摘要： Embodiments may implement a hierarchical data structure for traffic indication mapping. Many embodiments facilitate establishing a number of pages and a number of blocks per page in a bitmap structure. For instance, several embodiments may determine a number of pages (Np) and a number of blocks per page (Nb) in the bitmap structure and communicate these to a station to facilitate communication of TIM elements to the station by an access point. In several embodiments, an access point may determine the number of pages and number of blocks per page and may transmit these numbers to stations as the stations associate with the access point such as in association response frames. In further embodiments, the access point may dynamically change the number of pages and/or the number of blocks per page by transmitting a TIM element to the stations in a beacon frame.

摘要： A device for communicating in a wireless network, such as, for example, a non-AP STA, is adapted to send a trigger frame to an AP for group-addressed frames. In addition, an AP may be adapted to be triggered for group-addressed frames to deliver the group-addressed frame to a non-AP STA. The group-addressed frames could include data frames or management frames or both. Such a device or non-AP STA can advantageously stay in a power save mode until it is ready to wake up to send a trigger frame to the AP, and does not need to wake up at regular intervals, such as at every DTIM time interval, to listen for beacons from the AP and to receive any group-addressed frames destined for it and buffered at the AP. In this way, the battery life of the device may be extended.

摘要： Embodiments of a user station (STA) and methods for device-to-device discovery and advertisement through broadcast beacon signals are generally described herein. In some embodiments, group information, including a list of STAs in an advertising group, is transmitted in a beacon. A STA may transmit a request to join the advertising group. The request may be transmitted to an upchain STA, the upchain STA being determined based on inspection of the list of STAs of the advertising group. After receiving a response to the request, the STA may periodically broadcast the beacon and the STA may transmit acknowledgements to the upchain STA upon receiving beacons from the upchain STA.

摘要： Embodiments of a multi-radio controller and methods for preventing interference between co-located transceivers are generally described herein. In some embodiments, the multi-radio controller operates within a multi-radio device and is configured to cause a wireless local area network (WLAN) transceiver to transmit a triggering frame after an active period of a wireless wide-area network (WWAN) transceiver. The triggering frame indicates the duration of a transmission opportunity, which may be restricted to the time between active periods of the WWAN. In response to receipt of the triggering frame, the WLAN access point is configured to transmit a downlink data frame within the transmission opportunity.

摘要： Logic may implement an orthogonal frequency division multiplexing (OFDM) system operating in the one gigahertz and lower frequency bands. Logic may detect new long training sequences that are differentially orthogonal to each other for a first bandwidth mode of operation such as a one megahertz mode as well as differentially orthogonal to half of the long training sequence for a second bandwidth mode of operation such as a two megahertz or greater mode. Logic may implement two or more long training sequences for the first bandwidth mode of operation to transmit information based upon the selection of the particular long training sequence for the transmission. Logic may implement a new acknowledgement packet comprising a short training sequence and a long training sequence without a signal field and without a payload. And logic may implement bandwidth detection logic to classify a transmission based upon orthogonal properties of the long training sequences.

摘要： Embodiments of a very-high throughput communication station and method for communicating on a primary channel and up to three or more secondary channels are generally described herein. Short-preamble detection may be performed during a contention window to detect packet transmissions on any one of the secondary channels starting within the contention window. Guard-interval detection is also performed during the contention window to detect a guard interval of a packet transmission on any one of the secondary channels. The short-preamble detection and the guard-interval detection may be performed concurrently during the contention window to determine if any of the secondary channels are busy.

摘要： When a wireless communications device intends to communicate with another device over a wide channel consisting of multiple narrow channels, but detects interference on one or more of those narrow channels, it may restrict subsequent communications with that other device to those narrow channels that don't suffer from the interference. In one embodiment the device may simply refuse to monitor the interfering channel(s) for signals for a particular period of time. In another embodiment the device may use a CTS to signal the other device not to use the interfering narrow channel(s). That may result in using a wide channel with a reduced bandwidth for communications.

摘要： When a device is contending for the right to transmit on a wide channel (composed of a primary narrow channel and one or more secondary narrow channels), it may halt its backoff counter if one of the secondary channels is detected as busy, and restart the backoff counter from its halted value when all the channels are again detected as idle. Some embodiments may use a guard interval detection technique to aid in sensing whether the secondary channels are busy.

摘要： A nonvolatile memory device includes resistive memory devices in a three-dimensional structure. A block select circuit generates a block select signal for selecting a memory block. In response to the block select signal, local word line selection units connected to each memory block connect global word lines connected to a word line decoder and local word lines, and local bit line selection units connected to each memory block connect global bit lines connected to a sense amplifier and local bit lines. Each memory block includes local word lines which extend in a first direction and are stacked in a second direction perpendicular to the first direction on a second plane perpendicular to a first plane. Local bit lines extend in the second direction to cross local word lines. Memory cells are formed at cross-points where local word lines and local bit lines cross one another.
