6.6.2.2 Adjacent Channel Leakage power Ratio (ACLR)

In the case a single carrier is assigned on the uplink, Adjacent Channel Leakage power Ratio (ACLR) is the ratio of the RRC filtered mean power centered on the assigned channel frequency to the RRC filtered mean power centered on an adjacent channel frequency.

In the case multiple adjacent carriers are assigned on the uplink, ACLR is the ratio of the sum of the RRC filtered mean power centered on each assigned channel frequencies to the RRC filtered mean powers centered on an adjacent channel frequency.
