1. A method of wireless communication at a user equipment (UE), comprising:
receiving, from a network entity, an indication of at least two types of random access occasions (ROs) including a first RO type and a second RO type for communicating in a first coverage area of the network entity as part of a random access process for the UE to establish a connection with the network entity in the first coverage area;
determining to transmit a preamble using the one of the first RO type or the second RO type based on a type of the UE, wherein the type of the UE indicates:
whether the UE is capable of determining information regarding one or more of a round-trip delay or a frequency shift for communication between the UE and the BS prior to transmitting the preamble; or
whether the UE has information regarding a location of the UE and a location of the BS; or
whether the UE supports a satellite based positioning system; and
transmitting, to the network entity, a preamble on an RO of one of the first RO type or the second RO type based on the determining, wherein a preamble format of the preamble is based on whether the RO is of the first RO type or the second RO type.
