Claim 15:
16. A communication apparatus, comprising:
circuitry configured to:
acquire first information from a base station via wireless communication, wherein the first information is acquired based on a number, of terminals accommodated in a cell of the base station, that is equal to or greater than a terminal count; and
select, based on the acquired first information, one of orthogonal multiple access (OMA) communication or non-orthogonal multiple access (NOMA) communication for communication with the base station, wherein
the OMA communication is a third step of a 4-step RACH procedure in which the communication apparatus transmits data required for initialization to the base station,
the data is transmitted using resources granted in a second step of the 4-step RACH procedure, and
the NOMA communication is a first step of a 2-step RACH procedure in which the communication apparatus transmits each of a preamble and the data required for the initialization to the base station.
