    Abstract: When performing data transmission with a first station in a bandwidth power saving mode by using an operating channel of the first station, an access point performs data transmission with a second station by using an operating channel of the second station. Therefore, even if the operating channel of the first station includes a primary channel, the access point can still perform data transmission with the second station by using another channel. Further, for the access point, although the operating channel of the first station occupies only a part of available bandwidth resources of the access point, the access point can still perform data transmission with the second station by using a remaining channel.

    Abstract: A communication method and apparatus are provided, to support data transmission over a multi-access session through multiple 3GPP paths or multiple non-3GPP paths. Access technologies corresponding to a first transmission path and a second transmission path in the multi-access session are of a same access type. A session management device sends, to a mobility management device, tunnel information and access technology information that correspond to the transmission paths, where the access technology is used to determine an access network device. The mobility management device determines the access network device based on the access technology information, and sends the tunnel information to the access network device. In this application, the session management device sends, to the mobility management device, the access technology information which is a finer granularity than an access type, and the mobility management device can accurately identify a corresponding access network device based on the access technology information.

    Abstract: A method for delivering data to User Equipments (UEs) is implemented in a node of a Radio Access Network (RAN), and includes receiving, from a network node, a packet including data that is to be delivered from a Core Network (CN) to one or more User Equipments (UEs); transmitting the packet to at least some of the one or more UEs via a broadcast transmission when the packet is received via a common downlink tunnel or via a first DL tunnel of a plurality of DL tunnels; and transmitting the packet to a particular UE of the one or more UEs via a unicast transmission when the packet is not received via the common downlink tunnel or is received via a second DL tunnel of the plurality of DL tunnels.

    Abstract: The disclosure relates to a 4th generation (4G) communication system such as Long Term Evolution (LTE), and a 5th generation (5G) or pre-5G communication system for supporting higher data transmission rates than 4G communication systems. A method performed by a session management function (SMF) device in a wireless communication system is provided. The method includes receiving, by the SMF device, a protocol data unit (PDU) session establishment request message from an access and mobility management function (AMF), transmitting, by the SMF device, a PDU session establishment response message to the AMF, transmitting, by the SMF device, a first session establishment request message to a user plane function (UPF) anchor, receiving, by the SMF device, a first session setup establishment message from the UPF anchor, transmitting, by the SMF device, a second session establishment request message to a radio access gateway (RAG), and receiving, by the SMF device, a second session establishment response message from the RAG, wherein the RAG includes a central unit (CU)-user plane (UP) and a UPF edge.

    Abstract: Disclosed is a method of transmitting/receiving a signal in a Mobile Management Entity (MME) of a mobile communication system, the method comprising: transmitting a subscriber information request message including information of a UE, to a Home Subscriber Server (HSS); receiving, from the HSS, a response message which corresponds to the request message and includes an indicator indicating whether it is possible to perform traffic offloading using a Wireless Local Area Network (WLAN) with regard to an Access Point Name (APN) connection or a Packet Data Network (PDN) connection of the UE; determining whether it is possible to perform the traffic offloading using the WLAN, on the basis of at least one of information included in the received response message and information configured in the MME; and; and transmitting, to the UE, a message including information on whether it is possible to perform the traffic offloading using the WLAN. A communication method according to an embodiment of the present specification can generate one or more PDN connections with regard to one APN when the UE accesses a PDN through the WLAN. Further, the communication method according to the present invention can effectively be subjected to a traffic offloading control by the eNB even when the UE is roaming.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to operate in a control mode. In some cases, the control mode may be an in active mode (e.g., a radio resource control (RRC) inactive mode). The UE may be configured to receive a control message from a network node. In some cases, the control message may include an uplink grant associated with a duration. The duration may relate to a timer, such as an expiration timer, for example. The UE may transmit an uplink transmission to the network node while operating in the control mode. The uplink transmission may be in accordance with the uplink grant and the duration. In some cases, prior to transmitting the uplink transmission, the UE may multiplex the uplink transmission with a second control message including an indication for the UE to remain in the control mode.
