandwidth, defines a non-standardized bandwidth of the non-standardized bandwidth carrier. In one embodiment, the additional information defines a bandwidth adjustment for the standardized bandwidth that defines the non-standardized bandwidth. In one embodiment, the bandwidth adjustment is a symmetric bandwidth restriction. In another embodiment, the bandwidth adjustment is an asymmetric bandwidth restriction. In yet another embodiment, the bandwidth adjustment is a symmetric bandwidth expansion. In yet another embodiment, the bandwidth adjustment is an asymmetric bandwidth expansion.
