The embodiment of the invention discloses system and equipment scheduling and preamble sending method, a non competitive random access, relates to the field of wireless communication, inter carrier for non competitive random access technology can not solve the existing problem of PDCCH dispatch. In the invention, the base station downlink non random access in the competition for scheduling terminal control indicator (DCI) add member identification information in the uplink carrier signaling; through physical downlink control channel (PDCCH) is sent to a terminal of the terminal to the DCI signaling, DCI signaling in the detection, in the upstream of the upstream member carrier carrier member the identifier corresponding to the network side transmits a preamble sequence (preamble). The present invention provides support for inter carrier non competitive random access of PDCCH scheduling.
