Inter-cell interference coordination (ICIC) in LTE

Inter-cell interference coordination (ICIC) in LTE To aid downlink ICIC Relative narrowband transmission-power indicator A cell can provide this information to neighboring cells, indicating the part of the bandwidth where

How Synchronization Channel Works in LTE?

After the power on, the UE knows:  the UE category and capability. the preferred PLMN. the carriers. The UE needs to know: The frame synchronization to be able to decode

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

How MAC Protocol Work In LTE?

The MAC protocol provides the following services: Logical Channel to Transport channel mapping Scheduling: There is no dedicated channel allocated to a UE. Time and frequency resources are dynamically shared

Resource Element Group in LTE

For the control channel, the radio signaling, the Resource Block is not the adapted unit. The control channels mapped on the Resource Elements Groups (REGs), which represent less radio resources

UL Allocation (SC-FDMA) in LTE

SC-FDMA utilizes single carrier modulation, DFT-spread orthogonal frequency multiplexing, and frequency domain equalization. LTE uses OFDMA on the DL. It allocates DL bandwidth to the user based on resource blocks,

Affects of the Channel in LTE MIMO

To understand the impact of the channel, let’s assume that the base station receiver is facing many challenges in the same MIMO receiver that universal areas, but also must receive

What and How Cell Edge Rate in LTE

Cell Edge Rate in LTE is simple if it’s High then Coverage Low and if It’s Low then Coverage high similar to Frequency selection. Not clear lets understand in detail.
