1. A base station, comprising:
control circuitry, which, in operation,
generates information on a terminal group among a plurality of terminals, the terminal group being a target of transmission by non-orthogonal multiplexing, and
generates a non-orthogonal multiplex access (NOMA) signal, wherein a length of the NOMA signal is determined based on a terminal with a lowest reception processing capability among the plurality of the terminals; and
transmission circuitry, which, in operation, transmits the information on the terminal group during a period for transmitting common information for the plurality of terminals, wherein:
the period for transmitting the common information for the plurality of terminals is during a period for transmitting control information addressed to the plurality of terminals, and
the information on the terminal group is associated with some frequency resource candidate values among a plurality of frequency resource candidates in allocation information of a frequency resource indicated in the common information.
