A communication system, a method, and one or more non-transitory computer-readable storage devices allowing joint a user equipment to perform initial access with terrestrial and non-terrestrial communication nodes of a service area. The service area is partitioned into terrestrial initial-access zones and non-terrestrial initial-access zones with each terrestrial initial-access zone associated with one or more of the terrestrial communication nodes and each non-terrestrial initial-access zone associated with at least one of the non-terrestrial communication nodes. The user equipment uses positioning reference signals from positioning anchors to determine its location, determine a zone from the terrestrial and non-terrestrial initial-access zones based on the location, select one of the terrestrial and non-terrestrial communication nodes based on the determined zone, and establishing communication with the selected communication node.
