Abstract: A user equipment for a wireless communication is configured to interact the radio link monitoring and beam failure recovery for resolving radio link failure quickly. When the out-of-synchronization (OOS) condition is detected in PHY sublayer, a timer may start to wait to receive a beam recovery success indication. Once the beam recovery success indication is received in RRC sublayer, the RRC sublayer may determine to consecutively receive a number of in-synchronization (IS) indications. If the number of the consecutively received IS indication is larger than or equal to a threshold number by comparing, the radio link is identified as being recovered.

When both devices have EDMG capability and the size of the datagram exceeds the maximum size defined by the wireless local area network transmission protocol, the datagram is segmented into a plurality of transmission data units on the MAC layer.

Abstract: In a wireless communication network, a Transmission Control Protocol (TCP) optimization engine receives user data. The TCP optimization engine transfers a TCP packet having the user data to wireless User Equipment (UE). The UE wirelessly receives the TCP packet using a wireless communication protocol and loads the TCP packet into a TCP buffer. The UE generates a TCP Acknowledgment (ACK) for the TCP packet that also indicates the wireless communication protocol. The UE wirelessly transfers the TCP ACK to the TCP optimization engine. The TCP optimization engine selects a new size for the TCP buffer based on the wireless communication protocol in the TCP ACK from the UE. The TCP optimization engine generates and transfers a TCP buffer instruction to the UE indicating the buffer size. The UE wirelessly receives the TCP buffer instruction and sizes the TCP buffer to the TCP buffer size.

Abstract: In order to provide flexible scaling and dynamic reconfiguration, a wireless local area network controller includes a virtual dataplane with one or more virtual machines. These virtual machines pre-calculate processing parameters for packets in a data flow. For example, the pre-calculated processing parameters may include: encapsulation parameters, quality-of-service parameters and priority parameters. Subsequently, when one of the virtual machines receives a packet in the data flow on an input port, the virtual machine modifies information in a header of the packet based on one or more of the pre-calculated processing parameters and information associated with the data flow (which specifies the one or more pre-calculated processing parameters). Then, the virtual machine transmits the packet on an output port. In this way, the virtual machine maintains a fixed inter-packet time between packets in the data flow.
