A HEW station is disclosed that may include circuitry configured to receive a trigger frame with a first duration from a HEW master station, determine a second duration based on the first duration, generate a packet with the second duration, and transmit the packet with the second duration in an uplink transmission opportunity to the master station in accordance with at least one from the following group: orthogonal frequency division multiple-access and multiple-user multiple-input multiple-output. The trigger frame may include a resource map and the HEW station may transmit the packet on a channel indicated in the resource map.

Abstract: Wireless device, computer readable medium, and methods for signaling a resource allocation in a high-efficiency (HE) signal field are disclosed. A HE wireless local area network (HEW) device may include circuitry configured to: generate a HE signal (HE-SIG) field comprising one or more resource allocations each comprising an identical allocation subfield, an allocation or no allocation subfield, if the identical allocation subfield indicates the resource allocation is not identical, an allocation size if the identical allocation subfield indicates the resource allocation is not identical, and a station identification (ID), if the allocation or no allocation subfield indicates there is an allocation. The circuitry is further configured to transmit the HE-SIG field to one or more HEW stations. The allocation size may be based on a number of basic allocation units. The resource allocations may be allocated from a left side of a bandwidth to a right side of a bandwidth.

Abstract: Methods and devices are described for providing wireless stations (STAs) with two sets of enhanced distributed channel access (EDCA) parameters. Legacy EDCA parameters that are for single user (SU) operations and may be used by both high-efficiency (HE) STAs and legacy STAs without multi-user (MU) capability. MU EDCA parameters are defined to be more restrictive than legacy EDCA parameters in favoring MU operations. Embodiments are described that define sets of rules for regulating how STAs capable of both SU and MU uplink operations can use the different sets of EDCA parameters.
