    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 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: 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 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 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.
