  • 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.

  • Patent number: 10218458
    Abstract: A method of link adaptation is described including establishing, using a first serving point, a multi-user full duplex mode wherein the multi-user full duplex mode enables a downlink to a first wireless device and an uplink from a second wireless device. The first serving point requests from the first wireless device a first channel quality indicator indicating channel quality between the serving point and the first wireless device in a full duplex time period and a second channel quality indicator indicating channel quality between the serving point and the first wireless device in non-full duplex time period. The full duplex mode is evaluated using the first and second channel quality indicators. At least one parameter of the full duplex mode is adjusted based on the evaluating.
