If the UE is configured with cross-carrier scheduling, when two PDCCH candidates originating from a CSS and a USS, respectively, have cyclic redundancy check (CRC) scrambled by the same radio network temporary identifier (RNTI) and have a common payload size and the same first control channel element (CCE) index, the UE may interpret that only the PDCCH originating from the CSS is transmitted.EFFECT: high accuracy of detecting accuracy of detecting control information.15 cl, 8 dwg
