Abstract: 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.

Method and terminal of optimizing frequency spectrum resource using
Man Wang
- 03 Jul 2013
TL;DR: In this article, the authors proposed a method of optimizing frequency spectrum resource using, where a terminal periodically monitors performance of a frequency spectrum segment within an acceptable range of the terminal, and when authorized frequency spectrums of the terminals are all occupied, according to the currently-monitored performance of the spectrum segment, the terminal can confirm a switched target non-authorized frequency spectrum from non-authorized frequency spectrum of the frequency spectrum segments of the segment within the acceptable range, and is switched to the confirmed target non authorized frequency spectrum.
