MULTI-CELL UPLINK COOPERATIVE COMMUNICATION METHOD AND BASE STATION

摘要

Embodiments of the present invention provide a multi-cell uplink coordinated communication method and a base station, relate to the communications field, and can resolve a problem that joint data receiving cannot be performed when an exchange latency between cells is large. The method is as follows: A first base station predicts retransmission scheduling information for UE in advance, and sends the retransmission 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 when the UE retransmits data. Alternatively, a first base station predicts new transmission scheduling information according to a service type of UE, and sends the new transmission scheduling information to a second base station in advance, so that the second base station having a large exchange latency may receive the new transmission scheduling information, 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. The embodiments of the present invention are used for uplink coordinated communication when an exchange latency between cells is large.
