FAQ's

What is Single Carrier FDMA (SC-FDMA or DFTS-OFDM) in LTE Uplink?

The main advantage of SC-FDMA is low Peak-to-Average Power Ratio (PAPR) compared to OFDMA used in LTE downlink. This increases the efficiency of power amplifier and hence increases the battery life.

What is RSSI in Optimization Procedure?

RSSI stands for Received Signal Strength Indication and it is mainly used almost in all the Radio Access Technologies to identify total received power in idle as well as connected/dedicated modes. This helps UE always camped on to the best cell all the time. In case of drop in power measured using RSSI, either UE or network initiates the handover or cell re-selection is carried out.

What is Buffer Status Report?

The Buffer Status reporting procedure is used to provide the serving eNB with information about the amount of data available for transmission in the UL buffers of the UE. It is used, among other inputs, as one of the triggering conditions for UL Scheduler to provide UL scheduling grants to UEs.
