Abstract: According to one embodiment, a method for a wireless local area includes: generating a medium access control (MAC) protocol data unit (MPDU) to be transmitted to a target station; generating a physical layer convergence procedure (PLCP) protocol data unit (PPDU) by attaching a PLCP preamble to the MPDU; selecting a transmission channel; and transmitting the PPDU to the target station over the transmission channel. Selecting the transmission channel includes: performing clear channel assessment (CCA) on a first channel to determine whether the first channel is idle; and only after it is determined that the first channel is idle, selecting the first channel and at least one idle second channel as the transmission channel. The PLCP preamble includes channel allocation information indicating a bandwidth of the transmission channel.

Abstract: A method and apparatus for transmitting and receiving a frame supporting a short MAC header in a wireless LAN (WLAN) system are disclosed. A method for managing a sequence number in a wireless LAN (WLAN) system includes: transmitting, by a first station (STA), a frame including a short MAC header to a second STA. One of a receiver address (RA) field and a transmitter address (TA) field contained in the short MAC header includes an associated identifier (AID) value according to whether a transmission direction of the frame is an uplink (UL) or downlink (DL) direction, and if the RA field includes the AID value, the sequence number for the frame is assigned based on a station (STA) MAC address identified by the AID value.

Abstract: Techniques for providing closed-loop control and predictive analytics in packet-optical networks are described. For example, an integrated, centralized controller provides tightly-integrated, closed-loop control over switching and routing services and the underling optical transport system of a communication network. In one implementation, the controller includes an analytics engine that applies predictable analytics to real-time status information received from a monitoring subsystem distributed throughout the underlying optical transport system. Responsive to the status information, the analytics engine applies rules to adaptively and proactively identify current or predicted topology-changing events and, responsive to those events, maps reroutes packet flows through a routing/switching network and control and, based on any updated bandwidth requirements due to topology changes, dynamically adjusts allocation and utilization of the optical spectrum and wavelengths within the underlying optical transport system.

Abstract: Apparatus and methods are provided for LWA uplink routing. In one novel aspect, signaling of an address from the eNB to the UE to enable the UE to populate Address-3 of the MAC header to enable layer-2 forwarding of uplink LWA PDUs from the WLAN AP to an appropriate network entity that implements part or the whole WT functionalities. In one embodiment, the network entity is a WT node, or the eNB or a node aggregating multiple connections to a WT node. In one embodiment, the RRC signaling is used to send the WT node MAC address where the RRC signaling message is a PDCP-Config message or a WLAN-MobilityConfig message. In one embodiment, multiple WT nodes are connected with the WLAN AP. The eNB selects one WT node or the UE selects one WT node to populate the address-3 of the MAC header.

Abstract: A method, apparatus and computer program product are provided herein for enabling a D2D bearer to stay alive even in an instance in which a D2D connection is lost. In some example embodiments, a method is provided that comprises detecting a condition that indicates that a device-to-device bearer is to be terminated. The method of this embodiment may also include modifying a cellular bearer protocol data unit header, such that the cellular bearer protocol data unit header indicates that a cellular bearer service data unit is a device-to-device protocol data unit. The method of this embodiment may also include causing one or more device-to-device protocol data units to be encapsulated within one or more cellular bearer protocol data units, such that the one or more device-to-device protocol data units are transmitted via a cellular bearer.
