The ACLR limits for NR devices and base station have been derived based on extensive analysis of NR coexistence with NR or other systems on adjacent carriers. For an NR BS, there are ACLR requirements both for an adjacent channel with an NR receiver of the same channel bandwidth and for an adjacent LTE receiver. The ACLR requirement for NR BS is set to 45 dB. This is considerably more stringent than the ACS requirement for the device, which implies that in the downlink, the device receiver performance will be the limiting factor for ACIR and ...
