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

Transmit Diversity & Receive Diversity

Transmit Diversity MISO = Multiple Input Single Output Principle More complex than SISO. 2 or more transmitters and one receiver. MISO is more commonly referred to as transmit diversity. The

LTE Downlink Logical Channel

Paging Control Channel(PCCH) A downlink channel that transfers paging information and system information change notifications. This channel isused for paging when the network does not know the location cell of

Intra E-UTRAN Handover in LTE

The UE is RRC connected. During the HO: The radio link is released from the eNodeB 1 and re-established on the eNodeB 2 The Control plane is switched to the

MIMO Single User for LTE

SU-MIMO = Single User MIMO It is the most common form of MIMO. Each user is served by only one BS and it occupies the resource exclusively, including time, frequency.

Radio Bearer in LTE

There are 2 types of Radio Bearers (RB) in LTE:  To carry signaling. There are called the SRB (Signaling Radio Bearer) To carry user data. There are associated with an

What is EPS Bearer in 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 virtual connection is

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
