In Long-Term Evolution (LTE), the channel architecture refers to the organization and allocation of different types of channels used for communication between the User Equipment (UE) and the Evolved NodeB…

How Physical channel of LTE works in UL & DL?A distinction has to made between:  The Physical channel The Physical signal The DL physical channels are: Physical DL Shared Channel…

Transport channels are then mapped on the physical channels which are sent over the air interface A CRC is calculated and appended to each TB. It allows the receiver to…

A transport channel defines how and with what characteristics the information is transmitted. Inherited from the WCDMA, data on the transport channel is organized into “Transport Blocks”, TBs. A Transport…

The following control logical channels have been defined by the 3GPP: BCCH, Broadcast Control Channel, used for the transmission of system control information. A UE needs to decode it before…

The MAC protocol provides the following services: Logical Channel to Transport channel mapping Scheduling: There is no dedicated channel allocated to a UE. Time and frequency resources are dynamically shared…

The Radio Link Control (RLC) protocol provides the following services: Segmentation of SDU according to the size Re-Segmentation of PDU Radio Bearer to logical channel mapping Transfer of data in…
