    Abstract: Herein described are apparatuses, systems, and methods for measurement and reporting of channel state information within wireless network systems. In embodiments, an apparatus for a user equipment (UE) may include memory to store a rank indicator (RI), a precoding matrix index (PMI), and a channel quality indicator (CQI) of channel state information (CSI) for the UE. The apparatus may further include circuitry to concatenate the RI, the PMI, and the CQI to produce a concatenated CSI element, generate a CSI report that includes the concatenated CSI element, and cause the CSI report to be transmitted to a base station within a single slot. Other embodiments may be described and/or claimed.

    Abstract: Some aspects of this disclosure include an apparatus, method, and computer program product for wireless local area network (WLAN) link adaptation. Some aspects of this disclosure include fast feedback (FB) contents to improve WLAN link adaptation that can address the challenges of ultra-high reliability (UHR) wireless communications. Fast FB contents can include a feedback sequence number (FBSN) that identifies a reference packet and FB data corresponding to the receipt of the reference packet by the receiving device. The FB data can include link adaptation parameters corresponding to the receiving device that the transmitting device can use to adjust (e.g., adapt) subsequent transmissions to the same receiving device. Some aspects include an indicator that informs a receiving device whether to provide a Negative Acknowledgement (NACK) frame (e.g., control packets) with FB contents or not.

    Abstract: Some aspects of this disclosure include an apparatus, method, and computer program product for wireless local area network (WLAN) link adaptation for multi-user transmission. For example, a receiving device can receive a multi-user-physical layer (PHY) protocol data unit (MU-PPDU) including a preamble and a plurality of data portions. The preamble can include a PHY multi-user-block acknowledgement request (MU-BAR) frame indicating a frequency band for transmitting a trigger-based (TB)-PPDU. The receiving device can decode at least a portion of a first data portion of the and transmit the TB-PPDU including feedback (FB) data corresponding to the first data portion in the frequency band. Even if the decoding of the first data portion fails, the receiving device can use information in the PHY MU-BAR frame to transmit a TB-PPDU to the transmitting device that includes a negative acknowledgment (NACK) frame and a FB sequence number of the MU-PPDU.

    Abstract: Disclosed herein are apparatuses and a method for implementing latency reduction using preemption within a physical layer (PHY) protocol data unit (PDU) (PPDU). An embodiment operates by encoding a multi-user PPDU (MU-PPDU) for transmission, where, the MU-PPDU comprises a plurality of aggregated media access control (MAC) PDUs (A-MPDUs) addressed to respective non-low-latency stations (non-LL-STAs). Based on a determination that low-latency data addressed to a low-latency station (LL-STA) is available for transmission at a MAC layer of the AP, the embodiment then transmits a preemption-indicator signal to the LL-STA and at least one non-LL-STA. Further, the embodiment identifies an A-MPDU of the plurality of A-MPDUs that is scheduled for transmission over a resource unit (RU) designated for transmitting low-latency data. The embodiment then replaces at least one non-low-latency MPDUs (non-LL-MPDUs) associated with the A-MPDU with at least one low-latency MPDUs (LL-MPDUs) addressed to the LL-STA to generate an updated A-MPDU., where a first LL-MPDU of the plurality of LL-MPDUs is a multi-user block acknowledgment request (MU-BAR) frame associated with the LL-MPDUs. Finally, the embodiment transmits the updated A-MPDU consisting the at least one LL-MPDUs over the RU.
