TDD & FDD Carrier Aggregation

- Carrier Aggregation: TDD Carrier Aggregation in single technology（TDD）doubles available capacity and throughput

• DL/UL traffic split in STC network can fit well with 3:1 TDD config.

• TDD Convergence doubles the available capacity.

- Carrier Aggregation: FDD——Carrier Aggregation in single technology (FDD) does not provide extra utilization efficiency

• FDD uplink traffic is approx. 11%, in STC network.

- Carrier Aggregation: TDD & FDD Convergence——Using FDD Uplink for part of TDD uplink to increase the DL ration of TDD and increase the efficiency of FDD uplink

• TDD & FDD CA provides better utilization than FD only CA. FDD & TDD CA is the most efficient way of utilizing the available spectrum.

• With TDD & FDD Carrier Aggregation, the whole spectrum range can be better utilized to supplement coverage and capacity advantages.

- Carrier Aggregation: TDD & FDD Trial——STC and Nokia carried out a successful (first in the world) TDD & FDD CA demonstration, providing up to 260 Mbps downlink speed

- TDD & FDD convergence can take advantage of existing Spectrum which is critical to cater future data requirement.
