Radio Protocol Architecture in LTE The EUTRAN radio protocol model specifies the protocols terminated between UE and eNB. The protocol stack follows the standard guidelines for radio protocol architectures (ITU-R M1035) and is thus quite similar to the WCDMA protocol stack of UMTS. The protocol stack defines three layers: the physical layer (layer 1), data … Read more
Layer and channel relationship in LTE The radio interface is composed of different layers in order to set up, reconfigure and release the radio bearer services. The protocol layer is composed of physical layer (layer 1), data link layer (layer2), and the network layer (layer3). In the E-UTRAN layer 2 is divided into two sub-layers: … Read more
Packet Data Convergence Protocol (PDCP) in LTE What is pdcp in lte: – PDCP means Packet Data Convergence Protocol means it convert data at protocol level let’s check its function at user plane and control plane in details. The main services provided by the Packet Data Convergence Protocol (PDCP) are: IP header compression and decompression … Read more
