摘要
Techniques are described to perform cross-carrier scheduling. A wireless communication method comprises transmitting, by a network node to a communication node, a control information that schedules at least two shared channels for data transmission, where the control information is transmitted using a first channel associated with a first component carrier, and where the at least two shared channels are associated with at least two component carriers; and transmitting, to the communication node and using the at least two shared channels, at least two transmission blocks comprising data.

This application claims priority to International Application No. PCT/CN2020/120752, filed on Oct. 14, 2020, the disclosure of which is hereby incorporated by reference herein in its entirety.
This disclosure is directed generally to digital wireless communications.
Mobile telecommunication technologies are moving the world toward an increasingly connected and networked society. In comparison with the existing wireless networks, next generation systems and wireless communication techniques will need to support a much wider range of use-case characteristics and provide a more complex and sophisticated range of access requirements and flexibilities.
Long-Term Evolution (LTE) is a standard for wireless communication for mobile devices and data terminals developed by 3rd Generation Partnership Project (3GPP). LTE Advanced (LTE-A) is a wireless communication standard that enhances the LTE standard. The 5th generation of wireless system, known as 5G, advances the LTE and LTE-A wireless standards and is committed to supporting higher data-rates, large number of connections, ultra-low latency, high reliability and other emerging business needs.
