1. A transmission device comprising:
a processor that generates a frame in a predetermined frame format; and
a transmitter that transmits the frame generated by the processor to a reception device, wherein
a receiver included in the reception device operates in one of a first mode and a second mode, and
the predetermined frame format:
includes a first field indicating whether information related to a wake-up process executed by the reception device that received the frame in the predetermined frame format is valid or not; and
when the first field indicates that the information is valid, further includes a second field indicating identification information identifying the reception device and a third field related to waking up a predetermined function while the reception device is operating in the second mode, the predetermined function being executed by the reception device as a function process that is based on the frame received by the receiver included in the reception device while operating in the second mode, the first mode is a mode in which the receiver included in the reception device is in standby for reception of the reception frame including at least the first field,
the second mode is a mode in which the receiver included in the reception device performs normal data frame transmission and reception,
the wake-up process transitions the receiver included in the reception device from the first mode to the second mode, and
after the wake-up process transitions the receiver included in the reception device from the first mode to the second mode, the reception device executes the function process related to the predetermined function based on the frame received by receiver included in the reception device while operating in the second mode.
