1. A method for reducing self-desense in a downlink band due to two or more uplink bands of an uplink transmission, the method comprising:
selecting two or more uplink bands;
selecting a downlink band for a device using the two or more uplink bands;
determining, by computation or retrieval or direct measurement, intermodulation distortion values for available uplink band combinations and available downlink bands;
using the intermodulation distortion values to determine if there is intermodulation distortion for the downlink band given the two or more uplink bands;
in response to determining presence of intermodulation distortion for the downlink band, comparing an average power of the two or more uplink bands to a power threshold, and when the average power exceeds the power threshold, performing one of:
(a) allocating the uplink transmission to a clean band determined to be free of said intermodulation distortion; or
(b) when a clean band is unavailable for allocation, determining a link margin for each of the two or more uplink bands to identify the uplink band having the greatest link margin, and subsequently increasing a modulation order of the identified uplink band.
