Abstract
Some wireless communications systems provide communications between user equipments (UEs) and non-terrestrial networks (NTNs). An NTN may include one or more NTN nodes (e.g., satellites). When communicating with low Earth orbit (LEO) satellites, a signal received by a UE may exhibit a time-varying carrier frequency shift or Doppler shift. Some examples of the techniques described herein may address the effects of NTN Doppler on front end processing. Some examples of the techniques described herein may use a Doppler-dependent droop compensation filter after Doppler compensation using a rotator. In some approaches, Doppler-independent droop compensation may be performed. For example, a droop compensation filter may be designed for wider bandwidth that addresses a Doppler shift. A filter for jammer rejection may be utilized based on the Doppler shift or based on an NTN or terrestrial network (TN) scenario.
