Abstract: A terminal device is operative to receive a broadcast message from a cellular network, the broadcast message including at least one bit associated with coverage enhancement, CE, operation of the terminal device. The terminal device is operative to control, when the terminal device is in CE operation, a radio interface to selectively delay, based on the at least one bit included in the broadcast message, a CE level dependent repetition of a random access preamble transmission.

Abstract: An access point node comprises a first interface configured to communicate with a radio access node of a cellular network via a radio link and further comprises a second interface configured to communicate with a terminal via a further radio link. The access point node is configured to establish an end-to-end connection with a user-plane gateway node of the cellular network in response to receiving an attach message from the terminal.

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 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: The present invention relates to a method for allocating radio resources in a wireless communication system (100). According to the method, at a base station (101), a first radio resource for a communication between the base station (101) and a relaying device (104) is determined. The relaying device (104) is configured to relay information between the base station (101) and at least one communication device (301) of the wireless communication system (100) located within a wireless communication range of the relaying device (104). Furthermore, a second radio resource for a communication between the relaying device (104) and the at least one communication device (301) is determined at the base station (101). A message (503) is transmitted from the base station (101) to the relaying device (104). The message (503) comprises information indicating the first radio resource and information indicating the second radio resource.

Abstract: The present invention relates to a method for determining a position of a terminal device (110) in a wireless communication system (100). According to the method, a first message (130-133) is broadcasted by the terminal device (110). The first message (130-133) comprises a positioning request and a terminal identifier identifying the terminal device (110). The first message (130-133) is received at a group of neighboring devices (120-123). Each neighboring device of the group of neighboring devices (120-123) is located within a wireless radio communication range of the terminal device (110). From one or more neighboring devices (120, 121) of the group of neighboring devices (120-123) a corresponding second message (140, 141) is transmitted to location server (103) of the wireless communication system (100). The second message (140, 141) comprises the terminal identifier and an indication that the terminal device (110) requested a positioning. For each neighboring device (120, 121) of the one or more neighboring devices a corresponding position information is determined. The position of the terminal device (110) is determined at the location server (103) based on the position of the one or more neighboring devices (120, 121).

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 signalling message including paging related information indicative of whether an user equipment (10, 19) is pageable or indicative of whether the UE (10, 19) will be paged is transmitted. The UE (10, 19) does not listen on a paging channel if the pageability information indicates that the UE (10, 19) is unpageable.

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.
