Efficient wireless transmission opportunity handoff |
(57) Circuits, methods, and apparatus that provide high-throughput control fields that,
among other functions, provide efficient TXOP handoffs in wireless networks. A handoff
may be made by setting one or more bits in a field in a QoS frame, such as the HT
control or other appropriate field.. Various conditions may be placed on a handoff
by a granting station. For example, conditions specifying where a station receiving
a TXOP handoff may send data, what the receiving station may do with any remaining
TXOP, or what types of data may be transmitted by the receiving station may be imposed.
These various conditions may be combined or omitted in any logic combination.
