Title
(EN) Uplink control information transmission method and apparatus under carrier aggregation
(ZH) 载波聚合下的上行控制信息传输方法及装置
Abstract
(EN)
The embodiment of the invention provides an uplink control information transmission method and apparatus under carrier aggregation. By sending first indication information to user equipment UE througha base station to indicate the UE to dynamically determine uplink control information UCI according to the first indication information, and allocating a PUCCH resource to the UE through the base station to transmit the UCI, the feedback of the UCI in a carrier aggregation scene can be achieved, and the performance of transmitting effective UCI is improved.
