Abstract
Wireless devices, methods, and computer readable media are disclosed. A high-efficiency wireless local-area network (HEW) master station is disclosed. The HEW master station may include circuitry. The circuitry may be configured to generate one or more resource allocations of a bandwidth for one or more HEW stations. Each resource allocation for a first portion of the bandwidth may be a multiple of a basic resource allocation or the entire first portion of the bandwidth. There may be only one resource allocation for a second portion of the bandwidth that is at least as large as the first portion of the bandwidth. In some embodiments, each resource allocation for the second portion of the bandwidth may be a multiple of the basic resource allocation or the entire second portion of the bandwidth.
