Abstract: Embodiments herein provide a method and system for managing Grant-free data transmission in a radio communication network. The proposed method includes composing, by a Base Station (BS), a Select Signal (SS) for a transceiver device, where the SS is configured to control a grant-free data transmission from the transceiver device. Further, the proposed method includes transmitting, by the BS, the SS to the transceiver device. Further, the proposed method includes receiving, by a transceiver device, the SS from the BS. Further, the proposed method includes decoding, by the transceiver device, the SS and furthermore, the proposed method includes controlling, by the transceiver device, a data transmission by one of activating the grant-free data transmission from the transceiver device in response to successful decoding of the SS, and deactivating the grant-free data transmission from the transceiver device in response to unsuccessful decoding of the SS.

Abstract: Embodiments herein provide an OFDMA method for performing OFDM based communication in a wireless communication system. The OFDMA method includes splitting a carrier bandwidth into a number of subbands and modulating resource units in each of the subbands with data symbols in a parallel manner Further, multiplexing the resource units by transforming each of the modulated resource units through a plurality of unitary transformations at a stage. Further, generating an output by performing a parallel to serial conversion of the transformed resource units. Further, the OFDMA method includes generating an OFDM signal by multiplexing an output from at least one of the previous stage to another stage by transforming the output through a unitary transformation for a defined number of times. Furthermore, the OFDMA method includes transmitting the OFDM signal over a wireless channel in the wireless network system.

Abstract: The embodiments herein provide a method for In Band Full Duplex (IBFD) communication in a radio network including at least one IBFD node, at least one first non-IBFD User Equipment (UE) and at least one second non-IBFD UE. The method includes transmitting by the at least one IBFD node a first signal to the at least one first non-IBFD UE over a forward channel, and receiving by the at least one IBFD node a second signal from the at least one second non-IBFD UE over the same forward channel simultaneously, where the second signal includes at least one of a pilot signal, Channel State Information (CSI), and control information, where the forward channel is orthogonal to a reverse channel in at least one of time, frequency, space, and code.
