Abstract: aspects of the present application provide methods and devices for a phase tracking reference (pt-rs) scheme for use by a single carrier offset qam (sc-oqam) transmitter and receiver to estimate, and correct, phase errors that occur over the communication link between the sc-oqam transmitter and receiver. a transmitter may set the sign (positive or negative) of pt-rs symbols dynamically allowing the transmitter to better utilize iq interference caused by data symbols and other pt-rs symbols. another aspect of the present disclosure provides a receiver that can estimate phase error due to phase noise without knowing the sign of pt-rs symbol or the sign of iq interference. this type of phase error estimation improves the phase noise estimation performance, and thus may improve the overall block error rate (bler) performance at the receiver.
