INTERPOLATION-BASED CHANNEL STATE INFORMATION (CSI) ENHANCEMENTS IN LONG-TERM EVOLUTION (LTE)

摘要

According to example embodiments, a method for wireless communications by a user equipment (UE) is included. The method generally includes performing channel estimation at a plurality of frequency locations based on reference signals (RS) transmitted from at least one transmission point, computing at least one channel feedback metric for each frequency location, and transmitting the channel feedback metrics to the transmission point. According to certain aspects, a method for wireless communications by a base station (BS) is provided. The BS may receive channel feedback metrics from a UE, calculated at a plurality of frequency locations based on RSs transmitted from the BS. The BS may perform interpolation to determine values for channel feedback metrics for frequency locations between frequency locations of the received channel feedback metrics.
