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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Master station and method for high-efficiency Wi-Fi (HEW) communication using a multiple access technique","description":"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.
