    Abstract: PROBLEM TO BE SOLVED: To provide a circuit, method and apparatus for decreasing overhead and channel band required for a block request and acknowledgement.SOLUTION: An extension block acknowledgement acknowledging a frame received for different data streams is used. Another system sends out an acknowledgement after generation of a trigger event. In the other systems, an acknowledgement field is included in a transmission data frame thereby eliminating the necessity of an acknowledgement frame. These block acknowledgement and acknowledgement field may also include an acknowledgement of a frame received for each of data streams having different traffic identifiers, and the acknowledgement may also be provided for all the received frames, for any specific traffic class or a group of classes, or for a specific user priority.

    Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate calibration techniques for distortion introduced by in-phase/quadrature (I/Q) imbalance and mixing-product modulated images.SOLUTION: An in-phase (I) signal and a quadrature (Q) signal are generated in a transmitter 200, fed to IF mixers 208, 209, and summed by a summer 210. The summed IF signal is fed to a mixer 214, and the resultant RF signal is then transmitted by an antenna 216. To allow RF-based calibration to compensate for contributions of mixing-product modulated images, an RF feedback signal 218 is examined, and adjustments (e.g., to gain and/or phase of I and/or Q signal paths) is made so as to compensate for unwanted signal components.

    Abstract: PROBLEM TO BE SOLVED: To provide a circuit, a method, and an apparatus that provide high-throughput control fields that reduces overhead by using TXOP handoffs in wireless networks.SOLUTION: 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 station may do with any remaining TXOP which it received, or what types of data may be transmitted by the receiving station may be set. These various conditions may be combined or omitted in any logic combination.
