Uplink transmission method and device for carrier aggregation, and base station

An embodiment of the invention discloses an uplink transmission method and device for carrier aggregation, and a base station. In the uplink transmission method for carrier aggregation, uplink carriers comprise a main carrier and an auxiliary carrier, and the steps executed at a base station side are as follows: estimating the uplink channel quality of the auxiliary carrier to obtain the estimated uplink channel quality of the auxiliary carrier; determining to execute a switching operation based on the estimated quality of the uplink channel of the auxiliary carrier; determining that the auxiliary carrier is an auxiliary carrier to be switched; and triggering UE to execute the switching operation, and switching an original uplink carrier to the auxiliary carrier to be switched for scheduling. The uplink auxiliary carrier of the UE is managed according to the channel quality of the auxiliary carrier, and the uplink service transmission flow of the UE is improved. 本发明实施例公开了一种用于载波聚合的上行传输方法、装置及基站。该用于载波聚合的上行传输方法中，
