摘要

A method (100) performed by a user equipment (EU) (310) in idle mode for determining the common search space (css) for nb-iot radiosignalization is described. The method comprises determining (102) a set of periodic subframes as a radiosignal occasion subframe (po) pattern. The method further comprises monitoring (104) an initial subsystem of the biosignal css for a temporary radio network identifier (rnti). the initial radiosignalisation css subframe is determined as follows: a first subframe (sf0) (108), defined by the radiosignal occasion subframe pattern, is used when sf0 is determined (106) as a valid downlink subframe. a next valid downlink subframe after sf0 (110) is used when sf0 is determined (106) as an invalid downlink subframe.
