1. A multi-band transmitter device comprising:
control circuitry which, using a single frequency band, establishes a multi-band Block Ack agreement for a single Traffic Identifier (TID) between a transmitter's unified MAC address of the multi-band transmitter device and a recipient's unified MAC address of a multi-band recipient device, the multi-band Block Ack agreement being identified by the single TID, the recipient's unified MAC address, and the transmitter's unified MAC address;
a transmitter which, in operation, transmits to the multi-band recipient device, over a plurality of frequency bands, a plurality of MAC layer Protocol Data Units (MPDUs) belonging to the single TID;
wherein the transmitter, in operation, transmits a multi-band Block Ack request frame including a Multi-Band field that indicates a request for a Block Ack for multiple bands; and
a receiver which, based on the multi-band Block Ack agreement, receives on a first frequency band a multi-band block ack frame indicating reception statuses of the plurality of MPDUs transmitted over the plurality of frequency bands,
wherein the receiver, in operation, additionally receives a per-band block ack frame indicating a reception status of a subset of the plurality of MPDUs, the subset being transmitted on one frequency band among the plurality of frequency bands, and
wherein the per-band block ack frame is generated by the multi-band recipient device with partial state operation on each of the plurality of frequency bands.
