An electronic device and method for using a rate adaptive codec for dynamic point cloud compression is provided. The electronic device receives a point cloud frame (PCF) sequence that includes a set of reference PCFs and a current PCF that is to be encoded. The electronic device generates 3D feature data based on application of a neural network-based encoder on at least one of the set of reference PCFs and the current PCF. The electronic device selects from an encoding pipeline, an encoding path as an I-frame encoding path or a P-frame encoding path for the current PCF. The selected encoding path extends from an output of the neural network-based encoder and includes a first sequence of transformation operations that is applicable on the 3D feature data. The electronic device generates a bit-stream of coded PCF based on application of the first sequence of transformation operations on the 3D feature data.

Parts-based blendshape generation involves establishing a 4D capture sequence. A face, hands and legs are able to be established for the meshes using a template to generate tracked and templated meshes. Specific muscle deformations are extracted. Pose-specific spatial deformations are integrated into a pose to generate specific flesh deformations. A muscle deformation method enables muscle part-based approach deformation (e.g., just biceps if flexing arms). The muscle deformation also enables generating a novel pose not captured.

An enhanced method of handling block Acks, such as for latency sensitive traffic streams, for which a separate block Ack mechanism is established, which is separate from other traffic in the same TID. With this separate block Ack mechanism the recipient STA can have an independent receive reordering buffer control for latency sensitive traffic, so that the MSDU or A-MSDU of latency sensitive traffic can be passed to the next MAC process in order of increasing sequence number of the MSDUs or A-MSDUs since those MSDUs and A-MSDUs have the same QoS requirement, such as the latency time. This mechanism reduces the chances of latency sensitive traffic being stuck in a receive reordering buffer behind other traffic in the TID and having its traffic expire.

Enhanced wireless protocols are described for stations (STAs) which are associated with Multiple-Link Devices (MLD). One embodiment describes overcoming replay attacks (with or without a modified Sequence Number (SN) even when protected by a Group Temporal Key (GTK) or similar. Other embodiments describe MLP operating enhancements associated with utilizing a Robust Security Network Element (RSNE), or NSTR Mobile AP MLD, or Target Beacon Transmission Time (TBTT) Information fields with Reduced Neighbor Reports (RNR), or Quiet Channel elements in an Association/Reassociation, or that use PPDU end alignment are all subject to specific shortcomings when applied to MLDs.

A wireless IEEE 802.11 queuing architecture supporting Low Latency Low Loss Scalable throughput (L4S) and Dual Queue Active Queue Management (AQM) in which queues for both L4S streams and classic streams are contained in the medium access control (MAC) layer, and one or more of these queues are configured with more than one internal queue, to which different L4S packets and other packet types are retained in different internal queues within the MAC transmit queues. The MAC queues are configured for MAC layer buffering of L4S packets and classical packets in separate queues and/or queues having internal queues for buffering different packet types, classifications, latency sensitivity, QoS considerations, and so forth. The architecture also allows for multiple packet queues in the upper layers above the MAC layer.

An enhanced protocol for addressing communication issues arising from using a Remote Radio Head (RRH). An Access Point (AP), denoted as Remote Radio Head (RRH) AP, consists of a Central Unit (CU) and at least one RRH that can be located remotely. The functionalities of the Medium Access Control (MAC) and the Physical (PHY) layers of the RRH AP are split between the CU and RRH; with the CU exchanging frames between the MAC layers, and the RRH transmitting and receiving the physical signals through the channel.

The single cell identification described herein utilizes cell image information and extracts cell features with a neural network model to subtly distinguish the noise events from single cells, allowing the user to choose which different types of noise events to exclude depending on the requirement of applications. The fast neural network model is able to extract more abundant and specific cell features than handpicked features, which enables the model to be equipped with higher accuracy and higher discriminative capability of distinguishing noise events and identifying the single cells in real-time. Utilization of a neural network model for real-time single cell identification represents a novel technique never applied before. It allows high discriminative capability and high accuracy compared to traditional FACS (Fluorescence-activated Cell Sorting). The usefulness of this technique is to integrate with any brightfield (BF) model and fluorescence (FL) model to identify single cells for different downstream applications.

Methods are described for overcoming contention issues during R-TWT SPs. In particular, enhanced mechanisms are defined in prioritizing transmissions of R-TWT TIDs during corresponding R-TWT SPs. In addition, enhanced access mechanisms are described for overcoming issues with stations accessing the channel after sensing an idle channel after a DIFS or AIFS time period.

Protocol enhancements for IEEE 802.11 handling of Buffer Status Reports (BSRs) to provide real-time information on Quality of Service (QoS) requirements. A non-AP STA can report QoS status about portions of a buffer, which then allows the AP to schedule transmissions for those buffers toward satisfying their QoS requirements. The non-AP STA can also change parameters of the QoS characteristics element of an existing SCS to allow the AP to schedule transmission for the SCS traffic with the new parameters immediately. The non-AP STA can also report on buffers that should soon arrive to allow the AP to trigger the transmission before those buffers arrive. Additional benefits are also provided.

A wireless communication apparatus, method or protocol for wireless STAs using CSMA/CA on a wireless local area network (WLAN). A receiver STA receives MSDUs or A-MSDUs which include an expiration time, from a transmitter STA. The receiver STA stores the MSDUs or A-MSDUs with expiration time in its receive reordering buffer of the corresponding high-throughput (HT)-immediate block acknowledgement (Ack) agreement. The receiver STA passes the MSDU or A-MSDU to a next MAC process before an expiration time of the MSDU or A-MSDU. Thus, the percentage of latency sensitive traffic packets being communicated prior to expiration is increased.
