Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as long-term evolution (LTE). Methods and devices are provided for detecting a synchronized primary synchronization signal (PSS) sequence in a wireless network is provided. A device receives a synchronization signal including a PSS sequence. The device determines a plurality of peak correlation values by correlating a plurality of predefined PSS sequences with time-shifted variants of the received synchronization signal. The device detects the synchronized PSS sequence from the plurality of predefined PSS sequences by analyzing the plurality of peak correlation values using at least one of probability detection values, a sliding window method, weight assignments, and a rewarding-based method.

Abstract: Embodiments herein provide a method for transmitting downlink control information to a User Equipment (UE) in a wireless communication system. The method includes segmenting a plurality of Aggregation Levels (ALs) across multiple bandwidth parts (BWPs) in a Physical Downlink Control Channel (PDCCH). Further, the method includes transmitting the plurality of segmented aggregation levels across multiple BWPs to one or more UEs. The segmented plurality of ALs comprises multiple combinations of ALs across multiple BWPs. The proposed method includes narrowing down the search space by signaling to the UE explicitly or implicitly the AL resources that the UE has to monitor to perform the decoding of the PDCCH. In some embodiments, the length of the control information formats is modified such that the UE needs to perform a minimum number of blind decoding attempts.
