Abstract: Uplink requests for bandwidth and/or other types of communication resources are provided. In some embodiments, a communication device can access a mapping between quality of service (QoS) metrics and communication resources. The communication device can determined a value of the QoS (e.g., a guaranteed rate, a defined traffic priority, an amount of buffered data, etc.) and can determine a communication resource element using at least the mapping and the value of the QoS metric. The communication device also can configure an uplink request for communication resources based at least on the communication resource element. In addition, the communication device can send the uplink request.

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).

Abstract: This disclosure describes systems, methods, and apparatus related to a restrictive target wake time (TWT) service period (SP) system. A device may determine a beacon frame to be sent to one or more power save devices. The device may determine a time duration of a TWT SP associated with the one or more power save devices. The device may determine a first trigger frame including a cascade indication. The device may determine a first time associated with the first trigger frame. The device may cause to send the trigger frame to the one or more power save devices based at least in part on a remaining duration of the TWT SP.

Abstract: Embodiments of an access point (AP), a user station (STA), and a method for range estimation in a wireless network are generally described herein. For example, the AP may encode a common information field of a first trigger frame to include a trigger frame type configured to check the readiness of associated and unassociated STAs. The AP may transmit the first trigger frame to STAs and receive feedback from the STAs. The AP may further encode, based on the feedback, a common information field of a second trigger frame to include one of: a trigger frame type that solicits negotiation packets from associated and unassociated STAs using an association identifier (AID) and a pre-AID; or a trigger frame type that solicits channel sounding packets from associated and unassociated STAs using an AID and a pre-AID. The AP may further transmit the second trigger frame to the STAs.

Abstract: New wireless networks can perform enhanced beamforming training for a multiple access technique, such as orthogonal frequency division multiple-access (OFDMA). The configurations of the stations and the networks presented herein provide a multiple-station beam refinement protocol (MSBRP) that may be used to train the transmit end and/or the receive end for the stations in a dense wireless local area network (WLAN). The MSBRP can have at least two phases. The first phase concurrently trains the receive side of multiple responder stations from one set of training signals sent from an initiator station. Then, each responder station can send training signals to the initiator station in a set of ordered phases associated with each responder station. The MSBRP eliminates inefficiencies associated with conducting multiple BRPs that include only pairs of stations.
