The single DCI schedules multiple transmission resources in at least two CCs. All CCs are regarded as a single CC and operate together by a single DCI. According to the method of embodiment 7, the benchmark CC has been determined. The method to determine the parameters configuration for each CC includes at least one of the following.

Method 1

The configuration parameters are determined based on one of the CCs (for example, the benchmark CC). For example, there are 2 CCs in the CC group, and the benchmark CC is CC0. The time domain resource allocation (TDRA) table is different between CC0 and CC1. Then the TDRA table is configured based on the CC0. Similarly, multiple-input multiple-output related parameters (demodulation reference signal, transmission configuration indication, physical resource block bundling and channel state information reference signal) and PDSCH data related parameters (frequency domain resource allocation (FDRA), scrambling ID, resource block group (RBG), modulation and coding scheme table, max code word, rate match, code block group, HARQ, physical uplink control channel cell and max layer) can be determined based on the benchmark CC.

Method 2

The FDRA parameters are determined based on the cascaded bandwidth part (BWP) in all CCs. For example, the FDRA field is configured by RRC signaling according to the cascaded BWP in all CCs. Firstly, Cascade the BWP of multiple CCs to form a large-size BWP. Then, the RBGs are divided in accordance with the relationship between the BWP and RBG granularities predefined in the protocol. If an RBG is across at least two CCs, the RBG is split in accordance with the CC of the RB. The number of split RBGs equals to the number of CCs that the RBG crosses. The allocation type can be configured by RRC signaling according to the cascaded BWP too.
