Embodiments of a station (STA) and method of communication are generally described herein. The STA may be included in a first plurality of STAs affiliated with a first multi-link logical entity (MLLE). A plurality of links may be established between the first MLLE and a second MLLE, wherein the second MLLE may be affiliated with a second plurality of STAs. The STA may receive a first subset of a sequence of MAC protocol data units (MPDUs). A second subset of the sequence of MPDUs may be transmitted by another STA of the first plurality of STAs. The STA may transmit a block acknowledgement (BA) frame that includes: a number of BA bitmaps, configurable to values greater than or equal to one; and BA control information for each of the BA bitmaps.

Block acknowledgement and fragmentation in multi-link communication between multi-link logical entities

Embodiments of the present disclosure provide for implicit channel tracking for simultaneous multiuser transmissions. Other embodiments may be described and claimed.

Implicit channel tracking for simultaneous multiuser transmission

Multiple of first packets of at least partially different lengths are aggregated into a sequence of subframes of a second packet. The second packet is transmitted via a radio channel.

Communication device and method

Methods, apparatuses, computer readable media for uplink transmission power control in a wireless network. An apparatus of a wireless device comprising processing circuitry is disclosed. The processing circuitry is configured to decode a trigger frame from an access point for an uplink communication, the trigger frame comprising an uplink resource allocation for the station, the uplink resource allocation including common information and per station information, the common information including an indication of a maximum receive power at the access point, the per station information comprising an identification of the station, and an indication of a resource unit (RU). The processing circuitry may be further configured to: encode an uplink (UL) physical layer convergence procedure (PLCP) protocol data unit (PPDU)(UL-PPDU) in accordance with the indication of the RU. The processing circuitry may be further configured to: determine a transmit power for the UL-PPDU based on the maximum receive power.

Transmit power control for uplink transmissions

Disclosed is a method of multiuser uplink power control comprising receiving a multiuser uplink calibration transmission from a plurality of stations; grouping the plurality of stations into a plurality of subsets based on a subset characteristic; receiving a subset optimization transmission from a first subset according to a subset rule; and calculating a first calibrated coding data rate and a first calibrated target uplink transmit power for a station in the first subset based on the subset optimization transmission.

Multiuser uplink power control with user grouping

Apparatuses, computer readable media, and methods for uplink sounding in wireless networks are disclosed. An apparatus of a wireless device may include processing circuitry configured to: encode an uplink sounding trigger element (USTE) for one or more stations, the USTE comprising one or more uplink (UL) resource allocations for the one or more stations to transmit one or more uplink sounding referee elements (USREs) to the wireless device. The processing circuitry may be further configured to configure the wireless device to transmit the USTE to the one or more stations, and decode the one or more USREs from the one or more station, wherein the one or more USREs are to be received by the wireless device in accordance with a corresponding resource allocation indicated in the USTE.

Uplink sounding in wireless networks

System and techniques for multi-phase wireless sounding are described herein. A first set of stations may be selected by an access point from a plurality of stations known to the access point. The access point may then transmit a first sounding request to members of the first set of stations. The access point may receive a sounding report in response to the first sounding request from members of the first set of stations. The access point may then select a second set of stations from the plurality of stations based on the sounding report. This second set of stations is a proper subset of the first set of stations. The access point may then transmit a second sounding request to the second set of stations.

Multi-phase wireless sounding

Embodiments of an access point (AP), station (STA) and method for uplink sounding are generally described herein. The AP may transmit an uplink (UL) sounding trigger frame (TF) that indicates a request to receive UL sounding elements from a group of one or more stations (STAs). The AP may receive UL sounding elements from the STAs in accordance with UL multi-user multiple-input multiple-output (MU-MIMO) reception. The AP may also receive, from at least a portion of the STAs, UL sounding feedback that includes one or more UL sounding transmission parameters used by the portion of the STAs for UL sounding element transmissions. The UL sounding TF may further indicate the portion of the STAs that are to transmit the UL sounding feedback.
