摘要:
Techniques for supporting Coordinated MultiPoint (CoMP) transmission are described. For CoMP transmission, multiple cells may simultaneously send one or more data streams to one or more UEs on the same time-frequency resources based on short-term channel feedback from at least one UE to at least two cells. In an aspect, a semi-static configuration may be used by a set of cells for CoMP transmission to a UE. The semi-static configuration may indicate resource elements available to the set of cells to send CoMP transmission to the UE. The available resource elements may be determined based on a maximum number of TDM control symbols for all cells in the set and resource elements used for cell-specific reference signals by the cells in the set. A cell in the set may send data on the available resource elements to the UE for the CoMP transmission.
