A first network node, for supporting transport of data in a wireless communication network. One or more first data transmission connections, for first data flows, are established between the first network node and one or more service providing entities. One or more second data transmission connections, for second data flows associated with the first data flows, are established between the first network node and one or more wireless terminals via a target node. The first network node obtains a buffer measure that is indicative of a buffering degree at the target node for a first group of the second data flows. The first network node controls, based on the obtained buffer measure, a transmission pace between the first network node and the target node for a second group of the second data flows.

In some examples, a first wireless device communicates with a group device that wirelessly interconnects a plurality of wireless devices in a group, to obtain, from the group device, information identifying a second wireless device from which the first wireless device is able to use a wireless connectivity of the second wireless device to a wide area network (WAN), the second wireless device being part of the plurality of wireless devices. The first wireless device communicates data over the WAN using the wireless connectivity of the second wireless device.

[Solution] There is provided a communication control device including: a communication status grasping unit configured to grasp a communication status of wireless communication of image information between an image shooting device and a surgical site image information acquiring unit on the basis of an operating room image showing a situation of an operating room, the image shooting device capturing an image of a surgical site of a patient, the surgical site image information acquiring unit acquiring information on a surgical site image captured by the image shooting device for display control of the surgical site image; and a communication method deciding unit configured to decide a communication method between the image shooting device and the surgical site image information acquiring unit on the basis of the grasped communication status.

A method for communicating between a motor vehicle and an infrastructure. The method includes: ascertaining a requirement vector for at least one function to be carried out with the aid of the motor vehicle and/or the infrastructure, the requirement vector indicating which characteristics of a communication link between the motor vehicle and the infrastructure should simultaneously be satisfied for an execution of the function; ascertaining a communication state, which indicates which communication possibilities exist for a communication link between the motor vehicle and the infrastructure; ascertaining a radio channel between the motor vehicle and the infrastructure based on the requirement vector and based on the ascertained communication state; establishing a communication link between the motor vehicle and the infrastructure using the ascertained radio channel to carry out the at least one function using the established communication link.

A method of handling multipath connections in a Public Land Mobile Network (PLMN). The method comprising the steps of determining within the PLMN that a path, established across the PLMN, is a backup path of a multipath connection and providing an explicit indication to one or more nodes within the PLMN that the path is a backup path using a protocol layer that is otherwise unaware of the multipath connection. The method further comprises the step of, at the or each notified node, applying a handling to the path that is differentiated from the handling of non-backup paths.

The present disclosure relates to a method performed in a radio communications network which is configured to enable multipath communication. The method comprises providing an explicit indication that a path within a multipath connection is a backup path prior to establishment on or handover to a radio link of the backup path, transmission of the explicit indication to the base station, where it is interpreted. This allows an early indication that the path is a backup path and allows the base station to handle and prioritise use of radio network resources and/or connection characteristics for the radio link. The explicit indication may be in the radio level signalling or in handover signalling.

Methods and systems for managing a Multipath Transmission Control Protocol (MPTCP) in an electronic device during data transport between the electronic device (client device) and other electronic device (host device) are described. The method includes monitoring one or more factors associated with the MPTCP implemented in the client device. Further, based on the one or more factors that are monitored, the method includes determining whether to enable the MPTCP in the electronic device for a current data transport. Thereafter, the method includes determining a mode, among a plurality of modes provided for the MPTCP, to control a plurality of subflows of the MPTCP when the MPTCP is enabled for the current data transport. The method further includes dynamically switching the mode of the MPTCP during the current data transport based on the one or more factors being monitored during the current data transport.

Techniques are disclosed for avoiding reduction in throughput due to redundant transmission of downlink packets when a split bearer is deleted. A user equipment includes a transmission and reception unit to communicate with a master base station and a secondary base station simultaneously in dual connectivity; an RLC (Radio Link Control) layer processing unit configured to have an RLC layer for the master base station and an RLC layer for the secondary base station; and a PDCP (Packet Data Convergence Protocol) layer processing unit configured to have a PDCP layer transmitting and receiving data to/from the RLC layer for the master base station and the RLC layer for the secondary base station. When the split bearer configured for the secondary base station is deleted, the RLC layer processing unit performs re-establishment on the RLC layer for the secondary base station and releases the split bearer after execution of the re-establishment.

Systems and methods for improving data transmission rates in communication networks are disclosed. In an 802.11 wireless communication network, where a source node of the wireless network transmits TCP data to a destination node of the wireless network, the destination node does not transmit TCP acknowledgments (ACKs) for the TCP data if 802.11 ACKs indicate that the destination node received the TCP data. If a source outside the wireless network transmits TCP data to the destination node within the wireless network through an intermediate device, such as an access point, the destination node suppresses transmitting TCP ACKs. The intermediate device transmits TCP ACKs as proxy for the destination node to the source. The intermediate device also suppresses TCP ACKs where a source node within the wireless network sends the TCP data to a destination node outside of the wireless network.
