Abstract:
1. A method, comprising: prior to wireless transmission of a data signal by an electronic device to a network element in a wireless communication system, the electronic device receiving signalling information from the network element relating to parameters for the wireless transmission of the data signal, the electronic device deducing maximum peak-to-average ratio control information from the signalling information for adjusting properties of a power amplifier of the electronic device affecting power efficiency of the power amplifier in amplifying the data signal for the wireless transmission to the network element, the electronic device adjusting the properties of the power amplifier including a load impedance of the power amplifier and at least two parameters of the power amplifier according to the deduced maximum peak-to-average information and mappings between the deduced maximum peak-to-average information and values of the at least two parameters of the power amplifier and the load impedance stored in a memory or control logic of the electronic device so that the power efficiency of the power amplifier is tuned by the adjusting of the load impedance and the values of the at least two parameters, wherein the at least two parameters of the power amplifier include a bias current for the power amplifier, and after the tuning of the power efficiency of the power amplifier, the tuned power amplifier amplifying the data signal and the electronic device transmitting the amplified data signal in the wireless transmission to the network element in the wireless communication system.
