    摘要: Methods and structures are disclosed for use in implementing downlink spatial division multiple access (SDMA) in a wireless network. In at least one embodiment, a number of orthogonal sets of user devices are first identified within a coverage area. One of the identified orthogonal sets may then be selected based on a predetermined selection criterion. An SDMA exchange may then be initiated for the selected orthogonal set.

    摘要: In Spatial Division Multiple Access (SDMA) communications, mobile devices that are transmitting to a base substantially simultaneously during a predetermined communications phase may wait until after an end of the predetermined communications phase to receive acknowledgments to their transmissions, so that a mobile device making a relatively short transmission does not experience an acknowledgement timeout while another mobile device is still completing a relatively long transmission. In some embodiments, the mobile devices may transmit a non-immediate block acknowledgement request during the communications phase.

    摘要: A frame format provides for wideband wireless local area network communications and informs narrower-band communication units when the channels are occupied by wider-band communication units. In some embodiments, the frame format includes a channelization field identifying channels that are used for communicating subsequent wideband fields of a packet, and a wideband-header field communicated on the identified channels. The wideband-header field may identify sub-fields that may be present in the wideband-header field, and may identify the presence of a wideband-data field. A long-compatibility field may be present that provides protection at the MAC level. The long-compatibility field may transport MAC frames that may include medium-reservation information compatible with narrower-band communication units.

    摘要: A wireless local area network (WLAN) device transmits a header over an air interface, at a first modulation rate. The header may include an indication of a second modulation rate that will be used to transmit a consolidated payload. The device further transmits the consolidated payload at the second modulation rate. The consolidated payload includes multiple data units. In one embodiment, the consolidated payload includes delimiters with validation fields associated with the various data units.

    摘要: Systems and methods for implementing a medium access group assignment of stations (STAs) are disclosed. An access point (AP) device may be configured to allocate a chosen beacon interval to a medium access group (MAG). Further, the AP device may assign STAs to different MAGs. After assignment to a particular MAG, the STAs that are associated to the particular MAG may use the configured beacon interval during transmission and reception of messages.
