Abstract: front page image
(EN) The disclosure provides for control plane measurements in a wireless device. The wireless device may perform, on signals received over an unlicensed spectrum across multiple sub-frames, radio resource management (RRM) measurements of a cell. The wireless device may identify one or both of a first subset of the RRM measurements associated with a first subset of the sub-frames including opportunistic transmissions (i.e. before the transmission, clear channel assessment, CCA, is carried out) and a second subset of the RRM measurements associated with a second subset of the sub-frames including guaranteed transmissions (i.e. before the transmission, clear channel assessment, CCA, is not carried out). The wireless device may determine one or more RRM measurement values (e.g. RSSI, RSRQ) based on one or both of the first subset of the RRM measurements and the second subset of the RRM measurements. The wireless device may similarly perform radio link management (RLM) measurements and determine RLM measurement values based on the first and second subsets. The wireless device may also use timers (e.g. CCA timer, RLC timer) for uplink transmissions to detect radio link failures, RLFs.
(FR) La présente invention a trait à des mesures de plan de commande dans un dispositif sans fil. Le dispositif sans fil peut réaliser, sur des signaux reçus dans un spectre sans licence dans plusieurs sous-trames, des mesures de gestion des ressources radio (RRM) d'une cellule. Ledit dispositif sans fil peut identifier un premier sous-ensemble des mesures RRM associé à un premier sous-ensemble des sous-trames incluant des transmissions opportunistes, et/ou un second sous-ensemble des mesures RRM associé à un second sous-ensemble des sous-trames incluant des transmissions garanties. Le dispositif sans fil peut déterminer une ou plusieurs valeurs de mesures RRM sur la base du premier sous-ensemble des mesures RRM et/ou du second sous-ensemble des mesures RRM. Ce dispositif sans fil peut, de la même façon, réaliser des mesures de gestion de liaison radio (RLM) et déterminer des valeurs de mesures RLM sur la base des premier et second sous-ensembles. Ledit dispositif sans fil peut également utiliser des temporisateurs pour des transmissions en liaison montante afin de détecter des défaillances de liaison radio.
