Abstract: Methods, apparatuses, computer readable media for uplink transmission power control in a wireless network. An apparatus of a wireless device comprising processing circuitry is disclosed. The processing circuitry is configured to decode a trigger frame from an access point for an uplink communication, the trigger frame comprising an uplink resource allocation for the station, the uplink resource allocation including common information and per station information, the common information including an indication of a maximum receive power at the access point, the per station information comprising an identification of the station, and an indication of a resource unit (RU). The processing circuitry may be further configured to: encode an uplink (UL) physical layer convergence procedure (PLCP) protocol data unit (PPDU)(UL-PPDU) in accordance with the indication of the RU. The processing circuitry may be further configured to: determine a transmit power for the UL-PPDU based on the maximum receive power.

Abstract: An envelope tracking arrangement is disclosed and includes a level select component, a chunk supply component and a power amplifier. The level select component is configured to segment an input signal into chunks based on time and to select a chunk level for each chunk based on information or envelope information. The chunk supply component is configured to selectively provide a discrete supply voltage according to the selected chunk level. The power amplifier is configured to generate a radio frequency (RF) output signal based on the input signal and utilizing the discrete supply voltage.

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.

Abstract: Embodiments of a radio-circuit apparatus are generally described herein. The radio-circuit apparatus may comprise circuitry to generate an output baseband signal to reduce one or more localized peak power levels of an input baseband signal. The output signal may be based on a difference between an input baseband signal and an excess signal. The radio-circuit apparatus may further comprise a hard clipper circuit to restrict power levels of the input baseband signal to a clip range to generate a clipped signal. The radio-circuit apparatus may further comprise one or more filters to filter a predicted OOB emission signal in accordance with a target OOB emission spectrum. The predicted OOB emission signal may be based on a difference between the input baseband signal and the clipped signal.
