Process Gain in WCDMA

How Process Gain works in 3G? Process Gain = 10 Log (Chip rate/Bit Rate) Process gain differs for each service. If the service bit rate is greater, the process gain

DL & UL Physical Channel in LTE

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

How Transport Channel Work in LTE?

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

How Many Logical Channel in LTE ?

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 Core technology of 3G: CDMA

Formulated by the European standardization organization 3GPP, the core networkevolves on the basis of GSM/GPRS and can thus be compatible with the existingGSM/GPRS networks. It can be based on the

How Channel Architecture in LTE?

A Logical Channel is defined by the type of information it carries. Logical channels are classified into control and traffic channels. Answer to the question: what is it being transported?

How MAC Protocol Work In LTE?

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

Radio Link Control (RLC) protocol services in LTE

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
