Title
(EN) Method and device for transmitting uplink control information (UCI) in carrier aggregation
(ZH) 载波聚合下的上行控制信息传输方法及装置
Abstract
(EN)
Embodiments of the present invention provide a method and device for transmitting UCI in carrier aggregation, wherein a base station sends first instruction information to a user equipment (UE) to instruct the UE to dynamically determine UCI according to the first instruction information, and allocates to the UE a PUCCH resource for transmitting the UCI. The invention can be used for implementing feedback of UCI information in a carrier aggregation scenario, thereby improving the performance of transmitting valid UCI information.
