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…

Different Tasks and States of RRC Protocol in LTE-EUTRAN The RRC protocol for EUTRAN is responsible for the basic configuration of the radio protocol stack. But one should note, that…

Layer and channel relationship in LTE The radio interface is composed of different layers in order to set up, reconfigure and release the radio bearer services. The protocol layer is…

Synchronization & BCH for TDD Frame in LTE Synchronization: Purpose: Achieves alignment between the base station (eNodeB) and User Equipment (UE) in LTE Time-Division Duplex (TDD) frames. Methods: Time synchronization…

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: •…

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…

Establishment and Maintenance of the RRC connection in LTE In Long-Term Evolution (LTE), the Radio Resource Control (RRC) connection plays a crucial role in establishing and maintaining the communication link…

In LTE (Long-Term Evolution), handover measurements are crucial for ensuring seamless mobility as User Equipment (UE) moves across different cells within the network. These measurements assist in deciding when and…

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…

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…
