摘要： Logic may determine a first frame comprising a hopping pattern value and a target hopping time (THT). The hopping pattern may indicate a pattern of channels to which to hop. Logic may determine a clear-to-send (CTS) frame comprising a duration value indicative of a duration of a data transmission. Logic may transmit the first frame on at least a primary channel of the channels. Logic may transmit the CTS frame prior to transmitting the data transmission on the one or more channels in accordance with the hopping pattern, each channel having a bandwidth of at least 450 megahertz and being within in a 6 gigahertz to 10 gigahertz frequency band. Logic may receive a frame on at least a primary channel of the channels. Logic may receive CTS frames at the THT in accordance with the hopping pattern.

摘要： Logic such as hardware and/or code to narrow available sub-channels in frequency selective transmission communications in which a station selects a narrow band from a wider channel bandwidth. A frequency selective transmission scheme for communications devices may select a 1 or 2 MHz channel from a wider channel bandwidth (e.g., 4, 8, 16 MHz) that consists of a number of 1 or 2 MHz sub-channels and transmitting packets on the selected sub-channel. The access point may narrow the number of sub-channels available for selection by stations. Stations may narrow the number of sub-channels. Both the AP and the stations may operate to narrow the number of sub-channels. A medium access control sub-layer protocol common to the communications devices may facilitate a frequency selective transmission scheme.

摘要： A system and method are provided for implementing improved frequency estimation for wireless communication that involves lower power transmissions with reduced signal-to-noise ratios for receivers particularly in systems configured according to the pending IEEE 802.11ah standard. These systems and methods provide frequency estimation over that prescribed for devices operating according other IEEE 802.11 standards and the proposed frequency estimator specified for IEEE 802.11ac systems. The disclosed techniques use schemes that reuse a short training field (STF) stored in memory, employ joint STF-long training field (LTF) estimation, use portions of a guard interval (GI), and create of multiple-phase estimates, with different symbol separation to improve a signal-to-noise ratio of the frequency estimate.

摘要： Embodiments of an access point (AP), user station (STA), and method for variable length encoding are generally described herein. The AP may encode a block of input bits according to a parity check matrix to produce a low density parity check (LDPC) codeword. The parity check matrix may be included in a group of candidate parity check matrixes that includes a base parity check matrix and an expanded parity check matrix. An LDPC codeword length may be smaller for the base parity check matrix than for the expanded parity check matrix. The base parity check matrix may be used for the encoding when the LDPC codeword is transmitted for a legacy user station (STA). The expanded parity check matrix may be used when the LDPC codeword is transmitted for a non-legacy STA.
