摘要： A method of providing RF signal quality information which includes the step of a probe request generator (110) monitoring a channel for probe requests being transmitted by a station (115) and/or probe responses being transmitted by an access point (105). The probe request generator can determine a time period between the successive probe request transmissions received from the station or successive probe responses received from the AP. The probe request generator can generate a series of probe requests (150) having the determined time period between successive probe request transmissions. The series of probe requests signal an access point (105) to transmit probe responses (155) which are detectable by the station.

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 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： 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 communication unit (10) can have at least a first receiver (11) and a second receiver (12). The latter typically consumes more power than the former during ordinary operation. Pursuant to one embodiment a communication unit can use the lower-power receiver to detect energy on a monitored channel while the second receiver is retained in a reduced power mode of operation. Upon detecting an absence of channel activity the second receiver can be restored to normal operability to effect such activities as are then presently required.
