The present disclosure provides a method for forwarding to a Transport Control Protocol (TCP) receiver a TCP transmission sent from a TCP sender. The method includes: determining Time Division Duplex (TDD) reconfiguration time required for a TDD reconfiguration; comparing the TDD reconfiguration time with a predetermined threshold; suspending the forwarding of the TCP transmission to the TCP receiver during the TDD reconfiguration time if the TDD reconfiguration time is larger than the predetermined threshold; and resuming the suspended forwarding of the TCP transmission after the TDD reconfiguration time has lapsed. The present disclosure also provides a method for transmitting a TCP transmission to a TCP receiver, a base station and a user equipment.

Methods, apparatus, and systems that can be implemented to associate User Datagram Protocol (UDP) based connection identifiers with appropriate Quality of Service (QoS) flows are disclosed to enable Access Traffic Steering, Switching and Splitting functionality at lower layers and to allow accurate measurements of Round-Trip Time for all traffic on a session. In one example aspect, a wireless communication method includes determining, by one or more nodes in a core network for a session that comprises at least one QoS flow, at least two identifiers identifying two connections associated with the at least one QoS flow. The two connections are established according to a UDP based protocol. The method also includes establishing, by the one or more nodes in the core network, a mapping between the at least two connection identifiers and the at least one QoS flow.

A communication device includes, a controller that executes control to receive a data transmission packet from another communication device, create a reception confirmation packet indicating reception of the data transmission packet, and store the created reception confirmation packet in a transmission buffer, and a transmitter that transmits a part of reception confirmation packets stored in the transmission buffer to the other communication device but does not transmit reception confirmation packets other than the transmitted reception confirmation packet to the other communication device.

A host device establishes a wireless communication link with a client device, and implements a wired communication standard on the link to transfer a first data stream. To increase data throughput while complying with the standard, the host device replaces synchronizing information in a packet to be sent during a first synchronizing frame with configuration information indicating that packet exchange data of a second data stream is to be sent or received during a second synchronizing frame. The host device sends or receives the packet exchange data of the second data stream to or from the client device during the second synchronizing frame via the wireless communication link. The host device may send or receive the packet exchange data of the second data stream during delays or idle periods between sending and/or receiving packets of the first data stream via the wireless communication link according to the wired communication standard.

A window regulator for improving the performance of communications networks is described. In a communications network, data is sent downstream from a sender to a receiver, and acknowledgements are sent back upstream. When data is received at the receiver, the data is placed in a buffer and an acknowledgement of receipt may be sent. If no acknowledgement is received by a sender after a certain period of time, the sender retransmits the data. The receiver communicates how much data the receiver is willing to receive at any given time by sending an advertised window to the sender. The window regulator sets the size of the advertised window based on measurements of capacity in the network to improve the amount and rate of data sent downstream while avoiding loss of data and subsequent retransmissions.

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.

The invention relates to a method for enabling relocation of a function for processing data packets of a flow associated with a device. The method is performed in an arrangement of a communication system, which is allocated as a proxy for control messages exchanged between an instance of the function for processing the data packets of the flow and a control instance controlling how the function processes the data packets of the flow. The method comprises obtaining (920) information indicating that the function for processing the data packets is relocated from a first instance to a second instance. The method further comprises forwarding (930) control messages received from the control instance to the second instance of the function for processing the data packets and vice versa, in response to the obtained information.

Techniques for managing access combinations for multiple access protocol data unit (PDU) sessions are described. A communication device may receive control signaling indicating a configuration for a multiple access PDU session associated with a plurality of access links. The plurality of access links may be associated with a first type of access, a second type of access, or a combination thereof. The communication device may select a mode for allocation of a data flow associated with the multiple access PDU session to the plurality of access links based at least in part on the received control signaling. The communication device may allocate the data flow associated with the multiple access PDU session to the plurality of access links based at least in part on the selected mode, and transmit the allocated data flow over the plurality of access links associated with the two types of access.

This communication device performs data communication with another communication device via a wireless base station, and is provided with: a wireless information collection means for collecting wireless information relating to wireless communication of the other communication device; a congestion degree assessment means for assessing a congestion degree of a wireless link from the collected wireless information; and a schedule determination means for determining the schedule of the data communication with the other communication device on the basis of the assessed congestion degree.

There are provided measures for enabling/realizing interface functionality for RAN-WLAN radio aggregation, i.e. radio level integration/aggregation between a cellular radio access network and a wireless area network. Such measures exemplarily comprise user-plane data forwarding from a cellular radio access network over a wireless local area network to a terminal, both the cellular radio access network and the wireless local area network providing radio level connectivity for the terminal, wherein in the user-plane data forwarding user-plane data packets according to a cellular data convergence protocol are transported, at least partly, using a reliable transport protocol over the wireless local area network to the terminal, providing feedback on performance of user-plane data packets transport using the reliable transport protocol, at least partly, from the wireless local area network to the cellular radio access network, and executing flow control on the basis of the performance feedback.
