What is PHY?

PHY, short for physical layer, is the lowest layer in the OSI model. It defines the hardware specifications for transmitting and receiving data over a physical medium. This includes aspects like voltage levels, data rates, modulation techniques, and physical connectors. It is responsible for the actual transmission of raw data bits over a communication channel, facilitating the interface between a device and the transmission medium.

RLC

Radio Link Control (RLC) is a layer 2 protocol that works closely with the PHY layer in wireless communication systems like LTE and NR. It provides services like segmentation, reassembly, and error correction.

RRC

Radio Resource Control (RRC) is a layer 3 protocol that controls the radio resources and connection establishment, release, and maintenance for user equipment. It complements the PHY layer by configuring its parameters.

PDCP

Packet Data Convergence Protocol (PDCP) is a layer 2 protocol providing header compression, security, and integrity protection to IP packets. It is above PHY layer.
