Embodiments herein provides a method and apparatus for data communication in an OFDM system. The method comprising receiving by a second OFDM apparatus a plurality of parameters, a signal comprising data and at least one of a Reference Signal (RS) and a message from a first OFDM apparatus. The plurality of parameters comprises at least one of a numerology of the first apparatus, a numerology of the second apparatus, a ratio of numerology of the first apparatus to the second apparatus and a measurement window. The method includes filtering a desired band comprising the at least one of the RS and the message from the received signal, removing a cyclic prefix from the filtered signal, and decoding at least one of the RS and the message from the signal with adjusting a circular shift in the set of symbols based on the plurality of parameters.

Method and apparatus for data communication in orthogonal frequency division multiplexing system

Accordingly, the invention provides a method and apparatus for managing communication operations in an Orthogonal Frequency Division Multiplexing (OFDM) system. Further the method includes generating, by a first OFDM apparatus (), a signal comprising data and at least one of a Reference Signal (RS) and a message, the signal is generated by repeating the at least one of the RS and the message over a set of OFDM symbols using a resource mapper, performing an Inverse Fourier Transform operation (IFFT) according to a numerology of a first OFDM apparatus, adding a Cyclic Prefix (CP) to the data, and adding a block CP to the at least one of the repeated RS and the message. Further, the method includes transmitting, by the first OFDM apparatus (), the signal to a second OFDM apparatus ().
