摘要： This disclosure describes systems, methods, and devices related to enhanced bandwidth selection for wireless devices. A device may generate a request frame with at least one of a first indication of a bandwidth for which a second device is to measure a first noise level or a second indication of a resource unit for which the second device is to measure a second noise level. The device may send the request frame to the second device. The device may identify a response frame received from the second device, the response frame having a third indication of the first noise level or the second noise level and a fourth indication of the bandwidth or the resource unit. The device may determine, based on the first noise level or the second noise level, a parameter associated with a subsequent frame to send to the second device.

摘要： Embodiments of low-power wake-up packet generation are generally described herein. A wireless device modulates an LP-WUR (low-power wake-up radio) bit sequence with an LP-WUR pulse to obtain a plurality of modulated LP-WUR signals, each modulated LP-WUR signal having a 1× symbol duration. The wireless device multiplexes, in a time domain, an OFDMA (orthogonal frequency division multiple access) signal with a 4× symbol duration with four modulated LP-WUR signals, to generate a multiplexed signal. The wireless device encodes for transmission of the multiplexed signal to a peer device to wake up a WLAN (wireless local area network) radio of the peer device and to another device with an OFDMA signal.

摘要： Embodiments may implement a new hierarchical data structure for traffic indication mapping to facilitate transmissions for wireless communications devices. Many embodiments comprise MAC sublayer logic to generate and transmit management frames such as beacon frames with a partial virtual bitmap based upon the hierarchical data structure for traffic indication mapping. In some embodiments, the MAC sublayer logic may store the traffic indication map and/or the traffic indication map structure in memory, in logic, or in another manner that facilitates transmission of the frames. Some embodiments may receive, detect, and decode communications with frames comprising the partial virtual bitmap based upon the hierarchical data structure. In some embodiments, indications of buffered data for pages, super-blocks, blocks, sub-blocks, and/or stations may be inverted. In several embodiments, a new association identifier (AID) structure is defined for the new hierarchical data structure for traffic indication mapping.

摘要： Some embodiments provide a normal rate preamble detector to detect a signal transmitted in accordance with a first set of modulation and coding schemes and a low rate preamble detector to detect a signal transmitted in accordance with a second set of modulation and coding schemes. Embodiments may comprise channel traffic logic to determine a traffic indicator indicative of traffic on a communications channel. In many embodiments, channel traffic logic may comprise logic to determine a duty cycle of communications to determine the traffic indicator for the channel. In several embodiments, channel traffic logic may comprise logic to determine channel occupancy to determine the traffic indicator. Based upon the traffic indicator, channel traffic logic may determine whether to disable the low rate preamble detector.

摘要： Logic may transmit or receive communications that hop frequencies in response to trigger events across a large bandwidth. Logic may generate a communication with a contiguous or non-contiguous bandwidth based upon frequency segments of 80 MHz and/or 160 MHz. Logic may generate a communication with a contiguous bandwidth of 480 MHz. Logic may generate a communication with a non-contiguous bandwidth of 480 MHz. Logic may transmit or receive communications with a 480 MegaHertz (MHz) bandwidth that hop across a 3 GigaHertz (GHz) bandwidth of frequency channels. Logic may determine a channel-hopping pattern. Logic may hop frequency channels after each link transmission. Logic may hop channels after a fixed time interval. An logic may hop frequency channels in response to another triggering event.
