Moreover, the unlicensed carrier is shared. When multiple different systems are operating or when different operators of the same system are operating, some can be considered. Ways to share resources to improve carrier efficiency.

Due to the large number of wireless access technologies, there will be various wireless systems in the unlicensed carrier, which are difficult to coordinate with each other and have serious interference. Therefore, for LTE deployed in unlicensed carriers, there is still a need to support the regulation of unlicensed carriers. Most countries require the system to be unlicensed.
