1. An information processing device, comprising:
processing circuitry configured to
perform control to receive an aggregated media access control protocol data unit (A-MPDU) subframe from another information processing device, the A-MPDU subframe having backward compatibility and including address fields;
upon detecting a frame check sequence (FCS) up to a media access control (MAC) header of the A-MPDU subframe, in a case where there is no error in data of the MAC header of the A-MPDU subframe, perform control to stop reception of an A-MPDU including the A-MPDU subframe based on first information of the address fields, which are included in the MAC header of the A-MPDU subframe; and
raise a carrier sense level for channel access in a case where second information of the address fields of the A-MPDU of which the reception is stopped is not for an information processing apparatus to which the information processing device is connected.
