Claim:
1. An apparatus of a wireless communication device configured for Tx-Tx transmission concurrency (TTC), the apparatus comprising: a first input configured to accept a first radio frequency (RF) signal; a second input configured to accept a second RF signal; a validity check circuitry configured to check a transmission power for the first RF signal against a first threshold transmission power; a standalone power amplifier having a standalone power amplifier input, a predistortion circuitry, and a standalone power amplifier output capable of being coupled to an antenna output; a shared power amplifier comprising a shared power amplifier input coupled to the second input and a shared power amplifier output capable of being coupled to the antenna output; a switching network controlled by the validity check circuitry and configured to couple the first input to the standalone power amplifier input when the transmission power for the first RF signal is above the first threshold transmission power and to couple the first input to the shared power amplifier input when the transmission power for the first RF signal is less than or equal to the first threshold transmission power; and a contention identification circuitry configured to identify a transmission conflict for an antenna coupled to the antenna output, wherein the contention identification circuitry is further configured to identify a conflict rate for use of the antenna by the first RF signal and the second RF signal.
