Abstract: The present invention relates to a wireless communication system. More particularly, a method and a device for restricted access window-based channel access in a WLAN system are disclosed. The method whereby a station (STA) performs channel access in a wireless communication system according to one embodiment of the present invention may comprise the steps of: receiving restricted access window (RAW) cross-border transmission allowance (CBTA) information from an access point (AP) in case an RAW is allocated to the STA; and performing transmission by the STA on the basis of the RAW CBTA information. In case the RAW CBTA information is configured as a first value, transmission by the STA beyond the border of the RAW may be allowed.

Abstract: Embodiments of a user station (STA) and methods for synchronizing with devices in a wireless communication network are generally described herein. In some embodiments, a STA accesses a list of social channels. The STA may transmit a scan message on a primary social channel. The primary social channel may be included in the list of social channels. The STA may determine an identity of the primary social channel by inspecting the list of social channels. The STA may synchronize with a device on the primary social channel when the STA detects transmissions on the primary social channel within a time duration subsequent to transmitting the scan message on the primary social channel. Otherwise, the STA may transmit a scan message on a secondary social channel selected from the list.

Abstract: With respect to a routing and a gateway (protocol conversion) in a network system, frame data can simply be generated even if a source node does not understand format specifications of all protocols, communication efficiency degradation caused by an enlargement of header information can be prevented as much as possible, and dealing with a new protocol can be simplified. A source node (data transmission device) transmits “common routing information”, which includes route information identifying all the nodes through which a message frame is routed from an own node to a destination node, while adding the common routing information on the message frame. Each relay node (data relay device) sequentially transfers the message frame while referring to the common routing information to perform identification of a destination, generation of a header, and update of the common routing information.

Abstract: Service function chaining is a sequence of service function instances that traffic flows need to traverse through in order. Those service function instances are not required to reside on the direct path and traffic flow, but steered through network nodes. Service function instances and network nodes process the packets that carry a service function chain (SFC) header. The packets are encapsulated by a virtual network overlay header and forwarded through the service function instances in an SFC. The SFC header in specific format will prompt the network nodes to re-route the packets in the traffic flow using destination based forwarding or path based forwarding method in the packet network as well as an SDN controller and/or in-band control plane, and able to carry the metadata with the packets.
