Title
(EN) SIGNALING OF SYSTEM INFORMATION TO MTC-DEVICES
(FR) SIGNALISATION D'INFORMATIONS DE SYSTEME A DES DISPOSITIFS MTC
Abstract
(EN)
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).
(FR)
L'invention concerne un nœud de réseau et un équipement utilisateur (UE), et des procédés pour signaler des informations de système, SI, à des UE. Le procédé dans le nœud de réseau consiste à transmettre des SI à un ou plusieurs UE, les SI comprenant de multiples ensembles alternatifs, chaque ensemble affectant des valeurs différentes à un ou plusieurs paramètres de système radio. Le procédé consiste en outre à déterminer quel ensemble, parmi les multiples ensembles alternatifs, devrait actuellement être appliqué pour un UE, et à émettre un signal de sélection de SI à l'UE, le signal de sélection de SI indiquant l'ensemble déterminé, permettant ainsi à l'UE d'appliquer actuellement des paramètres de système radio appropriés également dans des conditions radio défavorables. L'UE peut être un dispositif de communication du type machine (MTC).
