How Data Transmission in UL in LTE?

In UL, the UE has no dedicated resources to transmit directly when new data arrived in the buffer from higher layer.  It requests resources to transmit them.  It receives radio

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 for the BCCH

How DL Channel works in LTE?

The PDCCH, Physical Downlink Control Channel, allocates the DL and UL resources. There is one PDCCH per sub-frame.   It helps the UE retrieve the transport blocks from the PDSCH:

LTE : Data Transmission in DL

The data in DL are sent on the PDSCH  A minimum of 2 RBs are allocated by the eNodeBs.  A RB is 12 sub-carriers on a slot (7 symbols).  The

UE categories in LTE

These UE categories are often referred to as UE classes. The low end UE does not support MIMO but the high end UE will support 4×4 MIMO Whatever category a

What Interference Rejection Combining in LTE

The concept of Interference Rejection Combining (IRC) is to regenerate the transmitted signal based on the estimated data from the previous receptions, emulate the distortion occurring from the multi-path channels

Operating Frequency Band and RSRP for LTE

Choosing which frequency band to operate a LTE network is one of the most critical decision. Operator has to make when it comes to capacity planning. The frequency propagation and
