FIG. 5G shows an exemplary flowchart of a wireless communication method 500G. Operation 502G includes 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 that are configured to operate as a single component carrier. Operation 504G includes transmitting, to the communication node and using the two shared channels, at least two transmission blocks comprising data.

In some embodiments of method 500G, the at least two component carriers includes a component carrier having a lowest frequency band or a highest frequency band, where the component carrier is a benchmark component carrier. In some embodiments of method 500G, the at least two component carriers includes a component carrier that is a benchmark component carrier, the at least two component carriers include one or more non-benchmark component carriers other than the benchmark component carriers, and a first set of configuration parameters for the one or more non-benchmark component carries are based on a second set of configuration parameters of the benchmark component carriers. In some embodiments of method 500G, the at least two component carriers includes a component carrier that is a benchmark component carrier, the at least two component carriers include one or more non-benchmark component carriers other than the benchmark component carriers, and a frequency domain resource allocation (FDRA) parameters for the data transmission are based on cascaded bandwidth part (BWP) of all of the at least two component carriers.
