Device, system and method of communicating aggregate data units

摘要

Some demonstrative embodiments include devices, systems and/or methods of communicating aggregate data units. For example, a device may include a wireless communication unit to communicate an aggregate data unit including a plurality of data units in an increasing order of sequence numbers assigned to the data units, such that a first data unit having a first sequence number always precedes a second data unit having a second sequence number, greater than the first sequence number.

主权项

1. A wireless apparatus including one or more processors having circuitry, the circuitry to cause a station to:
at a start of a Transmit Opportunity (TxOP) or a Service Period (SP), transmit an aggregate data unit having only a normal acknowledge (ACK) policy, if at least one frame in a last Physical Layer Protocol Data Unit (PPDU) did not require an immediate response, the aggregate data unit including a plurality of data units in an increasing order of sequence numbers of said data units; receive a block acknowledgement; and in response to said block acknowledgement, retransmit unacknowledged data units in an increasing order of sequence numbers of said unacknowledged data units.
