Provided in the present invention are user equipment and a method thereof, and a base station and a method thereof. The method in user equipment comprises: comprises: receiving a switching MAC CE from a base station; and activating and/or deactivating an RLC entity and/or a logical channel associated with a bearer that supports the PDCP duplication based on the switching MAC CE.

Systems and methods are provided for managing connections between a wireless headset and various user devices, e.g., to answer or place a call at a particular user device (e.g., a device that is not currently connected to the headset) as a headset-supported call in which the call audio is routed from the particular user device to the headset and/or vice versa. Connections between the headset and relevant user devices may be controlled or facilitated by suitable software and hardware components to establish the headset-supported call. For example, such device connections may be controlled or facilitated by a cloud-based network including remote server(s). As another example, the device connections may be controlled or facilitated by a local mesh network, e.g., including user device(s) connected to the headset and the particular user device. As another example, the device connections may be cooperatively managed by a cloud-based network and a local mesh network.

Various embodiments disclose a computer-implemented method for managing multi-mode communications between node devices in a network comprising initiating a carrier sense multiple access with collision avoidance (CSMA/CA) session at a first node while in a first mode, where the CSMA/CA session is associated with a request to transmit a data message to a second node, switching from the first mode to a second mode, in response to switching to the second mode, suspending the CSMA/CA session at the first node, switching back to the first mode, and in response to switching back to the first mode, resuming the CSMA/CA session at the first node.

Techniques are provided for downlink packet replication to support handovers. In one example, downlink packet replication occurs on a fabric node in an S1AP handover scenario. In another example, downlink packet replication occurs on a source Access Point (AP) using a target AP as a secondary AP in an S1AP handover scenario. In yet another example, downlink packet replication occurs on a source AP using packet encapsulation in an S1AP handover scenario. In still another example, downlink packet replication occurs on a source AP in an X2 handover scenario. Similar techniques are provided for any suitable telecommunications/cellular technology.

A control plane of a network, including radios of a radio access network controlled by the control plane and user plane functions controlled by the control plane, establishes first and second protocol data unit (PDU) connections each to handle the same flows of traffic for ultra-reliable low latency communications (URLLC) from user equipment to a data network through first and second source radios, respectively. Due to mobility of the user equipment, the control plane relocates the flows from the first and second source radios to first and second target radios, respectively. To relocate the flows, the control plane receives from the first target radio a notification that identifies flows that cannot be activated on the first target radio. In response to the notification, the control plane commands the first target radio to prioritize the flows that cannot be activated above remaining ones of the flows.

There is provided a method in a device of a cellular network, the method comprising: receiving a user plane data from a source network node of the cellular network; detecting that at least one quality condition with respect to the user plane data transfer is met; and in response to the detecting that the at least one quality condition is met, causing a transmission of an indication for a data forwarding or duplication to a target network node of the cellular network or to the source network node, the data forwarding or duplication causing the source network node to forward or duplicate a user plane data of the device to the target network node.

Disclosed is a design and implementation of a Wi-Fi based network (e.g., roadside hotspot network designed to operate at vehicular speeds and picocell, meter-sized, cells). The disclosed access points (APs) make delivery decisions to the vehicular clients they serve at millisecond-level granularities, exploiting path diversity in roadside networks. In order to accomplish this, buffer management algorithms are employed that allow participating APs to manage each other's queues, rapidly quenching each other's transmissions and flushing each other's queues. An example embodiment of the disclosed approach employs an eight-AP network alongside a nearby road, and was evaluated with mobile clients moving at up to 25 mph. Depending on mobility speed, the disclosed approach achieves a 2.4-4.7 times TCP throughput improvement over a baseline fast handover protocol that captures the state of the art in Wi-Fi roaming, the IEEE 802.11k and 802.11r standards.

A wireless device includes a first mobile equipment and a second mobile equipment sharing a single subscriber identity module. The wireless device sends a first attach request as part of a first attach procedure to a cellular network using the first mobile equipment via a first base station to establish a first communication channel to the cellular network, and sends a second attach request as part of a second attach procedure to the cellular network using the second mobile equipment via a second base station to establish a second communication channel to the cellular network. The first and second attach procedures are performed using a same subscriber identity provided by the single subscriber identity module. Upon completion of the first and second attach procedures, data communicated between the wireless device and the cellular network is transferred redundantly over the first communication channel and the second communication channel.

There is provided a method, comprising: configuring, by a network node controlling a macro cell of a cellular communication system, at least one handover trigger related signalling configuration for at least one terminal device of the cellular communication system; receiving, by the network node controlling the macro cell, as a result of said signalling configuration, an uplink message broadcasted by the at least one terminal device via a local area access node; recognizing the local area access node as an edge node located at an edge of a coverage area of the macro cell; and initiating a handover of the terminal device between the macro cell and a neighbouring macro cell.

Provided are a path switching method and a terminal device. The terminal device has a packet data convergence protocol (PDCP) layer, the PDCP layer being able to send uplink data to a first cell group or a second cell group, the first cell group and the second cell group being different cell groups, the PDCP layer currently sending the uplink data to the first cell group; the method comprises: the terminal device enabling the switching of the PDCP layer from sending the uplink data to the first cell group, to sending the uplink data to the second cell group; and the terminal device sending first uplink data to the second cell group, the first uplink data at least including first data, the first data referring to the data that the terminal device has sent to a radio link control protocol (RLC) layer of the first cell group.
