    Abstract: Embodiments of the present invention provide an uplink inter-cell coordination method. The method include: determining, by a first base station, whether first uplink data sent by user equipment UE and forwarded by a second base station is received before a first moment; if the first base station determines that the first uplink data is not received before the first moment, performing, by the first base station, demodulation and decoding of second uplink data received from the UE, and if an incorrect demodulation and decoding result is obtained, suspending, by the first base station, an HARQ process and determining whether the first uplink data forwarded by the second base station is received between the first moment and a second moment, where the second moment is later than the first moment.

    Abstract: Embodiments of the present invention provide a multi-cell uplink coordinated communication method and a base station. The method includes: A first base station predicts retransmission scheduling information or new transmission scheduling information for UE, and sends the retransmission scheduling information or the new transmission scheduling information to a second base station having a large exchange latency, so that a cell of the second base station serves as a coordinating cell to perform joint data receiving. Alternatively, a second base station having a large latency in exchange with a first base station buffers air interface data that is within fixed duration before any moment, so that the second base station having a large exchange latency may obtain corresponding air interface data according to scheduling information, to perform joint data receiving. Thus a problem that joint data receiving cannot be performed when an exchange latency between cells is large can be resolved.

    Abstract: Embodiments of the present invention provide an uplink interference processing method, device and system. The method includes: receiving, by a first network device, information about second UE that is transmitted by a second network device; reconstructing uplink air interface data of the second UE according to the information about the second UE when uplink air interface data of the first UE is parsed incorrectly after first uplink air interface data is received, and obtaining the reconstructed uplink air interface data of the second UE; clearing the reconstructed uplink air interface data of the second UE from the first uplink air interface data to obtain second uplink air interface data; and parsing the second uplink air interface data according to information about the first UE, and obtaining a parsing result of the uplink air interface data of the first UE.
