Radio Link Control RLC in LTE

Here i write about Radio Link Control -RLC in LTE in a simple word. The RLC layer is located between the PDCP ( the “top” layer) layer and MAC layer

LTE Layer 2 user plane protocol stack in detail

LTE user Layer 2 Protocol stack-the plan is composed of three substrates, as shown in the figure. Packet layer packet data convergence Protocol (PDCP) : this layer processes messages resource

S1 and X2 Bandwidth Dimensioning Procedure

The figure below denotes the location of the X2 and S1 link with respect to the other network components within the LTE network. In general, the traffic on S1 interface

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

Physical Channel Types of LTE

The physical layer uses resource blocks to transmit binary coded information in QPKS, 16QAM or 64QAM or OOK modulation form. Physical channels determine how data is processed and then mapped

How to LTE Radio Air Interface?

The state-of-the-art design of the LTE air interface is characterised by OFDMA (DL) and SC-FDMA (UL) together with MIMO. The downlink modulation is based on OFDMA (Orthogonal Frequency Division Multiple
