摘要: Techniques for transmitting null pilots to support interference estimation in a wireless network are described. A pilot is non-transmission on designated time-frequency resources by cell or cluster of cells supporting cooperative transmission UE. The received power the from may be indicative other cells. In one design, determine sending cell. transmit (i.e., send no transmissions) allow UEs estimate out-of-cluster interference. Some all same resources. receive and channel information UE data based and/or information. Remaining reduce
