Similarly, if public information if it exists in the configuration information of any group of cell, in order to save signaling overheads, the public information in the configuration information of this group of cell is carried in the public information field of the first configuration message.

402, terminal device receives the first configuration message that base station is sent.

After terminal device receives the first configuration message of base station transmission, the configuration information of cell in the first configuration message can be stored.

So, it can be in the covering very little of SCell, as terminal device is mobile, the quality of the SCell of terminal device quickly changes, when needing continually to configure/go configuration SCell, the application can carry the configuration informations of multiple cells by the first configuration message and be sent to terminal device, so that terminal device once stores the configuration information of multiple cells, can reduce the frequency for sending configuration message arrangement/go configuration cell.

403, base station sends the second configuration message to terminal device, second configuration message includes the index of N number of cell or the index of N group cell, N is the positive integer greater than 1, second configuration message is used to indicate terminal device at least one cell, and the configuration information of the corresponding cell of index of the index or N group cell of N number of cell is configured to the configuration information of the secondary cell of terminal device.
