The invention discloses a method for informing load state, when the medium access control protocol data unit MAC e element PDU need retransmission control, E - DCH MAC - D data stream retransmission timer dedicated channel corresponding to the medium enhanced access start base station; monitoring station in the E - DCH MAC - D flow retransmission timer timeout, meet the conditions of setting load state notification, the base station load status notification control radio network controller CRNC. The invention also discloses a corresponding device, which is located in the base station and comprises a E - DCH MAC - D stream retransmission timer unit and a notification unit. The invention informs CRNC of the load state of the Node B so that the CRNC can understand the load state of the Node B in time, and carries out load balancing in time according to the control strategy.
