A method and a device for receiving transmitting data in in a wireless local area network are provided. The device receives a physical layer protocol data unit (PPDU) from a station over a transmission bandwidth and determines whether the station is a member of a basic service set (BSS) managed by the device based on the PPDU. When the PPDU is a multi-user (MU)-PPDU, the AP determines that the station is not a member of the BSS managed by the AP. Such MU-PPDU includes a first signal field and a second signal field, the first signal field having bandwidth information indicating the transmission bandwidth, the second signal field having user-specific information with allocation for orthogonal frequency division multiple access (OFDMA) transmission.

Methods and apparatuses are provided through which a first node transmits, to a second node, a first message include a radio resource control (RRC) message associated with a terminal and an identifier allocated to the terminal to identify the terminal over an interface. The first node receives, from the second node, a second message including an identifier allocated to the terminal, an identifier of a data radio bearer, and uplink tunnel information. The first node transmits, to the second node, a third message including downlink tunnel information. The first node includes a radio link control (RLC) layer, a medium access control (MAC) layer, and a physical (PHY) layer. The second node includes an RRC layer and a packet data convergence protocol (PDCP) layer.

Application mobility is a unique feature of the edge computing to support relocation of application instance across edge computing hosts or between edge computing host and cloud computing over underlying mobile network. With the active-standby mode application instance implementation with support of L2 networks, the application mobility could achieve the service continuity with low latency switching time. An application mobility mechanism can be implemented in the data plane of edge computing host under the control of edge computing platform and management. It can be also implemented in L2 switching function of the User Plane Function in 5G networks.

In accordance with example embodiments as described herein there is at least an apparatus and method to perform determining that at least one packet data convergence protocol data unit of a packet data convergence protocol sublayer are duplicate packet data convergence protocol data units of the packet data convergence protocol sublayer having been submitted for transmission on two or more carriers in a communication network; signaling to a control sublayer an indication of each packet data convergence protocol data unit that is a duplicate packet data convergence protocol data unit; and based on the indication, preventing a trigger of a radio link failure when a number of retransmissions based on the duplicate packet data convergence protocol data units reaches a threshold number of retransmissions. Further, there is at least an apparatus and method to perform transmitting packet data convergence protocol data unit duplicates over two or more carriers; receiving an indication that indicates packet data convergence protocol data unit has been correctly transmitted via one of two or more carriers; and upon receiving the indication, instructing to discard other packet data convergence protocol duplicates over carriers other than the one of two or more carriers with a successful delivery.
