Explain the difference between TDD and FDD in 5G !a.In FDD mode, both uplink and downlink use the same spectrum frequencies but at different timesb.In TDD mode, both uplink and downlink can transmit at the same time at different spectrum frequenciesc.In FDD mode, both uplink and downlink can transmit at the same time at different spectrum frequencies

The difference between TDD (Time Division Duplex) and FDD (Frequency Division Duplex) in 5G lies in how they use spectrum frequencies for uplink and downlink transmissions.

a. In FDD mode, both uplink and downlink use different spectrum frequencies but at the same time. This means that data can be sent (uplink) and received (downlink) simultaneously without interference because they are on separate frequency bands.

b. In TDD mode, both uplink and downlink use the same spectrum frequencies but at different times. This means that data transmission (either uplink or downlink) takes place in turns, using the same frequency band. This can be more efficient in terms of spectrum usage, but it requires precise timing to avoid interference.

c. The statement is incorrect. In FDD mode, both uplink and downlink can transmit at the same time but at different spectrum frequencies, not the same.
