摘要： A method and system for enhancing the capabilities of wireless local area network (WLAN) control frames in general, and particularly block acknowledgement (ACK) frames, such as block ACK request (BAR) frames and block ACK response (BA) frames are disclosed. Furthermore, the functionalities these frames provide are extended by indicating the types of such functionalities within the BAR or BA frame formats. This enables the BAR or BA frames to be used more flexibly and on an as-needed basis, without the restriction of simultaneously providing all functionalities. The BAR/BA setup and negotiation procedure is also modified to provide more flexibility. In another embodiment, request to send (RTS) frames or clear to send (CTS) frames are used for the purpose of granting reverse direction traffic, and may be aggregated with data 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 method and system for eliminating interference caused by hidden nodes is disclosed. An initiator control message is defined for an initiator, (typically a wireless station (STA)), in order to begin an aggregate frame exchange with at least one responder. The initiator control message includes information on the queue sizes at the initiator. A responder, (typically an access point (AP)), sets up the required protection for the transmission of data by the initiator based on information on the queue sizes indicated in a field of the initiator control message using a responder control message. Other STAs that receive the responder control message set parameters for a wireless medium access accordingly. In another embodiment, multiple receiver aggregate multi-poll (MMP) and power save aggregation descriptor (PSAD) control frames are configured for transmission by a non-AP STA to provide enhanced scheduling and mitigate hidden node problems.

摘要： A method and system for improving responsiveness in exchanging management and control frames in a wireless local area network are disclosed. An initiator sends a frame (action, management, control or data frame) to a responder. Upon correctly receiving the frame, the responder sends a response frame to the initiator instead of directly sending an acknowledgement (ACK) packet. The responder preferably accesses the wireless medium to send the response frame in a short inter-frame spacing (SIFS). With this scheme, a long delay associated with having to contend for the wireless medium to send the response frame is avoided and therefore, the responsiveness and timeliness of the feedback mechanism is significantly enhanced. The response frame may be piggybacked on or aggregated with another packet.
摘要翻译：公开了一种在无线局域网中提高交换管理和控制帧响应性的方法和系统。发起者向响应者发送帧（动作，管理，控制或数据帧）。在正确接收到帧时，响应者向发起者发送响应帧，而不是直接发送确认（ACK）分组。响应者优选地访问无线介质以以短的帧间间隔（SIFS）发送响应帧。利用这种方案，避免了与必须争取无线介质发送响应帧相关联的长延迟，因此反馈机制的响应性和及时性得到显着增强。响应帧可以搭载在另一个分组上或与另一分组聚合。

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： A method and apparatus for controlling access to Aloha slots are disclosed. An access point (AP) assigns at least one Aloha slot for a wireless transmit/receive unit (WTRU). The AP may assign the Aloha slot based on quality of service (QoS) policy, measurements of a predetermined metric, or combination of both. The metric may be the number of WTRUs assigned to each Aloha slot or a traffic load on each Aloha slot. The AP may also assign an Aloha slot over multiple superframes. The AP may restrict allowed access categories (ACs) in the Aloha slots. Alternatively, the AP may partition the Aloha slots into a plurality of groups and indicate an AC allowed in each group of Aloha slots. The AP may indicate an access period or frequency for each AC.

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.
摘要翻译：公开了一种用于降低无线发射/接收单元（WTRU）（即移动站）的功率消耗的方法和系统。第一WTRU测量预定参数并确定所测量的预定参数是否超过阈值。如果是，则第一WTRU向第二WTRU发送睡眠帧。睡眠帧指示睡眠持续时间。第二WTRU接收睡眠帧并进入休眠状态以进行睡眠持续时间。该预定参数可以是无线介质的不活动时间。在睡眠持续时间期间，第二WTRU可以或可以不被允许向第一WTRU发送传输。睡眠帧可以是控制帧，管理帧，数据帧或动作帧。可以使用多个接收机聚合（MRA）多轮询帧，功率节省聚合描述符帧或省电多轮询帧中的一个作为睡眠帧。

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.
