    摘要: A peer-to-peer communication system using a direct link setup (DLS) is disclosed. A mobile station (STA) establishes a direct communication link with another STA by sending a message requesting a DLS to an access point (AP), (i.e., a centralized controller). The AP may accept or reject the DLS request based on channel measurements. If the DLS request is accepted, the DLS is established such that the STAs may directly communicate with each other. An established DLS connection may be torn down by the AP sending a message including a DLS teardown request to one of the STAs, or based on channel measurements. The system may be an Ad hoc network comprising a plurality of STAs without an AP where each STA maintains a database of one-hop and two-hop STAs, and establishes a direct link to other STAs after informing neighboring STAs of an intention to establish a direct communication link.

    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: A method and apparatus for protecting high throughput (HT) stations (STAs) are disclosed. In one embodiment, a physical layer (PHY) legacy preamble transmitted by one STA is decoded by another STA that does not use a legacy preamble. In another embodiment, one STA is identified by another STA by using bits in the preamble of a packet to indicate which PHY type will be used in the remaining portion of the packet. In yet another embodiment, one STA sends ready-to-send (RTS)/clear-to-send (CTS) or CTS-to-self messages for reserving a medium in the presence of another STA of a different type than the one STA. In yet another embodiment, an access point (AP) transmits a beacon or an association message including a capability information element (IE) that indicates operation or support for a legacy preamble, HT STA preambles and a medium access control (MAC) packet transmission with HT protection mechanisms.

    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 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.
