TABLE 3.7 Assumed UE ACLRs for corrected UE PR values Channel offset N (8 MHz channels) Centre frequency offset (MHz) ACLR (dB) 1 10 25.2 2 18 32.2 Other offsets (corresponding to –65 dBm/8 MHz) 26-74 88.0 The ACLR correction method is described in Recommendation ITU-R BT.2033. The co-channel PR0 values used in the correction calculation were the AWGN figures in Table 3.8. It should be noted that, for a frequency offset ∆f, the adjacent channel selectivity (ACS) of the receiver should be calculated from the un-corrected protection ratio at the offset (PR(∆f)). Different values than those appearing in Table 3.7, will require a recalculation of the corrected UE PR values.
