摘要： In the present invention, the subscriber unit (200) obtains a set of access point identifiers and measurement opportunity information for each access point identifier. A first measurement is performed on a first access point identified from the set of access point identifiers. A current timer value is determined after completing the step of performing, and a second access point identified from the set of access point identifiers in which to perform a second measurement is selected. Selecting the second access point is based on at least the measurement opportunity information for the second access point in relation to the current timer value.

摘要： The invention provides an enhanced passive scanning method for a wireless local area network, including the steps of transmitting at least one of a beacon signal or a gratuitous probe response in a WLAN channel by an access point. The gratuitous probe response is a supplemental beacon signal that is transmitted at intervals between the occurrence of regular beacon signals, but contains only essential information to allow mobile station manage roaming and timing.

摘要： A mobile station (106) establishes a real time communication link via an access point (102) for carrying voice or other time-sensitive data. A WLAN subsystem (204) of the mobile station is normally kept in a low power state. Upon initiating a communication link the mobile station signals to the access point that uplink poll-based power save delivery mode will be used (614), and the access point reserves resources to assure the necessary quality of service. The mobile station initiates a frame transaction by first powering up the WLAN subsystem (712), acquiring the WLAN channel (407), and transmitting a polling frame. Upon successful receipt of the polling frame the access point prepares to reply with a response frame at an unspecified time within service window, during which time the mobile station maintains the WLAN subsystem power up and ready to receive the response frame. Upon successful receipt of the response frame, the mobile station places the WLAN subsystem back into a low power state.

摘要： A mobile station (106) establishes a real time communication link via an access point (102) for carrying voice or other time-sensitive data. A WLAN subsystem (204) of the mobile station is normally kept in a low power state. Upon initiating a communication link the mobile station signals to the access point that unscheduled power save delivery mode will be used (614), and the access point reserves resources to assure the necessary quality of service. The mobile station initiates a frame transaction by first powering up the WLAN subsystem (712), acquiring the WLAN channel (407), and transmitting a polling frame. Upon successful receipt of the polling frame the access point prepares to reply with an aggregate response. The aggregate response commences by transmitting all data in an aggregate buffer, including both reserved and unreserved data buffers. Upon successful receipt of the aggregate response, the mobile station places the WLAN subsystem back into a low power state.

摘要： A mobile station establishes a schedule by which data is exchanged with an access point. The schedule allows the mobile station to use a low power mode at times outside of the scheduled service periods. However, the mobile station may occasionally need to retrieve additional data from the access point, or transmit additional data to the access point, and so initiates an unscheduled service period to do so.

摘要： A mobile terminal (302, 304) wakes up from a low power state and initiates a frame exchange in a wireless local area network that supports voice traffic by transmitting a polling frame (602). If the mobile terminal had voice data to send, it is included in the polling frame. In response to receiving the polling frame, the access point transmits a delay frame (604) to acknowledge receipt of the polling frame. If the access point has data for the polling mobile terminal, it transmits a non-delay frame (606) including the voice data, otherwise it transmits a null frame (702). The mobile terminal acknowledges the data from the access point (608), and goes back to sleep until the beginning of the next service interval.
摘要翻译：移动终端（302,304）从低功率状态唤醒，并通过发送轮询帧（602）在支持话音业务的无线局域网中发起帧交换。如果移动终端具有要发送的语音数据，则它被包括在轮询帧中。响应于接收到轮询帧，接入点发送延迟帧（604）以确认轮询帧的接收。如果接入点具有轮询移动终端的数据，则它发送包括语音数据的非延迟帧（606），否则发送空帧（702）。移动终端从接入点（608）确认数据，并返回睡眠直到下一个服务间隔的开始。

摘要： A wireless local area network (WLAN) includes an access point (102) and a mobile station (106). The mobile station can operate in a low power mode by shutting down a WLAN subsystem (204) of the mobile station. While the mobile station is in a low power mode, the access point buffers data received at the access point destined for the mobile station (706). The mobile station wakes up to initiate a service period by transmitting a trigger frame to the access point, and identifies a traffic stream to be serviced in the presently initiated service period. The access point begins transmitting response frames to the mobile station, identifying the traffic stream requested by the mobile station, and in at least one response frame, the access point may indicate the buffer status of another traffic stream associated with the mobile station to allow the mobile station to make decisions regarding data retrieval and power save state.

摘要： Multi-mode link adaptation in a wireless communication network where a station calculates a current link quality, a minimum link quality, and an excess link quality based upon the current link quality and the minimum link quality to determine an operating mode that is related to the success or failure of recent transmissions from the station. If the calculated excess link margin is lower than a first threshold, the station operates in a first mode, otherwise in another mode. In any case, the station selects the link rate for a new transmission from the station based upon the selected mode.

摘要： The proposed method and apparatus reduces an amount of power required for nodes to both transmit and receive messages. In particular, broadcast packets are sent in an awake period (ATIM window) if the length of these messages is small. Because these packets do not need acknowledgment or they do not expect immediate reply, they may be broadcast in the ATIM window. Since all nodes are awake during the ATIM window, nodes may receive messages during this period of time which they ordinarily would need to stay awake to receive in the sleep period (post ATIM window).
摘要翻译：所提出的方法和装置减少了节点发送和接收消息所需的功率量。特别地，如果这些消息的长度较小，则在清醒周期（ATIM窗口）中发送广播分组。由于这些数据包不需要确认或者不希望立即回复，所以可以在ATIM窗口中进行广播。由于所有节点在ATIM窗口期间都处于唤醒状态，所以节点可能会在这段时间内接收消息，通常在休眠期间（ATIM窗口）通常需要保持唤醒状态。

摘要： A method and apparatus for mutual authentication of a first and a second node is provided herein. During operation the first node sends a first authentication message to the second node comprising information needed for the second node to authenticate the first node and information needed by the second node for the second node to be authenticated by the first node. A second authentication message is received from the second node comprising information needed by the first node for the first node to be authenticated by the second node and information needed for the first node to authenticate the second node. Because the first and the second authentication messages comprise information needed for both the first and the second node to authenticate each other, messaging within the network is greatly reduced.
