Abstract: The present invention relates to an optical recording apparatus capable of recording information on an optical record carrier. Radial tracking control is performed by the 3 spot differential push pull (PP) method. The optical recording apparatus has means for obtaining a first and second difference signal from detection signals of a reflection of a main light beam (C) and a first and a second sub light beam (A,B), and means for subtracting the second difference signal from the first difference signal so as to obtain a tracking error signal (TES). The second difference signal is adjusted by a gain factor (g) so as to compensate for a difference in intensity between the reflected light of the first and the second sub light beams during information writing. In particular, a solution may compensate for the difference in the reflections for the first and second sub light beam (A,B) so that a possible radial offset is avoided.

Abstract: A method and apparatus for alleviating congestion of a wireless medium used by an access point (AP) and a plurality of wireless transmit/receive units (WTRUs) is disclosed. If congestion is determined to exist on the wireless medium, a determination is then made as to whether there are any low priority traffic streams established between the AP and at least one of the WTRUs. If there are no low priority traffic streams established between the AP and at least one of the WTRUs, selected ones of the associated WTRUs are disassociated with the AP based on the amount of time spent by the WTRUs trying to transmit and retransmit unacknowledged packets or on a specific traffic stream access category. If low priority traffic streams have been established, the packet transmission delay associated with the low priority traffic streams is increased when congestion exists. Otherwise, the packet transmission delay is decreased.
