摘要： An apparatus and method is disclosed for announcing to a wireless station in a wireless network that a Quality of Service (QoS) service schedule is pending for the wireless station. The apparatus of the invention comprises a hybrid coordinator that is capable of creating and sending to the wireless station an announcement of a pending Quality of Service (QoS) service schedule. The wireless station delays entering a power save mode of operation until the wireless station receives the QoS service schedule or until a selected timeout period expires.

摘要： An apparatus and method is disclosed for providing a Quality of Service (QoS) service schedule and bandwidth allocation message to a wireless station in a wireless network. The apparatus of the invention comprises a hybrid coordinator that is capable of (1) creating a Quality of Service (QoS) service schedule and a bandwidth allocation message for a wireless station and (2) sending the QoS service schedule and the bandwidth allocation message to the wireless station. The wireless station is capable of using the scheduling information to perform power management by entering a power save mode during times when the hybrid coordinator has not scheduled any transmission opportunities.

摘要： A distributed MAC protocol is provided that includes a superframe (102) having a slotted Beaconing Period (104) and a data transfer period (103). The provided superframe (102) comprises a plurality of medium access slots (107) and a plurality of medium access slots (107) is assigned to the slotted Beaconing Period (104). The Beaconing Period length (106) may be fixed or variable.

摘要： A plurality of methods, computer program product, and apparatus that use a lower 32 bit field of a 64-bit 802.11 TSF timer, so as to encode the reference time instant without the ambiguity as to whether there the reference time is referring to a future time or a past time. According to an aspect of the present invention, the fact that the low order 32 bits of the TSF timer wraps over in about 71 minutes is exploited to remove any ambiguity in the reference times contained in the Schedule Element frame. One method employs an algorithm base on distance between two reference points to determine whether the timer has wrapped around a time period, and another method uses a delay interval or a timeout to determine whether or not the TSF timer is wrapped or unwrapped. Another method includes determining whether an absolute value of X−O is less than, or greater than or equal to maximum value M/2.

摘要： A wireless local area network (WLAN) includes at least one hybrid coordinator (HC) and at least one Quality of Service Station (QSTA). The HC transmits a schedule frame element (SEF). The WLAN also includes a clocking mechanism that sets a substantially absolute start time of a service interval. A method of synchronizing the HC and the QSTA includes transmitting a schedule element frame (SEF), and setting a substantially absolute start-time of a service interval, and a first transmitted frame element.
