Inventors include Rajesh Girmalla Teli; and Aghil Vinayak Puzhakkal.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: ABSTRACT “METHOD AND APPARATUS FOR PERFORMING CHANNEL ESTIMATION FOR UPLINK DATA IN NB-IOT PHYSICAL LAYER” The present disclosure relates to a method for performing channel estimation for uplink data in NB-IoT physical layer. The method comprises receiving a plurality of uplink data signals from at least one User Equipment (UE). The method further comprises dividing each of the uplink data signals into a plurality of processing blocks. Herein, each processing block of the plurality of processing blocks comprises a plurality of slots, wherein each slot of the plurality of slots comprising a plurality of data symbols, a reference signal symbol and a plurality of reference signal tones. For each processing block, the method further comprises estimating a time offset by determining a first correlation value between the plurality of the reference signal tones within one reference signal symbol and estimating a frequency offset by determining a second correlation value between a plurality of reference signal symbols across the plurality of slots. Eventually, the method comprises performing channel estimation upon estimating the time offset and the frequency offset of all of the plurality of the processing blocks.
