Abstract
This disclosure relates to an apparatus, system, and method for generating uplink transmissions using a polar architecture including a phase locked loop with potential for two point injection. According to some embodiments, frequency resources allocated for a transmission may be determined. A cartesian baseband signal may be generated for the uplink transmission. The cartesian baseband signal may be converted to a polar baseband signal, including a baseband phase signal and an amplitude signal. Modulation parameters, potentially including whether to use one point injection or two point injection with a phase locked loop, may be determined. The baseband phase signal may be upconverted to an RF phase signal according to the determined modulation parameters. The RF phase signal may be amplified according to the amplitude signal to produce an RF signal. The RF signal may be transmitted.
