METHOD AND DEVICE FOR USING UNLICENSED FREQUENCY SPECTRUM

摘要

A method and device for using an unlicensed frequency spectrum are provided in the present invention. An access network device receives scheduling request information transmitted by User Equipment (UE); the access network device detects whether the unlicensed frequency spectrum is idle; the access network device begins to occupy the unlicensed frequency spectrum when detecting that the unlicensed frequency spectrum is idle; the access network device transmits an uplink scheduling signaling to the UE; the access network device stops occupying the unlicensed frequency spectrum after a preset period of time from the beginning of the uplink scheduling signaling transmission; and the access network device receives data packages transmitted by the UE in the unlicensed frequency spectrum. With an embodiment of the present invention, by the occupation of the unlicensed frequency spectrum in advance, a probability of the UE getting disturbed during an uplink transmission is effectively reduced, and the problems of errors, interruptions or delays and so forth of UE data transmission are solved.
