Abstract: Devices and methods of limiting wideband STA communication are generally described. The STA receives, over a primary channel, a wakeup frame containing an indication of a SP or CBAP to acquire a wideband TXOP over a wide bandwidth channel including the primary channel and a secondary channel and a control trailer having an indication of the wide bandwidth channel. Prior to the SP/CBAP, the STA opens reception from the primary channel to the wide bandwidth channel. The STA then communicates with another STA over the wide bandwidth channel and subsequently reduces reception from the wide bandwidth channel to the primary channel. The wakeup frame originates from an AP/PCP or the other STA, and contains fields indicating the wakeup frame length and SP or a sensing time length prior to the CBAP.

Abstract: This disclosure describes systems, methods, and devices related to enhanced multiple-input multiple-output (MIMO) beam refinement protocol (BRP) transmit sector sweep (TXSS). A device may establish a first communication link using a first antenna transmit chain of one or more transmit chains of the initiator, wherein the one or more antenna transmit chains further comprise a second antenna transmit chain. The device may initiate a MIMO BRP TXSS over the one or more antenna transmit chains. The device may map a single space-time stream over the one or more antenna transmit chains. The device may cause to send, to a responder device, an enhanced directional multi-gigabit (EDMG) frame using spatial expansion based on the mapping of the single space-time stream. The device may identify a feedback frame from the responder device. The device may determine one or more antenna weight vectors (AWVs) to use in a MIMO phase of the MIMO beamforming training based on the feedback frame.

Abstract: Apparatus, computer readable media, and methods for enhanced beamforming training in a wireless local area network are disclosed. An apparatus of a access point or station is disclosed. The apparatus including processing circuitry where the processing circuitry is configured to encode an EBRP packet comprising a first portion comprising an indication of a first number of transmit antenna training settings (N-TX), and an indication of a second number of receive training subfields per N-TX settings (N-RX), and a second portion comprising a third number of training subfields. The third number may be less than or equal to N-TX times N-RX. The processing circuitry may be configured to cause the first portion of the EBRP packet to be transmitted and cause the second portion to be transmitted, where two or more of the third number of training subfields are to be transmitted simultaneously using different antennas and orthogonal sequences.

Abstract: Embodiments of an enhanced directional multi-gigabit (EDMG) station (STA), access point (AP), and method of communication are generally described herein. The EDMG STA may receive, from the AP, a Link Measurement Request Frame that includes a request for information for time division duplexing (TDD) rate adaptation. The EDMG STA may transmit a Link Measurement Response Frame that includes a Directional Multi Gigabit (DMG) Link Margin element that includes a Rate Adaption Control parameter. The DMG Link Margin element may be configurable to include one or more optional fields for the TDD rate adaptation and transmit power control. The Rate Adaptation Control parameter may indicate: a number of space time streams (STSs) for which information is included in the DMG Link Margin element; and whether the DMG Link Margin element includes the one or more optional fields.

Abstract: Computer readable media, methods, and apparatuses for centralized channel access for primary and secondary channels are disclosed. An apparatus is disclosed comprising memory and processing circuitry. The processing circuitry is configured to encode a schedule of one or more resource allocations, wherein each resource allocation comprises a type of allocation, a bandwidth, an indication of a channel, a source association identification (AID), a destination AID, an allocation start, and a duration. The type of allocation may be a service period (SP) or a contention-based access period (CBAP). The channel may be an indication of a basic service set (BSS) or a personal BSS (PBSS) primary channel, BSS or PBSS secondary channel, or BSS or PBSS tertiary channel. The processing circuitry may be configured to transmit the schedule to one or more stations identified by the source AID and the destination AID of the one or more resource allocations.

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.

Abstract: Embodiments of a station (STA) and method for communication on primary and secondary channel resources are generally described herein. The STA may transmit a grant frame to indicate a transmission of a data payload by the STA during a grant period. The grant frame may indicate whether the data payload is to be transmitted on primary channel resources or on secondary channel resources. The STA may transmit the data payload to a destination STA on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources. The grant frame may be transmitted on the primary channel resources and on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources.
