FIELD: physics; communication.
SUBSTANCE: invention relates to wireless communication for advanced block acknowledgement. In one version, a receiving device indicates delay in decoding for an aggregate frame of maximum size with coordination of block acknowledgement, which can be used by a transmitting device to determine which request for block acknowledgement the block acknowledgement is responding to. In another version, a transmission serial number (TSN) can be incorporated into the request for block acknowledgement. The receiving device incorporates a TSN into the corresponding response for acknowledgement. This enables the transmitting device to determine which frames are "in transmission". The TSN can be used to identify blocks. In another version, a TSN can be associated with one or more transmitted frames. Although the TSN is not transmitted with the request for block acknowledgement, the transmitting device can determine which TSN corresponds to the block acknowledgement contained in it. A combination of these methods can be developed. Other various aspects are also presented.
EFFECT: improved block acknowledgement.
