Abstract: For example, an apparatus may be configured to cause wireless communication station (STA) to set a cellular Quality of Service (QoS) index value in a cellular QoS index field to indicate a predefined setting of a set of a plurality QoS parameters for a cellular QoS traffic flow to be communicated by the STA over a Wireless Local Area Network (WLAN). For example, the apparatus may be configured to cause the STA to transmit a Stream Classification Service (SCS) request to an Access Point (AP) of the WLAN, the SCS request including an SCS descriptor element, the SCS descriptor element including the cellular QoS index field.

Abstract: Millimeter-wave (mmWave) and sub-mmWave technology, apparatuses, and methods that relate to transceivers and receivers for wireless communications are described. The various aspects include an apparatus of a communication device including an antenna array and processing circuitry coupled to the antenna array. The processing circuitry is configured to initialize a beam tracking algorithm based on received signals received at the antenna array, wherein antenna phases used in the beam tracking are bound by an upper phase limit and a lower phase limit, to generate a beam tracking result. The processing circuitry is further configured to generate a calibration vector based on the beam tracking result and receive subsequent transmissions using a codebook adapted based on the calibration vector.

Abstract: Systems, methods, and devices related to an EHT multi-AP group are described. The coordinated APs of the EHT group are synchronized to the coordinator AP using a periodic or non-periodic frame. Each coordinated AP then synchronizes STAs associated with the coordinated AP. In response to an MPDU, either triggered by a trigger frame from the coordinator AP or initiated by the STA, an ACK frame or NDP response is sent by each AP receiving the MPDU. The response to the MPDU is dependent on whether frame aggregation is used, as well as whether the trigger frame triggers transmission of MPDUs from multiple STAs.
