Claim 0:
1. A method of wireless communication performed by a base station of a mobile network, comprising:
transmitting first system information corresponding to an aerial cell of the mobile network or a cell having at least one aerial sector, the aerial cell or the at least one aerial sector being formed by one or more uptilt beams of the base station;
transmitting second system information corresponding to a terrestrial cell of the mobile network, the terrestrial cell being formed by one or more downtilt beams of the base station, the second system information being separate from the first system information, wherein transmitting the second system information comprises transmitting a plurality of terrestrial synchronization signal blocks (SSBs), the plurality of terrestrial SSBs being configured for the terrestrial cell of the mobile network, wherein transmitting the second system information comprises:
transmitting a terrestrial SSB of the plurality of terrestrial SSBs; and
transmitting a channel state information-reference signal (CSI-RS) according to a CSI-RS configuration, the CSI-RS configuration being based at least on the terrestrial SSB;

performing, according to the first system information, a random access channel (RACH) procedure with an aerial user equipment (UE); and
establishing, via the aerial cell or the at least one aerial sector, a communications link with the aerial UE.
