Summary:Techniques for transmitting and receiving data with spatial interference mitigation in a wireless network are described. In one design of transmitting data with spatial interference mitigation, a first station (e.g., a cell) may receive spatial feedback information (SFI) from a second station (e.g., an interfered UE) that is not communicating with the first station. The second station may also receive precoding information from a third station (e.g., a served UE). The first station may send a data transmission to the third station based on the precoding information and the SFI in order to reduce interference to the second station. In one design, the SFI may include spatial nulling information. The first station may send the data transmission based on the spatial nulling information to steer the data transmission in a direction away from the second station.
