    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 application describes a method to merge two wireless networks in which each terminal gets a beacon slot within the beacon period. In order to merge two networks, the beacon slots have to be time-coordinated such that the beacon slots of the first network are completed before the beacon slots of the second network begin. The method includes transmitting a beacon frame having a beacon period switch information element which instructs the neighboring terminals in the first network of the need to merge, provides clock synchronization information; provides the time of the merge; and informs the neighboring terminals which beacon slot to occupy in the beacon period of the merged network. In order to deal with hidden terminals, the information needs to be forwarded terminal-to-terminal within each network.

    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.
