摘要： A method and system applies MAC transmission opportunity (TXOP) protection for multiple mode operation in a WLAN system. In particular, MAC mechanisms are defined to support multiple mode CTS frames, and multiple mode CF-End frames sent by the AP, each in a format appropriate for the corresponding mode which also applies to a single mode as a trivial case. MAC mechanisms permit truncation of TXOP duration for releasing the unused portion of the TXOP when no further data for transmission is available. Release of unused protected TXOP is possible for both protected AP transmissions and STA transmissions.

摘要： A method and apparatus for securing the wireless transmission of an aggregated frame are disclosed. An aggregated frame is generated by aggregating at least one subframe and a security field. The security field is used to secure the entire aggregated frame. The contents of the security field may be generated from a group key or a pairwise key. For example, the security field may include an initialization vector (IV), an extended IV (EIV), a message integrity code (MIC) and an integrity check value (ICV). When a group key is used for a group of receivers, the group key may be changed as a new receiver enters into the group or an existing receiver leaves the group. Alternatively, the group key may be changed periodically. The subframes may be data frames, control frames, management frames, action frames or any type of frames.

摘要： A method for addressing groups of stations in a wireless communication system begins by assigning the stations in the system into a number of groups. A group identifier is signaled to each station and the group identifier is indicated in a frame for each group that has data in the frame. The addressing method can be applied to power savings for the station, wherein the station enters a power saving mode if the group identifier for the station is not present in the frame.

摘要： A wireless local area network (WLAN) includes at least one high throughput-enabled access point (AP) and at least one high throughput-enabled station (STA). A STA and a target AP communicate high throughput-related information and the STA performs a basic service set (BSS) transition to the target AP based on the high throughput-related information. The high throughput-related information may be included in an IEEE 802.11r, 802.11k, or 802.11v signaling message. The STA may send measurement reports for an extended range and a normal range of an AP separately, or may send a combined measurement report for an extended range and a normal range of an AP. A network management entity may obtain current status information of the STA and the AP regarding high throughput capabilities, features and parameters and selectively enable and disable at least one of the high throughput capabilities, features and parameters of the STA and the AP.

摘要： High throughput (HT) devices are required to support defragmentation for reassembling a medium access control (MAC) service data unit (MSDU) or a MAC protocol data unit (MPDU) from its fragments, but may or may not fragment data to be transmitted. In one embodiment, a wireless transmit/receive unit (WTRU) includes a data defragmentation unit which defragments any fragmented data received by the WTRU, but the WTRU does not transmit fragmented data. In another embodiment, a WTRU includes a processor, a data fragmentation unit, a transmitter and a fragmentation selection unit. The processor determines whether or not the transmitter should transmit fragmented data. When fragmentation is desired, the processor controls the fragmentation selection unit such that the data fragmentation unit fragments data provided by the processor for transmission by the transmitter.

摘要： A method and apparatus are provided for signaling collision avoidance behavior, and in particular deferral and/or backoff behavior, within a communication frame. Preferably, collision avoidance data is explicitly communicated and wireless transmit/receive units (WTRUs) are configured to use such data to generate instructions to control the WTRUs' deferral, backoff and/or other collision avoidance behavior. Instructions generated by the WTRU in this regard may take the form of simply adjusting one or more timing control values used to dictate deferral, backoff and/or other collision avoidance behavior.

摘要： In a wireless communication system comprising at least one access point (AP) and a plurality of stations (STAs), a method for transmission management of the wireless medium comprises the AP configuring a Multiple Receiver Aggregate Multi-Poll/Power Save Aggregation Descriptor (MMP/PSAD) frame with scheduled Uplink Transmission Time (ULT) information for the plurality of STAs. The AP then transmits the MMP/PSAD frame to the plurality of STAs. Upon successfully receiving and decoding the MMP/PSAD frame, STAs transmit during their scheduled ULT.

摘要： A method and system for reducing power consumption of a wireless transmit/receive unit (WTRU), (i.e., mobile station), are disclosed. A first WTRU measures a predetermined parameter and determines whether the measured predetermined parameter exceeds a threshold. If so, the first WTRU sends a sleep frame to a second WTRU. The sleep frame indicates sleep duration. The second WTRU receives the sleep frame and enters a sleep state for the sleep duration. The predetermined parameter may be an inactivity time of wireless medium. The second WTRU may or may not be allowed to send transmission to the first WTRU during the sleep duration. The sleep frame may be a control frame, a management frame, a data frame or an action frame. One of a multiple receiver aggregate (MRA) multi-poll frame, a power saving aggregation descriptor frame, or a power save multi-poll frame may be used as the sleep frame.
