Flexible spectrum support in cellular wireless communications
First Claim
1. A base station for a cellular communications network, comprising:
- at least one processor; and
memory comprising instructions executable by the at least one processor whereby the base station is operable to;
transmit a non-standardized bandwidth carrier;
transmit information that identifies a standardized bandwidth; and
transmit additional information that, together with the information that identifies the standardized bandwidth, defines a non-standardized bandwidth of the non-standardized bandwidth carrier, where the additional information defines an asymmetric bandwidth adjustment of the standardized bandwidth to provide the non-standardized bandwidth;
where the non-standardized bandwidth carrier comprises a primary synchronization signal, a secondary synchronization signal, and a Master Information Block, MIB, located in frequency resources at a center of the standardized bandwidth.

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.
