The present disclosure relates to a transmission apparatus, a transmission method, a reception apparatus, and a reception method that can ensure a reduced processing burden on a receiving side in LPWA (Low Power Wide Area) communication.
Communication data is sent and received at a communication time of day and a communication frequency based on group identification information set for groups into which a plurality of transmission apparatuses is divided and communication interval information shared by the transmission apparatuses and a reception apparatus, rather than individual identification information. The present disclosure is applicable to an LPWA communication system.
