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 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： The method involves sending a request frame to a responder by an initiator, and sending a response frame to the initiator without sending a separate acknowledgement (ACK) frame for acknowledging receipt of the request frame. The response frame is sent by the responder within a short inter-frame spacing (SIFS) from time that the responder receives the request frame, where the responder has a request identity number in the response frame. An independent claim is also included for a wireless communication system comprising an initiator.
摘要翻译：该方法包括由发起者向请求者发送请求帧，并且向发起者发送响应帧，而不发送用于确认接收请求帧的单独的确认（ACK）帧。应答器在响应者接收到请求帧的时间内在短帧间距（SIFS）内由响应者发送响应帧，响应者在响应帧中具有请求标识号。还包括用于包括发起者的无线通信系统的独立权利要求。

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 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.
摘要翻译：一种方法和系统在WLAN系统中对多模式操作应用MAC传输机会（TXOP）保护。特别地，MAC机制被定义为支持多模式CTS帧，以及由AP发送的多模式CF-结束帧，每个帧的格式适合于对应的模式，其也适用于单个模式作为平凡的情况。当没有进一步的传输数据可用时，MAC机制允许截断TXOP持续时间以释放TXOP的未使用部分。对于受保护的AP传输和STA传输都可以释放未使用的受保护的TXOP。

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接收睡眠帧并进入睡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。第二WTRU可以或可以不允许在睡眠持续时间期间向第一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： 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.
