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 present invention relates to a method of reducing blind decoding attempts by a User Equipment (UE) in a telecommunication network. The method comprises configuring a Search Space (SS) configuration to the UE. A Base Station (BS) signals one of a subset of Aggregation Levels (ALs) to be monitored based on channel quality of the UE and an associated time period, and a value of multiplication factor (k) and an associated time period. The UE iteratively monitors a Physical Downlink Control Channel (PDCCH) on the ALs signalled by the BS till the UE stops receiving a new configuration. The UE performs one of adopting an original configuration, requesting the BS for a new configuration, utilizing a default configuration or utilizing an original configuration.

Abstract: The present invention relates to a method of signalling in an Integrated Access and Backhaul (IAB) network. The method comprises signalling information related to multiplexing capability and supported modes of operation from the child IAB node to the parent IAB node. An active mode of operation is determined at the child IAB node. The configuration to operate in the active mode of operation is signalled to the child IAB node. Timing Advance (TA) for each active mode of operation, guard information for each active mode of operation are signalled as configuration for the active mode of operation. Further, the method comprises signalling exchanges for fallback from one mode of operation to another at child IAB nodes.
