Systems, methods, and/or techniques for improving downlink spectrum efficiency may be disclosed. For example, a higher order modulation (HOM) transmission may be provided to a device. The higher order modulation transmission may be configured to be indicated by the network or a device. Additionally, multiple modulation and coding scheme (MCS) tables, transport block size (TBS) tables, and/or channel quality index (CQI) tables may be provided to support the higher order modulation transmission.
