  • Publication number: 20190090265
    Abstract: The present invention discloses a data transmission method of a full-duplex system, a user equipment, and a base station. The UE is allowed to initiate full-duplex transmission, and it is unnecessary for the eNB to initiate full-duplex transmission. Before the initiation, the UE does not need to notify the eNB of buffer and preparation statuses of the UE. That is, the UE does not need to send related signaling to the eNB, thereby alleviating load of an entire LTE communications system, avoiding overload during data transmission, and reducing a transmission delay.
