| 摘要 |
A method and a device for connecting a UE, a base station, and multiple serving cells are disclosed in the present invention. Addressing the problem of the PUCCH power reduction that can be caused by PUCCH transmission on a secondary cell during dual-connectivity communication, the present invention provides a solution for PUCCH power reduction during dual-connectivity communication. In one embodiment, when power is reduced, the priority level of PUCCH transmission on a secondary cell is lower than the priority level of PUCCH transmission on a primary cell. The present invention can ensure PUCCH reception quality on a primary cell, guaranteeing the robustness of UE connectivity. Moreover, the present invention maintains the highest degree of compatibility with present systems. |
