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.

Embodiment 9

This embodiment describes one method for receiver to determine HARQ feedback according to scheduled transmission.

The transmission mode of the CCs scheduled by the single DCI include TB based transmission or CBG based transmission. All CCs are regarded as a single CC and operate together by a single DCI. The method to determine how to perform feedback includes at least one of the following.

Method 1

The scheduled transmission resource is within the BWP range of one CC, and the receiver execute fallback scheduling. The feedback is performed on the benchmark CC or the CC including the active BWP.

Method 2

The scheduled transmission resource is within the BWP range of more than one CC, and the receiver provides independent feedback on each CC.

Embodiment 10

This embodiment describes example methods for receiver to determine the re-transmission.

The transmission mode of the CCs scheduled by the single DCI include TB based transmission or CBG based transmission. All CCs are regarded as a single CC and operate together by a single DCI. The method to determine how to perform re-transmission includes at least one of the following.

Method 1

The re-transmission is performed on the benchmark CC or the CC including the active BWP. The benchmark CC is predefined by protocol or configured by RRC signaling. In one example, for the TB based transmission, the re-transmission can include the entire transmission block. In another example, for the CBG-based transmission, the re-transmission can include the CBG which is transmitted incorrectly for the first time.

Method 2
