A method for use in a IEEE 802.11 device, comprising: wirelessly connecting, by the device, to a gateway that is part of a wireless local area network (WLAN), the gateway configured to operate as an access point (AP) for the WLAN and bridge the WLAN to the Internet; receiving, by the device from the gateway, an announcement message including a network identifier (NI) of a subnetwork of the WLAN, the subnetwork including the gateway and a first node that is also configured to operate as an AP for the WLAN; transmitting, by the device to the gateway, a request message to join the subnetwork; receiving, by the device from the gateway, a response message including a confidential credential for connecting to the subnetwork; establishing a first connection to the first node based on the confidential credential and the NI and beginning to operate as an AP for the WLAN.

Methods and apparatus, including computer program products, are provided for packet forwarding control protocol (PFCP) message bundling. In an example embodiment, an apparatus comprises at least one processor and at least one memory including computer program code. In some embodiments, apparatus can be configured to: determine that more than one control protocol messages should be sent between a control plane entity and a user plane entity or said user plane entity and said control plane entity; determine the control plane entity and the user plane entity support sending and receiving a single datagram carrying more than one control protocol messages; extend a header of each control protocol message to indicate that the datagram is carrying more than one control protocol messages; combine one or more message types and respective message elements of the more than one control protocol messages into the single datagram; and cause sending said single datagram.

A method for retransmitting a packet on a wireless fidelity link includes receiving a packet retransmission request sent by a user terminal and determining a packet that needs to be retransmitted, detecting a downlink quality indicator on a gateway side of a first wireless fidelity link and a downlink quality indicator on a gateway side of a second wireless fidelity link, determining a link for retransmitting the packet, based on the downlink quality indicator on the gateway side of the first wireless fidelity link and the downlink quality indicator on the gateway side of the second wireless fidelity link, and sending, to the user terminal on the determined link for retransmitting the packet, the determined packet that needs to be retransmitted.

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for determining number of retransmissions of sidelink data in wireless communication system, the method comprising: determining number of retransmissions of sidelink data when the sidelink data is available for transmission; transmitting the sidelink data via direct interface between UEs; and retransmitting the sidelink data as many as the determined number of retransmissions.

Disclosed are methods and systems for the testing and optimization of one or more wireless devices, e.g., wireless cameras, such as in conjunction with corresponding systems. Wireless device test capabilities include any of: single device, wireless video rate/delay/interference test; multi-security camera system wireless DC power range tweet with and without noise/interference; security camera system image quality with and without movement in day and night mode; multi-camera wireless range vs. DC power tweet with and without interference; WLAN beacon/sniffer automation; wireless audio range testing; security camera uplink testing; and optical synchronized video/audio distribution (optical fiber).

The present disclosure relates to a pre-5th-generation (5G) or 5G communication system for supporting higher data rates beyond 4th-generation (4G) communication systems such as a long term evolution (LTE) system. The disclosure includes a first evolved node B (eNB) in a communication system supporting dual connectivity. The first eNB includes a controller configured to detect that a path between a second eNB and a terminal is blocked, and a transmitter configured to transmit, to the terminal, a first data unit of a plurality of data units to be transmitted through the path between the second eNB and the terminal.

A wireless communication system includes a first wireless communication device, and a second wireless communication device. The first wireless communication device includes: a communicator that delivers, to the second wireless communication device, data addressed to a third wireless communication device and receives, from the second wireless communication device, information on communication quality according to failed data of which delivery fails among the data delivered from the second wireless communication device to the third wireless communication device; and a controller that controls delivery of the data in accordance with the information on the communication quality.

Certain aspects of the present disclosure provide techniques for support response-based resource management. A UE may determine an uplink response to be transmitted in response to a downlink transmission by a first TRP participating in CoMP to the UE with a second TRP. The first UE may select which of the first TRP or the second TRP to transmit the uplink response to, based at least in part on the determined uplink response and may transmit the uplink response to the selected first or second TRP.

The present invention relates to a technology for a sensor network, machine to machine (M2M) communication, machine type communication (MTC), and the Internet of things (IoT). The present invention can be used for intelligent services (smart home, smart building, smart city, smart car or connected car, health care, digital education, retailing, security and safety related services, and the like) based on the technology. The present invention provides a method by which a node transmits a signal in a mesh network, the method comprising the steps of: transmitting a packet; receiving at least one packet transmitted from at least one peripheral node except for the node, after transmitting the packet; determining whether the at least one peripheral node has normally received the packet on the basis of the at least one packet; and retransmitting the packet if it is determined that it is necessary to retransmit the packet, on the basis of the determination result.
