Apparatus and methods for modulation partition and transmission via multiple antennas for enhanced transmit power capability are provided herein. In certain embodiments, an RF communication system includes a transceiver that generates a first RF signal and a second RF signal corresponding to partitions of a modulated RF signal. For example, the first RF signal and the second RF signal can be associated with different RB allocations of one or more channels of a frequency band. The RF communication system further includes a first transmit chain that processes the first RF signal to generate a first RF output signal for transmission on a first antenna, and a second transmit chain that processes the second RF signal to generate a second RF output signal for transmission on a second antenna.
