1. A communication device that performs wireless communication using a plurality of links, the communication device comprising:
a transceiver; and
control circuitry that:
receives packets on individual links of the plurality of links from a plurality of senders,
stores information about an acquisition success/failure of the packets received on the individual links of the plurality of links in individual storages that are link specific,
determines whether or not a block acknowledgement policy has been set for a specific sender of the plurality of senders, and
upon determining that the block acknowledgement policy for the specific sender has been set:
determines whether or not any of the packets received on the individual links of the plurality of links are from the specific sender, and
only for the packets received on the individual links of the plurality of links that are from the specific sender:
retrieves corresponding acquisition success/failure information from the individual storages,
stores the corresponding acquisition success/failure information in a common storage of a cache type,
upon determining that receipt of the packets from the specific sender on the individual links of the plurality of links has ended, generates a block acknowledgement signal that includes the information about the success/failure of the acquisition of the block of packets from the specific sender, and
transmits the block acknowledgement signal on one of the individual links of the plurality of links.
