    摘要: Wireless stations (108-1-108-N) contending for exclusive access for a predetermined period of time (S232) to transmit on a communication medium (112) are regulated by a common external controller (104) using a single timing parameter (S204). Attempts at transmission access are preceded by respective delays that are expired simultaneously and at a common rate by the stations at times when the stations sense the medium to be idle (S224). The delays are pseudo-randomly selected to avoid collisions among stations in their respective access attempts (S208). Default, initial values of the respective delays (S204) applied to the stations, when multiplied by the respective expected number of transmission attempts by the stations over the long term over periods of time when no transmission attempt is unsuccessful, yield respective products equal to a constant value common to all stations (S312). The default values therefore serve as a knob by which the controller regulates air time opportunity.

    摘要: The Station Management Entity (SME) 202 and/or Media Access Control (MAC) SubLayer Management Entity (MLME) 201 within a Hybrid Controller (HC) or wireless station (WSTA) 106, 109 for an IEEE 802.11 wireless data communications system 100 employ primitives in connection with a Schedule Quality of Service (QoS) Action frame. The primitives include: a request primitive formulated by the HC's SME 202 using the WSTA 106, 109 address and the Schedule Element from the Schedule QoS Action frame for transmission to the HC's MLME 201; a confirm primitive formulated by the HC's MLME 201 using a result code for transmission to the HC's SME 202; and an indication primitive formulated by the WSTA's MLME 201 using the Schedule Element for transmission to the WSTA's SME 202.

    摘要: A method of transmitting data frames over a data network comprises a step of sending said data frames from a transmitter to a receiver with an Inter Frame Space (IFS) time, which does not include a time (T2) that the transmitter needs to change from a receiver state to a transmitter state, thus substantially increasing the transmission efficiency.

    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.
