Abstract
A wireless device and method of power consumption reduction are generally described herein. The wireless device may map a plurality of data symbols to sub-carriers for an orthogonal frequency division multiplexing (OFDM) transmission. The wireless device may divide the plurality of data symbols into first and second groups of data symbols. The wireless device may generate a first OFDM signal from the first group of data symbols for amplification by a first power amplifier (PA). The wireless device may generate a second OFDM signal from the second group of data symbols for amplification by a second PA. The data symbols of the first and second groups may be selected to provide a PAPR of the first OFDM signal that is lower than a PAPR of a composite OFDM signal based on the plurality of data symbols.
