Question

In LTE, what is the benefit of PAPR reduction in the uplink?

(a) Improved uplink coverage

(b) Lower UE power consumption

(c) Reduced equalizer complexity

(d) Improved uplink coverage, lower UE power consumption and reduced equalizer

I had been asked this question in semester exam.

The above asked question is from Long Term Evolution (LTE) topic in division 4G of Wireless/Mobile

Answer 1

The correct choice is (d) Improved uplink coverage, lower UE power consumption and reduced equalizer

Explanation: PAPR is the relation between the maximum power of a sample in a given OFDM transmit symbol divided by the average power of that OFDM symbol. PAPR reduction in the uplink leads to improved uplink coverage, lower UE power consumption and reduced equalizer complexity.
