Abstract: Embodiments of a master station and method for communicating with a plurality of high-efficiency Wi-Fi (HEW) devices in a wireless network are generally described herein. In some embodiments, the master station may contend for a wireless medium during a contention period to receive control of the medium for an HEW control period, and transmit an HEW control and schedule transmission at the beginning of the HEW control period. The HEW control and schedule transmission may include a schedule indicating channel resources for communications with the HEW devices during the HEW control period in accordance with a non-contention based multiple access technique. The channel resources indicated in the HEW control and schedule transmission may comprise subspaces within a wideband legacy channel bandwidth. Transmissions on HEW channels during the HEW control period may have symbol times aligned within each legacy channel for legacy-device coexistence.

Abstract: Methods, devices, and systems for retransmission of wake-up signals from a first station to a second station over a wireless network are disclosed. In some aspects, a wake-up signal is encoded for transmission to the second station. While the first station is waiting for an acknowledgment of the wake-up signal from the second station, the second station may retransmit the wake up signal and/or encode a packet for transmission to a third station. In some aspects, whether the wake-up signal is retransmitted is based in part, on at least one of whether a number of timeout events for wake-up signals transmitted to the second station exceeds a maximum timeouts threshold, whether a number of wake-up signals transmitted to the second station exceeds a maximum wake-up signals threshold; or whether a maximum predetermined elapsed time since a first wake-up signal was transmitted to the second station is exceeded.

Abstract: 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.
