摘要： Embodiments of the disclosure relate to operational association between communication devices in the presence of a link-budget imbalance between an upstream link and a downstream link at one of the communication devices. The association relies on a request for a narrowband resource block sent form the communication device having the link-budget imbalance to a remote communication device that can schedule and/or allocate the narrowband resource block. The request can be modulated according to an on-off keying modulation scheme or can be encoded according to a multi-repetition encoding scheme. In response to the narrowband resource block being allocated, an association request can be sent to the remote communication device in the narrowband resource block.

摘要： An approach is provided for defining a 1 MHz preamble of a packet. The approach involves determining a preamble sequence of a packet, the preamble sequence having a determinable length. The approach also involves causing, at least in part, the preamble sequence to be divided into a predetermined number of blocks. The approach further involves causing, at least in part, a mathematical operation and a summation over the predetermined number of blocks and a corresponding number of received blocks. The approach also involves causing, at least in part, the summation to be maximized to determine the preamble sequence corresponds to one of a first bandwidth or a second bandwidth, the second bandwidth being greater than the first bandwidth, to determine a type of the packet.

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： A high-efficiency wireless local-area network (HEW) device including physical layer and medium access control layer circuitry is disclosed. The physical layer and medium access control layer circuitry may be configured to encode data with a binary convolutional code (BCC) to generate encoded data, and interleave the encoded data in accordance with one of a plurality of interleaver configurations for one of a predetermined number of data subcarriers to generate interleaved encoded data. The physical layer and medium access control layer circuitry may be further configured to map the interleaved encoded data with a quadrature amplitude modulation (QAM) greater than 256 QAM onto longer-duration orthogonal frequency division multiplexed (OFDM) symbols, and transmit the longer-duration OFDM symbols on channel resources in accordance with an orthogonal frequency division multiple access (OFDMA) technique. The channel resources may be resource allocations with each resource allocation including the one of the predetermined number of data subcarriers.
