LTE RADIO PROTOCOLS

LTE RADIO PROTOCOL ARCHITECTURE ACCESS STRATUM

LTE network can be divided into control plane which is responsible for managing the transport and user plane which is responsible for transporting user traffic.

USER PLANE PROTOCOLS: this shows the protocol stacks for the user plane where PDCP,RLC,MAC and PHY sublayers perform functions like header compression, ciphering, scheduling.

CONTROL PLANE PROTOCOLS: PDCP sublayer perfoms ciphering and integrity protection.

RLC,MAC and PHY sublayers perform the same function as in the user plane.

RRC performs functions like system information broadcast, paging, RRC connection management , mobility control and UE measurement reporting and control.
