Abstract: The present invention relates to a method for establishing or resuming a wireless communication connection in a wireless communication network. According to the method, a first message is transmitted from a first device to a second device. The first message includes a request for the second device to provide a data link layer communication forwarding between the first device and a base station. Furthermore, a connection between the first device and the base station is established or resumed via the data link layer communication forwarding of the second device.

Abstract: A wireless communication device (10) controls changing of a connection of the wireless communication device (10) to an access node (100) of the wire-less communication network between: a relay based connection to the access node (100), and either a direct connection to the access node (100) or another relay based connection to the access node (100). The relay based connection extends via a device-to-device communication link (30) between the wireless communication device (10) and a first further wireless communication device (40). The other relay based connection extends via another device-to-device communication link (30′) between the wireless communication device (10) and a second further wireless communication device (40′). Further, the wireless communication (10) sends an indication to the access node (100). The indication enables the access node (100) to identify an existing Packet Data Convergence Protocolcontext, which was utilized before changing the connection, and to continue utilizing the existing PDCP context after the changing of the connection.

Abstract: A user equipment (10) is operable in a first mode in which the user equipment (10) is configured for communication with a first cellular network (30) and a second mode in which the user equipment (10) is configured for communication with a second cellular network (40). Mode switching between the modes is performed autonomously by the user equipment (10) or under the control of a cellular network node. The user equipment (10) has a first power consumption when operating in the first mode and a second power consumption when operating in the second mode, the second power consumption being different from the first power consumption.

Abstract: An infrastructure equipment that transmits a radio network identifier to a communications device for identifying the communications device when allocating communications resources of the wireless access interface for transmitting downlink data to the communications device. After the communications device has entered an inactive connected state, the infrastructure equipment transmits control signals including the radio network identifier for allocating communications resources of the wireless access interface for the communications device to receive downlink data, determine whether the communications device is still within a radio coverage area of the infrastructure equipment, and if the communications device has left the coverage area, transmit an indication to the one or more other infrastructure equipment via the inter-connecting interface to trigger a process for transmitting downlink data to the communications device from the one or more other infrastructure equipment.

Abstract: A wireless telecommunications system including a terminal device; first infrastructure equipment operable to communicate with the terminal device using a first radio access technology (RAT) and second infrastructure equipment operable to communicate with the terminal device using a second RAT. During a handover procedure for handover from the first infrastructure equipment as a source master infrastructure equipment to a third infrastructure equipment as a target master infrastructure equipment, the second infrastructure equipment is operable to communicate with the third infrastructure equipment using an interface associated with the second RAT so as to allow information necessary for completing the handover to be exchanged between the first infrastructure equipment and the third infrastructure equipment via the second infrastructure equipment.

Abstract: A method of operating an access node of a radio access network of a cellular network includes participating in an early-data-transmission of a random access procedure of a UE. The method further includes, in response to said participating in the early-data-transmission: determining whether or not the UE requires an update information element of a notification area of the radio access network. The method further includes selectively transmitting the update information element if the UE requires the update information element.

Abstract: A plurality of payload messages is communicated on a radio link of a cellular network between a terminal and an access node of the cellular network. Each one of the plurality of payload messages includes a data packet encoded according to a given redundancy version. The number of the plurality of payload messages may be dynamically and flexibly adjusted in some embodiments. Examples are given which may be applied for coverage enhancement in the Internet of Things or Machine Type Communication domain.

Abstract: Determining whether service via a core network of the first type is available from the second cell. The method further comprises establishing a connection via the second cell by transmitting a message including a first indication, the first indication based on at least a portion of the identifier, and when service via a core network of the first type is not available from the second cell, transmitting in the message a second indication, the second indication indicating that the identifier was received from a core network different from the second type, without identifying the first type of core network.
