a method for indicating and determining a carrier scheduling mode in a long term evolution - advanced system is disclosed in the present invention . the method is that : a network device determines whether a component carrier adopts a cross - carrier scheduling mode to perform resource scheduling , and transmits first indication information that indicating whether the component carrier adopts the cross - carrier scheduling mode to perform the resource scheduling to a user equipment , so as to indicate the ue to determine whether adopting the cross - carrier scheduling mode to perform the resource scheduling on a component carrier supported by the ue itself according to the received first indication information . by adopting the present solution , the ue supporting multi - carriers in the lte - a system is able to determine which mode one certain component carrier or several certain component carriers adopt to perform the resource scheduling , thereby performing data reception / transmission correctly .
