Abstract: The embodiments of the present application disclose a method and a device for scheduling a resource in coordinated multi-point transmission and relate to the field of the wireless communications, so as to reduce the delay of a non-center coordination scheduling solution under the coordinated multi-point CoMP transmission and improve the scheduling efficiency. The solution comprises: a serving base station determining, according to a preset result of a negotiation with a coordinated base station, a final precoding matrix the coordinated base station prohibits; scheduling a resource according to channel state information (CSI) reported by a user terminal and the final precoding matrix the coordinated base station prohibits, and the coordinated base station scheduling the resource according to the CSI reported by the user terminal and the final precoding matrix the coordinated base station prohibits. By using the solution, the efficiency of the resource scheduling can be improved.

Abstract: The present disclosure provides a scheduling method, a coordinated-transmission node and a CCN for downlink coordinated-transmission. The scheduling method at a coordinated-transmission node side includes: receiving, by a coordinated-transmission node, scheduling privilege information corresponding to a downlink time-frequency resource from a CCN, the scheduling privilege information corresponding to the downlink time-frequency resource indicating a scheduling privilege of the coordinated-transmission node over the downlink time-frequency resource; and performing, by the coordinated-transmission node, the scheduling in accordance with the received scheduling privilege information and the latest CSI reported by the terminal. According to the embodiments of the present disclosure, the CCN merely determines the scheduling privilege of each coordinated-transmission node over the downlink time-frequency resource, and each coordinated-transmission node performs the scheduling in accordance with its scheduling privilege and the latest CSI reported by the terminal that is connected to the coordinated-transmission node.
