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). A method and system for managing data transmission in a communication network is provided. During Data Resource Bearer (DRB) creation, network signals to a transmitting node, the data transfer requirement. The network uses a signaling parameter to indicate a large data transfer requirement. Based on the data transfer requirement information collected from the network, the transmitting node determines the type of data format that needs to be used for the data transmission. If the network signals large data transfer requirement, then the transmitting node selects a Subheader format in which the length field of the data format suits the large data transfer requirement. Further, data communication is initiated using the selected Subheader format.

Abstract: Disclosed herein is method and system for hierarchical decoding of data packets in cellular communication network. At first, base station upon receiving data packets computes LLR values and evaluates computed LLR values through first Cyclic Redundancy Check (CRC) to determine successful decoding of data packets. When first CRC is unsuccessful and when SINR is greater than first predefined threshold, base station combines LLR values of intra base stations with computed LLR values for decoding data packets and performs second CRC check to determine if data packets are successfully decoded. The base station combines LLR values of intra base stations and LLR values of inter base stations with computed LLR values for decoding data packets when SINR value of inter base stations is greater than second predefined threshold and when evaluated second CRC is unsuccessful and performs third CRC. The present disclosure increases throughput and reduces latency significantly while decoding packets.
