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 perform:
determining that a first non-terrestrial apparatus coverage area provided with a non-terrestrial apparatus will at least partially overlap with a first access coverage area provided with a terrestrial access network node at least one of at or during a first future time;
determining a first Doppler shift correction value, the first Doppler shift correction value corresponding to a frequency shift resulting from a relative velocity difference between the non-terrestrial apparatus and the terrestrial access network node at least one of at or during the first future time;
determining at least one first shifted non-terrestrial apparatus frequency with correcting at least one of at least one transmission or reception frequency of the non-terrestrial apparatus using the first Doppler shift correction value;
determining that a second non-terrestrial apparatus coverage area provided with the non-terrestrial apparatus will at least partially overlap with a second access coverage area provided with the terrestrial access network node at least one of at or during a second time;
determining a second Doppler shift correction value, the second Doppler shift correction value corresponding to a frequency shift resulting from a relative velocity difference between the non-terrestrial apparatus and the terrestrial access network node at least one of at or during the second time
determining at least one second shifted non-terrestrial apparatus frequency with correcting at least one of at least one transmission or reception frequency of the non-terrestrial apparatus using the second Doppler shift correction value;
based on the determined overlaps and the first and second Doppler shift correction values, performing a physical resource block blanking to prevent transmission or reception on impacted physical resource blocks from being scheduled by blanking physical resources corresponding to the frequencies that fall within a range of frequencies of the first and second shifted non-terrestrial apparatus frequencies, and
unblanking for use any previously blanked physical resource after the second time, and when there are no previously blanked resources, using resources corresponding to frequencies that fall within a range of frequencies of the first and second shifted non-terrestrial apparatus frequencies.
