Abstract: Methods, systems and apparatuses for enhanced coordinated channel access including access points (APs) and non-access points (non-APs). A first non-access point (non-AP) in a group of at least two non-APs can receive, from a second non-AP of the group of at least two non-APs, signaling including information corresponding to a transmission opportunity (TXOP). Additionally, the first non-AP can transmit, in accordance with the information corresponding to the TXOP and scheduling information of the group of at least two non-APs, first data to one or more devices, wherein the first data is transmitted to the one or more devices in at least a portion of the TXOP.

Abstract: A method performed by a wireless device operating in an uplink multi-user mode includes: setting an exclusion bit in an operating mode control subfield of a transmit operating mode indicator frame, the exclusion bit indicating an exclusion of an AC or a TID from the uplink multi-user mode; sending, to the AP, a trigger-based physical layer protocol data unit (PPDU) comprising the transmit operating mode indicator frame; contending for channel access using an enhanced distributed channel access (EDCA) function to send the low latency data via an uplink; and transmitting the low latency data to the AP in a single user PPDU in accordance with EDCA-based channel contention.

Abstract: Disclosed are methods, systems, and computer-readable media configured to perform operations including: determining that an electronic device has at least one item to send to an access point (AP) or to another electronic device; encoding a trigger request message with information associated with the at least one item to be sent; and sending the trigger request message to the AP to request an uplink (UL) resource allocation or a peer-to-peer (P2P) resource allocation.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including detecting a reception opportunity of a physical layer protocol data unit (PPDU) scheduled to be transmitted by a transmitter, where the PPDU includes a preamble and one or more media access control (MAC) PDUs (MPDUs); decoding the preamble of the PPDU; detecting that reception of the one or more MPDUs has failed; and in response to the detecting, preparing a Negative Acknowledgment (NACK) message for transmission to the transmitter.

Abstract: Embodiments of a User Equipment (UE), a generation Node-B (gNB) and methods for communication are generally described herein. The UE may the UE 102 may receive from a gNB, control signaling that indicates: a first pre-coding matrix indicator (PMI) that indicates a first pre-coder for a first sub-band; and a second PMI that indicates a second pre-coder for a second sub-band. The first and second pre-coders may be included in predetermined candidate pre-coders. The UE may encode a physical uplink shared channel (PUSCH) block for transmission. The UE may scale the PUSCH block in the first sub-band by the first pre-coder. The UE may scale the PUSCH block in the second sub-band by the second pre-coder.

Abstract: Techniques for transmitting and receiving beamformed transmission(s) of a common search space of a DL (Downlink) control channel are discussed. One example embodiment that can be employed at a UE (User Equipment) comprises processing circuitry configured to: select a set of receive beamforming weights for a DL (Downlink) control channel; and decode one or more control channel sets from a common search space of the DL control channel, wherein each control channel set of the one or more control channel sets is mapped to an associated symbol of one or more symbols of a slot, wherein each control channel set of the one or more control channel sets has an associated transmit beamforming, and wherein each control channel set of the one or more control channel sets comprises a common set of control information.

Abstract: Embodiments of a station (STA) and method for communication in accordance with phase noise compensation are generally described herein. The STA may determine, based at least partly on one or more operational parameters, whether to perform phase noise compensation of data symbols of a received protocol data unit (PDU). For instance, the STA may compare the operational parameters with one or more thresholds. The STA may further determine a method of phase noise compensation based at least partly on one or more operational parameters. As an example, the STA may determine a type of interpolation to be used for an interpolation of phase noise estimates of pilot symbols to determine phase noise estimates of data symbols. Example operational parameters may include a signal quality metric, a carrier frequency offset (CFO) measurement and/or modulation and coding scheme (MCS).

Abstract: This disclosure relates to methods for transmission preemption in a wireless local area network. A downlink transmission may be performed by an access point device on a first wireless link. Signaling requesting or indicating preemption of the downlink transmission may be provided from a non-access point device to the access point device on a second wireless link. The downlink transmission may be preempted based at least in part on the signaling requesting or indicating preemption of the downlink transmission.

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.
