Abstract: Network node and UE, and methods therein for signaling system information, SI, to UEs. The method in the network node comprises transmitting SIto one or more UEs, where the SI comprisesmultiple alternative sets, where each set assigns different values to one or multiple radio system parameters. The method further comprises determining which set, out of the multiple alternative sets, that should currently be applied for a UE, and transmitting an SI selection signal to the UE, the SI selection signal indicating the determined set, thus enabling the UE to apply currently appropriate radio system parametersalso in unfavorable radio conditions.The UE may be an MTC device (Machine Type Communication).

Abstract: A method of decreasing radio link failure in challenging mobility scenarios for a user equipment, UE (600), device working in a cellular telecommunication network with a base station of each cell is disclosed. The method comprises measuring (100, 900) signal conditions for serving cell and neighbouring cells periodically; and estimating (106, 902) channel variations and comparing (108, 904) the estimate with a threshold value such that, when channel variations are determined to exceed a channel variations threshold, performing (112) an accelerated procedure comprising predicting whether handover is likely to occur in connection with the next scheduled measurement instant based on the signal measurements such that when handover is predicted, the procedure directly proceeds with sending (202. 312, 400, 910) an initial measurement report transmission request. Thereby handover delay can be reduced such that risk of radio link failure is reduced at significantly varying signal conditions. A UE device (600) and a computer program are also disclosed.

Abstract: Devices and methods for making a determination whether or not to handover a user equipment (UE) from a serving cell to a target cell are disclosed. The decision is based on a comparison that includes both control plane and data plane link quality considerations. The disclosed devices and methods may be applied to handover determinations in heterogeneous networks that implement a soft cell configuration.

Abstract: Se describen los sistemas y métodos relacionados con una señal de sincronización (18) particularmente muy adecuada para dispositivos inalámbricos (22) en un área de cobertura extendida (16) de una célula (14) de una red celular de comunicaciones (10). En una modalidad, una estación base (12) transmite una señal de sincronización (18) que incluye múltiples repeticiones de un bloque de sincronización básico durante un tiempo de coherencia de un canal de enlace descendente sobre el cual se transmite la señal de sincronización (18). Las múltiples repeticiones del bloque de sincronización básico durante el tiempo de coherencia hacen posible la combinación coherente durante la detección de la señal de sincronización (18) en los dispositivos inalámbricos (22) localizados en la red celular de comunicaciones (10) Esta combinación coherente hace posible, por ejemplo, que los dispositivos inalámbricos (22) localizados en un área de cobertura extendida (16) de una célula (14) servida por la estación base (12) se sincronice a una célula (14) utilizando una señal de sincronización más corta (18) que aquella que se requeriría si solo se utilizara combinación no coherente.

Abstract: Systems and methods related to reducing a cost of operation and/or manufacture of wireless devices under appropriate conditions are disclosed. In one embodiment, a wireless node in a cellular communication network determines a configuration for a wireless device. In one particular embodiment, the wireless device is a Machine-Type Communication (MTC) device. The configuration includes at least one of a retransmission configuration and an advanced receiver configuration. The wireless device is then configured according to the configuration. In this way, the operation of the wireless device can be more cost efficient, particularly in terms of radio resource and energy efficiency, based on the conditions in which the wireless device is operated.

Abstract: Embodiments herein relate to a method in a user equipment (10) for handling a radio link failure in a radio communications network. The user equipment (10) is served in a first cell (14) controlled by a radio base station (12) and which radio base station (12) is comprised in the radio communications network, The user equipment (10) detects a first indication of a failure of a radio link between the user equipment (10) and the radio base station (12). The user equipment (10) then transmits a second indication of radio link failure to the radio base station (12) when the first indication is detected.
