IN-PHASE AND QUADRATURE-PHASE TRACKING REFERENCE SIGNAL

Abstract:

The present aspects provide apparatuses, methods, and computer-readable medium for wireless communication at a user equipment (UE), including receiving, from a base station, an in-phase and quadrature-phase tracking reference signal (IQTRS) configured for an estimation of an IQ impairment at the UE; estimating the IQ impairment based on the IQTRS; and compensating for the IQ impairment in a decoding process configured to decode one or more signals received from the base station.
