This abstract first appeared for US patent application 20250023685 titled 'METHOD FOR TRACKING REFERENCE SIGNAL (TRS) ENHANCEMENT

==Original Abstract Submitted==

some embodiments include an apparatus, method, and computer program product for tracking reference signal (trs) support of high speed use cases of 5g communications in a single frequency network (sfn), where a user equipment (ue) can measure a doppler offset of a combined signal from two or more transmission reception points (trps) of the 5g communications system. a 5g node b (gnb) node can transmit a periodic, semi-persistent (sp), or aperiodic trs with high measurement density that the ue uses to measure a doppler offset of a combined signal. for example, the gnb can: trigger the aperiodic trs based on a downlink assignment; and/or use lower layer signaling to arrange to transmit a semi-persistent trs or a periodic trs with a reduced periodicity. in some embodiments, the gnb can measure the doppler offset based on an uplink signal, and transmit a trs based on a pre-compensated doppler frequency.
