CROSS REFERENCE TO RELATED APPLICATIONS

The present application is the U.S. national phase of PCT Application No. PCT/CN2018/076645 filed on Feb. 13, 2018, which is incorporated herein by reference in its entirety for all purposes.

TECHNICAL FIELD

The subject disclosure relates to the field of communication, and more particularly, to a method and device for transmitting information, a base station, and User Equipment (UE).

BACKGROUND

With development of wireless communication technology, a mobile communication network is gradually evolving toward a 5th Generation (5G) network. Similar to License Assisted Access (LAA) or Long Term Evolution (LTE) on Unlicensed band (LTE-U) in a 4G LTE system, New Radio (NR) Unlicense (NR-U) in a 5G NR network further involves effective use of a wireless resource of an unlicensed band such as of 2.4 GHz, 5 GHz, etc., i.e., means for applying 5G NR over an unlicensed band.

As various technologies such as Bluetooth, Wireless Fidelity (Wi-Fi), etc., are allowed to be used in an unlicensed band, a complex interfering environment may generally be involved. Controlled use of an unlicensed band is generally recommended in order to prevent abuse. For example, use of an unlicensed band may be controlled by a licensed band. For example, LAA in LTE may be implemented by scheduling a Component Carrier (CC) in an unlicensed band. A problem with this plot is that a CC may have to be planned and activated in an unlicensed band. When applying the plot to NR-U, granularity of resource control in terms of frequency and time may be too coarse to achieve flexible configuration and effective use of a resource in an unlicensed band.
