Timing Advance in LTE

Timing advance lte what is timing advance in lte: -The eNB measures the required timing advance based on the received UE signal arrival time. It commands the UE to adjust

What is AMC & its Algorithm in LTE

The effective Eb/No and hence the spectral efficiency depend on BLER. However there are QoS requirements which also have to be considered. Taking both into account leads to a target

Spread Spectrum Concept

Dsss – Direct sequence spread spectrum DSSS – Direct Sequence Spread Spectrum is a spread spectrum technology in which original data is expand using PN code randomly to reduce noise

What is EPS Bearer in LTE?

Eps bearer LTE EPS is a connection-oriented transmission network and, as such, it requires the establishment of a “virtual” connection between two endpoints (e.g. a UE and a PDN-GW) This

Difference Between OFDM and FDM in LTE

FDM in LTE Conventional multi-carrier operation as it is used for FDM works simply by selecting a number of center frequencies – one for each carrier to be used. The

What is the difference between LTE and VOLTE?

What is VOLTE:- Volte (voice over lte) refers to voice calls made through a 4G LTE network rather than traditional calls made using csfb (circuit-switched fall-back), a system that switches

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 Process in LTE

The source eNB issues a HANDOVER REQUEST message to the target eNB passing the necessary information to prepare the HO on target side (UE X2 signaling context reference at source

How LTE Network Architecture?

The LTE/EPC architecture is driven by the goal to optimize the system for packet data transfer. Remember that There are no circuit switched components in LTE/EPC. There is a new
