MC Max AT Power Backoff
indicates the power backoff to use when multiple carriers are transmitted.
The
AT Max Power
defines the upper limit for the
Expected Power
if there is only one carrier transmitted, whereas the
MC Max AT Power Backoff
is an indicative of power attenuation and used to adjust the expected power introduced by more than one carrier transmitting. In this case the value of multicarrier AT max power backoff will be subtracted with another value from the
AT Max Power
specified by the user to indicate the upper limit of the Expected Power, see
Range of Expected power
.
