Different Categories of UE in LTE

Categories of UE in LTE is divided by its function which is as per below. Functionality: eNB obtains the UE radio capabilities via: • The S1AP initial setup request message

Handover Measurements in LTE

Measurements to be performed by a UE for intra/inter-frequency mobility are controlled by e-UTRAN, using broadcast or dedicated control. If the frequency center of the measured cell is the same

How Synchronization Channel Works in LTE?

After the power on, the UE knows:  the UE category and capability. the preferred PLMN. the carriers. The UE needs to know: The frame synchronization to be able to decode

Synchronization & BCH for TDD Frame in LTE

The Primary synchronization signal (PSS): is placed at the third symbol in subframes #1 and #6. The secondary synchronization signal (SSS): is placed at the last symbol in subframes #0

Random Access Procedure in LTE

When the UE has obtained system information, it has to request an RRCconnection. Like it has no dedicated resources, the UE requests the connection using the Random Access Procedure using

Step of RRC Connection Setup in LTE

When the UE is powered up, it has to be RRC connected to be able to exchange data and signaling with the network. After the RRC connection, the Initial network

State of RRC in LTE

RRC uses the following states: RRC_Idle: •The UE is not connected. There is no radio link. •The network knows that the UE is present on the network and is able

Which Cell Parameters needs to Obtain in LTE?

To provide the most critical information to the UEs, the eNodeB uses the BCH channel The information is sent on pre-defined time-frequency resources. This information is organized into different information

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
