Abstract: A method, apparatus and computer program product for the express forwarding are presented. A timer (NAV) is maintained at each respective node of a wireless LAN. A frame is designated as a TSQ frame to be express forwarded from a first node to a second node. A duration field of the frame is incremented by a first predetermined time increment (DT0) before the TSQ frame is forwarded and the TSQ frame is forwarded by the first node to the second node. A response is received from the second node wherein non-forwarding neighboring nodes each set their NAV according to a value equal to the duration field of the response. The second node attempts transmission of the TSQ frame when acknowledgement of receipt of the TSQ frame is complete.

Abstract: Spectrum monitoring measurements are made by microcell base stations in a layered cellular network, while not serving calls or engaged in processing calls. The microcell base station transmits a first control message from to a microcell mobile station, to increase the duration for the mobile station to reside in the camping state on a control channel of the microcell base station. The microcell base station transmits a second control message from the microcell base station to the microcell mobile station, to increase the duration for the mobile station to reside in a call origination state while attempting to access a control channel of the microcell base station. Then, to perform the spectrum monitoring measurement, the base station's transmitter is turned off, the receiver is retuned to the frequency to be monitored, a signal strength measurement taken on that frequency, the receiver is retuned back to its assigned frequency, and the transmitter is turned back on, all in a short time interval. Because the measurement time is so short, it is possible to take spectrum-monitoring measurements without causing inactive mobiles registered on the measuring base station to reselect control channel. Mobiles initiating a call during a spectrum monitoring measurement by its base station are also delayed in their control channel reselection.

Abstract translation: 频谱监视测量由分层蜂窝网络中的微蜂窝基站进行，而不提供呼叫或从事处理呼叫。 微小区基站向微小区移动台发送第一控制消息，以在微小区基站的控制信道上增加移动站驻留在驻留状态的持续时间。 微小区基站从微小区基站向微小区移动台发送第二控制消息，以增加移动台驻留在呼叫发起状态的持续时间，同时尝试接入微小区基站的控制信道。 然后，为了执行频谱监测测量，基站的发射机被关闭，接收机被重新调谐到待监视的频率，在该频率上进行的信号强度测量，接收机被重新调回其分配的频率，并且发射机 被重新打开，全部在短时间内。 由于测量时间如此之短，可以进行频谱监测测量，而不会导致测量基站上登记的无效移动台重新选择控制信道。 在其基站进行频谱监测测量期间发起呼叫的移动台在其控制信道重选中也被延迟。

Abstract: An access point transmits a preemptive peg packet when it has no data to transmit in order to maintain the contiguity of its transmission timing position with respect to the timing position of other contention-free sessions (CFS) transmitted by other access points in an existing, periodic sequence. The cyclic prioritized multiple access (CDMA) method establishes the transmission timing position of contention-free sessions (CFS) between overlapping first and second wireless LAN cells contending for the same medium. Each cell includes a respective plurality of member stations. If an access point has no traffic, it will transmit a short, preemptive pegging packet and reset its backoff timer. In this manner, no gaps longer than the distributed coordination function (DCF) Interframe Space (DIFS) are left idle. This prevents other stations from using DCF contention to seize the channel, until all access points have completed one contention-free session (CFS) per periodic cycle.

Abstract: A method of providing power management in a Wireless Local Area Network (WLAN) is presented. The method includes receiving a Traffic Indication Map (TIM) at a station, indicating the presence of buffered frames, associated with any AC, for the station at an Access Point (AP). The method further includes sending, by the station, one of an uplink data frame if one is buffered, and a null frame to retrieve the buffered frames from said AP. The station remains awake to receive frames from the AP until a downlink frame is received containing an indication that it is the last frame to be transmitted in the service period. The method may further include determining at the end of service period whether there are more frames remaining buffered for the station at the AP.

Abstract: A method, apparatus and computer program product for providing collision avoidance and/or channel capture is presented. A timer (NAV) for a channel which, if set, prevents the node from transmitting on the channel is maintained at a station. A determination is made whether a duration of a transmission response (CTS) has expired. The NAV is cleared when the channel is idle for a predetermined time interval and the flag is clear, and the NAV is not cleared when the flag is set.

Abstract: A method, apparatus and computer program product for using a single-radio node and a multi-radio node in a wireless network having a control channel and at least one data channel is presented. One radio of the multi-radio node is kept tuned to the control channel. The single-radio node and the multi-radio node release the control channel at a predetermined time. Further, the data channels used by the single-radio nodes are released at the predetermined time. In such a manner single-radio and multi-radio nodes can co-exist harmoniously in wireless networks with increased bandwidth utilization and efficiency.

Abstract: A method, apparatus and computer program product for performing dynamic channel assignment in wireless ad hoc networks (wireless mesh and infrastructure BSSs) is presented. A fixed channel assignment order is determined for each link of the network, the fixed channel assignment order enabling simultaneous transmission without co-channel interference. A preference order is loaded for a node, the preference order derived from the fixed channel assignment order. A channel is selected in accordance with the preference order when a node is ready for transmission. A determination is made whether the selected channel is available, and when the selected channel is available then the node transmits on the channel and when the selected channel is not available then a next channel in the preference order is selected for the node and the determination regarding whether the selected channel is available is repeated.

Abstract: An apparatus and method for informing a coordinator of the particular characteristics of a periodic traffic source are disclosed. A station that generates a periodic traffic stream encodes the temporal period and temporal offset of the traffic stream within a quality-of-service (QoS) traffic specification, and transmits the traffic specification with a poll request. The coordinator, upon receiving a polling request, processes the associated traffic specification and, via appropriate decoding logic, determines whether the requesting station generates periodic traffic, and if so, the temporal period and temporal offset of the traffic stream. The coordinator subsequently can establish, based on the temporal period and temporal offset, a polling schedule that minimizes the delay between (i) the station generating a frame, and (ii) the station transmitting the frame (and thus the destination receiving the frame).
