Problems solved by technology

The problem with this method is that CC needs to be planned and activated in the unlicensed frequency band. If it is used in NR-U technology, the granularity of resource control is relatively coarse in terms of frequency and time, and it is impossible to realize the unlicensed frequency band resources. Flexible Configuration and Effective Utilization

Abstract

The present disclosure provides a method and device for transmitting information, a base station, and user equipment. The method includes: determining supplementary system control information that thetarget user equipment communicates in an unlicensed frequency band, wherein the supplementary system control information is used to notify the target user equipment of configuration information of the supplementary bandwidth segment SBWP allocated on the unlicensed frequency band; sending the supplementary system control information to the target user equipment by the primary bandwidth segment BWP, wherein the primary BWP is a bandwidth segment BWP allocated for the target user equipment by the base station in the licensed frequency band; scheduling the target user equipment for information transmission in the primary BWP and the SBWP. The present disclosure provides a method for transmitting information, which can flexibly schedule unlicensed frequency band resources in a licensed frequency band, and improve the configuration flexibility and effective utilization of unlicensed frequency band resources.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method and device for transmitting information, a base station, and user equipment. Background technique [0002] With the development of wireless communication technology, mobile communication networks are gradually evolving to 5G networks. Similar to the LTE-U (LTE on Unlicensed spectrum) or LAA (License Assisted Access) technology in the 4G LTE (Long Term Evoluttion, Long Term Evolution) system, the 5G NR (New Radio) network also involves how to effectively use non- The technology of wireless resources such as 2.4GHz frequency band and 5GHz frequency band is called NR Unlicense (NR-U) technology, that is, the means of using 5G NR technology on the unlicensed frequency band (Unlicensed Spectrum). [0003] Since the unlicensed frequency band allows the use of various technologies such as Bluetooth and WiFi, the interference environment is usually comple...
