EPS – The Network Architecture

Nodes Description Evolved UTRAN The evolved RAN for LTE consists of a single node, i.e., the eNodeB (eNB) that interfaces with the UE.  The eNB hosts the PHYsical (PHY), Medium Access Control (MAC), Radio Link Control (RLC), and Packet Data Control Protocol (PDCP) layers that include the functionality of user-plane header-compression …

Orthogonal Frequency-Division Multiple Access (OFDMA)

With Orthogonal Frequency-Division Multiple Access (OFDMA) muliple access is achieved by assigning subsets of sub-carriers to individual users. This allows simultaneous low data rate transmission from several users.OFDMA simultaneously supports multiple users by assigning them specific subchannels for intervals of time.So in short, Each terminal occupies a subset of sub-carriers …
