20140269575 | METHOD, BASE STATION, AND USER EQUIPMENT FOR IMPLEMENTING CARRIER AGGREGATION - Embodiments of the present invention provide a method, a base station, and a user equipment for implementing carrier aggregation. The method includes: determining, by a primary base station, to add a cell for a user equipment UE; and sending, by the primary base station, a first message to the UE, where the first message is used to instruct the UE to add the cell, the first message includes configuration information of the cell and an identifier or index of a base station to which the cell belongs, and the base station to which the cell belongs is a secondary base station. In the embodiments of the present invention, under the control of the primary base station of the UE, a cell of another base station can be added for the UE, so as to implement carrier aggregation between base stations, thereby further increasing user throughput of the UE. | 09-18-2014 |
20140308956 | METHOD AND DEVICE FOR DETERMINING TIMING ADVANCE GROUP OF SERVING CELL - The present invention provides a method for determining a timing advance group of a serving cell, including: determining, by a source base station of a user equipment, a target base station that the user equipment is to be handed over to; sending auxiliary information for determining a timing advance group of a target serving cell of the user equipment to the target base station; receiving the timing advance group of the target serving cell of the user equipment that is determined by the target base station according to the auxiliary information; and sending the timing advance group to the user equipment. Implementation of the method provided by the present invention can avoid timing advance grouping performed on a secondary carrier after handover, and reduce data transmission interruption or delay incurred by the handover, thereby improving quality of service of a communications service. | 10-16-2014 |
