S1 interface – A Single Interface between LTE RAN and evolved packet core

The S1 interface is the interface between the LTE RAN and evolved packet core. S1 interface protocol stack is described in Figure. S1 performs the following functions: S1-UP (user plane) S1-CP (control plane) LTE S1-UP (user plane) The S1 user…

LTE Possible Dimensioning Concepts

•„All-Average“ –The backhaul connection shall support the aggregated average capacity of all cells. The average capacity is determined under realistic air interface conditions and multiple users per cell. – •„All-Average/Single-Peak“ –The backhaul connection shall support the aggregated average capacity of…

WCDMA Iu PS Interface

Here I write about Iu PS Interface in WCDMA. WCDMA Protocol Structure for Iu PS The Iu PS protocol structure is represented in below image. Again, a common ATM transport is applied for both User and Control Plane. Also the…

What is Margin of Interference in LTE?

Margin sites intrusive noise levels due to an increase can be considered as If sites were spaced closer together than position using the same frequency The thermal noise floor. In other words, the system is interference limited as Opposed to…

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 similar to the WCDMA protocol stack of UMTS. The protocol…
