Description

BACKGROUND 1. Technical field The present disclosure relates to an loT device and its communication with a node, for example, a base station or an intermediate node connected to a base station. 2. Description of the Related Art The Internet of things (IoT) market is a major source of revenue for future wireless technology and is a steadily growing market. Building, commercial, health, agriculture, infrastructure, and industries are some of the key sectors targeted by the loT market. Studying the functionality of segmentation in the MAC is of importance to overcome cases where a transport block (TB) size provided by physical layer (PHY) may not be able to accommodate one data packet from upper layer(s). The 3rd Generation Partnership Project (3GPP) works at technical specifications for the next generation cellular technology, which is also called fifth generation (5G) including "New Radio" (NR) radio access technology (RAT), which operates in frequency ranges up to 100 GHz. Integration of ambient loT (A-loT) devices in communication networks, particularly, 5G and future technologies, is an important demanding task, particularly, since A-loT devices lack RRC states and ARQ and HARQ transmission protocols that ensure reliable data delivery, A-loT devices have limited power available resulting in reduced time periods of communication capability and A-loT devices are configured with specifically designed new operation states.
