Abstract
Aspects are provided which allow for a network entity such as a base station to configure odd modulation orders to be applied to downlink or uplink transmissions via signaling between the network entity and the UE. Initially, the network entity transmits a configuration to the UE indicating network support for communications using odd order modulation. Afterwards, the UE transmits, and the network entity receives, data in a signal using the odd order modulation. As a result, improved SPEF, PAPR reduction, and phase noise mitigation associated with odd order modulations may be realized through application of odd order modulations to data transmissions or receptions based on network support being configured for such odd order modulations.
