LTE

Why LTE Require in Telecom ?

Higher data rates: Obviously this is a general requirement requested from any new system. Quality of service, Lower delay: To enable true convergence between real-time and non-real-time

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

LTE Link Budget and Coverage Planning

Here I write on LTE RF link budget basic but important topics and criteria to remember for coverage planning for LTE. Let’s start topics. Why Link Budget

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 the transmission time. This is performed

DL scheduler in LTE

The DL scheduler is spit into 3 functional parts: 1.The Static Scheduler: Which assigns a fixed amount of Transport Blocks as well as PDCCH and PDSCH resources

Packet-Switched Radio Interface in LTE

LTE has been designed as a completely packet-oriented multi service system, without the reliance on circuit-switched connection-oriented protocols prevalent in its predecessors. In LTE, this philosophy 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

How CQI, PMI and RI reporting by UE in LTE?

The UE is requested to send either periodic or a periodic reports concerning • Rank indication (RI) Reports are applicable for closed- and open-loop spatial multiplexing. In

Modulation and TB size

A 5-bit “modulation and coding scheme” yields the modulation order, i.e. QPSK, 16QAM or 64QAM. Implicitly the coding rate is given by a combination of the number
