Abstract: A network device may detect a high traffic load for a wireless access network associated with the network device, and broadcast, to mobile terminals in the wireless access network associated with the network device, a signaling message indicating the high traffic load. The signaling message causes a mobile terminal to selectively limit wireless network access requests to the network device.

Abstract: A user equipment transmits at least one repeater information request (42, 52) to at least one terminal device to request information on a repeater capability of the at least one terminal device. The user equipment receives at least one repeater information response (43, 53) from the at least one terminal device. The user equipment selects a terminal device based on the received at least one repeater information response (43, 53). The user equipment transmits a repeater transition request (45) to the selected terminal device to request the selected terminal device to initiate activation of a repeater function.

Abstract: A cellular multiple-input and multiple-output, MIMO, system comprises a base station having a plurality of antennas. Pilot signals are received by the base station in each frame of a sequence of frames (60). The base station analyzes the pilot signals to determine radio channel properties of radio channels between respectively each one of a plurality of terminals and the base station. The sequence of frames (60) comprises frames of a first frame type (61, 63, 64, 68) and frames of a second frame type (62, 69). Each frame of the second frame type (62, 69) have a greater number of time slots in which the base station receives the pilot signals than each frame of the first frame type (61, 63, 64, 68). The frames of the second frame type (62, 69) are included periodically in the sequence of frames (60).

Abstract: A user equipment (2, 4, 6) receives mobility information representing a time-dependent location change of a mobile cell (11, 21) of a cellular communication network. A cell of a plurality of cells (11, 21, 31) of cellular communication network is selected for the user equipment (2, 4, 6) to camp on. Selecting the cell comprises processing the mobility information to determine whether the user equipment (2, 4, 6) is to camp on the mobile cell (11, 21).

Abstract: In an infrastructure equipment forming part of a mobile communications network, a controller is configured in combination with a receiver and transmitter to receive from one or more communications devices a channel state report for each of one or more predefined candidate channels within a frequency range, each of the candidate channels representing a minimum unit of communications resource usable to receive data on a downlink. The controller is configured to select, from the one or more candidate carriers, one or more component carriers for use in transmitting signals to the communications devices within the second frequency range to form a downlink providing a secondary cell, based on the received channel state reports, and to transmit an indication identifying the selected one or more component carriers to the one or more communications devices for use in transmitting signals to the one or more communications devices via the frequency range.

Abstract: A terminal device for wireless communication comprises a wireless interface configured for communication with a radio access network of a cellular communication network. The terminal device is configured to transmit, via the wireless interface, a message to at least one other terminal. The message includes configuration information related to a relay function of the terminal device. The terminal device is configured to activate the relay function to start relaying communication between a requesting terminal of the at least one other terminal and the radio access network after transmission of the message.

Abstract: The present invention relates to a method for operating a terminal device configured to establish a data communication upon receiving a request for establishing the data communication from a base station of a telecommunication network. According to the method, a usage state of the terminal device is determined. The usage state indicates a current usage of at least one function or application of the terminal device. Depending on the determined usage state a data traffic inactivity signal is sent to the base station. The data traffic inactivity signal instructs the base station to avoid sending the request for establishing the data communication to the terminal device for a predetermined amount of time.

Abstract: A node (100) of a cellular network selects a first modulation scheme setting for a first radio link to a first device (10′). The first modulation scheme setting is selected from a set of modulation scheme settings, each identified by at least one corresponding index. On the basis of a mapping of each of the indices to a corresponding set of transmission parameters, the node (100) identifies a first set of link parameters mapped to the index corresponding to the selected first modulation scheme setting. The node (100) then configures the first radio link according to the identified first set of link parameters. Further, the node (100) selects a second modulation scheme setting for a second radio link to a second device (10).

Abstract: The invention is directed to reducing paging overhead in a network. An exemplary method comprises: determining whether a user equipment (UE) is substantially stationary, wherein the UE is located in a first network cell associated with a network; in response to determining the UE is substantially stationary, transmitting an indicator to the network; determining whether the UE moves from the first network cell to a second network cell; and in response to determining the UE moves from the first network cell to the second network cell, transmitting updated location information associated with the UE to the network.
