<p>The invention relates to a method of constructing data units in a mobile communication uplink system supporting multi-connectivity, the method including: receiving configuration information of multiple radio bearers from multiple different types of cells, wherein the configuration information indirectly includes correspondence relationship information of the multiple different types of cells with the multiple radio bearers; receiving scheduling grants from the multiple different types of cells; setting for each of the multiple different types of cells a rule of constructing an MAC data unit for the each of the multiple different types of cells at least based upon the configuration information, the scheduling grant and/or a priority procedure of logical channels to which multiple radio bearers corresponding to the cell are mapped; filling data corresponding to the multiple radio carriers corresponding to the each of the multiple different types of cells from the different logical channels, to which the multiple radio bearers are mapped, into corresponding MAC data units according to the rule; and transmitting the data units to the corresponding multiple different types of cells. The invention further relates to a corresponding product for performing the method.</p> |
