The application relates to ultra-low latency data transmission in Wireless Local Area Networks (WLANs). An apparatus used in a non-Access Point Station (non-AP STA), includes processor circuitry configured to cause the non-AP STA to, when there is urgent data that must be transmitted in uplink without waiting for a scheduled slot: generate a Protocol Data Unit (PDU) from the urgent data; and transmit the PDU on a resource unit pre-assigned for urgent transmission, wherein the resource unit is multiplexed for uplink transmission from multiple non-AP STAs.

Ultra-low latency data transmission in WLANs

The present disclosure provides connection management techniques based on graph neural networks (GNN) and deep reinforcement learning (DRL) to optimize user association and load balancing. A graph structure of a communication network is considered for the GNN architecture and DRL is used to learn parameters of the GNN algorithm/model. Connection management is defined as a combinatorial graph optimization problem, and the DRL mechanism uses the underlying graph to learn weights of the GNN for an optimal user connections or associations. The connection management techniques can consider local network features to make better decisions to balance network traffic load while network throughput is also maximized. Implementations are provided based on edge computing frameworks include the Open RAN (O-RAN) architecture. Other embodiments may be described and/or claimed.

Graph neural network and reinforcement learning techniques for connection management

The present disclosure is related to multi-access traffic management in multi-access computing environments. A reliability enhancement engine (REE) operated by a multi-access multipath traffic manager identifies traffic flows that have high reliability requirements ('reliability flows') and performs admission control for the reliability flows. The REE determines a coding rate (e.g., a redundancy factor) and traffic distribution strategies for the identified reliability flows. The REE applies cross-access network coding (NC) on the reliability flows, and handles multi-access acknowledgements and traffic pacing, which may involve multiplexing traffic of the reliability flows with non-high-reliability traffic. Other embodiments may be described and/or claimed.
