摘要： A method performed by STA may comprise receiving, from a first AP, a first beacon frame comprising a first relay information element including a first field that indicates whether a root AP BSSID field is included in the first relay information element, determining that a first root AP BSSID field is included in the first relay information element and determining that the first AP is a relay AP of a root AP identified by the first root AP BSSID field. The method may further comprise receiving, from a second AP, a second beacon frame comprising a second relay information element including a second field that indicates whether a root AP BSSID is included in the second relay information element and determining that a root AP BSSID field is not included in the second information element and determining that the second AP is a root AP.

摘要： Mechanisms may be used for aggregating acknowledgement (ACK), block ACK (BA) and/or short packets transmissions for multi-user (MU) wireless communication systems. Aggregation mechanisms may be used for uplink (UL) and/or downlink (DL) orthogonal frequency division multiple access (OFDMA), and/or UL/DL multiple-user multiple input multiple output (MU-MIMO) transmissions, for example. Multi-user short packets may be aggregated and/or simultaneously transmitted for DL, UL, or peer-to-peer (P2P) transmissions.

摘要： Methods and apparatuses are described herein for prioritizing sidelink communication transmissions. In accordance with one example embodiment, an apparatus may transmit, to a network node, assistance parameters associated with sidelink communication comprising quality of service (QoS) parameters. The apparatus may receive, from the network node, configuration parameters associated with sidelink communication that comprise a logical channel configuration, a mapping of a QoS parameter to a sidelink radio bearer, and a mapping of the sidelink radio bearer to a sidelink logical channel. The apparatus may receive a sidelink resource grant and may select, based on the logical channel configuration, one or more sidelink logical channels to be served by the sidelink resource grant. The apparatus may transmit a generated a medium access control (MAC) protocol data unit (PDU), comprising data associated with the selected one or more sidelink logical channels, using the received sidelink resource grant.

摘要： A method performed by a STA may comprise receiving a frame, from a first AP including an indication of a configuration change counter (CCC) associated with a second AP. The CCC may be an unsigned integer that increments when an update to one or more AP parameters of the second AP has occurred. The method may further comprise establishing a first wireless link with the first AP and establishing a master key via at least the first wireless link.

摘要： A method for receiving a backoff value at a wireless station is presented. A traffic indication map is received at the station, wherein a backoff number is implicitly assigned to the station based on a position of the station within the traffic indication map. The backoff value is determined by multiplying the backoff number by a predetermined time value.

摘要： As part of carrier assignment and configuration for multicarrier wireless communications, a single uplink (UL) primary carrier may provide control information for multiple concurrent downlink (DL) carriers. Optionally, control information for each DL carrier may be transmitted over paired UL carriers. Carrier switching of UL and/or carriers, including primary and anchor carriers, may occur during normal operation or during handover, and may occur in only the UL or only the DL direction. A unidirectional handover is performed when only an UL carrier or only a DL carrier is switched as part of a handover. Switching of UL and/or DL carriers may be from one component carrier or a subset of carriers to another component carrier, another subset of carriers, or all carriers in the same direction.

摘要： Methods and apparatuses are related to multi-user parallel channel access (MU-PCA). For example, a wireless transmit/receive unit (WTRU) is provided that is one of the plurality of WTRUs operable to simultaneously communicate via a plurality of channels managed by an access point (AP). The WTRU includes a receiver configured to receive, from the AP, over at least one channel of the plurality of channels, a group poll (G-Poll) message that includes a resource allocation that indicates at least one allocated channel of the plurality of channels for the WTRU; and a transmitter configured to transmit an uplink request message, to the AP in response to the G-Poll message, over the at least one allocated channel of the plurality of channels, the uplink request message corresponding to uplink data the WTRU has for transmission to the AP.
