FAQ's

What is Carrier Aggregation in LTE technology?

Carrier Aggregation is a special technique to meet LTE-Advanced requirements, supporting wider transmission bandwidths, larger than the 20 MHz bandwidth specified in 3GPP Release 8. Carrier aggregation allows expansion of effective channel bandwidth delivered to a user terminal through concurrent utilization of radio resources across multiple carriers, where the multiple component carriers are aggregated to form a larger overall transmission bandwidth.

What is Sounding Reference Signal (SRS)?

SRS is one of the available UL reference signal used to measure the channel quality over a section of the bandwidth. eNodeB uses this information to perform frequency selective scheduling and link adaptation decisions

What are the differences between FDD-LTE and TDD-LTE?

The major difference lies in the LTE frame structure in both the FDD and TDD versions of the LTE. In FDD there will be pair of frequencies assigned in the downlink and uplink directions and hence transmissions from multiple subscribes can happen at the same time but on different frequencies as mentioned. In TDD, one single frequency will be used at different time instants by multiple subscriber terminals (UEs). Both frame versions of LTE will have 1 ms sub-frame duration and 0.5 ms slot duration.
