摘要： A method, a network device, and a system for determining resource mapping in CoMP transmission are disclosed. The method includes: the cooperative cells that perform CoMP transmission for a UE negotiate a mapping rule used by the cooperative cells when the status of the CoMP transmission of the UE changes, where the mapping rule includes the number of and position of OFDM symbols allocated to a PDCCH domain and/or a data channel domain; and the negotiated mapping rule is notified to the UE. In this embodiment, before the downlink signals are transmitted, the mapping rule used by each cooperative cell for CoMP transmission is negotiated between the cooperative cells, and therefore, the UE can accurately receive the signal sent by multiple cooperative cells and the performance of CoMP transmission in the system is improved.
