Claim 6:
7. A method of wireless communication performed by a base station of a mobile network, comprising:
transmitting 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, wherein the first system information comprises a first portion of a plurality of synchronization signal blocks (SSBs), the first portion of the plurality of SSBs being configured for the aerial cell or for the at least one aerial sector, wherein transmitting the system information comprises:
transmitting, via a first uptilt beam of the one or more uptilt beams, an aerial SSB of the first portion of the plurality of SSBs, the aerial SSB indicating a channel state information-reference signal (CSI-RS) configuration for the aerial cell or for the at least one aerial sector; and
transmitting, via a second uptilt beam of the one or more uptilt beams and according to the CSI-RS configuration, a CSI-RS, the first uptilt beam having a wider shape than the second uptilt beam;

performing, according to the 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.
