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 (706) or a gratuitous probe response (710) 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 (204) in a wireless local area network is associated with an access point (202), which controls timing of certain transmissions, such as beacons (402). The mobile station has a timer (108) that is driven by a high frequency clock source (110) while operating in an active mode, and a low frequency clock source (112) when in a low power mode, to conserve battery charge. To prevent timing errors from significantly affecting the accuracy for the timer (108) upon transitioning from one mode to the other, access point transmits timing information to the mobile station in the course of servicing requests from the mobile station. The timing information is included in a response sequence (300).
摘要翻译：无线局域网中的移动台（204）与控制诸如信标（402）的某些传输的定时的接入点（202）相关联。当处于低功率模式时，该移动台具有由高频时钟源（110）驱动并且在低功率模式下工作的定时器（108）和低频时钟源（112），以节省电池电量。为了防止定时错误在从一个模式转换到另一个模式时对定时器（108）的准确性产生显着影响，接入点在处理来自移动站的请求的过程中向移动台发送定时信息。定时信息被包括在响应序列（300）中。

摘要： A method and a machine readable storage for handling failures during security exchanges between a station (125) having a wireless network adapter (130) and a first access point (110) of a wireless local area network (WLAN) (105). As part of a WLAN association process, the method can include transmitting from the station to the first access point a message including a station identifier (170). A first protocol exchange timer (180) also can be started. Responsive to a timeout of the first protocol exchange timer, an association retry counter can be incremented. The WLAN association process can be restarted if the association retry counter is not greater than a retry counter threshold. If the association retry counter is greater than the retry counter threshold, the wireless network adapter can be commanded to enter sleep mode.

摘要： A wireless station (114) is within range of more than one access point (120, 124) transmitting on the same channel. The wireless station is associated with one access point and not the other. Consequently the wireless station may receive undesired beacons (304) and desired beacons (302) on the channel. To optimize power save operation the wireless station arbitrates between a scan and shut down scanning procedure (708) and a timed window channel scanning procedure (724), depending on whether the desired beacon is the first received beacon upon waking up from a low power state at a target beacon time.

摘要： A wireless local area network (WLAN) mobile station (110, 112, 114) has an application processor core (204) and a WLAN processor (202). So as to conserve energy, when the two processors are not needed, they are both placed in a minimal power consumption mode. The WLAN processor operates a WLAN radio and receives beacon transmissions from an access point (120). Upon extracting the beacon data from a received beacon signal, the WLAN processor passes the beacon data to the application processor. To ensure receipt of the beacon data, the WLAN processor remains active until the application processor acknowledges receipt of the beacon data before transitioning back to a sleep mode. To prevent keeping the WLAN processor waiting longer than necessary, the application processor wakes up ahead of the beacon receipt time, in time to allow transition to an awake mode so that it is active by the time the WLAN processor passes the beacon data.
摘要翻译：无线局域网（WLAN）移动站（110,112,114）具有应用处理器核心（204）和WLAN处理器（202）。为了节省能源，当不需要两个处理器时，它们都被放置在最小的功耗模式中。 WLAN处理器操作WLAN无线电并从接入点（120）接收信标传输。在从接收的信标信号中提取信标数据之后，WLAN处理器将信标数据传送到应用处理器。为了确保信标数据的接收，WLAN处理器保持有效，直到应用处理器在转换回睡眠模式之前确认信标数据的接收。为了防止WLAN处理器等待更长时间，应用处理器在时间之前唤醒信标接收时间，以允许转换到唤醒模式，使其在WLAN处理器通过信标数据时被激活。

摘要： A processor (1104) receives a baseband signal including a plurality of symbols, and determines (1002) a maximum modulation level and a minimum modulation level in the baseband signal through a modified self-organizing map clustering technique. The processor initializes (1008) a plurality of clusters (700, 800) corresponding to the plurality of modulation levels, based upon the maximum and minimum modulation levels; and processes (1010), through a modified adaptive k-means clustering technique, a symbol value corresponding to each of the plurality of symbols by updating (1012) parameters maintained for a cluster of the plurality of clusters, the cluster having a cluster mean value within a modulation-specified distance from the symbol value. The processor calculates (1014) a plurality of statistical values from the parameters maintained for the plurality of clusters, and classifies (1016, 1018, 1020) the baseband signal, based upon the plurality of statistical values and the parameters.
