5G NR PROTOCOL (SDAP PDCP RLC MAC & RRC )

5G, or fifth-generation wireless technology, is the latest and fastest wireless communication technology that is designed to offer faster data speeds, lower latency, and improved network efficiency compared to its predecessor 4G.
To achieve these improvements, 5G uses a variety of protocols, which are sets of rules that govern the way devices communicate with each other and with the network. Here are some of the key protocols used in 5G:
New Radio (NR): This is the air interface protocol used by 5G networks to transmit data wirelessly between devices and the network. NR operates in a higher frequency band than previous wireless technologies, which allows for faster data speeds and more efficient use of available spectrum.
5G Core (5GC): This is the protocol that handles the overall management of the 5G network, including authentication and authorization of devices, routing of data traffic, and maintenance of network services. 5GC is designed to be more flexible and adaptable than previous core network technologies, which allows for more efficient use of network resources.
RRC (Radio Resource Control): RRC is a protocol used in the radio access network (RAN) of wireless networks to control the allocation and release of radio resources. RRC manages the establishment, maintenance, and release of connections between mobile devices and the network. It also manages mobility procedures, such as handovers between different cells or networks, and manages power consumption to ensure efficient use of network resources.
SDAP (Service Data Adaptation Protocol): SDAP is a protocol used in the 5G core network to adapt user data to the requirements of different network functions. It provides a mapping function between the user data and the appropriate network function, such as compression, segmentation, or multiplexing, based on the QoS (Quality of Service) requirements of the user.
PDCP (Packet Data Convergence Protocol): PDCP is a protocol used in wireless networks to provide data compression and encryption for user data. It also handles the segmentation and reassembly of IP packets, as well as the detection and recovery of transmission errors. PDCP operates at the edge of the wireless network, between the user device and the RAN.
RLC (Radio Link Control): RLC is a protocol used in the RAN of wireless networks to provide reliable data transmission over the radio link. It handles the segmentation and reassembly of data packets, as well as the detection and recovery of transmission errors. RLC also provides flow control to ensure that data is transmitted at a rate that can be handled by the receiving device.
MAC (Medium Access Control): MAC is a protocol used in wireless networks to manage access to the radio spectrum. It handles the allocation and release of radio resources, as well as the coordination of transmission between different devices. MAC also provides QoS management to ensure that different types of traffic, such as voice, video, or data, are given appropriate priority based on their requirements.
