RE-TRANSMISSION CONTROL METHOD, COMMUNICATION SYSTEM, AND DEVICE

摘要

A re-transmission control method, a communication system, and a device. The re-transmission control method comprises: the media access control (MAC) entity of an eNB transmits an MAC protocol data unit (PDU) to a UE through a hybrid automatic repeat request (HARQ) channel, said MAC PDU content including handover command information; the MAC entity of the eNB receives from the UE HARQ acknowledgment information transmitted through the HARQ channel; if the HARQ channel used by the MAC entity of the eNB to transmit the MAC PDU and the HARQ channel used by the UE to transmit the HARQ acknowledgment information are the same, the radio link control entity of the eNB is notified to stop transmitting the handover command information. Air interface resources are conserved.
