A communication apparatus that performs cooperative transmission according to Joint Tx is provided.
A communication apparatus configured to operate as an AP that transmits packets to a subordinate STA and an STA connected to another AP includes a storage unit including a transmission buffer that stores packets for each STA, and a control unit that controls processing for sharing information on a sequence number of a transmission buffer for each STA between the APs. The control unit collects the information on the sequence number of the transmission buffer of each STA of each AP, and controls processing for transmitting packets to each STA on the basis of a difference in information related to the sequence number of the transmission buffer of each STA between the APs.
