Abstract

Apparatuses, methods, and computer readable media for resource allocation are disclosed. A high-efficiency wireless local-area network (HEW) master station is disclosed. The HEW master device may include circuitry configured to generate one or more resource allocations for each station of a plurality of stations. Each resource allocation may include an address of a corresponding station, a channel index to indicate a channel of a plurality of pre-defined channels of a bandwidth, and a sub-channel index to indicate the sub-channel bandwidth. If the sub-channel bandwidth is less than 20 MHz, each resource allocation includes a sub-channel location to indicate a sub-channel out of the multiple sub-channels of the indicated sub-channel bandwidth. The one or more resource allocations may be for a transmission opportunity in case of non-contiguous resource allocations for a single station. The circuitry may be further configured to operate in accordance with orthogonal frequency division multiple access (OFDMA).
