Abstract: Techniques are disclosed for determining customized frequency rotation values for a number of wireless channel configurations. The channel configurations may define various parameters of a wireless channel in accordance with a communication protocol, such as the channel bandwidth, the number of sub-channels, and which of the sub-channels may be punctured. The frequency rotation values may be obtained by determining the Peak to Average Power Ratio (PAPR) values for different combinations of frequency rotation values that are applied to the sub-channels of the wireless channel on a per-configuration basis. Thus, for each configuration, the lowest maximum PAPR or other suitable threshold value may be used to identify the frequency rotation values for that particular configuration. The frequency rotation values may then be applied at run time based upon the current wireless channel configuration for data transmissions via the wireless channel.

Abstract: A wireless device includes a controller configured to identify a scheduled transmission including a first section having a first bandwidth and a second section having a second bandwidth, select a transmit power limit for the scheduled transmission based on a relative duration of the first section compared to the second section, and select a transmit power value based on the transmit power limit, and a transmitter configured to perform the scheduled transmission with a transmit power indicated by the transmit power value.

Abstract: The present disclosure relates to a transmitter for transmitting a transmit signal comprising a first signal portion and a second signal portion. The transmitter comprises a power amplifier configured to amplify the transmit signal. The power amplifier is prone to undesired gain variations during the first and the second signal portion. The transmitter further comprises a transmit feedback receiver coupled to an output of the power amplifier and configured to feed back the transmit signal to generate a fed back first signal portion and a fed back second signal portion. Processing circuitry is configured to determine a first gain relation between the fed back first signal portion and the first signal portion and to determine at least one second gain relation between the fed back second signal portion and the second signal portion. Power adjustment circuitry is configured to adjust a transmit power of the transmit signal according to a variation between the first gain relation and the second gain relation.
