Abstract
The present document discloses a method, apparatus and system for indicating downlink resources of a coordinated multi-point network in an LTE system. The method includes: determining a control station/cell and a service station/cell of a User Equipment (UE); and indicating through signaling that a Physical Downlink Shared Channel (PDSCH) of the UE occupies radio resources of the service station/cell in a control region, whereby a start position of the PDSCH allocated for the UE by the service station/cell is the first symbol of a subframe, and when a resource mapping in the control region is performed, the PDSCH does not occupy Resource Elements (REs) occupied by a Cell Reference Signal (CRS), a Physical Control Format Indicator Channel (PCFICH), a Physical Hybrid-ARQ Indicator Channel (PHICH) of a station/cell where the PDSCH is located, and a Physical Downlink Control Channel PDCCH of the UE.
