1. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to:
determine a channel bandwidth (CBW); and
based upon the determined CBW, determine a maximum power reduction (MPR) for the CBW in accordance with an allowed MPR as defined by an equation,
wherein the equation is:

OG Complex Work Unit Math
in an instance in which the determined CBW is in a group of less than 50 MHz CBWs;
wherein the equation is:

OG Complex Work Unit Math
in an instance in which the determined CBW is in a group of equal to or larger than 50 MHz CBWs; and
where CEIL(x,0.5 dB) means rounding x upwards to a closest multiple of 0.5 dB.
