COMMON SEARCH SPACE (CSS) FOR PAGING OF NB-IOT DEVICES

摘要

A method (100), performed by a user equipment (UE) (310) in idle mode, for determining common search space (CSS) for NB-IoT paging is disclosed. The method further comprises monitoring (104) a starting subframe of paging CSS for a Radio Network Temporary Identifier (RNTI). The starting subframe of paging CSS is determined as follows: a first subframe (SF0) (108), defined by a predetermined Paging Occasion subframe pattern, is used when SF0 is determined (106) to be a valid downlink subframe. A next valid downlink subframe after SF0 (110) is used when SF0 is determined (106) to be an invalid downlink subframe.
